Surprising Spread Of Spring Leaf-out Times: Study
2014-06-19 03:54:51

Richard Primack, Boston University Medical Center Observing 1,600 species at 8 botanical gardens globally should impact climate-change models Despite conventional wisdom among gardeners, foresters and botanists that woody plants all "leaf out" at about the same time each spring, a new study organized by a Boston University biologist found a surprisingly wide span of as much as three months in leaf-out times. Significantly, observations the past two springs of 1,597 woody plants in...

Autumn Ending Later And Spring Starting Earlier In The Northern Hemisphere
2014-03-31 11:19:49

University of Southampton A study by the University of Southampton suggests that on average the end of Autumn is taking place later in the year and Spring is starting slightly earlier. A team of researchers examined satellite imagery covering the northern hemisphere over a 25 year period (1982 - 2006), and looked for any seasonal changes in vegetation by making a measure of its ‘greenness’. They examined in detail, at daily intervals, the growth cycle of the vegetation –...

A University of Maryland professor's 39-year tally of two million wildflower blooms shows a complex series of changes due to a warmer climate, with probable ripple effects for birds, bees and other animals. (PRWEB) March 17, 2014 A unique 39-year study of wildflower blooms in a Colorado Rocky Mountain meadow shows more than two-thirds of alpine flowers have changed their blooming pattern in response to climate change. Not only are half the flowers beginning to bloom weeks earlier, but...

161-Year Study Shows Warmer World Causes Earlier Spring Flowering
2013-01-17 09:10:44

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from three universities have found that record temperatures in 2010 and 2012 resulted in the earliest spring flowering season in the eastern United States in more than 160 years. Using the phenological records of two iconic American naturalists, Henry David Thoreau and Aldo Leopold, scientists have shown that some springtime bloomers have appeared as much as a month earlier in response to the warming climate. This study...

Nature Observation Database Receives One-Millionth Entry

Key database monitoring climate change received its one-millionth report from a network of "citizen scientists" On April 30, 2012, the USA National Phenology Network (NPN), partially funded by the National Science Foundation (NSF), received its one-millionth nature observation from volunteers--many of whom are non-scientists or "citizen scientists." The observation will help understand the impacts of climate change on Earth's plants and animals. Scientists and citizen volunteers...

Image 1 - Spring Advancing Faster Than Experiments Suggest

Plants are leafing out and flowering sooner each year than predicted by results from controlled environmental warming experiments, according to data from a major new archive of historical observations assembled with the help of a NASA researcher. Researchers use experiments that manipulate the temperature of the environment surrounding small plots of plants to gauge how specific plants will react to higher temperatures. The observed plant responses can then be incorporated into models that...

The Twenty-four Solar Terms are ancient Chinese terms used for about 2000 years. They describe 24 stages or timings associated with seasonal changes in phenology and agricultural activity throughout a year. Qian et al. from the Key Laboratory of Regional Climate-Environment for East Asia, Chinese Academy of Sciences, quantitatively defined the somewhat 'astronomic' term for the first time, based on modern temperature records. This facilitated an investigation of changes in the climatic Solar...

Spring is hailed as the season of rebirth, but if it comes too early, it can threaten the plants it is meant to welcome. A University of Alberta study shows that climate change over the past 70 years has pushed some of the province's native wildflowers and trees into earlier blooming times, making them more vulnerable to damaging frosts, and ultimately, threatening reproduction. U of A PhD candidate Elisabeth Beaubien and her supervisor, professor Andreas Hamann of the Department of Renewable...

As a gradually warmer climate emerges, researchers are observing flowers blooming sooner and birds breeding earlier in the year, but is it may also be affecting the breeding habits of larger mammals. A new study of the United Kingdom's Chillingham cattle, published in the British Ecological Society's Journal of Animal Ecology, reveals climate change is upsetting the breeding habits of those cattle, specifically resulting in fewer calves surviving, The Telegraph is reporting. Examining 60...

The onset of summer in England has been advancing since the mid 1950s, research from a pair of University of Sheffield geographers has shown. The investigations, conducted by Amy Kirbyshire, a former undergraduate of the University, and Professor Grant Bigg, Head of the Department of Geography at the University, examined records of the first blooming date of early summer flowering plants (phenology) and the timing of first occurrences of warm `summer´ temperatures - events...
