Article Synopsis
- - Species rely on environmental cues, like degree-days, to time their phenological events and exhibit varying responses based on their location and the season.
- - The study analyzed data from 91 taxa across 472 sites in the former Soviet Union, finding that spring phenological events advance more consistently with temperature cues (cogradient variation), while autumn events are less responsive (countergradient variation).
- - Despite some local adaptations, phenological events generally do not keep pace with environmental cues, particularly lagging further in earlier years, suggesting differing impacts of climate change on spring and autumn species responses.

View Article and Find Full Text PDFWe present an extensive, large-scale, long-term and multitaxon database on phenological and climatic variation, involving 506,186 observation dates acquired in 471 localities in Russian Federation, Ukraine, Uzbekistan, Belarus and Kyrgyzstan. The data cover the period 1890-2018, with 96% of the data being from 1960 onwards. The database is rich in plants, birds and climatic events, but also includes insects, amphibians, reptiles and fungi.

Changes in the shape or configuration of long podomeres during eclosion have been overlooked because they occur rapidly (in a few minutes) and the legs are hidden inside a tight opaque confinement: the puparium in the Cyclorrhapha, the obtect pupa in mosquitoes. We fixed insects at different times during eclosion and obtained a temporal description of changes in leg shape.
