The monkey gets most of its nutrients from a gnarly tree called the whistling thorn acacia, in a type of interaction called commensalism, wherein one organism benefits from another without harming it.

Phoresy is another type of commensalism, the commensal uses the host solely for transport. Many mite species rely on another organism, such as birds or mammals, for dispersal. Metabiosis is the final form of commensalism. The commensal relies on the host to prepare an environment suitable for life.
|
|
This differs from the conventional belief that commensalism is the ideal equilibrium for both the host and parasite.

Remora fish form ectosymbiotic commensalism interactions with a lemon shark in order to scavenge food and travel long distances.

These shared resources support commensalism between the two species. For D. montana, this relationship is typically observed in North America, specifically with the beaver species Castor canadensis.

Commensalism is a type of relationship among organisms in which one organism benefits while the other organism is neither benefited nor harmed. The organism that benefited is called the commensal while the other organism that is neither benefited nor harmed is called the host. For example, an epiphytic orchid attached to the tree for support benefits the orchid but neither harms nor benefits the tree. This type of commensalism is called inquilinism, the orchid permanently lives on the tree.

Associated with the term "symbiosis" are terms: mutualism, commensalism, parasitism, and amensalism. This may define or limit the type of "living together" of two organisms, be they plant, animal, protist or bacteria they practice.
|
|
The word "commensalism" is derived from the word "commensal", meaning "eating at the same table" in human social interaction, which in turn comes through French from the Medieval Latin commensalis, meaning "sharing a table", from the prefix com-, meaning "together", and mensa, meaning "table" or "meal". Commensality, at the Oxford and the Cambridge Universities, refers to professors eating at the same table as students (as they live in the same "college"). Pierre-Joseph van Beneden introduced the term "commensalism" in 1876.van Beneden, Pierre-Joseph (1876).

Symbiosis refers to two or more biological species that interact closely, often over a long period of time. Symbiosis includes three types of interactions—mutualism, commensalism, and parasitism—of which only mutualism can sometimes qualify as cooperation. Mutualism involves a close, mutually beneficial interaction between two different biological species, whereas "cooperation" is a more general term that can involve looser interactions and can be interspecific (between species) or intraspecific (within a species). In commensalism, one of the two participating species benefits, while the other is neither harmed nor benefitted.

Inquilinism: Tillandsia bourgaei growing on an oak tree in Mexico Inquilinism is the use of a second organism for permanent housing. Examples are epiphytic plants (such as many orchids) that grow on trees,C. Michael Hogan. 2011. Commensalism. Topic Ed. M.Mcginley.

The rove beetle Velleius dilatatus lives together with the European hornet Vespa crabro. Velleius dilatatus is up to 26 mm long. It feeds on detritus produced by the hornets (an example of commensalism). The beetles cannot survive without the hornets themselves, even if there is enough detritus present.
|
|
Commensalism benefits one organism and the other organism is neither benefited nor harmed. It occurs when one organism takes benefits by interacting with another organism by which the host organism is not affected. A good example is a remora living with a manatee. Remoras feed on the manatee's faeces.
|
|
Smaller remoras also fasten onto fish such as tuna and swordfish, and some small remoras travel in the mouths or gills of large manta rays, ocean sunfish, swordfish and sailfish. The relationship between a remora and its host is most often taken to be one of commensalism, specifically phoresy.

|
Demodex folliculorum is a microscopic mite that can only survive on the skin of humans. Most people have D.folliculorum on their skin. Usually, the mites do not cause any harm, and are therefore considered an example of commensalism rather than parasitism. If D.folliculorum does cause disease, this is known as demodicosis.

Prey items such as flies, ants, spiders, and even moths, are then digested by an invertebrate community, made up mostly by the mosquito Wyeomyia smithii and the midge Metriocnemus knabi. The relationship between W. smithii and S. purpurea is an example of commensalism.C. Michael Hogan. 2011. Commensalism. Topic Ed. M.Mcginley.

