In the August 2012 issue of Conservation Biology (volume 26, number 4) in “Population Dynamics of Hawaiian Seabird Colonies Vulnerable to Sea-Level Rise” by Hatfield et al. (pp. 667–678), Table 1 mistakenly contains 5 preliminary numbers rather than corrected area calculations. For the lidar DEM 2010 model, loss of land values for Tern Island for a 1.5- and 2.0-m rise in sea level should be 9.4% and 13.0%, respectively, and the loss of land value for Gin Island for a 1.0-m rise in sea level should be 47.1%. For the PhotoSat DEM 2011 model, loss of land values for Little Gin Island for a 0.5- and 1.5-m rise in sea level should be 6.2% and 87.5%, respectively. On page 673 in the second sentence of the first full paragraph in column one, 29.5% should be 25.3% and 72.7% should be 63.9%.
