Low field metabolic rates for geckos of the genus Rhoptropus may not be surprising

摘要: Abstract Geckos of the genus Rhoptropus are small diurnal lizards occurring in arid regions Namibia and Angola, not well studied relative to other desert lizards. afer has a field metabolic rate significantly lower than that lizards, but comparable studies have been carried out any species. We examined rate, water turnover, foraging behavior, thermal biology Bradfield's Namib day gecko, bradfieldi , Desert. This species occupies rocky habitats feeds on arthropods via sit-and-wait strategy. found it (140 J d −1 ) is 26% typical lizard same size (540 J d ). also R. bradfieldi had relatively high influx (0.07 ml d for its low energy suggest significant proportion this was sourced from fog. Active body temperatures varied between summer (32.7 ± 2.4 °C) autumn (34.4 ± 2.5 °C), both seasons maintained stable while active. Our study supports idea minimal requirement could be widespread within geckos.
