Revisiting Peterson et al. 1999

In a paper published in Science in 1999, A. Townsend Peterson, Jorge Soberón and Víctor Sánchez-Cordero presented strong evidence for niche conservatism in 37 sister taxon pairs of mammals, birds and butterflies on either side of the Isthmus of Tehuantepec in Mexico. These results suggested that speciation initally took place along geographic dimensions and ecological … Continue reading Revisiting Peterson et al. 1999

Revisiting Stachowicz et al. 1999

In a paper published in Science in 1999, Jay Stachowicz, Robert Whitlach and Richard Osman showed, using experimental communities of sessile marine invertebrates that invasion success was lower in more species rich communities. The like reason for this pattern was that space, which was the limiting resource in the system, was more fully and efficiently … Continue reading Revisiting Stachowicz et al. 1999

Revisiting Felsenstein 1985

In a paper published in The American Naturalist in 1985, Joseph Felsenstein proposed a new method – phylogenetically independent contrasts – that allowed the incorporation of phylogenetic information into comparative analyses. Using Felsenstein’s method, biologists could overcome the statistical problem of non-independence of species due to shared ancestry. Thirty-one years after the paper was published, … Continue reading Revisiting Felsenstein 1985

Revisiting Gurevitch et al. 1992

In a paper published in The American Naturalist in 1992, Jessica Gurevitch, Laura Morrow, Alison Wallace and Joseph Walsh presented the results of what was, arguably, the first meta-analysis in ecology, of field competition experiments published in six leading ecology journals over a 10-year period. Gurevitch and colleagues found that, overall, competition had a strong … Continue reading Revisiting Gurevitch et al. 1992

Revisiting Hurlbert 1984

In a paper published in Ecological Monographs in 1984, Stuart Hurlbert examined 176 experimental studies in ecology and found that 27% suffered from 'pseudoreplication' - the use of statistical statistical testing in situations in which treatments were not replicated or the replicates were not independent. When only studies that used inferential statistics were considered, the … Continue reading Revisiting Hurlbert 1984

Revisiting Carvalho & Vasconcelos 1999

In a paper published in Biological Conservation in 1999, Karine Carvalho and Heraldo Vasconcelos examined the effects of forest fragmentation on litter-dwelling ants in Central Amazonia. Their results suggested that litter ant communities were structured both by edge and isolation effects in these fragments. Twenty-one years after the paper was published, I asked Karine Carvalho … Continue reading Revisiting Carvalho & Vasconcelos 1999

Revisiting Coulson et al. 2001

In a paper published in Science in 2001, Tim Coulson, Edward Catchpole, Steve Albon, Byron Morgan, Josephine Pemberton, Tim Clutton-Brock, Mick Crawley, and Bryan Grenfell examined the effect of density, climate and demography on population fluctuations in Soay sheep on the St. Kilda islands in the United Kingdom. Coulson and colleagues' found that age and … Continue reading Revisiting Coulson et al. 2001

Revisiting Losos et al. 1998

In a paper published in Science in 1998, Jonathan Losos, Todd Jackman, Allan Larson, Kevin de Queiroz, and Lourdes Rodrı́guez-Schettino, using morphometric and phylogenetic analyses, showed that the same set of habitat specialists or "ecomorphs" of Anolis lizards had evolved independently on four Greater Antillean islands, suggesting that adaptive radiation in similar environments can produce … Continue reading Revisiting Losos et al. 1998

Revisiting Benkman 1999

In a paper published in The American Naturalist in 1999, Craig Benkman demonstrated the existence of a selection mosaic with coevolutionary hotspots in a population of the Rocky Mountain lodgepole pine. Where red squirrels are present, they drive selection on lodgepole pine cone structure. In locations where they are absent, red crossbills are more abundant … Continue reading Revisiting Benkman 1999
