The image above by Kristen Brown shows a school of jackfish swimming in a spiral at the Great Barrier Reef. It was the overall winner in the <a href="https://bmcecolevol.biomedcentral.com/articles/10.1186/s12862-021-01886-7" class="on">2021 photo competition from the scientific journal BMC Ecology and Evolution</a>. The picture also won in the category Conservation Biology. <blockquote>The competition attracted entries from researchers all around the world eager to use their creativity to highlight their work and capture the diversity of the planet's flora and fauna. BMC Ecology and Evolution invited anyone affiliated with a research institution to submit to one of the following six categories: ‘Conservation Biology', 'Evolutionary Developmental Biology and Biodiversity', 'Behavioural Ecology', 'Human Evolution and Ecology', ‘Population Ecology' and 'Ecological Developmental Biology'. Our Senior Editorial Board Members lent their expertise to judge the entrants to the competition, selecting the overall winner, runner up and best image from each category. The board members considered the scientific story behind the photos submitted in addition to their artistic judgement (Fig. 1). </blockquote>#jackfish #fish #biology #photography #photocompetition

The winner in the Evolutionary Developmental Biology and Biodiversity category, and overall runner-up, is from Kseniya Vereshchagina. It shows a crustacean in Lake Baikal in Siberia suffering from a parasitic ciliate infection. #crustacean #LakeBaikal #Siberia #shrimp #parasite #ciliate

Roberto García-Roa took a picture of a wasp devouring a spider in Ecuador, and won the Behavioral Ecology category. #wasp #spider #animalbehavior
