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 ...

Journal of Quaternary Science, EarlyView.ABSTRACT Openwork mountain block deposits (blockfields, blockstreams) have received much research interest globally given their visual appeal as prominent cold‐region landforms. However, studies have shown that these landforms in both glaciated and non‐glaciated environments are probably of considerable age (pre‐Quaternary), yet the environmental ...
