The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated 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 ...

Genetic Diversity and Phylogeographic Structure of the Edible Caterpillars of Gynanisa maja and Implications for the Sustainability of the Species in Namibia

open access: yesIntegrative Conservation, EarlyView.
Assessing the genetic diversity of edible insects harvested from the wild is a pre‐requisite for designing conservation and management policies. The caterpillars of Gynanisa maja (Saturniidae) are harvested in large numbers in mopane woodlands in southern Africa, where they represent a seasonal source of income and nutrition to many rural communities ...

Assessing the Acute and Chronic Effects of Palladium on Daphnia magna and the Influence of Natural Organic Matter

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT In recent decades, rising industrial demand for palladium (Pd), driven by its unique properties and affordability compared to other noble metals, has increased its environmental release into aquatic systems. This highlights the need to assess its effects on organisms, given the lack of standardized toxicity studies and regulations for this ...
