BIOSC 0370 Lecture Notes - Lecture 40: Endemism, Insular Biogeography
Document Summary
Talking about structure of inal exam on monday. 98 percent of its mammals live nowhere else same idea for other things. Hotspot size it is going down and only part is protected. Global hotspots areas with high endemism and high human operaion. These hotspots contain 44 percent of all plant species and 35 percent of all terrestrial vertebrates. They have a lot of biodiversity in aggregate in only 1. 4 percent of earth s land area. Human alteraion may be important to hotspots i am not sure. Up to 200 species go exinct every day. Any spaially isolated community can operate as an island. Sample areas of diferent sizes and count number of species. Then plot the number of species as a funcion of area. C is a constant depending on group and unit of measurement. Z is the slope of the line relaing s and a. Log s = log c + zlog a.
