A new species of Chromis damselfish from the tropical western Atlantic (Teleostei, Pomacentridae) [PDF]
ZooKeys, 2020 Initially described in 1882, Chromis enchrysurus, the Yellowtail Reeffish, was redescribed in 1982 to account for an observed color morph that possesses a white tail instead of a yellow one, but morphological and geographic boundaries between the two ...

Intraspecific Phylogeography Across the Point Conception Biogeographic Boundary [PDF]
Evolution, 1998 Recent studies of intraspecific phylogeography have suggested that the geographic location of genetic discontinuities, or phylogeographic breaks, may frequently coincide with biogeographic boundaries. The concordance is hypothesized to reflect similarity in the processes governing species boundaries and intraspecific lineage boundaries.

Cranial and mandibular shape variation in the genus Carollia (Mammalia: Chiroptera) from Colombia: biogeographic patterns and morphological modularity [PDF]
PeerJ, 2015 Neotropical bats of the genus Carollia are widely studied due to their abundance, distribution and relevance for ecosystems. However, the ecomorphological boundaries of these species are poorly differentiated, and consequently correspondence between ...

A COMPARATIVE STUDY OF ASYMMETRIC MIGRATION EVENTS ACROSS A MARINE BIOGEOGRAPHIC BOUNDARY [PDF]
Evolution, 2001 In many nonclonal, benthic marine species, geographic distribution is mediated by the dispersal of their larvae. The dispersal and recruitment of marine larvae may be limited by temperature gradients that can affect mortality or by ocean currents that can directly affect the movements of pelagic larvae.
