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.

TL;DR: In this article, a multispecies estimate for Swiss Alpine spring phenology for the period 1965-2002 by applying empirical orthogonal function (EOF) analysis on a combination of 15 spring phases was investigated using a multivariate statistical model.

TL;DR: In the context of the last 300 years and based on three tree species, 2007 marks the third earliest, after 1961 and 1794, plant phenological spring onset in Switzerland as mentioned in this paper.

TL;DR: In this article, the authors studied the long term phenological trends in Switzerland and focused upon the differences between the lowland and the alpine regions (higher than 1000 m asl) for the 1951-2002 period.

TL;DR: A tendency towards earlier appearance dates in spring and later appearance date in autumn could be made out according to those from the airborne pollen monitoring network.
