The winning photos in this year's "Capturing Ecology" competition

From a resting tree boa backlit by a haze of orange glow to a three-toed sloth edging its way across the tarmac, the winning images in the 2019 British Ecological Society photography competition are both beautiful and eye-opening. Snapped by international ecologists and students, the winning photos serve to celebrate the diversity of flora and fauna from across the planet.

Roberto García Roa, a postdoctoral researcher at the University of Valencia, landed the top prize for his image (above) of a Malagasy tree boa coiled up in an arboreal perch. "Unfortunately, many areas of Madagascar are suffering huge anthropic pressures including poaching and fires, and big snakes are becoming increasingly difficult to see," the photographer explained. "During my visit to Madagascar, I had the pleasure of finding this outstanding snake and photographing it. To offer a dramatic scenario reflecting the conditions that these snakes are suffering, I used an external red light as a source of light and severe blurring to capture the environment."

President of the British Ecological Society (BES), Professor Richard Bardgett called the image "remarkable" adding that it is a "deserving winner."

"This stunning image not only captures the beauty of the Malagasy tree boa, which is endemic to the island of Madagascar, but also its vulnerability, especially to hunting and fire. A remarkable image and deserving winner."

Other winning images featured a white rhino being dehorned (as an anti-poaching measure) and a stunning shot of a male plumbeous water-redstart on the hunt for insect prey.

"The standard of the competition is remarkable, with many outstanding photographs being submitted in 2019," Bardgett said. "Entries this year portrayed the incredible visual diversity of ecology, with images capturing the vibrancy and intimate detail of their subjects. I congratulate all winners and thank all the participants for their submissions."

The winning images will be exhibited at the BES's annual conference in Belfast, between 10 and 13 December, before moving on to the Ulster Museum from 11 February 2020.
