Campos Gerais National Park lies within the Brazilian Atlantic Rainforest, a biodiversity hotspot and a priority for conservation. Current analysis, featuring a list of large and medium-sized mammal species in the park, was conducted between July 2013 and July 2014 and between May 2016 and April 2017. With a 780-hour sampling effort in active research and 157,516 hours in camera traps, 31 species of 17 families and 8 orders were recorded. Furthermore, 42% of recorded mammals in the park proved to be endangered species at state, national, or international levels. Two exotic and 1 domestic species were reported in the park. Results contribute towards an in-depth knowledge of the fauna in south Brazil and may help in further research work and management, complying with conservation proposals in the biodiversity of the Campos Gerais region in the state of Paraná, Brazil.

MEDIUM AND LARGE MAMMALS IN RIO VERMELHO MUNICIPAL ENVIRONMENTAL PROTECTION AREA, SANTA CATARINA, SOUTHERN BRAZIL: Most studies on medium and large mammals in the Brazilian Atlantic Forest are carried out in areas under full protection (as parks and biological reserves). Considering the continuing threats that the forest remnants are suffering, it is essential to carry out mammal surveys in protected areas for sustainable use. In order to evaluate the species richness and the relative frequency of medium and large mammals in the área de proteção ambiental municipal do Rio Vermelho – APARV (northern Santa Catarina state), methodologies of direct visualization and camera traps were used. The study was conducted from the beginning of 2015 to the end of 2019. In Santa Catarina state, there is only one study which sampling effort is comparable to the present one (7300 night-trap). Thirty-three native mammal species and two alien species (Canis familiaris and Lepus europaeus) were found. The species accumulation curve tended to stabilize at the beginning of the third year. Three species were responsible for more than half of the photographic records (Cerdocyon thous, Eira barbara and Procyon cancrivorus). In total, 33.3% of the species are classified in some category of threat, and three of these species are among the less recorded in Santa Catarina state (Tayassu pecari, Tapirus terrestris and Mazama nana). Our survey added 18 new occurrences to the APARV management plan. Only two of the 18 mammal surveys carried out previously in the Santa Catarina state recorded more species than our study. This is the second survey which was carried out in protected areas for sustainable use in Santa Catarina state. Our study contributes to the important knowledge that can be used in conservation measures. In this way, the APARV plays a fundamental role for the conservation of the Atlantic Forest mammals, constituting an important area favoring the population movements of mammals.

Piedras Blancas National Park, in southern Costa Rica, is an important component of two biological corridors connecting the Osa Peninsula (Corcovado National Park) and La Amistad International Park. Understanding the mammal community composition of Piedras Blancas will provide baseline data to evaluate the success of conservation efforts. We used camera traps and opportunistic observations to describe the medium-sized and large mammals of the park. We deployed camera traps for 1,440 trap nights (2016-2018). We detected 19 mammal species from seven orders and 13 families. Five species are globally threatened: Leopardus wiedii (Schinz, 1821), Saimiri oerstedii (Linnaeus, 1758), Ateles geoffroyi (Kuhl, 1820), Alouatta palliata (Gray, 1849), and Tapirus bairdii (Gill, 1865). We did not detect two locally threatened species, Panthera onca (Linnaeus, 1758) and Tayassu pecari (Link, 1795). Our research highlights a need for critical conservation work within the proposed biological corridor to support Costa Rica’s most threatened wildlife.

The Cerrado is the second largest Brazilian biome and only 2.8% is represented by protected areas. Considering the relevance of the Cerrado and Conservation Units in preserving the mammalian diversity, we provided the first assessment of the diversity of medium- and large-sized mammal species in the Chapada dos Veadeiros National Park (CVNP) and surroundings. We tested the effectiveness of the CVNP by assessing the difference in species composition within the park and its surroundings. We sampled CVNP in the rainy (October-December 2013) and dry seasons (March-June 2014) in order to characterize the seasonality within the community. We selected 36 sampling sites to evaluate the composition of the medium and large mammals in the CVNP and its surroundings, 18 in the CVNP and 18 in the park surroundings. We ordered mammalian composition and frequency of individuals data by using a Non-metric Multidimensional Scaling analysis (NMDS). We assessed the effect of season (dry and rainy seasons) and locality (within the CVNP and surroundings) on mammalian species richness with a two-way analysis of variance (Two-way ANOVA). We recorded 23 species, 13 within the CVNP and 17 species in its surroundings. Composition and frequency of records differed between dry and rainy seasons, with higher richness in the rainy season. Species’ composition and the frequency of records were also different between within the CVNP and its surroundings, with higher richness in the surroundings. These results provide information for the increase of the knowledge of mammalian ecology but also is useful as a tool for future strategies to the conservation of these species. More attention should be given to the monitoring of these species in the long term because this area still harbor some viable populations.

