“…Grazing levels are not too high on either heath type despite high overall population densities of approximately 1 deer per ha. Our study agrees with previous findings [52] and show that this is because sika deer use dry heaths and other habitats more than wet heaths. The grazing by C. nippon creates open ground for ants and stimulates fresh growth of the larval food plant, whether that is E. tetralix (in wet heath plots), or C. vulgaris (in dry heath plots).…”

“…Accordingly, the foraging area size decreased with legume availability in both sexes. A decrease in foraging area as food availability increases has been found in other species (Schradin et al, 2010;Uzal et al, 2013). Besides the legume availability effect on the size of morning foraging area, there could be a food distribution effect on animal mobility.…”

“…The area in which an animal lives and performs activities associated with foraging, social behaviours and resting is known as its home range (Burt, 1943). Its size has been shown to be influenced by many factors, such as food availability (Schradin et al, 2010;Uzal et al, 2013), body size (McNab, 1963;Jenkins et al, 1981;Belovsky & Slade, 1986;Lindstedt et al, 1986;Mysterud et al, 2001), sex (Mysterud et al, 2001;Dunbar & Shi, 2008;Pays & Jarman, 2008;Lees et al, 2012), age (Mikesic & Drickamer, 1992;Tufto et al, 1996), diet (McNab, 1963) and brood size (Säid et al, 2005). Among these factors, body size and food availability have been identified as the main determinants of home range size, which correlates positively with body size and inversely with food availability (McNab, 1963;Schoener, 1968;Peters, 1983;Jetz et al, 2004;Tamburello et al, 2015), both between species (Haskell et al, 2002) and within species (e.g., Cederlund & Sand, 1994;Palomares, 1994).…”

Food Availability But Not Sex Determines Morning Foraging Area Size in the Great Bustard Otis tarda, the Most Sexually Size-Dimorphic Bird Species

Sexual size dimorphism (SSD) may favour physiological peculiarities in diet, behaviour and home-range size both across species and within species. Sex-specific differences in diet and behaviour have been reported in several bird species but there are fewer studies of foraging area size in sexually dimorphic bird species. Foraging area size should be greater in the bigger sex according to home-range size predictions based on body mass. We tested this prediction in a winter study of foraging area size in the Great Bustard Otis tarda, the most sexually size-dimorphic bird species, which forages in unisexual flocks. In this species the temporal pattern of a flock's feeding intensity; the proportion of birds actively feeding (FI) and the size of the morning foraging area (MFA) of each sex are unknown. We recorded the behaviour and movements of unisexual flocks of Great Bustards during winter mornings and sampled food availability to take into account its effect on FI and MFA. FI increased and then decreased through the morning in both sexes, and was lower in males than in females. This sexual difference was greater where legume availability was smaller. Legumes were the most preferred substrate type. Consequently, MFA sizes were smaller in sites with more legume availability. We did not find sexual differences either in the size of MFA or in the selection of the two preferred substrate types: legumes and stubble fields. MFA and FI were determined to a greater extent by ecological factors such as food availability than by metabolic requirements derived from body size differences. These results obtained from a short-term study do not preclude an effect of sexual size dimorphism

“…Thus, the outcome of inter-specific competition may provide an alternative explanation to the observed patterns. Indeed, when selecting the habitat with the highest food biomass (i.e., shrubs and pole stage), female roe deer might try to decrease the competition for food resources with red deer 29 while eventually benefiting from cover to protect them from hunters 30 , 31 . Such selection for habitat offering cover in areas where animals are heavily harvested is also a common tactic allowing individuals to protect themselves from hunters 16 , 30 , 32 .…”

Same habitat types but different use: evidence of context-dependent habitat selection in roe deer across populations

With the surge of GPS-technology, many studies uncovered space use of mobile animals and shed light on the underlying behavioral mechanisms of habitat selection. Habitat selection and variation in either occurrence or strength of functional responses (i.e. how selection changes with availability) have given new insight into such mechanisms within populations in different ecosystems. However, linking variation in habitat selection to site-specific conditions in different populations facing contrasting environmental conditions but the same habitat type has not yet been investigated. We aimed to fill this knowledge gap by comparing within-home range habitat selection across 61 female roe deer (Capreolus capreolus) during the most critical life history stage in three study areas showing the same habitat types but with different environmental conditions. Female roe deer markedly differed in habitat selection within their home range, both within and among populations. Females facing poor environmental conditions clearly displayed a functional response, whereas females facing rich environmental conditions did not show any functional response. These results demonstrate how the use of a given habitat relative to its availability strongly varies in response to environmental conditions. Our findings highlight that the same habitat composition can lead to very different habitat selection processes across contrasted environments.
