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.
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.
This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. [1] Almost all gymnosperms are anemophilous, as are many plants in the order Poales , including grasses , sedges , and rushes . [ 1 ]
Although the existence of pollinator decline can be difficult to determine, a number of possible reasons for the theoretical concept have been proposed, such as exposure to pathogens, parasites, and pesticides; habitat destruction; climate change; market forces; intra- and interspecific competition with native and invasive species; and genetic alterations.
A syndrome is a set of medical signs and symptoms which are correlated with each other and often associated with a particular disease or disorder. [1] The word derives from the Greek σύνδρομον, meaning "concurrence". [2]: 1818 When a syndrome is paired with a definite cause this becomes a disease. [3]
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 ...
