Create AccountEarly land plants have long been known from Eastern Canada, thanks to pioneering work by Sir J. William Dawson, father of Devonian palaeobotany and principal of McGill University from 1855 to 1893. But this record poorly represented the earliest phase of land colonization.
Feathers are only found on birds. They probably evolved as a temperature-control device from scales, much like those of modern reptiles.
The Subarctic covers a relatively large area in eastern Canada; its western counterpart, formed where Pacific and Arctic waters meet and mix, is restricted to a narrow band along the shore of the Beaufort Sea (see Coastal Waters).
Birds of prey could be defined as birds that prey on other living animals; however, the term is usually reserved for species with hooked bills and large, strong, sharp talons.
Sustainability is the ability of the biosphere, or of a certain resource or practice, to persist in a state of balance over the long term. The concept of sustainability also includes things humans can do to preserve such a balance. Sustainable development, for instance, pairs such actions with growth. It aims to meet the needs of the present while ensuring that future people will be able to meet their needs.
Reservoirs, as discussed here, do not include any type of subsurface reservoir structure that stores water, natural gas or oil.
Fishes are members of a large, heterogeneous group of vertebrates living in a wide variety of aquatic habitats.
Animals' lives are circumscribed by 2 imperatives: finding food for survival, growth and reproduction and avoiding becoming prey before reproducing. For an animal to occupy a habitat, it must be able to survive and reproduce within it. Birds have evolved many ways of meeting these challenges.
Canola is a type of rapeseed and is a Canadian invention; it is characterized by having improved nutritional qualities in both the oil and the meal.
Artiodactyla is an order of even-toed mammals that walk on their toenails (unguis). This and the other order of hoofed mammals, the Perissodactyla, are collectively called ungulates.
The wolf is the largest wild member of the dog family. Living wolves belong to the Holarctic species Canis lupus (except red wolf, C. rufus of the southeast US).
Opened in 1992 and located in the former Olympic velodrome, the Montréal Biodôme is part of the “Space for Life” network, which includes Montréal’s Insectarium, Planetarium and Botanical Garden.
The common feature uniting seed plants is the "seed habit," a unique method of sexual reproduction. In all vascular plants, the conspicuous plant is a spore producer (sporophyte) that alternates, in the life cycle, with a sexual phase (gametophyte).
A landslide is a downward and outward movement of a soil mass that formed part of a slope.
During the mid-1970s, a Canadian Wildlife Service researcher discovered that birds in Lake Ontario were behaving in a bizarre way: unable to find mates, pairs of female herring gulls were nesting together and devotedly tending clutches of eggs that usually turned out to be infertile.
Based on geological history, Canada can be divided into six regions, each characterized by a distinctive landscape: the Canadian Shield, Interior Platform, Appalachian Orogen, Innuitian Orogen, Cordillera and Western Canada Sedimentary Basin, and the Eastern Continental Margin.
Animal evolution has resulted in a vast number of adaptations for successful life under all sorts of conditions, so that there are now more kinds of animals than of all other living things combined.
Wheat is the common name for members of genus Triticum of the grass family (Gramineae) and for the cereal grains produced by these grasses.
Resource management usually refers to the responsibility of governments to ensure that natural resources under their jurisdiction are used wisely or conserved.
