A keystone species is a plant or animal that plays a unique and (1)crucial role in the way an ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. A small number of keystone species can have a huge impact on the environment. A keystone species is often a predator.

Forests in wetter regions are more productive owing to warming. Shifts in species ranges are so extensive that by 2100 they may alter biome composition across 5-20% of US land area. Accelerated losses of nutrients from terrestrial ecosystems to receiving waters are caused by both winter warming and intensification of the hydrologic cycle. Beyond the core areas and connecting corridors lies another area with land selected for sustainable use with preservation of several ecosystem functions. What is the purpose of ecological corridors? Corridors help maintain or recover a certain degree of cohesion in otherwise fragmented ecosystems.

Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated fashion. Some of the more important components are: soil , atmosphere , radiation from the Sun , water , and living organisms . The leaves also act as natural filters of air and water by removing particulate matter. A very important function of trees in the growing concrete-based world is in flood control. The roots hold soil in place, which would otherwise be washed away in heavy rains. Trees also act as natural barriers to the weather elements such as wind and snow. Classification of Ecosystem: Ecosystems can be broadly divided into two main categories as terrestrial and aquatic ecosystems. Major terrestrial or land ecosystems include grasslands, forests and deserts etc while major aquatic ecosystems includes ponds, lakes, rivers, estuaries, oceans, coastal and inland wetlands etc.

The ecosystem is the most complex level of biological organization. The ecosystems of the world are distributed in environmentally controlled patterns or biomes , which contain distinctive communities with similar life forms (but not necessarily the same species) across broad geographic areas. The Function of the Ecosystem The primary function of any ecosystem is the exchange of energy from one life form to others, which eventually runs in a circle and sustains the entire life of the planet. Without the ecosystems maintaining balance, there would not have been any life form existing on earth. Important Ecological Concepts

To carry out their various functions, ecosystems also need access to materials—the nutrients referred to above. Unlike energy, which can only flow through an ecosystem, nutrients can be utilized repeatedly. Through biogeochemical cycles, nutrients are recycled from dead biomass, through inorganic forms, back into living organisms, and so on. Mangrove forests are among the most productive ecosystems on earth, and serve many important functions, including water filtration, prevention of coastal erosion, coastal protection from storms, carbon storage, food, timber, and livelihood provision, and biodiversity protection, among others.

ABSTRACT. Forests are among the most important ecosystems that provide various hydrological services including water production and protection because the vast majority of the water available on the earth comes from forested catchments. The forests provide quality and continuous water yield as well as protective services such as flood control, soil protection, landslide protection, avalanche protection, and prevention against rock falls, which are related to water.
