| molineus cati n. sp. (nematoda, trichostrongylina, molineoidea), a parasite of feral cats, felis catus linnaeus, 1758 in south africa. | a new species of the genus molineus cameron, 1923 was recovered from feral cats, felis catus linnaeus, 1758, in mpumalanga province, south africa. because of a caudal bursa with rays of the 2-1-2 type, but with the extremities of rays 4 nearer those of rays 3 than those of rays 5, the new species is closely related to seven neotropical molineus spp., four parasitic in primates, two parasitic in mustelidae and one a parasite of procyonidae. amongst these species, only molineus barbaris cameron, 1 ... | 2000 | 11131118 |
| interspecific interaction and predator avoidance behavior in response to tayra (eira barbara) by mantled howler monkeys (alouatta palliata). | this paper reports the response of one howler monkey group (alouatta palliata) to a group of potential predators, the tayra (eira barbara). the apparently successful predator avoidance behavior of the monkeys was recorded in detail. we observed a group of four adult tayras moving around the alouatta group displaying a species-typical aggressive behavioral pattern. the two adult females of the howler group successfully chased the tayras away by repeatedly moving closer to the mustelids and even f ... | 2002 | 12426467 |
| ticks (acari: ixodida) on wild carnivores in brazil. | the present study reports field data of ticks infesting wild carnivores captured from july 1998 to september 2004 in brazil. additional data were obtained from one tick collection and from previous published data of ticks on carnivores in brazil. during field work, a total of 3437 ticks were collected from 89 cerdocyon thous (crab-eating fox), 58 chrysocyon brachyurus (maned wolf), 30 puma concolor (puma), 26 panthera onca (jaguar), 12 procyon cancrivorus (crab-eating raccoon), 4 speothos venati ... | 2005 | 16082932 |
| interactions between tayras (eira barbara) and red-handed howlers (alouatta belzebul) in eastern amazonia. | two tayras (eira barbara) were observed attacking an infant red-handed howler (alouatta belzebul) on an island in eastern brazilian amazonia, as a nearby adult male watched passively. in a separate incident, four tayras were seen attacking a subadult female on the ground. tayras were also observed in the vicinity of the two howler study groups on a number of occasions over a 9-month period. during this same period, the two groups lost a third of their members, including infants and subadults, an ... | 2007 | 16944250 |
| molecular detection of paracoccidioides brasiliensis in road-killed wild animals. | paracoccidioides brasiliensis infections have been little studied in wild and/or domestic animals, which may represent an important indicator of the presence of the pathogen in nature. road-killed wild animals have been used for surveillance of vectors of zoonotic pathogens and may offer new opportunities for eco-epidemiological studies of paracoccidiodomycosis (pcm). the presence of p. brasiliensis infection was evaluated by nested-pcr in tissue samples collected from 19 road-killed animals; 3 ... | 2008 | 17885959 |
| associations between primates and other mammals in a central amazonian forest landscape. | little information exists on mixed-species groups between primates and other mammals in neotropical forests. in this paper, we describe three such associations observed during an extensive large-vertebrate survey in central amazonia, brazil. mixed-species groups between a primate species and another mammal were observed on seven occasions between squirrel monkeys (saimiri cf. ustus) and either south american coatis (nasua nasua) or tayras (eira barbara) and between brown capuchins (cebus apella) ... | 2008 | 18306981 |
| efficiency of box-traps and leg-hold traps with several bait types for capturing small carnivores (mammalia) in a disturbed area of southeastern brazil. | capturing small carnivores is often necessary for obtaining key ecological data. we compared the efficiency of box and leg-hold traps, using live and dead bait, to capture six carnivore species (herpailurus yagouaroundi (e. geoffroyi, 1803), leopardus tigrinus (schreber, 1775), nasua nasua (linnaeus, 1766), cerdocyon thous (linnaeus, 1766), eira barbara (linnaeus, 1758), and galictis cuja (molina, 1782)). the use of leg-hold traps significantly increased the capture rate of carnivores (5.77%) an ... | 2007 | 18457140 |
