  1. Amphibians: Provide particular enclosure furniture for calling sites, breeding areas or egg laying sites

    A before-and-after study in 2010-2012 in Vienna, Austria found that captive Staurois parvus and Staurois guttatus started breeding when animals were housed in terraria with more calling, perching and laying sites, and with simulated wet and dry seasons, although no statistical tests were carried out. Neither species bred successfully in captivity before 2011. Once animals were moved to breeding arenas with a more complex habitat in August 2011, S. parvis tadpoles were observed from October 2011 and S. guttatus tadpoles from March 2012. By 2012, a total of 285 S. parvis froglets, 600 tadpoles and 180 juveniles had been raised and 76 S. guttatus tadpoles had been raised. In August 2011, five pairs of each species were moved from a medium-sized (50 × 60 × 70 cm) terraria with tree branches, plants and stones and no simulated wet and dry seasons, to larger (150 × 120 × 100 cm) enclosures with controllable waterfalls, plants, small burrows, ledges for calling sites and perching sites, and simulated wet and dry seasons. The waterfall for S. guttatus also had several tree branches.

  2. Amphibians: Vary artificial rainfall to simulate seasonal changes in the wild

    A before-and-after study in 2010-2012 in Vienna, Austria found that captive Staurois parvus and Staurois guttatus started breeding when wet and dry seasons were simulated, and frogs were moved to a larger enclosure with more calling, perching and laying sites, although no statistical tests were carried out. Neither species had bred successfully in captivity before 2011. Once the animals were moved to two breeding enclosures with simulated wet and dry seasons and with more calling perching and laying sites in August 2011, S. parvis tadpoles were observed from October 2011 and S. guttatus tadpoles from March 2012.  By 2012, a total of 285 S. parvis froglets, 600 tadpoles and 180 juveniles had been raised and 76 S. guttatus tadpoles had been raised. In August 2011, five pairs of each species were moved from a medium-sized (50 × 60 × 70 cm) terraria with tree branches, plants and stones and no simulated wet and dry seasons, to two larger (150 × 120 × 100 cm) enclosures with controllable waterfalls, plants, small burrows, ledges for calling sites and perching sites. The waterfall for S. guttatus also had several tree branches. Each enclosure had a simulated 14 day dry period, followed by a 14 day simulated rainy season (4 hours daily rainfall) with the temperature in both enclosures at 22-27°C.
