Morph frequencies, sex ratios and infections in <i>Danaus chrysippus</i> populations in Rwanda
نویسندگان
چکیده
The African Queen butterfly (Danaus chrysippus) is noted for its colour pattern polymorphism despite aposematic and chemically defended lifestyle infection with a male-killing endosymbiont (Spiroplasma). largely restricted to east central Africa where three different forms meet interbreed in large contact or hybrid zone. primary objective of this study present recent data on the polymorphism, sex ratio incidence male killing D. chrysippus populations Rwanda. We also report previously unpublished from random sample collected 1914 Bujumbura Burundi differential effects weather males females Ghana 1972 1974. sampled butterflies using nets either marked, recorded released them kept specimens subsequent examination. used PCR/microscopy preserved detect Spiroplasma presence protozoan parasite (Ophryocystis). Our findings suggest that Rwanda lies close western edge joint distribution both polymorphism. Further biogeographical studies are recommended test hypothesis zone which commonly observed.

Optimal sex ratios in structured populations.
In this paper, we develop a general method to determine evolutionary equilibrium sex ratios and to check evolutionary stability, continuous stability and invadability in exact genetic models with or without dominance. This method is then applied to three kinds of models for structured populations: the first one concerns Hamilton's LMC model, except that only a fraction beta of female offspring ...
متن کاملAbnormal sex ratios in human populations: causes and consequences.
In the absence of manipulation, both the sex ratio at birth and the population sex ratio are remarkably constant in human populations. Small alterations do occur naturally; for example, a small excess of male births has been reported to occur during and after war. The tradition of son preference, however, has distorted these natural sex ratios in large parts of Asia and North Africa. This son p...
متن کاملEcological genetics of sex ratios in plant populations.
In many angiosperm species, populations are reproductively subdivided into distinct sexual morphs including females, males and hermaphrodites. Sexual polymorphism is maintained by frequency-dependent selection, leading to predictable sex ratios at equilibrium. Charles Darwin devoted much of his book 'The Different Forms of Flowers on Plants of the Same Species' (1877) to investigating plant sex...
متن کاملBayesian reconstruction of two‐sex populations by age: estimating sex ratios at birth and sex ratios of mortality
The original version of Bayesian reconstruction, a method for estimating age-specific fertility, mortality, migration and population counts of the recent past with uncertainty, produced estimates for female-only populations. Here we show how two-sex populations can be similarly reconstructed and probabilistic estimates of various sex ratio quantities obtained. We demonstrate the method by recon...