| captive-born cotton-top tamarins (saguinus oedipus) respond similarly to vocalizations of predators and sympatric nonpredators. | what types of cues do callitrichid primates use to detect and respond to predators? do they respond to predator-specific cues or to more general cues? the evidence for these questions remains conflicting. we presented captive-born and reared cotton-top tamarins with no previous exposure to predators (or predator cues) with vocalizations from three potential predators of cotton-top tamarin in the wild (white hawk, jaguar, and tayra) and with vocalizations from sympatric nonpredators (black-faced ... | 2008 | 18473378 |
| [seasonal evaluation of mammal species richness and abundance in the "mário viana" municipal reserve, mato grosso, brasil]. | we evaluated seasonal species presence and richness, and abundance of medium and large sized mammalian terrestrial fauna in the "mário viana" municipal biological reserve, nova xavantina, mato grosso, brazil. during 2001, two monthly visits were made to an established transect, 2,820 m in length. records of 22 mammal species were obtained and individual footprint sequences quantified for seasonal calculation of species richness and relative abundance index (x footprints/km traveled). all 22 spec ... | 2006 | 18491629 |
| predation and predation attempts on red titi monkeys (callicebus discolor) and equatorial sakis (pithecia aequatorialis) in amazonian ecuador. | anecdotal reports of predation as well as observed predation attempts and rates of animal disappearance provide some of the most relevant data for evaluating the influence that predation risk may have on primate behavioural ecology. here, we report rates of disappearance from six groups of red titi monkeys (callicebus discolor) and two groups of equatorial sakis (pithecia aequatorialis) followed over a period of four and a half years at a lowland site in amazonian ecuador. we also describe the f ... | 2010 | 20639644 |
| ticks and rickettsiae from wildlife in belize, central america. | the agents of spotted fevers in latin america are rickettsia rickettsii, r. parkeri, rickettsia sp. strain atlantic rainforest, and r. massiliae. in continental central america, r. rickettsii remains the only known pathogenic tick-borne rickettsia. in the present study, ticks were collected from wild mammals in natural areas of belize. besides providing new data of ticks from belize, we investigated rickettsial infection in some of these ticks. our results provide ticks harboring rickettsial age ... | 2016 | 26831147 |

| serological evidence of infection by leishmania (leishmania) infantum (synonym: leishmania (leishmania) chagasi) in free-ranging wild mammals in a nonendemic region of the state of são paulo, brazil. | concerns about the interface between wildlife, domestic animals, and humans in the transmission of visceral leishmaniasis (vl) have been growing due to natural or anthropogenic environmental changes. in this context, investigations of the infection in wild mammals are important to assess their exposure to the vector and the parasite. a study of anti-leishmania (leishmania) infantum antibodies was carried out using the direct agglutination test (dat) on 528 free-ranging wild mammals of 38 species ... | 2015 | 26418884 |
| the role of fragmentation and landscape changes in the ecological release of common nest predators in the neotropics. | loss of large mammalian carnivores may allow smaller mesopredators to become abundant and threaten other community members. there is considerable debate about mesopredator release and the role that other potential factors such as landscape variables and human alterations to land cover lead to increased mesopredator abundance. we used camera traps to detect four mesopredators (tayra, eira barbara; white-nosed coati, nasua narica; northern raccoon, procyon lotor; and common opossum, didelphis opos ... | 2014 | 25071989 |
| mitochondrial genomes reveal the pattern and timing of marten (martes), wolverine (gulo), and fisher (pekania) diversification. | despite recent advances in understanding the pattern and timescale of evolutionary diversification in the marten, wolverine, fisher, and tayra subfamily guloninae (mustelidae, carnivora), several important issues still remain contentious. among these are the phylogenetic position of gulo relative to the subgenera of martes (martes and charronia), the phylogenetic relationships within the subgenus martes, and the timing of gulonine divergences. to elucidate these issues we explored nucleotide var ... | 2014 | 25132128 |
