The boreal forests of Fennoscandia are largely dominated by Norway spruce and Scots pine. Conifer monocultures have been favoured in forest management during the last decades. Recently, concern has risen that consisting only one tree species could be vulnerable to biotic damage. Additionally, environmental societal changes placing new demands on utilization, thus shifting focus alternative options providing a wider scale ecosystem services. It proposed mixed better than with respect...
The adaptation of different species to warming temperatures has been increasingly studied. Moose (Alces alces) is the largest ungulate occupying northern latitudes across globe, and in Finland it most important game species. It very well adapted severe cold temperatures, but a relatively low tolerance warm temperatures. Previous studies have documented changes habitat use by moose due high In many these studies, used areas classified according how much thermal cover they were assumed offer...
Anthropogenic changes to land use drive concomitant in biodiversity, including that of the soil microbiota. However, it is not clear how increasing intensity human disturbance reflected microbial communities. To address this issue, we used amplicon sequencing quantify microbiota (bacteria and fungi) forests (n = 312) experiencing four different uses, national parks (set aside for nature conservation), managed (for forestry purposes), suburban (on border an urban area) (fully within a town or...
The incidence of tick-borne encephalitis (TBE) in humans has increased Finland, and the disease emerged new foci. These foci have been investigated to determine circulating virus subtype, tick host species ecological parameters, but countrywide epidemiological information on distribution TBEV limited. In this study, we screened sera from hunter-harvested wild cervids for presence antibodies against (TBEV) with a hemagglutination inhibition test. positive results were confirmed by...
Abstract For the calculation of carbon balance, estimates litterfall are needed as a measure accumulation into soil. Estimation should reflect structural and functional properties stands that affected by changes in growing conditions caused, for example, management activities or climate change. In this context, possibilities taking account dynamic relationship between were analysed correlating with growth trees. As extensive data modelling difficult to obtain, existing literature formulate...
Abstract During deep snow conditions, wildlife must balance between minimizing movements to conserve energy while seeking high amounts of browse gain the energy. Knowledge how begins hinder their is therefore vital when predicting wintertime behavior. We assessed phenomenon with moose. Movement data from 122 GPS-collared moose were integrated depth designated measurement stations. The effects increasing depths on movement rates then modeled spline regression. study was conducted in Finland,...
Ungulate–vehicle collisions are intensively studied in many countries. However, limited knowledge exists on how animals struck actually die due to and whether differences traffic mortality occur between species living the same area. In this study, we estimated a kill rate (the proportion of individuals killed/struck) and, relation their winter population sizes, collision rates for four ungulate (moose Alces alces, white-tailed deer Odocoileus virginianus, roe Capreolus capreolus, fallow Dama...
<ja:p>The occurrence of moose damage was studied using data from three National Forest Inventories (NFIs) accomplished between 1986 and 2008 in Finland. The combined included a total 97â390 young stands. proportion increased 3.6% to 8.6% the 8th NFI (1986â1994) 10th (2004â2008). majority (75%) occurred Scots pine-dominated higher aspen-dominated stands than dominated by any other tree species. species mixture also had clear effect on damage. Pure pine less mixed stands, decreased...
Abstract The effects of elevated CO 2 and temperature on the resource allocation pattern resistance against mammalian herbivores silver birch ( Betula pendula Roth) were studied. Birch seedlings grown through two growing seasons in closed‐top chambers exposed to four different treatments: ambient temperature, atmospheric (700 ppm) (+3°C above ambient) , a combination temperature. After winter hardening seedlings, growth was measured concentration secondary compounds such as phenolics...
Large herbivores can have large impacts on their habitats through extensive browsing. Similarly, human actions both and the animals utilizing habitats. In Finland, increase in clear-cut areas has been highly positive for moose particular, because these provide an easy abundant source of winter food. For forest owners, browsing causes growth quality losses or even destruction whole stand. We aimed to identify damage from airborne laser scanning (ALS) data predict damaged areas. The was used...
<ja:p>Traditional timber production may have negative effects on other ecosystem services. Therefore, new forest management guidelines been developed in order to enhance a habitat suitable for wildlife. In Finland, recent example of this is grouse-friendly (GFFM) which emphasises the preservation grouse species (Tetronidae) habitats. This study aimed analyse economic these guidelines. An analysis was made how application GFFM affected Net Present Value (NPV) 30-year simulation four large...
Moose Alces alces is abundant throughout the boreal zone. However, in landscapes occupied by moose density of predators and human influence often vary considerably, as do arrival spring phenology vegetation – all crucial factors for moose, especially during their calving period.During calving, female are faced with a dilemma between choosing habitat offering high quality forage or one protection vulnerable calf. This study examined timing structure after two areas Finland different predator...
Abstract BACKGROUND Moose ( Alces alces L.) populations and moose damage in forests are debated Nordic countries with dense populations. food resources vary greatly, both spatially temporally, reliable data covering variables simultaneously at the same scale have seldom been available. We modelled effect of population density forest on area regional scale, referring to management areas (MMA). Forest originated from Finnish National Inventory, came a Bayesian model. For modelling, average...
The aim of this thesis was to modify and apply a statistical growth yield model for analysing forest resources optimal management under changing climate in Finland.Initially, the structural functional properties physiological models were compared current assess whether could be utilised modification (I).Thereafter, impacts elevated temperature CO 2 on tree introduced into with species-specific transfer functions, which formulated based data simulated (II-III).These functions created...
<ja:p>We modelled the effect of habitat composition and roads on number occurrence moose ( L.) damage in Ostrobothnia Lapland using a zero-inflated count model. Models were developed for 1 km, 25 km 100 landscapes consisting equilateral rectangular grid cells. Count models predict damage, i.e. plantations zero probability landscape being without given composition. The neighboring cells was significant predictor all models. proportion mature forest most frequent variable, an increasing...
