The position of each frog was recorded on a pocket computer (MobileMapper 10, Spectra-Precision) in ArcPAD (ESRI) using a detailed background map (see the electronic supplementary materials for the full tracking procedure).
Male frogs were recorded squeezing inside hollow bamboo through small slits, where they attracted females with their calls.
Furthermore, riparian frogs with aquatic reproduction were recorded only in pastures.
Fast-conducting compound action potentials (CAPs) were recorded from frog sciatic nerve fibers by using the air-gap method.
Predation on adult frogs has been recorded for the red-bellied black snake, tiger snake, laughing kookaburra, and sacred kingfisher; wading birds and other snakes, such as the green tree snake and the copperhead snake, are also believed to be predators of the frog.
More species of frogs and toads have been recorded than are native to the US and Canada combined; more birds than in all of Europe.
Captive frogs and toads have been recorded as living for up to 40 years, an age achieved by a European common toad (Bufo bufo).
Adult tree frogs, for instance, have been recorded to lose, through evaporative passive water flux, up to 250 mL body water/kg/day, far exceeding the less than 3 mL/kg/day loss of most reptiles (Shoemaker and Nagy 1977).
Scarabaeid beetle larvae, oribatid and mesostigmatid mites and occasionally microhylid frogs were also recorded in the diet.
The frogs were positioned for recording on a small piece of stiff foam, and placed on a vibration-isolated table (Newport, Model VH3048W-OPT) inside an anechoic sound isolation chamber (Industrial Acoustics Company, Inc .. Acoustic stimuli were delivered by BrainWare [Tucker Davis Technologies (TDT)] at 200 kHz sampling rate (TDT RP2.1).
