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)
