Discussion

  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3

Facts

  • grazes extensively upon mixed grasses and favors succulents and thistles (Ref: Wiki)
  • females often larger than males (Ref: ADW)
  • females develop from eggs incubated above 30 C, males below 30 C (Ref: ADW)
