Species distribution and why it changes

Species distribution and why it changes

Flowchart showing temperature, water availability and atmospheric gases affecting survival, reproduction and competition, leading to species distribution changes such as butterfly range expanding, amphibians declining at a dried pond, and sensitive lichens absent where sulfur dioxide is high

Species distribution means where a species is found and how common it is in different places. It includes the species' range and its abundance, not just whether it is present or absent.
