ABSTRACT The use of environmental DNA (eDNA) as a tool for monitoring represents a major innovative advance in environmental science, one that enables the detection of species without the need to observe or capture them. This article assesses the state of play of eDNA research targeting crayfish.

Background Land snails, especially the chocolate banded snails, Eobania vermiculata (Muller 1774) are destructive pests of a wide range of field and vegetable crops, and biological treatment appears to be better alternative to the chemical snail control.

Abstract Objective Flathead Catfish Pylodictis olivaris are a widespread aquatic invasive species within the United States and a recent invader in the Susquehanna River basin, Pennsylvania. Flathead Catfish are piscivores known to consume native and recreationally important fish species. In the mid‐Atlantic United States, it is unknown how this invader

Biodilution of Organic Species of Arsenic in Freshwater Food Webs
Abstract Arsenic can accumulate in freshwater biota, sometimes reaching potentially harmful levels. However, the toxicity of arsenic strongly depends on which arsenic species are present. Although organic species are considered less harmful than inorganic ones, they have not been extensively studied in freshwater environments, and drivers of variation ...

Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

Large‐scale validation of 46 invasive species assays using an enhanced in silico framework
It can be challenging to ensure that eDNA assays are specific to their intended targets, particularly when biodiversity is high and the geographic area is large. Here, we use an accurate machine‐learning‐based PCR model to streamline validation of 46 qPCR assays targeting invasive species throughout the continental United States. We present an overview
