Surveys of environmental DNA (eDNA): a new approach to estimate occurrence in Vulnerable manatee populations

open access: yesEndangered Species Research, 2018
Environmental DNA (eDNA) detection is a technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. For eDNA measurement, genetic material shed into the environment is concentrated

Side‐Scan Sonar as a Tool For Measuring Fish Populations: Current State of the Science and Future Directions

open access: yesFisheries, Volume 49, Issue 10, Page 454-462, October 2024.
Side‐scan sonar (SSS) is a powerful tool that can be used to address many key questions in fisheries science. In principle, SSS uses dual transducers to transmit a narrow‐beam, wide‐angle acoustic signal as the survey vessel transits an area. The intensity of reflected sound is recorded to generate an image mosaic comprised of benthic substrates and ...

Flagship individuals in biodiversity conservation

open access: yesFrontiers in Ecology and the Environment, Volume 22, Issue 1, February 2024.
Flagship species are an important tool for mobilizing support for conservation. Here, we extend this concept to include individual organisms, whose characteristics, fates, and connections to people can garner public attention, attract conservation support, and spur activism.
