Changes in Tree Phenology: an Indicator of Spring Warming in Ireland?

Recent climate warming has been observed at the global scale, but by examining developmental stages of plant species (phenology) that are dependent on local climatic conditions, climate change at the local scale can be detected. There are four gardens in Ireland belonging to the International Phenological Gardens (IPG) network, which has recorded tree phenology for more than 30 years using a co...

Differentiated Responses of Apple Tree Floral Phenology to Global Warming in Contrasting Climatic Regions

The responses of flowering phenology to temperature increases in temperate fruit trees have rarely been investigated in contrasting climatic regions. This is an appropriate framework for highlighting varying responses to diverse warming contexts, which would potentially combine chill accumulation (CA) declines and heat accumulation (HA) increases. To examine this issue, a data set was constitut...

Spring phenology was not consistently related to winter warming on the Tibetan Plateau.

Forecasting phenology under global warming.

As a consequence of warming temperatures around the world, spring and autumn phenologies have been shifting, with corresponding changes in the length of the growing season. Our understanding of the spatial and interspecific variation of these changes, however, is limited. Not all species are responding similarly, and there is significant spatial variation in responses even within species. This ...
