| amino acid sequences of the alpha and beta chains of adult hemoglobin of the slender loris, loris tardigradus. | alpha and beta chains from adult hemoglobin of the slender loris (loris tardigradus) were isolated by amberlite cg-50 column chromatography. after s-aminoethylation, both chains were digested with trypsin and the amino acid sequences of the tryptic peptides obtained were analyzed. further, the order of these tryptic peptides in each chain was deduced from their homology with the primary structures of alpha and beta chains of human adult hemoglobin. comparing the primary structures of the alpha a ... | 1978 | 100490 |
| patterns of retinal terminations and laminar organization of the lateral geniculate nucleus of primates. | autoradiographic tracing procedures have been used to study the organization of retinogeniculate axons in seven primates, i.e., four species of new world monkeys, one species of old world monkeys and two species of prosimians. these data suggest that the basic primate pattern of geniculate lamination consists of two parvocellular layers, two magnocellular layers, and two poorly developed and highly variable superficial (s) layers which are ventrally located. ocular input to each member of each o ... | 1978 | 102662 |
| primate repetitive dnas: evidence for new satellite dnas and similarities in non-satellite repetitive dna sequence properties. | repetitious dna sequences have been isolated from a number of the primates in in both suborders anthropoidea and prosimii by hydroxy-apatite chromatography at a cot of 10. in addition to finding previously unreported possible at-rich satellite dnas in orangutan, gibbon, rhesus and slow loris a clear similarity to human dna was found in the nonsatellite repetitious dna sequence properties of the primates in the suborder anthropoidea. this is based on the presence of the hydroxyapatitie isolated 1 ... | 1979 | 114378 |
| dicentric yields induced by gamma-radiation and chromosome arm number in primates. | to evaluate the effect of the chromosome arm number on the yield of dicentric chromosomes, frequencies of gamma-ray-induced chromosome aberrations were examined with peripheral lymphocytes from three different primate species, saimiri sciureus (arm number, 77), macaca fascicularis (arm number, 83) and nycticebus coucang (arm number, 99). irradiated blood samples were cultured by the same standard technique as that commonly used for human lymphocytes. the yields of dicentrics and dicentrics plus ... | 1977 | 405578 |
| the anatomical relations of the ductus vomeronasalis and the occurrence of taste buds in the papilla palatina of nycticebus coucang (primates, prosimiae) with remarks on strepsirrhinism. | nycticebus coucang is typically strepsirrhine. this condition is basically the same in all prosimians except tarsius. the rhinarium shows a labial part; the marked furrow in its median plane clefts the margin of the upper lip. the latter is attached to the gum between the median incisors by means of paired folds (not corresponding to a frenulum labii superioris). the labial cleft is continued in the sulcus papillae palatinae. the ductus vomeronasalis opens into the ductus nasoplatinus which, in ... | 1977 | 415935 |
| activity of nocturnal primates: influences of twilight zeitgebers and weather. | the time of onset of activity of bush babies (galago senegalensis), slow lorises (nycticebus coucang), and an owl monkey (aotus trivirgatus) living in outdoor enclosures usually fell in certain illuminance ranges of dusk and kept pace with seasonal progressions of sunset time. influences of cloud cover were variable, but excessive heat and cold were inhibitory. accurate endogenous timekeeping and reliance on the most stable zeitgeber apparently maintain activities in synchrony with the rhythmica ... | 1976 | 813298 |

| a comparative survey of the mast cells of the mammalian brain. | a search for mast cells has been made in the brains of 18 mammalian species in 13 families in the orders insectivora, primates, rodentia and carnivora. in the larger animals, only the diencephalon and olfactory bulbs were examined. mast cells were identified by virtue of their heparin-containing granules, which are stained by alcian blue 8gx and, metachromatically, by toluidine blue 0. within the cerebral parenchyma, mast cells were confined to the dorsal diencephalon of erinaceus europaeus (hed ... | 1976 | 819404 |
| evaluation and re-evaluation of genetic radiation hazards in man. ii. the arm number hypothesis and the induction of reciprocal translocations in man. | the arm number hypothesis proposed by brewen and collagues in 1973 has been examined in the light of information thus far available from mammalian studies. in experiments with peripheral blood lymphocytes (radiation in vitro), a linear relationship between dicentric yield and the effective chromosome arm number of the species was obtained in the mouse, chinese hamster, goat, sheep, pig, wallaby and man. however, the data are not consistent with such a relationship in several primate species (ma ... | 1976 | 819823 |
| twilight zeitgebers, weather, and activity of nocturnal primates. | bush babies (galago senegalensis), slow lorises (nycticebus coucang), and an owl monkey (aotus trivirgatus) in outdoor enclosures usually began activity in certain illuminance ranges of dusk and accommodated to seasonal changes in sunset time. influences of cloud cover were variable, but marked heat and cold were inhibitory. accurate endogenous timekeeping and a reliance on the most stable zeitgeber apparently maintain activities in synchrony with the rhythmically changing environment. | 1976 | 821830 |
