A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Benthic Microalgae Respond More Strongly to Warming and Salinity Than Zooplankton

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
The effects of multiple simultaneous stressors on different trophic levels are poorly known. Warming changed the composition of both benthic diatom and zooplankton communities, but the interaction of warming and decreasing salinity affected only benthic diatoms. ABSTRACT The effects of elevated temperature are pronounced in high latitudes where warming
