Small Arboreal Mammals of the St. Lawrence Lowlands

Small Arboreal Mammals of the St. Lawrence Lowlands

Small arboreal mammals, such as Eastern Gray Squirrels (Sciurus carolinensis), American Red Squirrels (Tamiasciurus hudsonicus) and Eastern Chipmunks (Tamias striatus), play important roles in forest ecosystems of the St. Lawrence Lowlands, including that of the Ste-Anne-de-Bellevue Morgan Arboretum.

Studying the diversity and ecological importance of aquatic macroinvertebrates

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

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 […]

Eastern Hemlock (Tsuga canadensis)

The eastern hemlock (Tsuga canadensis) is a long-lived coniferous tree native to eastern North America. It is shade tolerant and has a high moisture requirement for establishment.

Litter-Dwelling Arthropods

Litter-Dwelling Arthropods

The Arthropoda phylum accounts for approximately three quarters of the Earth’s organisms (Yi, H. M., Andrew Ralph, 2011), inhabiting both water and land; they are the most diverse of taxa of invertebrates. Arthropods are characterized as having segmented bodies, bilateral symmetry, and exoskeletons made of chitin (Introduction to Phylum Arthropoda, 2012). Litter dwelling arthropods are […]
