| Outline of Annual Research Achievements |
I have pursued the goals summarized in my previous report (Strategy for Future Research Activity). Specifically, I have: (1) Characterized the behavioral effects of satiety on the feeding behavior of the jellyfish Cladonema, as well as their temporal dynamics and tissue specificity; (2) Characterized the effects of a putative satiety peptide and carried out immunohistochemistry to determine its expression and (3) Expanded the set of candidate peptides using proteomics. Additionally, I have begun looking into the effects of satiety on other jellyfish behaviors, such as locomotion.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
While there have been technical setbacks for some experiments, there is good progress in most, and I am currently drafting a manuscript focusing on a detailed characterization of satiety in jellyfish.
|
| Strategy for Future Research Activity |
As some experiments have been concluded while others are still ongoing (with promising outcomes), I will focus my efforts towards wrapping up all experiments and the publication of the new results.
|
| Causes of Carryover |
The funds will be used for completion of ongoing experiments, experimental animal maintenance and to cover publication fees.
