Experimental results on swimming behaviors of four species of cnidarian hydromedusae at Friday Harbor in 2012 (Jellyfish predation in turbulence project)

Expand/Collapse All

Description

Swimming behaviors of four species of cnidarian hydromedusae (Aequorea victoria, Mitrocoma cellularia, Stomotoca atra, Aglantha digitale) exposed to two flow conditions in a laboratory turbulence generator - still water and turbulent (ε ~10-7 m2 s-3) were examined.

A two-way ANOVA was used to test for significant effects of species, flow level (still and turbulent) and their interaction on swimming behavior parameters, including depth in the tank, observed speed, acceleration, NGDR, and time spent swimming. Raw data that did not meet the assumption of normality were square root transformed. Proportion data (NGDR, and time spent swimming) that did not meet the assumption of normality were arcsine square root transformed, which is appropriate for proportion data (Zar, 1999).

Data Processing Description

BCO-DMO Processing:

- added conventional header with dataset name, PI name, version date
- renamed parameters to BCO-DMO and BODC standards
- added column 'id'
- shortened post-decimal sigificant digits from 15 to 4
