Earthworm Abundance in Relation to Buckthorn
St. Lawrence lowland forests are home to an immense amount of diversity. However, this diversity can sometimes be put in danger with the introduction of invasive species. Invasive species are attributed to being the second leading cause of local extinction (Roth et al., 2015). One major invasive species in North American forests is the common […]
Leaf Litter Invertebrates of the Morgan Arboretum
Invertebrates, while small, play an integral role in our ecosystem in the St. Lawrence Lowlands. In leaf litter, they aid greatly in the decomposition of organic matter, as cited by Vasconcelos and Laurance in their article on soil fauna (2005). Invertebrates are animals that lack a backbone, but this is where most of the obvious […]
The Abundance of Earthworms with Human Activity
Introduction We are McGill university undergrad students studying environmental biology. In the course St. Lawrence Ecosystem (ENVB 222), we will be conducting a research project geared at evaluating earthworm abundance in the Morgan Arboretum. To expand on the data collected by researchers in last year’s class, we chose to further study earthworms, but in relation […]
Distributions of earthworms in the Morgan Arboretum
With earthworms getting more attention as they make their way into once earthworm-free forests, it was surprising to find that there had been no past research done on the distribution of earthworms in the Morgan Arboretum. Due to the limited amount of time, we took this opportunity to target the St.Bernard soil series (one of […]
