Summary:
Ctenophores (comb jellies) are prevalent in all oceans and are noted for possessing rapid wound-healing systems. This research sought to facilitate the use of wound healing in the ctenophore Mnemiopsis leidyi as a biological indicator for specific water quality conditions. For Aim I, wound healing rate of M. leidyi in current average water temperature was determined. Twenty ctenophores were collected, wounded, and analyzed via time-lapse photography and statistical analysis. The wound healing rate was determined to be 14 +- 7 um min-1, with rates not changing significantly in speed based on initial wound width or length (independent sample t-test, p=0.051; p=0.478). In the second aim, wound healing rate at increased temperatures (approximately 5C above water temperature at time of collection) was measured. For this aim, fourteen ctenophores were wounded and imaged over time. The wound healing rate was determined to be 12+- 5 um min-1, with rates not changing significantly in speed based on initial wound width or length (independent sample t-test, p=0.081; p=0.132). No significant difference was found between the overall average healing rate of Aim I and Aim II (independent sample t-test, p=0.749). Findings suggest a 5C increase in water temperature, size of wounds, or size of wounded Mnemiopsis leidyi has no significant influence over the animal's average wound healing rate in current average water temperatures.
