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.
Treatment of sporotrichosis depends on the severity and location of the disease. The following are treatment options for this condition: [13] Oral potassium iodide; Potassium iodide is an anti-fungal drug that is widely used as a treatment for cutaneous sporotrichosis. Despite its wide use, there is no high-quality evidence for or against this ...
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 ...
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 ...
Such a "pollination syndrome", being due to flower color and orientation controlled by their genetics, ensures reproductive isolation and can be a cause of speciation. [24] Aquilegia petals show an enormous range of petal spur length diversity ranging from a centimeter to the 15 cm spurs of Aquilegia longissima.
The flowers are visited by a wide variety of insects (the generalised pollination syndrome). [10] Some species in the insect order Lepidoptera frequently use the willowherb as their primary larval host-plant, examples including the elephant hawk moth ( Deilephila elpenor ), [ 11 ] bedstraw hawk moth ( Hyles gallii ), and the white-lined sphinx ...
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 ...
A pine with male flowers releasing pollen into the wind. Features of the wind-pollination syndrome include a lack of scent production, a lack of showy floral parts (resulting in small, inconspicuous flowers), reduced production of nectar, and the production of enormous numbers of pollen grains. [4]
