Abstract. Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically r...

Functional traits can determine pairwise species interactions, such as those between plants and pollinators. However, the effects of biogeography and evolutionary history on trait‐matching and trait‐mediated resource specialization remain poorly understood. We compiled a database of 93 mutualistic hummingbird‐plant networks (including 181 hummingbi...
Article
The degree of habitat specificity determines the distinctive ways that birds respond to land-use and climate change. Information on habitat-use, movement potential and sensitivity to human disturbance can promote reliable predictions on species response to spatial and temporal global changes. Here, we made an extensive review about habitat-use of 5...

Wildfire is a natural process in Brazilian savannas, but human activities alter fire regimes and threaten biodiversity. In this study, weused an ecoacoustics approach to assess fauna responses and recovery after wildfire in a Brazilian savanna. Six passive acoustic monitoring devices were used to record soundscapes before and after a wildfire a at...

Climate change affects biodiversity in various ways but not linearly. Mountaintop species and ecosystems are expected to experience the strongest impacts of climate change. Lower tolerances to changes in habitat and decreased available surface area with increasing elevation should lead to smaller ranges and even extinctions of endemic species livin...
Article
Among the 44 known species of Scytalopus, only 25 have some type of reproductive information available. Here we present the first description of the nesting site, nest, and eggs of the Rock Tapaculo (Scytalopus petrophilus). The nest was registered inside a ferruginous cave located in the Serra do Gandarela National Park, Minas Gerais, Brazil. The...
Article
We assessed the evolutionary histories of two hummingbirds, Augastes scutatus and A. lumachella, endemic to the highlands of the Espinhaço Range in Brazil. These hummingbirds are considered relictual taxa with phylogenetic affinities to members of the genus Schistes from the Andean region. We reconstructed phylogenetic relationships of Augastes thr...

Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap and species abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the mechanisms that drive the geographical...
Article
Cipo Canastero Asthenes luizae is a relict ovenbird restricted to rocky outcrops at high elevations within the campo rupestre vegetation of the Espinhaço Range in the state of Minas Gerais, south-eastern Brazil. This poorly known species is considered ‘Near Threatened’, but recent studies have suggested that it should be listed under a higher categ...
Article
The Cipo Cinclodes Cinclodes espinhacensis is a recently described furnariid endemic to the campos rupestres of Serra do Cipó, southern Espinhaço Range, southeastern Brazil. It is an “Endangered” species and its natural history is poorly known. We studied the Cipo Cinclodes breeding biology at Serra do Breu, where we found six nests on rock outcrop...

Traditional conservation techniques for mapping highly biodiverse areas assume there to be satisfactory knowledge about the geographic distribution of biodiversity. There are, however, large gaps in biological sampling and hence knowledge shortfalls. This problem is even more pronounced in the tropics. Indeed, the use of only a few taxonomic groups...
Article
Full-text available
Abundant pollinators are often more generalised than rare pollinators. This could be because abundant species have more chance encounters with potential interaction partners. On the other hand, generalised species could have a competitive advantage over specialists, leading to higher abundance. Determining the direction of the abundance–generalisat...
Data
Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morpho- logical variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological d...

The birds of most elevated parts of hills in western Pan-tanal are little known, mentioned only in general compilations. We report on the avifauna from western Pantanal wetland. It was recorded a total of 412 bird species, of which 24% are regularly migratory (16 Northern species and 84 Southern species). At least 7 species are in the lists of exti...

Abundant pollinators are often more generalised than rare pollinators. This could be because abundance drives generalisation: neutral effects suggest that more abundant species will be more generalised simply because they have more chance encounters with potential interaction partners. On the other hand, generalisation could drive abundance, as gen...

Cerrado dry forest enclaves have been treated as an endemic bird area. In the last years, some avifaunal surveys have been conducted in dry forests on the left bank of the São Francisco River, eastern Brazil. Nevertheless, there is a gap of detailed ornithological surveys in the Cerrado dry forest enclaves on the right bank of this river. Here, we...

Although Brazil is a megadiverse country and thus a conservation priority, no study has yet quantified conservation gaps in the Brazilian protected areas (PAs) using extensive empirical data. Here, we evaluate the degree of biodiversity protection and knowledge within all the Brazilian PAs through a gap analysis of vertebrate, arthropod and angiosp...

Amazonian rivers are usually suggested as dispersal barriers, limiting biogeographic units. This is evident in a widely accepted Areas of Endemism (AoEs) hypothesis proposed for Amazonian birds. We empirically test this hypothesis based on quantitative analyses of species distribution. We compiled a database of bird species and subspecies distribut...

Human-caused alterations to the environment are important causes of the loss of bird biodiversity globally. Collisions with windows are the second leading human cause of mortality for birds, and it is estimated that 100 million to one billion birds die due to window collisions annually in the US alone. However, in Brazil there have been no systemat...

An animal’s vulnerability to predators can be influenced by its behavior, morphology, body size, coloration, habitat preferences, and palatability. We tested whether the coloration of Bokermannohyla saxicola and Scinax machadoi tadpoles affects their survival when exposed to local visually oriented predators at a site in southeastern Brazil. We tes...
