ABSTRACT Invasive alien mussels threaten freshwater ecosystems worldwide by disrupting food webs and nutrient cycling. The effective monitoring of these populations is therefore essential to assess their spread and ecological impacts. This study demonstrates the applicability of environmental DNA (eDNA) methods to monitor the reproductive periods of ...

Signatures of Wild Animal Life in Earth's Landscapes
Abstract Animals shape Earth surface processes and landforms by displacing Earth surface materials and by making them more or less susceptible to geophysical processes. Despite increased recognition of the global significance of animal landscape “signatures”, analysis of their magnitude and generality has not been possible until now.

Muddied waters: suspended sediment impacts on gill structure and aerobic scope in an endangered native and an invasive freshwater crayfish [PDF]
Suspended sediment (SS) loadings in freshwater habitats have increased over the past century and SS is now a significant environmental stressor. Greater tolerance to environmental stressors has been proposed as a factor in the success of aquatic invasive