| the intercollicular area of the inferior colliculus. | to study the somatosensory input to the inferior colliculus, lesions were made in the dorsal column nuclei of the hedgehog, tree shrew, slow loris, marmoset and african green monkey, and spinal cord of the hedgehog, tree shrew and slow loris. the degenerating fibers stained with silver impregnation methods. the dorsal column system projects primarily to an area lateral to the central nucleus of the inferior colliculus, whereas the spinotectal projection is primarily to the medial region in the h ... | 1976 | 825188 |
| somatic sensory cortex of llama (lama glama). | the somatic sensory cortex (si and sii) was mapped in llamas using microelectrode mapping methods developed earlier in a study of si of the slow loris. projections to si from the llama's prehensile browsing lips were differentially enlarged when compared to those reported for sheep. in llama, sii was reversed in its mediolatreal pattern from that reported for sii in most other mammals. fissural landmarks reliably demarcated different projections within si, between si and sii and between si or si ... | 1976 | 990910 |
| review of sarcocystosis in malaysia. | sarcocystis is a tissue coccidian with an obligatory two-host life cycle. the sexual generations of gametogony and sporogony occur in the lamina propria of the small intestine of definitive hosts which shed infective sporocysts in their stools and present with intestinal sarcocystosis. asexual multiplication occurs in the skeletal and cardiac muscles of intermediate hosts which harbor sarcocystis cysts in their muscles and present with muscular sarcocystosis. in malaysia, sarcocystis cysts have ... | 1991 | 1822870 |
| current status of food-borne parasitic zoonoses in singapore. | parasitic infections adopt a rather low profile in the highly urbanized setting in singapore. very few food-borne parasitic infections are encountered. apart from a few reports of infections with clonorchis/opisthorchis, taenia spp. and hydatid disease, there are no other citations of such helminthic infections. seroprevalence surveys have shown the presence of toxoplasmosis in local meat animals (sheep, pigs and cattle) and toxoplasma strains have been isolated from the pig, tree shrew (tupaia ... | 1991 | 1822903 |
| giardia isolates from primates and rodents display the same molecular polymorphism as human isolates. | five giardia isolates from primates and rodents were grown axenically and compared by different electrophoretic techniques. one isolate from a lemur (slow loris) contained a dsrna virus also found in some of the giardia of human origin. using ethidium bromide stained gels and also southern blots hybridized with a rdna probe, two profiles of restriction fragment length polymorphism were found in the animal giardia, which are identical to two profiles found previously in strains of human origin. i ... | 1990 | 1968225 |
| axenic isolation of giardia strains from primates and rodents. | during the examination of animals at the poznan zoological gardens, attempts were made to isolate giardia strains. using an in vitro excystation procedure, eight samples of cysts from animals with asymptomatic giardiasis were inoculated on bi-s-33 medium. the ease of isolation and axenization of giardia was surprising; five axenic isolates of giardia, belonging to the g. duodenalis morphological group, were established from primates (slow loris, lesser slow loris and siamang) and from rodents (g ... | 1990 | 2343527 |
| distinct subfamilies of primate l1gg retroposons, with some elements carrying tandem repeats in the 5' region. | two subfamilies of l1 elements, differing dramatically in the first 1.2 kb of sequence at their 5' ends, were identified in the prosimian primate, galago garnetti. interesting patterns of sequence similarity were observed between the galago subfamilies, and with the l1s from human and from another prosimian, the slow loris. furthermore, members of one of the subfamilies have six to eight tandemly repeated units of 73 bp, starting about 730 bp from their 5' ends. such tandem repeats have not been ... | 1988 | 3399387 |
| the chromosomes of nycticebus coucang (boddaert, 1785) (primates: prosimii). | the high-quality karyotype of a specimen of nycticebus coucang is described and illustrated. the x chromosome is found to be indistinguishable from that of the greater galagos, and may represent a synapomorphic trait. the y chromosome is a medium to small submetacentric (3.2% tcl) and constitutes one of the larger y chromosomes known in primates. n. coucang is found to have multiple nor-bearing chromosomes in contrast to the single pair found in galagine and catarrhine monkeys. since a single no ... | 1987 | 3504803 |
| the medial terminal nucleus of the monkey: evidence for a 'complete' accessory optic system. | the retinal projection to the medial terminal nucleus of the accessory optic system of the monkey was examined in several primate species which had received intraocular injections of [3h]proline or [3h]fucose. these data show that the medial terminal nuclei of the slow loris, marmoset monkey, and squirrel monkey all receive a sparse input from the contralateral retina. | 1986 | 3947982 |

