Additionally, some species have been found to perform cooperative behaviors that may at first sight seem detrimental to their own evolutionary fitness. For example, when a ground squirrel sounds an alarm call to warn other group members of a nearby coyote, it draws attention to itself and increases its own odds of being eaten. [5]
Pairwise or specific coevolution, between exactly two species, is not the only possibility; in multi-species coevolution, which is sometimes called guild or diffuse coevolution, several to many species may evolve a trait or a group of traits in reciprocity with a set of traits in another species, as has happened between the flowering plants and ...
Plants are considered domesticated when their life cycle, behavior, or appearance has been significantly altered as a result of being under artificial selection by humans for multiple generations (see the main article on domestication for more information). Thousands of distinct plant species have been domesticated throughout human history.
Mutualism is an interaction between two or more species, where species derive a mutual benefit, for example an increased carrying capacity. Similar interactions within a species are known as co-operation. Mutualism may be classified in terms of the closeness of association, the closest being symbiosis, which is often confused with mutualism.
For example, mutualistic interactions are vital for terrestrial ecosystem function as: about 80% of land plants species rely on mycorrhizal relationships with fungi to provide them with inorganic compounds and trace elements. [7] estimates of tropical rainforest plants with seed dispersal mutualisms with animals range at least from 70% to 93.5% ...
Humans evolved from chimp-like ancestors with a similar hierarchical social structure (i.e., open dominance hierarchy that is male-dominated) Males were highly motivated to achieve high rank. The short term reward of this was the position itself and the long-term reward was reproductive success, which resulted from greater access to mates with ...
Many animal species cooperate with each other in mutual symbiosis.One example is the ocellaris clownfish, which dwells among the tentacles of Ritteri sea anemones.The anemones provide the clownfish with protection from their predators (which cannot tolerate the stings of the sea anemone's tentacles), while the fish defend the anemones against butterflyfish (which eat anemones)
Phytosociology, also known as phytocoenology or simply plant sociology, is the study of groups of species of plant that are usually found together. Phytosociology aims to empirically describe the vegetative environment of a given territory. A specific community of plants is considered a social unit, the product of definite conditions, present ...
