An ideal examples of r-selected groups are algae. Based on the contradictory characteristics of both of these examples, areas of occasional disturbance allow both r and K species to benefit by residing in the same area. The ecological effect on species relationships is therefore supported by the intermediate disturbance hypothesis.
Logging, dredging, conversion of land to ranching or agriculture, mowing, and mining are examples of anthropogenic disturbance.Human activities have introduced disturbances into ecosystems worldwide on a large scale, resulting in widespread range expansion and rapid evolution of disturbance-adapted species. [7]
The Aral Sea is an example of a collapsed ecosystem. [1] (image source: NASA) An ecosystem, short for ecological system, is defined as a collection of interacting organisms within a biophysical environment. [2]: 458 Ecosystems are never static, and are continually subject to both stabilizing and destabilizing processes. [3]
Ecological threshold is the point at which a relatively small change or disturbance in external conditions causes a rapid change in an ecosystem.When an ecological threshold has been passed, the ecosystem may no longer be able to return to its state by means of its inherent resilience.
This results shows another example of how the ecological extinction of a keystone predator can reduce species diversity in an ecosystem. The threshold of ecological extinction has passed due to over fishing so that local extinctions of the California spiny lobster are common.
Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda. Natural vegetation along this coastal shoreline in North Carolina, US, is being used to reduce the effects of shoreline erosion while providing other benefits to the natural ecosystem and the human community.
It can be measured by the ecological footprint, a resource accounting approach which compares human demand on ecosystems with the amount of planet matter ecosystems can renew. Estimates by the Global Footprint Network indicate that humanity's current demand is 70% [27] higher than the regeneration rate of all of the planet's ecosystems combined ...
Examples of animal overpopulation caused by introduction of a foreign species abound. In the Argentine Patagonia , for example, European species such as the trout and the deer were introduced into the local streams and forests, respectively, and quickly became a plague, competing with and sometimes driving away the local species of fish and ...
