The Relationship Between Forest Type and Amphibian Abundance

Follow the twitter account @nofibs4amphibs to learn more and see fun updates on the research project! Introduction Amphibians are cold-blooded vertebrates who undergo fascinating metamorphoses. Once upon a time, they were the top land predators from the Carboniferous to early Permian (Carroll 2009). A diverse group, they occupy many niches and play an invaluable role […]

Species Richness of Ascomycota in the Morgan Arboretum

Fungi are a highly diverse kingdom of organisms, ranging from microscopic yeasts to the world’s largest living organism, the honey fungus, whose fruiting bodies can span across nearly 4 km of land (Fleming, N. 2014). At first glance, many fungi seem to bear a significant resemblance to members of the plant kingdom, while in actual […]

Human Impact on the Invertebrate Diversity in the Grasslands of the Morgan Arboretum

Invertebrates and Human Impact What would happen if invertebrates disappeared? It is a question one might have never pondered, for invertebrates by their small size and unpopular status, are often ignored. In short, it would be catastrophic. Invertebrates provide many essential ecosystem services and impact us in many ways. Ecosystem services are defined as the […]

Earthworm Abundance in Relation to Buckthorn

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 […]

Invertebrate Abundance and Diversity in Ponds

Invertebrate Abundance and Diversity in Ponds

Invertebrates are a diverse group of cold-blooded organisms that do not have or develop a backbone at any stage of their lives (Buchsbaum, Milne, 1960). They are so diverse in their structure, physiology, habitat, and behavior that they constitute approximately 95% of the total identified animal species on earth. With over 30 phyla, they are […]

Buckthorn Abundance Along Edge Habitats: Morgan Arboretum

  Figure 1: One of the tree lines we studied, on a beautiful day. Introduction: The invasive European shrub known as Buckthorn, has been recently identified as detrimental to North American ecosystems (Mascoro, 2007). There are two types, Common buckthorn (Rhamnus cathartica) and Glossy buckthorn (Fragula alnus) (See figure 2). In the context of our […]

Feeding Habits of The Eastern Grey Squirrel in Urban and Forest Habitats

Feeding Habits of The Eastern Grey Squirrel in Urban and Forest Habitats

Squirrels are one of the most recognizable animals in Canada. According to The Natural History of Squirrels (Gurnell 1987), three different types of squirrels exist: flying, ground-dwelling and tree squirrels. They all evolved from a common ancestor living in North America during the Eocene epoch (54 to 57 Million years ago), and then spread out, […]
