A new tool to quantify biodiversity change under landscape transformation

Identifying how species richness or diversity changes with different proportions of natural and anthropized environments in the landscape is important for landscape management for conservation. Here, we propose a new method to assess biodiversity changes in landscapes with varying proportions of habitat types. The algorithm is based on the resampling of individuals recorded in different habitats considering bot...

The relative importance of forest cover and patch-level drivers for phyllostomi...

Context Analyze the multiple dimensions of biodiversity under a local and landscape lens in natural habitats, such as Amazonian savannas, is fundamental for the conservation of species and ecosystems. Objectives We aim to explore how landscape forest cover and patch-level variables affect the patterns of species abundance, functional traits, and taxonomic, functional and phylogenetic α-diversity of Phyllostomid...

The Fate of an Amazonian Savanna: Government Land-Use Planning Endangers Sustai...

Biodiversity, threats and conservation challenges in the Cerrado of Amapá, an A...

An Amazonian savanna in northern Brazil known as the Cerrado of Amapá is under imminent threat from poor land-use planning, the expansion of large-scale agriculture and other anthropogenic pressures. These savannas house a rich and unique flora and fauna, including endemic plants and animals. However, the area remains under-sampled for most taxa, and better sampling may uncover new species. We estimate that onl...

Deforestation control in the Brazilian Amazon: A conservation struggle being lo...

Despite efforts to reduce deforestation in the Brazilian Amazon, there has been an up-turn in clearing rates since 2012. These increases are in part due to failures in deforestation control. Soybean planters, cattle ranchers, and timber merchants find ways to circumvent agreements and legislation. Here we explain some of the key problems with the implementation of the principal agreements and Brazilian laws tha...

Phenology of the multi-use tree species Carapa guianensis in a floodplain fores...

Carapa guianensis is a multi-use tree species that is used for the production of timber and non-timber forest products (NTFPs) that are used and sold by rural Amazonian populations. Here we aimed to evaluate the phenophases of C. guianensis in várzea forest and relate them to climatic seasonality. Phenophases of flowering (flower buds and open flowers), fruiting (unripe and ripe fruits), and leaf flush and leaf...

Drivers of primate richness and occurrence in a naturally patchy landscape in t...

We assessed the spatial extent at which the species-landscape relationship is strongest (i.e. the scale of effect—SE) on primate occurrence (Alouatta belzebul, Saguinus midas, Saimiri sciureus, and Sapajus apella and Cebus olivaceus, the last two considered together in the analysis) and species richness and evaluated which landscape, patch, and human variables influence primate distribution in a savanna ecosyst...
