\u3cem\u3ePicea abies, Picea glauca, Picea omorika, Picea pungens\u3c/em\u3e Cone

, 2014
Picea cones are often erect when first forming and pendulous at maturity. The size, shape, color and texture of the cones of Picea confirm the identity of the species. Even the scale margin features can be important.

Plant functional groups and root traits are linked to exudation rates of mature temperate trees

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudation affects soil biogeochemistry profoundly, yet it is rarely quantified in mature, field‐grown trees and its controls are poorly understood. We measured rates of carbon (C) exudation in 11 tree species that exhibit divergent root traits, including ...

Ectomycorrhizal community composition and extramatrical hyphal proportion predict soil carbon stocks at the landscape scale

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While fungal composition has been linked to soil carbon at global scales, these patterns are often difficult to disentangle from broad climatic gradients and species range limits. To address this constraint, we tested which aspects of ectomycorrhizal community structure

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

Journal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

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,
