Various species of wild, adaptable, medium-sized carnivores occur outside of protected areas, often coming into contact with people and their domestic animals. Negative human-carnivore interactions can lead to antagonistic attitudes and behavior directed at such species. In the South African Karoo, a semi-arid rangeland, the predation of small-live...

Rewilding is a growing conservation concept that seeks to enhance biodiversity and improve ecosystem functioning. When rewilding includes the reintroduction of large carnivores to landscapes from which they have been extirpated, assessing the societal impacts and acceptability is as, if not more, important than assessing the ecological feasibility...
Article
Despite the importance of disease as a wildlife management challenge in South Africa, baseline data on the epidemiology of pathogens occurring in free-ranging species has received little attention to date. Black-backed jackals (Canis mesomelas) are a wide-ranging, abundant carnivore with substantial economic importance due to their role in livestoc...

Thirty years after the return of grey wolves (Canis lupus) to the French Alps, the number of livestock losses is on the rise despite livestock guarding dogs (LGDs) being widely used. Their relevance is, therefore, questioned by some sheep owner associations. To date, no study has investigated how LGDs interact with wolves in pastures. We present th...
Article
The use of livestock guarding dogs (LGDs) has been widely advocated as a responsible tool for reducing livestock predation and conserving wildlife. However, their hidden ecological costs have rarely been investigated. We analysed scats (n = 183) from six LGDs and visited Global Positioning System (GPS) location clusters (n = 352) from nine GPS-coll...

Background: Wild carnivores living alongside humans and domestic animals are vulnerable to changes in the infectious disease dynamics in their populations. The aims of this study were to determine the prevalence and diversity of selected tick-borne pathogens (TBPs) of veterinary and/or zoonotic concern in wild populations of caracals (Caracal cara...
Article
The black‐backed jackal Canis mesomelas, henceforth jackal, has re‐emerged as a threat to South African sheep farmers. This sparked contestation between farmers and conservationists over the reasons for their return and the relative merits of lethal and non‐lethal approaches to protecting livestock. Three separate reviews of the scientific literatu...
Article
Populations of adaptable mesopredators are expanding globally where passive rewilding and natural recolonization are taking place, increasing the risk of conflict with remaining livestock farmers. We analysed data from two social surveys of farmers in the Karoo, South Africa, where black-backed jackals (Canis mesomelas) and caracals (Caracal caraca...
Conference Paper
Introducing consumptive and non-consumptive effects into food webs can have profound effects on individuals, populations and communities. Consequently, the deliberate use of predation and/or fear of predation is an emerging technique for controlling wildlife. Many now advocate for the intentional use of large carnivores and livestock guardian dogs...
Article
Studying the feeding ecology of mesopredators living on or adjacent to farmland is important as livestock predation fuels conflict between farmers and predators and between diverse stakeholders on how to best manage this conflict. Most dietary studies on elusive and heavily persecuted predators rely on indirect methods such as scat analysis, becaus...

Global distributions of most terrestrial large mammals have been dramatically reduced through the loss and fragmentation of natural habitat. These impacts are likely to be intensified by the effects of global climate change. Here we use two free roaming leopard (Panthera pardus) populations to explore the intersecting influences of climatic conditi...

Extensive farming is an important source of food and fibre and often the only viable land use in the more arid regions of the globe. Yet, land use transformation for livestock grazing can lead to natural habitat degradation and fragmentation, identified as the main threats to biodiversity worldwide. Understanding which species are “winners” (i.e. s...

Article
Conflict between predators and small-livestock farmers is a global phenomenon adversely impacting the preservation of wildlife, the well-being of livestock and human livelihoods. Such conflict is pervasive in the Karoo region of South Africa but its contemporary history and various causes remain poorly understood. In this study, we interviewed 77 s...

Globally, several carnivore species have been implicated as livestock predators, these ranging in body size from the mongoose (Herpestidae) (e.g. Minnie, 2009) to the tiger Panthera tigris (Gusset, Swarner, Mponwane, Keletile & McNutt, 2009; Van der Merwe, Avenant & Lues, 2009a) and bears (e.g. Li, Buzzard, Chen & Jiang, 2013). However, medium-size...

