Plant-animal interactions are important pathways for the transfer of energy within ecosystems, where both advantageous and unfavorable interactions support ecosystem health. [ 1 ] [ 2 ] Plant-animal interactions can take on important ecological functions and manifest in a variety of combinations of favorable and unfavorable associations, for ...
Pollination has driven the coevolution of flowering plants and their animal pollinators for over 100 million years. See also: Pollination and Plant-pollinator interactions In pollination, pollinators including insects ( entomophily ), some birds ( ornithophily ), and some bats , transfer pollen from a male flower part to a female flower part ...
the ways plants use fruits and edible seeds to encourage animal aid in seed dispersal, and the way corals become photosynthetic with the help of the microorganism zooxanthellae . Mutualism can be contrasted with interspecific competition , in which each species experiences reduced fitness, and exploitation , and with parasitism , in which one ...
Flowering plants and the animals that pollinate them have co-evolved. Many plants that are pollinated by insects (in entomophily), bats, or birds (in ornithophily) have highly specialized flowers modified to promote pollination by a specific pollinator that is correspondingly adapted. The first flowering plants in the fossil record had ...
The same applies to herbivores, animals that eat plants, and the plants that they eat. Paul R. Ehrlich and Peter H. Raven in 1964 proposed the theory of escape and radiate coevolution to describe the evolutionary diversification of plants and butterflies. [42]
A simple example is a stand of equally-spaced plants, which are all of the same age. The higher the density of plants, the more plants will be present per unit ground area, and the stronger the competition will be for resources such as light, water, or nutrients.
Biocommunication of animals may include vocalizations (as between competing bird species), or pheromone production (as between various species of insects), [4] chemical signals between plants and animals (as in tannin production used by vascular plants to warn away insects), and chemically mediated communication between plants [5] [6] and ...
A field of study has emerged regarding urban evolution in which the adaptations of animals and plants to urban environments are studied. In tropical regions a certain species of lizards, Anolis cristatellus, lives in both urban and natural areas. These lizards climb on tree trunks, fences and the walls of buildings.
