Journal ArticleDOI
Trophic level asynchrony in rates of phenological change for marine, freshwater and terrestrial environments
Stephen J. Thackeray,Tim H. Sparks,Morten Frederiksen,Sarah J. Burthe,P. J. Bacon,James R. Bell,Marc S. Botham,Tom Brereton,Paul W. Bright,Laurence Carvalho,Tim H. Clutton-Brock,Alistair Dawson,Martin Edwards,J. Malcolm Elliott,Richard Harrington,David G. Johns,Ian D. Jones,James T. Jones,David I. Leech,David B. Roy,W. Andy Scott,Matt Smith,Richard J. Smithers,Ian J. Winfield,Sarah Wanless +24 more
TL;DR: In this article, the authors present a standardized assessment of 25 532 rates of phenological change for 726 UK terrestrial, freshwater and marine taxa and trophic levels and show that the majority of spring and summer events have advanced, and more rapidly than previously documented.
Journal ArticleDOI
From plankton to top predators: bottom-up control of a marine food web across four trophic levels.
Morten Frederiksen,Martin Edwards,Anthony J. Richardson,Anthony J. Richardson,N.C. Halliday,Sarah Wanless +5 more
TL;DR: These links are consistent with bottom-up ecosystem regulation and indicate how climate-driven changes in plankton communities can affect top predators and potentially human fisheries through the dynamics of key mid-trophic fish.
Journal ArticleDOI
The role of industrial fisheries and oceanographic change in the decline of North Sea black‐legged kittiwakes
TL;DR: This study shows that adequate monitoring of the effect of a fishery or of environmental change on seabird populations needs to include survival as well as breeding success.
Journal ArticleDOI
Reproductive senescence in a long-lived seabird: rates of decline in late-life performance are associated with varying costs of early reproduction.
Thomas E. Reed,Loeske E. B. Kruuk,Sarah Wanless,Morten Frederiksen,Emma J. A. Cunningham,Michael P. Harris +5 more
TL;DR: Investigation of factors influencing the rate of reproductive senescence in a long‐lived seabird, the common guillemot Uria aalge, demonstrates for the first time in a wild bird population that increased rates of senescences in reproductive performance are associated with varying costs of reproduction early in life.
Journal ArticleDOI
Scale‐dependent climate signals drive breeding phenology of three seabird species
TL;DR: This work tested the hypothesis that regulation of breeding onset should reflect the scale at which organisms perceive their environment by comparing phenology of three seabird species at a North Sea colony, and found correlations among climate patterns at different scales are likely to change in the future.
