The conservation of large carnivores is a formidable challenge for biodiversity conservation. Using data set on the past and current status brown bears ( Ursus arctos ), Eurasian lynx Lynx gray wolves Canis lupus wolverines Gulo gulo ) in European countries, we show that roughly one-third mainland Europe hosts at least one carnivore species, with stable or increasing abundance most cases 21st-century records. reasons this overall success include protective legislation, supportive public...
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database 803 individuals 57 species, we found that mammals in areas with comparatively high human were average one-half to one-third extent their low footprint. We attribute this reduction behavioral changes individual animals exclusion long-range from higher impact. Global loss...
The theory of predation risk effects predicts behavioral responses in prey when is not homogenous space and time. Prey species are often faced with a tradeoff between food safety situations where availability peak the same habitat type. Determining optimal strategy becomes more complex if predators different hunting mode create contrasting landscapes risk, but this has rarely been documented vertebrates. Roe deer southeastern Norway face from lynx, as well by humans. These two differ greatly...
Variation in size of home range is among the most important parameters required for effective conservation and management a species. However, fact that ranges can vary widely within species makes data transfer between study areas difficult. Home Eurasian lynx Lynx by factor 10 different Europe. This aims to try explain this variation terms readily available indices prey density environmental productivity. On an individual scale we related sizes 52 ranges, derived from 23 (9:14 male:female)...
Chemical capture and anaesthesia of free-ranging mammals will always involve some risk mortality even in healthy animals. Deaths may be directly or indirectly attributable to the anaesthetic event itself (e.g. drug overdose, drowning during induction dart trauma) caused by secondary effects from stress, myopathy, trauma instrumentation with radio-transmitters). In long-term research projects on five major wildlife species Scandinavia, capture-related rates (number captures) were: moose Alces...
In the multi‐use landscape of southern Norway, distribution lynx is likely to be determined both by abundance their favoured prey – roe deer and risk associated with presence humans because most mortalities are caused (recreational harvest, poaching, vehicle collisions). We described reproductive portion population based on snow‐track observations females dependent kittens collected over 10 yr (1997–2006) in Norway. used ecological‐niche factor analysis examine how was influenced deer, human...
Summary 1. Understanding the role of predation in shaping dynamics animal communities is a fundamental issue ecological research. Nevertheless, complex nature predator–prey interactions often prevents researchers from modelling them explicitly. 2. By using periodic Leslie–Usher matrices and simulation approach together with parameters obtained long‐term field projects, we reconstructed underlying mechanisms demographic compared roe deer–red fox–Eurasian lynx–human harvest system those...
Summary Environmental conditions shape population growth through their impact on demographic parameters. While knowledge has accumulated concerning the effects of density and climatic conditions, a topical question now concerns how predation harvest influence parameters (λ). We performed comparative analysis based projection matrix models for female roe deer. Population‐specific matrices were parameterized longitudinal data from five intensively monitored populations in Norway France,...
1. Predation plays a major role in shaping the structure and dynamics of ecological communities, functional response predator is crucial importance to any predator-prey system by linking trophic levels. For large mammals, there dearth field studies documenting responses, observations at low prey density are particularly scarce. Furthermore, lack understanding about how variables such as season, social status climate modulate curves. 2. We analysed kill rate data collected over 10-year period...
The re-establishment of large carnivores in Norway has led to increased conflicts and the adoption regional zoning for these predators. When planning future distribution carnivores, it is important consider details their potential habitat tolerances strength inter-specific differentiation. We studied differentiation kill sites within large-carnivore community south-eastern Norway.We compared selection brown bear Ursus arctos L., Eurasian lynx Lynx wolf Canis lupus L. wolverine Gulo gulo...
Habitat selection studies generally assume that animals select habitat and food resources at multiple scales to maximise their fitness. However, sometimes prefer habitats of apparently low quality, especially when considering the costs associated with spatially heterogeneous human disturbance. We used spatial variation in disturbance, its consequences on lynx survival, a direct fitness component, test Hierarchical Selection hypothesis from population Eurasian Lynx southern Norway. Data 46...
Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial temporal resolutions. However, as we enter the golden age of satellite telemetry, need in-depth understanding main technological, species-specific environmental factors that determine success failure tracking across species habitats. Here, assess relative influence such on ability units to provide expected amount quality data by...
Abstract The interaction between predators and their prey is a key factor driving population dynamics shaping wildlife communities. Most will scavenge in addition to killing own prey, which alters predation effects implies that one cannot treat these as independent processes. However, the relative importance of vs. scavenging mechanisms variation such are relatively unstudied ecological research on predator–prey relationships. Foraging decisions facultative likely respond environmental...
The activity patterns of most terrestrial animals are regarded as being primarily influenced by light, although other factors, such sexual cycle and climatic conditions, can modify the underlying patterns. However, studies have been limited to a single study area, which in turn limit variability light conditions factors. Here we considered range variables that might potentially influence large carnivore, Eurasian lynx, network conducted with identical methodology different areas spanning...
Abstract Context Adjustments in habitat use by large carnivores can be a key factor facilitating their coexistence with people shared landscapes. Landscape composition might determining how adapt to occurring alongside humans, yet broad-scale analyses investigating adjustments of across gradients human pressure and landscape are lacking. Objectives Here, we investigate Eurasian lynx ( Lynx ) response varying availability refuge habitats (i.e., forests rugged terrain) modification. Methods...