| pterygodermatites nycticebi (nematoda: spirurida) in golden lion tamarins. | pterygodermatites nycticebi (syn rictularia nycticebi), a spirurid nematode first described in the slow loris (nycticebus coucang), recently has been associated with morbidity and mortality in the golden lion tamarin (leontopithecus rosalia rosalia) collection at the national zoological park. adult worms were found in the lumen of the small intestine with their anterior ends embedded in the mucosa. larvae, when present, were deeper in the submucosa. a few heavily infected animals developed profo ... | 1983 | 6406763 |
| scapula of apidium phiomense: a small anthropoid from the oligocene of egypt. | a scapular fragment from the upper fossil wood zone, quarry i, fayum depression, egypt, is assigned to the taxon apidium phiomense. this animal may have approximated the size of galago crassicaudatus or nycticebus coucang, as predicted by regressing body weight on glenoid surface area and fossa length for an assortment of living primates. morphometric values for spinoglenoid, axilloglenoid, and axillospinal angles indicate locomotor affinities of a. phiomense with colobine monkeys. other nonmetr ... | 1983 | 6407926 |
| cerebral response to medullary pyramid stimulation in the rabbit. | the response evoked in the cerebral cortex of the rabbit by stimulation of the medullary pyramid was studied electrophysiologically. the response was everywhere surface-positive and began 2-3 ms after the stimulus. it exceeded 1 mv in amplitude and generally lasted 2-4 ms. maps of the response showed it to extend throughout the anterior one-third of the cortex (in the 'motor' cortex) and into adjacent tissue, including the limbic cortex. although it depended on antidromic conduction in pyramidal ... | 1984 | 6535628 |
| learning set formation in slow lorises (nycticebus coucang). | in primates, learning set formation has been reported in various simian species, but in only few prosimian species. the formation of visual discrimination learning set was tested on a nocturnal prosimian species, slow lorises (nycticebus coucang). their performance was higher than that of some new world monkeys. this confirmed the suggestion from the data on black lemurs (lemur macaco) that there is an overlap between prosimians and simians in learning set ability. | 1983 | 6629231 |

| multiple l1 progenitors in prosimian primates: phylogenetic evidence from orf1 sequences. | one of the uncertainties regarding the evolution of l1 elements is whether there are numerous progenitor genes. we present phylogenetic evidence from orf1 sequences of slow loris (nycticebus coucang) and galago (galago crassicaudatus) that there were at least two distinct progenitors, active at the same time, in the ancestor of this family of prosimian primates. a maximum parsimony analysis that included representative l1s from human, rabbit, and rodents, along with the prosimian sequences, reve ... | 1993 | 8411207 |
| [hypometabolism in aotus trivirgatus (primates, plathyrhini, cebidae)]. | the standard metabolism of aotus trivirgatus (night monkey, owl monkey) is 22.5 to 46.2 per cent below kleiber's prevision curve for mammals, which applies to other cebid monkeys like saimiri sciureus and alouatta. however the metabolic rate of aotus is not reduced to the extent found in two hypometabolic prosimians perodicticus potto and nycticebus coucang. the low metabolism in aotus is associated with a normal body temperature and a thick fur of high insulating power. these results are discus ... | 1977 | 146561 |
| milk composition reflects pattern of maternal care in prosimian primates. | hypothesized relationships between milk composition and life history traits were examined by analyzing mid-lactation milks of seven lemurs (eulemur fulvus, e. macaco, e. rubriventer, e. mongoz, varecia variegata, hapalemur griseus, lemur catta), three bushbabies (otolemur crassicaudatus, o. garnettii, galago moholi), and two lorises (nycticebus coucang, loris tardigradus); partial data were also obtained for the lemuroid cheirogaleus medius. there were no significant differences in milk composit ... | 1997 | 9057965 |
| cytomegalovirus in the parotid gland of a slow loris, nyctecibus coucang. | sporadic enlarged cells with both nuclear and cytoplasmic viruses were found in the intralobular ducts of the parotid salivary gland of an adult female slow loris; these ducts are homologous to striated ducts in the salivary glands of other primates. the duct cell nuclei contained reticular inclusions and virions in all stages of development. cytoplasmic virions were, in almost every case, confined to vacuoles; only a very few were free in the cytosol. the viruses conformed in ultrastructure to ... | 1997 | 9267053 |
| the monoclonal antibody h386f labels microglia in the retinal nerve fiber layer of several mammals. | the antibody h386f revealed microglia in the retinae of several species: owl monkey, slow loris, galago, ferret, raccoon, and tree shrew. the shape, size, and density of labeled microglia were identical to those labeled by ox-42 and ox-41, two antibodies specific for microglia, in both galago and owl monkey. the labeled microglia varied little in retinal location. there was remarkably little variability in density, shape, number, and size of the labeled microglia between species. all labeled mic ... | 1997 | 9278995 |
