Density Dynamics Of Endosymbiotic Wolbachia Bacteria In The Drosophila Host, Zinat Sharmin
FIU Electronic Theses and Dissertations
Wolbachia pipientis is one of the most widespread bacterial endosymbionts, infecting mites, crustaceans, and filarial nematodes as well as about half of all insect species. These bacteria cause many neglected human diseases that include African river blindness and lymphatic filariasis affecting over 100 million people worldwide. Interestingly, Wolbachia also suppress the transmission of viruses such as Dengue, Chikungunya, and Zika. In most reported cases, Wolbachia antiviral activity is a density-dependent effect, with high Wolbachia density conferring the strongest viral suppression. However, little is currently known about how Wolbachia load is controlled within the insect host. A small number of studies …

Functional Regionalization In The Fly Eye As An Adaptation To Habitat Structure, Carlos A. Ruiz
FIU Electronic Theses and Dissertations
With over 150,000 described species, flies constitute one of the most species-rich groups of animals on earth, and have managed to colonize almost every corner of it. Part of their success comes from their amazing flying skills, which are strongly tied to their visual capabilities. To navigate fast and accurately through their habitats, they must be able to process the inordinate amounts of visual information necessary to sort obstacles, avoid predators and remain on course. Surprisingly, despite their tiny brains, flies have no problem in processing all that information to generate correcting maneuvers in just about 30 ms. To this …
