= Dyacopterus = From Wikipedia, the free encyclopedia

Jump to navigationJump to search Dyacopterus is a genus of megabats. from south-east Asia. It contains three species, namely:


 * Dayak fruit bat, Dyacopterus spadiceus
 * Brooks's dyak fruit bat, Dyacopterus brooksi
 * Rickart's dyak fruit bat, Dyacopterus rickarti

The Dyacopterus Brooksi and the Dyacopterus Rickarti are subspecies of the Dyacopterus Spadiceus. These three bats can be found throughout South-East Asia, specifically in Malaysia, Borneo and Thailand.

Distribution
These three bats can be found throughout South-East Asia, specifically in the forests of Malaysia and Thailand. The Dycaopterus Spadiceus was the first species to be discovered, in 1980. At the time, this was the only Dyacopterus to be discovered. Fourty years later, in 1920, the Dyacopterus Brooksi was discovered. The last to be discovered was the Dyacopterus Rickarti, this species was not discovered for another fourty years as well. It was discovered in 1961.

Characterization
Although all three of these bats fall under the same genus of bats, they are differ in size. The first species, the Dyacopterus Spadiceus, is the smallest of the three. The head of this particular species is the smallest of the three. The species that falls in the middle when it comes to size is the Dyacopterus Brooksi. The Rickarti bats are the largest out of the three species. The Rickarti species is the largest out of the three when it comes to overall body and head size. However, compared to other bats these three are much larger than the others. Spadiceus bats tend to weigh 85- 95 grams when fully grown. Rickarti weigh much heavier and can be 70% larger than both Brooksi and Spadiceus bats. In the middle is the Brooksi bats, they are not much larger than the Spadiceus species. When it comes to size difference between male and female bats, there is no size difference; this characteristic is accurate throughout all three species. All Dyacopterus bats have very short tails which tend to be 10-20% shorter than their bodies.

Appetites
The Dyacopterus genus bats are all Frugivorous. They mainly feed on fruits but they are also herbivores so they do consume plants as well. This is common for many bats in this region as well as throughout the world. When fruit is no longer abundant due to the season or weather these bats tend to focus more on things like pollen and nectar from plants.

Habitat
These three species of bats can be found in locations that have easy access to fruits, plants, and resources needed to survive. Common places include rain forests, caves, and along side rivers. These bats like to spend their time in high branches of trees due to the abundance of fruit. However, their location usually changes based on the weather and where they can find the easiest access to food, so their habitat changes often.

Rarity
These bats are very rare compared to other South-East Asian bats. This is due to the fact that they do not tend to fly low enough to be captured and researched on. Another reason these bats are very rare is because they are endangered. The Dyacopterus Spadiceus bat is the only species that has been captured and researched on. This is because this species as a whole likes to stay high in canopy and subcanopy, making it difficult to be captured. Another reason why these bats are rare because they are endangered. As of 2008, the Dyacopterus Brooksi has been on the endangered species list. This is also the case with the Dyacopterus Rickarti, they are slowly decreasing in population. This is due to climate changes and the tearing down of forests and homes of these bats for residential and commercial areas.
