Efficient Automatic Pollen Recognition From Fossil Pollen Samples: A High‐Resolution Example Record From Palaeolake Kieshofer Moor, Northeastern Germany

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We applied the two‐stage, AI‐based TOFSI approach to test automatic pollen recognition with fossil pollen samples. The algorithm performs very well for all major pollen types and other non‐pollen object classes, suggesting that such tools have the potential to substantially increase the efficiency of pollen analysis.

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

open access: yesEcohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

Temporal shifts in kelp forest structure and distribution largely reflect recent ocean warming trends

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...

Using LiDAR to quantify, map, and conserve late‐successional and old‐growth forest in Maine, USA

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract The world continues to lose late‐successional and old‐growth (LSOG) forest as the human population and demand for wood fiber grow. However, older forest age classes provide structural and compositional characteristics important to biodiversity that are often not present in forests managed for timber.
