Zusammenfassung:
Migration is ubiquitous in the animal kingdom. This seasonal long-distance movement of individuals is one of the world’s most amazing biological phenomenon, involving billions of individuals from various taxa, that move thousands of kilometers sometimes across continents.
Our knowledge about the genetic basis of migration or migratory traits (e.g., timing, distance, direction) has traditionally been limited to crossbreeding and displacement experiments. Recent technological advances s in genomics mean that we are now at a turning point where our understanding can evolve from phenotypic to genomic approaches. This newly-emerging field of migration genomics will allow us to understand the genetic architecture of migratory traits in much greater detail. This article integrates current knowledge of the genetic basis of migration using examples from various taxa and diverse disciplines including behavior, ecology, evolution, molecular biology and genomics.
