Sexual size dimorphism and timing of spring migration in birds.
Sexually selected traits are limited by selection against those traits in other fitness components, such as survival. Thus, sexual selection favouring large size in males should be balanced by higher mortality of larger males. However, evidence from red-winged blackbirds (Agelaius phoeniceus) indicates that large males survive better than small males. A survival advantage to large size could re...

متن کاملAssessing the role of reproduction and stress in the spring emergence of haematozoan parasites in birds.
A spring emergence of avian haemosporidian infections is nearly universal among temperate zone birds and is often described as a cost of reproductive effort. We take advantage of the opportunistic (i.e. aseasonal) breeding schedule of the red crossbill (Loxia curvirostra) to determine the relative contributions of season versus host physiology to the timing and intensity of Haemoproteus infecti...
