diet of lowland tapir (tapirus terrestris) in el rey national park, salta, argentina.lowland tapir (tapirus terrestris) is the largest herbivore in the neotropics and, in argentina, it inhabits a variety of habitats from 100 to 2100 m asl. lowland tapirs importantly influence their habitat structure because they are selective browsers, seed predators and long-distance seed dispersers. however, increased knowledge of tapir ecology is necessary to support the conservation and management of the species in natural and human-modified environments. between jun 2002 and dec 2008 we ass ...201323586559
unveiling the diet of elusive rainforest herbivores in next generation sequencing era? the tapir as a case study.characterizing the trophic relationships between large herbivores and the outstanding plant diversity in rainforest is a major challenge because of their elusiveness. this is crucial to understand the role of these herbivores in the functioning of the rainforest ecosystems. we tested a non-invasive approach based on the high-throughput sequencing of environmental samples using small plant plastid sequences (the trnl p6 loop) and ribosomal its1 primers, referred to as dna metabarcoding, to invest ...201323560107
functional redundancy and complementarities of seed dispersal by the last neotropical megafrugivores.functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. large bodied frugivores may disperse similar plant species and have strong impact on plant recruitment in tropical forests. the two largest frugivores in the neotropics, tapirs (tapirus terrestris) and muriquis (brachyteles arachnoides) are potential candidates for functional redundancy on seed dispersal effectivene ...201323409161
escherichia coli-producing extended-spectrum beta-lactamase ctx-m-15 in a captive south american tapir (tapirus terrestris).only a few reports exist on the occurrence of resistant bacteria in zoo animals. therefore, an isolation of multiresistant escherichia coli from the lungs of a captive south american tapir (tapirus terrestris) lead to its characterization and further investigation of samples from animals inhabiting the same paddock and from the shared environment. the tapir suffered from an intermandibular abscess and pneumonia and was euthanatized after unsuccessful therapy, including administration of antibiot ...201323505722
morphological and molecular characterization and phylogenetic relationships of a new species of trypanosome in tapirus terrestris (lowland tapir), trypanosoma terrestris sp. nov., from atlantic rainforest of southeastern brazi.the lowland tapir (tapirus terrestris) is the largest brazilian mammal and despite being distributed in various brazilian biomes, it is seriously endangered in the atlantic rainforest. these hosts were never evaluated for the presence of trypanosoma parasites.201324330660
attractiveness of native mammal's feces of different trophic guilds to dung beetles (coleoptera: scarabaeinae).mammal feces are the primary food and nesting resource for the majority of dung beetle species, and larval development depends on the quantity and quality of that resource. physiological necessities, competitive interactions, and resource sharing are common and suggest that dung beetles may show preferences for feces of greater nutritional quality, which may in turn impact beetle assemblages and community structure. this study investigated whether attractiveness of dung beetles to different reso ...201425528749

kinship and social behavior of lowland tapirs (tapirus terrestris) in a central amazon landscape.we tested the hypothesis that tapirs tolerate individuals from adjacent and overlapping home ranges if they are related. we obtained genetic data from fecal samples collected in the balbina reservoir landscape, central amazon. samples were genotyped at 14 microsatellite loci, of which five produced high quality informative genotypes. based on an analysis of 32 individuals, we inferred a single panmictic population with high levels of heterozygosity. kinship analysis identified 10 pairs of full s ...201424671057
can enrichment make brazilian tapir spend more time on view to the public?one common visitor complaint in zoos is that the nonhuman animals are not visible. this problem needs to be resolved without compromising the animals' welfare; environmental enrichment could solve the problem. this study investigated whether enrichment would increase public exposure time of lowland tapir (tapirus terrestris) in the belo horizonte zoo in minas gerais, brazil. observations were made before (62 hr) and during (62 hr) the introduction of enrichment using focal animal sampling with i ...201525117174
dental lesions in the lowland tapir (tapirus terrestris).dental ailments, mandibular swelling, and dentoalveolar abscesses are common in tapirs, but knowledge about prevalence or etiology of these lesions in the tapiridae family in general, and in lowland tapirs (tapirus terrestris) in particular, is scarce. a recent study identified resorptive lesions of unknown etiology as a common problem in the malayan tapir (tapirus indicus). in order to investigate the type and prevalence of dental lesions occurring in lowland tapirs, and to compare these with f ...201526056895
