The Interference competition is a direct form of competition where an organism actively interferes with another organism's ability to obtain it's resource. Although there may be plenty of the resource, Interference competition happens when one organism devises a way of interfering with another organism’s access to mutually desired resources. For example, walnut trees produce deadly toxins in the soil, and pine trees change the natural pH of the soil to keep competitors at bay. Interspecific competition is a key process affecting resource acquisition, growth and survival of organisms within and among habitats. Manipulative experiments have shown that competition between adults, whether exploitative or interference, leads to exclusion of inferior resource competitors from some habitats when intense –.

Interference competition

The incorporation of interference into niche theory clarifies the competitive phenomenon of unstable equilibrium points, excess density compensation on islands, competitive avoidance by escape in time and space, the persistence of the "prudent predator," and the magnitude of the difference between the size of a species' fundamental niche and its realized niche. Interference competition has been widely observed in nature either between species or within species. Dominance in interference competition is often determined by differences in … Similarly, we quantified the level of interference competition as the number of all sympatric avian predator species that are active during the period typical for the focal order. (iv) We then tested whether the level of exploitation and interference competition predicted between-assemblage variation in the number of time-shifted species. Ant-hemipteran mutualism has been well documented, and many studies have reported the interference competition between ant species for the mutualism. However, little is known on how this interference competition impacts the reciprocally beneficial association. Previous studies demonstrated that the invasive mealybug Phenacoccus solenopsis (Tinsley) has established close mutual relationship The importance of interference competition, where individuals compete through antagonistic traits such as the production of toxins, has long been recognized by ecologists, yet understanding how these types of interactions evolve remains limited.

The magnitude of interference is linked to that of attack efficiency: when both levels are intermediate, populations are maximally stable and have high competitive ability. Competition is a type of interaction wherein both the species compete for the same limited resources. Competition is considered to be harmful for both the competing organisms. Competition can be A linear model of interspecific competition with separate parameters for exploitation and interference is deduced. Interference is assumed to have a cost and an effect. The interfering species realizes a “profit” if some resources, which the species interfered against would have utilized, are made available as a result of the interference.