Predators have considerable impacts on ecosystems and biodiversity, with many recent studies highlighting their strong top-down effects that influence ecosystem structure and function. The majority of these insights come from studies on a handful of large charismatic predators (i.e. lions Panthera leo: referred to as apex predators when these large...
Conference Paper
Full-text available
Livestock predation is a pervasive form of human-wildlife conflict on rangelands, particularly in semi-arid regions of Africa where livestock farming is extensive and numerous species of carnivore still occur outside of protected areas. In the Karoo drylands of South Africa, black-backed jackal (Canis mesomelas, hereafter jackal) were the scourge o...
Conference Paper
There is a debate in South Africa over how best to prevent predation of small livestock by black-backed jackal (Canis mesomelas). When black-backed jackals re-emerged in the 1990s and 2000s as a serious predator on sheep farms in South Africa’s dry interior Karoo, many farmers resorted to lethal control. Conservation authorities warned that culling...
Article
Full-text available
Jackals (Canis mesomelas) and caracals (Caracal caracal) are considered major predators of small livestock on farms across South Africa, with both species being subjected to lethal control. Lethal management (i.e., culling) can result in differential responses in the population dynamics and demography of mesopredators. We examined the potential imp...

The use of land for pastoralism is often associated with a reduction in the diversity and abundance of wildlife and influences conflict between farmers and predators worldwide. We explored differences in the diversity and relative abundance of medium and large animals on farmlands and a nearby protected area and compared these differences to prey c...
Conference Paper
Full-text available
Livestock depredation by carnivores is on the rise worldwide and is one of the key conservation issues in arid landscapes with low abundance of wild prey. To mitigate such a conflict, understanding its drivers is the first step conservationists should undertake. In South Africa, extensive conflict between small-livestock farmers and caracals (Carac...

Caracals are widespread within the assessment region. They are considered highly adaptable and, within their distribution area, are found in virtually all habitats except the driest part of the Namib. They also tolerate high levels of human activity, and persist in most small stock areas in southern Africa, despite continuously high levels of perse...

The Black-backed Jackal is endemic to sub-Saharan Africa and is widespread. It is considered a generalist canid with an opportunistic lifestyle and occupies most habitats within the assessment region. Black-backed Jackals are the dominant predators of livestock in the assessment region and are thus widely persecuted in an attempt to reduce populati...

Bill-wiping, or the scraping by a bird of its bill along a substrate, has been observed in social contexts and cited as an irrelevant displacement activity. However, several behaviors once categorized as displacement behaviors have since been shown to serve adaptive functions. Here, we hypothesize that bill-wiping may function in social interaction...

The study of animal communication has been dominated by a focus on signal types that are easily recognized and quantified by human observers. This approach has inevitably limited our ability to identify cryptic signals such as low-amplitude vocalizations and signals that transmit beyond the range of our sensory system, such as most olfactory signal...

Project
In France, the lynx populations currently occur within three mountain massifs, the Jura (~110 individuals), the Alps (~20 individuals), and the Vosges (<10 individuals). These small populations are fragmented and all descend from the few individuals that were reintroduced in Switzerland in the 70’s. That strongly suggests an overall low genetic diversity (as reported for the Swiss populations), which could impair their viability. The aim of the LYNX project is to develop a method to analyse the genetic structure of the French lynx populations by using a set of microsatellites in scats collected in the wild. Our consortium involves the Department Chrono-Environment (University of Franche-Comté/National Research Centre CNRS), the French Society for the conservation and study of Mammals (SFEPM), a regional nature park (Parc Naturel Régional du Haut-Jura), two national nature reserves (Réserve Naturelle Nationale de la haute-chaîne du Jura and RNN des Hauts de Chartreuse), three NGOs (Pôle Grands Prédateurs, Observatoire des Carnivores Sauvages, wildlife care centre Athénas) and several independent naturalists and lynx experts, all skilled in lynx observation and monitoring. We would like to share great thanks to the funders of the LYNX project, i.e., the LTER Arc Jurassien (https://zaaj.univ-fcomte.fr/), the Zoo de la Garenne (https://www.lagarenne.ch/) and the Nature & Découvertes foundation (https://fondation.natureetdecouvertes.com/).
