Lara became interested in monitoring rare species as she researched Acadia’s bat community using acoustics and radio-telemetry. Her interests in rare species monitoring and geographic information systems led her to return to the University of Maine to pursue her Master’s degree.

Emma has collaborated with multiple agencies and stakeholders to capture and translocate 30 beavers that would otherwise have been euthanized. Emma is pleased that she, along with the beavers, is assisting in conservation and restoration efforts in a sensitive arid system.

Josh’s passion for wildlife and photography have blended well, as his photographs have been published in various outlets and displayed at several galleries. Notably, one of his photographs was selected by a National Geographic editor as a “Top Photo” during the 2017 nature photographer of the year competition.

Emma Doden, Utah Cooperative Fish and Wildlife Research Unit graduate, assessed the efficacy of translocating beavers to desert restoration sites. Beavers are ecosystem engineers, can serve as a cost-effective, natural alternative to human restoration efforts, and are especially important to arid western ecosystems.

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species.

Standard Fish Sampling Techniques

Examining environmental deoxyribonucleic acid (eDNA) in water samples has demonstrated promise for identifying fish species present in water bodies. However, whether or not this same approach can be used to assess relative abundance, biomass, and species composition in large (greater than [>] 200-hectare) waterbodies is unclear.
