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: It is concluded that anthropogenic climate change is having a significant impact on physical and biological systems globally and in some continents.

TL;DR: The results reveal that increased winter temperatures might impact forest ecosystems more than formerly assumed and indicate that temperature requirements and successional strategy are linked, with climax species having higher chilling and forcing requirements than pioneer species.

TL;DR: An increasing trend in the yearly amount of airborne pollen for many taxa in Europe is revealed, which is more pronounced in urban than semi-rural/rural areas, and it is suggested the anthropogenic rise of atmospheric CO levels may be influential.

TL;DR: This analysis of phenological seasons in Germany of more than four decades has several major advantages: a wide and dense geographical coverage of data from the phenological network of the German Weather Service, and the 16 phenophases analysed cover the whole annual cycle and give a direct estimate of the length of the growing season for four deciduous tree species.
