Estimation of spatiotemporal trends in bat abundance from mortality data collected at wind turbines
Conservation Biology, Volume 35, Issue 1, Page 227-238, February 2021., 2021 Abstract Renewable energy sources, such as wind energy, are essential tools for reducing the causes of climate change, but wind turbines can pose a collision risk for bats. To date, the population‐level effects of wind‐related mortality have been estimated for only 1 bat species. To estimate temporal trends in bat abundance, we considered wind turbines

Considering connections between Hollywood and biodiversity conservation
Conservation Biology, Volume 32, Issue 3, Page 597-606, June 2018., 2018 Abstract Cinema offers a substantial opportunity to share messages with a wide audience. However, there is little research or evidence about the potential benefits and risks of cinema for conservation. Given their global reach, cinematic representations could be important in raising awareness of conservation issues and species of concern, as well as ...
