How far do adult turtles move? Home range and dispersal of Kinosternon integrum

We describe the home range and movements of a population of Kinosternon integrum in Tonatico, Estado de Mexico, Mexico, over 3.5years (during rainy and dry season months) using radiotelemetry in 37 adult turtles. The results showed that the home range of K.integrum was 0.151 +/- 0.051ha using 50% kernel density estimator (KDE), and 0.657 +/- 0.214ha using 95% KDE; the home range did not vary between sexes. Kinosternon integrum showed low distances traveled 51.44 +/- 4.50m, where 87.3% (n=373) of movements were <100m. The distance traveled differed by season, and movement category (aquatic and terrestrial movements). The shortest distance occurred during the dry season, during which some individuals move to estivation sites, and these movements were shorter than movements to artificial ponds (cattle ponds). In this population, home range and movement are similar to other species of the genus Kinosternon. Overall, the results indicate than K.integrum are highly dependent on aquatic habitats, but also utilize the terrestrial habitats for different biological activities, and to maintain viable populations. Therefore, the conservation of the entire inhabited area is fundamental. This study highlights the need to increase the studies, in Central Mexico, concerning habitat use of freshwater turtles in order to increase the efficiency of conservation strategies.
