“…The novel incorporation of a transparent 3-L urine bag into the “Flexi-Chamber” design led to an easily managed, low-cost device for use by any underwater scientists, where short incubations are able to detect changes in biological processes absent of any visual signs of coral stress or change in endosymbionts concentration ( Camp et al, 2015 ). A similar benthic chamber design was used to show that abiotic conditions, including light intensity, were drivers of spatial-temporal patterns of reef metabolism, although some limitations on the use of these incubation chambers emerged when applied on large boulder colonies ( Pramneechote et al, 2020 ). Here, the amount of light available for photosynthesis and the energetic budget can vary based on colony shape (micro niches) and the immediate surrounding environment (backscattering light; Wangpraseurt et al, 2014 ).…”

Coral reefs are declining worldwide due to global changes in the marine environment. The increasing frequency of massive bleaching events in the tropics is highlighting the need to better understand the stages of coral physiological responses to extreme conditions. Moreover, like many other coastal regions, coral reef ecosystems are facing additional localized anthropogenic stressors such as nutrient loading, increased turbidity, and coastal development. Different strategies have been developed to measure the health status of a damaged reef, ranging from the resolution of individual polyps to the entire coral community, but techniques for measuring coral physiology in situ are not yet widely implemented. For instance, while there are many studies of the coral holobiont response in single or limited-number multiple stressor experiments, they provide only partial insights into metabolic performance under more complex and temporally and spatially variable natural conditions. Here, we discuss the current status of coral reefs and their global and local stressors in the context of experimental techniques that measure core processes in coral metabolism (respiration, photosynthesis, and biocalcification) in situ, and their role in indicating the health status of colonies and communities. We highlight the need to improve the capability of in situ studies in order to better understand the resilience and stress response of corals under multiple global and local scale stressors.

“…The design of a transparent 3-L urine bag as the "Flexi-Chamber" made it easily usable at lowcost by any underwater scientists, where short incubations detected changes in biological processes with no visual signs of coral stress or endosymbionts concentration [120]. A similar design was used as benthic chambers to show that abiotic conditions including light intensity were drivers of spatial-temporal patterns of reef metabolism [122], although some limitations on the use of these incubation chambers emerged when applied on large boulder colonies. For instance, the amount of light available for photosynthesis, and relative energetic budget, can have different role based on colony shape (micro niches) and surround environment (backscattering light) [123].…”

Coral reefs are declining worldwide due to global changes in the marine environment. The increasing frequency and severity of massive bleaching events in the tropics are highlighting the need to better understand the stages of coral physiological responses to extreme conditions. Moreover, like many other coastal regions, coral reef ecosystems are facing additional localized anthropogenic issues such as nutrient loading, increased turbidity, and coastal development. The changes in coral metabolism under local or global stress conditions is studied largely through laboratory manipulation and field observations. Different strategies have been developed to measure the health status of a damaged reef, ranging from the resolution of individual polyps to an entire coral community, but techniques for measuring coral physiology in situ are not yet widely implemented. For instance, while there are many studies of the coral holobiont response in single or limited-number multiple stressor experiments, they provide only partial insights to metabolic performance under more complex temporally and spatially variable natural conditions. Here, we discuss the current status of coral reefs and their global and local stressors in the context of current experimental techniques that measure core processes in coral metabolism (respiration, photosynthesis, and biocalcification) and their role in indicating the health status of colonies and communities. The state of the art of in situ techniques for experimental and monitoring purposes is explored. We highlight the need to improve the capability of in situ studies in order to better understand the resilience and stress response of corals under multiple global and local scale stressors.
