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...
Filarioid parasites represent major health hazards with important medical, veterinary, and economic implications, considerable potential to affect the everyday lives of tens millions people globally (World Health Organization, 2007). Scenarios for climate change vary latitudinally regionally involve direct indirect linkages increasing temperature dissemination, amplification, invasiveness vector-borne parasites. High latitude regions are especially influenced by global thus may be prone...
Transmissible spongiform encephalopathies or prion diseases comprise with different levels of contagiousness under natural conditions. The hypothesis has been raised that the chronic wasting disease (CWD) cases detected in Nordic moose ( Alces alces ) may be less contagious, not contagious between live animals field This study aims to investigate epidemiology CWD Norway, Sweden and Finland using surveillance data from 2016 2022. In total, 18 were moose. All positive for (PrP res detection...
Elevations of carbon dioxide, temperature and ultraviolet-B (UBV) radiation in the growth environment may have a high impact on accumulation plants, different factors work opposite directions or induce additive effects. To detect changes phytochemistry silver birch (Betula pendula) seedlings, six genotypes were exposed to combinations ambient elevated levels CO2 , UVB top-closed chambers for 7 weeks. The relatively similar their responses, no significant interactive effects three-level...
Phenology can have a profound effect on growth and climatic adaptability of northern tree species. Although the large interannual variations in dates bud burst termination been widely discussed, little is known about genotypic spatial phenology how these sources variation are related to temporal variation. We measured eight white birch (Betula pendula Roth) clones two field experiments daily over 6 years, determined for same 2 years. also yearly height growth. found considerable genetic...
Individuals, free to choose between different habitat patches, should settle among them such that fitness is equalized. Alternatives this ideal distribution result into differences the patches. The concordance fitnesses and foraging costs inhabitants of quality demonstrated in recent studies, suggests mode selection resulting patterns may have important implications resource use a forager survival its prey. We studied how coarse scale patches quitting harvest rate these are related each...
Abstract We studied the ability of tree seedlings to respond two environmental factors, elevated ultraviolet B (UVB) radiation and availability nitrogen (N), at beginning their development. Seeds birch species, Betula pubescens Ehrh. (common white birch) B. pendula Roth (silver birch), were germinated grown in an experimental field eastern Finland. The design consisted a constant 50% increase UVB (including slight UVA), UVA control (a UVA) control. fertilized with three levels N. experiment...
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 The effects of enhanced UVB radiation and drought stress on willow secondary phenolics were studied using the leaves 8‐week‐old micropropagated plantlets from interspecific hybrids ( Salix myrsinites L. × S. myrsinifolia Salisb.) pure species myrsinifolia) . subjected for 4 weeks to two levels (ambient, enhanced) watering (well‐watered, drought‐stressed) according a 2 factorial design. Enhanced increased total concentration flavonoids phenolic acids in all plantlets, while...
Partial migration, whereby a proportion of population migrates between distinct seasonal ranges, is common throughout the animal kingdom. However, studies linking existing theoretical models migration probability, with empirical data are lacking. The competitive release hypothesis for partial predicts that due to density‐dependent habitat selection, migrants increases as relative quality and size range increases, but decreases increasing cost density. To test this prediction, we developed...
Predators may control the impact of herbivores on their plant resources by 1) decreasing herbivore numbers, 2) imposing predation risk affecting foraging behavior. The goal present study was to examine effects a predator and auditory cues indicating its presence rate tree seedling ( Acer rubrum , Betula lenta ) consumption meadow voles Microtus pennsylvanicus ). first our experiments involved introduction stoat Mustela erminea into an enclosed vole population second playback recordings...
• Elevated carbon dioxide (CO2), temperature (T) and ultraviolet-B (UV-B) radiation may affect plant growth secondary chemistry in different directions, but the effect of combination three factors has seldom been tested. Here, we grew four dark-leaved willow (Salix myrsinifolia) clones under combinations ambient or elevated CO2, T UV-B top-closed chambers for 7 wk. had no effects on phenolic compounds, there were significant interactions between UV-B, CO2 T. alone increased most parameters,...
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,...
