Do short-term, reduced-volume methods accurately reflect chronic toxic effects in the cladoceran Ceriodaphnia dubia? A study with the reference toxicant hexavalent chromium

open access: yesFrontiers in Environmental Science, 2023
Cladocerans are frequently used as test organisms in aquatic toxicology studies. For practical reasons (bioethical and economic), efforts are currently made in search of alternative animal models and in defining short-lasting test methods that will allow

Nanoplastic Exposure Impairs Host Fitness and Parasite Transmission With Transgenerational Maternal Reproductive Costs in the Daphnia‐Fungal Parasite System

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Polystyrene nanoplastics (50 nm) severely reduced the fitness of Daphnia magna infected with the fungal parasite Australozyma monospora, halving parental survival and suppressing reproduction, and they lowered parasite maturation indirectly by killing hosts before transmission rather than by limiting within‐host infection.

First complete mitochondrial genome from family Moinidae, Moina macrocopa (Straus, 1820) (Cladocera; Moinidae)

open access: yesMitochondrial DNA. Part B. Resources, 2022
We sequenced and annotated the complete mitochondrial genome for the freshwater water flea Moina macrocopa (Straus, 1820). This is the first mitogenome for the family Moinidae. The complete mitogenome of M.

Effects of Reduced Precipitation and Water Level Variability on Phytoplankton Dynamics and Thermal Structure in a Large Tropical Reservoir

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Drought is one of the most severe and complex natural hazards causing changes in water balance and impeding crucial water‐dependent ecosystem services. Over the last 25 years, multiple severe droughts linked to El Niño events have affected the Zambian and Zimbabwean regions.

Eco‐Evolutionary Feedback to a Pesticide Worsens the Impact of a Pesticide Switch in a Pivotal Freshwater Non‐Target Species

open access: yesEcology Letters, Volume 29, Issue 10, October 2026.
Selection under the insecticide chlorpyrifos strongly affected the genetic makeup of non‐target Daphnia magna populations and increased tolerance of chlorpyrifos‐selected populations to chlorpyrifos and malathion (same mode of action as chlorpyrifos) but reduced performance when exposed to deltamethrin (different mode of action from chlorpyrifos).

Gems of the Middle‐East: Unravelling the Biodiversity of Monogonont Rotifers in Temporary and Semi‐Perennial Freshwater Habitats Across Israel

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT In temporary waterbodies such as ponds, pools and small lakes, the diversity of smaller invertebrates, such as rotifers, remains understudied, despite their ecological importance as prey and decomposers of organic matter. Especially in regions such as Israel, where natural lakes are scarce, temporary waterbodies become even more important as ...