In many regions of sub Saharan Africa large mammals occur in human-dominated areas, yet their community composition and species-specific densities have rarely been described in areas occupied by traditional hunter-gatherers and pastoralists. Surveys of mammal populations in such areas provide important measures of biodiversity and provide ecological context for understanding hunting practices. Using a sampling grid centered on a Hadza hunter-gatherer camp and covering 36 km² of semi-arid savannah in northern Tanzania, we assessed mammals using camera traps (n = 19 stations) for c. 5 months (2,182 trap nights). In the study area (Tli’ika in the Hadza language), we recorded 36 wild mammal species, resembling a near complete mammal community. Rarefaction curves suggest that sampling effort was sufficient to capture mammal species richness. Species-specific densities were estimated using a random encounter model and site- and species’ body mass- specific estimates of the area sampled at each camera; confidence intervals were estimated using bootstrapping. Point estimates of densities varied by c. four orders of magnitude, from 0.003 ind./km² (African wild dog) to 27.5 ind./km² (Kirk’s dik dik). Densities of livestock (cattle, donkey, sheep and goat) were high, particularly when estimated using directly observed herd sizes. Cumulative biomass density of herbivorous livestock species exceeded that of all wild mammals by a factor of 3.3-38.7. We compare our study’s data to camera trap rates recorded in a fully protected area of northern Tanzania with similar precipitation (Lake Manyara National Park), revealing that abundance indices of most wildlife species in Tli’ika were much lower. We discuss how these data inform studies of Hadza hunting and models of hunter-gatherer foraging ecology and diet.

The state of Tocantins is located in Central Brazil. The northern extreme of this state corresponds to the southeastern portion of the Amazon biome, while it is covered primarily by Cerrado savanna, as well as the transition area between these two biomes. We provide a checklist of large- and medium-bodied mammals from four localities in Tocantins, update the list of species for the state, and compile the available information on their geographic distribution. We surveyed mammals at four sites during different periods (between 2010 and 2018), using camera traps and opportunistic observations. In spite of the differences in the sampling effort among the sites, we recorded 42 mammal species belonging to eight orders and 20 families. Our list includes rare and threatened species, such as the jaguar (Panthera onca), the giant anteater (Myrmecophaga tridactyla), and the lowland tapir (Tapirus terrestris). One species (Galictis cuja) was recorded in the state for the first time and the known range distribution of two others (Speothos venaticus and Alouatta caraya) was updated.

Temporal Overlap

Rapid and widespread biodiversity losses around the world make it important to survey and monitor endangered species, especially in biodiversity hotspots. Bukit Barisan Selatan National Park (BBSNP) is one of the largest conserved areas on the island of Sumatra, and is important for the conservation of many threatened species. Sumatran tigers (Panthera tigris sumatrae) are critically endangered and serve as an umbrella species for conservation, but may also affect the activity and distribution of other carnivores. We deployed camera traps for 8 years in an area of Bukit Barisan Selatan National Park (BBSNP) with little human activity to document the local terrestrial mammal community and investigate tiger spatial and temporal overlap with other carnivore species. We detected 39 mammal species including Sumatran tiger and several other threatened mammals. Annual species richness averaged 21.5 (range 19–24) mammals, and remained stable over time. The mammal order significantly affected annual detection of species and the number of cameras where a species was detected, while species conservation status did not. Tigers exhibited a diurnal activity pattern, and had the highest temporal overlap with marbled cats (Pardofelis marmorata), dholes (Cuon alpinus), and Malayan sun bears (Helarctos malayanus), but little overlap with other carnivores. These findings suggest that some smaller carnivores might be adjusting temporal activity to avoid tigers or mesocarnivores. The stable trends in richness of terrestrial mammal species show that BBSNP remains an important hotspot for the conservation of biodiversity.

Mammal Diversity

Mammal groups have a vast variety of habitats, which include aquatic, aerial, arboreal, and terrestrial. For terrestrial habitats, camera traps are used as a common technique to record mammals and other vertebrates and have been recently utilized to observe arboreal animals as well. Here, we compare the difference in mammal diversity between floor and canopy strata and evaluate the use of camera trapping in a lowland forest in central Amazon. We installed nine paired camera traps, one in the canopy stratum and other in the floor stratum, in the Alto Cuieiras Biological Reserve (Brazilian Amazon). With a sampling effort of 720 camera-days, we recorded 30 mammal species: nine in canopy strata, 14 in floor strata, and seven in scansorial strata (sharing both strata). On the forest floor, the species with the greatest abundance was Myoprocta acouchy; in the canopy, Isothrix paguros had the greatest abundance; and among the scansorial species, Proechymis sp. was the most abundant. Our results show the differences in mammal diversity between floor and canopy strata; canopy strata contained more small and frugivorous mammals. Although we obtained a relatively low sampling effort with the camera-trap method compared with other studies utilizing different techniques, our results were especially similar to those of previous studies that worked with canopy and floor strata. Thus, camera trap can be very effective for recording short periods of time, and this method is less physically exhaustive and expensive for researchers to study vertical strata.

