Moose indifferent to canopy loss from forest disturbance by bark beetles

open access: yesThe Journal of Wildlife Management, EarlyView.
Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

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

open access: yesNordic 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 ...

Intersectional Hybrids of the Relict Species, Box Huckleberry (Gaylussacia brachycera), with Dwarf Huckleberry (Gaylussacia dumosa)

open access: yesHortScience
Gaylussacia brachycera (box huckleberry) is a unique relict species and is the monospecific member of Gaylussacia sect. Vitis-idaea. As part of investigations to understand interspecific crossability in Gaylussacia, pollinations were made between ...

Dispersal and establishment both limit colonization during primary succession on a glacier foreland [PDF]

open access: yes, 2009
Plant colonization can be limited by lack of seeds or by factors that reduce establishment. The role of seed limitation in community assembly is being increasingly recognized, but in early primary succession, establishment failure is still considered ...

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

open access: yesOikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Seasonal variation of leaf functional traits in sub‐Arctic plants

open access: yesOikos, EarlyView.
Leaf functional traits are informative of plant fitness and functions in ecosystems. These functional traits and their variation across geographic extents are much studied but less is known about their temporal variation over a growing season. Here, we provide an analysis of the seasonal variation in six leaf functional traits of 11 sub‐Arctic vascular
