Abstract: | This study is based on 47 years of observations (1961–2007) on two common bird species, the Great Tit (Parus major) and the Collared Flycatcher (Ficedula albicollis), and a dominant tree species in their habitat, the English Oak (Quercus robur). The study took place at four research sites in the Czech Republic located in full-grown, multi-aged floodplain forests
with no forestry management. An increase in air temperature over the evaluated period clearly influenced the length of phenological
phases. The full foliage date of English Oak has advanced by 8.7 days during the past 47 years. Great Tit and Collared Flycatcher
populations have reacted to the changing climate in the same way, with first laying date and mean laying date advancing by
between 6.0 and 9.0 days. In all cases, the trends are highly significant and consistent over all sites. Despite the ongoing
shift in phenological stages toward the beginning of the year, the change does not appear to have led to mistiming in the
trophic food chain. Overall, this study shows almost identical rates of change in egg laying dates for both bird species in
all the floodplain forests studied, and these trends are coherent with those of English Oak and peak herbivorous caterpillar
activity. |
