Thermal tolerance (ED50) data used to compare previously published regional (Florida Reef Tract, Coral Sea, Red Sea) coral thermal tolerance with Heron Island, Great Barrier Reef values measured in 2022

Abstract:

Variable temperature regimes that expose corals to sub-lethal heat stress have been recognized as a mechanism to increase coral thermal tolerance and lessen coral bleaching. However, there is a need to better understand which thermal regimes maximize coral stress hardening. Here, standardized thermal stress assays were used to determine the relative thermal tolerance of three divergent genera of corals (Acropora, Pocillopora, Porites) originating from six reef sites representing an increasing gradient of annual mean diel temperature fluctuations of 1–3°C day-1. Bleaching severity and dark-acclimated photochemical yield (i.e., Fv/Fm) were quantified following exposure to five temperature treatments ranging from 23.0 to 36.3°C (see Related Datasets). This data set contains the comparison of thermal tolerance across studies.

Description

See the "Related Datasets" section for other closely related data that was also part of the study published in Brown et al., 2024.

Dataset "Short-term heat stress assay Heron Island - physiological data" contains a supplemental file ed50.csv which contains Photochemical yield and color score data from the Heron Island short term heat assay which was used to determine effective dose 50 (ED50, thermal tolerance). The Heron Island ED50 values are included in this thermal tolerance comparison dataset.

Methods & Sampling

Three published studies using the standardized experimental approach (i.e., (Evensen et al. 2023)) were identified to compare coral thermal thresholds across reef systems and spatial scales: 1. Florida Reef Tract in the Caribbean (~300 km) (Cunning et al. 2021), 2. Coral Sea in eastern Australia (~860 km) (Marzonie et al. 2022), and 3. Red Sea (~900 km) (Evensen et al. 2022). Reported values of coral thermal tolerance (i.e., Fv/Fm ED50) were compiled by nursery/reef/site. To compare regional (Florida Reef Tract, Coral Sea, Red Sea) coral thermal tolerance with local (Heron Island), the range of coral thermal tolerance was calculated for each species by computing the difference between the site with the greatest thermal tolerance and the site with the lowest thermal tolerance.
