Comparing Sediment and Water eDNA Metabarcoding for Monitoring Aquatic Biodiversity in a Plateau Lake

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Using multi‐locus eDNA metabarcoding of sediment and water samples collected from a plateau lake, this study systematically compared taxonomic diversity and community composition between the two sample types across the tree of life from archaea to mammals.

Food web complexity alters phytoplankton persistence and resilience to nutrient pulses in experimental ecosystems

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract In aquatic ecosystems, greater food web complexity is theorized to increase persistence and resilience of primary production to pulse disturbances, yet experimental evidence is limited. We simulated two storm‐induced pulse disturbances by adding nutrients (~ 3%–5% increase in ambient concentrations) to three ponds with low, intermediate, and ...

Under‐Ice Ecological and Biogeochemical Dynamics at the Onset of Spring Thaw in Four Arsenic‐Contaminated Subarctic Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Interactions between aquatic organisms and contaminants in under‐ice lake environments are poorly characterized relative to ice‐free seasons. Here, we compared under‐ice arsenic biogeochemical processes and plankton community composition in four subarctic lakes spanning an arsenic contamination gradient.

Nutritional effect of three microalgae and one cyanobacteria on the culture of the rotifer Brachionus plicatilis Müller: 1786

Ciencias Marinas, 1996
Three microalgae and one dehydrated cyanobacteria were tested to determine the best concen­tration and the best food for the culture of a local strain of the rotifer Brachionus plicatilis type L. The observations were: density of rotifers, fecundity and

Bridging Ecology and Geosciences in Riverscapes: Implications for Process‐Based Restoration

Ecological Research, Volume 41, Issue 1, January 2026.
In this paper, we synthesize studies that integrally examine geological and ecological processes across different scales and components of riverscapes, including geohydrological processes. Finally, we identify both scientific and practical challenges that must be addressed to bridge the gap between basic‐science implications and their implementation in

Elevation‐mediated cold water refugia in subalpine lakes

Conservation Science and Practice, Volume 8, Issue 1, January 2026.
High‐elevation ecosystems may serve as climate change refugia by preserving colder conditions among rising regional temperatures, but this phenomenon is not well‐described in lakes compared to other systems. In subalpine lakes in the northern Appalachian Mountains, ice persisted longer into the year and water temperatures reached a lower summer maximum

Temporal Beta Diversity of Local Zooplankton Communities in Small Reservoirs is Associated With Hydrological Seasonality

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT The variation in local community structure over time—temporal beta diversity—is likely to depend on drivers similar to those used to explain spatial beta diversity. For example, in parallel with the expected relationship between geographic distance and spatial beta diversity, the longer the time between two sampling campaigns, the higher the ...
