The Pan European Phenology (PEP) project is a European infrastructure to promote and
facilitate phenological research, education, and environmental monitoring. The main objective …

… dates and their standard deviation, linear regressions of the onset dates against year including
slope of the regression, standard error of the slope and significance of the regression by F…

To investigate the impact of recent climatic changes on the plant development in Europe, this
study uses phenological data of the International Phenological Gardens for the period 1969…

Distinct changes in air temperature since the end of the 1980s have led to clear responses in
plant phenology in many parts of the world. In Germany phenological phases of the natural …

… cal Gardens (IPGs) are a special phenological network in Europe founded by F. Schnelle
and E. Volkert in 1957 (Chmielewski 1996). At present the network is coordinated by the …

… Taking into account that temperature decreases 0.65C per 100 m altitude, we found—based
on the regression coefficients for altitude—leaf unfolding for F. silvatica to advance by 3.2 d …

This study examines the relationships between atmospheric influences and grain yields as
well as yield components: crop density (ears m −2 ), number of kernels per ear and kernel …

Grain legumes produce high-quality protein for food and feed, and potentially contribute to
sustainable cropping systems, but they are grown on only 1.5% of European arable land. Low …

… However, according to the climate scenario we will have a distinct temperature increase in
January (on average up to +3.4C, Chmielewski et al. 2004a), so that the plants probably will …

… changes in crops are associated with recent climate variations (see also Chmielewski, …
would be called the ‘retrospective method’ in climate impact research (Hupfer and Chmielewski, …
