Even though no one theory can explain all factors able to control succession, some variables appear to be more important compared to others (Wright, 2009). Introduction An ecosystem is a group of organisms living together, interacting with each other and with their surrounding (eoearth.org). It consists of two basic components namely, abiotic and biotic components. The relationship between biotic and abiotic components of an ecosystem is known as holocoenosis (Fisher al et, 2009.They are different types of ecosystem; tropical rainforest, grassland, coral reef, estuary, desert among others. Here, the forces will is on tropical rainforest. Ecosystem has four basic functions; regulatory functions, habitat functions, production functions and information functions. Tropical rainforest A tropical rainforest is an ecosystem type that occurs approximately within the latitudes 28 degrees north/south of the equator. Tropical rainforests ecosystem experiences a significant amount of rainfall and high average temperatures. These rainforests can be found in Australia, Asia Africa, Central America, South America, Mexico and on many of the Caribbean, Pacific, and Indian Ocean islands. The classification within the World Wildlife Fund’s biome describes tropical rainforests as a type of tropical wet forest or tropical moist broadleaf forest. They also referred to it as lowland equatorial evergreen rainforest. Generally, tropical rainforest biome consists; lowland equatorial evergreen rain forest, montane rain forest, flooded forest and moist deciduous and semi evergreen seasonal forest. An example of montane rainforest is the Sierra Nevada of California (WWF). Every ecosystem consists of biotic and abiotic factors; therefore, montane rainforest has both biotic and abiotic ecosystem. Generally, abiotic components include the non-living, physical-chemical factors such as water, air, and soil among other basic elements and compounds of the environment. These abiotic factors are broadly classified into three categories climatic factors, edaphic factors and inorganic substances. Climatic factors in Sierra Nevada are influenced by the Mediterranean climate of California. During the fall, spring and winter, haste in the area averages from 510 to 2,000 mm where it takes place mostly as snow over 1,800 m. Furthermore, summers are dry with low humidity; however, afternoon thunderstorms are usual, specifically during the North American Monsoon. Also, summer high temperatures average 6–32 °C. Moreover, the growing season takes 20 to 230 days, depending strongly on elevation (WWF). An alpine climate experienced in the highest elevations of the Sierra. Consequently, the steepness of the Sierra Escarpment and the height of the range, specifically at the southern end of the range bring forth a wind development referred as the "Sierra Rotor". In addition, this is a horizontal rotation of the atmosphere ,precisely east of the crest of the Sierras, set in movement as a result of strong westerly winds (Fisher et al, 2009). Edaphic factors in Sierra Nevada include; granite which is mostly found east of the crest and north of 37.2°N. Apparently, most soils in the tropical rain forests are characterized by significant poor nutrients and leaching and; however there are fertile soils contained ...Download file to see next pagesRead More

Aquatic and Terrestrial ecosystems

...? Aquatic and Terrestrial ecosystems Aquatic and Terrestrial ecosystems River systems essentially channel the world’s precipitation into surface water systems like lakes and seas. These river systems provide habitats for a vast range of biota, which often culminate in floodplain wetlands that are also regions of astonishing diversity. River systems are critical to most marine, and coastal environments, organisms and processes. Their fresh waters allow humans to infiltrate and dwell in the world’s most inhabitable regions such as deserts. Rivers are the pathways that exemplify ecological landscapes. The climate, as well as the characteristics of land surfaces, determines the hydrology, size, ecology and...

Ecosystems

...Ecosystems part 2 Natural ecosystems supply many resources to human society. These products and processes are known as ecosystem services. There are five categories of service, provisioning, regulating, supporting, cultural and preserving services (Daily, 2000). One such ecosystem is the Greater Yellowstone Ecosystem which provides services from all five categories. One of these categories will be discussed here. 1. What is the ecosystem service The cultural service, in this case the sport fishing of Yellowstone cutthroat trout which are members of the salmon family. 2.

Healthcare ecosystems influences

.... At the same time, the desire to prove the reduced cost the effective functioning is producing new jobs for health care professionals. As such, it enhances effective monitoring, measuring, managing, and coordinating the treatment of patient. Often computer and telecommunications skills are required for these jobs (Bergsma, 2004). This has led to the need for growth and development in the Information Technology departments in Hopkins’ health care units, because of the need for additional management information systems (MIS) and training required in communication and IT. Hence the personnel’s’ clinical ability along with their technical know-how allows them to work either ways. (Meade & Emch, 2010). On...

According to Dinesen (2012), environmental management aims to restore balance and minimize disturbances in an ecosystem. Through conservation measures such as creation of national parks, unique ecosystems are preserved so that future generations may experience nature as it ought to be. He goes on to say that, through pollution control, humans have reduced the amount of pollution they create. This allows ecosystems to recover from past impacts such as acid rain. Through environmental awareness efforts, human society is now more careful with how they interact with the...

I worked as an assistant lab technician which led me discovering the adaptation of the algae plant. The animal laboratory was very busy and with many technicians. They had many sea animal specimens which we dissected so as to understand their body features. We dissected different types of fish, and we were able to identify and compare various organs. To test on our understanding capabilities, we were given simple test to dissect crabs and remove certain organs. We were required to describe the...

Threats to Forest Ecosystems

...to 10% of world’s species. Colombia is blessed with variety of ecosystem that includes rich tropical rain forests, coastal cloud forests and open savannas. The country has 51, 220 species of plants of which 30% are endemic. Only 10% of the country’s area comes under protected areas. Forests in Colombia are under threat of extinction due to human development. As estimated by the UN in 2003 approximately 200,000 hectares of natural forests are lost annually. This figure does not include the 100,000 hectares lost illegally by poor people. Approximately 80% of the country is covered with primary forests and a large portion of it has already been lost. The major reasons of deforestation are agricultural activities, mining,...
