"What document": I was somehow started working thermal issues in my first year. I quickly realized temperatures and humidity are connected in the bee-hive system, year round. Humidity issues led to the more general year round water requirements. After 4 winters I am learning about homeostasis including CO2, propolis, vapor pressure and how to achieve homeostasis via hive design. I am slowly studying my recent discovery "Homeostasis: Humidity and water relations in honeybee colonies ( Apis mellifera)" by Micheal B Ellis, University of Pretoria, November 2008. It is a masters thesis and so far very good IMO. I buttress this paper with other more recent technical reports and my own crude testing efforts at the hive level.
