Light and temperature as triggers for surface filamentous green algal blooms in shallow freshwater systems

Limnology and Oceanography, Volume 70, Issue S2, Page S155-S169, December 2025.
Abstract Blooms of filamentous green algae (FGA) form dense mats at the surface of shallow freshwaters and have multiple negative impacts on aquatic ecosystem functions, services, and aesthetics. Although nutrient enrichment in freshwaters is a primary driver of excessive FGA growth, much less is known about other abiotic factors controlling bloom ...

Acute and long‐term warming effects on the functional response and reproductive efficiency of marine copepods

Limnology and Oceanography, Volume 70, Issue 12, Page 3898-3911, December 2025.
Abstract The impact of climate change stressors on marine copepods, key organisms at the base of ocean food webs, remains understudied. This study examined how warming affects their functional and numerical responses, critical life history traits linked to fitness.

Environmental DNA as a tool for hydropower impact assessments: current status, special considerations, and future integration

Biological Reviews, Volume 100, Issue 6, Page 2584-2607, December 2025.
ABSTRACT Globally there is an urgent need to find sustainable solutions to balance energy production with the protection of vulnerable species and conservation of biodiversity. This is particularly critical for freshwater ecosystems, habitats, and species that may be impacted by hydropower development and operations needed to meet energy grid demands ...

Seasonal Breeding and Morphological Variation Across Age and Sex in the Antioquia Brushfinch (Atlapetes blancae)

Ecology and Evolution, Volume 15, Issue 11, November 2025.
The reproductive season of A. blancae most likely spans from February through August with peak reproductive activity during May, and is highly correlated to day length, and precipitation during the first rainy season of the year, furthermore, it is also highly correlated with the reproductive activity of many other species in the genus Atlapetes ...

Income and capital breeding—Calanus reproduction in a subarctic fjord

Limnology and Oceanography, Volume 70, Issue 11, Page 3544-3551, November 2025.
Abstract Copepods of the genus Calanus are key species in the energy transfer from primary producers to higher trophic levels in Arctic and sub‐Arctic seas. The timing of reproduction can differ between species, depending on whether they rely on external energy sources to initiate reproduction (income breeders) or use internal energy sources (capital ...

Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

Limnology and Oceanography, Volume 70, Issue 11, Page 3355-3369, November 2025.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...

Planktonic larval stages—an adaptation to lower predation rates in the pelagic environment?

Limnology and Oceanography, Volume 70, Issue 11, Page 3417-3430, November 2025.
Abstract A majority of marine benthic macroinvertebrate and fish species have planktonic larval stages that disperse in the water column from days to months. However, the adaptive significance of pelagic larvae, and whether predation is higher in the pelagic or the benthic environment, is still debated, partly due to a lack of studies assessing larval ...

Hydropower Effluent as a Marine Pollutant; Impacts of River Regulation on Estuarine and Coastal Ecology

River Research and Applications, Volume 41, Issue 9, Page 1789-1802, November 2025.
ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.
