Figure 2
Life-history traits of the three strategies (a–c). Number of zooids in up to 17 data-collection sessions during the life spans of each of the 81 Botryllus colonies studied. The colonies are grouped into the three life-history strategies: (a) NF; (b) FA; (c) FB. The dashed vertical lines in (b) and (c) depict average ages for the first fission. (d–f) A typified representative of each of the three life-history strategies. (d) Colony NF29 as an example of the non-fission (NF) strategy. (e) Colony FA5 as an example for fission after zooids reach peak size (FA). (f) Colony FB9 as an example of fission before zooids reach peak size (FB). Life-history traits presented: the numbers of zooids (green curve), RS scores (red curve) and CV scores (black curve). Vertical black lines outline RS segments (RSS), with the length (days) marked for each RS segment. Vertical dotted orange lines depict fission events.
