Thus, our endurance data are consistent with our hematological data, indicating that the results presented here are not simply an artifact of the method: our sampled toads from Cairns were in no way physiologically inferior to the toads sampled from the invasive front.
Although mitotic chromosomes are otherwise hard to image by high-resolution methods, our sample preparation for mitotic chromosomes using Drosophila syncytial blastoderm embryos eliminated massive cellular background, and enabled efficient sample flattening and rapid chemical fixation.
First, given that we recruited participants for the survey using online methods, our sample was limited to young people with Internet access.
Having employed qualitative methods, our sample is not necessarily representative, nor does it intend to be representative, of all UK trainers and trainees.
When applying the sibling FE method to our sample of married White women, we obtain results similar in size and significance to those obtained with OLS (comparing panels A and C Table 3).
The power to detect such an effect by our method, given our sample size, is greater than 87% for any value of α greater than 0.01.
As expected, hanging was found to be the most common suicide method in our sample, and suicide incidence was much higher for men (Table 3).
To judge the sensitivity of our rule-based method to reductions in sample size, we computed the relative amount of climate space that would have been detected by our method had our sample been a random subset of the original 149 localities [2].
Because we predicted a strong effect based on previous work (Cook et al. 2005) and because it was expensive to apply PhyloChip methods, our final sample size totaled 24 samples for phylochip analysis from 6 incubated and 6 unincubated eggs.
Furthermore, as explained in the methods section, our sample size was sufficient to simultaneously adjust for a good amount of possible confounders.
