Photos of a sinister-looking tree frog, an eagle clutching its prey, and a surprise attack from a hungry mama leopard were all among the finalists in the 2022 British Ecological Society’s annual photography competition, ‘Capturing Ecology’. Snapped by ecologists and students around the world, the winning images celebrate the planet’s diverse flora and fauna.

The top prize this year went to Roberto Garcia Roa, a conservation photographer and evolutionary biologist at Lund University, who captured a captivating shot of a Helena's tree frog (Osteocephalus helenae), its eyes glowing in the gloomy darkness.

"Winning the British Ecological Society’s Capturing Ecology photography competition with this image has a special significance to me for many reasons," Garcia Roa explained in a press release. "First, it links two powerful allies, science, and photography, which have emerged hand in hand during the last two centuries as key tools for deciphering the natural world around us."

Roa went on to stress the importance of protecting threatened species like the Helena's tree frog and its fragile habitats: "This image reveals the beauty of nature hidden in Tambopata, a region that is currently threatened by gold mining."

Also picking up an accolade was Sam Eberhard's photo of a bald eagle carrying its prey among a flock of angry gulls. "'Takeout' is a frozen moment of intense action at Haystack Rock in Cannon Beach, Oregon. A bald eagle has seized a common murre from the top of the rock and is making away with its meal amidst a mobbing of western gulls," says Eberhard, whose image earned him the title of 'Overall student winner of Capturing Ecology 2022'.

Here's a look at some of the other winning and highly commended photos from this year's competition:
