Salamanders: their natural history and our research

Salamanders: their natural history and our research

Salamanders belong to the Caudata order. Along with Anura (frogs) and Gymnophiona (caecilians), they belong to the Amphibian group (Bishop 1943).

Research Question In order to to investigate where the Pileated Woodpecker (Dryocopus pileatus) is predominantly found within the Morgan Arboretum and whether they have a preference in area or tree they target, we asked ourselves the following question. “Is the Pileated Woodpecker (Dryocopus pileatus) more active (excavate more trees) in certain parts of the Morgan […]

Coral and Tooth Fungi

Coral and Tooth Fungi

Tooth and coral fungi are both broad categories of taxonomic classification of fungi based on physical characteristics. In fact, years of observations have shown that species in these categories are not necessarily closely related. Coral fungi, or clavarioid fungi, have coral-like elongated structures. They are rather difficult to identify due to the resemblance between many […]

Distributions of earthworms in the Morgan Arboretum

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 […]
