Hunting ungulates (mainly deer) or mesopredators rarely limits their populations and may increase it. Poaching creates minor genetic bottlenecks and rapid reduction of small populations, with Swedish wolves for example. How is the new population affected by poaching, hunting and traffic accidents? Australia controls its dingoes, Canis lupus dingo with very strict legalised hunting, while poaching can be even more severe. Permanent reproducing populations now exist in most countries.

As well as the wolf rewilding, bear and lynx have recovered and the golden jackal has spread from SE Europe. This European increase in large carnivores is remarkable. Further south, in Germany, large human populations create mosaics of divers land usage for the wolves to rewild! Empty parts of Sweden have intense activity in the form of forestry, combined with the highest recorded hunting pressures on ungulate prey animals by the carnivores. Europe is smaller, has dense human populations and has been intensively modified for thousands of years by domestic animals and plants and their owners. The aim of the paper is to present ways of predicting various outcomes because prey behaviour, for example, is affected even by low densities of predators.Īpex predators in North American National Parks have a vital function in that semi-natural environment. Kuijpe of the Polish Academy of Sciences in Białowiez and his colleagues from Sweden, North Carolina State University, US, the Norwegian Polar Institute, CNRS-Universite de Montpellier-Universite, France and the Nelson Mandela Metropolitan University in South Africa publish Their paws without claws paper in the Proceedings of the Royal Society B today. With rewilding and many other modern tests of urban man and woman, large carnivores are saviours of the ecosystem, maintaining the food chains in, a trophic cascade. The Europeans on this paper do not neglect the North American or Asian examples of anthropogenic effects, while many parts of the world have different carnivores in similar situations in both cities and almost pristine natural environments that need careful study.

Their prey, their territory size, their total ecological function is affected, both directly, and also in devious ways. Human action alters the habitat to which many carnivores have been adjusted. The wolves who approach people where our populations are dense are providing experiments to test how effective their predation can be where their natural habitat is highly modified by human impacts.īears, leopards and even tigers can also impinge on our own environments, which of course, used to be theirs. The lynx may soon be reintroduced into Scotland, northern England or even the Netherlands, while parts of Europe and North America already have plenty of lynxes, than you very much!
