Spatiotemporal Patterns In Orbicella Faveolata Wound Regeneration As An Indicator Of Colony Health, Alexander G. Wheeler

All HCAS Student Capstones, Theses, and Dissertations

Anthropogenic (e.g. damage from anchors, scuba divers, tissue sampling) and natural disturbances (e.g. predation, storm damage) can result in wounding of live tissue on coral colonies. Wounding has been shown to detract from a common resource pool, increasing disease susceptibility and impairing coral growth and reproductive activity. Regeneration not only varies between species, but also between conspecifics in the same location. A colony’s capacity to regenerate tissue can be an indicator of a colony’s condition and resilience. Understanding the physiological and environmental factors that affect tissue regeneration alongside the ultimate impact of sampling (disease and predation correlations) are needed for …
