Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Litter nutrient release and allelopathy jointly contribute to the diversity–invasibility relationship

open access: yesFunctional Ecology, EarlyView.
Abstract Elton's biotic resistance hypothesis suggests that diverse communities are more resistant to biological invasions. While below‐ground mechanisms play a crucial role in regulating the diversity–invasibility relationship, the role of litter as a key regulator of below‐ground processes remains underexplored. We used 15 common native plant species

Light and ungulate browsing interact in shaping future woody plant diversity through natural regeneration

open access: yesJournal of Applied Ecology, EarlyView.
Our results provide strong evidence that in the current context of increasing tree mortality and subsequent light availability, roe deer act as a keystone species. It is crucial to implement browsing protection measures and control roe deer population before or immediately after canopy disturbance.

Apomixis and Hybridization Drives Reticulate Evolution and Phyletic Differentiation in Sorbus L.: Implications for Conservation

open access: yesFrontiers in Plant Science, 2018
Hybridization and polyploidy are major forces in the evolution of plant diversity and the study of these processes is of particular interest to understand how novel taxa are formed and how they maintain genetic integrity.

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Continuous quantification of forest microclimate temperatures in space and time using fibre‐optic technology

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Most species experience microclimate temperatures, that is, variable and fine‐grained thermal conditions determined by atmospheric conditions interacting with biotic and abiotic components of the earth's surface. Unfortunately, measuring microclimates at biologically meaningful grain sizes is challenging.

A Chalcone Glycoside from the Fruits of Sorbus commixta Hedl.

open access: yesMolecules, 2009
Sorbus commixta Hedl. (Rosaceae) has been traditionally used in oriental countries for the treatment of asthma and other bronchial disorders. In this study, a chalcone glycoside was isolated from the ethyl acetate extract of the fruits of this plant. The
