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

Assessing Environmental DNA Detection in Controlled Lentic Systems
TL;DR: The objectives were to determine the most effective water stratum for e DNA detection, estimate true and false positive eDNA detection rates, and assess the number of water samples necessary to minimize the risk of false negatives.

Environmental DNA (eDNA) Shedding and Decay Rates to Model Freshwater Mussel eDNA Transport in a River
TL;DR: It is determined that eDNA shedding was statistically similar across mussel densities, but that first-order decay constants varied between experimental treatments, and a model is presented that can be used as a complementary tool to estimate mussel density.

TL;DR: Internal standard DNAs were added to eDNA samples from a coastal marine ecosystem in Maizuru Bay, Japan and metabarcoding analysis was performed using Illumina MiSeq to simultaneously identify fish species and quantify fish eDNA copy numbers, suggesting that eDNA metabarcode with standard DNA enabled useful quantifications of eDNA.

How will the ‘molecular revolution’ contribute to biological recording?
TL;DR: It is argued that eDNA surveys offer exciting new opportunities to engage the public in biological recording and that molecular approaches will complement conventional surveys, enabling unprecedented insights into species distributions and there is a need to rapidly establish ways of managing molecular records.

TL;DR: This study provides a comprehensive record of primary introductions of NIS for marine environments in the circumpolar Arctic and identifies knowledge gaps and opportunities for NIS research and management, contributing to the knowledge base needed to address two aspects of global change—invasive species and climate change.

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.
