Whether or not storm frequency has changed over time is not clear because of large natural variability from such climate drivers as the ENSO (IPCC 2007a).
The Hansen paper shows that these frequencies have changed substantially, both globally and throughout the Northern Hemisphere.
Stool frequency had changed in two patients, no patient experienced new urge-symptoms or fecal incontinence.
Participants who indicated that sexual frequency had changed, were asked to indicate what factors were perceived to be the cause of such change, using a yes/no response.
Frequencies of 0.05 or higher in the pre- or postunit survey were further analyzed to calculate the degree to which the word frequencies had changed pre- to postunit.
Results thus indicate that μsat allelic frequencies have changed from the past to the present.
This is due to the need to correct for kinship: on adjustment, loci tagging QTL whose frequencies have changed will have their power of detection reduced.
In future experiments, we will seek to identify the nature, genomic location and phenotypic effects of single nucleotide polymorphisms whose frequencies have changed under artificial selection in this unique mouse sample.
These findings were consistent with genetic characterizations of populations whose allele frequencies have changed because of some perturbation.
Furthermore, within the remaining individuals the frequency has not changed.
