My computer did not work 15 days ago, but I did not have a rest. I was busy with reading the book “Ecological Stoichiometry: The Biology of Elements from Molecules to the Biosphere”. I have finished it already. Even though the book is hard for me, especially some models, I got more new information. The book is like a gate for me to enter the “Ecological Stoichiometry” field. I like the question “What is the grass?” In China, the rangeland are not gotten chemical fertilization, I do not know what the destiny of that rangeland ecosystem is finally.
I remembered, I dreamed one night, long time ago, that I took part in a conference, and I got a information that N and P control the biodiversity in the natural world, especially P. I know it is just a dream, I am not sure it is right, but “Ecological Stoichiometry” may be helpful to explore this question.
