Therefore, vaccination coverage may have contributed to the increase in diversity during period 3.
We found a high degree of diversity in period 3 (1970s and 1980s), with a DI of 94%, that was consistent with findings (84%) for a similar period in the United Kingdom (7 ).
These numbers reflect a tendency of decreasing genetic diversity from period 1 to 3, i.e., a change from a more even distribution of isolates among the detected MTs toward single dominant types.
Previous studies have suggested that a single SA strain often colonizes the nose for long periods of time in persistent carriers while strains colonizing intermittent carriers tend to exhibit more genotypic diversity as periods of decolonization and recolonization occur [ 9, 37].
The diversity of periods among the individual fibroblasts from which these lines are derived may also cause the difference in periods [ 18, 19]-.
Nitrate loss from drainage tiles across the cornbelt of the upper midwestern US is a result of intensive agriculture with limited crop diversity, extensive periods of fallow soil, and the need for high fertilizer applications to corn, all located on a hydrologically modified landscape.
Similarly, maintenance of diversity through periods of population supplementation has been demonstrated in both Chinook and Chum salmon (Eldridge and Killebrew 2008; Small et al. 2009).
The differences between Browning and Tennyson underline the creative diversity of the period.
Mr. Evans and others said the department seemed to have both improved its reputation and successfully combated crime during the period diversity took hold.
He's become the model of diversity in this period, and what's interesting about his campaign is that it has not sought to invoke engagements with race other than those that have already existed".
The species equitability (evenness) was relatively high during the rainy season indicating a reduction in the plankton diversity at this period (Adesalu & Nwankwo, 2008).
