    Blue Whale

    The blue whale (Balaenoptera musculus) is the largest animal known to have ever lived on Earth. It is a difficult whale to study because of its low numbers and its preference for deep, offshore waters. Within Balaenoptera musculus, authorities recognize between three and five subspecies. Blue whales live in oceans throughout the world, including off the Atlantic and Pacific coasts of Canada. Although blue whale sightings are rare, experts believe that about 250 mature individuals live off each coast.

    Blueberry

    Blueberries are a group of shrubs in the genus Vaccinium that bear edible blue, black or purple berries. The berries can be consumed fresh, frozen or dried. Their taste and health benefits contribute to their importance as an agricultural crop. Different blueberry species and cultivars are grown across Canada. Vaccinium is a cosmopolitan genus (i.e., with species found across the world) and is only absent from Australia and Antarctica. There are approximately 480 species, but only a limited number are thought of as blueberries. They are closely related to a few other edible Vaccinium species, including cranberries, lingonberries, huckleberries and grouseberries. Black- and blue-fruited huckleberries and bilberries are also often considered blueberries and are included here. Like other plants in the heath family (Ericaceae), blueberries naturally grow in acidic, often boggy soils, where other kinds of plants often struggle to extract sufficient nutrition. Across North America, Europe and Asia, there are at least 30 Vaccinium species that could be classified as blueberries. In Canada, that number is around a dozen. Most North American blueberries are deciduous shrubs, though there are a few evergreens. The deciduous leaves of blueberries are renowned for their brilliant orange to scarlet autumn colour.

    Boreal Zone

    The boreal zone is Canada’s largest vegetation zone, making up 55 per cent of the country’s land mass. It extends from Yukon and northern British Columbia in the west to Newfoundland and Labrador in the east. While much of the region is covered by forest, it also includes lakes, rivers, wetlands and naturally treeless areas. The boreal zone is home to diverse wildlife, and is crucial to maintaining biological diversity, storing carbon, purifying air and water, and regulating the climate. With more than 2.5 million Canadians living in the boreal zone, the forest also provides these rural communities with jobs and economic stability.

    Boundaries

    The political boundaries that are of concern to Canada today are the international boundaries primarily with the US and Greenland and, because they are of more than local importance, the boundaries of the provinces and territories. The evolution of both types involved 2 distinct stages. After political decisions were made on the allocation of territory, such territories were delimited and the boundaries described in state documents. Then, usually some time later, the boundaries were surveyed and marked on the ground (the process of demarcation).

    Bowhead Whale

    The bowhead whale (Balaena mysticetus) is a large baleen whale living in Arctic waters. Two populations are found in Canada: the Bering-Chukchi-Beaufort Sea population and the Eastern Canada-West Greenland population. During the summer, the Bering-Chukchi-Beaufort Sea population is found in the waters of the Yukon and the Northwest Territories, while the Eastern Canada-West Greenland population is found in Davis Strait, Baffin Bay, Lancaster Sound, Hudson Strait, Foxe Basin, northwest Hudson Bay and the channels and fjords of the Arctic Archipelago. Commercial whaling began in the 1500s and ended around 1915. Both populations of bowhead whale were severely reduced by this industry. While their numbers have increased, other challenges, such as climate change and oil and gas development, pose threats to bowhead whales.
