Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms ( biodiversity ) and abiotic properties such as nonliving things like water or soil ...
However, as the term forest connotes an area inhabited by more than one organism, forest ecology most often concentrates on the level of the population, community or ecosystem. Logically, trees are an important component of forest research, but the wide variety of other life forms and abiotic components in most forests means that other elements ...
Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions. [1] Structurally, these forests are rather simple, consisting of 2 layers generally: an overstory and understory. However, some forests may support a layer of shrubs.
An abstract diagram showing forest succession over time. Increase in biomass, biodiversity and soil thickness are also shown, as well as the fluctuation of different plant communities over the process of succession. Forest succession is the process by which species recover and regenerate after a disturbance. The type of disturbance, the climate ...
As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term biogeochemical processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and seafloor ...
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus , live oak , acacias , magnolia , and banksia in more temperate zones, and rainforest trees in tropical zones.
Forest canopies have unique structural and ecological complexities and are important for the forest ecosystem. They are involved in critical functions such as rainfall interception, light absorption, nutrient and energy cycling, gas exchange, and providing habitat for diverse wildlife. [ 11 ]
This significant drop in the ecosystem acreage marks a 97 percent decrease. In overlook of the ecosystem, today, it is described as being patchy and uneven in the distribution across the landscape. [19] [20] Of the now 3 percent ecosystem acreage, there are a documented 8,856 acres (3,584 ha) of old growth longleaf pine stands left. [20] [21]
