Size, foraging, and food web structureOwen L Petchey
Department of Animal and Plant Sciences, Alfred Denny Building, University of Sheffield, Western Bank, Sheffield S10 2TN, United Kingdom
Proc Natl Acad Sci U S A 105:4191-6. 2008..The model results support the hypothesis that individual behavior, subject to natural selection, determines individual diets and that food web structure is the sum of these individual decisions...
Trophically unique species are vulnerable to cascading extinctionOwen L Petchey
Department of Animal and Plant Sciences, Alfred Denny Building, University of Sheffield, Western Bank, Sheffield S10 2TN, United Kingdom
Am Nat 171:568-79. 2008..A positive correlation between a species' extinction probability and the importance of its loss defines high-risk species and should make their conservation a priority...
Body-size distributions and size-spectra: universal indicators of ecological status?Owen L Petchey
Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK
Biol Lett 6:434-7. 2010..The research conducted suggests that organismal size, with a generous helping of taxonomy, provides the most probable route to universal indicators of ecological status...
Fit, efficiency, and biology: some thoughts on judging food web modelsOwen L Petchey
Department of Animal and Plant Sciences, Alfred Denny Building, University of Sheffield, Western Bank, Sheffield S10 2TN, United Kingdom
J Theor Biol 279:169-71. 2011..Furthermore, we see an important but somewhat neglected role for experimental tests of models of food web structure...
The interacting effects of temperature and food chain length on trophic abundance and ecosystem functionOliver S Beveridge
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 2TN, UK
J Anim Ecol 79:693-700. 2010..Understanding and predicting the consequences of environmental change will require that indirect effects, trophic structure, and individual species' tolerances be incorporated into theory and models...
Mechanisms of temperature-dependent swimming: the importance of physics, physiology and body size in determining protist swimming speedOliver S Beveridge
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 2TN, UK
J Exp Biol 213:4223-31. 2010..Because encounter rates between protist predators and their prey are determined by swimming speed, temperature- and viscosity-dependent swimming speeds are likely to result in temperature- and viscosity-dependent trophic interactions...

Proc Natl Acad Sci U S A 103:13745-9. 2006....
Predicting the effects of temperature on food web connectanceOwen L Petchey
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 1SA, UK
Philos Trans R Soc Lond B Biol Sci 365:2081-91. 2010..We conclude that models of temperature effects on community structure and dynamics urgently require considerable development, and also more and better empirical data to parameterize and test them...
Infectious food websAndrew P Beckerman
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
J Anim Ecol 78:493-6. 2009..These data show the type of natural history knowledge necessary to advance our understanding of food web complexity, structure and dynamics...
Testing a biological mechanism of the insurance hypothesis in experimental aquatic communitiesDaniel J Leary
Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield, UK
J Anim Ecol 78:1143-51. 2009..Biodiversity, in terms of differences in species' responses to environmental fluctuations (i.e. functional response diversity) stabilizes community dynamics...
The effects of immigration and environmental variability on the persistence of an inferior competitorZachary T Long
Department of Ecology, Evolution, and Natural Resources, Rutgers University, 14 College Farm Road, New Brunswick, NJ 08901, USA
Ecol Lett 10:574-85. 2007..Our results suggest that an increase in temporal autocorrelation of environmental variability will cause regional processes to increasingly influence local interactions...
