“…Release sites should meet the ecological requirements of the species (IUCN/SSC 2013) and promote site fidelity (i.e. tendency of animals to remain near the release site), while reducing mortality during the initial exploratory movements (Ab aigar et al 2020). Lack of site fidelity is associated with higher dispersion distances after release, and consequently higher mortality rates and delays in population growth (Calenge et al 2005;Yott et al 2011).…”

Trophic rewilding is considered a conservation measure that aims to restore the trophic interactions. In north‐central Portugal, the Iberian wolf (Canis lupus signatus) is endangered mainly due to human persecution, triggered by wolf depredation on livestock. Several initiatives have occurred in this area to increase wolf wild prey availability by reintroducing/reinforcing roe deer (Capreolus capreolus) populations. However, the success of trophic rewilding initiatives relies on up‐to‐date scientific evidence, considering both ecological and social settings. Favorability models can be used to infer the most suitable habitats for roe deer settlement and expansion by analyzing the environmental variables known to influence species ecology and behavior. In this study, we infer how the prey habitat favorability can contribute to plan prey populations reinforcement processes as a tool for trophic chain restoration. Using 330 camera traps, we monitored the roe deer population over 8,940 km2 in north‐central Portugal. Field data were used to evaluate the environmental determinants of roe deer presence. By using the favorability function, we created a spatially explicit gradient of habitat favorability that allowed us to define key areas for the application of management measures. The selected sites are strategically positioned to promote the natural expansion of established roe deer populations and overlap the current distribution of Iberian wolf. These results are an important step toward the restoration of the trophic chain and to reduce human–wolf conflicts. Our proposal paves the way for future rewilding initiatives, especially where prey species are central to the survival of top predators.

“…Difficulties in accessing the sand-dominated Saharan habitat along with the declining numbers of animals in the wild have limited the collection of essential empirical data on the ecology of both species. Contrary to other African antelopes such as the mhorr gazelle (Nanger dama mhorr; Abáigar et al 2020) or the gemsbok (Oryx gazella;…”

Contrary to other African antelopes such as the mhorr gazelle ( Nanger dama mhorr ; Abáigar et al 2020) or the gemsbok ( Oryx gazella ; Ruckstuhl and Neuhaus 2009), activity patterns, spatial distributions, and home‐range sizes of the dorcas and slender‐horned gazelles remain largely unknown in their Saharan habitats.…”

“…Reintroduced animals may exhibit behaviors not previously recorded under ex situ conditions and an understanding of the full behavioral repertoire of a species is important to the monitoring, evaluation, and success of reintroduction projects (Rantanen et al 2015). Available ecological data from wild populations is therefore used to evaluate habitat suitability, assess the speed of adaptation to changing environmental conditions, and evaluate behavioral inconsistencies in reintroduced captive‐bred animals (Rantanen et al 2010, Abáigar et al 2020).…”

Saharan ungulates have suffered from poaching across their range leading to population declines. Low abundance and habitat inaccessibility have limited the availability of empirical data on desert ungulate ecology in the wild. Our objective was to evaluate temporal and spatial distribution, and home-range sizes of wild dorcas gazelles (Gazella dorcas) and slenderhorned gazelles (Gazella leptoceros) under natural conditions using observations from 14,398 camera-days collected between April 2019 and October 2021 in the 7,700-ha fenced area of Jbil National Park (Jbil NP), Tunisia. We individually identified gazelles in Jbil NP using unique horn morphology.Both gazelle species exhibited nocturnal activity patterns in summer, but diurnal activity patterns dominated in winter. We also detected both species more frequently in the plains than in mountains. Water presence was influential in determining distribution only for dorcas gazelles. Minimum convex polygons (MCPs) were 2,062 ha for both the male and female of the most frequently detected dorcas gazelle pair and 1,527 ha for another solitary male. For slender-horned gazelles, MCPs were 2,280 ha and 2,041 ha, respectively, for a male and a female detected in Jbil NP. The decline and rarity of gazelles in the Sahara Desert have limited the sample size of our observed populations. Our study provides hitherto unknown data on wild populations of rapidly declining gazelle species and contributes to ongoing conservation efforts.
