Journal 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 ...

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Wildlife Biology, EarlyView.Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Visual Parameterization of Vaganov-Shashkin Simulation Model and its Application in Dendroecological Research [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2015 There are many different methods and tools for data analysis in dendrochronology. Modeling is one of them. One of the main issues in modeling is a choice of the main factors.

Micro‐habitat selection by boreal woodland caribou improves access to food
Wildlife Biology, EarlyView.Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

TORREFACTION OF BEECH AND SPRUCE SAWDUST [PDF]
Pro Ligno, 2014 This paper aims to apply a thermal treatment of beech and spruce sawdust dried to 10% moisture in order to determine the mass loss and to obtain pellet sets. This paper considers the colour change of the treated material during the treatment, as function
