Discussion
- mod_3: temperature effects updated
- Observed incubation time is possibly long because of the coupling between reproduction and moulting
- Males are assumed to differ from females by {p_Am} only
- mod_4: males have equal state variables at b, compared to females
Facts
- A. aquaticus is a common species, living in natural surface waters (Ref: Wiki)
- It can eat many different types of food with a huge difference in growth (Ref: Wiki)
- Growth and reproduction are temperature dependent, in colder regions typically one brood/year is found, but in warmer climates this can increase up to four broods/year. (Ref: Wiki)
