Biological interactions

The ways in which one species can affect another.

Neutralism

A rare type of interaction where two species have no impact on each other.

Protocooperation

A relationship where both populations benefit from each other, but do not depend on each other for survival.

Mutualism

A relationship where both populations benefit from each other and depend on each other for survival.

Commensalism

A relationship where one species benefits without any impact on the other.

Competition

The interaction between species where they compete for resources.

Allelopathy

A type of competition where one organism produces chemicals that negatively influence another organism.

Mimicry

When one species evolves to look like another species.

Amensalism

A relationship where one species has a negative impact on another species, while the other species is unaffected.

Predation

When one organism consumes another organism.

Abundance

The population density of a species.

Coexistence

The ability of different species to live together in the same geographical area.

Resource partitioning

When species live together but have clear barriers where they split resources.

Character displacement

When species change their characteristics depending on competition.

Spatial competition

Competition that allows a greater number of species to coexist on limited resources.

Polyspecific associations

Different species living alongside each other and actively interacting.

Stenophagy

When a species depends on a specialist niche and a specific factor for survival.

Predator impact

The impact of predators on the distribution of prey species in an area.

Keystone species

A species whose removal leads to the dominance of other species.

Parasitism

A relationship where one organism benefits at the expense of another organism.

Micro parasites

Small parasites such as viruses, bacteria, and protozoa.

Macro parasites

Larger parasites such as worms, ticks, fleas, and lice.
