Stand dynamics stages during succession. 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 ...
One example of the inhibition model, and the priority effect, occurs in South Australia. In areas where bryozoans are established first, tunicates and sponges cannot grow. [13] The inhibition model has also been observed at work in forest ecosystems; in these systems the early arrivers hold a monopoly on the land, keeping other species out.
Ecological succession is the process of change in the species that make up an ecological community over time. The process of succession occurs either after the initial colonization of a newly created habitat, or after a disturbance substantially alters a pre-existing habitat. [1]
Gap models have been used to study forest succession and to investigate the mechanisms underlying the long-term dynamics of forest ecosystems (stand level modelling). [3] [4] [5] Forest Gap models share the following principles: [3] Forests are represented as a collection of small patches. The forest successional stage and age vary across patches.
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...
An image of ecological succession, starting with pioneer species and ending with an old-growth forest that is dominated by climax species, which is denoted by VIII. Climax species, also called late seral , late-successional , K-selected or equilibrium species, are plant species that can germinate and grow with limited resources; e.g., they need ...
Ecological secondary succession is much more common and pertains to the process of vegetation replacement after a natural disturbance. Secondary succession results in second-growth or secondary forest, which currently covers more of the tropics than old-growth forest .
