Elevated carbon dioxide can boost freshwater zooplankton abundance, while warming may shift community composition, weakening phytoplankton control

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S273-S288, December 2025.
Abstract Zooplankton communities in ponds and lakes control phytoplankton growth and serve as a food source for higher trophic levels such as fish. Recent experiments have shown that several freshwater zooplankton species as well as the phytoplankton communities on which they feed can be variably affected by rising temperatures, reduced pH and higher ...

Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

open access: yes, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras

open access: yesWildlife Society Bulletin, Volume 49, Issue 3, September 2025.
We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Guide to the freshwater fauna of Ceylon (Sri Lanka). Supplement 4 [PDF]

open access: yes, 1974
In the present supplement, where records in the past have been few in a group, new records are given of localities both as regards species previously recorded from Sri Lanka and especially for new records. This gives the new records more standing and may

Impact of CO2‐Induced Aquatic Acidification on Environmental DNA and RNA Shedding and Persistence

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
We conducted mesocosm experiments to determine the shedding and decay rate constants of eDNA and eRNA in Pacific oysters (Crassostrea gigas) at various partial CO2 pressures in seawater. To our knowledge, this is the first study manipulating seawater pH using CO2.

Evaluating the Effectiveness of Forest‐to‐Bog Restoration on Carbon Sequestration, Water Chemistry, and Biodiversity in Irish and British Peatlands

open access: yesWIREs Climate Change, Volume 16, Issue 4, July/August 2025.
A forest‐to‐bog restoration site in Co. Fermanagh, N. Ireland, 4 years after clear‐felling, conifer removal, and cell bunding (surface bunds joined to form watertight cells to retain shallow water and minimize edge effects), shows accelerated Sphagnum growth—exemplifying restoring degraded peatland toward near‐natural conditions—that is, minimally ...

High taxonomic resolution as a determinant on finding new species and new records in the Río de La Plata basin: a case on Chydoridae (Crustacea: Branchiopoda: Cladocera)

open access: yesNauplius
Recent worldwide taxonomical research on Cladocera is discovering a number of new species but hardly in South America. The Río de La Plata is the second largest basin in the continent and the knowledge on cladocerans of the different sub-basins is uneven.
