Ecotasia's video: Why are Islands so Weird Adaptive Radiation Island Biogeography and Invasive Species

Islands, why are they so strange? Surrounded by water they come in all shapes, climates, sizes, and distances from the mainland. Many islands, particularly tropical ones, are associated with sun, white sand beaches, azure waters, and relaxation; however islands are also often quite strange places if you bother to get off your pool chair and really look at the organisms that inhabit them. Even a spit of land right next to a continent might feel a little off, one species relatively uncommon on the mainland might be everywhere on an island, while others are completely absent. The further you go from the continents through the stranger island organisms become, so what oddities might inhabit the world’s most remote chain of islands, the Hawaiian Islands? and What makes islands have such weird fauna?

Welcome to Ecotasia! On this channel you can find wildlife footage and short documentaries on the natural world. I am an early career biologist who was inspired by the likes of the BBC Natural History unit, PBS, and Animal Planet as a child and then more recently by various nature YouTube channels to share my love for animals and nature. My goal is to document and highlight the interesting ecology and behavior of organisms I encounter, as well as cover and elucidate conservation and biological topics.
