Spider Webs, Soil or Leaf Swabs to Detect Environmental DNA From Terrestrial Vertebrates: What Is the Best Substrate?

open access: yesMolecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT As human activities drive biodiversity decline, effective biomonitoring is more crucial than ever to track species distribution changes and inform conservation and restoration actions. Environmental DNA (eDNA) metabarcoding has emerged as a promising tool for the simultaneous detection of multiple taxa. However, while substrates play a crucial

A Practical Method to Assess Bird Strike Risk in Air Operations Using a Count‐Based Risk Mitigation Tool

open access: yesRisk Analysis, Volume 45, Issue 11, Page 3540-3553, November 2025.
ABSTRACT Bird strikes pose a risk to aviation. Collisions between birds and airplanes result in a threat to human lives, economic losses, and material damage. The majority of these collisions occur on airfields during takeoff and landing. Knowing what bird species are present on airfields, in what numbers, and relating that to the extent to which these

Application of passive acoustic monitoring to compare avian populations in perennial grasslands and croplands in Nebraska

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Using passive acoustic monitoring, researchers in Nebraska found that perennial grasslands support greater species richness of grassland obligates and at‐risk birds than croplands throughout most of the migration and breeding season. Abstract Perennial grasses, such as switchgrass (Panicum virgatum), have emerged as a promising and reliable feedstock ...
