Evaluating Causal Links Between Chlorophyll a and Environmental Data in the Illinois River (USA)

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Chlorophyll a is widely used as a proxy for algal abundance due to its universality among algae and the practicality of measuring it with in situ sensors. In this study, we analyzed high‐frequency chlorophyll a and water quality data from the Illinois River to assess relationships between algal abundance and environmental drivers using both statistical

Diverging Food Web Functioning Around Southampton Island, Nunavut: The Influence of Primary Production Supply and Bathymetry

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

Differences in Wetland Efficiency Affect Future Lake Water Quality

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Wetlands are often constructed to counteract eutrophication or brownification of downstream waters, although our understanding of their differences in efficiency and effects is still scarce. Therefore, we here used the upper and lower 95% confidence limits of the average retention capacity of 11 wetlands to represent efficient and inefficient ...

Hypolimnetic anoxia in oligotrophic lakes and its effects on nutrient supply and phytoplankton communities

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Low concentrations of dissolved oxygen (DO) in hypolimnetic waters are becoming more common and could affect nutrient supplies available to phytoplankton communities in meso‐ and eutrophic lakes. We examined the connections among hypolimnetic DO, nutrient concentrations, and phytoplankton communities in 26 oligotrophic lakes in the Kawartha ...

Chronic and punctuated changes in subtropical reef fish assemblages

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Understanding temporal changes in marine biodiversity is crucial for managing and conserving reef ecosystems in the face of global environmental shifts. Although biodiversity changes at global and regional scales often differ, the role of subtropical systems in these patterns has been relatively understudied until recently.