| meat-eating by adult female sumatran orangutans (pongo pygmaeus abelii). | information about meat-eating behavior by wild orangutans (pongo pygmaeus) is scant. the first article about such a case dates from 1981. since 1989, seven incidents of adult female sumatran orangutans eating slow lorises (nycticebus coucang) have been witnessed. three females from two study sites were involved. in three cases the females were seen catching the prey. there are too few cases to conclude whether this behavior is typically female. | 1997 | 9327098 |
| molecular evolution of an ancient mariner transposon, hsmar1, in the human genome. | a confident consensus sequence for hsmar1, the first mariner transposon recognized in the human genome, was generated using three genomic and 15 cdna sequences. it is thought to represent the ancestrally active copy that invaded an early primate genome. the consensus is 1287 base pairs (bp) long, has 30 bp perfect inverted terminal repeats (itrs), and encodes a 343 amino acid (aa) mariner transposase. each copy has diverged from the consensus largely independently of the others and mostly neutra ... | 1997 | 9461395 |
| molecular evolution of gh in primates: characterisation of the gh genes from slow loris and marmoset defines an episode of rapid evolutionary change. | pituitary growth hormone (gh), like several other protein hormones, shows an unusual episodic pattern of molecular evolution in which sustained bursts of rapid change are imposed on long periods of very slow evolution (near-stasis). a marked period of rapid change occurred in the evolution of gh in primates or a primate ancestor, and gave rise to the species specificity that is characteristic of human gh. we have defined more precisely the position of this burst by cloning and sequencing the gh ... | 2001 | 11357061 |
| characterization and phylogenetic relationship of prosimian mhc class i genes. | mhc class i cdna sequences from the most divergent primate group of extant primates compared to human, the suborder strepsirrhini (prosimians), are described. the sequences are derived from the gray mouse lemur (microcebus murinus) and the ring-tailed lemur (lemur catta), which are members of the malagasy lemuriformes, as well as from the pygmy slow loris (nycticebus pygmaeus), a prosimian from east asia. the m. murinus sequences have been analyzed in detail. analysis of the expression level, g/ ... | 2002 | 12486535 |

| molecular evolution of prolactin in primates. | pituitary prolactin, like growth hormone (gh) and several other protein hormones, shows an episodic pattern of molecular evolution in which sustained bursts of rapid change contrast with long periods of slow evolution. a period of rapid change occurred in the evolution of prolactin in primates, leading to marked sequence differences between human prolactin and that of nonprimate mammals. we have defined this burst more precisely by sequencing the coding regions of prolactin genes for a prosimian ... | 2005 | 15983870 |
| chromosome painting between human and lorisiform prosimians: evidence for the hsa 7/16 synteny in the primate ancestral karyotype. | multidirectional chromosome painting with probes derived from flow-sorted chromosomes of humans (homo sapiens, hsa, 2n = 46) and galagos (galago moholi, gmo, 2n = 38) allowed us to map evolutionarily conserved chromosomal segments among humans, galagos, and slow lorises (nycticebus coucang, nco, 2n = 50). in total, the 22 human autosomal painting probes detected 40 homologous chromosomal segments in the slow loris genome. the genome of the slow loris contains 16 sytenic associations of human hom ... | 2006 | 16323198 |
| kinematics of vertical climbing in lorises and cheirogaleus medius. | the type of climbing exhibited by apes and atelines is argued to have been important in the evolution of specialized locomotion, such as suspensory locomotion and bipedalism. however, little is known about the mechanics of climbing in primates. previous work shows that asian apes and atelines use larger joint excursions and longer strides than african apes and the japanese macaque, respectively. this study expands knowledge of climbing mechanics by providing the first quantitative kinematic data ... | 2006 | 16445966 |
| multidirectional chromosome painting reveals a remarkable syntenic homology between the greater galagos and the slow loris. | we report on the first reciprocal chromosome painting of lorisoids and humans. the chromosome painting showed a remarkable syntenic homology between otolemur and nycticebus. eight derived syntenic associations of human segments are common to both otolemur and nycticebus, indicative of a considerable period of common evolution between the greater galago and the slow loris. five additional robertsonian translocations form the slow loris karyotype, while the remaining chromosomes are syntenically e ... | 2006 | 16534804 |

| [cytogenetics of two lorisidae (nycticebus coucang and perodicticus potto). comparison with the lemurs and the simians (author's transl)]. | the karyotypes of two lorisidae (prosimians) nycticebus coucang and perodicticus potto have been studied, using many banding techniques. these karyotypes are compared with each other and also with those of microcebus murinus (lemur) and of cebus capucinus (simian, platyrrhine). the karyotype of m. murinus appears ancestral to the other. that of the lorisidae cannot be an intermediatry stage between the karyotypes of the lemurs and of the simians. an important part (12 p. cent) of the genome of n ... | 1979 | 115375 |
