This shows the potential impact of breeding for stress tolerance.
This approach, many of her associates said, had the effect of breeding resentment at campaign headquarters.
As a first step, we look for effects of breeding experience on breeding date and clutch size when controlling for female age, to see whether our coding of experience is meaningful.
Here, we investigated the effects of breeding design and water temperature for offspring on fertilization, hatchability, larval survival, size, abnormality and metamorphosis of the sea urchin Strongylocentrotus intermedius, whose dams and sires were exposed to long-term (~15 months) elevated temperature (~3 °C above ambient) or ambient temperature.
To test for effects of breeding treatment on male and female weight, we recorded the mass of third-generation offspring 10 days after birth and then at 10-day intervals until the offspring were 60 days old.
Overall, we conclude that this approach could become an important tool to the study of dispersal and more general for investigating effects of breeding environment on behaviour and reproductive success.
Adjustment of the indices and indicator to allow for possible effects of breeding habitat, migratory behaviour and mean body mass only alters this pattern very slightly (Text S2, Figure S2, Table S11), so it is not spuriously driven by the other potential sources of environmental change that we examined.
We tested for the fixed effects of breeding mode and salt environment on fertility with GLMMs by taking block as the random independent variable.
In contrast, the estimate of rg of uniformity of BW between BE and PE was close to 0 (-0.08 ± 0.33), which indicates that, after accounting for the scale effect, the ranking of breeding values for uniformity of BW between BE and PE was independent.> -wrap-foot> BE = breeding environment; PE = production environment.