| prospective thinking in a mustelid? eira barbara (carnivora) cache unripe fruits to consume them once ripened. | the ability of nonhuman animals to project individual actions into the future is a hotly debated topic. we describe the caching behaviour of tayras (eira barbara) based on direct observations in the field, pictures from camera traps and radio telemetry, providing evidence that these mustelids pick and cache unripe fruit for future consumption. this is the first reported case of harvesting of unripe fruits by a nonhuman animal. ripe fruits are readily taken by a variety of animals, and tayras mig ... | 2011 | 21739130 |
| fibrocartilaginous emboli in a tayra (eira barbara): a case report. | an 8-yr-old male tayra (eira barbara) was presented with acute onset of pelvic limb paralysis. radiography was unremarkable. neurologic examination showed signs consistent with an intramedullary lesion between the second thoracic and fifth lumbar spinal cord segments. the animal's condition did not improve after 4 days of aggressive glucocorticoid therapy, and euthanasia was performed. histologic examination of the spinal cord showed amorphous emboli suggestive of cartilaginous fragments within ... | 1998 | 10065859 |
| local and scientific knowledge for assessing the use of fallows and mature forest by large mammals in se brazil: identifying singularities in folkecology. | local ecological knowledge (lek) has been discussed in terms of its similarities to and its potential to complement normative scientific knowledge. in this study, we compared the knowledge of a brazilian quilombola population regarding the habitat use and life habits of large mammals with in situ recordings of the species. we also tested the hypothesis that quilombola lek has a special focus on the anthropogenic portion of the landscape. | 2014 | 24410840 |
| atlantic-camtraps: a dataset of medium and large terrestrial mammal communities in the atlantic forest of south america. | our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the neotropical region based on camera trapping studies. the dataset comprises 170 surveys of medium to large terrestrial mammals using camera traps conducted in ... | 2017 | 28857166 |
| sylvatic host associations of triatominae and implications for chagas disease reservoirs: a review and new host records based on archival specimens. | the 152 extant species of kissing bug include important vectors of the debilitating, chronic, and often fatal chagas disease, which affects several million people mainly in central and south america. an understanding of the natural hosts of this speciose group of blood-feeding insects has and will continue to aid ongoing efforts to impede the spread of chagas disease. however, information on kissing bug biology is piecemeal and scattered, developed using methods with varying levels of accuracy o ... | 2017 | 28948106 |
| active anti-predator behaviour of red titi monkeys (plecturocebus cupreus). | due to their inconspicuous behaviour and colouration, it has been assumed that titi monkeys' main anti-predator behaviour is passive crypsis and hiding. so far, active predator mobbing has been documented only for black-fronted titi monkeys, callicebusnigrifrons. here we report for the first time mobbing behaviour of red titi monkeys, plecturocebus cupreus (previously callicebus cupreus), as reaction to an ocelot (leopardus pardalis) and a boa constrictor. we also report other active anti-predat ... | 2019 | 32110716 |
| the reservoir system for trypanosoma (kinetoplastida, trypanosomatidae) species in large neotropical wetland. | distinct species of trypanosoma have been documented sharing the same hosts in different environments in intricate transmission networks. knowing this, this study investigated the role of different hosts in the transmission cycles of trypanosoma species in the pantanal biome. the mammals were sampled from november 2015 to october 2016. we sampled a total of 272 wild mammals from 27 species belonging to six orders and 15 families, and three species of triatomines (n = 7). we found high parasitemi ... | 2019 | 31356788 |
| determining carnivore habitat use in a rubber/forest landscape in brazil using multispecies occupancy models. | understanding the factors that influence the presence and distribution of carnivores in human-dominated agricultural landscapes is one of the main challenges for biodiversity conservation, especially in landscapes where setting aside large protected areas is not feasible. habitat use models of carnivore communities in rubber plantations are lacking despite the critical roles carnivores play in structuring ecosystems and the increasing expansion of rubber plantations. we investigated the habitat ... | 2018 | 29659594 |
