Abstract The media and scientific literature are increasingly reporting an escalation of large carnivore attacks on humans in North America Europe. Although rare compared to human fatalities by other wildlife, the often overplay humans, causing increased fear negative attitudes towards coexisting with conserving these species. populations generally increasing developed countries, numbers not solely responsible for observed rise number carnivores. Here we show that people involved outdoor...
Abstract Large carnivores ( LC s), such as bears U rsidae), are commonly believed to occur near human settlements because they have a learned tolerance of humans (human habituation) and associate with accessible high‐quality foods (food conditioning). Young females cubs often overrepresented among ‘problem’ settlements. We review the mechanisms underlying occurrence brown black rsus arctos , americanus thibetanus ) settlements, consider four hypotheses designed separate ultimate proximate...
Summary Some large carnivore populations are increasing in Europe and North America, minimizing interactions between people carnivores is a major management task. Analysing the effects of human disturbance on wildlife from predator–prey perspective also conservation interest, because individual behavioural responses to perceived risk predation may ultimately influence population distribution demography. The Scandinavian brown bear provides good model study an expanding population, who use...
Abstract The increasing trend of large carnivore attacks on humans not only raises human safety concerns but may also undermine conservation efforts. Although rare, by brown bears Ursus arctos are the rise and, although several studies have addressed this issue at local scales, information is lacking a worldwide scale. Here, we investigated bear (n = 664) between 2000 and 2015 across most range inhabited species: North America 183), Europe 291), East 190). When occurred, half people were...
Human persecution is a major cause of mortality for large carnivores. Consequently, carnivores avoid humans, but may use human-dominated landscapes by being nocturnal and elusive. Behavioral studies indicate that certain ecological systems are "landscapes fear", driven antipredator behavior. Because behavior physiology closely interrelated, physiological assessments provide insight into the behavioral response to human activity. To elucidate changes in brown bears' (Ursus arctos) associated...
Wildlife may adapt activity patterns to daily and seasonal variations in environmental factors human activity. At the scale, diurnal or nocturnal can be a response food availability and/or avoidance. variation prey vulnerability underlies influence of predators on population dynamics, which is management concern when predation affects domestic species. We analyzed movement 133 GPS-collared brown bears three study areas Sweden spring, calves reindeer moose, summer–early fall, rely mostly...
Large carnivores that approach human settlements are usually considered a threat to property and safety. The prevailing paradigm, such 'problem' animals in search of food, ignores their social organization. Based on feces, we compared the diet individual brown bears (Ursus arctos) Sweden relation settlements. Nutritive quality was quantified using near-infrared spectroscopy, food items were identified DNA metabarcoding approach. We analyzed 21 during 36 visits near (<150 m) settlements,...
Successful management has brought the Scandinavian brown bear (Ursus arctos L.) back from brink of extinction, but as population grows and expands probability bear-human encounters increases. More people express concerns about spending time in forest, because possibility encountering bears, acceptance for is decreasing. In this context, reliable information bear's normal behaviour during important. Here we describe bears when humans on foot. During 2006–2009, approached 30 adult (21 females,...
We conducted thirteen immobilizations of previously collared hibernating two- to four-year-old brown bears (Ursus arctos) weighing 21–66 kg in central Sweden winter 2010 and 2011 for comparative physiology research. Here we report, the first time, an effective protocol capture anesthesia free-ranging during hibernation assessment disturbance captures caused. Bears were darted anthill, soil, or uprooted tree dens on eleven occasions, but two rock fled outside den. used medetomidine at...
Human persecution and habitat loss have endangered large carnivore populations worldwide, but some are recovering, exacerbating old conflicts. Carnivores can injure kill people; the most dramatic form of wildlife-human conflict. In Scandinavia, brown bear (Ursus arctos) population increased from ~500 bears in 1977 to ~3300 2008, with an increase injuries, fatalities, public fear attacks. We reviewed media coverage interviewed victims explore how trends, hunter education, other factors may...
Fear of large carnivores such as brown bears may restrict people's outdoor activities regardless experts' estimated risk attack. This research study empirically examined three exposure interventions in the form guided walks intended to give people living bear areas tools for coping with their fear. All significantly reduced fear, decreased perceived vulnerability, and increased social trust wildlife management authorities. The walk including an encounter a radio-collared wild habitat...
The effects of human disturbance spread over virtually all ecosystems and ecological communities on Earth. In this review, we focus the terrestrial apex predators. We summarize their role in nature how they respond to different sources disturbance. Apex predators control prey smaller numerically via behavioral changes avoid predation risk, which turn can affect lower trophic levels. Crucially, reducing population numbers triggering responses are also that causes predators, may influence...
Brown bears (Ursus arctos) in Scandinavia spend 5–7 winter months dens. The denning period is a vulnerable time for because they are unable to escape from disturbances without losing valuable amounts of energy. Bears normally avoid human infrastructure when denning, but due an expanding bear population some den relatively close humans. We tested the hypothesis that closer selected more concealed sites, as do selecting resting sites non-denning season. analyzed horizontal cover and terrain...
Bears foraging near human developments are often presumed to be responding food shortage, but this explanation ignores social factors, in particular despotism bears. We analyzed the age distribution and body condition index (BCI) of shot brown bears relation densities people, whether were killed by managers (i.e., problem bears; n = 149), self-defense (n 51), or hunter-killed nonproblem 1,896) during 1990-2010. compared patterns between areas with (Slovenia) without supplemental feeding...
