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 […]

Saproxylic Invertebrate Diversity in Decaying Ash Trees Vs. The Stage of Decay

Saproxylic Invertebrate Diversity in Decaying Ash Trees Vs. The Stage of Decay

Trees decay at very slow rates over the space of decades and constitute as much as 10-25% of the above ground biomass in forests (Ulyshen, 2014). Dead wood is a significant factor in nutrient cycling and is a host to many organisms, from unicellular microorganisms to complex invertebrates (Franklin et al., 1997). Organisms that depend […]

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 […]

Follow us on Twitter: @SpidersMcgill Natural History of Spiders Arachnida is an extensive class of arthropods recognized mainly by their eight legs, lack of antennae and carnivorous lifestyle, according to the Encyclopaedia Britannica Online (2015). This class encompasses scorpions, mites, daddy long legs and spiders. Spiders belong to the orderĀ Araneae, which includes over 114 families […]

Fungi and Invertebrates of the Morgan Arboretum

Fungi and Invertebrates of the Morgan Arboretum

Background Fungi are incredibly diverse and provide irreplaceable services for the ecosystem and for us. They range from single-celled yeasts to vast networks of hyphae, the filamentous strands that make up fungi (Waggoner and Speer, 1998). Mushrooms are the fruiting bodies of many fungi; they produce and release spores as a method of reproduction. The […]
