a molecular phylogeny of the felidae: immunological distance.the phylogenetic distances between 34 of the 37 extant species of felidae were estimated using albumin immunological distances (aid). albumins from ten cat species were used to prepare antisera in rabbits. a consensus phylogeny was constructed from a matrix of reciprocal aid measurements using four distinct phylogenetic algorithms. a series of one-way measurements using the ten index antisera and those 24 species for which albumins were available (but antisera were not), permitted addition of th ...198528561961
adaptive differences in the body proportions of large felids.body proportions of eight species of large felids were studied and the relationship between their morphology, habitat structure and habitat utilization was analyzed. both panthera onca and neofelis nebulosa are exclusive forest dwellers (found exclusively in high densly structured habitats). these felids have the relatively shortest anterior limbs and lumbar spine. in addition, p. onca has the relatively shortest posterior limbs of the large felids, while the posterior limbs of n. nebulosa are r ...1976973541
how individual links affect network stability in a large-scale, heterogeneous metacommunity.elucidating how dispersal and landscape connectivity influence metacommunity stability will shed light on natural processes structuring ecosystems and help prioritize conservation actions in an increasingly fragmented world. much of the theoretical and mathematical development of the metacommunity concept has been based on simplified experimental systems or simulated data. we still have limited understanding of how variation in the habitat matrix and species-specific differences in dispersal abi ...201627859156
chemical immobilization of free-ranging and captive sunda clouded leopards (neofelis diardi) with two anesthetic protocols: medetomidine-ketamine and tiletamine-zolazepam.there is currently no available information regarding the veterinary management of sunda clouded leopards (neofelis diardi), either in captivity or in the wild. in this study, 12 sunda clouded leopards were anesthetized between january 2008 and february 2014 for medical exams, and/or gps-collaring. seven wild-caught individuals were kept in captivity and 5 free-ranging animals were captured by cage traps. two anesthesia combinations were used: medetomidine-ketamine (m-k) or tiletamine-zolazepam ...201728904261
scent marking in sunda clouded leopards (neofelis diardi): novel observations close a key gap in understanding felid communication behaviours.intraspecific communication is integral to the behavioural ecology of solitary carnivores, but observing and quantifying their communication behaviours in natural environments is difficult. our systematic literature review found that basic information on scent marking is completely lacking for 23% of all felid species, and information on 21% of other felid species comes solely from one study of captive animals. here we present results of the first systematic investigation of the scent marking be ...201627739507
the making of a monster: postnatal ontogenetic changes in craniomandibular shape in the great sabercat smilodon.derived sabercats had craniomandibular morphologies that in many respects were highly different from those of extant felids, and this has often been interpreted functionally as adaptations for predation at extreme gape angles with hypertrophied upper canines. it is unknown how much of this was a result of intraspecific postnatal ontogeny, since juveniles of sabercats are rare and no quantitative study has been made of craniomandibular ontogeny. postnatal ontogenetic craniomandibular shape change ...201222235326
geographical variation in and evolutionary history of the sunda clouded leopard (neofelis diardi) (mammalia: carnivora: felidae) with the description of a new subspecies from borneo.recent morphological and molecular studies led to the recognition of two extant species of clouded leopards; neofelis nebulosa from mainland southeast asia and neofelis diardi from the sunda islands of borneo and sumatra, including the batu islands. in addition to these new species-level distinctions, preliminary molecular data suggested a genetic substructure that separates bornean and sumatran clouded leopards, indicating the possibility of two subspecies of n. diardi. this suggestion was base ...201121074625
influence of living status (single vs. paired) and centrifugation with colloids on the sperm morphology and functionality in the clouded leopard (neofelis nebulosa).the objectives of the present study were to evaluate sperm characteristic of captive clouded leopards in thailand and examine the structural and functional properties of sperm after selection with the single-layer centrifugation (slc) method. twenty-two ejaculates from 11 captive clouded leopards (four housed with access to a female in estrus, and seven housed singly) were collected and assessed for semen traits during 2013 to 2015. twelve fresh ejaculates were chosen from seven males, and each ...201627568458
mitigation of sperm tail abnormalities using demembranation approach in the clouded leopard (neofelis nebulosa).clouded leopards (neofelis nebulosa) produced high proportion of abnormal spermatozoa (mainly tail defects) that can limit sperm movement and conception. the study aimed to better identify the origin of those defects using a demembranation approach. ejaculates (1-2 ejaculations/male; n = 9) were allocated to simple washing (control; resulting in 11.7% ± 1.9% coiled tails) and processed through colloid centrifugation to reduce the number of sperm with tail defects (treatment, resulting in 5.9% ±  ...201727758006
characterization of multiple pathways modulating aggression in the male clouded leopard (neofelis nebulosa).breeding clouded leopards (neofelis nebulosa) ex situ has been a challenge, primarily due to extreme and often fatal male aggression toward females. this study's aim was to determine the degree to which two possible mechanisms-serotonergic pathways and circulating testosterone levels-affect aggressive behavior. male clouded leopard behavioral and hormonal data were collected during a series of behavior tests administered before and after treatment with either an anxiety-reducing tricyclic antide ...201627588696
histologic and immunohistochemical characterization of pheochromocytomas in 20 clouded leopards ( neofelis nebulosa).clouded leopards in north american zoological institutions have a high frequency of pheochromocytomas and were identified in 32 of 70 (45%) animals necropsied. archival sections of adrenal gland from 20 adult clouded leopards with unilateral or bilateral pheochromocytomas collected between 1984 and 2011 were examined by light microscopy and immunohistochemistry, and case demographics were reviewed. affected leopards were older than 10 years of age (mean, 16 years; range, 11-19 years), and males ...201727543451
neocortical neuronal morphology in the siberian tiger (panthera tigris altaica) and the clouded leopard (neofelis nebulosa).despite extensive investigations of the neocortex in the domestic cat, little is known about neuronal morphology in larger felids. to this end, the present study characterized and quantified the somatodendritic morphology of neocortical neurons in prefrontal, motor, and visual cortices of the siberian tiger (panthera tigris altaica) and clouded leopard (neofelis nebulosa). after neurons were stained with a modified golgi technique (n = 194), dendritic branching and spine distributions were analy ...201627098982
comparison of subjective well-being and personality assessments in the clouded leopard (neofelis nebulosa), snow leopard (panthera uncia), and african lion (panthera leo).the study of subjective well-being in nonhuman animals is growing in the field of psychology, but there are still only a few published studies and the focus is on primates. to consider whether the construct of subjective well-being could be found in another mammal, this study aimed to assess subjective well-being in felids and to examine its association with personality. personality is one of the strongest and most consistent predictors of well-being in humans. this relationship could have impor ...201726983676
