Journal ArticleDOI
Time-lag in biological responses to landscape changes in a highly dynamic Atlantic forest region
Jean Paul Metzger,Alexandre Camargo Martensen,Marianna Dixo,Luís Carlos Bernacci,Milton Cezar Ribeiro,Ana Maria G. Teixeira,Renata Pardini +6 more
TL;DR: The results demonstrate that landscape history can strongly affect the present distribution pattern of species in fragmented landscapes, and should be considered in conservation planning.
Journal ArticleDOI
Using ecological thresholds to evaluate the costs and benefits of set-asides in a biodiversity hotspot
Cristina Banks-Leite,Cristina Banks-Leite,Renata Pardini,Leandro Reverberi Tambosi,William D. Pearse,Adriana A. Bueno,Roberta Thomaz Bruscagin,Thais Helena Condez,Marianna Dixo,Alexandre Toshiro Igari,Alexandre Camargo Martensen,Jean Paul Metzger +11 more
TL;DR: It is shown that an annual investment equivalent to 6.5% of what Brazil spends on agricultural subsidies would revert species composition and ecological functions across farmlands to levels found inside protected areas, thereby benefiting local people, and efforts to secure the future of this and other biodiversity hotspots may be cost-effective.
Journal ArticleDOI
Habitat fragmentation reduces genetic diversity and connectivity among toad populations in the Brazilian Atlantic Coastal Forest
TL;DR: In this article, the authors examined populations of the toad Rhinella ornata, a species endemic to Atlantic Coastal Forest in Brazil, and compared genetic diversity among small and medium forest fragments that were either isolated or connected to large forest areas by corridors.
Journal ArticleDOI
The challenge of maintaining Atlantic forest biodiversity: A multi-taxa conservation assessment of specialist and generalist species in an agro-forestry mosaic in southern Bahia
Renata Pardini,Deborah Faria,Gustavo M. Accacio,Rudi Ricardo Laps,Eduardo Mariano-Neto,Mateus Luís Barradas Paciencia,Marianna Dixo,Julio Baumgarten +7 more
TL;DR: In this paper, a multi-taxa survey was conducted to evaluate the potential for biodiversity maintenance in an Atlantic forest landscape that presented a favorable context from a theoretical perspective (high proportion of mature forest partly surrounded by structurally complex matrices).
Journal ArticleDOI
Ferns, frogs, lizards, birds and bats in forest fragments and shade cacao plantations in two contrasting landscapes in the Atlantic forest, Brazil
Deborah Faria,Mateus Luís Barradas Paciencia,Marianna Dixo,Rudi Ricardo Laps,Julio Baumgarten +4 more
TL;DR: In the landscape with few small forest fragments interspersed into extensive areas of shade cacao plantations, the beta diversity of birds was higher than in the more forested landscape, suggesting that forest specialist species that rarely ventured into cabrucas were randomly lost from the fragments.
