Forest Heterogeneity by Chain Saw: How Between‐Patch Variation in Old Growth Attributes Changes the Metacommunities of Beetles Metacommunity theory has expanded our understanding of how spatial dynamics and local interactions influence species communities, but we lack empirical studies specifically in terrestrial habitats te...

New paper on metacommunity dynamics out! šŸ“ƒšŸ Led by Oliver Mitesser we show that habitat heterogeneity shifts communities from patch-dynamics toward mass effects and species sorting using beetles as focal taxon. šŸžšŸ˜

Informatics student project: Enhancing deep learning techniques to detect animal paths in UAV imagery When animals roam the savanna, e.g. to find resources, they leave distinctive paths in the landscape. The resulting path networks show how animals differentiate and interact with their environment. Information on the animals’ space use at great spatial detail is important to understand their selection behavior. However, conventional methods for deriving animal paths such as […]

Mapping snow-ecosystem interactions from UAS: EORC at Arctic System Science Conference 2026 This week, the Arctic System Science Conference 2026 has been taking place in Potsdam. Hosted by the Alfred Wegener Institute (AWI), the conference offers a place for researchers to exchange on past, present and future scientific research of the Arctic system – including oceanic, sea-ice, atmospheric, ecosystem, bio-geochemistry and anthropology research. The Earth Observation Research […]

At the Arctic System Science Conference 2026, we presented research on deriving spatially-continuous snow depth data at cm-resolution using UAV-borne LiDAR on Svalbard. A great event for connecting with polar researchers!

New publication: Mapping animal paths using drones and deep learning We’re pleased to share our latest open-access research on automatically detecting animal paths in Africa’s Kruger National Park using drone imagery and deep learning. Published in Ecological Informatics, our study demonstrates how deep learning can be employed to identify the network of trails created by animals as they move across the landscape. Using a UNet […]

Snow depth is a crucial variable in high-arctic ecosystems, as it affects soil, plants & wildlife foraging. Yet, spatially-continuous snow depth data is rare.

Happy about all the interest shown in RStoolbox at #LPS25! Had the chance to discuss the role of R in EO, how R+Python integrate, and what drives programming language preference (e.g. when research communities implement their methods predominantly in one language, creating unique package ecosystems)
