Maintaining genetic connectivity is a central requirement for the long-term persistence of wide-ranging wildlife populations in increasingly human-modified landscapes. Population genetic approaches provide valuable tools for evaluating connectivity patterns and identifying early signs of genetic isolation. However, robust supraregional comparisons are often limited by differences in sampling design, marker systems, and analyti...

In this laboratory study, we monitored the buildup of biomass and concomitant shift in seawater carbonate chemistry over the course of a Trichodesmium bloom under different phosphorus (P) availability. During exponential growth, dissolved inorganic carbon (DIC) decreased, while pH increased until maximum cell densities were reached. Once P became depleted, DIC decreased even further and total alkalinity (TA) dropped, accompani...
