Seasonal changes of pH and buffer capacity of aqueous homogenates of Vaccinium vitis-idaea and Vaccinium myrtillus leaves

open access: yesActa Societatis Botanicorum Poloniae, 2015
The newly formed leaves of both Vaccinium species show in June and July the lowest pH values, 3.4-3.7, which gradually increase up to 4.6 in November. The bi- and triennial leaves of Vaccinium vitis-idaea are less acid and show much morę limited seasonal

Does a decision support tool designed to depict West Nile virus risk explain variation in ruffed grouse Bonasa umbellus use of managed forests?

open access: yesWildlife Biology, EarlyView.
Infectious diseases are commonly cited as significant contributors to wildlife population declines. It is, therefore, important to investigate the extent to which tools designed to mitigate the effects of infectious diseases explain wildlife responses to habitat management.

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

open access: yesWildlife Biology, EarlyView.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

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 ...

Assessing habitat suitability for black grouse broods at the bioregional scale

open access: yesWildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

open access: yesWildlife 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.
