Land-use changes lead to functional loss of terrestrial mammals in a Neotropical rainforest

Medium-sized and large mammals of the Floresta da Cicuta Area of Relevant Ecological Interest, a protected area in southeastern Brazil

“…The data presented here regarding composition, richness, and conservation status of mammal species in the ARIE-FC highlight the high biological value of this protected area. They also reinforce the importance of the small native forest fragments, which contribute significantly to increasing the diversity at the landscape level providing valuable habitats for many forest species and playing an important role as stepping stones and, thus, preventing local extinctions (Turner and Corlett 1996;Ribeiro et al 2009;Magioli et al 2021aMagioli et al , 2021b. Approximately half of the mammal species recorded in the ARIE-FC are classified under some threat level or are near or presumably threatened, stressing the importance of including the conservation value of the small fragments in specific management and conservation policies (Pellens et al 2009;Ribeiro et al 2009).…”

“…The increasing rate of habitat loss and fragmentation in the Atlantic Forest negatively affects mammals and their ecological functions (Magioli et al 2021a); therefore, field efforts are essential to obtain data on species richness and composition, which are the bases of many conservation and management actions (Costa et al 2005;Zipkin et al 2009).…”

Mammals of Cajuru State Forest and surroundings: a neglected but important Protected Area for the Cerrado conservation in the São Paulo state, Brazil

“…Many ecological processes mediated by medium and large-sized mammals have significant effects on the community structure of plants and can alter communities of different trophic levels (Estes et al 2011, Pérez-Méndez et al 2016, Lacher et al 2019. Despite their importance, medium and large-sized mammals are especially affected by habitat loss and fragmentation (Ceballos & Ehrlich 2012, Magioli et al 2021, hunting (Cardillo et al 2005), and illegal trade (Rosen & Smith 2010), being among the most vulnerable animal groups to the impacts of the Anthropocene (Dirzo et al 2014, Tucker et al 2018.…”

Ciência cidadã e modelos de distribuição de espécies para a conservação de aves ameaçadas

“…Devido à elevada riqueza e grande pressão antrópica, o bioma é um dos hotspots de biodiversidade mais ameaçados do planeta (MITTERMEIER; RYLANDS, 2018). As alterações antrópicas ocorridas no bioma desde a colonização do país, impactam diversos grupos de fauna e flora (MORANTE-FILHO et al, 2015;BOGONI et al, 2019;LIMA et al, 2020;MAGIOLI et al, 2021). Entre as aves, se considerarmos o número de táxons ameaçados (incluindo espécies e subespécies), aproximadamente 10% (N = 107 de 1035) estão em categorias de ameaça, segundo a lista brasileira de espécies ameaçadas (MMA, 2014).…”

“…A degradação dos habitats promove a extinção local ou global de espécies (CEBALLOS; EHRLICH; DIRZO, 2017; CEBALLOS; EHRLICH; RAVEN, 2020; DEVELEY; PHALAN, 2021) e suas funções ecológicas MAGIOLI et al, 2021), e consequentemente, impacta negativamente diversos serviços ecossistêmicos providos por áreas e recursos naturais, como o controle de pragas (BIANCHI; BOOIJ; TSCHARNTKE, 2006), provisão de água (DODDS; PERKIN; GERKEN, 2013) e estoque de carbono , além de aumentar a exposição à doenças infecciosas (WILKINSON et al, 2018;BARBIER, 2021). As extinções, porém, não ocorrem de maneira aleatória, e espécies com determinadas características morfológicas e funcionais são mais afetadas do que outras pela perda de habitat (DIRZO et al, 2014).…”
