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

Environmental DNA - An emerging tool in conservation for monitoring past and present biodiversity
TL;DR: The achievements gained through analyses of eDNA from macro-organisms in a conservation context are reviewed, its potential advantages and limitations are discussed, and it is expected the eDNA-based approaches to move from single-marker analyses of species or communities to meta-genomic surveys of entire ecosystems to predict spatial and temporal biodiversity patterns.

TL;DR: The use of eDNA metabarcoding for surveying animal and plant richness, and the challenges in using eDNA approaches to estimate relative abundance are reviewed, which distill what is known about the ability of different eDNA sample types to approximate richness in space and across time.

TL;DR: It is demonstrated that entire faunas of amphibians and fish can be detected by high-throughput sequencing of DNA extracted from pond water, underpin the ubiquitous nature of DNA traces in the environment and establish environmental DNA as a tool for monitoring rare and threatened species across a wide range of taxonomic groups.

TL;DR: In this paper, the authors examine the current frontiers of eDNA, outline key aspects requiring improvement, and suggest future developments and innovations for research, including improved ability to explore ecosystem-level processes, the generation of quantitative indices for analyses of species, community diversity, and dynamics, and novel opportunities through the use of time-serial samples and unprecedented sensitivity for detecting rare or difficult-to-sample taxa.

Allee Effects, Propagule Pressure and the Probability of Establishment: Risk Analysis for Biological Invasions
TL;DR: The concept of propagule pressure is reviewed to inquire if colonization theory might provide quantitative tools for risk assessment of biological invasions and to seek a synthesis of invasion biology and theoretical population biology.

Diet overlap among two Asian carp and three native fishes in backwater lakes on the Illinois and Mississippi rivers
TL;DR: Although rotifers were the most common prey item consumed by both bighead and silver carp, a negative relation between silver carp CPUE and cladoceran density was found, yet the potential for negative consequences of Asian carp in less productive ecosystems, including Lake Michigan, should not be underestimated.

TL;DR: Ten percent Clorox was found to eliminate all ethidium bromide-stainable DNA and to prevent PCR amplification of a 600-bp DNA segment within one minute of template treatment, and RNA was similarly destroyed.

TL;DR: This study illustrates that the combination of environmental niche- and vector-based models can provide managers with more precise estimates of invasion risk than can either of these approaches alone.
