Studying the diversity and ecological importance of aquatic macroinvertebrates

When one looks out on the St. Lawrence waterway, they normally see large container ships passing by. However, the traffic below the surface is far greater, as it is teeming with life. Although they constitute a large part of this underwater community, aquatic macroinvertebrates are often overlooked. Despite this, they represent a key link between […]

Bracket Fungi

One of the most challenging aspects of studying the natural history of bracket fungi is to define exactly what one includes in this grouping. Bracket fungi is a commonly known classification, but since it is based upon the fungi’s pattern of growth as opposed to genetics and evolutionary history, there is a lot of gray […]
