Climate changes desynchronizing biological cycles in Britain http://apocadocs.com/s.pl?1265911996
The analysis confirms that spring and summer are occurring earlier, but also shows that this trend appears to be accelerating. The shift could pose problems for animals, birds and fish that rely on springtime flowering of plants to supply food for their young.... The new study compiled 25,000 records of springtime trends for 726 species of plants, animals, plankton, insects, amphibians, birds and fish across land, sea and freshwater habitats. It analysed them for changes in the timing of lifecycle events, such as egg laying, first flights and flowering, a science known as phenology.
The results showed that more than 80 percent of trends between 1976 and 2005 indicated earlier seasonal events. On average, the study showed the seasonal timing of reproduction and population growth shifted forward by eleven days over the period, and that the change has accelerated recently.