Overview of bacterial infections and main species involved. Despite their apparent simplicity, bacteria can form complex associations with other organisms. These symbiotic associations can be divided into parasitism, mutualism and commensalism. Due to their small size, commensal bacteria are ubiquitous and grow on animals and plants exactly as they will grow on any other surface.
|
|
Currently, ecological networks that integrate non-trophic interactions are being built. The type of interactions they can contain can be classified into six categories: mutualism, commensalism, neutralism, amensalism, antagonism, and competition. Observing and estimating the fitness costs and benefits of species interactions can be very problematic. The way interactions are interpreted can profoundly affect the ensuing conclusions.

552 p. Commensalism is similar to facilitation, in that one plant is mostly exploiting another. A familiar example is the ephiphytes which grow on branches of tropical trees, or even mosses which grow on trees in deciduous forests. It is important to keep track of the benefits received by each species to determine the appropriate term.
|
|
Lichen associations may be examples of mutualism, commensalism or even parasitism, depending on the species. There is evidence to suggest that the lichen symbiosis is parasitic or commensalistic, rather than mutualistic. The photosynthetic partner can exist in nature independently of the fungal partner, but not vice versa. Photobiont cells are routinely destroyed in the course of nutrient exchange.

Having overlapping territories with P. trewavasae may benefit T. moorii individuals because both defend their territory from much larger P. orthognathus individuals. They also are able to drive them away, whereas an individual blunthead cichlid may not be able to defend territory successfully. This is an example of commensalism rather than mutualism because individuals would defend their territories regardless.

"Yucca moths" have a remarkable biology. They are famous for an old and intimate relationship with Yucca plants and are their obligate pollinators as well as herbivores. Interactions of these organisms range from obligate mutualism to commensalism to outright antagonism. Their bore holes are a common sight on trunks of such plants as the soaptree yucca.

Microbes, especially bacteria, often engage in symbiotic relationships (either positive or negative) with other microorganisms or larger organisms. Although physically small, symbiotic relationships amongst microbes are significant in eukaryotic processes and their evolution. The types of symbiotic relationship that microbes participate in include mutualism, commensalism, parasitism, and amensalism, and these relationships affect the ecosystem in many ways.

The dingo is regarded as a feral dog because it descended from domesticated ancestors. The dingo's relationship with indigenous Australians is one of commensalism, in which two organisms live in close association, but do not depend on each other for survival. They both hunt and sleep together. The dingo is, therefore, comfortable enough around humans to associate with them, but is still capable of living independently.
|
|
Among various types of symbiotic relationships, mutualism is where partners mutually benefit. Commensalism is a relationship where one partner receives a benefit while the other is not affected. There is parasitism, where one partner benefits while it is at the expense of the host. And amensalism is a less common type of relationship where one organisms receives no benefit but the host still has negative ramifications.
|
|
Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an association is much larger than the other, it is generally known as the host. In parasitism, the parasite benefits at the host's expense. In commensalism, the two live together without harming each other, while in mutualism, both parties benefit.

Erycina pusilla can be found in the neotropical region, including South and Central America, the southern Mexican lowlands, the Caribbean islands and southern Florida. Its habitat consists of humid forests at elevations of with temperatures varying from warm to hot. Like many orchids, E. pusilla grows harmlessly upon other plants. It gets moisture and nutrients from the surroundings without affecting the host plant (commensalism).

Symboisis is the close bond relationship between the two individuals of two different species. Commensalism is when organisms make similar demands on the environment often resulting in competition. Hawley believed humanity was dominant in the ecosystem due to advances in technology and humanity's control over the habitat. He contended that through culture humanity is able to modify its subsistence to match its needs and desires.

The damage-response framework was the first theory of microbial pathogenesis to incorporate the contributions of both the host and the pathogen and refocused attention into the outcome of the interaction. From the view of the damage-response framework there are no pathogens, commensals, symbionts, etc., but only microbes and their hosts, which interact to produce the states of pathogenesis, commensalism, symbiosis, indifference, etc.

The fallen trees and stripped bark produced by beaver activity provides popular sites for oviposition of the virilis group of Drosophila, including the fruit fly Drosophila montana. Capture of these species of Drosophila for research is significantly more successful near beaver residences. The preference of beavers for birch, willow, and alder corresponds with oviposition site preferences of the Drosophila virilis species group, leading to commensalism between beavers and these species.

