Reptile

Reptiles are a group of vertebrate animals that, like mammals, produce an amniote egg, with extra-embryonic sacs for waste, yolk, and protection, and often possessing a shell, particularly if released by the female before development of the embryo is completed.

Cultivated Flowers

Flowers are cultivated by both commercial growers and hobbyists. In Canada, most commercial production is carried out under glass or plastic, with rare exceptions.

Soil Classification

Classification involves arranging individual units with similar characteristics into groups. Soils do not occur as discrete entities; thus the unit of measurement for soil is not obvious.

Skunk

 The skunk is a carnivorous, cat-sized mammal. Skunks were previously considered as part of the weasel family (Mustelidae) but DNA research has placed them in their own family, Mephitidae.

Chromium

Chromium (Cr) a hard, brittle, silver-white metal (melting point 1875° C), is widely known for its use as decorative trim on home appliances and automobiles. However, its most important use is in the manufacture of stainless STEEL, which typically contains about 20% chromium.

Annelida

Annelids are mostly vermiform (worm-shaped), with an anterior (frontal) mouth preceded only by the prostomium, bearing sensory organs; the anus is posterior. Most have bristles (chaetae or setae), usually arranged in 4 groups on each segment.

Midge

Midges are small, slender-bodied flies with long antennae, belonging to various families. Three families are especially important: non-biting midges (Chironomidae), biting midges (Ceratopogonidae, also called no-see-ums), and gall midges (Cecidomyiidae). In Canada, there are more than 1,300 named species of midges from these groups, and scientists expect at least as many more live here. The larvae of most non-biting and biting midges are aquatic, while most larval gall midges live and feed inside of growths on plant tissues. Midges are found all across Canada and in a variety of habitats.

Hydroelectricity in Canada

Hydroelectricity is energy produced from flowing water. The amount of energy produced depends on volume and speed: the more water moving at a fast rate, the more energy produced. For this reason, many hydroelectric stations are built near waterfalls. To produce energy, water is directed toward turbines — sometimes with the help of a dam — causing them to spin. In turn, the turbines make electrical generators spin and electricity is produced. It is a renewable, comparatively nonpolluting energy source and Canada’s largest source of electric-power generation.

Cod Moratorium of 1992

On 2 July 1992, the federal government banned cod fishing along Canada’s east coast. This moratorium ended nearly five centuries of cod fishing in Newfoundland and Labrador. Cod had played a central role in the province’s economy and culture.

The aim of the policy was to help restore cod stocks that had been depleted due to overfishing. Today, the cod population remains too low to support a full-scale fishery. For this reason, the ban is still largely in place.

Meteors, Meteorites and Impact Craters

The solar system contains many objects smaller than the planets (or their satellites) travelling in individual orbits about the SUN; space between the planets also contains myriad dust grains in the micron size range. Near Earth, dust concentrations are only a few hundred particles per cubic kilometre, but 35 000 to 100 000 t of extraterrestrial material enters the atmosphere annually, swept up by our planet from debris that is in its path or crosses its path.

Sustainability in Canada

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.

Black Fly

Black flies are small, dark-coloured insects belonging to the family Simuliidae. Of the world’s more than 2,300 species, at least 164 are found in Canada. Black flies reproduce in streams and are found all across Canada. They are particularly common in northern temperate and subarctic regions. Because female black flies need to feed on blood to lay eggs, their biting can be a nuisance to humans and other animals. Among the most common and notorious black flies in Canada are Simulium truncatum and Simulium venustum.
