Freshwater Biology, Volume 70, Issue 10, October 2025.ABSTRACT Nutrient loading, aquatic invasive species, and climate warming have altered food web dynamics in the Great Lakes. Long‐term data are required to characterise the response of the lower food web to multiple environmental drivers and develop trophic indicators for future research and management efforts.

Mesozoic fossils (>145 Mya) suggest the antiquity of the subgenera of Daphniaand their coevolution with chaoborid predators [PDF]
, 2011 Background The timescale of the origins of Daphnia O. F. Mueller (Crustacea: Cladocera) remains controversial. The origin of the two main subgenera has been associated with the breakup of the supercontinent Pangaea.

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

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.ABSTRACT Artemia (brine shrimp) is a foundational live feed in global aquaculture, renowned for its adaptability, ease of production, and favorable nutritional profile. However, in its natural state, Artemia contains suboptimal levels of highly unsaturated fatty acids (HUFAs), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA ...

Three's a crowd: The relationship among endoparasites, an epibiont and their Daphnia host
Oikos, Volume 2025, Issue 8, August 2025.In freshwater communities, organisms interact in a variety of ways, including predation, competition and parasitism. Parasites are ubiquitous, playing an important role in shaping freshwater communities. Endoparasites live within internal organs of their host, while ectoparasites, also known as epibionts, are confined to the external part of the host's

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