Wildlife Biology, EarlyView.Tree cavities and nestboxes are crucial resources for cavity‐nesting birds. While cavities are essential for reproduction, their importance outside the breeding season remains poorly understood, with most existing evidence focusing on nestbox use by small birds to reduce heat loss during winter.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer
Wildlife Biology, EarlyView.Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

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.

Behavioral response of moose Alces alces to summer heat stress
Wildlife Biology, EarlyView.Minnesota moose are heat‐stressed during summers, which is adversely impacting their survival. We used both movement and activity data to explore the behavioral responses of Minnesota moose experiencing heat stress, termed ‘hot moose events' or HMEs, to understand how both ambient temperature and available habitat contribute to the ability of these ...

Mechanisms of resistance of white spruce to the spruce bud moth
The Forestry Chronicle, 1996 There is a genetic basis to resistance of open-grown white spruce trees to their primary pest, the spruce bud moth, Zeiraphera canadensis Mutt. & Free. Resistance is attributable to late budburst and unknown factors associated with higher predation and parasitism of eggs and mortality of old larvae.
