Journal ArticleDOI
Functional diversity: back to basics and looking forward
Owen L. Petchey,Kevin J. Gaston +1 more
TL;DR: It is suggested that non-significant results have a range of alternate explanations that do not necessarily contradict positive effects of functional diversity, and areas for development of techniques used to measure functional diversity are suggested.
Journal ArticleDOI
Functional diversity (FD), species richness and community composition
Owen L. Petchey,Kevin J. Gaston +1 more
TL;DR: A means for quantifying functional diversity that may be particularly useful for determining how functional diversity is related to ecosystem functioning is proposed, defined as the total branch length of a functional dendrogram.
Journal ArticleDOI
Biodiversity and resilience of ecosystem functions
Tom H. Oliver,Matthew S. Heard,Nick J. B. Isaac,David B. Roy,Deborah A. Procter,Felix Eigenbrod,Robert P. Freckleton,Andy Hector,C. David L. Orme,Owen L. Petchey,Vânia Proença,David Raffaelli,K. Blake Suttle,Georgina M. Mace,Berta Martín-López,Berta Martín-López,Ben A. Woodcock,James M. Bullock +17 more
TL;DR: A range of mechanisms underpinning the resilience of ecosystem functions across three ecological scales are identified and biodiversity, encompassing variation from within species to across landscapes, may be crucial for the longer-term resilience ofcosystem functions and the services that they underpin.
Journal ArticleDOI
Environmental warming alters food-web structure and ecosystem function
TL;DR: It is shown using microcosm experiments that extinction risk in warming environments depends on trophic position but remains unaffected by biodiversity, which suggests that high biodiversity buffers against the effects of environmental variation because tolerant species are more likely to be found.
Journal ArticleDOI
Interaction strengths in food webs: issues and opportunities
Eric L. Berlow,Anje-Margiet Neutel,Joel E. Cohen,Peter C. de Ruiter,Bo Ebenman,Mark C. Emmerson,Jeremy W. Fox,Vincent A. A. Jansen,J. Iwan Jones,Giorgos D. Kokkoris,Dmitrii O. Logofet,Alan J. McKane,José M. Montoya,Owen L. Petchey +13 more
TL;DR: The various ways in which the term ‘interaction strength’ has been applied are described and the implications of loose terminology and definition for the development of this field are discussed.
