“…The richness of medium and large terrestrial mammals of the Boqueirão da Onça (S = 26) presented a high value when compared to other localities, since recent inventories carried out in the Caatinga indicated the occurrence between seven and 29 species (Guedes et al, 2000;Freitas et al, 2011;Rocha et al, 2014;Dias & Bocchiglieri, 2016;Deiciellos, 2016;Dias et al, 2017;Freitas et al, 2017;Pereira & Peixoto, 2017;Marinho et al, 2018).…”

The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order to characterize the community of mammals of this region, considering species richness, we installed 80 camera-trap stations. With a sampling effort of 10,370 camera-days we recorded 28 species (22 wild and six domestic). Opportunistically, we recorded four mammals, resulting in a total richness of 32 species, five of which are included in the global list of endangered species, and seven in the national list. The results are significant, since the richness of wild mammals of the Boqueirão da Onça (S = 26) presented a high value when compared to other Caatinga localities. During the study we found evidence of human activities threatening the conservation of the region, such as poaching and deforestation. Therefore, there is an urgent need in the publication of the Management Plan of the recently created Boqueirão da Onça National Park, to minimize negative impacts on biodiversity and ensure the maintenance of ecological processes.

“…Consequently, there is a lack of data to answer most of the related questions. These difficulties have discouraged many researchers from studying the higher strata of the forests, limiting the surveys to no more than 2 m in height (Albuquerque et al, 2013;Carvalho & Oliveira, 2015;Delciellos, 2016;Helder-José et al, 2016;Leite & Costa, 2018).…”

The suspended pitfall demonstrates a new and simple mechanism to capture small arboreal and scansorial mammals. It is an arboreal version of the pitfalls traditionally used to capture terrestrial amphibians and reptiles. Buckets with bait inside are raised by a rope until they reach a tree branch at the desired height. Tests were performed in the Atlantic Forest at three different sites at the mouth of Doce River in Linhares, southeastern Brazil. In one of them suspended pitfalls were set up in the understory of a shaded cacao plantation (cabruca agroforest) in the branches of cacao trees between 2 and 3 m in height, and in the other they were placed in a native forest between 5 to 15 m in height. At the third site, suspended pitfalls were tested together with the other live traps used hitherto in the understory of other cabruca agroforest. The marsupials Didelphis aurita, Caluromys philander, Marmosa (Micoureus) paraguayana, Gracilinanus microtarsus, Marmosa murina and the rodent Rhipidomys mastacalis were captured by suspended pitfall. This live trap was capable of catching all sizes of small arboreal mammals, including juvenile individuals. This method proved to be functional for the capture of some small arboreal mammals and may be a complementary alternative for sampling in high forest strata.

“…Mammals are key components of the Caatinga ecosystem as they play an important role in forest maintenance and regeneration, and the structuring and functioning of biological communities (Carmignotto & Astúa 2017). The number of mammal inventories undertaken in this biome has increased in recent years (Feijó & Langguth 2013, Delciellos 2016, Marinho et al 2018). Nevertheless, knowledge on fauna and ecological processes is scarce when compared to other Brazilian biomes.…”

The state of Paraiba is one of those with the most degraded Caatinga that presents the large gap of knowledge concerning the mammal fauna. Mammals are among the taxa most affected by this. In this sense, we evaluated non-volant mammals’ richness and composition between March 2013 and February 2020 in a Caatinga fragment (121 ha). We used active search (336 hours) and camera traps (1,200 night traps). We recorded 20 species, including four threatened ones. Carnivora was the most representative order (7 species), followed by Rodentia (4 species). The richness of non-volant mammals found represents 35.6 % of the total number of such species in the Caatinga. This species richness is greater than that found in other studies in the state. The presence of these mammal species was mainly due to the recovering vegetation that resulted from the great planting effort and also due to cessation of hunt, cattle and sheep breeding that had existed on the farm for over thirty years. Our findings highlight the importance of this particular reserve due to the large number of species registered.
