Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity [PDF]

, 2012
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, salinity exerts negative effects on ...

Heat Shock Proteins in Aquatic Larvae: Nutritional and Live Feed Modulation of Chaperone‐Mediated Stress Physiology in Fish and Shellfish

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Heat shock proteins (HSPs) are highly conserved molecular chaperones that maintain proteostasis under environmental and physiological stress. In aquaculture research, HSP responses have been studied primarily in relation to temperature, salinity, pollutants, and pathogens in juvenile and adult stages, whereas the nutritional regulation of HSP ...

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

Nano Select, Volume 7, Issue 2, February 2026.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Zooplankton Assemblage Structure of the Lower Mississippi River and Floodplain in Relation to Site Hydrological Connection

River Research and Applications, Volume 42, Issue 2, Page 400-414, February 2026.
ABSTRACT The pattern of flow or hydrological connection between a river's main channel and its floodplain can vary seasonally and spatially in frequency, duration, direction, and magnitude. Such variation is expected to promote habitat and biotic diversity.

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Ecotoxicological studies with the freshwater rotifer Brachionus calyciflorus

Ecotoxicology and Environmental Safety, 1993
The use of the freshwater rotifer Brachionus calyciflorus as a test organism for ecotoxicological studies was examined. Changes in the feeding-, swimming behavior- and demographic characteristics of the rotifers exposed to increasing concentrations of copper (Cu) were studied and the relationships between the different test parameters and their ...

Combined effect of concentrations of algal food (Chlorella vulgaris) and salt (sodium chloride) on the population growth of Brachionus calyciflorus and Brachionus patulus (Rotifera)

Revista de Biología Tropical, 2003
Salinity is an important variable influencing the density and diversity of rotifers. Studies on salt tolerance of rotifers have so far concentrated on euryhaline species while very little information is available on noneuryhaline taxa.

Germ cell specification and ovary structure in the rotifer Brachionus plicatilis

EvoDevo, 2010
Background The segregation of the germline from somatic tissues is an essential process in the development of all animals. Specification of the primordial germ cells (PGCs) takes place via different strategies across animal phyla; either specified early ...
