Islands are weird, isolated from the continents and their ecosystems, they are home to very distinctive biotic communities, and sometimes unique species only found on that single island or group of islands, what are known as endemic species. The patterns of how islands are colonized by species is explained by the theory of island biogeography which says the number of species on an island is determined by its size (target effect) and proximity (distance effect) to a continent and is a relationship between immigration and extinction rates. Island Biogeography can also be applied to conservation biology and reserve design, larger and closer together reserves are better for wildlife.

This is Backyard Expeditions. Here you can find wildlife footage and short documentaries on the natural world. Nature is full of surprises, often amazing things are happening just feet from you door. I am a biology student who was inspired by the likes of the BBC natural history unit, PBS, and animal planet as a Child. I have also long been a hobbyist photographer, filming interesting things over time. My goal is to document interesting behavior and highlight interesting species I encounter both in exotic locations, and on backyard expeditions.
