### Readme file for Dryad data Title: Janzen-Connell effects partially supported in reef-building corals: adult presence interacts with settler density to limit establishment Authors: Carrie A. Sims, Eugenia M. Sampayo, Margaret M. Mayfield, Timothy L. Staples, Steven J. Dalton, Nataly Gutierrez-Isaza, and John M. Pandolfi. Corresponding email: carrie.sims@uqconnect.edu.au ------------------------------------------------------------------------------------------------------------------- Data File: Simsetal2021_JCEffectsCorals_Heron2017-settle-survive.csv. #----------------------- Data contains the number (count) of successful settlers at settlement and settled survivors at post-settlement survival for each replicate settlement tile per treatment combination (species/density/adult). Data was collected from experimental arenas (containers with settlement tile) and conducted at Heron Island research station situated on the southern Great Barrier Reef during the November 2017 coral spawning season. #----------------------- Dataset contains: - 180 observations (rows) + 1 row (header) - 10 variables (columns) #----------------------- Variables Format Description Tile ID numeric Unique number for each replicate settlement tile Density categorical Number of larvae in treatment Trait categorical Coral colony growth form Life History categorical Life history strategy characterisation of coral species (as per Darling et al. 2012) Genus categorical Genus of coral species Species categorical Coral species scientific name Adult categorical Adult water treatment used, absent (no adult) versus present (conspecific adult) Rep Tile numeric Replicate tile number # Settled numeric Number of larvae successfully settled on settlement tile, taken as count per tile # Survived numeric Number of settlers that survived till post-settlement survival stage on settlement tile, taken as count per tile ------------------------------------------------------------------------------------------------------------------- Data File: Simsetal2021_JCEffectsCorals_Heron2017-diversity.csv. #----------------------- Data contains the number (count) of successful settlers at settlement for each replicate settlement tile per treatment combination (species/species frequency or species/species mix). Data was collected from experimental arenas (containers with settlement tile) and conducted at Heron Island research station situated on the southern Great Barrier Reef during the November 2017 coral spawning season. #----------------------- Dataset contains: - 78 observations (rows) + 1 row (header) - 8 variables (columns) #----------------------- Variables Format Description Tile ID numeric Unique number for each replicate settlement tile Species Mix categorical Indication of the coral species mixed in a treatment (initials of coral species name) Species ID numeric Unique number for each coral species Species Frequency categorical Species diversity level for each treatment Density categorical Number of larvae in treatment Genus categorical Genus of coral species Species categorical Coral species scientific name # Settled numeric Number of larvae successfully settled on settlement tile, taken as count per tile for each species
