Dispersal influences distribution and genetic structure of animal populations. in expanding wolf (Canis lupus) populations is not well documented, especially Europe, where no studies dispersal based on marked wolves are available. We studied the Finland, a peripheral population (160– 180 animals) increased expanded during 1998–2004. equipped 60 from 8 neighboring pack territories with radio or GPS transmitters east-central Finland 1998–2004, at least 30 (50%) dispersed home territory....
The air interface of the UMTS Terrestrial Radio Access (UTRA) covers both a frequency division duplex (FDD) part for paired bands and time (TDD) unpaired spectrum. Universal Mobile Telecommunication System (UMTS) is 3rd-generation mobile communication system. This paper presents an interference evaluation UTRA TDD. Since uplink downlink share same in TDD, signals two transmission directions can interfere with each other. occur between stations or base within one carrier operators. evaluated...
Abstract It is generally accepted that predation by wolves Canis lupus one of the major factors limiting densities woodland caribou Rangifer tarandus in North America. Conversely, little known about role European wild forest reindeer R. t. fennicus as wolf prey, or influence on populations this rare subspecies. This relationship was examined east‐central Finland, where coexist with moose Alces alces at a numerical ratio c . 1 to 1.5 moose. During study, were clearly primary prey wolves....
The estimation of large carnivore populations presents major logistical challenges. We examined trends in the wolf Canis lupus population Finland using two independent methods. compared track indices from an annual wildlife winter census based on a constant, nationwide network transect lines (wildlife triangles) with number reproductions confirmed to occur same year during 1996 2009. Nationwide, and eastern management zone, which is core area Finnish wolves, frequency tracks triangles (% all...
The habitat selection criteria of moose Alces alces at several scales are the basic sets information needed in management planning. We studied use central Finland during 1993–1996 using data from radio collared moose, satellite image based forest and land cover data, applied principles compositional analysis. compositions 54 home ranges (10 males summer, six winter, 23 females summer 15 winter) were first compared with overall landscape. around locations within their then composition range....
ABSTRACT The isolated gray wolf ( Canis lupus ) population of the Scandinavian Peninsular is suffering from inbreeding depression. We studied dispersal 35 wolves fitted with very high frequency (20) or Global Positioning System—global system for mobile (15) radiocollars in neighboring Finnish population. growing Finland has numbers dispersing individuals that could potentially disperse into About half (53%) moved total distances have reached if they had been straight‐line moves, but because...
Artificial food supplementation of wildlife is an increasing practice for species conservation, as well hunting and viewing tourism. Yet, our understanding the implications supplementary feeding still very limited. Concerns have been raised over potential negative impact artificial feeding, but effects this on animal movements rhythms activity are just beginning to be investigated. Here, with aim studying whether brown bears may affect their behaviour, we analysed (1) probability intensity...
Abstract The Eurasian golden jackal ( Canis aureus ) has been rapidly expanding its distribution range in Europe. Whether jackals will be able to adapt new environmental conditions northern Europe remains largely unresolved. Herein we provide additional evidence for the species’ ability colonize environments by presenting records of occurrence Finland. During 2018–2022, were recorded at six localities which one located southern, four central and We drafted potential main routes dispersal...
Abstract During the reproductive period, mating strategies are a significant driver of adaptations in animal behaviour. For instance, for polygamous species, greater movement rates during season may be advantageous due to increased probability encountering several potential mates. The brown bear Ursus arctos is solitary carnivore that lives at low densities, with system and an extended nearly 3 months. Here, we hypothesized male bears show changes patterns space‐use behaviour their season....
ABSTRACT Biotic interactions are expected to influence species' responses global changes, but they rarely considered across broad spatial extents. Abiotic factors thought operate at larger scales, while biotic factors, such as species interactions, more important local scales within communities, in part because of the knowledge gap on large (i.e., Eltonian shortfall). We assessed, a continental scale, (i) importance through food webs, distributions, and (ii) how under scenarios climate...
We examined wolf Canis lupus attacks on domestic dogs C. familiaris in six Finnish territories occupied by mated pairs and packs. Most incidents (76%, N = 21 confirmed cases) took place inside one territory. The wolves mostly (70%) attacked house yards. It appeared that the territory were actively seeking for rather than killing them as a result of random encounters. A strong tendency to attack seemed be adopted pups born pack. did not find evidence density primary prey or resident...
The practice of feeding brown bears Ursus arctos for recreational purposes is common in the easternmost areas Finland, but this may, however, result human‐habituated bears. From 1995 to 2008, 3% all killed by humans (N = 1,108 bears) Finland represented incidents where were either reasons human safety under a license issued police or as actual emergency situations shot self defence. We constructed binary logistic regression models comparing and defence with regular sport hunting using sex...
Managers are sometimes faced with a situation where one endangered species increases the vulnerability of another one. According to our late-winter helicopter survey Finland's two small populations wild-forest reindeer (Rangifer tarandus fennicus), eastern decreased by half during last 7 years. This is probably due return wolf (Canis lupus) area. Our data show that annual recruitment rate strongly correlated density. Calf mortality was high and stable first months after birth. The classified...
Infanticide is a significant evolutionary force influencing carnivore behaviours, as it one of the primary contributors to offspring mortality. Female multimale mating, which creates paternal uncertainty, known reduce infanticide. We propose that two crucial steps are needed for this strategy work in solitary species like brown bears, Ursus arctos. First, after females should choose dens within their mating area (step 1), boosting chances encountering potential fathers cub(s) den emergence...

Reliable and updated population estimates are a necessity for the successful conservation management of endangered animal populations. Citizen science has become increasingly important in wildlife monitoring is an attractive concept due to its low costs. However, applicability citizen large carnivore populations questionable various reasons, including difficulties associated with species identification. In Finland, where fragmentary wolf (Canis lupus) have varied between 140 280 animals last...
ABSTRACT Biotic interactions are expected to influence species’ responses climate change, but they usually not included when predicting future range shifts. We assessed the importance of biotic understand consequences and land use change for biodiversity using as a model system brown bear ( Ursus arctos ) in Europe. By including spatial variation energy contribution habitat models each food species, we showed that factors considerably improves our understanding distribution bears. Predicted...
Adjacent channel interference in the UTRA-TDD system has been investigated. The problem was approached statistically and a computer simulation model generated. impacts of four different instances, MS/spl rarr/BS, BS/spl rarr/MS rarr/MS, were considered depending on frame synchronisation. flexibility base station location analysed with respect to varying load cells causing interference. consequences adjacent found be fairly severe. Synchronisation have less impact performance than unplanned stations.
Movement patterns may reflect individual age-specific variation. For example, individuals that sample novel areas (e.g. natal dispersal) show different movements from those of adults settling in more stable and moving around local environments to procure food shelter. The long-term study a solitary large carnivore, the brown bear, Ursus arctos, allowed us test for age-related differences movement behaviour and, specifically, potential inter- versus intraindividual variation among adult...
