Pallid bats vs Arizona Bark Scorpions

I don’t know about you, but I am terrified of scorpions.  As if scorpions were not spooky enough, the Arizona bark scorpion (Centruroides sculpturatus) is the most venomous scorpion in North America. Gulp. Enter the pallid bat. Clearly not as intimidated, pallid bats (Antrozous pallidus) often dine on Arizona bark scorpions. Researchers at the University of California at Riverside wanted to examine whether the bats were truly resistant to the […]

Attempts to save Houston’s bats

Got bugs? Get a bat. As many species of bats are insectivores, they help keep insect populations in check. Hurricane Harvey has been devastating to people, animals and property. So it probably comes as no surprise that there are many volunteers dedicating their time to saving animals displaced by Hurricane Harvey as well. From squirrels, cats and dogs to…you guessed it…bats. It turns out that bats are not very good […]

White Nose Syndrome – What do we know now?

You may recall prior Lifelines posts discussing the devastating effects of white nose syndrome (WNS) in bats. WNS, Pseudogymnoascus destructans is a fungus responsible for the deaths of millions of North American bats over the last ten years. In a new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, Dr. Craig Willis examined the effects of repeated arousals from hibernation induced by the fungal infection. […]

Using feces to identify species

According to a press release from Northern Arizona University, Drs. Faith Walker and Carol Chambers at the Bat Ecology & Genetics Lab have developed a system called Species From Feces to identify bat species from guano collected in field locations such as mines, caves, bridges, etc. The system takes advantage of DNA sequencing technology and an assay to look for genetic identifiers unique to different species using DNA barcodes. The sequences can then […]

Ever wonder why bats sleep upside down?

Just in time for Halloween: Besides being an excellent way to avoid predators, roosting or hanging upside down is optimal for taking off into flight. Bats are not able to launch into flight from an upright position because their wings do not generate sufficient lift while at a dead stop. Additionally, their hindlegs are rather underdeveloped, so they are not able to run to generate lift for take-off. Instead, bats […]
