The trace element boron is a bioactive and potentially essential element for humans with a broad range of physiological effects. While dietary sources of boron are well known, significant knowledge gaps remain regarding boron intake in special dietary patterns. We estimated dietary boron intake and quantified urinary boron excretion in long-term lacto-ovo-vegetarians, vegans and omnivores in Germany. Dietary intake was estimat...

Central Europe has been a hotspot of forest disturbance during 2018–2020, with large pulses of tree mortality from drought and bark beetles. Post‐disturbance recovery is crucial for forest resilience and the continued provision of ecosystem services. We surveyed 849 plots in disturbance hotspots across 10 Central European countries to assess the state of early (3–5 years) post‐disturbance tree regeneration. Our specific object...

Adaptation to siliceous versus carbonate substrates is thought to be an important driver of speciation in the alpine flora. The role of the pollination system in the formation and maintenance of such species is presently unclear. Here, we chose three species pairs in the genera Gentiana , Primula , and Rhododendron which often occur in geographic proximity or even sympatry to study the existence of pollination barriers in thes...
