    Notes: Summary Aedes albopictus is commonly distributed in most parts of the Oriental region and on many islands in the Indian and the Pacific Oceans. The species was recently introduced into the United States and Brazil. Feulgen cytophotometric quantitation of haploid nuclear DNA content was carried out for 37 populations of Ae. albopictus to determine the extent of intraspecific variation in nuclear DNA content and whether the range expansion of the species has coincided with an increase in DNA content. The haploid nuclear DNA content varied nearly three-fold. The minimum DNA content was 0.62 pg in Koh Samui from Thailand, and the maximum DNA content was 1.66 pg in Houston-61 from the United States. Statistical comparisons of populations revealed significant differences in DNA contents. No geographic clustering of populations was noted with respect to DNA content. In general, populations from the United States and Brazil had higher DNA contents, but there was no indication that the range expansion had occurred hand in hand with an increase in DNA content. Each population had a specific amount of DNA that is probably imposed by the microenvironment.

    Correlations between 2C DNA values and habit inCassia (Leguminosae:Caesalpinioideae) (1986)

    Notes: Abstract Ten species of the genusCassia show a range of 2C DNA amounts from 1.30 to 2.54 pg at the same ploidy level. Remarkably, a distinct 2-fold increase is depicted by an arboreal speciesC. excelsa while the rest comprising of herbs, trees and shrubs have a range from 1.30 to 1.47 pg. These form a natural grouping with respect to mean DNA amounts which differ by 0.05 pg in the herbs, trees and shrubs respectively.
