Deforestation is a major threat globally, but especially in tropical regions because they are
biodiversity strongholds and carbon storehouses. Some studies have reported changes in …

Aim Spatial processes and environmental filtering are important factors sha** community
composition, but their effects are rarely tested across all aspects and components of beta …

Understanding the processes and mechanisms that shape the distribution patterns and
variations of biodiversity along spatial gradients continues to be a priority for ecological …

In this manuscript, we aimed to answer: 1) which environmental and spatial processes are
determinant for the patterns of co-occurrence of fish in Amazonian streams, and 2) which …

The evaluation of extinction risk has typically focused on individual species, although a shift
to a focus on ecosystem functioning would appear to be an urgent priority for conservation …

In the perspective for partitioning beta diversity proposed by Baselga (2010), species loss
was assumed to increase the nestedness component. As species loss is generally non …

Freshwater ecosystems are among the most threatened ecosystems on Earth. Effective
conservation strategies are essential to reverse this trend and should be based on sound …

Understanding the spatial structure of genetic diversity provides insights into a populations'
genetic status and enables assessment of its capacity to counteract the effects of genetic …

The expansion of agriculture in the southeast Amazon-Savanah transitional area has greatly
decreased forest cover and influenced stream structure and functioning. We assessed the …

In this study, we assessed the effects of multiple land uses and local habitat variables on the
composition of fish functional trophic groups (FTG's) and on the ecomorphological traits of …
