#WaterWednesday - Brook Floaters The Brook Floater (Alasmidonta varicosa) is a freshwater mussel species listed as Special Concern under the Species at Risk Act (SARA). Brook Floaters are distributed across northeastern North America from Georgia to the southern half of New Brunswick and central Nova Scotia. This mussel has disappeared from approximately half of its USA locations; therefore, the Canadian population represents an important global stronghold for the species. Th...e second picture shows Brook Floaters filter feeding in the Petitcodiac Watershed. What a great shot from Darlene Elward at the Petitcodiac Watershed Alliance/ Alliance du bassin versant Petitcodiac ! #mussels #freshwater #waterresearch #CRIresearch #CRI #MAES

#WaterWednesday - Stoneflies Stonefly nymphs live in streams and rivers for 1-3 years, and then they crawl onto land and moult into their adult form, living only for 1-4 weeks. Stonefly nymphs are one of the most pollution-sensitive orders of aquatic insects (along with caddisflies and mayflies), so they are commonly used as biological indicators of aquatic ecosystem health. #stonefly #insect #streamhealth #CABIN #biomonitoring #streamecology #freshwaterecology #diversity

#WaterWednesday - Autumn leaves Why do deciduous trees change colour during autumn? Deciduous leaves are green during the spring and summer seasons because they are producing a green pigment (chlorophyll) through a process called photosynthesis. As the days become shorter and colder, the leaves stop photosynthesizing and the green pigment breaks down and fades. Other pigments that are different colours become more visible, which is why we see more reds, oranges, and yellows.... Most of the leaves will fall off trees in late autumn. The leaves that fall into freshwater bodies are a great source of nutrients for the ecosystem, and they can even form habitats for small organisms, such as benthic macroinvertebrates. #autumn #autumncolours #autumnleaves #fallcolours

We honour those who have served Canada, past and present, in times of war, military conflict and peace. This year marks the 75th anniversary of the end of the Second World War. This bitter conflict raged for six years and saw over one million brave Canadians serve in uniform around the globe. #HonourVeterans
