Acute toxicity of titanium dioxide nanoparticles in Daphnia magna and Pontogammarus maeoticus [PDF]

open access: yesJournal of Advances in Environmental Health Research, 2015
Titanium dioxide nanoparticles (nTiO2) are the world's second most widely consumed nanomaterial and large quantities of this material enters the aquatic ecosystem annually.

Caught Between Macrophytes and Human Impact: Zooplankton Facing Multiple Stressors in Tropical Waters

open access: yesAustral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT Tropical freshwater systems host diverse and functionally important zooplankton communities that are increasingly threatened by multiple stressors. Here, we assessed how land‐use disturbance, local environmental conditions and macrophyte structure influence zooplankton richness, abundance and composition in Amazonian ponds and streams.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1701-1713, September 2026.
Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

Amino Acids in the Natural Food Web of Global Fishponds: Way Forward for Precision Protein Feeding in Pond Cyprinid Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Natural food webs in freshwater pond ecosystems provide an important nutritional foundation for cyprinid aquaculture, yet information on their protein and amino acid composition remains fragmented. This review synthesized published data from 30 studies (1950–2026) reporting protein and indispensable amino acid (IAA) composition of freshwater ...

Distribution and abundance of Cladocera, Copepoda and impacts of alien species in the southwestern Caspian Sea during 1996-2014 [PDF]

open access: yesبوم‌شناسی آبزیان, 2019
The Caspian Sea ecosystem has been suffered from many problems since 1980s. Owing to the significance of zooplankton communities in marine ecosystems, the state of the fluctuations of Copepoda and Cladocera species and their relationship with Ctenophora ...

Response of the Diet Composition of Carassius auratus to Water Quality in Dianchi Lake, China

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Understanding the relationship between the diet composition of fish and water quality is significant for assessing fish responses to habitat changes. However, due to the complexity and diversity of both fish feeding and water quality, the relationship between the diet composition of fish and water quality is not fully understood to date.

Disentangling population strategies of two cladocerans adapted to different ultraviolet regimes

open access: yesEcology and Evolution, 2018
Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life‐history traits of ...

Beyond the Cascade Dams: Scale‐Dependent Effects on Zooplankton Stability in River Ecosystems

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Cascade dams alter river zooplankton community stability, but how regulating factors act across local and regional spatial scales is poorly understood. Using field sampling and structural equation modeling, we revealed divergent scale‐dependent responses of zooplankton stability to dams—local stability depended on biodiversity, while regional stability

Desiccation to DNA: Bulk DNA Metabarcoding of Macroinvertebrate Egg Banks via Sugar‐Flotation Enhances Biodiversity Surveys of Dry Salt Lakes

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Ephemeral salt lakes in arid Australia contain hidden macroinvertebrate biodiversity in sediment egg banks, but traditional artificial rehydration surveys may miss taxa with specific or poorly understood hatching requirements. This study found that sugar‐flotation followed by DNA metabarcoding greatly improved detection of resting‐stage taxa compared ...