| ancestral loss of short wave-sensitive cone visual pigment in lorisiform prosimians, contrasting with its strict conservation in other prosimians. | mammals are basically dichromatic in color vision, possessing middle to long wave-sensitive (m/lws) and the short wave-sensitive (sws) cone opsins in the retina, whereas some nocturnal mammals lack functional sws opsins. prosimians, primitive primates consisting of three extant groups (lorisiformes, lemuriformes, and tarsiiformes), include many nocturnal species. among nocturnal prosimians, a species of lorisiforms, the greater galago (otolemur crassicaudatus), is known to lack a functional sws ... | 2004 | 15045486 |
| lateral bending of the lumbar spine during quadrupedalism in strepsirhines. | much research has been devoted to spinal kinematics of nonmammalian vertebrates, while comparatively little is known about the locomotor role of spinal movements in mammals, especially primates. this study, conducted at the duke university primate center, examines the function of lateral spinal bending during quadrupedal walking among a diverse sample of strepsirhines. the taxa studied include loris tardigradus (1), nycticebus coucang (1), n. pygmaeus (1), cheirogaleus medius (2), varecia varieg ... | 2001 | 11180987 |
| alcohol discrimination and preferences in two species of nectar-feeding primate. | recent reports suggest that dietary ethanol, or alcohol, is a supplemental source of calories for some primates. for example, slow lorises (nycticebus coucang) consume fermented nectars with a mean alcohol concentration of 0.6% (range: 0.0-3.8%). a similar behaviour is hypothesized for aye-ayes (daubentonia madagascariensis) based on a single point mutation (a294v) in the gene that encodes alcohol dehydrogenase class iv (adh4), the first enzyme to catabolize alcohol during digestion. the mutatio ... | 2016 | 27493777 |
| brief communication: effect of size biases in the coefficient of variation on assessing intraspecific variability in the prosimian skeleton. | this study examines the effect of a measurement size bias in coefficients of variation on the evaluation of intraspecific skeletal variability in a sample of eight prosimian species (eulemur fulvus, hapalemur griseus, lemur catta, varecia variegata, galago senegalensis, otolemur crassicaudatus, nycticebus coucang, and tarsius syrichta). measurements with smaller means were expected to have higher coefficients of variation (cvs) due to the impact of instrumental precision on the ability to assess ... | 2013 | 23900852 |
| epaxial muscle fiber architecture favors enhanced excursion and power in the leaper galago senegalensis. | galago senegalensis is a habitual arboreal leaper that engages in rapid spinal extension during push-off. large muscle excursions and high contraction velocities are important components of leaping, and experimental studies indicate that during leaping by g. senegalensis, peak power is facilitated by elastic storage of energy. to date, however, little is known about the functional relationship between epaxial muscle fiber architecture and locomotion in leaping primates. here, fiber architecture ... | 2015 | 26184388 |
| comparative histochemical study of prosimian primate hindlimb muscles. ii. populations of fiber types. | the populations of fiber types in hindlimb muscles of the tree shrew (tupaia glis), lesser bushbaby (galago senegalensis), and the slow loris (nycticebus coucang) were described and an attempt was made to correlate populations of fiber types and locomotor patterns. muscle fibers were assigned to one of the following groups: fast-twitch glycolytic (fg), fast-twitch oxidative-glycolytic (fog), and slow-twitch oxidase (so). histochemical techniques for the demonstration of alkaline- and acid-stable ... | 1981 | 6791489 |
| comparative histochemical study of prosimian primate hindlimb muscles. i. muscle fiber types. | the profiles of fiber types in hindlimb muscles from the tree shrew (tupaia glis), lesser bushbaby (galago senegalensis), and the slow loris (nycticebus coucang) were determined using histochemical techniques. fibers were classified as fast-twitch oxidative-glycolytic (fog), fast-twitch glycolytic (fg), slow-twitch oxidative (so), or fast-twitch oxidative (fo), according to reactions for alkaline-stable atpase, acid-stable atpase, alpha-glucan phosphorylase, reduced nicotinamide adenine dinucleo ... | 1981 | 6455915 |
| mad, bad and dangerous to know: the biochemistry, ecology and evolution of slow loris venom. | only seven types of mammals are known to be venomous, including slow lorises (nycticebus spp.). despite the evolutionary significance of this unique adaptation amongst nycticebus, the structure and function of slow loris venom is only just beginning to be understood. here we review what is known about the chemical structure of slow loris venom. research on a handful of captive samples from three of eight slow loris species reveals that the protein within slow loris venom resembles the disulphide ... | 2013 | 24074353 |

