On Comparing Comparative Methods
Annual Review of Ecology and Systematics, 1992Virtually every field in the biological sciences uses comparative, cross-taxonomic analysis. Unlike experimental study, comparative analyses have historically relied on simple correlation of traits across species. In the past ten years, especially since publication of a few landmark papers (e.g. 13, 24), this straightforward comparative methodology has

Abstract Bird species exhibit enormous diversity in morphology, behaviour, and ecology. In this book we attempt to explain why variability in life-history traits, mating systems, and extinction patterns exists across a wide range of bird species.

The internal comparator method
Analytical and Bioanalytical Chemistry, 2004An internal comparator method is proposed which offers reliable instrumental neutron activation analysis (INAA) results for samples with an irregular geometry and/or measured at the closest position to the Ge detector. Because the selected internal comparator in the sample analyzed will receive exactly the same thermal neutron flux as the other ...

3. Comparative Research Methods
2020This chapter examines the ‘art of comparing’ by showing how to relate a theoretically guided research question to a properly founded research answer by developing an adequate research design. It first considers the role of variables in comparative research, before discussing the meaning of ‘cases’ and case selection.

Comparative methods and evolution
2002Comparative biology provides a framework for the study of evolution, by seeking answers to the question of why traits evolved. However, the difficulties of making inferences about the biological causes of trait variation and covariation resulted in the development of very different approaches to comparative analyses, which are outlined and contrasted ...
