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...

Tracking Movement Of Sugar In Plants
2014-04-09 12:22:18

By Karen McNulty Walsh, Brookhaven National Laboratory A new study published in the Proceedings of the National Academy of Sciences by scientists at the University of Queensland, Australia, overturns a long-held theory in plant science. Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory who are co-authors on this paper conducted critical radiotracer studies that support the new theory that plant sugars play a dominant role in regulating branching at...

Photos And Lab Analysis Needed For Leaf Study
2014-01-23 15:27:34

Brown University Automated remote photography is a convenient, labor-saving research tool for tracking leaf function and doing forest research. But does photography mirror what's actually happening on the ground? A new study finds photography accurately tracks the timing of red pigments in the fall, but the timing of green in the spring and summer — not so much. Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be...

UCLA Biologists Uncover The Secrets Involved In Leaf Size, Shape
2013-10-31 14:36:02

Alan McStravick for redOrbit.com - Your Universe Online Trees, and more specifically, the leaves that adorn them, having predated human's foray into scientific learning, should harbor no mysteries at this point. However, nature continues to surprise us. Whether it is news of gold in eucalyptus leaves, as we learned last week with news out of Australia, or the simple yet profound truth of the math that governs internal leaf structure, human understanding continues to expand with the...

Beetles In Central And South America Show Signs Of Maternal Instincts
2013-09-26 11:15:45

Pensoft Publishers Hidden in the thick foliage of tropical forests a subfamily of colorful beetles hides the secrets of the earliest stages of social behavior, showing explicit signs of maternal instincts and care. An international team of scientists from the Smithsonian Tropical Research Institute, Centro Universitário de Lavras, Staatliches Museum für Naturkunde Karlsruhe, and Université libre de Bruxelles looked into the complex subsocial behaviors present in the extraordinary...

Genetic And Hormonal Signals Responsible For Shape, Function Of Leaves
2013-05-01 09:48:37

Brett Smith for redOrbit.com - Your Universe Online As the spring flowers (finally) begin to bloom across the United States, take a closer look and you may find a whole host of genetic and hormonal signaling that is responsible for the shape and function of various aspects of the leaves of plants. In the latest edition of the open access journal PLoS Biology, a group of UK biologists has detailed new insights into the differences and similarities between flowering plants´ petal and...

How Some Leaves Get Fat: It's In Their Veins
2013-04-11 15:35:43

Brown University A "garden variety" leaf is a broad, flat structure, but if the garden happens to be somewhere arid, it probably includes succulent plants with plump leaves full of precious water. Fat leaves did not emerge in the plant world easily. A new Brown University study published in Current Biology reports that to sustain efficient photosynthesis, they required the evolution of a fundamental remodeling of leaf vein structure: the addition of a third dimension. Leaves, after all,...

Using Kidney Bean Leaves As A Roach Motel For Bedbugs
2013-04-10 07:25:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Bedbug infestations have been on the rise in recent years, and a remedy of yore may just be the answer to controlling a large problem from such a little pest, especially since the critters are becoming increasingly resilient against pesticide control. Researchers from the University of California, Irvine and the University of Kentucky (UKY) have rediscovered a type of plant that can be used as a bedbug trap, effectively stopping...

The Coco (Fagara coco or Zanthoxylum coco) is a species of evergreen tree native to Argentina and Bolivia. It grows in wild, mostly hilly, spinniferous (thorny or spiny) forests. Its habitat is found along the hilly forest of the Sierra Pampeana. This plant is found either in small isolated groups or standing alone. Other common names for this plant are cochucho or "smelly sauco". The Coco is a medium sized tree ranging from 20 to 26.25 feet tall. Its foliage is abundant and has paired...
