The Southern Resident Orcinus Orca Population In Puget Sound: Hypotheses On Population Ratios And The Effects Of The Capture Era On Behavior Of The Whales, Beth Phillips
WWU Honors College Senior Projects
This project set out to assess the population status of the southern resident community of Orcinus orca, the killer whale, in Puget Sound. The current number of whales in the community is 84, down from 97 in 1995, and it has been hypothesized that their numbers will continue to decline in the future. The study focused specifically on the residual effects of the capture era in the 1960’s and 1970’s that systematically cropped immature male and female killer whales from the southern resident community. Then, the behavioral adaptations that the killer whales appear to be making in response to …

Inhibition Of Microbial Growth By Eelgrass Extracts, Emily E. (Emily Elizabeth) Lambert
WWU Honors College Senior Projects
Eelgrass extracts from Zostera marina and Zostera japonica were tested against bacterial isolates for antibacterial activity. Bacterial isolates that exhibited sensitivity to the eelgrass extracts were also tested against nine pure phenolics, and one complete mixture, for inhibition. Isolated marine bacteria and one marine lab culture were sensitive to both eelgrass extracts. Antibacterial activity was also found with the samples of nine pure phenolic acids, and one mix of these nine, known to be produced in Zostera. It is likely the phenolic acids in eelgrass extracts have antibacterial effects.
