Effects of the environment on the reproduction and early performance of the habitat-forming kelp Ecklonia radiata

Margie Mohring

My thesis research examined the effects of environmental conditions on the reproductive ecology of the brown habitat-forming kelp Ecklonia radiata.  My work included the first documentation of reproductive seasonality for E. radiata, as well as biogeographic comparisons of thermo-tolerance and gametophyte performance [Thesis abstract].

Supervisors: Thomas Wernberg, Gary Kendrick

A: Zoospores and newly germinated gametophytes 18 hrs after release. B, C, D: Gametophytes at 3, 6 and 12 days after zoospore release. E, F: Female and male gametophytes at 18 days. G: Sporophyte (fertilised) after 22 days of culture since zoospore release.

I completed my Bachelor of Applied Science majoring in Marine Science and Management at Southern Cross University in 2006. I then completed my Honours Degree in Marine Science with the University of New England in New South Wales examining ecological relationships between sub-tidal gastropod molluscs and habitat and benthic structure. I have a passion for marine science and conservation, and am a highly experienced (>400 hours), ADAS-qualified scientific diver.
