This means that the core of the network is made up of highly connected generalists (a pollinator that visits many different species of plant), while specialized species interact with a subset of the species that the generalists interact with (a pollinator that visits few species of plant, which are also visited by generalist pollinators). [5]
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
Pollination is necessary for plants to continue their populations and 3/4 of the plant species that contribute to the world's food supply are plants that require pollinators. [78] Insect pollinators, like bees, are large contributors to crop production, over 200 billion dollars worth of crop species are pollinated by these insects. [ 71 ]
This close relationship is an example of coevolution, as the flower and pollinator have developed together over a long period to match each other's needs. [71] This close relationship compounds the negative effects of extinction , however, since the extinction of either member in such a relationship would almost certainly mean the extinction of ...
When both species gain from their interaction, mutualism develops. The mutualistic link between pollinators and plants is very well illustrated. In this instance, the animal pollinator (bee, butterfly, beetle, hummingbird, etc.) receives nourishment in exchange for carrying the plants' pollen from flower to flower (usually nectar or pollen).
A familiar example of a mutualism is the relationship between flowering plants and their pollinators. [2] [3] The plant benefits from the spread of pollen between flowers, while the pollinator receives some form of nourishment, either from nectar or the pollen itself.
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 ...
For the plant, the pollinizer, this can be an important mechanism for sexual reproduction, as the pollinator distributes its pollen. Few flowering plants self-pollinate ; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of ...
