    Tahltan Bear Dog

    The Tahltan (pronounced tall-tan) bear dog was one of five dog breeds recognized by the Canadian Kennel Club as uniquely Canadian (see also Dogs in Canada). Although the name of the breed suggests it was only kept by the Tahltan Nation of Northwestern British Columbia, the dog was common among other First Nations in the region, too. These included the Tlingit, Tagish, Kaska and Sekani. The Tahltan people referred to it as “our dog,” which gave the breed its name. Indigenous peoples used the Tahltan bear dog in sustenance hunting— primarily for bear— an activity in which it excelled. The breed went extinct in the in the 1970s or 80s.

    Tick

    Ticks are small, bloodsucking arachnids that live as external parasites on terrestrial mammals, birds, amphibians and reptiles. Ticks belong to the order Ixodida, a group of parasitic mites in the superorder Parasitiformes. This superorder also includes the varroa mite, a destructive parasite of honeybees. About 900 tick species are known worldwide, of which 48 have been found in Canada. Although they are most diverse in tropical regions, ticks continue to be significant pests to humans and other mammals as far north as the Canadian tundra.

    Tidal Energy

    Tidal energy is a largely untapped, renewable energy source based largely on lunar gravitation. While the potential of tidal hydroelectricity has long been recognized, compared to river dams, tidal power projects are expensive because massive structures must be built in difficult saltwater environments.

    Tide

    The Earth is actually not in orbit around the sun but around the centre of mass of the Earth-sun system. Since all parts of the Earth move in the same orbit, they experience the same acceleration, but only at the Earth's centre is this acceleration exactly balanced by the sun's gravitation.

    Tiktaalik

    Tiktaalik is a genus of lobe-finned (sarcopterygian) fish from the Devonian Period found on Ellesmere Island, Nunavut, in Canada’s Arctic Archipelago. A single species is known of Tiktaalik, T. roseae, which lived approximately 385 million years ago. The species was named in 2006 in two articles that described several articulated specimens. These articles set off a storm in the popular press. Titkaalik represents a clear and important evolutionary step in the journey of animals onto land.
