The term mutualism was introduced by Pierre-Joseph van Beneden in his 1876 book Animal Parasites and Messmates to mean "mutual aid among species". [4] [5] Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis.
An example of ectosymbiotic bacteria is cutibacterium acnes. These bacteria are involved in a symbiotic relationship with humans on whose skin they live. Cutibacterium acnes can cause acne when the skin becomes too oily, but they also reduce the skin's susceptibility to skin diseases caused by oxidative stress. [5]
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.
Commensalism is when the pathogen benefits while the host gains nothing from the interaction. An example of this is Bacteroides thetaiotaomicron, which resides in the human intestinal tract but provides no known benefits. [6] Mutualism occurs when both the pathogen and the host benefit from the interaction, as seen in the human stomach.
The influence of human behaviour on domesticated animals has led to many species having learned to co-exist - sometimes leading to the formation of an interspecies friendship. For example, interspecies friendships are often observed in humans with their domesticated pets and in pets that live in the same household such as cats and dogs. [1] [17]
Mutualism is an interaction between species that is beneficial to both. A familiar example of a mutualism is the relationship between flowering plants and their pollinators. [2] [3] The plant benefits from the spread of pollen between flowers, while the pollinator receives some form of nourishment, either from nectar or the pollen itself.
Perhaps global mutualism coextinctions are genuinely uncommon, and the model predictions are inaccurate. The models may overestimate the specificity of the mutualisms, because species may only associate with alternative species when their 'normal' mutualist is rare or absent. For example, oligolectic bees visit a small number of flowers for ...
