Can compensatory culling offset undesirable evolutionary consequences of trophy hunting?
1. There is growing concern about the evolutionary consequences of human harvesting on phenotypic trait quality in wild populations. Undesirable consequences are especially likely with trophy hunting because of its strong bias for specific phenotypic trait values, such as large antlers in cervids and horns in bovids. Selective hunting can cause a decline in a trophy trait over time if it is her...
متن کاملIncentivizing Monitoring and Compliance in Trophy Hunting
Conservation scientists are increasingly focusing on the drivers of human behavior and on the implications of various sources of uncertainty for management decision making. Trophy hunting has been suggested as a conservation tool because it gives economic value to wildlife, but recent examples show that overharvesting is a substantial problem and that data limitations are rife. We use a case st...
متن کاملBanning Trophy Hunting Will Exacerbate Biodiversity Loss.
International pressure to ban trophy hunting is increasing. However, we argue that trophy hunting can be an important conservation tool, provided it can be done in a controlled manner to benefit biodiversity conservation and local people. Where political and governance structures are adequate, trophy hunting can help address the ongoing loss of species.
متن کاملCan profits and lions co-exist?: The case of trophy-hunting in Tanzania
Concerns about the management of threatened species continue to grow as these populations face mounting pressures from many factors. Trophy hunting in particular plays a significant role in wildlife conservation, both economically and biologically. In this paper, we present a framework for analyzing the economic impacts of different management strategies in the context of legal lion hunting in ...
متن کاملWhat Enables Size-Selective Trophy Hunting of Wildlife?
Although rarely considered predators, wildlife hunters can function as important ecological and evolutionary agents. In part, their influence relates to targeting of large reproductive adults within prey populations. Despite known impacts of size-selective harvests, however, we know little about what enables hunters to kill these older, rarer, and presumably more wary individuals. In other mamm...
