Island Biogeography
A precise tool.
What is the Island Biogeography & How does it work?
Island biogeography is a theory that explains the distribution of species on islands in relation to their distance from mainland and size. The theory suggests that larger islands have more species than smaller ones, and closer islands have more species in common than those further apart.This model helps in understanding the balance between colonization and extinction rates, which are influenced by factors such as island size, distance from mainland, and environmental conditions.
S = c cdot A^z cdot e^{-d cdot D}
S = number of species, c = colonization rate, A = island area, z = area exponent, d = extinction rate, D = distance from mainland

Frequently Asked Questions
What is the Island Biogeography Calculator used for?
The Island Biogeography Calculator is used to estimate the number of species on an island based on factors like its area, distance from the mainland, colonization rate, and extinction rate.
How does island size affect species diversity according to this calculator?
According to the calculator, larger islands tend to have more species than smaller ones because they can support a higher number of individuals and ecosystems.
What is the role of distance from the mainland in the calculator’s model?
Distance from the mainland affects species diversity by influencing the rate at which new species colonize the island and the likelihood of existing species going extinct.
How do colonization rates impact the number of species on an island?
Higher colonization rates can lead to a greater number of species on an island, as more species are able to establish themselves over time.
What is the significance of the extinction rate in this model?
The extinction rate determines how quickly existing species disappear from the island. A higher extinction rate can reduce overall species diversity.
Can the calculator be used to predict changes in species diversity over time?
Yes, by adjusting parameters like colonization and extinction rates, the calculator can simulate how species diversity might change on an island over different periods.
What is the formula used in the Island Biogeography Calculator?
The formula used is S = c * A^z * e^(-d * D), where S is the number of species, c is the colonization rate, A is island area, z is the area exponent, d is the extinction rate, and D is distance from mainland.