RESUMENLos mamíferos carnívoros desempeñan un rol importante en la estructura de las comunidades; sin embargo, los estudios sobre este grupo son complicados debido a sus estilos de vida, por lo que aún existen vacíos de información biológica. En este estudio se utilizaron trampas cámara en cuatro localidades de la costa central de Oaxaca, México. El trabajo se efectuó de septiembre de 2009 a agosto de 2010, con un esfuerzo total de 1012 días/trampa. Se obtuvieron 160 registros fotográficos independientes de ochos especies de mamíferos carnívoros y respecto a las presas potenciales se registraron cinco especies de mamíferos, dos especies de reptiles y dos grupos (aves y ratones). De acuerdo al Índice de Abundancia Relativa obtenido, los carnívoros más abundantes fueron Spilogale pygmaea, Urocyon cinereoargenteus y Nasua narica, mientras que las presas potenciales más abundantes fueron Didelphis virginiana, Dasypus novemcinctus y el grupo de los ratones. El patrón de actividad de las especies registradas mostró que el 73.8% son de hábitos nocturnos. El ganado vacuno de libre pastoreo mostró una abundancia que podría tener impactos en el ambiente natural y el nivel de recursos disponibles para la fauna silvestre de la región.Palabras clave: Cámaras-trampa, Carnívora, Oaxaca, patrón de actividad, Tututepec.ABSTRACTCarnivorous mammals play an important role on the community structure, however information gaps exist on their current situation debt to their nocturnal habits, evasive behavior and low population densities.

The study was conducted from September 2009 to August 2010, with a total sampling effort of 1,012 trap/days. We obtained 160 independent photographs records of eights carnivorous mammal species and regarding potential prey we obtained five mammals species, two reptile species and two groups (birds and mice). According with the two Relative Abundance Index obtained Spilogale pygmaea, Urocyon cinereoargenteus y Nasua narica were the most abundant carnivorous mammals while that Didelphis virginiana, Dasypus novemcinctus and the mice group were the most abundant potential prey. The activity patterns of the species showed that 73.8% of them are nocturnal. The free range cattle showed an abundance that could have impacts in the natural environment and the level of resources available for the wildlife in the region.Key words: Camera-traps, Carnivora, Oaxaca, activity patterns, Tututepec.

Paired Design

Arboreal mammals form a diverse group providing ecologically important functions such as predation, pollination and seed dispersal. However, their cryptic and elusive nature, and the heights at which they live, makes studying these species challenging. Consequently, our knowledge of rainforest mammals is heavily biased towards terrestrial species, limiting our understanding of overall community structure and the possible impacts of human-induced disturbance. We undertook the first in-depth appraisal of an arboreal mammal community in Southeast Asia, using camera-traps set in unlogged and logged tropical rainforest in Sabah, Borneo. Using paired canopy and terrestrial camera-traps at 50 locations (25 in unlogged forest, 25 in logged), we assessed the effectiveness of camera-trapping at characterising the arboreal versus terrestrial community, and tested the influence of strata and forest type on community structure and composition. The paired design detected 55 mammal species across 15,817 camera-trap nights (CTNs), and additional canopy sampling in a subset of trees added a further two arboreal species to the inventory. In total, thirty species were detected exclusively by terrestrial camera-traps, eighteen exclusively by canopy camera-traps, and nine by units set at both heights, demonstrating significant differences between arboreal and terrestrial communities. This pattern was strongest in unlogged forest, reflecting greater structural diversity of this habitat, but held in logged forest as well. Species accumulation curves revealed that canopy camera-trapping significantly boosted species inventories compared to terrestrial-only sampling, and was particularly effective at detecting gliding mammals, rodents and primates. Canopy inventories took longer to reach an asymptote, suggesting that a greater sampling effort is required when deploying canopy camera-traps compared to those set on the ground. We demonstrate that arboreal mammals in Borneo’s rainforest form a diverse and distinct community, and can be sampled effectively using canopy camera-traps. However, the additional costs incurred by sampling in the canopy can be substantial. We provide recommendations to maximise sampling effectiveness, while bringing down costs, to help encourage further study into one of the last frontiers of tropical forest research.

Capture Rates

Eleven mammal census sites were selected in four different Afrotemperate Forest types in the Garden Route National Park, South Africa. At each site, an array of eight camera traps was deployed along trails for between 28 and 45 days. Based on accumulation curves, this was generally sufficient for recording most of the focal mammal species at each site. Only 12 mammal (≥ 1 kg) species were recorded, two of which were primarily wetland species. The most widely captured taxa were bushbuck, Tragelaphus scriptus (all 11 sites); and caracal, Caracal caracal (10 sites). The most frequently photographed species were bushbuck (40%) and chacma baboon, Papio ursinus (22%). The number of species and total capture rates did not differ (P > 0.10) between dry (scrub and high) forests and moist (medium-moist to wet) forests, or between small (< 41 km²) forests and a large forest complex. However, at species level, the capture rates of caracal and vervet monkey, Chlorocebus pygerythus; were significantly lower (P ≤ 0.05) in the large forest complex than in small forests, whilst those of bushpig, Potamochoerus larvatus; were higher. Trapping cycles of between 28 and 45 days, which recorded the highest number of threatened and protected South African species, were from small forests.Conservation implications: The role of small forests in the conservation of mammals in the Garden Route National Park should be investigated further, because relatively high numbers of threatened and protected South African mammal species were recorded in these locations.
