Abstract Sediment loading from land and turbidity in coastal waters has increased because of human activities in coastal catchments and through climate‐related increases in storm intensity and frequency. Here, we investigated changes in coastal seafloor biodiversity and ecosystem function across a suspended sediment concentration gradient in a New ...

Abstract Nitrous oxide (N2O) is an ozone‐depleting greenhouse gas that has a global warming potential nearly 300 times greater than carbon dioxide. Although the oceans contribute about 21% of atmospheric global N2O emissions, we know relatively little about N2O dynamics in nearshore systems. Here, we document the fourfold increase in the abundance of a

Sensitivity of Mediterranean amphipods and sea urchins to reference toxicants
Toxicity tests were performed in two amphipod species, Gammarus aequicauda and Microdeutopus gryllotalpa, and three sea urchin species, Arbacia lixula, Paracentrotus lividus and Sphaerechinus granularis.

Refuge trifecta: intertidal gastropods use pits to escape heat, wave action and predation
Refuges play a critical role in ecology and evolution. In hard intertidal shores, small pits attract benthic invertebrates such as gastropods, however, there exists little mechanistic understanding of the processes driving the active usage of these microhabitat features. We conducted a series of laboratory experiments to assess whether the marine snail
