Succession ecological

Ecological succession is the orderly process of community change and is the sequence of communities which replace one another in a given area (3). Generally, the driving force behind succession has been attributed to changes of physical factors in the habitat, availability of essential minerals, differences in seed production and dispersal, competition, or a combination of these. In addition, Rice and co-workers (as cited in 1 ) have indicated that... 

There are numerous reports of allelopathy in the literature, but often the identity of the allelochemical(s) is unknown. There are, however, many cases where specific compounds or groups of compounds have been implicated as allelopathic agents. Table 1 summarizes some examples of sources and identities of allelochemicals that directly inhibit plant growth. These secondary compounds have been implicated as a driving force in ecological succession ( 1 ).

Because the enzyme targeted by glyphosate is not present in humans or other animals, the product is advertised as entirely safe by the industry. The EPA rates glyphosate as toxicity class II—practically nontoxic even by direct ingestion. Industry advocates celebrate glyphosate as an international ecological success. ...

Of course, there are limitations to the ecological success of opportunistic species. In stable environments, where disturbance is infrequent, there are few circumstances that are favorable to opportunistic species, and they will be rare in the biota. Such conditions are common, for example, in old-growth forests and other climax ecosystems. However, many human activities result in extensive disturbances of natural ecosystems. As a result, opportunistic species are faring much better today than they did prior to the global environmental changes that are being caused by humans. 

The standing stock of a resource can alter for reasons unconnected with its use (e.g. related to ecological succession). Production of medicinal plants ex situ as a substitute for harvesting from the wild, as a source of income for the herbalist and communities, and different sections of society can place different values on...

Ecological Succession and Stability. As this comparison between algae pond and coral reef epitomizes for two ecosystems of comparable primary plant productivity, the more diversified system is more resistant to external perturbations. Although the cause and effect relationship...
