Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
Some species may only be able to detect north and south, while others may only be able to differentiate between the equator and the poles. Although the ability to sense direction is important in migratory navigation, many animals have the ability to sense small fluctuations in earth's magnetic field to map their position to within a few kilometers.
Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was an English electrical engineer, known as the "Father of Maglev" [1] for his development of the linear induction motor and maglev rail system after Hermann Kemper.
Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
While human activities are causing a loss of much of the world's biodiversity, amphibians appear to be suffering much greater effects than other classes of organism. Because amphibians generally have a two-staged life cycle consisting of both aquatic ( larvae ) and terrestrial ( adult ) phases, they are sensitive to both terrestrial and aquatic ...
Agalychnis lemur, the lemur leaf frog or lemur frog, is a species of frog in the subfamily Phyllomedusinae. [ 3 ] [ 4 ] It is found in Costa Rica, Panama, and adjacent northwestern Colombia. [ 3 ] It is classed as Critically Endangered and threatened by the fungal disease chytridiomycosis .
The boreal chorus frog (Pseudacris maculata) is a species of chorus frog native to Canada from central Quebec to eastern British Columbia and north to the Northwest Territories and the southern portion of the Yukon. [2] It occurs in the USA throughout Montana, northwestern Wisconsin, northeastern Arizona, northern New Mexico, and southwestern Utah.
This means that they leave their eggs fully formed, skipping the tadpole stage (an unusual life cycle shared by a few other frog genera, e.g. Eleutherodactylus, Arenophryne, and other members its genus). [citation needed] Their closest relatives, among the few who share most of the turtle frog's traits, are sandhill frogs and forest toadlets. [3]
