Risk factors for bark stripping damage on Norway spruce by red deer
Wildlife Biology, EarlyView.Norway spruce Picea abies is an economically important tree species in Europe, actively managed for forestry. Among the most negative biotic factors for growth and hence forest production is damage caused by wildlife, such as damage through bark stripping by red deer Cervus elaphus.

Biomass-modulated fire dynamics during the last glacial-interglacial transition at the central pyrenees (Spain) [PDF]
, 2014 Understanding long-term fire ecology is essential for current day interpretation of ecosystem fire responses. However palaeoecology of fire is still poorly understood, especially at high-altitude mountain environments, despite the fact that these are ...

The effects of moose and pine density on browsing damage in Swedish pine forests
Wildlife Biology, EarlyView.Moose Alces alces is a culturally and economically important game species in Sweden, but their browsing on regenerating Scots pine trees Pinus sylvestris often causes extensive damage to the production and quality of timber. Forest and wildlife managers are faced with the dilemma of how to reduce damage to timber trees while also supporting moose ...

Impact of pine looper defoliation in Scots pine [PDF]
, 2003 Widespread defoliation of forests caused by insects or fungi cause economic losses throughout the world. Successful outbreak management involves cost/benefit estimation and requires knowledge of potential yield losses. Currently, such knowledge is scarce.

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris
Wildlife Biology, EarlyView.Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.

Recovery kinetics of winter stressed conifers: The effects of growth light environment, extent of the season, and species. [PDF]
, 2010 Evergreens undergo a dramatic reduction in their maximal photochemical efficiency (measured as Fv/Fm) during winter, which is largely due to increases in a sustained form of thermal energy dissipation.
