A biological interaction is the effect of two species living together in a community on each other in ecology. They might be of the same species (intraspecific interactions) or distinct species (interspecific interactions) (interspecific interactions). These impacts can be short-term, such as pollination and predation, or long-term, such as extinction, and both can have a significant impact on the evolution of the species involved. A symbiosis is a long-term relationship. Mutualism, which benefits both parties, to competition, which is destructive to both partners, is examples of symbioses. Through intermediaries such as shared resources or common opponents, interactions might be indirect. A net impact based on individual effects on both species originating from the interaction can be used to demonstrate this sort of relationship. Non-trophic species interactions, such as habitat change and mutualisms, have been postulated as major drivers of food web topologies in several recent studies. However, it’s uncertain if these findings apply to all ecosystems, and whether non-trophic interactions impact food webs in a random or specific way, depending on trophic levels or functional groupings.
Although biological interactions had previously been researched in isolation, Edward Haskell (1949) proposed an integrative approach to the topic, suggesting taxonomy of “co-actions,” which biologists eventually embraced as “interactions.” Symbiosis is a term used to describe close and long-term connections; mutualistic symbioses are those that benefit both parties.
• Short-term interactions
• Symbiosis: long-term interactions
In ecology and evolution, short-term interactions like as predation and pollination are crucial. These are short-lived in terms of a single interaction: a predator kills and consumes a victim; a pollinator transports pollen from one flower to another; yet they are incredibly long-lasting in terms of their impact on both partners’ evolution. As a consequence, the partners develop together.
Symbiosis: long-term interactions
Mutualism, commensalism, and parasitism are examples of symbiotic relationships between members of two separate species. Whether the species benefit, hurt, or have no influence on one another, any connection between two populations that exist together is symbiotic. Mutualism, commensalism, parasitism, neutralism, amensalism, and competition are the six forms of symbiosis. The degree of advantage or harm they cause to each partner distinguishes them.
Organisms that directly or indirectly control the availability of resources (other than themselves) to other species by producing physical state changes in biotic or abiotic materials are referred to by this term.
• Negative/ Positive
• Relationship in space and time
These interspecies interactions can be seen in a variety of ways. One method is to represent interactions as a network, which identifies the members and the patterns that link them. Species interactions are typically thought of in terms of trophic interactions, or which species feed on which other species. Ecological networks that include non-trophic interactions are now being constructed. Mutualism, commensalism, neutralism, amensalism, antagonism, and competitiveness are six different types of relationships that they can contain.
It might be difficult to see and estimate the fitness costs and benefits of species interactions. The way interactions are viewed has a big impact on the conclusions that follow. Organisms that directly or indirectly control the availability of resources (other than themselves) to other species by producing physical state changes in biotic or abiotic materials are referred to by this term. Beavers, for example, are a type of engineer. Earthworms, trees, coral reefs, and planktonic species are some more examples. Such “interaction modifiers” might be thought of as “network engineers,” meaning that changes in their population density alter interactions between two or more other species.
