Visual representation of nature - ASEH2014

I subscribe to quite a few mail lists including the H-ENVIRONMENT list at H-NET.MSU.EDU. The post below caught my attention being always intrigued by diagrams and how they are applied. Caleb Wellum's post - copied below with thanks - stood out, not so much for the panel and being there (San Francisco!) as the theme. I've added links plus an image below and edited slightly:

Dear Colleagues,

I am organizing a panel about the visual representation of nature (and the politics of different representational forms) for ASEH 2014. My paper will examine H.T. Odum's energy diagrams in his popular 1970s works "Environment, Power, and Society" and "Energy: Basis for Man and Nature."
Michael Clemens will discuss nature documentaries at the National Film Board of Canada in the 1960s and 1970s and Duygu Kasdogan will be doing a visual ethnography of biofuels. We are looking for a 4th person to round out our panel. Your paper can be about any period, region, or form of visual representation.

Sincerely
Caleb Wellum
