Demography and dynamics of giant kelp cohorts across four decades: Lessons for conservation and resilience planning

Ecological Applications, Volume 36, Issue 1, January 2026.
Abstract Kelp forests throughout many temperate zones are in decline due to various human stressors, chiefly marine warming. Conservation measures including restoration are presently of great interest and focus on both historical and novel methodologies.

Physiological and Epigenetic Responses of the Long‐Spined Sea Urchin Diadema antillarum Across a Spatiotemporal Gradient

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Following catastrophic population declines in the 1980s and 2022, the keystone herbivore Diadema antillarum has become a focal species for Caribbean‐wide restoration initiatives. In the present work, we combined an 11‐month field survey across four reefs in the island of Culebra, Puerto Rico, with a reciprocal transplant experiment to evaluate ...

Food limitation erodes the thermal tolerance of larvae in an ecologically influential marine herbivore

Ecology, Volume 107, Issue 1, January 2026.
Abstract Biologists often use organismal thermal tolerance to help explain or forecast responses of populations to climate change. Yet many studies quantify thermal tolerance under isolated laboratory conditions despite extreme events, such as heatwaves, often coinciding with other stressors such as nutrient or food limitation.
