Journal ArticleDOI
Approaching a state shift in Earth’s biosphere
Anthony D. Barnosky,Elizabeth A. Hadly,Jordi Bascompte,Eric L. Berlow,James H. Brown,Mikael Fortelius,Wayne M. Getz,John Harte,Alan Hastings,Pablo A. Marquet,Neo D. Martinez,Arne Ø. Mooers,Peter D. Roopnarine,Geerat J. Vermeij,John W. Williams,Rosemary G. Gillespie,Justin Kitzes,Charles R. Marshall,Nicholas J. Matzke,David P. Mindell,Eloy Revilla,Adam B. Smith +21 more
TL;DR: Evidence that the global ecosystem as a whole is approaching a planetary-scale critical transition as a result of human influence is reviewed, highlighting the need to improve biological forecasting by detecting early warning signs of critical transitions.
Journal ArticleDOI
Weak trophic interactions and the balance of nature
TL;DR: The results show that weak to intermediate strength links are important in promoting community persistence and stability, and data on interaction strengths in natural food webs indicate that food-web interaction strengths are indeed characterized by many weak interactions and a few strong interactions.
Journal ArticleDOI
Chaos in a Three-Species Food Chain
Alan Hastings,Thomas M. Powell +1 more
TL;DR: In this article, a continuous time model of a food chain incorporating nonlinear functional (and numerical) responses exhibits chaotic dynamics in long-term behavior when biologically reasonable parameter values are chosen.
Journal ArticleDOI
The spatial spread of invasions: new developments in theory and evidence
Alan Hastings,Kim Cuddington,Kendi F. Davies,Christopher J. Dugaw,Sarah C. Elmendorf,Amy L. Freestone,Susan Harrison,Matthew D. Holland,John G. Lambrinos,Urmila Malvadkar,Brett A. Melbourne,Kara A. Moore,Caz M. Taylor,Diane M. Thomson +13 more
TL;DR: It is shown that invasive species spread is a much more complex process than the classical models suggested, as long range dispersal events can have a large influence on the rate of range expansion through time.
Journal ArticleDOI
Ecological and evolutionary insights from species invasions
Dov F. Sax,John J. Stachowicz,James H. Brown,John F. Bruno,Michael N Dawson,Steven D. Gaines,Richard K. Grosberg,Alan Hastings,Robert D. Holt,Margaret M. Mayfield,Mary I. O'Connor,William R. Rice +11 more
TL;DR: How the study of invasions can help to inform the understanding of applied problems, such as extinction, ecosystem function and the response of species to climate change is emphasized.
