Sexual isolation and cuticular hydrocarbons in Drosophila elegans

Article Abstract:

A study to understand how Drosophila elegans discriminates between potential mates has been carried out. Partial sexual isolation has developed between the brown and black morphs, but body coloration is not used as a sexual cue. Sexual isolation and cuticular hydrocarbons are discussed.

The role of fertility restoration in the maintenance of the inversion In(2L)t polymorphism in Drosophila melanogaster

Article Abstract:

The article concentrates on the extent of fertility restoration in Drosophila melanogaster after high temperature treatment that induces complete sterility of both females and males. Juvenile survival rates and genetic adaptations after heat stress are discussed.

Molecular population divergence and sexual selection on morphology in the banded demoiselle (Calopteryx splendens)

Article Abstract:

Molecular population divergence revealed by amplified fragment length polymorphism analysis was investigated. Observations suggested that molecular population divergence was highly significant among the Northern European populations.
