TLDR
Quantitative comparisons with traditional fisheries surveillance tools illustrate the greater sensitivity of eDNA and reveal that the risk of invasion to the Laurentian Great Lakes is imminent.Abstract:
Effective management of rare species, including endangered native species and recently introduced nonindigenous species, requires the detection of populations at low density. For endangered species, detecting the localized distribution makes it possible to identify and protect critical habitat to enhance survival or reproductive success. Similarly, early detection of an incipient invasion by a harmful species increases the feasibility of rapid responses to eradicate the species or contain its spread. Here we demonstrate the efficacy of environmental DNA (eDNA) as a detection tool in freshwater environments. Specifically, we delimit the invasion fronts of two species of Asian carps in Chicago, Illinois, USA area canals and waterways. Quantitative comparisons with traditional fisheries surveillance tools illustrate the greater sensitivity of eDNA and reveal that the risk of invasion to the Laurentian Great Lakes is imminent.read more

TL;DR: In this article, the effects of removing a weir in the river Lugg (England) had been suggested to have a detrimental effect on salmonid migration, and they employed a powerful Before-After-Downstream-Upstream (BADU) approach using environmental DNA (eDNA) metabarcoding.

Improving ecological surveys for the detection of cryptic, fossorial snakes using eDNA on and under artificial cover objects
TL;DR: This work describes the design and validation of a new quantitative real-time polymerase chain reaction (qPCR)-based eDNA eCOTE3 assay with high specificity and sensitivity for sharp-tailed snake, an endangered species under the Canadian Species at Risk Act.

The role of propagule pressure in explaining species invasions.
TL;DR: Propagule pressure is proposed as a key element to understanding why some introduced populations fail to establish whereas others succeed and how the study of propagule pressure can provide an opportunity to tie together disparate research agendas within invasion ecology.

Species detection using environmental DNA from water samples.
TL;DR: A novel approach, based on the limited persistence of DNA in the environment, to detect the presence of a species in fresh water, using specific primers that amplify short mitochondrial DNA sequences to track the existence of a frog in controlled environments and natural wetlands.

TL;DR: The Ecological Society of America recommends that the federal government take the following six actions: use new information and practices to better manage commercial and other pathways to reduce the transport and release of potentially harmful species, and establish a National Center for Invasive Species Management.

An ounce of prevention or a pound of cure: bioeconomic risk analysis of invasive species
TL;DR: A quantitative bioeconomic modelling framework is presented to analyse risks from non–indigenous species to economic activity and the environment, and it is shown that society could benefit by spending up to US$324 000 year−1 to prevent invasions into a single lake with a power plant.
