What Drives the Changing Characteristics of Plankton in Floodplain Lakes: Season, Environmental Factors, or Lake Characteristics?

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
In this study, we conducted investigations and monitoring on lakes during the wet season and dry season. We studied the structure, taxonomic/functional diversity, community assembly, and niche differentiation of plankton communities, analyzed the biogeographical patterns of plankton communities, and explored the driving factors affecting plankton ...

Memaksimalkan Potensi Dormansi Pada Rotifer Brachionus Rotundiformius Melalui Mating Eksperimen [PDF]

open access: yes, 2010
The rotifer Brachionus sp is widely used in aquaculture as a live prey, but problem remain with less utilization. It is often difficult to synchronize rotifer production with larvae demand.

Developing a Fecal DNA Method With Blocking Primers to Determine Red Knots' (Calidris canutus) Diets Noninvasively

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
The blocking primer suppressed Red Knot DNA while improving detection of other prey taxa. We detected horseshoe crab in the Fall fecal samples, suggesting their use goes beyond the spring migration period of the Red Knots. ABSTRACT Understanding the diets of migratory shorebirds such as the Red Knot (Calidris canutus) is essential for evaluating ...

Lysin and Lytic Phages Reduce Vibrio Counts in Live Feed and Fish Larvae

open access: yesMicroorganisms
Vibrio species are naturally found in estuarine and marine ecosystems, but are also recognized as significant human enteropathogens, often linked to seafood-related illnesses.

Cyclomorphosis in Size of the Cultured Rotifer, Brachionus plicatilis

open access: yes, 1980
Variation in morphological and physiological characteristics among the rotifers, Brachionus plicatilis cultured in nearly all over Japan, is obstacle for progress and spread of the rotifer culture technique.

Flood pulse are the main determinant of feeding dynamics and composition of Odontostilbe pequira (Characiformes: Characidae) in southern Pantanal, Brazil

open access: yesActa Limnologica Brasiliensia
Aim This study characterized the diet of Odontostilbe pequira in Porto Murtinho, Pantanal, Brazil, and evaluated the existence of spatial, temporal and ontogenetic variation in feeding. Methods A total of 303 individuals were analyzed from February 2009

Zooplankton reliance on autochthonous and allochthonous resources across mountain lakes revealed through essential amino acid δ13C analysis

open access: yesLimnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Terrestrial subsidies shape aquatic ecosystem structure and function, serving as important energy channels for consumers when phytoplankton and other autochthonous resources are limited. Despite this, quantifying the assimilation of allochthonous nutrients by aquatic consumers can be challenging. Here, we show terrestrial plants, benthic algae,

Genomic adaptation of the water flea Daphnia to elevated temperatures: Insights from power plant‐heated lakes

open access: yesLimnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Global warming increasingly threatens freshwater biodiversity, highlighting the need to understand how key ecological interactors, such as the zooplankton water flea Daphnia, genetically adapt to rising temperatures. Although local thermal adaptation has been documented in Daphnia, the underlying genomic changes remain poorly resolved.

Reduced expression of exocytotic proteins caused by anti-cholinesterase pesticides in Brachionus calyciflorus (Rotifera: Monogononta)

open access: yesBrazilian Journal of Biology
The organophosphate and carbamate pesticides methyl-parathion and carbaryl have a common action mechanism: they inhibit acetylcholinesterase enzyme by blocking the transmission of nerve impulses.

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...
