Turkey tail fungi are found in mixed-wood forests on every continent except Antarctica. Known as Trametes versicolor to natural scientists, these fungi are admired for the colourful concentric ring pattern on the cap (or ‘pileus’) of their fruiting bodies. These fungi are in the order Polyporales meaning they have multiple openings known as pores under […]

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 […]

Arthropods are a successful group of invertebrate animals; they are members of the phylum Arthropoda, which is known to be the largest phylum in the animal kingdom. The distinguishing feature of Arthropods is the presence of a jointed external skeleton composed of chitin, a nitrogen-containing sugar (Barnes,2014). Furthermore their body is divided into distinct parts, […]

Squirrels are mammals that belong to the Sciuridae family, which is included in order Rodentia (rodent) (Macdonald 2009). They are among the most common and widespread mammals and are found in almost all regions of the world, excluding the arctic, Madagascar and desert areas. These large-eyed, bushy-tailed, diurnal (active during the daytime) animals are relatively […]

Natural History of The walnut trees In North America, some of the most common members of the Juglandaceae family are Juglans cinerea and Juglans nigra, otherwise known as the Butternut or White Walnut and the Black Walnut or American Walnut respectively. These trees are found throughout eastern North America, and prefer deep, moist, fertile soils […]

Welcome fellow salamander enthusiasts! Some of you may already be familiar with our Twitter page (@MacSalamanders), if not, we are a group of four undergraduate students from McGill University (Montreal, QC) conducting a research project on salamanders. Salamanders and newts are amphibians within the Caudata order and belong to the Salamandridae family and Pleurodelinae subfamily, […]

The American Beech Tree The American Beech, by its scientific name Fagus grandifolia, is a deciduous tree native from Nova Scotia. F. grandifolia holds an important role in forestry since its nuts constitute an element of the diet of several species, including humans. Furthermore, due to its hard, heavy and strong wood, Beech trees are […]

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 […]

Salamanders belong to the Caudata order. Along with Anura (frogs) and Gymnophiona (caecilians), they belong to the Amphibian group (Bishop 1943). Salamanders are often confused with lizards because of their similar body form but they lack scales. Instead salamanders have moist glandular skin that is permeable to water and unlike frogs, they have tails and […]

Kingdom : Plantae Order: Sapindales Family: Sapindaceae Genus: Acer Species: A. plantanoides A species native to Europe, the Norway Maple (Acer platanoides) is a deciduous tree now commonly found throughout the St. Lawrence Lowlands, including McGill University’s Morgan Arboretum. In appearance, the Norway Maple is quite similar to other trees of the genus Acer, including […]

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 […]

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 […]

The Northern Woodland White-tailed Deer (Odocoileus virginianus ssp. borealis) is a species of deer found throughout Quebec, including the St. Lawrence Lowland region (Bernhardt et al. n.d.). Its name comes from the white underside of its tail, which can be seen when the deer is alarmed (Rue 2004). Within the St. Lawrence region, white-tailed deer […]

Identification of an American beech tree (Fagus grandifolia): Beech trees can be found in upland areas of a mature deciduous forest. The identification of a beech tree can be done year round with the use of five criteria appearing continually or seasonally: Bark Beech trees stand out by their thin, smooth, grey bark. Leaf The […]

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 […]

Medicinal plants have been used to treat an array of illnesses dating back thousands of years. It is not known exactly who discovered that plants have medicinal properties, but scriptures describing their uses, written around 3000 B.C. by the Egyptians and Ancient Chinese, have been discovered (Ehrlich 2013). Researchers have shown that, throughout time, indigenous cultures […]

Black-capped Chickadees, Poecile atricapillus, are year round songbirds native to North America.3 Their habitat ranges from the Maritimes up to Alaska, covering 2/3 of Northern and Central United States.3,4. Living in flocks of four to twelve birds, Chickadees can be seen in different habitats such as orchards, deciduous and coniferous woodlands, cotton wood groves, parks […]

Acer saccharum, commonly known as the Sugar Maple, is a deciduous tree native to North America. Its genus ‘’acer’’ is latin for maple, and its species name ‘’saccharum’’ comes from the Greek word “sakcaron” meaning ‘’sweet juice distilled from bamboo’’ or simply ‘’sugar’’. (Acer saccharum 2013). This tree is probably most well known because its […]
