IRS1 - An Unequivocable Comfort!

The mean log10 area of the diatom valves from the community is statistically indistinguishable across most of the depths analyzed with the exception of the surface sediments (?last 50 years) when the log10 mean area becomes significantly smaller (Table 1 and Fig. 3). There is no significant linear relationship between the mean area of the diatom valves in the community (log A) or proportion of small centrics in the community and local spring-summer temperatures over the last two centuries (linear regression, p > 0.05). Table 1 Significance tests on the change in the mean size of valves in the diatom community and specified sub-populations over time. Figure 3 Change in the size and taxonomic structure of the diatom community and selected sub-populations over the last ?200 years. Changes in mean size and relative percent abundance and of the dominant taxa over time The average area of the small centric diatoms Selleckchem Rapamycin (2 SE) ?m2, and does not vary significantly with time/depth (Table 1). The average area of Aulacoseira valves range from 96.6 to 109.6 ?m2, and in volume from 1,436 to 1,723 ?m3, depending on the species and variety. In contrast with the small centric species, JQ1 cell line the average valve sizes (A, AM, SA, and V) of Aulacoseira lirata var. biseriata, A. lirata var. lirata, A. perglabra var. floriniae but not A. perglabra var. perglabra does change significantly with depth/time (Table 1); increasing in A, SA, and V since ?1800 AD (Fig. 4). There are small, but significant, changes in the aspect ratio of Aulacoseira with depth (ANOVA, p IRS1 with a decrease in the relative abundance of Aulacoseira species over time (Fig. 3).
