Do migratory birds and mammals have faster paces of life?

After controlling for latitudinal and evolutionary patterns, we find that migratory birds and mammals have faster paces of life than their non-migratory relatives. Among swimming and walking species, migrants tend to have larger body size, while among flying species, migrants are smaller. ...

Does flight mode affect allometry of migration range in birds?

Watanabe, Y. Y. Flight mode affects allometry of migration range in birds. Ecol. Lett. 19, 907–914 (2016). Newton, I. The migration ecology of birds. (Academic Press: Oxford, 2008). Speakman, J. R. & Król, E. Maximal heat dissipation capacity and hyperthermia risk: neglected key factors in the ecology of endotherms. J. Anim. ...

Does migratory behaviour affect vertebrate life histories?

Here we provide a global analysis of associations between migratory behaviour and vertebrate life histories. After controlling for latitudinal and evolutionary patterns, we find that migratory birds and mammals have faster paces of life than their non-migratory relatives. ...

Does biogeography drive the evolution of migratory behaviour?

A first set of hypotheses emphasise the role of ecology and biogeography in driving the evolution of migration. Based on standard life history theory 16, 17, these assume that the external context of the organism drives the evolutionary optimisation of traits that shape migratory behaviour via natural selection 8. ...

Do migratory birds live longer?

Yet the patterns across studies are inconsistent, with some studies reporting reduced lifespan in migratory birds, owing to elevated (direct) mortality during migration 23, 24, 25, and others suggesting high rates of survival throughout the annual cycle, including during migration 26. ...

Does migration have costs in terms of survival?

Predictions are difficult to generate given the contradictory evidence base, but we propose that when migration has costs in terms of survival, migrants will be selected to ensure numerical compensation by reaching sexual maturity earlier or having higher annual reproductive outputs. ...
