Revisiting Levine 2000

In 2000, Jonathan Levine published a paper in Science reporting the results of a field experiment that showed that the impact of species diversity on invasive diversity depends on spatial scale. At small scales, the removal of species reduces invasion resistance, but at community-wide scales, the more diverse a community is the more likely it … Continue reading Revisiting Levine 2000

Revisiting Clutton-Brock and Harvey 1977

In 1977, Tim Clutton-Brock and Paul Harvey published a paper in the Journal of Zoology reporting the results of their comparative analysis of the ecology and social organization of 100 primate species. This study was probably the first to statistically account for the non-independence of data as a result of species' phylogenetic relationships, a theme … Continue reading Revisiting Clutton-Brock and Harvey 1977

Revisiting Seehausen et al. 1997

In 1997, Ole Seehausen, Jacques van Alphen and Frans Witte published a paper in Science providing evidence for a novel route through which eutrophication can reduce species diversity. Species of cichlid fish in Lake Victoria are capable of interbreeding, but mate choice based on coloration and subsequent assortative mating keeps species distinct. Seehausen and colleagues found … Continue reading Revisiting Seehausen et al. 1997
