From: Haploid females in the isomorphic biphasic life-cycle of Gracilaria chilensis excel in survival

Allee effects over thesurvival (φ) of G. chilensis individuals with fronds. Each panel (a, b and c) corresponds to a range of algal stand density (V). The φ is shown in the left y-axis and its corresponding finite survival rate (s) in the right y-axis. Individuals were grouped according to their ages as < 8 month (young) or > 8 month (old). Frond volume (v) given in cm3, according to their stage as males (M), females (F) or diploids (D), and according to their pool as Corral 1 (C1), Corral 2 (C2), Niebla 1(N1), Niebla 2 (N2) and Niebla 3 (N3). The line-fits with poor non-linear correlation coefficients (R2 < 0.5) were replaced by their group mean
