Abstract Since 2005, the Brazilian Ornithological Records Committee (CBRO) has published
updated checklists of Brazilian birds almost every year. Herein, we present a completely …

Mixed‐species animal groups (MSGs) are widely acknowledged to increase predator
avoidance and foraging efficiency, among other benefits, and thereby increase participants' …

Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …

The gut microbiota of vertebrates are essential to host health. Most non-model vertebrates,
however, lack even a basic description of natural gut microbiota biodiversity. Here, we …

Mixed-species flocks of foraging birds have been documented from terrestrial habitats all
over the world and are thought to form for either improved feeding efficiency or better …

Visual signals are shaped by variation in the signaling environment through a process
termed sensory drive, sometimes leading to speciation. However, the evidence for sensory …

Avian insectivores of the tropical rainforest understory (“understory insectivores”) are
common, diverse, and often sensitive to disturbance of tropical forest, making them useful as …

Methods that assess patterns of phylogenetic relatedness, as well as character distribution
and evolution, allow one to infer the ecological processes involved in community assembly …

Explaining the origins and evolution of Amazonian biodiversity continues to be an
outstanding question in evolutionary biology. A plethora of mechanisms for promoting …
