evolution of bat pollination: a phylogenetic perspective | Annals of Botany | Oxford Academic
During the day, honey bees and other insects work to pollinate the flowers that flourish in the sunlight, but once darkness falls bats come out of. The ratio between bat-pollinated and hummingbird-pollinated species is 0n24 at the lowland site and review the relationship between flowers and bats in the. Zoophily is a form of pollination whereby pollen is transferred by animals, usually vertebrates These plant-animal relationships are often mutually beneficial because of the food source provided in exchange for pollination. Plants pollinated by bats often have white or pale nocturnal flowers that are large and bell shaped.
Published on June 18, Written by Merrill Read Plants don't just simply grow, they have a lot of help. Whether it's sunlight, rich soil, or a good rain storm, there are plenty of support systems that help plants grow all over the world.
For a lot of plants, a vital support system is bats.

Taubert There are more than species of flowering plants that rely on bats as either their major or exclusive pollinators. Some of these plants include agave which are harvested to supply the multimillion dollar tequila industrybananas, and balsa trees which produce the world's lightest timber.
In fact, the relationship between bats and agave are so strong that bat populations fluctuate in size in accordance with the success of agave.
In order for plants to reproduce, pollen must be carried from the male stamen to a female pistil within a plant. Unfortunately, plants can't meet up easily as they are rooted to the ground, so they rely on others such as hummingbirds, bees, and bats to move their pollen for them.
The bat pollination process: Most bat species that pollinate flowers inhabit Africa, Southeast Asia, and the Pacific Islands, although bat pollination occurs over a geographically wide range. Many flowers are dependent on bats for pollination, such as the flowers which produce mangoes, bananas, and guavas Celebrating Wildlife Bat pollination is an integral process in tropical communities with tropical plant species completely, or partially, dependent on bats for pollination Heithaus Also, it has been noted that outcrossing introducing unrelated genetic material into a breeding line by bats increases genetic diversity and is important in tropical communities Heithaus Plants pollinated by bats often have white or pale nocturnal flowers that are large and bell shaped.
Many of these flowers have large amounts of nectar, and emit a smell that attracts bats, such as a strong fruity or musky odor Gibson Bats use certain chemical cues to locate food sources.
They are attracted to odors that contain esters, alcohols, aldehydes, and aliphatic acids Gibson The banana bat Musonycteris harrisoni is a nectarivorous species found only on the Pacific coast of Mexico. It has a very small geographic range and is distinguishable by its extremely long nose.
Bats Love to Pollinate
The long snout and tongue, one tongue recorded as measuring 76mm, allows this bat to feed on the nectar of long tubular flowers. This bat species is small, with the head and body length ranging from 70 to 79mm.Love tequila, love pollinating bats!
The wild banana flower is elongated with a purple color Tellez Pollination by other mammals[ edit ] Non-flying mammals to distinguish them from bats have been found to feed on the nectar of several species of plant.
Though some of these mammals are pollinators, others do not carry or transfer enough pollen to be considered pollinators Johnson This group of non-flying pollinators is mainly composed of marsupials, primates, and rodents Johnson Well-documented studies of non-flying mammal pollination now involve at least 59 species of mammal distributed among 19 families and six orders Carthewa As ofthere were 85 species of plants from 43 genera and 19 families which were visited by these mammals Carthewa In many cases, a plant species is visited by a range of mammals.
Two examples of multiple mammal pollination are the genus Quararibea which is visited by 12 species and Combretum which is visited by 8 Carthewa Plant species that feed non-flying mammals will often exhibit similar characteristics to aid in pollination. The flowers are often large and sturdy, or are grouped together as multi-flowered inflorescences.
Many non-flying mammals are nocturnal and have an acute sense of smell, so the plants tend not to have bright showy colors, but instead excrete a pungent odor. Plants will often flower profusely and produce a large amount of sugar-rich nectar. These plants also tend to produce large amounts of pollen because mammals are larger than some other pollinators, and lack the precision smaller pollinators can achieve Carthewa Animals with more precision, such as bees or other insects with a proboscis, can pollinate small flowers with less pollen necessary.
This means that a plant will require more pollen for a larger mammal pollinator. One example of a symbiotic relationship between a plant and its animal pollinators is the African Lily, Massonia depressaand some rodent species of the Succulent Karoo region of South Africa.