Journal of Morphology, 273 (12) 1353-1366 , DOI: 10.1002/jmor.20063 An additional ectosymbiotic example of commensalism is the relationship between small sessile organisms and echinoids in the Southern ocean, where the echinoids provide substrate for the small organisms to grow and the echinoids remain unaffected. Branchiobdellid annelids are mutualistic parasites. They will attach to a signal crayfish and feed on diatoms, bacteria, and protozoans that accumulate on the exoskeleton.
|
|
The opposite of commensalism is amensalism, an interspecific relationship in which a product of one organism has a negative effect on another organism but the original organism is unaffected. An example is the interaction been tadpoles of the common frog and a freshwater snail. The tadpoles consume large amounts of micro-algae. Making algae less abundant for the snail, the algae available for the snail is also of lower quality.

Commensalism is very common in microbial world, literally meaning "eating from the same table". Metabolic products of one microbial population are used by another microbial population without either gain or harm for the first population. There are many "pairs "of microbial species that perform either oxidation or reduction reaction to the same chemical equation. For example, methanogens produce methane by reducing CO2 to CH4, while methanotrophs oxidize methane back to CO2.

The sedentary species in this genus live on the underside of stones or commensally with their shells loosely attached to other and larger gastropods or invertebrates. This commensalism results in some morphological changes : a thin basal plate, a very long snout and a small osphradium. They live in colonies with a few big females are surrounded by many smaller males. The egg mass is kept within the female shell.

Metriocnemus knabi, the pitcher plant midge, is an inquiline invertebrate found only in the phytotelma of the purple pitcher plant, Sarracenia purpurea. In this microcommunity of bacteria, rotifers, protozoa, and other dipteran larva like Wyeomyia smithii, M. knabi specializes by feeding mostly on the carcasses of drowned insects captured by the plant that collect at the bottom of the pitcher.Heard, S. B. (1994). Pitcher-plant midges and mosquitoes: a processing chain commensalism.

Depending on how the pathogen interacts with the host, it can be involved in one of three host–pathogen interactions. 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. Mutualism occurs when both the pathogen and the host benefit from the interaction, as seen in the human stomach.

They may live alongside red foxes (Vulpes vulpes) in isolated sections of large burrows. The two species possibly tolerate each other out of commensalism; foxes provide badgers with food scraps, while badgers maintain the shared burrow's cleanliness.Dale, Thomas Francis, The fox, Longmans, Green, and Co., 1906 However, cases are known of badgers driving vixens from their dens and destroying their litters without eating them. In turn, very large male red foxes are known to have killed badgers in spring.

However, polychaetes vary widely from this generalised pattern, and can display a range of different body forms. The most generalised polychaetes are those that crawl along the bottom, but others have adapted to many different ecological niches, including burrowing, swimming, pelagic life, tube-dwelling or boring, commensalism, and parasitism, requiring various modifications to their body structures. The head, or prostomium, is relatively well developed, compared with other annelids. It projects forward over the mouth, which therefore lies on the animal's underside.

However, many strains of S. aureus are metabiotic commensals, and are present on roughly 20 to 30% of the human population as part of the skin flora. S. aureus also benefits from the variable ambient conditions created by the body's mucous membranes, and as such can be found in the oral and nasal cavities, as well as inside the ear canal. Other Staphylococcus species including S. warneri, S. lugdunensis and S. epidermidis, will also engage in commensalism for similar purposes.

The microbiota describes the sum of all symbiotic microorganisms (mutualism, commensalism or pathogenic) living on or in an organism. The fruit fly Drosophila melanogaster is a model organism and known as one of the most investigated organisms worldwide. The microbiota in flies is less complex than that found in humans. It still has an influence on the fitness of the fly, and it affects different life-history characteristics such as lifespan (life expectancy), resistance against pathogens (immunity) and metabolic processes (digestion).

The first British colonists to arrive in Australia established a settlement at Port Jackson in 1788 and recorded dingoes living there with indigenous Australians. Although the dingo exists in the wild, it associates with humans but has not been selectively bred as have other domesticated animals. The dingo's relationship with indigenous Australians can be described as commensalism, in which two organisms live in close association but without depending on each other for survival. They will both hunt and sleep together.

