Increasing data have supported the importance of divergence with gene flow (DGF) in the
generation of biological diversity. In such cases, lineage divergence occurs on a shorter …

The importance of geographic isolation in speciation has been debated since the 19th
century. Since the beginning of the 20th century, the consensus has been that most …

As in previous lists, orders, families, and genera are listed in conventional phylogenetic
sequence mostly following Hall (1981) but, in a departure from previous lists, species are …

Few mammalian species produce vocalizations that are as richly structured as bird songs,
and this greatly restricts the capacity for information transfer. Syntactically complex …

Patterns of geographic variation in communication systems can provide insight into the
processes that drive phenotypic evolution. Although work in birds, anurans, and insects …

While museum voucher specimens continue to be the standard for species identifications,
biodiversity data are increasingly represented by photographic records from camera traps …

Researchers have a natural tendency to classify biological systems into categories. For
example, organisms can be classified based on biome, ecosystem, taxon, phylogeny, niche …

Isolation calls produced by dependent young are a fundamental form of communication. For
species in which vocal signals remain important to adult communication, the function and …

Wolves, coyotes, and other canids are members of a diverse genus of top predators of
considerable conservation and management interest. Canid howls are long-range …

The chipmunks are a Holarctic group of ground squirrels currently allocated to the genus
Tamias within the tribe Marmotini (Rodentia: Sciuridae). Cranial, postcranial, and genital …
