This paper reports the physical and biological nest parameters of loggerhead turtle (Caretta caretta) nests on northern Cyprus that predispose individual nests to infestation. All data were collected between June and September 1997, and data were analyzed using generalized linear models. The final model explained 66.5% of the total deviance, and the most significant factor was the depth to the egg chamber (deviance = 63.86, P < 0.0001). The implications of these results are discussed, and recommendations for future work are proposed.
