The Extinction Risk–Range Change Relationship: Evidence From the Fossil Record

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Climate change is a major driver for the wave of species extinctions predicted for this century. Extinction risk assessments are often estimated from climate‐driven reductions in the geographic ranges of species. However, the empirical relationship between extinction risk and range change remains unclear because few extinctions are ...

Hard Rock Buffet: Chemosynthetic Carbon Use and Environmental Trophic Structuring of Carbonate‐Associated Macrofauna at Southern California Methane Seeps

open access: yesMarine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Diverse invertebrate communities inhabiting carbonate rocks at methane seeps may rely on a mix of local chemosynthetic production and sinking photosynthetic organic matter, with relative importance shaped by environmental conditions. We investigate the contribution of chemosynthetic carbon to macrofaunal diets at six Southern California ...

Examining Marine Assemblages Across an Inverse Salinity Gradient

open access: yesMolecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia.
