Biological interaction

Interspecific interactions are relationships between individuals or populations of different species. You may obstruct or promote for a participant, or both. Interspecific interactions are an important object of study of ecology. The opposition to them are relations between individuals of the same species, ie intra -specific relationships.

Interspecific relationships lead to the adaptation of the survival, reproduction and foraging strategies of the species involved. Adapt to two types each in a special way to each other, it is called co-evolution.

Different forms of interspecific interactions

• If both participants benefit, then one speaks of a symbiosis ( in the broad sense ). Rather loose partnerships are referred to as Allianz, short-term partnerships for mutual benefit as mutualism. Ways of life so closely that the partnership of very high importance or is regularly even vital, it is called symbiosis in the strict sense.

• If one of the parties affected by the interaction, this is called antibiosis. The antibiosis in which one partner obtains benefits from the relationship, including parasitism and Episitismus (predator -prey relationship). In the case of interspecific competition either both damaged ( symmetric competition) or a kind of be damaged, while the other remains unaffected (asymmetric competition).

• In Probiosen (rarely also called Karposen ) a participant has a benefit, the other any harm or benefit. Forms of Probiose are. e.g. Parökie, Synökie, Epökie and Phoresy.