| trialling nutrient recommendations for slow lorises (nycticebus spp.) based on wild feeding ecology. | slow loris (nycticebus spp.) captive diets have been based on routine and anecdotes rather than scientific fact. the growing body of evidence contradicts the high fruit diet supported by such anecdotes. non-human primate nutrient requirements are grouped into new (based on the common marmoset callithrix jacchus) or old world (based on rhesus macaques macaca mulatta) primates. slow lorises are known to suffer from many health ailments in captivity such as dental disease, obesity, wasting and kidn ... | 2017 | 28444791 |
| distribution of interstitial telomeric sequences in primates and the pygmy tree shrew (scandentia). | it has been hypothesized that interstitial telomeric sequences (itss), i.e., repeated telomeric dna sequences found at intrachromosomal sites in many vertebrates, could be correlated to chromosomal rearrangements and plasticity. to test this hypothesis, we hybridized a telomeric pna probe through fish on representative species of 2 primate infraorders, strepsirrhini (lemur catta, otolemur garnettii, nycticebus coucang) and catarrhini (erythrocebus patas, cercopithecus petaurista, chlorocebus aet ... | 2017 | 28423373 |
| the estimated mechanical advantage of the prosimian ankle joint musculature, and implications for locomotor adaptation. | in this study we compared the power arm lengths and mechanical advantages attributed to 12 lower leg muscles across three prosimian species. the origins and insertions of the lower leg muscles in garnett's galago, the ring-tailed lemur, and the slow loris were quantified and correlated with positional behaviour. the ankle joint of the galago has a speed-oriented mechanical system, in contrast to that of the slow loris, which exhibits more power-oriented mechanics. the lemur ankle joint exhibited ... | 2013 | 23489408 |
| a comparison of auditory brainstem responses and behavioral estimates of hearing sensitivity in lemur catta and nycticebus coucang. | primates depend on acoustic signals and cues to avoid predators, locate food, and share information. accordingly, the structure and function of acoustic stimuli have long been emphasized in studies of primate behavioral and cognitive ecology. yet, few studies have addressed how well primates hear such stimuli; indeed, the auditory thresholds of most primate species are unknown. this empirical void is due in part to the logistic and economic challenges attendant on traditional behavioral testing ... | 2010 | 19938053 |
| density of muscle spindles in prosimian shoulder muscles reflects locomotor adaptation. | we examined the correlation between the density of muscle spindles in shoulder muscles and the locomotor mode in three species of prosimian primates: the slow loris (nycticebus coucang), garnett's galago (otolemur garnettii), and the ring-tailed lemur (lemur catta). the shoulder muscles (supraspinatus, infraspinatus, teres major, teres minor, and subscapularis) were embedded in celloidin and cut into transverse serial thin sections (40 microm); then, every tenth section was stained using the aza ... | 2006 | 17361082 |

| exudativory in the asian loris, nycticebus: evolutionary divergence in the toothcomb and m3. | slow lorises (nycticebus spp.) are obligate exudativores that gouge tree bark. dental adaptations for gouging within marmosets, the only other known primate obligate exudativore, are well-known but dental adaptations in nycticebus are largely unidentified. in an effort to more completely understand potential dental adaptions within nycticebus and the evolution of this dietary niche within primates as an order, the present study examined dental morphometrics in the asian lorises (nycticebus and l ... | 2015 | 26286661 |
| a survey of husbandry practices for lorisid primates in north american zoos and related facilities. | zoos and related facilities in north america currently manage five species in the primate family lorisidae: the greater (nycticebus coucang), bengal (n. bengalensis) and pygmy (n. pygmaeus) slow lorises, red slender loris (loris tardigradus), and potto (perodicticus potto). we used an online survey to describe institutional housing and husbandry practices for these species and assess the extent to which practices are consistent with established guidelines. our results show that most captive lori ... | 2013 | 23161761 |
| functional differentiation of long bones in lorises. | the external dimensions of the limb bones and the geometry of their midshaft cross-sections were determined for loris tardigradus and nycticebus coucang. relative cortical thickness, cortical area, and second moment of area were calculated and contrasted with locomotor stresses. the difference in shape-related strength of the bones between the smaller- and the larger-bodied species is more pronounced than can be expected from stresses acting during normal locomotion. the nycticebus skeleton has ... | 1989 | 2807094 |

| changes in the primate trade in indonesian wildlife markets over a 25-year period: fewer apes and langurs, more macaques, and slow lorises. | indonesia has amongst the highest primate species richness, and many species are included on the country's protected species list, partially to prevent over-exploitation. nevertheless traders continue to sell primates in open wildlife markets especially on the islands of java and bali. we surveyed 13 wildlife markets in 2012-2014 and combined our results with previous surveys from 1990-2009 into a 122-survey dataset with 2,424 records of 17 species. these data showed that the diversity of specie ... | 2015 | 26713673 |
