Understanding the dynamics of jumping behavior in desmodus rotundus

Understanding the population ecology of the vampire bat, Desmodus rotundus, in Ecuador. Although there are over 1, species of bats, only three are truly vampires. These obligate blood-feeders have fascinating behaviors and ecologies but suffer from human persecution over fear of rabies transmission.

These three species compose the "true" vampire bats, as opposed to the "false" vampires of the family Megadermatidae and the spectral bat. All three species of Desmodontinae specialize in feeding on the blood of warm-blooded animals.

The upper incisors lack enamelwhich keeps them razor-sharp. The hindlimbs keep the body over the pectoral limbs which are stabilized by the thumbs.

They are able to distinguish different optical patterns and may use vision for long-range orientation. Fossils of this species have been found in Florida and states bordering Mexico.

The common vampire is the most common bat species in southeastern Brazil. In the West Indies, the bat is only found on Trinidad. It prefers warm and humid climates, [13] [14] and uses tropical and subtropical woodlands and open grasslands for foraging.

Feeding[ edit ] A vampire bat being fed at the Buffalo Zoo The common vampire bat feeds primarily on mammalian blood, particularly that of livestock such as cattle and horses. This could be because of the hormones. They must then hide themselves and wait for the blood to digest and some of the water to be excreted before taking off.

They are protective of their host and will fend off other bats while feeding. Mothers leave their young to hunt, and call their young to feed upon returning. Females in a harem have strong social bonds between themselves that are reinforced through interactions in the roost.

The danger is not so much to the human population, but rather to livestock. Joseph Lennox Pawana government bacteriologist in Trinidadfound the first infected vampire bat in March During this asymptomatic stage, the bats continue to behave normally and breed.

There is evidence that it is possible for the rabies virus to infect a host purely through airborne transmission, without direct physical contact of the victim with the bat.

Medical attention should be given to any person who awakens to discover a vampire bat in their sleeping quarters.

It is possible that young children may not fully awaken due to the presence of a bat or its bite.
