Foundation species such as redwoods, seagrasses and corals are often long-lived and clonal. Genets may consist of hundreds of members (ramets) and originated hundreds to thousands of years ago. As climate change and other stressors exert selection pressure on species, the demography of populations changes. Yet, because size does not indicate age in clonal organisms, demographic models are missing data necessary to predict the resilience of many foundation species. Here, we correlate somatic mutations with genet age of corals and provide the first, preliminary estimates of genet age in a colonial animal. We observed somatic mutations at five microsatellite loci in rangewide samples of the endangered coral, Acropora palmata (n = 3352). Colonies harboured 342 unique mutations in 147 genets. Genet age ranged from 30 to 838 years assuming a mutation rate of 1.195−04 per locus per year based on colony growth rates and 236 to 6500 years assuming a mutation rate of 1.542−05 per locus per year based on sea level ... : DuranteEtAl_Apalmta_Genotypes_n=3352Genotypes for the coral, Acropora palmata from five microsatellite loci. A. palmata is a diploid species, however, somatic mutations in the form of third and fourth alleles per locus are occasionally detected. Samples are in rows (n = 3352), genotypes are in columns. Table Headers Species: Acropora palmata Region: Caribbean and North-west Atlantic. Database ID: A unique name given to each coral sample. Locus 166, alleles 1-4: Locus 166 is a microsatellite locus. Alleles are given in basepairs. Locus 181, alleles 1-3: Locus 181 is a microsatellite locus. Alleles are given in basepairs. Locus 182, alleles 1-4: Locus 182 is a microsatellite locus. Alleles are given in basepairs. Locus 192, alleles 1-4: Locus 192 is a microsatellite locus. Alleles are given in basepairs. Locus 207, alleles 1-3: Locus 207 is a microsatellite locus. Alleles are given in basepairs. Genet ID: All samples that share all ancestral alleles at five microsatellite loci were assigned the same genet ID. ...
