April Flowers for redOrbit.com - Your Universe Online More than a hundred years of growth data on individual plants has been digitized by a team of researchers at the University of Arizona´s Tumamoc Hill. The team has made this data available for study by people around the globe. New insights into the behavior of ecosystems can be developed by knowing how plants respond to changing conditions over many decades. Tumamoc Hill´s permanent research plots represent the...

NSF-supported researchers study the germination of plants in the Sonoran Desert to determine the impact of the later arrival of winter rains Global warming is a hot topic, and it's causing concern for scientists studying winter annuals in the Sonoran Desert. While desert winters have become warmer and drier over the years, climate changes have pushed the arrival of winter rains later in the year, forcing winter annual plants like the curvenut combseed (Pectocarya recurvata) to emerge later...

Global warming is giving a boost to Sonoran Desert plants that have an edge during cold weather, according to new research. Although the overall numbers of winter annuals have declined since 1982, species that germinate and grow better at low temperatures are becoming more common. "It's an unexpected result -- that global warming has led to an increase in cold-adapted species," said lead author Sarah Kimball, a research associate at the University of Arizona in Tucson. "Because the winter...