seed dispersal and predation of buchenavia tomentosa eichler (combretaceae) in a cerrado sensu stricto, midwest brazil.the ecology of seed dispersal is critical to understand the patterns of distribution and abundance of plant species. we investigated seed dispersal aspects associated with the high abundance of buchenavia tomentosa in the serra azul state park (pesa). we estimated fruit production and conducted fruit removal experiments. we carried out diurnal and nocturnal observations on frugivory as well as germination tests. fruiting occurred in the dry season and totaled 1,365,015 ± 762,670 fruits.ha-1. b. ...201526602355
assessment of mammal reproduction for hunting sustainability through community-based sampling of species in the wild.wildlife subsistence hunting is a major source of protein for tropical rural populations and a prominent conservation issue. the intrinsic rate of natural increase. (rmax ) of populations is a key reproductive parameter in the most used assessments of hunting sustainability. however, researchers face severe difficulties in obtaining reproductive data in the wild, so these assessments often rely on classic reproductive rates calculated mostly from studies of captive animals conducted 30 years ago ...201627917537
a comparison of zoo animal behavior in the presence of familiar and unfamiliar recorded in domestic nonhuman animals, regular interactions between animals in zoos and keepers and the resulting relationship formed (human-animal relationship [har]) are likely to influence the animals' behaviors with associated welfare consequences. har formation requires that zoo animals distinguish between familiar and unfamiliar people. this ability was tested by comparing zoo animal behavioral responses to familiar (routine) keepers and unfamiliar keepers (participants in the "keeper f ...201626960022
phylogeography and spatial structure of the lowland tapir (tapirus terrestris, perissodactyla: tapiridae) in south america.we sequenced the mitochondrial cytochrome b gene of 141 lowland tapirs (tapirus terrestris) - representing the largest geographical distribution sample of this species studied across of south america to date. we compare our new data regard to two previous works on population structure and molecular systematics of t. terrestris. our data agree with the thoisy et al.'s work in (1) the northern western amazon basin was the area with the highest gene diversity levels in t. terrestris, being probably ...201626000940
does plan b work? home range estimations from stored on board and transmitted data sets produced by gps-telemetry in the colombian amazon.telemetry based on global positioning systems (gps) makes possible to gather large quantities of information in a very fine scale and work with species that were impossible to study in the past. when working with gps telemetry, the option of storing data on board could be more desirable than the sole satellite transmitted data, due to the increase in the amount of locations available for analysis. nonetheless, the uncertainty in the retrieving of the collar unit makes satellite-transmitted techn ...201629465908

measuring local depletion of terrestrial game vertebrates by central-place hunters in rural amazonia.the degree to which terrestrial vertebrate populations are depleted in tropical forests occupied by human communities has been the subject of an intense polarising debate that has important conservation implications. conservation ecologists and practitioners are divided over the extent to which community-based subsistence offtake is compatible with ecologically functional populations of tropical forest game species. to quantify depletion envelopes of forest vertebrates around human communities, ...201729040340
interspecific variation in the tetradactyl manus of modern tapirs (perissodactyla: tapirus) exposed using geometric morphometrics.the distal forelimb (autopodium) of quadrupedal mammals is a key morphological unit involved in locomotion, body support, and interaction with the substrate. the manus of the tapir (perissodactyla: tapirus) is unique within modern perissodactyls, as it retains the plesiomorphic tetradactyl (four-toed) condition also exhibited by basal equids and rhinoceroses. tapirs are known to exhibit anatomical mesaxonic symmetry in the manus, although interspecific differences and biomechanical mesaxony have ...201728707347
comparative cranial ontogeny of tapirus (mammalia: perissodactyla: tapiridae).skull morphology in tapirs is particularly interesting due to the presence of a proboscis with important trophic, sensory and behavioral functions. several studies have dealt with tapir skull osteology but chiefly in a comparative framework between fossil and recent species of tapirs. only one study examined an aspect of cranial ontogeny, development of the sagittal crest (holbrook. j zool soc lond 2002; 256; 215). our goal is to describe in detail the morphological changes that occur during the ...201728736808
genetic diversity of the captive asian tapir population in thailand, based on mitochondrial control region sequence data and the comparison of its nucleotide structure with brazilian tapir.the asian tapir (tapirus indicus) has been classified as endangered on the iucn red list of threatened species (2008). genetic diversity data provide important information for the management of captive breeding and conservation of this species. we analyzed mitochondrial control region (cr) sequences from 37 captive asian tapirs in thailand. multiple alignments of the full-length cr sequences sized 1268 bp comprised three domains as described in other mammal species. analysis of 16 parsimony-info ...201727159697
