The Unified Neutral Theory of Biodiversity and Biogeography, published as a monograph in 2001, by Stephen Hubbell, is considered one of the most important recent developments in Ecology. What is, probably, less well-known is that the ideas in the book were originally laid out in a paper published in the journal Coral Reefs in 1997. … Continue reading Revisiting Hubbell 1997

Revisiting Werner et al. 1983
In a paper published in Ecology in 1983, Earl Werner, James Gilliam, Donald Hall and Gary Mittelbach, showed experimentally that small bluegill sunfish, which are vulnerable to predation by bass, showed an observable shift in foraging behaviour when bass are present choosing to forage in less-profitable habitats. Thirty-six years after the paper was published I … Continue reading Revisiting Werner et al. 1983
Revisiting Heinrich 1976
In a paper published in Ecological Monographs in 1976, Bernd Heinrich demonstrated, through careful observation and experiment on marked individuals, how bumblebees develop specialization in their foraging at the individual level, and examined the costs and benefits of of specialization through comparisons with other bee species. Forty years after the paper was published, I spoke … Continue reading Revisiting Heinrich 1976
Revisiting Bolnick et al. 2003
In a paper published in The American Naturalist in 2003, Daniel Bolnick, Richard Svanbäck, James A. Fordyce, Louie Yang, Jeremy Davis, Darrin Hulsey and Matthew Forister reviewed studies that examined individual specialization on resource use and quantified how much inter-individual variation contributes to a species' niche width. Based on their review, they discuss the ecological, … Continue reading Revisiting Bolnick et al. 2003
Revisiting Legendre 1993
In a paper published in Ecology in 1993, Pierre Legendre highlighted and proposed solutions to the problem of "spatial autocorrelation" in the statistical analysis of ecological data. The methods proposed by Legendre have had a lasting impact on the analysis of field ecological research. Twenty-five years after the paper was published, I asked Pierre Legendre … Continue reading Revisiting Legendre 1993
Revisiting Hamilton and Zuk 1982
In a paper published in Science in 1982, William Hamilton and Marlene Zuk showed positive associations between the level of chronic blood infections and display characteristics across North American Passerines. Based on these results they proposed a "good genes" model of sexual selection (Hamilton-Zuk Hypothesis): display characteristics used in mate selection are indicators of parasite … Continue reading Revisiting Hamilton and Zuk 1982
Revisiting Rahbek 1995
In a paper published in Ecography in 1995, Carsten Rahbek critically examined the evidence for what was then believed to be a general pattern: species richness reduces with increasing altitude. Rahbek showed that through a process of "citation inbreeding" evidence from just a few studies had become established as a general pattern of biogeography. Rahbek … Continue reading Revisiting Rahbek 1995
Revisiting Lande and Arnold 1983
In 1983, following up on a little-known paper published by Karl Pearson eighty years earlier, Russell Lande and Stevan Arnold, developed statistical methods to measure selection based only on changes in population phenotypic traits within a generation. Thirty-six years after the paper was published, I asked Stevan Arnold about the making of this paper, his … Continue reading Revisiting Lande and Arnold 1983
