Food Risk Assess Europe, Volume 3, Issue 2, April 2025.Abstract Plant pests, particularly non‐native species, can have a profound impact on their host plants. Trees are the foundation of forest ecosystems and serve as important structures in agricultural landscapes and urban areas. In Sweden, forests cover around 70 % of Sweden's land area and serve as an important national resource for the economy and for

What Are the Limits to the Growth of Boreal Fires?
Global Change Biology, Volume 31, Issue 3, March 2025.Fires in East Siberia have been increasing, releasing record greenhouse gas emissions. To understand what stops these fires from spreading, we analyzed fire perimeters from satellite data covering 27,000 fires between 2012 and 2022. We found that fire weather conditions and landscape features, like roads and previous burns, play key roles in limiting ...

Tree water uptake patterns across the globe
New Phytologist, Volume 242, Issue 5, Page 1891-1910, June 2024.Summary Plant water uptake from the soil is a crucial element of the global hydrological cycle and essential for vegetation drought resilience. Yet, knowledge of how the distribution of water uptake depth (WUD) varies across species, climates, and seasons is scarce relative to our knowledge of aboveground plant functions.
