Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

Nordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae

Nordic Journal of Botany, EarlyView.
Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

Nordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

What does coexistence mean? Insight from place‐based trajectories of pastoralists and bears encounters in the Pyrenees

People and Nature, EarlyView.
Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

Faunistics of oribatid mites (Acari, Oribatida) in dry grassland sites in the Eisack Valley (South Tyrol, Prov. Bolzano, Italy)

Soil Organisms, 2018
Oribatid mites were investigated in five dry grassland sites in the basin around Klausen / Chiusa (South Tyrol). Soil and litter samples were taken from characteristic microhabitats (dry grassland, dry bushland, rocky steppe).

Pastoralist views and positions on coexistence with large carnivores. An overview from conflict areas across Europe

People and Nature, EarlyView.
Abstract While large carnivore expansion is a conservation success, it increasingly challenges pastoralism. Beyond economic value, pastoralism provides critical biodiversity and sociocultural benefits, recognized by the UN and the EU's ‘High Nature Value farming’ designation.

Reverse shoulder arthroplasty with a 155° neck-shaft angle inlay implant design without reattachment of the subscapularis tendon results in satisfactory functional internal rotation and no instability: a cohort study

Journal of Orthopaedics and Traumatology
Background The aim of this study was to use the Activities of Daily Living which require Internal Rotation (ADLIR) questionnaire to assess the functional internal rotation in patients who had undergone reverse shoulder arthroplasty (RSA) without ...

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...
