Furthermore, genetic correlations between embryos grown in the two temperatures were positive, indicating that those genotypes that performed well in elevated temperature also performed well in control temperature. (1997) Sensitivities to global change drivers may correlate positively or negatively in a foundational marine macroalga. Branched chains of beads (vesicles) varying in shape from round to oval depending on habitat. However, PSII performance between genotypes was similar, suggesting that thermal sensitivity is related to processes other than photosynthesis. Hormosira banksii, the most successful intertidal fucoid in the southern hemisphere, usually inhabits only the lower shore.
