Both summer and winter survival of the fry in the experimental lakes varied according to genotype (Fig. 3).
Thus having tested for inbreeding depression in first year survival, we subsequently ran models for summer and winter survival to assess which period was driving any effect.
This was driven by effects on first winter survival rather than summer survival.
Rhizome quality (i.e., mass, length, diameter, viable buds, score), emergence, growth, and winter survival were measured on rhizomes planted in 2013 at Columbia and 2014 at Centralia, Missouri on clay loam soils with a range of DTC.
High variance in model estimates was caused by annual variability in adult female winter survival, adult female productivity, and fawn female summer survival.
They've evolved a strategy for winter survival that is unique, one that relies heavily on frenzied visitation to flowers throughout the summer and a Herculean group effort in the months beyond.
Decomposing first year survival into summer and winter survival indicated that the effect of offspring inbreeding coefficient on first year survival is driven by its effect on winter survival (coefficient=-15.2 ± 3.43, χ1 = 19.6, p < 0.001, table 3).
