Changes in trends of the height growth of spruce and pine derived from continuous measurements in forest management plans of Kostelec nad Černými lesy and on pilot research plots in the Czech Republic

open access: yesJournal of Forest Science, 2004
In changing growth conditions, methodical procedures should concentrate on the investigation of processes currently under way in forests. Many studies have shown that present models of forest growth parameters differ from previous surveys as far as for ...

Why wolves walk – drivers of daily movement in a social large carnivore

open access: yesWildlife Biology, EarlyView.
Animal movement patterns are influenced by a range of extrinsic and intrinsic factors, including the distribution of resources, human disturbance, landscape connectivity, species interactions, and individual traits. We examined factors associated with daily movement distance (DMD) and linearity in 20 territorial Scandinavian wolves Canis lupus during ...

Isotope ratios and concentration of N in needles, roots and soils of Norway spruce (Picea abies [L.] Karst.) stands as influenced by atmospheric deposition of N

open access: yesJournal of Forest Science, 2005
This study aims to investigate the changes in isotope ratios in foliage and soils of two Norway spruce (Picea abies [L.] Karst.) forests greatly differing in their atmospheric N deposition and climatic conditions.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

open access: yesWildlife 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

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.
