We are currently digitising 75,000 freshwater insects belonging to three small orders. The presence of these groups can give us an idea about the water quality of the river they live in. As August is #WaterQualityMonth we thought this would be a great time shed some light on these orders of insects that you might not have heard much about before.

The Arctic is warming at rates more than twice the global average, and much larger changes are projected for high northern latitudes by the end of this century. In our project we study freshwater microbiology to identify sentinel microbiome properties of northern freshwater environments that can be used to improve surveillance of Arctic ecosystem health in the face of these increasing climate perturbations. The project is funded by funded by a UK-Canadian partnership bursary and in collaboration with researchers from Laval University and Centre for Northern Studies (CEN) – and is part of Sentinel North.
Of particular importance are cyanobacteria, also known as blue-green algae, as they are keystone primary producers, contributors of bioavailable nitrogen, drivers of food webs and carbon cycling in Arctic freshwater ecosystems. However, little is known about their biodiversity in the Canadian Arctic. I therefore, visited Canada this August to carry out field work and collect samples from freshwater environments such as lakes, ponds and streams to carry out DNA sequencing analysis of the freshwater microbiology.
