Document Summary

Lichens reproductive structures - produce multicellular spores symbiosis b/w fungas and oxidative phototroph (cyanbacteria or algae) creator of valcano truly primary succession massive explosion that took out t the 1700s lichens grown. High uv adapted he just made really smart guesses to how they looked like first to draw the tree of life: ernst haeckel"s lichen drawings, haeckel did the first. Nostoc - nitrogen fixation whenever someone needs phosophorous will get a fungal symbiont. Lichens - cnp: first thought to be only an algal-fungal symbiosis, primary producer in symbiosis can be a cyanobacteria or algae (both do oxidative photosynthesis) Responsible for carbon supply: the cyanobacteria is usually nostoc. Transect is like time series took these sections (in square) -> old /new habitat good idea on how they grow, their whole cronosequence, from oldest to newest. Newer (or edge) community has lower diversity than old (central) community looked at diversity and bands.
