Diagram of the six possible types of symbiotic relationship, from mutual benefit to mutual harm. The definition of symbiosis was a matter of debate for 130 years. [7] In 1877, Albert Bernhard Frank used the term symbiosis to describe the mutualistic relationship in lichens.
Mutualism is an interaction between two or more species, where species derive a mutual benefit, for example an increased carrying capacity. Similar interactions within a species are known as co-operation. Mutualism may be classified in terms of the closeness of association, the closest being symbiosis, which is often confused with mutualism.
For example, mutualistic interactions are vital for terrestrial ecosystem function as: about 80% of land plants species rely on mycorrhizal relationships with fungi to provide them with inorganic compounds and trace elements. [7] estimates of tropical rainforest plants with seed dispersal mutualisms with animals range at least from 70% to 93.5% ...
Ectosymbiosis is defined as a symbiotic relationship in which one organism lives on the outside surface of a different organism. [3] For instance, barnacles on whales is an example of an ectosymbiotic relationship where the whale provides the barnacle with a home, a ride, and access to food.
In each episode, hosts Filip Hammar and Fredrik Wikingsson selected one random elderly person (in Bolivia, Nepal, Senegal, Namibia, Mongolia, Madagascar, and Vietnam) and traced their relationships to different celebrities, including Gordon Ramsay and Buzz Aldrin, with the goal of doing so in six or fewer degrees of separation, within a time ...
In linguistics, lexical similarity is a measure of the degree to which the word sets of two given languages are similar. A lexical similarity of 1 (or 100%) would mean a total overlap between vocabularies, whereas 0 means there are no common words. There are different ways to define the lexical similarity and the results vary accordingly.

In this relationship, the algae provides the coral with a Carbon source to develop its CaCO 3 skeleton and the coral secretes a protecting nutrient-rich mucus which benefits the algae. Perhaps one of the most famous discoveries made by Muscatine in the field of trophic mutualism came about 10 years later in another aquatic based system-the ...
