The most common framework under which ungulate migration is studied predicts that it driven by spatio–temporal variation in plant phenology, yet other hypotheses may explain differences within and between species. To disentangle more complex patterns than those based on single species/ populations, we quantified variability using two sympatric species differing their foraging strategy, mating system physiological constraints due to body size. We related observed a set of hypotheses. used...
Deer ( Cervidae ) cause considerable damage to forest plantations, crops, and protected habitats. The most common response this is implement strategies lower population densities. However, lowering deer density may not always be desirable from hunting, recreational, or conservation perspectives. Therefore, knowledge needed about additional factors beyond that affect levels, management actions consider competing goals. We studied the relationships between levels of bark‐stripping by red...
We studied the impact of red fox (Vulpes vulpes) predation on free-ranging roe deer (Capreolus capreolus) neonates during 14 years in a mixed forest/agricultural landscape south central Sweden. A large-scale natural predator removal experiment occurred when an outbreak sarcoptic mange (Sarcoptes scabiei) reduced population initially and caused subsequent variations abundance. estimated relative abundance by dividing number observations with person-days field. Red accounted for 88% known...
Mortality in radio-marked European roe deer (Capreolus capreolus (Linnaeus, 1758)) neonates was studied during 14 years a mixed forestagricultural landscape Sweden. A total of 233 fawns were marked. Births synchronized, with 79% occurring 25 days and peak between May 7 June encompassing 62% the births. Overall mortality 42%, but three single years, it exceeded 85%. Predation by red fox (Vulpes vulpes Desmarest, 1820) accounted for 81% mortality. The effects age, sex, time birth on...
Abstract Red deer are increasing and spreading in Scandinavia. The species is capable of causing severe damage to Norway spruce through bark-stripping. We studied occurrence bark-stripping on 18,000 trees six study areas within two different regions Sweden. susceptibility for was related morphological characters the (bark thickness, branchiness, stem diameter) whether had old or not. In southernmost Sweden, 83, 89 92% stems were damaged three areas, whereas 2, 8 46% region further north....
An understanding of mortality patterns, and especially the variation in juvenile mortality, is an important component vertebrate population dynamics. Our study investigates, for first time, neonate two levels spatial behaviour, a free‐ranging fallow deer Dama dama southwestern Sweden. In summers 2008 2009, 36 fawns were marked with radio‐collars. Neonate calculated by Kaplan‐Meier method was 23.6%. Mortality caused predation low, since only one eight non‐surviving died from predation,...
Abstract Human activity and associated landscape modifications alter the movements of animals with consequences for populations ecosystems worldwide. Species performing long‐distance are thought to be particularly sensitive human impact. Despite increasing anthropogenic pressure, it remains challenging understand predict animals' responses activity. Here we address this knowledge gap using 1206 Global Positioning System movement trajectories 815 individuals from 14 red deer ( Cervus elaphus...
Apex predators may affect mesopredators through intraguild predation and/or supply of carrion from their prey, causing a trade-off between avoidance and attractiveness. We used wildlife triangle snow-tracking data to investigate the abundance red fox (Vulpes vulpes) in relation lynx (Lynx lynx) wolf (Canis lupus) occurrence as well land composition vole (Microtus spp.) density.

Faced with rapid environmental changes, individuals may express different magnitude and plasticity in their response to a given stressor. However, little is known about the causes of variation phenotypic stress wild populations. In present study, we repeatedly captured individual roe deer (Capreolus capreolus) from two populations Sweden exposed differing levels predation pressure measured plasma concentrations stress-induced cortisol behavioral docility. While controlling for marked effects...
Besides red fox Vulpes vulpes predation, mowing is probably the most important mortality factor for roe deer Capreolus capreolus neonates in areas of intensive agriculture. Using radio‐transmitters on south‐central Sweden, I estimated caused by and tested evaluated a traditional method to decrease this kind mortality. During 1997–1999 fawn was at 25–44% yearly recruitment. Fawns were risk least up one month age. The uses scaring devices made plastic sacks that are set out before mowing. idea...
ABSTRACT Deer can show transitional use between agricultural fields and forests for foraging shelter. Such may affect forest damage as nutrient balancing theory suggests that if deer ingest large amounts of nutrient‐rich food, complementary browse, such bark, be required to balance the diet. We investigated relationship level red Cervus elaphus bark‐stripping in 68 Norway spruce Picea abies stands presence rapeseed Brassica napus – an energy‐rich crop preferred by surroundings, hypothesizing...
In the 19th century, red deer (Cervus elaphus) population in Sweden experienced a rapid decline numbers and distribution. A small was, however, remnant southernmost province (Skåne) of country, presumably corresponding to nominate form elaphus Linnaeus, 1758). After management, reintroductions, supplementary release during 20th century Swedish C. recovered. The recovery was partially uncontrolled, included introductions continental origin. northern central (Jämtland) current may stem from...
Context Intraspecific differences in behaviour can affect censuses and bias population estimates, suggesting that choice implementation of census methods are fundamental, need to be adapted behavioural variations. Aims We investigated temporal variations activity patterns during the rut among red deer (Cervus elaphus) categories implications for two different methods. Methods used a long-term dataset collected 17 consecutive rutting seasons southernmost Sweden. The were: (1) collection...
The distribution and population density of red deer (Cervus elaphus) are increasing in several regions Europe. may cause severe damage commercial forestry agriculture. Bark stripping is the main problem forests, especially on Norway spruce (Picea abies), thought to mostly occur during winter when other forage scarce. It has been suggested that an imbalance nutrient intake, a diet including high amounts easily-digestible macronutrients, such as agricultural crops, can lead increased urge...
