Eye diameter and body length measures on lab-reared Daphnia obtusa for broad-sense heritability estimation

Eye diameter (um) and body length (um) measurements from a common garden experiment on a number of clones of Daphnia obtusa isolated from ponds in Congaree National Park, South Carolina. Each row corresponds to associated identifiers and measurements for a single individual Daphnia. Pond of origin indicates the name of the pond that the original clone was isolated from. D. obtusa clone refers to the name of the clone (pond abbreviation and a number for specific identity). Daphnia size class was determined as small (≤900 μm), medium (901 μm -1399 μm), and adult (≥1400 μm). These size classes reflect ontogenetic growth from juveniles to adults.
