Illuminating the Arctic: Unveiling seabird responses to artificial light during polar darkness through citizen science and remote sensing

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Artificial light at night (ALAN) has global impacts on animals, yet its effects in polar regions remain underexplored. In this study, we analyzed a decade of citizen science data on seabird occurrences in Longyearbyen, using remote sensing data to assess the impact of ALAN during the polar night.

The secret acoustic world of leopards: A paired camera trap and bioacoustics survey facilitates the individual identification of leopards via their roars

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Here, we conducted the first large‐scale joint camera trap and bioacoustics survey for large African carnivores in Nyerere National Park, Tanzania. By combining the different data types that each technology produced, this led to the discovery that every leopard has a unique, identifiable roar which enables leopards to be the focus of other, more ...

Quantifying nocturnal bird migration using acoustics: opportunities and challenges

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we explore three migration intensity measures derived from acoustic recordings, that is, bird call and passage rates, and species diversity, for their usefulness in quantifying nocturnal bird migration rates at three taxonomic levels: birds, passerines and thrushes, as estimated by a dedicated bird radar. Bird passage rates, that is, the