| ontogeny of relationship of middle ear and temporomandibular (squamomandibular) joint in mammals. iii. morphology and ontogeny in scandentia and primates. | the ontogeny of the mandibular joint and the middle ear region was studied in tupaia javanica, microcebus murinus, nycticebus coucang and tarsius bancanus. during development, a passage connection was found between the mandibular condyle and meckel's cartilage that is produced by the primordium of the lateral pterygoid muscle. the articular disk is formed separately, and it appears later in development. a theory is presented on the interpretation of these findings. | 1990 | 2106204 |
| accessing local knowledge to identify where species of conservation concern occur in a tropical forest landscape. | conventional biodiversity surveys play an important role in ensuring good conservation friendly management in tropical forest regions but are demanding in terms of expertise, time, and budget. can local people help? here, we illustrate how local knowledge can support low cost conservation surveys. we worked in the malinau watershed, east kalimantan, indonesia, an area currently at risk of extensive forest loss. we selected eight species of regional conservation interest: rafflesia (rafflesia spp ... | 2013 | 23633002 |
| hypervariability of nucleolus organizer regions in bengal slow lorises, nycticebus bengalensis (primates, lorisidae). | slow lorises are a cryptic species complex, and thus genetic markers are needed to identify distinct evolutionary lineages or species. we examined the nucleolus organizer regions (nors) of bengal slow lorises (nycticebus bengalensis) using fish with 18s rdna (rdna-fish) and silver nitrate staining (ag-nor stain). ten individuals of the putatively single species n. bengalensis showed higher variability in localization than 3 other congeners, though their overall karyotypes were similar. the rdna- ... | 2016 | 27648559 |
| density and microhabitat use of bengal slow loris in primary forest and non-native plantation forest. | the extent of planted forests has greatly increased in the tropics, but their conservation value while assumed to be low, is largely unknown. we compared the density and microhabitat selection of a nocturnal arboreal primate, the bengal slow loris (nycticebus bengalensis), in mostly undisturbed, evergreen tropical forest to those in 15-18 year old acacia/leucaena plantations with significant secondary regrowth, and <15 year old plantations with little regrowth. based on estimates derived from di ... | 2010 | 20938966 |
| mother-infant interactions in slow lorises (nycticebus bengalensis) and pygmy lorises (nycticebus pygmaeus). | the study had three purposes: (1) to obtain information about mother-infant interactions in a rarely studied nocturnal prosimian, the pygmy loris (nycticebus pygmaeus); (2) to compare pygmy lorises with a closely related and better-studied nocturnal prosimian, the bengal slow loris (nycticebus bengalensis); and (3) to determine how the presence of a second offspring affected mother-infant interactions in pygmy lorises. three bengal slow loris mothers and 3 pygmy loris mothers served as subjects, ... | 2006 | 14605472 |
| a novel application of cultural consensus models to evaluate conservation education programs. | conservation professionals recognize the need to evaluate education initiatives with a flexible approach that is culturally appropriate. cultural-consensus theory (cct) provides a framework for measuring the extent to which beliefs are communally held and has long been applied by social scientists. in a conservation-education context, we applied cct and used free lists (i.e., a list of items on a topic stated in order of cultural importance) and domain analysis (analysis of how free lists go tog ... | 2017 | 28861944 |
| the seasonal feeding ecology of the javan slow loris (nycticebus javanicus). | to describe the strategy employed by exudativorous primates during seasonal shifts in food abundance using the javan slow loris as a model. males and females may cope differently as well as exploit fallback foods in different proportions. | 2017 | 28117494 |
| morphological convergence in the pubis of slow-moving primates and xenarthrans. | determining the functional significance of pubic rami is important for reconstructing locomotor behavior of fossil species. the slow loris pelvis, characterized by long pubic rami, is unusual among primates. long pubic rami may be related to increasing the moment arm of the abdominal musculature during ventroflexion after the termination of hindlimb suspension, which is a common component of slow arboreal quadrupedalism (aq). some extant xenarthran species are also slow aq taxa, and provide an i ... | 2016 | 27377428 |
| intraocular silicone ball implantation after evisceration in a slow loris (nycticebus coucang). | a slow loris, nycticebus coucang , was brought to ji dong beom animal hospital from the national institute of ecology due to globe enlargement and frequent blepharospasm of the right eye. ophthalmic diagnoses included glaucoma with posterior lens luxation and cataract. because this animal was on exhibition at the national institute of ecology, preservation of the eyeball by intraocular silicone implantation following evisceration rather than enucleation was selected. before the surgery, examinat ... | 2016 | 27468037 |
