Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
Selfing syndrome refers to plants that are autogamous and display a complex of characteristics associated with self-pollination. [1] The term was first coined by Adrien Sicard and Michael Lenhard in 2011, but was first described in detail by Charles Darwin in his book “The Effects of Cross and Self Fertilisation in the Vegetable Kingdom” (1876), making note that the flowers of self ...
Mechanical isolation also occurs in plants and this is related to the adaptation and coevolution of each species in the attraction of a certain type of pollinator (where pollination is zoophilic) through a collection of morphophysiological characteristics of the flowers (called pollination syndrome), in such a way that the transport of pollen ...
One such syndrome is "buzz pollination" (or "sonication"), where a bee must vibrate at a certain frequency in order to cause pollen to be released from the anthers. [24] In zoophily, pollination is performed by vertebrates such as birds and bats, particularly, hummingbirds, sunbirds, spiderhunters, honeyeaters, and fruit bats.
In gametophytic self-incompatibility (GSI), the SI phenotype of the pollen is determined by its own gametophytic haploid genotype. This is the most common type of SI. [4] Two different mechanisms of GSI have been described in detail at the molecular level, and their description follows.
The Coolidge effect is a biological phenomenon seen in animals, whereby males exhibit renewed sexual interest whenever a new female of reproductive availability is introduced, even after sex with prior but still available sexual partners.
Blake Lively stepped out for a red carpet comeback as her legal battle with Justin Baldoni continues. The actress attended the star-studded live taping of SNL50: The Anniversary Special in New ...
Anthecology, or pollination biology, is the study of pollination as well as the relationships between flowers and their pollinators. [1]: 8 Floral biology is a bigger field that includes these studies. Most flowering plants, or angiosperms, are pollinated by animals, and especially by insects. [2]
