Study Notes
Partial Migration
- Partial migration is a selection process that divides migrating animals from non-migrating animals.
- Timing of migration is also affected by selection.
- Long-distance migrants face challenges.
Orientation and Navigation
- Orientation is the process of determining and maintaining a proper direction.
- Navigation is the process of finding and moving towards a particular location.
- Animals can use various cues to navigate, such as the sun, stars, skylight polarization patterns, sunsets, and the geomagnetic field.
- Creating a mental map aids in navigation.
Bicoordinate Migration
- Bicoordinate migration uses a type of mental map with environmental gradients to determine direction.
- One gradient indicates north-south direction, and another indicates east-west direction.
- Migratory direction is also influenced by genes.