detection of leishmania (v) guyanensis in rhipicephalus (boophilus) microplus (acari: ixodidae) collected from pecari tajacu.previous studies identified the presence of leishmania infantum in rhipicephalus sanguineus and indicated the possibility that it could transmit leishmaniasis to a variety of hosts.201729161493
natural infection of the south american tapir ( tapirus terrestris ) by theileria equi.theileria equi is a tick-borne piroplasm considered endemic in equines in brazil. the cohabitation of domestic and wild animals in areas of extensive cattle breeding favors the close contact between different species and the sharing of vectors and, consequently, pathogens. we report the natural infection of a young south american tapir ( tapirus terrestris ) by t. equi in mato grosso do sul, brazil. although it was not possible to associate the clinical and hematologic status of the animal with ...201728151085
first evidences of amazonian wildlife feeding on petroleum-contaminated soils: a new exposure route to petrogenic compounds?videos recorded with infrared camera traps placed in petroleum contaminated areas of the peruvian amazon have shown that four wildlife species, the most important for indigenous peoples' diet (lowland tapir, paca, red-brocket deer and collared peccary), consume oil-contaminated soils and water. further research is needed to clarify whether amazonian wildlife's geophagy can be a route of exposure to petrogenic contamination for populations living in the vicinity of oil extraction areas and relyin ...201829103585
molecular identification of bartonella bacilliformis in ticks collected from two species of wild mammals in madre de dios: study the presence of bartonella bacilliformis in ticks collected from two wild mammals in madre de dios, peru.201829941013
determining the numbers of a landscape architect species (tapirus terrestris), using a landscape architect and a major seed disperser, the lowland tapir (tapirus terrestris) is an important indicator of the ecological health of certain habitats. therefore, reliable data regarding tapir populations are fundamental in understanding ecosystem dynamics, including those associated with the atlantic forest in brazil. currently, many population monitoring studies use invasive tagging with radio or satellite/global positioning system (gps) collars. these techniques can be costly and ...201829610711
phylogenetics, patterns of genetic variation and population dynamics of trypanosoma terrestris support both coevolution and ecological host-fitting as processes driving trypanosome evolution.a considerable amount of evidence has favored ecological host-fitting, rather than coevolution, as the main mechanism responsible for trypanosome divergence. nevertheless, beyond the study of human pathogenic trypanosomes, the genetic basis of host specificity among trypanosomes isolated from forest-inhabiting hosts remains largely unknown.201931604471
pathological findings in lowland tapirs (tapirus terrestris) killed by motor vehicle collision in the brazilian cerrado.the lowland tapir (tapirus terrestris) is the largest land mammal in south america. the species faces steady population decline due to poaching, habitat loss and fragmentation, road-kill, pesticide pollution, competition with domestic livestock and fires, among other threats. the lowland tapir is currently listed as vulnerable to extinction. little information is available about natural disease processes for the species. this study aimed to report the pathological findings recorded in a cohort o ...201931375157
three-dimensional ct examination of the forefoot and hindfoot of the hippopotamus and tapir during a semiaquatic walking.semiaquatic walking has resulted in the evolution of functional and morphological changes in various hoofed mammals, such as hippopotamus and brazilian tapir. the biomechanics of skilful walking in wetlands or at the bottom of a waterbody involve the medio-lateral opening and closing of the feet to effectively support and stabilize the body on soft ground and to reduce the water resistance during recovery stroke, respectively. we demonstrate that the opening and closing of the feet in hippopotam ...201930318610
intestinal ciliates (alveolata, ciliophora) in brazilian domestic horses (equus caballus l.) and a review on the ciliate communities associated with horses around the world.the aims of this study were to identify and quantify the gastrointestinal ciliates from brazilian domestic horses, to compare the data obtained with previous studies and to review data on ciliate communities associated with horses around the world. we used eight domestic horses, kept under extensive management. fecal samples were obtained immediately after defecation of animals and fixed in 18.5% formaldehyde. we identify 24 species of endosymbiotic ciliates, distributed in two subclasses, two o ...201931716156
clinical outcome and diagnostic methods of atypical mycobacteriosis due to mycobacterium avium ssp. hominissuis in a group of captive lowland tapirs (tapirus terrestris).tapirs seem particularly susceptible to mycobacterial infections, especially to tuberculosis caused by m. tuberculosis or m. bovis. in this case series, we report an infection with the non-tuberculous mycobacteria (ntm) species m. avium ssp. hominissuis (mah) in a group of four (2.2) captive lowland tapirs (tapirus terrestris). two female tapirs showed mild respiratory signs such as coughing and mucous sputum production for several years, one juvenile male tapir had to be euthanized due to sever ...202032780937
