Having equal length day and night shifts will make it administratively easier to achieve.
Specifically, PC1 and PC2 were expected to be correlated with vole reproduction because they summarize the seasonality of environment (food, day length, day length trend, temperature) and those factors are known to influence reproduction in mammals [ 2, 63].
For exposure to O3, Arabidopsis thaliana Col-0 or mutant plants were grown in a peat/vermiculite (1 1) mixture for 21 days in Weiss 1300 growth cabinets (photon flux density 250 μmol m-2 sec-1; tubular fluorescent lamps) under 12 hours day length (day: 23°C 70% relative humidity; night 18°C90%% relative humidity).
Estimates of broad sense heritability (H) for night sleep, day sleep, night bout number, day bout number, night average bout length, day average bout length, and waking activity, were, respectively H = 0.54, H = 0.49, H = 0.42, H = 0.33, H = 0.38, H = 0.19 and H = 0.39 (Additional file 1).
We previously profiled gene expression in six anther stages starting at day 5 (1.0 mm anther length), day 8 (1.5 mm, start of prophase I of meiosis), day 9 (2.0 mm, pachytene), day 15 (2.5 mm, tetrad), day 20 (3.0 mm, uninucleate gametophyte), day 30 (4.0 mm, binucleate gametophyte), and day 33 (mature, tricellular pollen) (Ma et al. 2008).
We chose it to test it based on the night sleep CV E and waking activity CV E GWAS results, yet significant pleiotropic effects were observed in day and night bout number, day and night sleep, day and night average bout length, day and night bout number CV E, and day and night average bout length CV E (Additional file 17).
Mr. Buffett spoke at greater length Sunday about more traditional topics of discussion for Berkshire meetings.
He was courted at length Monday by Donnie Walsh, the team president, and Coach Mike D'Antoni, and apparently left town feeling intrigued.
It was Dr. Benjamin's willingness to sacrifice — something health care reform may ask of many more doctors — that Mr. Obama discussed at length Monday.
Feinstein, who is from the Bay Area, spoke at length Tuesday about the value of the California desert.
He took flak for that in last week's debate, and former Massachusetts Gov. Mitt Romney argued at length Thursday as to why the policy "makes no sense".
