Mucuna Holtonii
''Mucuna holtonii'' is a species of plant in the bean family, which is pollinated by bats. Bats are able to detect if the flowers have nectar using echolocation.*D. von Helversen and O. von Helversen. "Object recognition by echolocation: a nectar feedingbat exploiting the flowers of a rain forest vine". in Journal of Comp. Physiol. A. (2003) 189: 327-336.von Helversen & von Helversen (1999Acoustic guide in bat-pollinated flower''Nature Nature is an inherent character or constitution, particularly of the Ecosphere (planetary), ecosphere or the universe as a whole.

After an initial bat visit during which nectar is removed, the petals are arranged in a different manner (altering the shape of the flower). As a result, the unique "echo fingerprint" of petal arrangement informs the bat whether nectar is present or absent. It is thought that the p ...

Harold Norman Moldenke
Harold Norman Moldenke, also known as simply Moldenke (1909–1996) was an American botanist/taxonomist. His expertise is largely in the study of Verbenaceae, Avicenniaceae, Stilbaceae, Dicrastylidaceae, Symphoremaceae, Nyctanthaceae and Eriocaulaceae. Early life Moldenke was the son of Charles E. and Sophia (Heins) Moldenke. His father was a noted Egyptologist whose translation of the hieroglyphics on Cleopatra's Needle he reprinted. Harold was born in Watchung, New Jersey, in 1909, and earned a bachelor's degree from Susquehanna University in 1929. Moldenke's career started at the New York Botanical Garden, a place he maintained a close relationship with (donating many educational materials to its library). There, he worked as a Research Fellow and part-time assistant in 1929. He taught a course in Systematic Botany for gardeners there as well. For 16 years, he worked as the assistant and associate curator under Henry A. Gleason. When Moldenke served in the Civili ...

Animal Echolocation
Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the Echo (phenomenon) , echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for animal navigation , navigation, foraging, and predation, hunting prey. Echolocation calls can be Frequency modulation, frequency modulated (FM, varying in pitch during the call) or constant frequency (CF). FM offers precise range discrimination to localize the prey, at the cost of reduced operational range. CF allows both the prey's velocity and its movements to be detected by means of the Doppler effect. FM may be best for close, cluttered environments, while CF may be better in open environments or for hunting while perched. Echolocating animals include mammals, especially odontocetes (toothed whales) and some bat species, and, using s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
