Environmental DNA and crayfish management

In this post Matthew Dougherty discusses his recent paper ‘Environmental DNA (eDNA) detects the invasive rusty crayfish Orconectes rusticus at low abundances‘ Tangled buoy strings, lost traps, pinched fingers, sweaty brows, and boats smeared with beef liver: these images define the experiences of countless managers and scientists who use baited trapping to monitor crayfish invasions, especially in lakes of the upper Midwest, USA. While these … Continue reading Environmental DNA and crayfish management

The evolutionary canary in the coal mine

In this post Executive Editor Marc Cadotte discusses a paper he recently handled by François Keck and colleagues ‘Linking phylogenetic similarity and pollution sensitivity to develop ecological assessment methods: a test with river diatoms‘ Like canaries in coal mines, species can provide important information about deteriorating environmental conditions. A whole sub-discipline of environmental biomonitoring has emerged to provide the necessary tools to evaluate biological responses … Continue reading The evolutionary canary in the coal mine