| is tickling torture? assessing welfare towards slow lorises (nycticebus spp.) within web 2.0 videos. | videos, memes and images of pet slow lorises have become increasingly popular on the internet. although some video sites allow viewers to tag material as 'animal cruelty', no site has yet acknowledged the presence of cruelty in slow loris videos. we examined 100 online videos to assess whether they violated the 'five freedoms' of animal welfare and whether presence or absence of these conditions contributed to the number of thumbs up and views received by the videos. we found that all 100 videos ... | 2015 | 26848764 |
| hibernation in the pygmy slow loris (nycticebus pygmaeus): multiday torpor in primates is not restricted to madagascar. | hibernation and short daily torpor are states of energy conservation with reduced metabolism and body temperature. both hibernation, also called multiday torpor, and daily torpor are common among mammals and occur in at least 11 orders. within the primates, there is a peculiar situation, because to date torpor has been almost exclusively reported for malagasy lemurs. the single exception is the african lesser bushbaby, which is capable of daily torpor, but uses it only under extremely adverse co ... | 2015 | 26633602 |
| diets high in fruits and low in gum exudates promote the occurrence and development of dental disease in pygmy slow loris (nycticebus pygmaeus). | asian slow lorises are found in zoos and rescue centres worldwide with nycticebus pygmaeus, the pygmy slow loris, boasting the largest population in captivity. diet are reportedly high in fruit and concentrates and low in insects and exudates. wild feeding studies place insects, nectar, and gums as the most important diet components. captive populations also show high incidences of health afflictions, many of which may be caused by nutrition. our study, aims at identifying a causative agent with ... | 2015 | 26339992 |
| meat-eating by a wild bornean orang-utan (pongo pygmaeus). | we present the first evidence for consumption of meat by a wild bornean orang-utan (pongo pygmaeus). meat-eating has been reported in sumatran orang-utans, specifically the hunting and consumption of slow lorises (nycticebus coucang), but loris-hunting behaviour has not been observed in the bornean species and meat of any species is essentially absent from their diet, with only two anecdotal reports of vertebrate meat consumption prior to this current finding in over 40 years of study. in august ... | 2015 | 26298471 |
| does toxic defence in nycticebus spp. relate to ectoparasites? the lethal effects of slow loris venom on arthropods. | the venom produced by slow lorises (nycticebus spp.) is toxic both intra- and inter-specifically. in this study we assessed the ecoparasite repellent properties of their venom. we tested venom from two indonesian slow loris species: nycticebus javanicus and nycticebus coucang. arthropods directly exposed to brachial gland secretions mixed with saliva from both species were immediately impaired or exhibited reduced activity (76%), and often died as a result (61%). we found no significant differen ... | 2015 | 25528386 |
| persistent viremia by a novel parvovirus in a slow loris (nycticebus coucang) with diffuse histiocytic sarcoma. | cancer is one of the leading health concerns for human and animal health. since the tumorigenesis process is not completely understood and it is known that some viruses can induce carcinogenesis, it is highly important to identify novel oncoviruses and extensively study underlying oncogenic mechanisms. here, we investigated a case of diffuse histiocytic sarcoma in a 22 year old slow loris (nycticebus coucang), using a broad spectrum virus discovery technique. a novel parvovirus was discovered an ... | 2014 | 25520709 |
| mapping the nasal airways: using histology to enhance ct-based three-dimensional reconstruction in nycticebus. | three-dimensional reconstructions of imaging data are an increasingly common approach for studying anatomical structure. however, certain aspects of anatomy, including microscopic structure and differentiating tissue types, continue to benefit from traditional histological analyses. we present here a detailed methodology for combining data from microct and histological imaging to create 3d virtual reconstructions for visualization and further analyses. we used this approach to study the distribu ... | 2014 | 25312369 |
| anaphylactic shock following the bite of a wild kayan slow loris (nycticebus kayan): implications for slow loris conservation. | asian slow lorises (nycticebus spp.) are one of few known venomous mammals, yet until now only one published case report has documented the impact of their venomous bite on humans. we describe the reaction of a patient to the bite of a subadult nycticebus kayan, which occurred in the mulu district of sarawak in 2012. | 2014 | 25309586 |
| interactions between a wild bornean orang-utan and a philippine slow loris in a peat-swamp forest. | all documented orang-utan-loris interactions have been from sumatra, where lorises were opportunistically preyed upon by orang-utans. in this paper, we describe two accounts of the bornean orang-utan (pongo pygmaeus wurmbii) interacting with the philippine slow loris (nycticebus menagensis). the interactions were by two adolescent female orang-utans. no attempts to catch the loris were observed on either occasion. neither interaction was hostile. during the second observation, which was more det ... | 2014 | 24781375 |
