Abstract

FRENKEL, Caty. Hemidactylus frenatus (Squamata: Gekkonidae): call frequency, movement and condition of tail in Costa Rica. Rev. biol. trop [online]. 2006, vol.54, n.4, pp.1125-1130. ISSN 0034-7744.

Call frequency and movements of the gecko Hemidactylus frenatus were studied in Punta Morales, Costa Rica from April 1999 through May 2000. Call activity of H. frenatus was positively related to air temperature at night and throughout the year. Higher activity was at dusk, dawn, and during the hottest months. Call frequency was related with gecko abundance per month, although not during the night. More males and females had a regenerated tail compared to juveniles, the last ones could have it complete or regenerated. Females moved longer distances than males and juveniles. Adults were found higher on walls. Males and females were recaptured more times than juveniles, and the period of time between their recaptures was longer. Members of this population do not seem to be as aggressive to other geckos as mentioned in the literature. Rev. Biol. Trop. 54 (4): 1125-1130. Epub 2006 Dec. 15
