This paper reports the physical nest parameters of loggerhead turtle (Caretta caretta) nests at Fethiye Beach, Turkey that predispose individual nests to invertebrate infestation. All data were collected between June and September 2001 and were analyzed using logistic regression. Pimelia sp. (Tene-brionidae), Musca sp. (Muscidae), Myrmeleon sp. (Myrmeleontidae), and Cryptositigmata were established as infesting the loggerhead turtle nests on Fethiye Beach in 2001. When all groups were combined as invertebrates, distance to low vegetation (t-test, b = -0.13) and grain size (t-test, b = -1.30) were found to be the best subsets of the model indicating whether invertebrates infested a nest. Both factors were negatively correlated with the presence of invertebrates. The same analysis was applied for each individual group of invertebrates. The implications of these results are discussed.
