Sex determination, sex ratios, and genetic conflict
Article Abstract:
Genetic conflict has a role in the driving diversity and turnover in sex determination in evolution. Genetic means of sex determination are surprisingly diverse and change during evolution at an unexpectedly fast rate. Genetic conflict is found where different components of a genetic system are affected by selection in opposite directions. Sex-determining mechanisms can be explained by genetic conflict theory as can cytoplasmic sex-ratio distortion, sex chromosome drive and cytoplasmic male sterility, which occurs in plants. Evidence that genetic conflict is important in evolution of sex-determining mechanisms is increasing.

Ecology, conservation, and public policy
Article Abstract:
Relationships of ecology, conservation, and public policy are discussed. Science in support of policy-making cannot be removed from values issues and equity questions. The role of specialists diminishes because no one can be an expert in all the aspects of all the things that must be considered. Disciplinary boundaries that once were useful are less so. Ecologists of the future must work with those in many other disciplines and training must involve core skills in those areas. A transformation is underway in ecology and related disciplines with influence in environmental issues, and a sense of urgency has arisen.

Quasireplication and the contract of error: lessons from sex ratios, heritabilities and fluctuating asymmetry
Article Abstract:
An analysis is presented on the contract of error arising from quasireplication, or the use of previous study formats for different systems or species. The author argues that incentives are needed to encourage formal replicative studies to ascertain the true magnitude of phenomena; these incentives include changes to research publishing policy and research funding priorities.
