| Abstract |
|
Caatinga has a semiarid climate with strong seasonality and long periods of drought, which should require adaptations in the species in the region. Hence, we studied how the freshwater turtle species Phrynops tuberosus, a very water dependent animal, deals with these adversities. The present study aimed to evaluate the influence of seasonality on nesting sites, hatching period and to report and discuss the use of secretive habitat by hatchlings for the freshwater turtle species P. tuberosus, from central hinterland of the state of Ceará. Data collection occurred in the Cedro water reservoir, located in Quixadá-CE, Brazil, between October 2011 and September 2012. We measured nests (n = 30) and hatchlings (n = 24) of the studied species. Nests were always found in shaded areas. Hatchlings were more abundant in the rainy season and showed cryptic behaviour. We observed that the life history traits of these animals were related to the rainy season in the region.
