Dwarf shrub hydraulics: two Vaccinium species (Vaccinium myrtillus, Vaccinium vitis‐idaea) of the European Alps compared [PDF]
Physiologia Plantarum, 2015 Vaccinium myrtillus and Vaccinium vitis‐idaea are two dwarf shrubs widespread in the European Alps. We studied the hydraulics of these species hypothesizing that (1) the hydraulic architecture of dwarf shrubs differs from trees, (2) hydraulic properties reflect the species' ecological amplitude and (3) hydraulic properties vary spatially and seasonally.

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

Edinburgh Journal of Botany, 2010 Variation among 19 phenological features taken from 48 species of Vaccinium (Ericaceae), both in vivo and in vitro as well as from existing literature, were subjected to several clustering strategies. Our results suggest three distinct phenological clusters that reflect the ability of these taxa to tolerate frost, namely a ‘Tropical’ group of 16 taxa ...

Seasonal variation of leaf functional traits in sub‐Arctic plants
Oikos, 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

Fine-Scale Plant Species Identification in a Poor Fen and Integration of Techniques and Instrumentation in a Classroom Setting [PDF]
, 2015 Refining carbon flux measurements in the carbon cycle is an ongoing challenge. This study attempted to identify plant species in Sallie’s Fen, a nutrient-poor fen in Barrington, New Hampshire, at a fine scale in order to better model and understand ...

New species and records of Stenus (Nestus) of the canaliculatus group, with the erection of a new species group (Insecta: Coleoptera: Staphylinidae: Steninae) [PDF]
, 2012 The canaliculatus species group of Stenus (Nestus) is redefined. Four new Palaearctic species of the group are described and illustrated: S. (N.) alopex sp. nov. from the Putorana Highland and Taymyr Peninsula, Russia; S. (N.) canalis sp. nov.

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 ...
