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

Wildlife 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.

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Large Planting Stock Type and Mechanical Release Effects on the Establishment Success of Picea glauca Plantations in Quebec, Canada

International Journal of Forestry Research, 2012
We established four experimental plantations to evaluate the main and interaction effects of timing (year of application) of mechanical release and stock type (containerized or bareroot) on the establishment success of large Picea glauca seedlings eight ...

Comparative Genomics Analysis of Repetitive Elements in Ten Gymnosperm Species: “Dark Repeatome” and Its Abundance in Conifer and Gnetum Species

Life, 2021
Repetitive elements (RE) and transposons (TE) can comprise up to 80% of some plant genomes and may be essential for regulating their evolution and adaptation.

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

Integrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Physiology and Transcriptomics Reveal Divergent Strategies of Mycorrhiza‐Mediated Drought Adaptation in Poplar

Plant, Cell &Environment, EarlyView.
ABSTRACT Mycorrhizal symbiosis shapes plant growth and stress resilience. Here, we compared physiological and molecular responses of poplars (P. x canescens) colonised by Paxillus involutus (Pi) or Cenococcum geophilum (Cg) under control conditions, drought stress and recovery.

Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

Plant, Cell &Environment, EarlyView.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.

Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

Plant Biology, EarlyView.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Local site conditions drive climate–growth responses of Picea mariana and Picea glauca in interior Alaska

, 2016
The growth response of boreal forest trees to projected changes in climate will have wide ranging and cascading impacts on disturbance regimes, climate feedbacks, carbon storage, and habitat ranges for flora and fauna.
