I can't recommend Alan Braddock's A Keener Perception highly enough. It might be the one breakthrough book on visual art and ecology that art history needs to get into the game. There are some wonderful essays in here. Alan's is marvelously complex. And Christoph Irmscher's one about Agassiz's illustrator vs. Haeckel is fantastic. They both draw Medusae but Agassiz's illustrator does so with an uncanny inhuman delicacy, almost photographic.
