Overview

We as humans are a part of the class Mammalia, a distinct class of animals that are recognized by hair on their bodies and mammary glands to produce milk. Bats are the only mammal that is capable of prolonged flight but maintains the other identifiable traits of the mammal. The Black Flying Fox (Pteropus alecto) is a species of bat is found in Oceania countries of Australia and Papua New Guinea. It is also found in In the Southeast Asian country of Indonesia. The Black Flying Fox is characterized by a high amount of genetic diversity and its ability to survive extreme natural disasters through adaptation. This information is provided by the article, “Population genomic analysis reveals distinct demographics and recent adaptation in the black flying fox (Pteropus alecto)”. In this article it cites direct evidence for how these unique bats have high genetic diversity compared to other mammals and how they likely survived a possible extinction event thousands of years ago.

This time Batman needs help … with whitenose syndrome

This time Batman needs help … with whitenose syndrome

Many people forget that bats are not just there for inspiring big-name superheroes. Bats play a critical role in pollination of many commercial products throughout the world such as bananas and peaches just to name a few. Bats also play an essential role in crop growth by maintaining the populations of common pests. However, bats in North America are in a time of crisis and it all began with fungus. Pseudogymnoascus destructans (P. destructans), a cold loving fungus, is able to grow in hibernating bats when their bodies reach a temperature of 39 to 68 degrees. This fungus grows and makes the bats ill and spiked a recent decline in North American bats. The disease was named White-nose syndrome due to the fungal growth resulting in white substance on the muzzle of the bats. White-nose syndrome has specifically hurt the North American little brown myotis bat which has been driven to the endangered species list in under ten years due to the syndrome.
