SUMMARY:Soutenance de thèse de Mellina Sidous

Scavenging therefore represents a foraging strategy with net benefits\, which is observed among many vertebrate species when the opportunity arises. Over the past decades\, numerous studies have highlighted the crucial role of scavenging in shaping population dynamics\, predator-prey interactions\, community structure and ecosystem functioning. Despite this\, the importance of scavenging for scavenger species\, and the factors driving its variation over spatio-temporal scales remain poorly understood. Moreover\, the extent to which changes in scavenger communities affect ecosystem functioning\, top-down interactions\, and their long-term consequences on predators and prey populations is unclear. \nThis thesis investigates how scavenger species respond to environmental changes and how these responses influence population dynamics\, predation interactions\, and community structure. Focusing on three contrasting ecosystems—the Serengeti National Park (Tanzania)\, Hwange National Park (Zimbabwe)\, and the Brazilian cerrado—it explores the consequences of key environmental changes. In the Serengeti\, I examined how spotted hyenas adapt to the decline in migratory prey\, their primary resource\, revealing insights into their foraging strategies. In Hwange\, I investigated how pulses of elephant carcasses impact the dynamics between hyenas and their live prey\, shedding on the interplay between scavenging and predation. In the cerrado\, the I assessed how vegetation loss alters scavenger community structure and efficiency\, illustrating the broader implications of habitat changes. The findings emphasize the behavioral flexibility of scavengers and their capacity to adapt to environmental disturbances. At the same time\, they underscore the importance of local ecological contexts in shaping scavenging dynamics and their effects on ecosystems. This research opens new perspectives and highlights the need to assess scavenging rates and the availability of different food sources in future studies.
