Evaluation of Rapid DNA Extraction Methods to Better Enable Point‐of‐Use Environmental DNA Detection

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
We investigated the most effective rapid DNA extraction methods for use in point‐of‐use eDNA detection. We found that two extraction solutions with short heating steps led to highest yield of eDNA from filters with spiked grass carp gill cells. ABSTRACT Recent developments in molecular testing have created the opportunity for biologists and managers to

To What Extent Can Life History Strategies Inform Reptile Conservation Planning?

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Conservation planners must effectively target interventions to reduce the extinction risk of species. If we can use a species' life history strategies to predict their responses to interventions, this offers a promising approach to better understand species extinction risks and conservation potential.
