Context
Habitat loss is widely recognized as the main driver of biodiversity loss around the globe, yet the effects of habitat fragmentation on biodiversity have been extensively debated in recent years.

Objectives
We used a robust dataset of medium and large-sized mammals to test (a) the Habitat Amount Hypothesis, which postulates that species richness can be mainly predicted by the total amount of habitat surrounding the sampling ...

Spatial predictors and species’ traits: evaluating what really matters for medium-sized and large mammals in the Atlantic Forest, Brazil Koninklijke Maatschappij voor Dierkunde van Antwerpen

Elaine Rios da Silva, Maíra Benchimol, Kristel De Vleeschouwer, Eliana Cazetta
Abstract Habitat loss and the conversion of natural environments to anthropogenic land uses are among the main drivers of biodiversity decline worldwide. The remaining habitats are inserted in highly modified landscapes, presenting contrasting patch and landscape features. Understanding species’ responses to these anthropogenic land-use changes is essential for informing conservation planning. We evaluate which spatial predictors (measured at ...

The role of protected and unprotected forest remnants for mammal conservation in a megadiverse Neotropical hotspot Koninklijke Maatschappij voor Dierkunde van Antwerpen

M. Magioli, Elaine Rios da Silva, Maíra Benchimol, D.C. Casanova, A.S. Ferreira, Oscar J. Rocha, F.R.D. Melo, M.P. Dias, G. Narezi, M.O. Crepaldi, et al.
The Brazilian Atlantic Forest of Southern Bahia is a megadiverse region given its remarkable number of species and endemism. Despite being a priority region for biodiversity conservation, the role of protected and unprotected forest remnants for long-term species conservation is unknown. Here, we unveil the main patterns of occurrence and distribution of medium- and large-sized mammals in remnants of the Atlantic Forest of Southern Bahia, to ...

Diurnal frugivores on the Bromeliaceae Aechmea depressa LB Sm. from Northeastern Brazil: the prominent role taken by a small forest primate Koninklijke Maatschappij voor Dierkunde van Antwerpen

Talita Fontoura, Eliana Cazetta, Wander do Nascimento, Lilian Catenacci, Kristel De Vleeschouwer, Becky Raboy
Little is lcnown about frugivory of epiphytes. We investigated diurnal frugivores consuming Aechmea depressa, an endemic species from Southern Bahia, Brazil, through 67 hours of observation on three fruiting individuals. Infructescences were visited for 2% of the time and only by golden-headed lion tamarins (GHLTs; Leontopithecus chrysomelas). Aechmea depressa invests on physical defense to retain fruits for prolonged periods, however, GIALTs ...
