Lifespans of animals inform us about generation length, underpinning assessments of extinction risk and models for fishery harvest strategies. Uncertainty and contention endure about the lifespans of coral reef echinoderms, especially soft-bodied sea cucumbers. We used a photographic mark–recapture study at Lizard Island, Australia, to validate longevity, growth and displacement in the large sea cucumber Bohadschia argus . Thi...

Highway construction causes environmental stressors in streams such as sedimentation, habitat fragmentation, and altered hydrology, yet their impacts on community dynamics beyond simple diversity metrics remain poorly understood. We assessed the effects of highway construction on multiple dimensions of stream fish community dynamics (stability, species turnover, and synchrony) using a 6-year Before-After design at four stream...

Vegetation surveys provide key information for evaluating functions within and across estuaries. However, survey methods and analyses are often highly variable, site-specific, and driven by monitoring program goals and objectives, making regional comparisons that include multiple programs difficult. This study compared multiple transect- and quadrat-based vegetation monitoring methods within eight southern California estuaries...
