Photos of flies, fish, snakes, seabirds, a decapitated butterfly and even a decaying zebra have been recognised in the British Ecological Society's annual photo competition.
More than 200 entries were received - a new record for the competition - showing scenes of the natural world spanning Africa, Asia, the Americas and Europe.
The winning shot was taken in a back garden in Sweden by Alejandro Ruete, a PhD student at the Swedish University of Agricultural Sciences. He called his photo, which shows a hoverfly perched delicately on a globe thistle, "Kiss in the backyard".
"This is a tiny example of the ecology that is going on in our backyards," Mr Ruete said.
"A whole variety of species population dynamics and interactions can be found in a not-so-well-kept garden (like mine) while fostering the presence of native pollinators."
The overall runner-up was a photo taken by Benjamin Blonder, from the University of Arizona, of isolated vegetation in the stark environment of Death Valley, California.
The competition is open to all members of British Ecological Society (BES) and the judges included their fellow ecologists, BES staff and BBC Wildlife Magazine's picture editor, Wanda Sowry.
The winning images in various categories are now on show at a joint meeting between the BES and the Societe Francaise d'Ecologie (SFE) in Lille, France.