Commensalism, a concept developed by Pierre-Joseph van Beneden (1809–1894), a Belgian professor at the University of Louvain during the nineteenth century Poreau B., Biologie et complexité : histoire et modèles du commensalisme. PhD Dissertation, University of Lyon, France, 2014. is central to the microbiome, where microbiota colonize a host in a non-harmful coexistence. The relationship with their host is called mutualistic when organisms perform tasks that are known to be useful for the host, parasitic, when disadvantageous to the host.

Head (scolex) of tapeworm Taenia solium, an intestinal parasite, has hooks and suckers to attach to its host. Parasitism is a kind of symbiosis, a close and persistent long-term biological interaction between a parasite and its host. Unlike saprotrophs, parasites feed on living hosts, though some parasitic fungi, for instance, may continue to feed on hosts they have killed. Unlike commensalism and mutualism, the parasitic relationship harms the host, either feeding on it or, as in the case of intestinal parasites, consuming some of its food.

In most environmental situations the presence or absence of an organism is determined by a complex web of interactions only some of which will be related to measurable chemical or biological parameters. Flow rate, turbulence, inter and intra specific competition, feeding behaviour, disease, parasitism, commensalism and symbiosis are just a few of the pressures and opportunities facing any organism or population. Most chemical constituents favour some organisms and are less favourable to others. However, there are some cases where a chemical constituent exerts a toxic effect. i.e.

Commensalism is a form of symbiosis where one species is benefiting from the interactions between species and the other is neither helped nor harmed from the interaction. Ectosymbiotic commensalistic behavior is found frequently in organisms that attach themselves to larger species in order to move long distances or scavenge food easily; this is documented in remoras which attach to sharks to scavenge and travel.Britz, R. & G. D. Johnson. 2012. Ontogeny and homology of the skeletal elements that form the sucking disc of remoras (Teleostei, Echeneoidei, Echeneidae).

Approximately 60% of all plants, for example, have a symbiotic relationship with arbuscular mycorrhizal fungi living in their roots forming an exchange network of carbohydrates for mineral nutrients. Indirect mutualisms occur where the organisms live apart. For example, trees living in the equatorial regions of the planet supply oxygen into the atmosphere that sustains species living in distant polar regions of the planet. This relationship is called commensalism; because, many others receive the benefits of clean air at no cost or harm to trees supplying the oxygen.

A pea crab (yellow in color) has fallen out of the clam that this sea otter is eating, and has landed on the sea otter's neck (in Moss Landing, California) The relationship between the pea crab and its host is one of parasitism, rather than commensalism, since the host may be harmed by the crab's feeding activities. The pea crab relies solely on its host for food, safety, and oxygen. Pea crabs have a variety of hosts, the most important of which are mollusks. The pea crab lives in the mantle cavity of these hosts.

Commensalism, which is a relationship where one organism benefits from living on or with another organism without harm, occurs with two species of muscid flies: Fannia canicularis, which is commonly known as the lesser house fly, and Dendrophaonia querceti. Females of both species lay their eggs directly on the outer portion of the nest envelope. So when the eggs hatch, the larvae fall into the soil below the nest, where waste products and debris also fall. The larvae feed on this waste, thereby preventing waste and debris buildup under the nest.

One of the most daunting tasks involved in studying parasitic relationships from the past is supporting the assertion that the relationship between two organisms is indeed parasitic. Organisms living in "close association" with each other may exhibit one of several different types of trophic relationships, such as parasitism, mutualism, and commensalism. Demonstration of true parasitism between existing species typically involves observing the harmful effects of parasites on a presumed host. Experimental infection of the presumed host, followed by recovery of viable parasites from that host also supports any claim of true parasitism.

European mistletoe is an example of an ectosymbiotic parasite that lives on top of trees and removes nutrients and water. Ectosymbiosis is form of symbiotic behavior in which a parasite lives on the body surface of the host, including internal surfaces such as the lining of the digestive tube and the ducts of glands. The parasitic species is generally an immobile, or sessile, organism existing off of biotic substrate through mutualism, commensalism, or parasitism. Ectosymbiosis is found throughout a diverse array of environments and in many different species.

