Ecological data often show temporal, spatial, hierarchical (random effects), or phylogenetic structure. Modern statistical approaches are increasingly accounting for such dependencies. However, when performing cross‐validation, these structures regularly ignored, resulting in serious underestimation of predictive error. One cause the poor performance uncorrected (random) noted by modellers, dependence that persist as model residuals, violating assumption independence. Even more concerning,...
Background Human disturbance can influence wildlife behaviour, which have implications for populations. For example, may be more vigilant near human disturbance, resulting in decreased forage intake and reduced reproductive success. We measured the effects of activities compared to predator other environmental factors on behaviour elk (Cervus elaphus Linnaeus 1758) a human-dominated landscape Alberta, Canada. Methodology/Principal Findings collected year-round behavioural data across range...
Among agents of selection that shape phenotypic traits in animals, humans can cause more rapid changes than many natural factors. Studies have focused on human morphological traits, but little is known about behavioural traits. By monitoring elk ( Cervus elaphus ) with satellite telemetry, we tested whether individuals harvested by hunters adopted less favourable behaviours survived the hunting season. 45 2-year-old males, showed bolder behaviour, including higher movement rate and increased...
ABSTRACT Aim We aimed to describe the large‐scale patterns in population density of roe deer Caprelous capreolus Europe and determine factors shaping variation their abundance. Location Europe. Methods collated data on from 72 localities spanning 25° latitude 48° longitude analysed them relation a range environmental factors: vegetation productivity (approximated by fraction photosynthetically active radiation) forest cover as proxies for food supply, winter severity, summer drought presence...
Long-term tracking using global positioning systems (GPS) is widely used to study vertebrate movement ecology, including fine-scale habitat selection as well large-scale migrations. These data have the potential provide much more information about behavior and ecology of wild vertebrates: here we explore GPS datasets assess timing activity in a chronobiological context. We compared two different populations deer (Cervus elaphus), one Netherlands (red deer), other Canada (elk). were calculate...
Abstract This study investigated the anti‐predator strategies adopted by 19 radio‐collared female roe deer during fawning season monitoring their spatial behaviour and habitat selection means of radio‐tracking. The was carried out in a forest area Apennine Mountains (central Italy), where wolves are natural predators summer fawns more frequently predated than adult deer. presence monitored direct observations. Roe known to adopt hiding strategy lactation period, when they lie concealed for...
Humans, as super predators, can have strong effects on wildlife behaviour, including profound modifications of diel activity patterns. Subsequent to the return large carnivores human-modified ecosystems, many prey species adjusted their spatial behaviour contrasting landscapes fear generated by both natural predators and anthropogenic pressures. The predation risk temporal shifts in prey, however, remain largely unexplored human-dominated landscapes. We investigated influence density lynx...
In animal behaviour, there is a dichotomy between innate behaviours (e.g., temperament or personality traits) versus those shaped by learning. Innate traits are supposedly less evident in animals when confounded learning acquired with experience through time. Learning might play key role the development and adoption of successful anti-predator strategies, related adaptation has potential to make that more experienced vulnerable predation. We carried out study system involving large...
The artificial selection of traits in wildlife populations through hunting and fishing has been well documented. However, despite their rising popularity, the role that may play non-extractive activities, for example, recreational feeding remains unknown. If only a subset population takes advantage human-wildlife interactions, if this results different fitness advantages these individuals, then be at work. We have tested hypothesis using wild fallow deer living edge capital city as our model...
Abstract Home‐range sizes and habitat selection among calving non‐calving female fallow deer Dama dama were analysed during the last months of pregnancy following parturition. The study was carried out in central Italy using radio‐tracking techniques. It based on data collected 23 adult females (calving n =15, =8) from March 2003 to August 2003. Seasonal bimonthly home‐range analyses showed marked differential spatial behaviour between only when fawns present. These born June, summer...
Abstract Migrations of large ungulates are globally threatened in environments affected by increasing human disturbance, rising carnivore predation, deteriorating habitat quality, and changing climate. Animals migrating outside protected areas can be exposed to greater pressure, this effect stronger when humans perceived a predation risk, such as during hunting seasons. Using four consecutive years satellite telemetry data ( n = 138 migration events), we compared selection, movement,...
Dispersal has a critical influence on demography and gene flow as such maintaining connectivity between populations is an essential element of modern conservation. Advances in satellite radiotelemetry are providing new opportunities to document dispersal, which previously been difficult study. This type data also can be used empirical basis for defining landscapes terms resistance surfaces, enabling habitat corridors identified. However, despite the scale-dependent nature selection few...
Abstract Avoiding hyperthermia entails considerable metabolic costs for endotherms. Such increase in warm conditions, when endotherms may trade food intake cooler areas to avoid heat stress and maximize their energy balance. The need reduce involve the adoption of tactics affecting space use foraging behaviour, which are important understand predict effects climate change inform conservation. We used resource selection models examine behavioural response Alpine ibex ( Capra ), a cold-adapted...
Restricting movements to familiar areas should increase individual fitness as it provides animals with information about the spatial distribution of resources and predation risk. While benefits familiarity for locating have been reported previously, potential value avoidance has accorded less attention. It suggested that be beneficial anti-predator behaviour when direct cues risk are unclear do not allow prey identify well-defined refuges. However, our knowledge, this hypothesis yet tested....
Abstract Independent human–wildlife feeding interactions (i.e., the of wildlife by public outside organized ecotourism activities) represent an increasingly common way in which humans and are engaging with one another. It is important to determine what effects these having on involved order ensure that optimum coexistence scenarios being achieved, however nature makes them notoriously difficult study. Extrapolation from activities has suggested detrimental impacts health fecundity...
