Special Issue Information

Dear Colleagues,

Decline in species populations can be partially or totally due to predation, which can be caused by invasive and native species, and is sometimes driven by human activities such as habitat destruction and fragmentation or unintentional food supplementation of predators. Recently, a new discipline called "coexistence conservation" has been proposed within conservation science, which brings together recent innovations and concepts to address the coexistence of predators and threatened prey through the development of non-lethal measures. This new approach aims to promote the adaptation of threatened fauna through the use of innovative tactics based on evolutionary processes that aim for the long-term coexistence between predators and prey by either reducing the predation of predators (through e.g., conditioned taste aversion, chemical camouflage, odour repellence, Automated Behavioural Response (ABR) systems, aversive conditioning) or by improving the adaptation of prey species to coexist with its predators (through e.g., animal pre-conditioning, in situ adaptation, targeted gene flow).

The aim of this Special Issue is to bring together the latest findings concerning the innovative tools and field experiments that address predation control by using methods that do not use the control of predator populations. Original research papers, as well as literature reviews from different research areas, such as biological conservation, wildlife management, animal translocation, policy, invasive species, animal welfare and animal behaviour with a link to prey management and conservation are also invited. Papers on additional topics and interdisciplinary studies regarding the effects of human activities that modulate or affect the predator–prey relationship and compare the effectiveness of lethal and non-lethal methods will also be considered.

The current range of the jaguar (Panthera onca) spans sixty degrees of latitude across eighteen countries in the Western Hemisphere and covers approximately 7,000,000 km2. Throughout this geographical breadth, jaguars represent an essential component of native biological diversity, but conflict revolving around real and perceived jaguar depredation on livestock is a factor in jaguar mortality. We developed a structured questionnaire to evaluate the effectiveness of anti-depredation strategies from northern Mexico to Argentina, collecting data from 11 countries and 248 livestock operations, 194 with efficacy metrics, and 24 with benefit–cost ratios (value of the livestock losses averted/cost of the intervention). Using coarse categories, 11 intervention types were tested. Techniques effectively reducing livestock losses were documented across the entire livestock operation size (2–130,000 ha, 5–30,000 head) and biome spectrum. While the techniques varied in complexity and required levels of investment, successful reductions in depredation were achieved at all levels. We conclude that anti-depredation strategies are highly effective, and when benefits are evaluated, they surpass costs, sometimes substantially. Given the proven efficacy and cost-effectiveness of the techniques described in this paper, we advocate for broader application across the species range to increase tolerance towards jaguars and a more effective human–jaguar coexistence.