The leap from a synanthropic population to a domestic one could only have taken place after the animals had progressed from anthropophily to habituation, to commensalism and partnership, at which point the establishment of a reciprocal relationship between animal and human would have laid the foundation for domestication, including captivity and then human-controlled breeding. From this perspective, animal domestication is a coevolutionary process in which a population responds to selective pressure while adapting to a novel niche that includes another species with evolving behaviors. Commensal pathway animals include dogs, cats, fowl, and possibly pigs.
|
|
Since 2012, a multi-stage model of animal domestication has been accepted by two groups. The first group proposed that animal domestication proceeded along a continuum of stages from anthropophily, commensalism, control in the wild, control of captive animals, extensive breeding, intensive breeding, and finally to pets in a slow, gradually intensifying relationship between humans and animals. The second group proposed that there were three major pathways that most animal domesticates followed into domestication: (1) commensals, adapted to a human niche (e.g., dogs, cats, fowl, possibly pigs); (2) prey animals sought for food (e.g.

Commensal mites travelling (phoresy) on a fly (Pseudolynchia canariensis) Commensalism describes a relationship between two living organisms where one benefits and the other is not significantly harmed or helped. It is derived from the English word commensal, used of human social interaction. It derives from a medieval Latin word meaning sharing food, formed from com- (with) and mensa (table). Commensal relationships may involve one organism using another for transportation (phoresy) or for housing (inquilinism), or it may also involve one organism using something another created, after its death (metabiosis).

Parasites are organisms which live in close association with another organism, called the host, in which the parasite benefits from the association, to the detriment of the host. Many other kinds of associations may exist between two closely allied organisms, such as commensalism or mutualism. Endoparasites (such as protozoans and helminths), tend to be found inside the host, while ectoparasites (such as ticks, lice and fleas) live on the outside of the host body. Parasite life cycles often require that different developmental stages pass sequentially through multiple host species in order to successfully mature and reproduce.

Remora are specially adapted to attach themselves to larger fish that provide locomotion and food. Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; and parasitism, where one is harmed and the other benefits. The commensal (the species that benefits from the association) may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected.

Within 7–10 days, the tube can reach a thickness again that will help protect it from predators. The tube production starts in an area around the tentacles and continues in a ring formation down the body of the anemone, meaning it has an open end in the basal region. Additionally, since there is no limit to how far the anemone can lower itself into its tube, it can use this as a means to escape predation. The Phoronid worm species Phoronis australis has an obligate commensalism relationship with C. braziliensis, where it gets a substrate, food, and protection from predation from the anemone.

A plant is said to be a hyperaccumulator if it can concentrate the pollutants in a minimum percentage which varies according to the pollutant involved (for example: more than 1000 mg/kg of dry weight for nickel, copper, cobalt, chromium or lead; or more than 10,000 mg/kg for zinc or manganese).. This capacity for accumulation is due to hypertolerance, or phytotolerance: the result of adaptative evolution from the plants to hostile environments through many generations. A number of interactions may be affected by metal hyperaccumulation, including protection, interferences with neighbour plants of different species, mutualism (including mycorrhizae, pollen and seed dispersal), commensalism, and biofilm.

Exactly how these associations evolve also remains unclear. In studying the coevolution of myrmecophilous organisms, many researchers have addressed the relative costs and benefits of mutualistic interactions, which can vary drastically according to local species composition and abundance, variation in nutrient requirements and availability, host plant quality, presence of alternative food sources, abundance and composition of predator and parasitoid species, and abiotic conditions. Because of the large amounts of variation in some of these factors, the mechanisms that support the stable persistence of myrmecophily are still unknown. In many cases, variation in external factors can result in interactions that shift along a continuum of mutualism, commensalism, and even parasitism.

From this perspective, animal domestication is a coevolutionary process in which a population responds to selective pressure while adapting to a novel niche that included another species with evolving behaviors. Commensal pathway animals include dogs, cats, fowl, and possibly pigs. The domestication of animals commenced over 15,000 years before present (YBP), beginning with the grey wolf (Canis lupus) by nomadic hunter-gatherers.

