Estimation of spatiotemporal trends in bat abundance from mortality data collected at wind turbines. [PDF]
Conserv Biol, 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

Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract To evaluate conservation interventions, it is necessary to obtain reliable population trends for short (<10 years) time scales. Telemetry can be used to estimate short‐term survival rates and is a common tool for assessing population trends, but it has limitations and can be biased toward specific behavioral traits of tagged individuals ...

Evaluating the impact of private land conservation with synthetic control design
Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract Programs to protect biodiversity on private land are increasingly being used worldwide. To understand the efficacy of such programs, it is important to determine their impact: the difference between the program's outcome and what would have happened without the program.

Extinction debt and functional traits mediate community saturation over large spatiotemporal scales
Journal of Animal Ecology, Volume 92, Issue 11, Page 2228-2239, November 2023., 2023 This study is the first to simultaneously evaluate whether (1) community saturation can require lengthy timespans to be reached and (2) there is a limit to the number of ecological strategies that can coexist. Determining if these ideas are supported is fundamental for better understanding the possible outcomes of species invasions and climate change ...

Accounting for bias in prevalence estimation: The case of a globally emerging pathogen
Journal of Applied Ecology, Volume 60, Issue 9, Page 2007-2017, September 2023., 2023 These results highlight the importance of using robust inferences to inform disease risk assessments and to efficiently allocate limited resources during mitigation strategies of infectious diseases. The methods used here can be applied to a wide range of host–pathogen systems, and will be of interest to both researchers and practitioners aiming to ...

Journal of Biogeography, Volume 50, Issue 9, Page 1561-1575, September 2023., 2023 Abstract Aim Anthropogenic changes such as land use and climate change affect species' geographic ranges, causing range shifts, contractions, or expansions. However, data on range dynamics are insufficient, heterogeneous, and spatially and temporally biased in most regions.

Journal of Animal Ecology, Volume 92, Issue 1, Page 158-170, January 2023., 2023 Introducing a statistical framework to estimate standardised dispersal kernels from biased data. The authors found strong evidence that long‐distance dispersal is common among European breeding bird species and across life stages. Their dispersal estimates for 234 bird species can guide selecting appropriate dispersal kernels in range expansion studies
