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 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

Revisiting Terborgh et al. 2001

In 2001, John Terborgh, Lawrence Lopez, Percy Nuňez, Madhu Rao, Ghazala Shahabuddin, Gabriela Orihuela, Mailen Riveros, Rafael Ascanio, Greg Adler, Thomas Lambert and Luis Balbas published a paper in Science demonstrating a trophic cascade on predator-free islands, which were created as a result of the construction of a dam. Fifteen years after the paper was … Continue reading Revisiting Terborgh et al. 2001

Revisiting Kruess and Tscharntke 1994

In 1994, Andreas Kruess and Teja Tscharntke published a paper in Science reporting the results of their experiments looking at how habitat fragmentation affects diversity and natural pest control in agricultural fields. Twenty-two years later, I spoke to Teja Tscharntke about the making of this study and what we have learnt about habitat fragmentation effects … Continue reading Revisiting Kruess and Tscharntke 1994
