Book ChapterDOI
Optimal Bird Migration: The Relative Importance of Time, Energy, and Safety
Thomas Alerstam,Åke Lindström +1 more
TL;DR: “Optimization is the process of minimizing costs or maximizing benefits, or obtaining the best possible compromise between the two,” (R. McNeill Alexander 1982).
Journal ArticleDOI
Long-distance migration: evolution and determinants
TL;DR: From this expos it is clear that research on migration warrants a multitude of techniques and approaches for a complete as possible understanding of a very complex evolutionary syndrome.
Journal ArticleDOI
Optimum fuel loads in migratory birds: distinguishing between time and energy minimization
TL;DR: The total energy cost of migration is roughly divided between flight and stopover as 1:2, probably with a relatively longer stopover time in larger species and strong selection pressures to optimize the fuel accumulation strategies during stopover episodes are expected.
Journal ArticleDOI
When and where does mortality occur in migratory birds? Direct evidence from long- term satellite tracking of raptors
Raymond H. G. Klaassen,Raymond H. G. Klaassen,Mikael Hake,Roine Strandberg,Ben J. Koks,Christiane Trierweiler,Klaus-Michael Exo,Franz Bairlein,Thomas Alerstam +8 more
TL;DR: It is suggested that events during the migration seasons have an important impact on the population dynamics of long-distance migrants, and mortality during spring migration may account for short-term annual variation in survival and population sizes, while mortality during autumn migration may be more important for long-term population regulation.
