Abstract:
... Interest in functional diversity has grown in recent years, indicating that knowledge on ecosystem functions gain importance. However, the incongruent use of terms may lead to misunderstandings and incomparable results. We aimed to review terms used in functional diversity among the Brazilian scientific community to identify if there is a lack of consensus in the terminology used. We applied onlin ...
Passeriformes; deforestation; functional diversity; habitats; highlands; landscapes; species dispersal; topography; tropical forests; Brazil
Abstract:
... The theory behind metacommunity was recently reframed to incorporate the concepts of community ecology. Here we investigate how slight topographic variations might locally create habitat heterogeneity and a system of interchanging bird species (i.e., a metacommunity) in a continuous tropical forest. We studied the distribution of birds in a large and protected Neotropical Forest in southwestern Br ...

Abstract:
... Hydroelectric dams are among the main cause of anthropogenic impacts in tropical environments. Damming interrupts the continuity of the river and produces the flooding of adjacent terrestrial ecosystems. Despite the negative effects on terrestrial and aquatic biodiversity, studies of the impacts of hydroelectric dams on species and community functional responses to flooding are scarce. Here, we ev ...
... Climate change may impose extreme conditions which potentially affect species’ distributions, leading to spatio-temporal variation in biodiversity and ecosystem services patterns. Here we compared current climate conditions to future climate scenarios projected to 2050 to assess potential changes in the spatio-temporal patterns of the taxonomic and functional diversities of the woody species of th ...

Abstract:
... We still lack practical guidelines for diversifying cropping systems that consider both yield and regulating functions of agroecosystems. Recent studies have suggested that maximizing functional diversity (FD, the distribution of species with different functional traits in the niche space) may lead to agroecosystems with greater multifunctionality due to niche complementarity. Therefore, scientist ...
Eragrostis plana; dry matter content; functional diversity; grasslands; herbicides; invasive species; leaves; palatability; species diversity; Brazil
Abstract:
... QUESTIONS: Eragrostis plana is the most invasive species in grasslands of southern Brazil. We ask how it affects the functional structure of communities considering leaf traits related to forage palatability for grazers. As consensus is lacking about whether to include or omit the invasive species in the analysis, we propose a method for partitioning functional diversity (FD) and community‐weighte ...
... We evaluated temporal trends in zooplankton functional diversity (functional richness—FRic, evenness—FEve divergence—FDiv, and Community-Weighted Means—CWM) in 12 habitats of the Upper Paraná River floodplain (Brazil) over 16 years (2000–2016) and their relationships with environmental predictors (chlorophyll-a, water depth, and turbidity). We hypothesized that different environmental drivers affe ...

Abstract:
... QUESTIONS: Grasslands in subtropical Brazil are known as potentially fire‐prone ecosystems. Aiming to better understand the effects of fire on biodiversity, we addressed the following questions: does fire benefit all alpha and beta components of taxonomic and functional diversity in grasslands; which functional groups are affected; does diversity foster recovery of above‐ground biomass after fire? ...
... Several studies attempt to understand the mechanisms underlying compensatory and synchronous dynamics, and how these mechanisms relate to community stability. For this purpose, the use of functional traits, in theory, would allow for a direct evaluation of whether functional similarity generates compensatory dynamics or interspecific synchrony. Likewise, a trait-based approach is also needed to ev ...
