- Abstract: In southern Africa, climate change is increasing drought severity and duration. One way to mitigate drought‐induced food shortages is supplementary feeding, but ungulate responses are largely unstudied. Here, we analyse ~250 h of video footage from camera traps at feeding stations in South Africa during a year when rainfall was ~50% of the decadal average. Feeding station usage was highly uneven: eland ( Taurotragus oryx ), greater kudu ( Tragelaphus strepsiceros ), sable ( Hippotragus niger ) and white rhino ( Ceratotherium simum ) were over‐represented relative to their local population; and impala ( Aepyceros melampus ), blesbok ( Damaliscus dorxas phillipsi ) and zebra ( Equus quagga ) were under‐represented. In total, 81% of individuals at feeding stations fed (0%–90% for different species). Guarding behaviour was observed, especially by eland and kudu, potentially excluding other (smaller) species. Overall, 17% visits involving ≥2 individuals involved intraspecific aggression (highest for sable (40%) and eland (27%); low/absent otherwise); there were very few ( n = 6) inter‐specific encounters. Lucerne and teff hay were consumed more frequently than Boskos (pellets), which was favoured by non‐target primates and ungulates showing guarding behaviour. As benefits of feeding are unequal, and can encourage guarding and intraspecific aggression, we suggest feeding should be done with caution, especially if the aim is to benefit specific species.

Résumé: En Afrique australe, les changements climatiques accentuent la gravité et la durée de la sécheresse. Les programmes d'alimentation supplémentaires constituent un moyen d'atténuer les pénuries alimentaires causées par la sécheresse, mais les réaction des ongulés ne sont généralement pas étudiées. Notre objectif est d'analyser approximativement250 h de séquences vidéo provenant de pièges photographiques installés au sein de stations d'alimentation en Afrique du Sud au cours d'une année pendant laquelle les précipitations étaient approximativement de50 % inférieure à la moyenne décennale. L'utilisation des stations d'alimentation était très inégale : l'éland (Taurotragus oryx), le grand kudu (Tragelaphus strepsiceros), l'antilope noire (Hippotragus niger) et le rhinocéros blanc (Ceratotherium simum) étaient surreprésentés. par rapport à leur population locale, alors que l'impala (Aepyceros melampus), le blesbok (Damaliscus dorxas phillipsi) et le zèbre (Equus quagga) étaient sous‐représentés. Au total, 81 % des individus se sont nourris lorsqu'ils étaient présents aux postes d'alimentation (ce taux varie de 0 % à 90 % pour les autres espèces). Un comportement protecteur a été observé, en particulier chez l'éland et le kudu, excluant potentiellement d'autres espèces (plus petites). Dans l'ensemble, 17 % des visites portant sur ≥2 individus ont impliqué une agression intraspécifique (ce taux était le plus élevé chez l'antilope noire (40 %) et l'élan (27 %); ce taux était faible ou nul dans les autres cas); très peu (n = 6) de rencontres interspécifiques se sont produites. La luzerne et le foin de teff étaient consommés plus fréquemment que le Boskos (granules), qui était l'aliment favori des primates non ciblés. Les ongulés faisant preuve d'un comportement protecteur. Étant donné que les avantages de l'alimentation sont inégaux et peuvent encourager des comportements protecteurs et agressifs intraspécifiques, nous suggérons que l'alimentation soit mise en œuvre avec précaution, en particulier si l'objectif est d'en faire bénéficier des espèces spécifiques. … (more)
