Island Biogeography

Part I, island biogeography in a World Regional here to watch part II, why island biogeography matters in places that aren't on islands.  archived at:

Like World Regional Geography, Bio-geography is closely related to that of World Regional Geography. Species that live on islands are prone to extinction.  While this so, they is very little competition of survival as there are on mainlands. With the Sunda Shelf in Asia, some species that can be found on one side of the continent can also be found in Australia. While we are separated by sea, rivers, and oceans, animals that can be found in one area of the world, can also be found on another land. Respectively, animals that were exclusive to one country are appearing on other lands where they aren't known to dwell on.

It is fascinating to see how life evolves differently on isolated islands. The unique biomes often lack enough diversity to fill certain roles, so the animals move to fill them. For example, the komodo dragon was able to evolve to its large size because there was not large predator sitting on top of the food chain to prevent its growth. Sadly, the unique nature of island biogeography also makes it much more delicate, and species are much more likely to become extinct.

There are times where I wish certain species don't spread.  Other times I understand the migration and think it's great.  If humans died out then I believe all species would flourish just as Sir Ken Robinson says.

Boundary conditions

Boundary conditions | MrsWunder's Blog |
PULL a spring, let it go, and it will snap back into shape. Pull it further and yet further and it will go on springing back until, quite suddenly, it won't....

A useful discussion on limits of the planet

Seth Dixon's curator insight, February 11, 2013 8:23 AM

This is an interesting article discussing the limits that the Earth's physical systems have and the importance not exceeding any tipping point that could destabilize the planet if we "overstrech the springs."

Angus Henderson's curator insight, February 11, 2013 11:49 AM

An interesting counter-balance to the work of the Planetary Boundaries group.
