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

Marine 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 ...

I.—Morphological Studies on the Echinoidea Holeotypoida and their Allies [PDF]
Geological Magazine, 1917 AMONG the Echinoids from the Limestone Lenticles of Shenley Hill (Leighton Buzzard), sent to me from the Sedgwick Museum, Cambridge (see Geol. Mag., Vol. LVIII, 1921, p. 57), one specimen of the many Pyriniform examples at once attracted attention by its preservation, relatively large size, and superficial resemblance to Holectypus.
