Hey guys I really need help with this project I have on the biodiversity of Vietnam. If anyone knows what this means please help!:

 

Trends in the geographical extent of selected biomes, ecosystems, and habitats. Explain anyone??

[John]

I'm taking it to essentially mean changes in where certain organisms live, how large an area they inhabit, etc.

 

As an example, our climate's current warming trend has resulted in some species appearing in places they've never lived before as they move further away from the equator. Therefore, the geographical extent of these species' habitats has changed over time.
