Discussion
- Metabolic acceleration is here linked to establisment of internal algal symbiont population
- Reproduction efficiency kap_R has been set to 0.95/2 because the species is simultaneous hermaphroditic
Facts
- Neonates have no symbionts. Juveniles only ingested the geen alga Platymonas convoluta (Volvocaceae) as symbiont; the algae take 2-3 d to increase amd migrate throught the body without thecae and in 15-20 d the animal is uniformly green (Ref: Doug1983)
- Food uptake by phagocytosis (Ref: Doug1983)
- host supplies symbionts with uric acid (Ref: Doug1983a)
