Methods: 

Mark-multiple-recapture during four nights census of four 20 X 20 m plots. Frogs were located visually between 2000 to 2400 h using headlamps. Adults (greater than or equal to 25 mm) were captured and measured to 0.5 mm with dial calipers. Each was permanently marked by clipping a unique combination of toes. Sex and reproduction condition were noted. Detailed information on methodology can be found in Woolbright 2005 Herpetological Review 36:139-142.
