Acropora aspera fecundity in colonies experimentally heat-stressed during late stages of gametogenesis (Heron Island, Southern Great Barrier Reef)

The dataset contains information of Acropora aspera coral fecundity in gravid colonies exposed to heat-stress during late stages of gametogenesis. All experimental branches originate from the Wistari Reef slope, in the southern Great Barrier Reef (Capricorn Bunker). \nPilot study/short-term experiment: From September to December 2021, 9x Acropora aspera donor colonies were selected, tagged, and sampled on the Wistari reef slope (~5m depth). From each colony, 9x branches of approximately 20cm length were collected and brought to the Heron Island Research Station. The coral branches were exposed to 3x different temperature treatments: \n-\tControl temperatures for three weeks prior spawning \n-\t+1C above average temperatures for 2 weeks prior spawning\n-\t+1C above average temperatures for 1 week prior spawning \nEach of the temperature treatments were replicated in 9x tanks. Each of the x81 sub-colonies were assigned to one treatment with care to have 3x branches of each genotype in each treatment and x3 different genotypes in each tank. Samples (
