TL;DR: In this article, the authors used an enormous systematic phenological network data set of more than 125 000 observational series of 542 plant and 19 animal species in 21 European countries (1971-2000) and concluded that previously published results of phenological changes were not biased by reporting or publication predisposition.
Journal ArticleDOI

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
Phenological sensitivity to climate across taxa and trophic levels

TL;DR: A Climate Sensitivity Profile approach is applied to 10,003 terrestrial and aquatic phenological data sets, spatially matched to temperature and precipitation data, to quantify variation in climate sensitivity and detected systematic variation in the direction and magnitude of phenological climate sensitivity.
Journal ArticleDOI
Phenology of British butterflies and climate change
David B. Roy,Tim H. Sparks +1 more
TL;DR: It is predicted that climate warming of the order of 1 °C could advance first and peak appearance of most butterflies by 2–10 days, in the absence of confounding factors.
Journal ArticleDOI
Climate change related to egg-laying trends
TL;DR: Analysis of 20 species of UK breeding birds over a 25-year period found a long-term trend towards earlier egg-laying, and analysis of a UKCIP98 national-level climate scenario predicts that average laying dates will be even earlier for 75% of species by the year 2080.
