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 […]

Hay Scented Fern and its Effect on Sugar Maple Trees in the Morgan Arboretum

Hay Scented Fern and its Effect on Sugar Maple Trees in the Morgan Arboretum

Overview: Hay-scented fern (Dennstaedtia punctilobula) is an invasive, rhizomatous, perennial fern native to North America (Hippensteel and Bowersox, 1995). This species grows in many different conditions and spreads itself by dispersing its spores with the help of wind. This perennial fern is about 1-3’ tall, with deciduous leaves that are erect to ascending. It is […]

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 […]

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 […]

Bird Diversity at the Morgan Arboretum

Bird Diversity at the Morgan Arboretum

Birds come in a wide variety of species, each with its own distinctive colours, calls and behaviours. While some birds’ lifestyles cause them to enter in direct competition with others, such as two species competing for the same nesting sites, other groups may avoid such conflicts by adapting to different food sources and habitats. In […]
