Commensalism - Definition, types and examples

In nature there are symbiotic relationships between the different organisms to achieve an end.There are relationships where one of the parties obtains very negative results, as in cases of predation or parasitism.In other relationships, sometimes, not even everyone involved knows that they are part of a relationship.This is the case of commensalism.

In this article of Animals and Pets Online we will discover the definition of commensalism, we will see what types exist and some examples of commensalism.Keep reading!

What is commensalism?

Biological commensalism is defined as the relationship between two organisms of different species, where one of them benefits and the other does not get anything , neither positive nor negative.of the relationship for one of them is neutral.

Commensalism is a type of symbiosis that, unlike others, such as parasitism or predation, does not result in a negative ending for any of the parties involved On the other hand, the difference between mutualism and commensalism is that, in the first case, both individuals obtain benefits.

Commensalism in microbiology has also been widely studied., in a column of water, microorganisms that live closer to the surface usually benefit from sunlight, essential for their development.Their waste substances travel through the water column until they reach the bottom, where sunlight is scarce and oxygen.Here, anaerobic microorganism (who do not need oxygen to live) take as substances and energy sources the substances that arrive from the surface.

The microorganisms of the bottom benefit from the microorganisms of surfaces, while these do not obtain anything.highlight here the term amensalism .Contrary to commensalism, in these relationships one of the parties is harmed while the other remains immutable.It is the case of certain fungi such as Penicillium , which secrete antibiotics preventing the proliferation of bacteria.

Types of commensalism

When studying the relationships established between living beings, the great variety that exists forces us to subclassify commensalism into three different types, since there is no single way in which the animals of mutualism benefit:

  • Foresis : the term foresis refers to the relationship that is established between two species when one of them transports the other.In most cases, the transporter He is not even aware that he is transporting another living being.
  • Tenancy : Tenancy occurs when one species occupies the body of another to live, without causing any discomfort.
  • Metabiosis : This type of commensalism is very common in the animal kingdom.It occurs when a species feeds on the waste of another, such as its feces or the body itself in decomposition or the case of anaerobic microorganisms that we discussed before.

Examples of commensalism

There are many commensalist relationships in the animal kingdom.Many of these relationships occur between members of this kingdom with organisms from the plant kingdom.Some of these examples are:

1.Comensalism between opiliones and ants

In certain areas of Argentina, where this relationship has been discovered, the climate is very dry, which makes the presence of opiliones impossible, social animals belonging to the order of the arachnids.The ant hills offer a more humid microclimate that favors the opiliones.These live inside the anthill without causing the ants benefits or harms.

2.Comensalismo between the giant lizard of the island of El Hierro ( Gallotia simonyi ) and the yellow-headed gull ( Larus michahellis )

Non-volatile chickens of this species of gull regurgitates part of the food when they feel very full or are bothered by other adult seagulls.Then, the giant lizard will benefits feeding on the regurgitated insects by the seagull chicken.

3.Comensalism between vulgar finches ( Fringilla coelebs ) and black starlings ( Sturnus unicolor )

Starlings, in Leon, to the northwest of Spain, they feed on blackberries in summer.When they eat they drop seeds on the ground or on the leaves of the mulberry.Finches, granivorous animals, search between the leaves and the ground, the discarded seeds for starlings , taking them even directly from the feces of starlings.

4.Canalism among flies and ham mites

This is a very curious example of foresis.Ham dryers sometimes have problems with losacaros, that bite the ham and invalidate it for sale.The hams are hung on the ceiling so the invasion poracaros would seem complicated.These animals are mounted on the flies that they visit the hams.When they arrive at a ham, the mites get off the fly.The flies do not get anything, they do not even realize that they are transporting mites.

5.Comensalism between birds Yarns

Birds that nest in trees get this protection n and a place to build your nest.Trees don't get anything, neither positive nor negative.
