- Mosquito distribution exemplifies how environmental factors influence species distribution.
- Mosquitoes are found at similar latitudes globally.
- The example of mosquito distribution is for illustration purposes only, not for memorization.
- Another example of environmental impact on species distribution is the arctic tree line.
- Environmental changes can include variations in water availability, temperature, and atmospheric gas composition.
