Current Protections and Future Threats to Say's Spiketail Habitat in the Southeastern USA

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Dragonflies and damselflies are important indicators of ecological integrity and environmental quality but remain underrepresented in conservation efforts, in part due to a lack of quantitative information regarding their habitat requirements. Species distribution models (SDMs) can facilitate conservation planning by allowing researchers to estimate ...

Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the tropical and the subtropical Atlantic representative of different water bodies (NE Brazil shelf,

From kelp forests to turf reefs: Patterns, drivers, and impacts to functional diversity

Ecology, Volume 107, Issue 5, May 2026.
Abstract Kelp forests are declining in many regions due to ocean warming, predator loss, and other anthropogenic stressors. In areas of rapid ocean warming, including the southern Gulf of Maine, these ecosystems have transitioned to a novel state dominated by low‐lying mats of turf algae.

ON THE HYDROGRAPHY OF THE RIVER CLYDE

Coastal Engineering Proceedings, 1966
The River Clyde is one of the major industrial rivers of Scotland and the shipbuilding on the banks of its estuary has been famous for centuries. With the increase in the size of the ships being constructed and using the Clyde as a port, steps must be taken to ensure that the Clyde maintains its relative position.
