Migration in organisms refers to the directed, typically seasonal or life-stage–dependent movement of individuals or populations between distinct geographic regions, often driven by spatiotemporal variation in resources, breeding opportunities, or environmental conditions. It is characterized by relatively long-distance, persistent movements with clear origin and destination areas, underpinned by evolved orientation and navigation mechanisms (e.g., celestial, geomagnetic, olfactory cues). Migration can be obligate or facultative, partial or complete within a population, and plays critical roles in gene flow, metapopulation dynamics, ecological connectivity, disease spread, and responses to climate and habitat change across taxa including animals, plants (via propagule movement), and microorganisms.
Murdoch University researchers call for wildlife-friendly solar farm designs to protect biodiversity amid global renewable energy expansion.

The histories of sled dogs and humans in the Arctic have been intricately linked for thousands of years, so it is no surprise that the migration patterns of these dogs mirror those of humans through the Arctic. Sled dogs ...
Certain migratory species of sharks may remain swimming and feeding in Atlantic Ocean waters in areas of the northeast coast for longer periods of time later into fall before they head toward southern waters. Led by researchers ...
