Asexual fitness
In males, asexual fitness was significantly affected by treatment (LRT,
Negative binomial GLMM with linear parametrization, λ2= 26.96, p < 0.001). The number of buds produced increased if
polyps were exposed to a simulated summer heat wave and if they were
cultured under elevated winter temperatures, or they received both
treatments compared to a cold summer-cold winter scenario (Table 1, Fig.
4A.). In females, by contrast, treatment had no effect on asexual
fitness (LRT, Negative binomial GLMM with quadratic parametrization,
λ2 = 6.11, p = 0.106).
