The most defining characteristic of an apex predator is its position at thetop of the food chain. These animals have no natural predators in their habitat, allowing them to play a pivotal role in controlling the population of prey species and maintaining the health of the ecosystem. Many apex ...
Scavenging is an important component to the overall ecology of consumers in virtually all ecosystems on Earth. Given the energetic benefits of foraging on these resource subsidies, opportunistic predators will adjust their behaviors accordingly to maximize access. One of the many consequences of large-...
apex predators1,2,3. Trophic compartments often form in association with distinct habitats, such as rivers, estuaries, nearshore coastal habitats, and offshore pelagic and benthic habitats1,4. Landscapes are mosaics of habitats that are, in turn, composed of microhabitats,...
In the UK and across the world there are plans to reintroduce apex predators and a few of them are presented here. Overall, I conclude that apex predators should be introduced back into our ecosystems but only after sufficient research, planning, and education in the local area. 展开 ...
Demographic differences in resource use are key components of population and species ecology across the animal kingdom. White sharks (Carcharodon carcharias) are migratory, apex predators, which have undergone significant population declines across their range. Understanding their ecology is key to ensuring...

Allosauroid theropods were a diverse and widespread radiation of Jurassic–Cretaceous megapredators. Achieving some of the largest body sizes among theropod dinosaurs, these colossal hunters dominated terrestrial ecosystems until a faunal turnover redefi
“We’re used to thinking of the largest species – blue whales, whale sharks, even elephants and diplodocuses – as filter feeders or herbivores, not predators,” says the paper’s lead author, geoscientist Emma Kast, now based at the University of Cambridge, UK. “But megalodon and the ...
Apex predators were extirpated from the UK hundreds of years ago. Practitioners have recently advocated for reintroductions of predators in the UK given their role as keystone species. For a reintroduction to take place, a survey of public desirability needs to be conducted. We aimed to ...
