instaGrok.com biome Canada's Endangered Species 256 Canadian species are listed by the Scientific Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as being extinct, extirpated, endangered, threatened and vulnerable. The list only includes Canada's vertebrate and vascular plant species and was released in April 1994. Definitions are: Extinct - a species formerly indigenous to Canada that no longer exists anywhere. Extirpated - a species no longer existing in the wild in Canada but occurring elsewhere in the world. Endangered - a species threatened with imminent extinction or extirpation throughout all or a significant portion of its Canadian range. Threatened - a species likely to become endangered in Canada if the factors affecting its vulnerability are not reversed. Vulnerable - a species particularly at risk because of low or declining numbers, small range or for some other reason, but not a threatened species. Extinct - 9 species Mammals, 2; Birds, 3; Fish, 4 Extirpated - 11 species Endangered - 55 species Plants, 30;
MBGnet Species at Risk in Nova Scotia NS Endangered Species Act: Legally Listed Species The following species at risk are legally protected under the NS Endangered Species Act. Included for each species is the year it was listed under the Act, the status category, a brief explanation of why it was listed, and a link to "Additional Information" on recovery efforts. Please note that species are assessed each year and therefore the list of species at risk protected under the act is updated annually. The up to date list of species can also be viewed at Regulations under the Nova Scotia Endangered Species Act. Species are listed by status category: • Endangered | • Threatened | • Vulnerable | • Extirpated | • Extinct
The world's biomes Online exhibits The world's biomes Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (Campbell 1996). The importance of biomes cannot be overestimated. Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Here we group biomes into six major types: Conservation and preservation of biomes Because we share the world with many other species of plants and animals, we must consider the consequences of our actions. Forests are important as they are home to the most diverse biotic communties in the world. Logging has depleted many old-growth temperate forests. Tropical forests have fallen victim to timber exploitation, slash and burn farming, and clearfelling for industrial use or cattle ranching, particularly in Latin America.
Research Tools The world's biomes Biomes A biome is a large, distinctive complex of plant communities created and maintained by climate. How many biomes are there? A study published in 1999 concluded that there are 150 different "ecoregions" in North America alone. But I shall cast my lot with the "lumpers" rather than the "splitters" and lump these into 8 biomes: The figure shows the distribution of these 8 biomes around the world. A number of climatic factors interact in the creation and maintenance of a biome. whether it ever freezes; length of the growing season If there is ample rainfall, we find 4 characteristic biomes as we proceed from the tropics (high temperatures) to the extreme latitudes (low temperatures). Tropical Rain Forest In the Western Hemisphere, the tropical rain forest reaches its fullest development in the jungles of Central and South America. The tropical rain forest exceeds all the other biomes in the diversity of its animals as well as plants. Temperate Deciduous Forest Taiga The photo (courtesy of Dr.

Characteristics of the Earth's Terrestrial Biomes 9(k) Characteristics of the Earth's Terrestrial Biomes Introduction Many places on Earth share similar climatic conditions despite being found in geographically different areas. As a result of natural selection, comparable ecosystems have developed in these separated areas. Scientists call these major ecosystem types biomes. The geographical distribution (and productivity) of the various biomes is controlled primarily by the climatic variables precipitation and temperature. The map in Figure 9k-1 describes the geographical locations of the eight major biomes of the world. Most of the classified biomes are identified by the dominant plants found in their communities. The diversity of animal life and subdominant plant forms characteristic of each biome is generally controlled by abiotic environmental conditions and the productivity of the dominant vegetation. Adaptation and niche specialization are nicely demonstrated in the biome concept. Arctic and Alpine Tundra Tundra means marshy plain. Boreal Coniferous Forest Temperate Deciduous Forest
