Modern pollen rain of an upland area: implications of pollen dispersal for interpreting palaeoenvironmental records

open access: yesBoreas, EarlyView.
A long‐term perspective on landscape evolution is critical for understanding past land‐use activity, land cover–climate feedbacks and, notably, for establishing a factual basis for conservation. Fossil pollen analysis provides a means to achieve this. Biases pertaining to pollen productivity, pollination processes and basin size, however, mean there is

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees

open access: yesEcological Entomology, EarlyView.
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

Woody vegetation can promote pollinator biodiversity in semi‐natural grasslands

open access: yesInsect Conservation and Diversity, EarlyView.
Up to 24% shrub cover in Swedish semi‐natural grasslands is positively related to butterfly diversity, while butterfly diversity increases up to 18% deciduous hardwood tree cover. Initially positive effects of tree and shrub cover on butterfly abundance were detected on those butterflies that use trees and shrubs as host plants.

Balancing Risk and Reward: Red Fox Exploitation of Kill Sites in a Wolf‐Occupied Landscape

open access: yesJournal of Zoology, EarlyView.
Wolves are recolonising the European Alps, and the carcasses they leave behind are a valuable food source for smaller carnivores. Using camera traps at 26 wolf‐killed red deer carcasses in Stelvio National Park, we found that red foxes visited every carcass and timed their visits according to how much meat was left, rather than to whether wolves were ...

Contrasting elevational patterns in microbial necromass carbon content and contribution across soil depths of a subtropical alpine ecosystem

open access: yesEcological Processes
Background Microbial necromass carbon (MNC) is a critical component of persistent soil organic carbon (SOC). However, the elevational patterns of MNC accumulation and its contribution to SOC across different soil layers remain poorly understood in ...

The craters that never were: Anthropogenic origins of alleged impact structures in the Chiemgau region

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Public fascination with impact craters often drives bold speculations, but rigorous verification is critical. In southeastern Bavaria, numerous depressions have been proposed to represent impact craters associated with a catastrophic event in Celtic times (between 900 BC and 600 BC)—the so called “Chiemgau Impact.” To date, the evidence ...

‘Merge my breath with the one of nature’: Qualitative analysis on focus groups exploring how nature exposure could improve positive body image in young women

open access: yesPsychology and Psychotherapy: Theory, Research and Practice, EarlyView.
Abstract Objectives Nature exposure may support young women in improving their relationship with their body, enhancing positive body image. However, the mechanisms remain still largely underexplored. A few qualitative studies provided valuable insights, but they lacked generalizability to the broader population of young women, since they often relied ...

Fungi contribute more than bacteria to the ecological uniqueness of soil microbial communities in alpine meadows

open access: yesGlobal Ecology and Conservation
Understanding the ecological uniqueness of soil bacterial and fungal communities and their driving factors can provide more targeted protection for soil microbial diversity.

Mowing Modulates Nitrogen Saturation Thresholds of Aboveground Productivity in a Meadow Steppe via Dominant Species and Stoichiometric Regulation

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
Aboveground net primary productivity (ANPP) reached saturation at approximately 10 g N m−2 year−1, while mowing increased the nitrogen saturation threshold to a higher nitrogen‐addition level. This nonlinear saturation response was mainly driven by increased dominance of the dominant species, with plant stoichiometric thresholds further promoting the ...

Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

open access: yesReviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.
