Dispersal refers to the process by which organisms spread from their original location to new areas. This can occur through various means, such as wind, water, or animal movement. Dispersal is crucial for species survival, as it helps reduce competition for resources and allows populations to colonize new habitats. In ecology, dispersal can influence biodiversity and ecosystem dynamics. For example, plants like dandelions use wind to disperse their seeds, while animals like birds may carry seeds to different locations. Understanding dispersal patterns helps scientists study how species adapt to changing environments and the impacts of climate change.
