Stage‐Specific Indicators of Northern Yellowtail Rockfish (Sebastes flavidus) Recruitment in the California Current Ecosystem

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...
