英文摘要	Caatinga's conservation and biodiversity are threatened due to the intensification of anthropic activities and climate change. The mammals have different responses to seasonal and anthropic changes, however particularly in Caatinga, these effects are still poorly understood. We assessed the influence of anthropic (distance from urban areas and wind farms), environmental (distance from water), and seasonal (Normalized Difference Vegetation Index (NDVI) and land surface temperature (LST)) variables on the number of records and richness of medium and large-sized mammals in Brazilian Caatinga. We used camera traps in 2016-2017 and 2018-2019, estimated the variation (cv) of NDVI and LST, and generated Euclidean distance maps to anthropic and environmental variables at 250, 500, and 1000 m spatial scales. We performed Generalized Linear Models, used the Akaike information criterion, and calculated model averaging to assess the strength and direction of effect and the uncertainties of the winner models, respectively. The distance from wind farms and maximum LST had a noticeable effect on the number of records and total richness. The distance from wind farms had a negative effect on the records of Dicotyles tajacu and a positive effect on the records of Leopardus pardalis and richness. The maximum LST had a negative effect on the records of L. pardalis and a positive effect on the records of Puma concolor and Cerdocyon thous. Our results emphasize that an unsustainable expansion of wind farms is likely to compromise mammal diversity. We found an opposite pattern for some species regarding LST. However, it is important to highlight that the conservation of vegetation areas on the top of mountains and springs, and the installation of artificial water sources are important strategies to mitigate the impacts of high temperatures on mammals' biodiversity in Caatinga.Abstract in Portuguese is available with online material. A conserva & ccedil;& atilde;o e a biodiversidade da Caatinga est & atilde;o amea & ccedil;adas devido a intensifica & ccedil;& atilde;o das atividades antr & oacute;picas e das mudan & ccedil;as clim & aacute;ticas. Os mam & iacute;feros t & ecirc;m diferentes respostas & agrave;s mudan & ccedil;as sazonais e antr & oacute;picas. No entanto, esses efeitos ainda s & atilde;o pouco entendidos, especificamente na Caatinga. Neste estudo, estimamos a influ & ecirc;ncia das vari & aacute;veis antr & oacute;picas (dist & acirc;ncia de & aacute;reas urbanas e de fazendas e & oacute;licas), ambiental (dist & acirc;ncia de fontes de & aacute;gua) e sazonais (& Iacute;ndice de Vegeta & ccedil;& atilde;o por Diferen & ccedil;a Normalizada - IVDN e Temperatura da Superf & iacute;cie da Terra-TST) no n & uacute;mero de registros e riqueza de mam & iacute;feros de m & eacute;dio e grande porte na Caatinga brasileira. N & oacute;s utilizamos dados de armadilhas fotogr & aacute;ficas de 2016-2017 e 2018-2019, estimamos a varia & ccedil;& atilde;o (cv) do IVDN e TST e geramos mapas de dist & acirc;ncia euclidiana para as vari & aacute;veis antr & oacute;picas e ambiental em escalas espaciais de 250, 500 e 1000 m. N & oacute;s rodamos modelos lineares generalizados, utilizamos o crit & eacute;rio de informa & ccedil;& atilde;o de Akaike e calculamos a m & eacute;dia dos modelos para estimar a for & ccedil;a e a dire & ccedil;& atilde;o do efeito e as incertezas dos modelos ganhadores, respectivamente. A dist & acirc;ncia das fazendas e & oacute;licas e a TST m & aacute;xima tiveram um efeito percept & iacute;vel no n & uacute;mero de registros e riqueza. A dist & acirc;ncia das fazendas e & oacute;licas teve um efeito negativo nos registros de Dicotyles tajacu e um efeito positivo nos registros de Leopardus pardalis e riqueza. A TST m & aacute;xima teve um efeito negativo nos registros de Leopardus pardalis e um efeito positivo nos registros de Puma concolor e Cerdocyon thous. Nossos resultados enfatizam que uma expans & atilde;o insustent & aacute;vel das fazendas e & oacute;licas provavelmente comprometer & aacute; a diversidade de mam & iacute;feros. N & oacute;s encontramos um padr & atilde;o oposto para algumas esp & eacute;cies referente a TST. Entretanto, & eacute; importante evidenciar que a conserva & ccedil;& atilde;o das & aacute;reas de vegeta & ccedil;& atilde;o no topo das montanhas e das nascentes, assim como, a instala & ccedil;& atilde;o de fontes de & aacute;gua artificiais s & atilde;o importantes estrat & eacute;gias para mitigar os impactos das altas temperaturas na biodiversidade de mam & iacute;feros na Caatinga.
