After 3–4 million years and a globe-spanning series of vicariant and dispersal events, trumpetfish lineages have come back into contact in the southwest Atlantic and appear to be merging, a ring species phenomenon that may occur in a broad array of marine organisms, with clear implications for the production and maintenance of biodiversity in marine ecosystems.
Shallow mtDNA coalescence in Atlantic pygmy angelfishes (genus Centropyge) indicates a recent invasion from the Indian Ocean.
The mtDNA genealogy indicates a colonization pathway from the Indian Ocean directly to the West Atlantic, followed by at least two waves of dispersal to the Mid-Atlantic Ridge.
The Monotypic Sardines, Sardina and Sardinops: Their Taxonomy, Distribution, Stock Structure, and Zoogeography
Analysis of biochemical genetics information, fossil evidence, and present and paleo-climatic conditions suggests that Sardinops did not achieve its present distribution until the Pleistocene and that westward exchange of sardines via the northern and southern west wind drift regions is possible with present climatic conditions.

If mismatch distributions and BSPs largely reflect demographic history, the widespread signature of population expansion in vertebrate, invertebrate, and plant populations appears to reflect responses to postglacial climate warming.
Mixed‐stock analysis reveals the migrations of juvenile hawksbill turtles (Eretmochelys imbricata) in the Caribbean Sea
The mixed‐stock analysis demonstrates that harvests in feeding habitats will impact nesting colonies throughout the region, with the greatest detriment to nearby nesting populations.
Recording Devices on Free‐Ranging Marine Animals: Does Measurement Affect Foraging Performance?
Observations of foraging patterns are essential to understanding the energetic ecology of marine animals. However, direct observations are not often feasible in the field because most foraging takes…
PHYLOGEOGRAPHY OF THE SARDINES (SARDINOPS SPP.): ASSESSING BIOGEOGRAPHIC MODELS AND POPULATION HISTORIES IN TEMPERATE UPWELLING ZONES
Sardines (Sardinops spp.) occupy temperate upwelling zones in the coastal regions of the Indian and Pacific Oceans, including locations in Japan, California, Chile, Australia, and South Africa. East…

Characterizing diversity in salmon from the Pacific Northwest
Information developed during recently completed evaluations of the status of seven species of anadromous Pacific salmonids (Oncorhynchus spp.) in the Pacific Northwest was used to characterize…
