GLOSSOPHAGA SORICINA PDF

More information Other Comments Glossophaga soricina has several morphological features that have been interpreted as adaptations for nectivory: a long, extendable tongue for probing into flowers; divergent hair scales that hold pollen grains; and specializations in digestive physiology to facilitate digestion of nectar and pollen.

The lower incisors are relatively large which fill the gap between the canines. The presphenoid ridge is evident and prominent throughout. A combination of these features can help distinguish G. There are five subspecies of Glossophaga soricina which include G.

The ovulation of G. Ovulation usually alternates between the two ovaries. Ovulation and menstruation usually take place around the same time. After fertilization occurs, the embryo has reached the two-cell stage of development by day 2 or 3. The eight-cell stage happens within 5- 7 days. It divides to the cell stage by day 8, and reaches the blastocyst stage by the 10th day.

The blastocyst is implanted in the uterotubal junction during days 14 Alverez Also, research shows that copulation does not precede ovulation, but most likely happens at the same time Hamlett b. Ecology and Behavior: Glossophaga soricina inhabits caves, tunnels, abandoned mines, hollow trees and logs, buildings, culverts, and beneath bridges. Their colonies usually host both sexes, but the females and their offspring form maternity colonies during certain times of the year.

The diet of G. Glossophaga soricina has a night activity pattern that is bimodal; its peak activity time is right after dark and right before dawn. They also help pollinate because the pollen sticks to their wings, body, and head and is transferred between plants. These aggressive displays increase as food becomes harder to find.

Research also showed that females shared their feeding areas with their immature offspring. Remarks: Except for primates, most mammals have dichromatic vision, which limits color perception. Only a short time ago ultraviolet vision was found to be possessed by mammals, in certain marsupials and rodents.

Bats mainly use echolocation, but also use color vision sometimes. Recently, in research done by Winter, Lopez, and Von Helversen they showed that Glossophaga soricina is color-blind but sensitive to ultraviolet light readings down to nm.

They discovered that the excitation of the beta-band of the visual pigment is thought to cause ultraviolet sensitivity Winter Literature Cited: Alverez, J. Mammalian Species, No. November Cockrum, E.
