Reading
one of the most valuable and informative books i have read recently is Morse's Behavioral Mechanisms in Ecology. some of my favorite chapters are competition between species - variability in foraging patterns - avoiding predation - territoriality. an estimable researcher who started his publishing career in 1956 on the night time activity of the snow bunting.
a valuable book about an estimable person i would recommend to my 13 grandchildren and especially Aubrey is Be Useful, by Arnold Shwarzenegger.