In a symbiotic relationship, the Agalega Island Day GeckoAgalega Island Day Gecko - Phelsuma borbonica agalegae (Phelsuma borbonica agalegae) feeds off the insects trapped in the viscous, though thin, sap while depositing its vitamin-rich droppings at the base of the tree. Though this may seem to more resemble commensalism than not, the droppings do in fact provide a registrable gain for the cheval tree, though it is not nearly as great as the free and ample sustenance gained by the gecko. Scientists have yet to come up with a satisfactory explanation for this strange "selflessness" on the cheval's behalf, and have set up a research station in the Agalega town of Vingt CinqGovernment of Mauritius for further study.

We may even speak of devices in symbiotic relationships, where devices are somehow "helping" each other in their goals. The notions of mutualism, commensalism, endosymbiosis and ectosymbiosis may then be interpreted for a device ecology with devices of different forms, functionalities and sizes; other relationships can be defined . This also means that devices within a device ecology can affect each other through their behavior. Device ecology relates to the notion of social devices, using the word "social" to describe devices that are capable of interacting with one another, and relates to smart devices, which refers to devices with capabilities to interact with one another and with users in an intelligent context-aware manner.

Remoras (also called suckerfish) can swim freely but have evolved suckers that enable them to adhere to smooth surfaces, gaining a free ride (phoresis), and they spend most of their lives clinging to a host animal such as a whale, turtle or shark. However, the relationship may be mutualistic, as remoras, though not generally considered to be cleaner fish, often consume parasitic copepods: for example, these are found in the stomach contents of 70% of the common remora. Many molluscs, barnacles and polychaete worms attach themselves to the carapace of the Atlantic horseshoe crab; for some this is a convenient arrangement, but for others it is an obligate form of commensalism and they live nowhere else.

Wolbachia bacteria within an insect cell Long-term coevolution sometimes leads to a relatively stable relationship tending to commensalism or mutualism, as, all else being equal, it is in the evolutionary interest of the parasite that its host thrives. A parasite may evolve to become less harmful for its host or a host may evolve to cope with the unavoidable presence of a parasite—to the point that the parasite's absence causes the host harm. For example, although animals parasitised by worms are often clearly harmed, such infections may also reduce the prevalence and effects of autoimmune disorders in animal hosts, including humans. In a more extreme example, some nematode worms cannot reproduce, or even survive, without infection by Wolbachia bacteria.

There is also crosstalk between macrophages and ILC3s, via RORγt driven GM-CSF production, that is dependent on microbial signalling, and the production of IL-1β by macrophages. A deficiency in dietary vitamin A results in abnormally small numbers of ILC3s, and therefore a reduction of IL-22 production, and higher susceptibility to infection. Conversely, retinoic acid suppresses ILC2 proliferation by down regulating IL-7Ra, and deprivation of vitamin A has been shown to enhance ILC2- mediated resistance to helminth infection in mice. ILC3s therefore form a network of interactions to maintain intestinal homeostasis, between the microbiome, intestinal epithelium, neuro-glial cells, and other immune cells. LTi cells are present in Peyer’s Patches, and lymphoid follicles, interacting with B cells facilitating IgA production, which promotes host commensalism with the local microbiota.

The paradox of the plankton results from the clash between the observed diversity of plankton and the competitive exclusion principle, also known as Gause's law, which states that, when two species compete for the same resource, ultimately only one will persist and the other will be driven to extinction. Phytoplankton life is diverse at all phylogenetic levels despite the limited range of resources (e.g. light, nitrate, phosphate, silicic acid, iron) for which they compete amongst themselves. The paradox of the plankton was originally described in 1961 by G. Evelyn Hutchinson, who proposed that the paradox could be resolved by factors such as vertical gradients of light or turbulence, symbiosis or commensalism, differential predation, or constantly changing environmental conditions.Hutchinson, G. E. (1961) The paradox of the plankton. American Naturalist 95, 137-145. More recent work has proposed that the paradox can be resolved by factors such as: chaotic fluid motion;Károlyi, G., Péntek, Á., Scheuring, I., Tél, T., Toroczkai, Z. (2000) Chaotic flow: the physics of species coexistence. Proceedings of the National Academy of Sciences 97, 13661-13665.
