2name:Reproduction of benthic foraminifera
3info:~
4Basic information about this simulation:
5www.framsticks.com/foraminifera
6
7Technical information:
8Genes and parameter values which control reproduction are stored in data->genes and data->lifeparams fields.
9
10genes:
11genes which are not encoded in Ff genotype:
12min_repro_energy - Minimum energy necessary for reproduction
13hibernation - Defines foram behavior in the case of no nutrients
14
15lifeparams:
16Physiological parameters of foraminifera:
17max_energy_level - maximum energy level reached so far
18gen - generation: 0 haploid, 1 diploid
19species - species: 0 not hibernating 1 hibernating
20hibernated - 0/1 foram is/isn't hibernated
21reproduce - 0/1 foram isn't/is ready for reproduction
