The effects of a chromosomal inversion on adult size and male mating success in the seaweed fly, Coelopa frigida

SummaryAn association is reported between the α/β inversion polymorphism on chromosome I and adult size as assessed by the length of wings, αα flies are larger than ββ flies, with heterokaryotypes…
Properties of genetically polymorphic isozymes of alcohol dehydrogenase in Drosophila melanogaster

Studies of the isozymes produced by alternative alleles at the alcohol dehydrogenase locus of Drosophila melanogaster indicate that the ADH F enzyme is more active but less stable than the ADHS…
Female mating preference for large size in Coelopa frigida (seaweed fly)

It is suggested that the discrepancy between the mean size of males in natural populations and the preferred male size indicates that the forces of natural (viability) selection and sexual selection act in opposition.
Adult size, longevity and fecundity in the seaweed fly, Coelopa frigida
An inversion polymorphism of chromosome I in the seaweed fly, Coelopa frigida, is known to affect adult size and components of fitness and the longevity of males and females, female fecundity and the number of matings achieved by males have been measured using laboratory lines.

Genetic variation at the alcohol dehydrogenase locus in natural populations of the seaweed fly, Coelopa frigida

It is argued that the remarkable geographical uniformity of the seaweed fly must indicate the presence of strong selection, probably taking the form of heterokaryotypic advantage.
A chromosomal inversion polymorphism in Scandinavian populations of the seaweed fly, Coelopa frigida.

It is suggested that heterokaryotypic advantage is the major selective force maintaining this polymorphism, and that genotype-related differences in generation times, and the longevity of seaweed beds, may constitute lesser forces acting on the inversion frequencies.
Coexistence of competing species of seaweed flies: the role of temperature

- 1 February 1995
The larval distributions are shown to be caused primarily by the behaviour of the larvae themselves ‐ not by choices made by ovipositing females, nor (at least to any great extent) by differential survival.
Mating behavior in seaweed flies (Coelopa frigida)
- T. Day, S. Foster, G. Engelhard
- BiologyJournal of insect behavior
- 2005
The observed opportunities for female choice, male choice, and male-male competition are discussed in the light of previous reports of differential male mating success and of assortative mating with respect to size and genotypes.
