rangebreadth

Rangebreadth is a term used in ecology to describe the geographical distribution of a species or a population. It refers to the extent of the area in which a species can be found. This can be measured in various ways, such as the total area occupied by a species, the latitudinal or longitudinal span of its distribution, or the number of distinct habitats it inhabits.

Species with a wide rangebreadth are considered cosmopolitan or widespread, meaning they can survive and reproduce in a variety of environments across large geographical areas. Conversely, species with a narrow rangebreadth are endemic or restricted, found only in specific, often limited, locations. Factors influencing rangebreadth include a species' ability to tolerate different environmental conditions, its dispersal capabilities, and the presence of barriers to movement.

Understanding rangebreadth is crucial for conservation efforts. Species with limited rangebreadth are often more vulnerable to extinction because they may be highly susceptible to localized threats such as habitat loss or climate change. Monitoring changes in rangebreadth can also provide insights into the health of ecosystems and the impacts of environmental stressors.
