The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

International Review of Hydrobiology, EarlyView.Amino Acid Isotope Analysis of Gammarus sp. at the river Boye catchment. ABSTRACT Understanding the trophic ecology and nutrient dynamics of freshwater invertebrates is crucial for evaluating the function and resilience of ecosystems. Although bulk stable isotope analysis is widely used to investigate food web structures, it lacks the resolution ...

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND This study investigated the effects of different culture modes – autotrophy, mixotrophy and heterotrophy – on polyglucan accumulation and molecular weight distribution in four Galdieria sulphuraria strains. Understanding the impact of these culture modes helps optimize the production of reserve carbohydrates and modify their ...

Oxygen Consumption of the River Nerite Theodoxus fluviatilis in Different Salinities
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT The river nerite Theodoxus fluviatilis (Linneaus, 1758) is an euryhaline osmoconformer found in freshwater (FW) and brackish water (BW) habitats across Europe and western Asia. In northern Germany, T. fluviatilis forms regional subgroups, the FW and the BW ecotypes. Members of these ecotypes differ in shell morphology and in shell size as well

Grazer‐induced bioluminescence and toxicity in marine dinoflagellates
Limnology and Oceanography, EarlyView.Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...
