Coastallineage

Coastallineage is a term used to describe the genetic or evolutionary history of populations or species that inhabit coastal environments. It focuses on the unique adaptations and historical movements of organisms living along the interface between land and sea. This can encompass a wide range of species, from marine invertebrates and fish to coastal birds and mammals, as well as terrestrial plants and animals that are strongly influenced by proximity to the ocean.

Research into coastallineages often investigates factors such as gene flow, isolation, and adaptation to specific coastal conditions like salinity, tidal fluctuations, and wave action. Understanding coastallineages can provide insights into patterns of speciation, biogeography, and the resilience of populations to environmental changes. For instance, studies might examine how populations of a particular species separated by a bay or headland have diverged genetically over time, or how species have colonized new coastlines through dispersal events. The concept is relevant in fields such as evolutionary biology, marine ecology, and conservation science, helping to inform management strategies for coastal biodiversity.
