THE USE OF CHEMICAL CUES BY SARGASSUM SHRIMPS LEANDER TENUICORNIS AND LATREUTES FUCORUM IN ESTABLISHING AND MAINTAINING A SYMBIOSIS WITH SARGASSUM ALGAEUnknown Date (has links)
A mutualistic symbiosis exists between the alga Sargassum spp. and two shrimp species, L. tenuicornis and L. fucorum. But little is known about how the shrimp locate their host alga. Both visual and chemical cues are potentially available. Visual cues would be presumably restricted at night but chemical cues are potentially available continuously. Additionally, a previous study has looked at both cue variables with results that are mixed. This current research elaborates on the previous study in an attempt to fully understand Sargassum shrimp chemoreception. A y-maze and four-chambered apparatus were used to test if the shrimp were able to detect Sargassum cues, conspecific cues, and Dimethylsulfoniopropionate (DMSP) cues. Neither shrimp species showed a strong directional response to any of the chemical cues, but the Sargassum and DMSP cues did cause more shrimp to exhibit searching behavior. Additionally, several differences in response between male and female shrimp were found for each cue. A weaker dilution of DMSP was tested in an attempt to determine sensitivity of L. fucorum shrimp to the chemical cue. This weaker dilution also caused L. fucorum to exhibit searching behavior, but the sensitivity to the cue was not found and further research is needed to fully answer this question. These results show the shrimp are able to detect chemical cues in their environment and help determine more accurately the role of chemoreception in initiating and maintaining this shrimp/algal association. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection

Herman L. Midlo: Social Ally in Louisiana Religious Civil RightsTaylor, Kenneth William-Moran 23 May 2019 (has links)
The study of social allies in the field of American Civil Rights and Liberties History is largely an underappreciated aspect of this historical era. This work argues that social allies and their stories are worthwhile histories that are beneficial to the study of American Civil Rights and Liberties using Louisiana lawyer Herman Lazard Midlo as a case study. Midlo worked as a Louisiana lawyer from the 1930s to 1960s and fought tirelessly for the religious liberties of the Jehovah’s Witness community in the state. His story shows how beneficial and consequential the actions of social allies have had and can have on the protection and expansion of civil rights and religious liberties.
