The British Ecological Society has announced the winners of its annual photography competition, Capturing Ecology. Taken by international ecologists and students, the winning images will be exhibited at the society’s joint annual meeting in Ghent in December.

The photographers had to demonstrate interactions between different species in their natural environments with several different categories, each with an overall winner and a student winner.

Here are some of our favorites.

This year’s overall winner is Christopher Beirne, from the University of Exeter and Crees Foundation, with his image of an ocelot taking advantage of human-made nature trails to stalk its prey in Peru. ‘The photograph was taken in an area of land, which was completely cleared for agriculture 30-50 years ago. Documenting the wildlife that has returned as the forest has recovered was not only a real privilege, it has also changed my perspective on the value of degraded land in tropical areas.’ Photograph: Christopher Beirne/University of Exeter and Crees Foundation/British Ecological Society
