Tinea cruris, most commonly known as jock itch, is a fungal infection of the skin. It belongs to a group of fungal skin infections called tinea. Like other tinea infections, jock itch is caused by mold-like fungi, which are known as dermatophytes.
Ecologists (scientists who study the relationships of organisms with their living and nonliving environment) generally recognize two kinds of succession, primary succession and secondary succession. Primary succession takes place on an area that is originally completely empty of life. As an example, an area that has been covered by a flow of lava has, for a time, no life at all on it. Over a period of time, however, various kinds of organisms begin to grow in the area.
This non-native species causes extensive ecological damage to native habitats. Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.Secondary succession is usually much quicker than primary succession for the following reasons: There is already an existing seed bank of suitable plants in the soil.his non-native species causes extensive ecological damage to native habitats. Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.
