We sought to investigate the role of genetic, intra-clonal, and environmental variation in driving variation in fitness-related traits in the Caribbean thin finger coral, Porites divaricata (Taxonomy ID: 262287). We conducted a reciprocal transplant experiment whereby fragments from individual coral colonies of known genetic background were transplanted to three sites from February to July 2022. These sites included two mangrove sites and one reef site at Calabash Caye, Turneffe Atoll, Belize. P...

Reciprocal transplant experiment:
In February 2022, 32 colonies (subclone/ramet) of the Caribbean thin finger coral, Porites divaricata (Taxonomy ID: 262287) were identified. 3 to 9 branch fragments were collected from every subclone (colony/ramet). 1 to 3 fragments from each ramet were moved to three designated sites: M1 (mangrove site 1), M2 (mangrove site 2), and R (reef site). 7 to 9 adjacent ropes were deployed at each site (seven ropes at M1 and R, and nine ropes at M2). Following a six-month period (February 2022 - July 2022), two traits were measured for each fragment: length change and red channel intensity, which serves as an inverse indicator of chlorophyll pigment density (Winters, Holzman, Blekhman, Beer, & Loya, 2009).

Environmental Measurements:
Four Onset HOBO Pendant data loggers (Onset Corporation, Bourne, MA) were deployed at the time of transplant to record both temperature (°C) and light intensity (lux) every two hours and remained there over the duration of the experiment. Lux was converted to photosynthetic photon flux density (PPFD: micromoles per square meter per second (µmol m-2 s-1)) with a standard sunlight conversion factor of 0.018.
