Structure‚ Species Interactions‚ Succession‚ and Sustainability I. Appearance and Species Diversity A. The structure or spatial distribution of a community or ecosystem can be described by: a. Physical Appearance : relative sizes‚ stratification‚ and distribution of its population and species b. Species Diversity or Richness : the number of different species c. Species Abundance : the number of individuals of each species d. Niche Structure : the number of ecological niches‚ how they resemble

Hemisphere‚ the British Isles bears a variety of trees and successions of plants‚ including deciduous trees. The main ecosystem of the country is made up from forest and lake biomes alongside heathlands and moorlands such as heather moorland. The changes to the vegetation over time can be affected by both physical and human factors which in some cases occur together or in causation of one another. Physical changes include; changes in climate‚ succession‚ disease and natural disasters. Human factors in change

Abiotic: non-living factors or components‚ e.g. soil‚ water‚ wind‚ etc… 2.1.2 Trophic level: is the position that an organism or a group of organisms in a community occupies in a food chain. 2.1.3 A food chain shows the flow of energy from one organism to the next. A food web is a complex network of interrelated food chains. Producers (autotrophs): manufacture their

Secondary succession‚ as described in Campbell (1996)‚ is the type of succession that occurs when the soil is intact and accommodates a considerable amount of nutrients that can support life. This succession is primarily dependent on the pioneer species (e.g mosses‚ weeds and etc.) which tends the soil from its lifeless state. Since pioneer species

Explain how ecosystems recover naturally based on resilience mechanisms and the theory of secondary succession. The following grading rubric will be used for this assignment.

given amount of time. This causes restoration of plant species in a disturbed area to replace one another. There are two types of succession‚ primary and secondary. Primary succession is described as a habitat that lack plants and organic soil and secondary is described as a habitats that have been were disturbed‚ do not have any plant life but contain organic soil. Succession of new species connects to the plant communities’ competition over light‚ nutrients‚ and water. This competition can lead to a

with one another and their physical habitats they change the composition of the community which is called succession. ~Primary succession occurs in a preciously unoccupied area beginning with pioneer species that allow soil to develop paving the way for additional organisms to thrive. ~Secondary succession is more rapid than primary succession because soil does not have to build anew. ~Succession may lead toward a stable climax community but true long-term stability is rare.

Winthrop University’s Successional Plot’s Soil P.H. Meredith Hamilton Biology- Westover September 30‚ 2011 Abstract The question of this study pertained to the amount of vegetation that was occurring on each of the succession plot’s ground floor. There are three successional plots in Winthrop University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to

“The vegetation of the UK has been so massively affected by human activity that there is now no climax vegetation left. The whole country is now effectively a plagio-climax. Discuss this statement. (40 marks) A plagio-climax is the plant community that exists when human interference prevents the climatic climax from being reached. The plagio-climax of Britain is heather moorland as it is maintained by human intervention. The uplands of Britain use to be covered by a climax vegetation of deciduous

General What is the Ecological Footprint? The Ecological Footprint is a resource accounting tool used widely as a management and communication tool by governments‚ businesses‚ educational institutions and NGOs to answer a specific resource question: How much of the biological capacity of the planet is required by a given human activity or population? What does the Ecological Footprint measure? The Ecological Footprint measures the amount of biologically productive land and sea area an individual
