Optimal foraging theory addresses one of the core challenges ecology: predicting distribution and abundance species. Tests hypotheses optimal foraging, however, often focus on a single conceptual model rather than drawing upon collective body theory, precluding generalization. Here we demonstrate links between two established theoretical frameworks animal movements resource use: central‐place density‐dependent habitat selection. Our goal is to better understand how nature critical, centrally...
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...
Abstract Individual‐based study of natural populations allows for accurate and precise estimation fitness components the extent to which they might vary with ecological conditions. By tracking fates all 701 horses known have lived on S able I sland, C anada, from 2009 2013 (where there is no predation, human interference, or interspecific competition food), we present a detailed analysis structured population dynamics focus interacting effects intraspecific weather reproduction survival....
In seasonal environments, the timing of reproduction often matches with peak food resources. One well-known effect global warming is an earlier phenology resources, leading to a possible mismatch between for consumers and peak. However, may also change dynamics such as intensity frequency pulsed mast seeding. How quantitative changes in seeding influence seed remains unexplored. Here, we assess how yearly variation influences mating time wild boar ( Sus scrofa ), widespread consumer species....
For sustainable management of exploited populations, it is required to have good knowledge on temporal trends in population density adapt the harvest. In this regard, hunting statistics are often collected routinely by government agencies and associations. These data used assess demographic through development indices, which turn manage populations a way. However, these indices depend features process (e.g. effort, conditions, probability catch). study, we show how use logs while accounting...
Sympatric populations of species with similar ecology are limited by competition for available resources. While quantifying niche overlap between in interaction offers a useful description coexistence patterns, the lack correspondence and prevents any functional interpretation. Using an innovative approach analysing spatial distributions individuals from two sympatric species, we aim to fill gap. We applied our models data collected on females roe deer red deer. null model commonly community...
Behavioural tactics of animals are determined by both environmental and social factors. Among nonmigratory ungulates, most home-range studies focused either on the effect variables size or overlap between home ranges different individuals. Here, as rarely in previous studies, we aim to identify dynamics range a given individual, involving variation periods, for two resident populations contrasting species: red deer (Cervus elaphus L., 1758) roe (Capreolus capreolus (L., 1758)). In species,...
Hunting can be used as a tool for wildlife management, through limitation of population densities and dissuading game from using sensitive areas. The success these approaches requires in depth knowledge prey movement. Indeed, movement decisions during hunting may affect the killing hunters well subsequent location surviving animals. We thus investigated red deer responses to drive hunts their causal factors. studied 34 events National Estate Chambord (France) thereby provided fine-scale...
Interactions between animal behaviour and the environment are both shaping observed habitat use. Despite importance of inter-specific interactions on use performed by individuals, most previous analyses have focused case studies single species. By focusing two sympatric populations large herbivores with contrasting body size, we went one step beyond studying variation in home range size identifying factors involved such variation, to define how features as resource heterogeneity, quality,...

ABSTRACT Commonly used two‐sex discrete‐time population projection models rely on mating functions developed for continuous‐time frameworks that overestimate the number of unions between reproductive individuals. This has important consequences our understanding evolution and demography populations consequently management conservation. Here, we propose a novel function is robust by obeying all properties necessary to be ecologically valid flexible accommodating systems efficiency in...
