A dynamic framework for marine radioactivity baselines: Climate-driven variability of 137Cs in the Pacific Ocean

Radiocesium-137 ( 137 Cs) is a useful tracer of ocean circulation because of its long physical half-life and relatively conservative behavior in seawater. We investigated variability in Pacific 137 Cs concentrations and apparent half-lives using observational datasets and numeric...

Social system and spatial behavior drive interspecific differences in foraging intensity and plant-level damage in sympatric ungulates

Foraging behavior in ungulates affects not only their own fitness but also the fitness and morphology of the plants they consume. While intraspecific variation in ungulate foraging behavior has been extensively studied, interspecific differences—particularly those associated with...
