A New Spin On The Bacterial Flagellum: Its Normal Niche And Displacement, Alan L. Gillen Aug 2022

A New Spin On The Bacterial Flagellum: Its Normal Niche And Displacement, Alan L. Gillen

Faculty Publications and Presentations

Antoni van Leeuwenhoek observed individual living cells for the first time in history in 1674. Two years later, he noted microbes with long, thin appendages protruding from globular cells that seemed to provide locomotion, like “little feet” as they moved in drops of water. He gave credit to God in his writings over these new moving wonders. These appendages are now known as flagella (fig. 1), meaning “little whips” (from Latin).

More than 300 years later, Dr. Michael J. Behe used the flagellum and its nanomotor to introduce the concept of “irreducible complexity”—the idea that a structure is so complex …

Faculty Publications and Presentations

The Peaks of Otter Salamander (Plethodon hubrichti; POS) is a montane species found at elevations above 442 m within a 117 km2 area of the Blue Ridge Mountains in central Virginia. In allopatric areas (areas without the Eastern Red-backed Salamander, P. cinereus, a known competitor), POS body condition was hypothesized to decline both above and below some optimal elevation. Decreased condition at lower elevations would most likely be due to increased temperatures and lower relative humidities, which may adversely affect the ability of salamanders to forage effectively on vegetation due to desiccation risk. Decreased condition at elevations above …

Why Are There So Many Mosquitoes?, Alan L. Gillen, Savannah Childs, Megan Goin, Karly Mckinney

Faculty Publications and Presentations

Mosquitoes have been challenging man and animals alike since the fall.Mosquitoes number in the trillions worldwide. Not only is the mosquito a nuisance with the constant buzz around your ear, they also are the primary vector of many dangerous diseases including the West Nile Virus (WNV). WNV has become a more prominent mosquito-transmitted disease in the United States and more specifically in Colorado, Texas, and other states in the Midwest. While commonly found in the genus Culex, WNV and other diseases can be found in differentgenera of mosquito, including Aedes and Anopheles. While these two are not themost common regarding …
