Reductionistic Research Strategies and Their Biases in the Units of Selection Controversy, a prophetic characterization of the explanatory tenor of modern evolutionary biology. It preceded August Weismann’s doctrine of the continuity of the germ plasm advanced in his inaugural lecture in 1883 by some five years. As Weismann’s views became one of the anchor points of the modern ‘neo-Darwi

,Ecology — A Mixture of Pattern and Probabilism, organs to ethology and physiology, and of cells and molecules to cell biology and molecular biology, respectively. Such a definition is clearer than the general statement “The relationship of organisms to their environment” and recognises the separation of biology into a series of ‘horizontal level

Useful Concepts for Predictive Ecology,ich, by definition, are unfalsifiable. Both types of ideas are necessary for a scientist, but only theories comprise a science. Nevertheless, in ecology, concept and theory are confused to the point that non-predictive ideas impede scientific advance. In this essay, I will try to distinguish between

The Domain of Laboratory Ecology,e concepts and, ideally, may have the same ultimate goals, but they are also distinct, not only in the scientific tools they use, but even in the types of questions best addressed by each one. This paper is concerned in particular with laboratory ecology and the relations, and distinctions, between

Null Hypotheses in Ecology,of interest. Null hypotheses are reference points against which alternatives should be contrasted. They are used not only in statistics but in all sciences. “This hypothesis…is… characteristic of all experimentation” (Fisher 1935). In physics for example, an important null hypothesis of the post-New

Randomness and Perceived-Randomness in Evolutionary Biology,n the development of new connections between the concept of computational complexity and the idea of the degree of randomness of a sequence as connected with the complexity of the simplest program capable of generating that sequence (Chaitan, 1975).

I discuss various misinterpretations of deduction. Factors regulating density have a different signifi
