Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

Fisheries Oceanography, Volume 35, Issue 4, Page 545-564, July 2026.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

Paleolimnológiai vizsgálatok a Tiszadobi-holtmederben szubfosszilis Cladocera maradványok által [PDF]

, 2016
Munkálataim során a Tiszadobi Holt-Tiszából vett üledékmintákat vizsgáltam aszerint, hogy a vízgyűjtő területen található makrovegetációk mennyire befolyásolják előfordulásuk szerint az ott található Cladocera fajokat.

Impacts of Land Use and Flood Regime on Zooplankton Egg Banks in a Large River Floodplain

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Zooplankton egg banks are crucial in rebuilding zooplankton populations in temporary water bodies when favourable conditions return after dry periods. However, their abundance, viability, and hatching success depend on many factors, with changes in land use and flooding regimes being potentially crucial drivers.

Diverging Effects of Elevation on Species Richness of Freshwater Organisms: A Global Meta‐Analysis

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT A primary ecological challenge is to disentangle how abiotic factors affect species richness using measured environmental variables in addition to broad proxies such as elevation. Considering direct ecogeographical gradients, such as climate harshness, it is therefore essential to understand whether these underlying abiotic factors might ...

Sezonska varijabilnost i diverzitet cladocera (crustacea) u lagunama za prirodno prečišćavanje otpadnih voda iz domaćinstava [PDF]

, 2015
Cladocera predstavljaju najznačajniju komponentu zajednice zooplanktona u većini stajaćih slatkovodnih ekosistema. Kao filtratori, hrane se algama, bakterijama, protozoama i organskim česticama, koje obiluju u netretiranim otpadnim vodama iz domaćinstava.

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, Volume 109, Issue 1, Page 384-399, July 2026.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Cladocera in ponds of the Varanger Peninsula [PDF]

, 1988
Up to now 19 species of Cladocera have been found in ponds of the Varanger Peninsula (Eastern Finnmark, Norway), which are presented here. A comparison with other regions in the northern Holarctic shows, that the limits of distribution of Cladocera ...

Fungi Associated With Freshwater Zooplankton Are Taxon‐Specific, Temporally Dynamic and Reflect Allochthonous Inputs

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT The associations between microbes and planktonic invertebrates in freshwater ecosystems are considered key ecological interactions. However, our understanding of the structure, taxonomic specificity, and environmental drivers of zooplankton microbiomes remains poor.
