Maintenance of clonal diversity in Dipsa bifurcata (Fallen, 1810) (Diptera: Lonchopteridae)

Article Abstract:

The deterministic maintenance of clonal diversity in thelytokous taxa can be seen as a model for understanding how environmental heterogeneity both can stabilize genetic diversity and can allow for coexistence of competing species. It is concluded that in general, fluctuating seasonal fitness can maintain stable genetic polymorphism within populations, as well as coexistence between closely related competitors when coupled with differences in dispause phenology.

Genetic diversity and differentiation in Eryngium alpinum L. (apiaceae): comparison of AFLP and microsatellite markers

Article Abstract:

A study is conducted to investigate genetic diversity and structure of 13 populations of Eryngium alpinum L. with the help of 63 dominant amplified fragment length polymorphism (AFLP) and seven codominant microsatellite markers. The findings indicate that genetic patterns are more congruent with the spatial arrangement of populations when inferred from microsatellitees than from AFLP.

Maintenance of clonal diversity in Dipsa bifurcata (Fallen, 1810) (Diptera: Lonchopteridae)

Article Abstract:

An analysis is done of a selection model analogous to a one-locus, two-allele haploid system than can explain recurrent seasonal changes in diversity for communities with diapausing species or populations with diapausing clones. In general clones or species that share the same spatial habitat can persist in stable coexistence even if there are differences in their dormancy patterns.
