Validation Of Pcr-Based Assays And Laboratory Accreditation For Environmental Detection Of Aquatic Invasive Species, Invasive Species Advisory Committee
Validation Of Pcr-Based Assays And Laboratory Accreditation For Environmental Detection Of Aquatic Invasive Species, Invasive Species Advisory Committee
National Invasive Species Council
This white paper provides:
a) Background information on the use, accuracy and reliability of PCR-based assays such as environmentally sampled DNA (eDNA) for early detection of aquatic invasive species (AIS) and;
b) Recommendations for establishing a system for validating assays and accrediting laboratories that report on the presence or absence of AIS.
This white paper was developed by the members of ISAC and discusses the need for developing validation requirements for Polymerase Chain Reaction (PCR) and other DNA-based molecular assays that are increasingly being used to detect AIS. It does not provide a simplified checklist for evaluation of their ability …

A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell
Great Plains Research: A Journal of Natural and Social Sciences
As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …
