The ability of feathers to perform many functions either simultaneously or at different times
throughout the year or life of a bird is integral to the evolutionary history of birds. Many …

Inferring evolutionary relationships between recently diverged taxa is still challenging,
especially taking into account the likely occurrence of incomplete lineage sorting and/or …

Changes in this supplement include the following:(1) seven species (Alopochen aegyptiaca,
Phoebastria irrorata, Pterodroma madeira, Syrigma sibilatrix, Patagioenas goodsoni …

Abstract Models of adaptive radiation were originally developed to explain the early, rapid
appearance of distinct modes of life within diversifying clades. Phylogenetic tests of this …

Tetraodontiformes (pufferfishes and kin) is a taxonomically and structurally diverse, widely‐
distributed clade of acanthomorphs, whose members often serve as models for genomics …

We report on the breeding biology of the White-throated Woodcreeper (**phocolaptes
albicollis), a species endemic to the Atlantic forest of South America, based on 16 nesting …

Results of a comprehensive molecular phylogeny of the family Thamnophilidae were
consistent with earlier findings that almost all obligate army-ant-followers of the family form a …

Endotherms at high altitude face the combined challenges of cold and hypoxia. Cold
increases thermoregulatory costs, and hypoxia may limit both thermogenesis and aerobic …

Phenotypic traits are expected to be more similar among closely related species than among
species that diverged long ago (all else being equal). This pattern, known as phylogenetic …

Phylogeographic analyses have hypothesized that Sclerurus (Furnariidae) populations of
the rufous-throated clade (S. rufigularis and S. mexicanus sensu lato) have a long history of …
