One of the regions that have been greatly influenced by deforestation is the Amazon Basin. Tree felling in the Amazon is much greater compared to any other region of the world. The Amazon tropical forest, which approximately account for 2,488,642 square miles, lost fifteen percent of its forest cover in1970 alone (Naik, 2010). For example, Brazil, which is a residence to about one-thirds of the tropical forests of the world, has been incurring an average loss of 21,536 square miles of forest cover yearly, over the last few years (Olsen, 2009). Deforestation and the consequences on biodiversity interactions In areas of intense deforestation, there exists alterations in microclimate and change in plant reproduction, biological structure and animal distribution, among many other aspects of the forest. Climate change due to overexploitation of forests and plant communities results into loss of biodiversity both the flora and fauna. Climate change causes rise in temperature and low moisture availability in the affected regions and even spreads out (Eade, 2011). Due to the change in climate, there emerges simultaneous increase in the occurrence of fires which actively destroy the plant communities. Forests assist to uphold the temperature at a low level and avert it from rising. In the deficiency of forest, the earth surface radiates all the heat that the atmosphere does not absorb but instead hit the earth’s surface. Such heat combined with an increase in the concentration of carbon dioxide leads to an increase in the atmospheric temperature (Haldar, 2011). Average species lost compared to deforestation rates (Eade, 2011). Climate change emanates into harsh conditions that can easily results into extinction of some animal and epiphytes community. A good example is the scenario whereby, Mycchorizal fungal interactions between plants and the fungi are affected. These two have a symbiotic relationship. In sustaining base level of supply of food, rain forests depend on the microbe’s action of decaying and rotting. In the event that forest cover is reduced, the fungi have less survival rates since they depend on trees for both habitat and food (Haldar, 2011). The impact of deforestation leads to changes in aquatic systems through excessive evaporations. The salinity level increases and the temperature becomes unbearable hence, habitat of the aquatic flora and fauna compromised. Excessive carbon IV oxide due to deforestation also chokes the flora and fauna that are found in the aquatic ecosystem hence reduction of the species that are not best suited for this environment for example, algae ...Download file to see next pagesRead More

Silt recycling companies

...? Topic: Silt recycling Companies Lecturer presentation Introduction Silt is an important component produced in many natural and artificial processes. According to Yabuki (2006: 51), agricultural and industrial processes produce vast volumes of silt annually. A study conducted in United Kingdom, established that five soil-washing plants produced about 1000 tonnes of silt per day (Calabrese, et al. 2005). The composition and the quality of silt differ, but high concentration of diverse minerals and large volumes of silt have jolted many companies into recycling the sediments. Volkmar, et al, (2005:43) noted that silt is formed from various weathering processes that result to the breakdown of weakened sand quartz crystals structures... , the...

Biotic Components

..., it can be highly dangerous for other living in the pond as many animals might feed on that specie for nutrients and the whole system might crash. Due to the climate change, excessive heat in the environment, drought can appear killing all the species living there. The growth of thick trees around the pond can block the passage of sunlight to the pond, resulting in death of plants and thus the animals. Besides this, natural succession can occur which can totally change the biotic community. It actually occurs due to the changes in the plants, animals or other a-biotic factors, and so a new eco cycle can begin How humans may have affected biogeochemical...

The water hyacinth plant has a negative impact on the community living in the shores of Lake Victoria. The community depend on fish as their source of livelihood and water hyacinth is responsible in making the waters inhabitable for the fish. Forests are also habitats for wild animals that attack the communities dwelling in their precincts. The indigenous plants growing in Kenyan forests influence social activities like camping and hiking. Some communities name plants...

Plant Psychology

...Plants do some amazing things; photosynthesis is outstanding work, and so is splitting water molecules. Plants can even communicate amongst each other by releasing chemicals into the air. These chemicals were 'unknown' to humans until we developed instruments sensitive enough to detect them. So, plants do not need to be endowed with superhuman attributes to be displaying psychology. Backster in 1968 claimed that all living cells are capable of "primary perception," a form of direct biological communication. He monitored the electrical resistance on the surface of one leaf on each of three philodendrons to see if they would respond at the moment of...

Biodiversity of Coastal and Exposed Shores

...that biotic factors (interactions with other living organisms) become more important than abiotic factors (interactions with the non-living part of the environment) in determining the distributions of organisms. Most algae are shade plants and are adapted to absorb low amounts of light energy. This applies especially to red algae and they may begin to appear on the lower shore. Most of the time the light they receive there is attenuated by its passage through the covering sea water. Lots of wave action does not usually equate with success for seaweeds though and so there will not be as many species or as greater quantity as on a sheltered shore. You may find coral weed...

Cultural Interactions

...continues through all democracies, even modern America. The make-up of the Greek state as a collection of smaller units resembles the modern Federal structure of the U.S., but the scale is very much greater in America. The amount of commitment required from individual male citizens in Ancient Greece, and the complete absence of women in the political world are major differences from present day politics, and it is good that we have moved on from that. Of the two ancient systems I prefer the Athenian one, because it is more inclusive, for men at least. This lecture has made me wonder, however, whether America is drifting more towards the warlike Sparta model, and that is something that I will reflect upon a bit more in...

... Community Having the morning coffee is a community. Every morning, I have the habit of having my coffee in the nearby café with a group of my friends. This socializing action among our group makes a community, as we usually engage in talks, exchanging stories, and having fun. Actually, since the existence of creation, man used to live and exist in small groups and communities that share common habits, values, and interests. As life advances through ages, the concept of socialization deepens as millions of cultures and sub-cultures come to existence around the world. So, what makes a group like ours a community is the existence of values, norms, customs, and traditions that are shared and respected by one group of people... . As such, the...

Social Interactions

...Social Interactions One of the important bases of a communal interaction is that the interaction is on a personal level between individuals. Individuals tend to know each other exceedingly well and because of this, their interaction tends to be extremely informal. An example of this is between neighbors who have lived next to each other for years. In an associational interaction, on the other hand, the interaction between the people involved tends to be terribly impersonal, and a casual interaction often remains formal throughout its duration. An example of an associational interaction is that between an individual and a cashier in a food store (Tschan 145). Another basis of interaction that can be compared is based on how... this...

...The US Government should have a certification program for foods containing genetically modified ingredients. A genetically modified organism is a plant, animal or microorganism which is not made naturally such as crossing species (“GMOs: The Greatest Threat to Mankind”). Citizens are eating genetically modified food without any idea at all. These ingredients or organisms are produced and consumed in the United States without any labels. Until today, there is still a great debate whether or not the genetically modified ingredients or organisms pose threats to humankind. Thus the question whether or not the United States government should have a certification program for foods containing genetically modified ingredients...
