Revisiting Harrison et al. 1988

In a paper published in The American Naturalist in 1988, Susan Harrison, Dennis Murphy and Paul Ehrlich demonstrate the existence of a metapopulation of the Bay checkerspot butterfly, a rare species whose larvae feed on plants that grow on patches of serpentine soil. Using a combination of field surveys, simulation modelling and historical information, Harrison … Continue reading Revisiting Harrison et al. 1988

Revisiting Hobbie 1996

In a paper published in Ecological Monographs in 1996, Sarah Hobbie reported the results of her laboratory experiments on the effect of increased temperature and species composition on litter decomposition in the Alaskan Tundra. Hobbie found that increased temperature led to "increased rates of soil and litter respiration, litter decomposition, litter nitrogen release, and soil … Continue reading Revisiting Hobbie 1996

Revisiting Jackson et al. 2001

In a paper published in Science in 2001, Jeremy Jackson, Michael Kirby, Wolfgang Berger, Karen Bjorndal, Louis Botsford, Bruce Bourque, Roger Bradbury, Richard Cooke, Jon Erlandson, James Estes, Terence Hughes, Susan Kidwell, Carina Lange, Hunter Lenihan, John Pandolfi, Charles Peterson, Robert Steneck, Mia Tegner and Robert Warner showed, using paleoecological, archeological and historical data, that … Continue reading Revisiting Jackson et al. 2001

Revisiting Bascompte et al. 2003

In a paper published in PNAS in 2003, Jordi Bascompte, Pedro Jordano, Carlos Meli├ín and Jens Olesen investigated the structural organisation of 52 mutualistic networks and found them to be highly nested, resulting in communities centred around a smaller core of interactions. Bascompte and colleagues also found that communities that contained a greater number of … Continue reading Revisiting Bascompte et al. 2003

Revisiting Colwell and Lees 2000

In a paper published in Trends in Ecology & Evolution in 2000, Robert Colwell and David Lees reviewed the conceptual and empirical literature on the influence of the "mid-domain effect" - geometric constraints in geographic patterns of species richness caused by physiological and physiographical boundaries. Sixteen years after the paper was published, I asked Robert … Continue reading Revisiting Colwell and Lees 2000
