Age Status Effects On Female Silk Production And Male Courtship Response In Dolomedes Scriptus, Joseph Osborne
Age Status Effects On Female Silk Production And Male Courtship Response In Dolomedes Scriptus, Joseph Osborne
Student Scholar Showcase
Female Dolomedes scriptus, the striped fishing spider, serve as model organisms exhibiting pheromone production as a means of chemical signaling. Previous work has shown that male fishing spiders are responsive to female silk, and preferentially court in the presence of silk from mature virgins. In our research, we hypothesized that mature females produced larger quantities of silk than penultimate females in an attempt to elicit greater male mating response. Female spiders of both age statuses were kept for two days in a gridded tank. Sub-sampling of silk lines that crossed a random portion of the grid produced results signifying …

Pseudomonas putida GB-1 is a model organism for the study of manganese oxidation in bacteria, however, the frequency of co-localization of multiple known and suspected manganese oxidizing proteins, as well as their occurrence between species, is unknown. Eight different genes isolated from known manganese oxidizing bacteria (MnxG, MopA, McoA, PputGB1_2552, PputGB1_2553, MoxA, MofA, and Bacillus MnxG) were tested individually using BioPython and BLAST (Basic Local Alignment Search Tool) on multiple genomic databases. BLAST searches had an expect value cutoff of 1e-50, limiting gene homologs to those with high sequence similarity. The abundance of homologous genes across classes of proteobacteria point …
