BIOL2010 Lecture 16: Lecture 16
Document Summary
Community: all the species in the same area potentially interacting with each other, predictability. Lecture 16: focus on reproduction than protection, have high rmax value. It"s (cid:374)ot (cid:271)la(cid:272)k a(cid:374)d (cid:449)hite, there is e(cid:448)ide(cid:374)(cid:272)e that support (cid:271)oth of the(cid:373: because nature is more complicated, a strict clements view is incorrect. If you go across elevation gradients, going up the mountain you should find different species at different elevation. It may be different at different points of the mountain even if the elevation is the same. Species: evolutionarily independent population or group of populations, biodiversity on a tree of life. Independent trajectory means that a branch will grow and never reconnect. Speciation: splitting event that creates 2 or more distinct species from a single common ancestor, 1 branch splitting into 2. If populations are not sympatric: are in the same geographic area. Lecture 16: giraffes, colors are for different populations with these different phenotypes.
