Biology is science, ecology is not, just making that clear. For exaples, once it was said that all ravens are black. Then one day, a white one was seen, so they corrected it. This is not a scientific method, that is guesswork.
I missed this dicussion the first time around, and I want my say. Just so we know where am coming from, I am a behavioural ecologist investigating the meachanisms that determine host-choice decisions in parasitoid Hymenoptera. Ecology is a science, unfortunately the further away you get from Maths the less repeatable your experiments are; there is more variation and the same phenomena are less likely to occur twice. In a physics experiment everyone will observe the same thing, in a chemistry one most of the people will observe the same thing, and in a biology experiment a lower proportion of people will observethe same thing. This has nothing to do the science being soft and purely to do with the number of factors involved in the observation.
However, in ecology, unlike maths for example, what we study is highly observeable. And we can repeat our experiments until we discern which phenomena is the most likely to occur and what factors result in the different variations. Ecology is the culmination of this with most experiments taking years worth of data, as is similar for medicine, sociology or anthropology; while chemistry and physics have much faster turn-overs as they have less factors to consider and the time scale that their observations occur on at much shorter.
OT: One of my colleages, a mathetician working in the evolution department, is in fact using biological knowledge as both an art and a science. He is using mathematics, combined with the stochastic behaviour of bacteria (yes, bacteria behave), to predict and control fractal patterns in colonial expansion. He is then using the fractal patterns, and photos thereof, as part of his art portfolio.
