Limited mapping of migrations hampers conservation
Summary Natal dispersal is defined as the movement between natal range and site of first breeding one most important processes in population dynamics. The choice an individual makes philopatry may be condition dependent, influenced by either phenotypic attributes and/or environmental factors. Interindividual variability tactics has profound consequences for dynamics, particularly with respect to metapopulation maintenance. A better understanding mechanisms underlying this thus primary...
The way an individual reacts to the risk of predation or disturbance may have important consequences for its immediate and future survival. Risk is likely perceived differently by individuals in relation among-individual differences correlated behavioral traits, that is, syndromes personalities. Given animals can avoid predation/disturbance through modification their habitat use, we might expect differing types adopt contrasting tactics use when faced with risky stressful situations. We...
SUMMARY In wild and domestic animals, gastrointestinal parasites can have significant impacts on host development, condition, health, reproduction longevity. Improving our understanding of the causes consequences individual-level variation in parasite load is therefore prime interest. Here we investigated relationship between strongyle fecal egg count (FEC) body condition a unique, naturalized population horses that has never been exposed to anthelmintic drugs (Sable Island, Nova Scotia,...
When individuals disperse, they modify the physical and social composition of their reproductive environment, potentially impacting fitness. The choice an individual makes between dispersal philopatry is thus critical, hence a better understanding mechanisms involved in decision to leave natal area crucial. We explored how combinations behavioural (exploration, mobility, activity stress response) morphological (body mass) traits measured prior were linked subsequent 77 roe deer Capreolus...
Sea-to-land nutrient transfers can connect marine food webs to those on land, creating a dependence by opportunistic species. We show how nitrogen, imported gray seals, Halichoerus grypus, and traced through stable isotope (δ15 N) measurements in marram grass, Ammophila breviligulata, significantly alters foraging behavior of free-roaming megaherbivore (feral horses, Equus ferus caballus) Sable Island, Canada. Values δ15 N correlated with protein content strongly related pupping-seal...
Parasite abundance has been shown to have major consequences for host fitness components such as survival and reproduction. However, although natal dispersal is a key life history trait, whether an individual's decision disperse or not influenced by the of parasites it carries remains mostly unknown. Current opposing hypotheses suggest that infected individuals should either be philopatric avoid energetic costs (condition dependence) escape from heavily parasitised habitats. From intensive...
Abstract Dispersal is a key mechanism enabling species to adjust their geographic range rapid global change. However, dispersal costly and environmental modifications are likely modify the cost–benefit balance of individual decisions, for example, by decreasing functional connectivity. costs occur during departure, transience settlement, levied in terms energy, risk, time lost opportunity, potentially influencing fitness. best our knowledge, no study has yet quantified energetic across...
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...
Animals perceive human activities as risky and generally respond with fear-induced proactive behaviors to buffer the circadian patterns of lethal nonlethal disturbances, such diel migrations (DMs) between places during safe nighttime safer daytime. However, responses potentially incur costs through movement or reduced foraging time, so individuals should adjust their tolerance when are harmless, habituation. Yet this is a challenging cognitive task risks co-occur, forming complex landscapes...
Evaluating the costs and benefits of dispersal on individual life history is critical to understanding its importance ecology evolution. In feral horses (Equus ferus caballus), females may permanently move among breeding groups (bands) during their lifetime (termed social dispersal). Here, we assess adult female using 7 years movement data from an individual-based study Sable Island. Using path survival analyses, explored relationships between dispersal, reproduction, offspring. Dispersal...
Although inter‐individual heterogeneity in many aspects of dispersal behaviour is widely reported, this key life‐history trait predominantly modelled as a dichotomous state philopatry versus dispersal. The increasing body evidence for syndromes (i.e. suite correlated morphological, behavioural and traits associated with dispersal) implies substantial but, to date, undocumented individual tactics during Using large sample (n = 154) GPS monitored juvenile roe deer Capreolus capreolus , we...
Evolution should favour plasticity in dispersal decisions response to spatial heterogeneity social and environmental contexts. Sex differences individual optimization of are poorly documented mammals, because species where both sexes commonly disperse rare. To elucidate the sex-specific drivers governing dispersal, we investigated sex condition dependence propensity distance natal one such species, roe deer, using fine-scale monitoring 146 GPS-collared juveniles an intensively monitored...
Antipredator behaviours can be lost relatively quickly in populations that are relieved of predation, as is known for several species inhabiting islands. Flight initiation distance (FID) often studied the context island tameness; however, little about factors influence and maintain FID variation predation-free populations. Here, we foals an isolated predator-free population feral horses (Equus caballus L., 1758) on Sable Island, Canada, to determine if could used research consistent...
Abstract Partial migration is common in a large variety of taxa seasonally variable environments. Understanding the mechanisms underlying important, as affects individual fitness. Migratory herbivores benefit from delayed forage maturation and hence higher food quality during at their summer range, termed hypothesis ( FMH ). The link between diet rumination time allows migrants eating to spend less on rumination, they can thus allocate more additional feeding. However, such an argument...
Abstract Accelerometery is revolutionising the field of behavioural ecology through its capacity to detect fine-scale movements animals resulting from their behaviour. Because it often difficult infer behaviour wildlife on a continuous basis, particularly for cryptic species, accelerometers potentially provide powerful tools remote monitoring responses environment. The goal this study was detailed, calibrated methodology, including practical guidelines, free-ranging acceleration data. This...
Abstract Costs associated with reproduction are widely known to play a role in the evolution of reproductive tactics consequences population and eco‐evolutionary dynamics. Evaluating these costs as they pertain species wild remains an important goal evolutionary ecology. Individual heterogeneity, including differences individual quality (i.e., among‐individual traits survival reproduction) or state, variation environmental social conditions can modulate reproduction; however, few studies...
Abstract Ongoing global warming is now affecting migratory cycles in a large variety of taxa seasonally variable environments. Disruption systems can cause population decline and affect ecosystem function across the globe. It therefore urgent to understand drivers migration how different fitness limitations sexes migration, but studies seldom considered full annual cycle. We analysed cycle 237 red deer ( Cervus elaphus ) Norway investigate seasonal affected variation suite characteristics....
