Revisiting Johnson 1993

In a paper published in Ecological Applications in 1993, Nancy Collins Johnson showed, experimentally, that fertilization of soil leads to the selection of Arbuscular Mycorrhizal (AM) fungi that are inferior mutualists. Johnson found that fertilization, both, alters the species composition of AM fungal communities and that big bluestem plants colonized with AM fungi and other … Continue reading Revisiting Johnson 1993

Revisiting Wilcove 1985

In a paper published in Ecology in 1985, David Wilcove provided experimental evidence in support of the idea that nest predation could be the cause for the decline of migratory songbirds in small woodlots in North America. Using fresh quail eggs places in artificial nests, Wilcove showed that predation was higher in smaller than in … Continue reading Revisiting Wilcove 1985

Revisiting Whittaker et al. 2001

In a paper published in the Journal of Biogeography in 2001, Robert Whittaker, Katherine Willis and Richard Field attempted to develop a "general, hierarchical theory of species diversity" that overcame what they saw as weaknesses of diversity theory at the time: failures to distinguish different response variables and adequately account for geographical scale. Seventeen years … Continue reading Revisiting Whittaker et al. 2001

Revisiting Haddad et al. 2003

In a paper published in Ecology in 2003, Nick Haddad,  David Bowne, Alan Cunningham, Brent Danielson, Douglas Levey, Sarah Sargent and Tim Spira, synthesized findings from a large-scale experiment to show that corridors aided movement between habitat patches, although the strength of the effect varied across taxa. Fourteen years after the paper was published, I … Continue reading Revisiting Haddad et al. 2003

Revisiting Gillespie 2004

In a paper published in Science in 2004, Rosemary Gillespie demonstrated that both dispersal and in situ speciation contribute to accumulation of species numbers of Tetragnathid spiders on Hawaiian islands. Moreover, accumulation, whether through dispersal or speciation, happens in a way that no island contains more than one species of a particular ecomorph, i.e. in … Continue reading Revisiting Gillespie 2004

Revisiting Scheffer et al. 2001

In a paper published in Nature in 2001, Marten Scheffer, Steve Carpenter, Jonathan Foley, Carl Folke and Brian Walker reviewed the evidence for large-scale shifts between alternate stable states in different ecosystems, the patterns that emerge from such shifts, and its implications for the management of these ecosystems. Fifteen years after the paper was published, … Continue reading Revisiting Scheffer et al. 2001

Revisiting Karban et al. 2000

In a paper published in Oecologia in 2000, Richard Karban, Ian Baldwin, Kimberly Baxter, Grit Laue and Gary Felton experimentally demonstrated that plants that had not been attacked by herbivores could sense and respond, by upping their defenses, to cues released by neighboring plants that had been attacked. Seventeen years after the paper was published, … Continue reading Revisiting Karban et al. 2000
