The earth is divided climatically and geographically into specific areas where there are similarities in communities of vegetation, organisms and animals. These ecosystems are often referred to as biomes. Differences in biomes usually consists of identifiable plant structures where there is a specific pattern of ecological activity. Biomes are also major types of habitats for different types of organisms and animals.
The following paper will explore two different biomes: Boreal Forest and the Tropical Rainforest. An examination of these two biomes will provide an understanding of how these biomes exists and the various types and forms of processes that acted on it and are acting on it both biologically and through abiotic factors.
Named after Boreas, the Greek God of the North Wind, the Boreal Forest Circles the northern globe like an emerald halo. At 1.2 billion acres, Canada’s intact boreal forest stretches from coast to coast and it is the largest intact forest ecosystem remaining on earth (Kurz, Stinson & Rampley, 2008). This unique and protected mosaic of interconnected habitat includes lakes, river valleys, wetlands, peatlands and tundra, at its northern regions (Kurz, Stinson & Rampley, 2008). Its rich soils and permafrost store twice as much carbon per acre as tropical rainforests and are critical in the fight against global warming (Preston, Bhatti, Flanagan & Norris, 2006).
At a time when fresh water supplies are diminishing around the globe, the vast reserves in Canada’s boreal are increasingly important to protect. Wetlands make up nearly one third of the Canadian boreal, an estimated 1.5 million lakes and some of the country’s largest river systems (Soja, et al., 2007). Canada’s largest river, the McKinsey, has sustained indigenous people for thousands of years and it is critical to maintaining Arctic currents (Soja, et al., 2007). Canada’s Great Bear Lake is the largest pristine lake in the world (Soja, et al., 2007). Hundreds of Aboriginal communities in the boreal rely heavily on waterfowl, beaver, fish, and aquatic species for food. They also use lakes and rivers as transportation where no roads exist (Soja, et al., 2007).
Canada’s boreal is home to bear, caribou, wolves and other large migratory animals that still roam this vast landscape, including the George River caribou herd (Preston, Bhatti, Flanagan & Norris, 2006). The Boreal is also the nesting ground for billions of migratory birds, more than 300 specie (Preston, Bhatti, Flanagan & Norris, 2006)s. The Peace-Athabasca Delta is one of the most important ecological places on the planet. It has been designated as a world heritage site and a wetland of international importance (Soja, et al., 2007). All for flyways of North America aerial migration routes traveled by billions of birds each year converge in the delta (Soja, et al., 2007). More than one million birds including tundra swans, snow geese, countless ducks and the endangered whooping crane...
