Document Summary

Sink patch has a net flow into it. Big patch is the source path where all the organisms are. Stepping stone patch --> even if it"s small it causes extra migration because species jump large patches through stepping stone patches. This migration, subpopulations of species can go to extinction by. Necessary of biology is why certain species are found together typological community concept individual hypothesis. Each species is independent of each other. Robert whittaker tested the hypothesis by going to mountains where gradients are found he studied tree species and checked elevation. Robert proved gleeson was the correct one by d graph being correct. Graph a was clemson (look at this on notes and also look at the names bold names) Curtis also proved gleeson by multivariate statistics. Margaret proved trees migrate independently --> gleeson wins. Basically there is continuous variation in environments not discrete.
