Hydrology, the research gathers together more than 25,000 long-term phenology trends for 726 species of plants and animals.

The study of the seasons, known as phenology, is important for measuring how the weather is changing in Britain with global warming.
The timing of seasonal biological events, otherwise known as phenology, has been tracked in some places for centuries.
Scientists who study how seasons affect plant and animal life cycles -- it's called phenology -- say that on average, spring comes several days earlier now than it did a few decades ago.
Data from Envisat's Medium Resolution Imaging Spectrometer (MERIS) are being used to generate daily maps that show exactly how plants are responding to the coming season, marking a significant improvement for 'phenology'.
Add "phenology" to the search reduces the hits to a more manageable "about 4,630″.
Native solitary and bumble bee populations are plummeting as global warming affects the timing, or phenology, of plants flowering, which is now occurring about 2.3 days earlier in the season.
Marsham wrote the event down, in effect inventing a new field of study, phenology – the effects of cyclic and seasonal phenomena on plants and animals.
These changes follow the pattern found by Dr. Terry Root and colleagues published in Proceedings of the National Academy of Sciences the average shift in the behavior -- phenology -- of 130 species from 1970 to 2000 means that spring is now arriving on average 10 days earlier in the Northern Hemisphere.
