Glycosaminoglycans in Anodonta californiensis, a Freshwater Mussel
The Biological Bulletin, 1993 The synthesis of glycosaminoglycans (GAG) in a freshwater mussel was studied in organ culture using labeled precursors. The major GAGs synthesized were determined and characterized by chemical and enzymatic methods. They were shown to be heparin and an unusual type of heparan sulfate. Gills produced about 50% of each polymer; mantles synthesized little

Ecosystem engineers and functional dominance: when species loss matters for ecosystem function
Oikos, EarlyView.Understanding when and why species loss affects community function in natural communities remains an open question in ecology. Recent cross‐system analyses have shown that functional dominance is associated with whether species loss matters: in communities dominated by few high‐performing species, lost species contribute little to function.

People and Nature, EarlyView.Abstract Nature‐based solutions (NbS) have become central to environmental governance. Yet, their societal legitimacy depends on how they are framed in public discourse. This study investigates how Norwegian media actors construct narratives around NbS, whose voices are amplified, and the extent to which plural and Indigenous epistemologies are ...

Environmental Toxicology, EarlyView.ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

The complete mitochondrial genome of a freshwater mussel Nodularia douglasiae (Bivalvia: Unionidae)
Mitochondrial DNA. Part B. Resources, 2018 The circular F-type mitochondrial genome (15,761 bp) was completely sequenced for a Korean freshwater mussel Nodularia douglasiae (synonym Unio douglasiae; Unionidae, Unionida, Bivalvia).

Environmental Toxicology, EarlyView.ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Limitations of beta diversity in conservation site selection
Ecological Indicators, 2023 Preservation of diversity is a key issue in many conservation efforts. It has recently been suggested that beta diversity should be considered in conservation planning and that sites with high local contribution to beta diversity (LCBD) may be valuable ...

Environmental Toxicology, EarlyView.ABSTRACT Terrestrial detritivores such as isopods and springtails play a vital role in cycling nutrients through soil ecosystems. Microplastics (MPs, < 5 mm) are increasingly recognized as contaminants of terrestrial soils, yet little is known about whether soil invertebrates themselves are impacted by consuming these plastics or if they can generate ...

Survival, growth and condition of freshwater mussels: effects of municipal wastewater effluent.
PLoS ONE, 2015 Freshwater mussels (Family Unionidae) are among the most imperiled group of organisms in the world, with nearly 65% of North American species considered endangered.

Wildlife Letters, EarlyView.The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...
