When selection favors sexual dimorphism, high-fitness parents often produce low-fitness progeny of the opposite sex. This sexual conflict is thought to overwhelm the genetic benefits of mate choice because preferred males incur a cost through the production of low-fitness daughters. We provide a counterpoint in a lizard (Anolis sagrei) that exhibits sexual conflict over body size. By using mate...

One patient was dropped from the study because of recurrent thrombosis of vascular access sites. In the other 13 patients, followed up for a mean of 9.1 months (range 8-11), haemoglobin concentrations increased from 62 (SD...

We also evaluate various policy alternatives designed ...
