Leaf Chewing Links Insect Diversity In Tropical Forests
2014-05-05 03:53:42

By A'ndrea Elyse Messer, Penn State Observations of insects and their feeding marks on leaves in modern forests confirm indications from fossil leaf deposits that the diversity of chewing damage relates directly to diversity of the insect population that created it, according to an international team of researchers. "The direct link between richness of leaf-chewing insects and their feeding damage across host plants in two tropical forests validates the underlying assumptions of many...

Aquatic Algae Can See A Wide Spectrum Of Light
2014-05-02 03:00:50

[ Watch The Video: Algae “See” A Wide Spectrum Of Light ] Andy Fell, UC Davis Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. The study by researchers at UC Davis was published earlier this year in the journal Proceedings of the National Academy of Sciences. Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the...

Erin Weeks, Duke University Bumping sex cells with the hornworts may have done it During the age of the dinosaurs, the arrival of flowering plants as competitors could have spelled doom for the ancient fern lineage. Instead, ferns diversified and flourished under the new canopy -- using a mysterious gene that helped them adapt to low-light environments. A team led by Duke University scientists has pinpointed the curious origins of this gene and determined that it was transferred to...

For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. Gilroy and colleagues, in a March 24, 2014 paper in the Proceedings of the National Academy of Sciences, showed what long had been suspected but long had eluded scientists: that calcium is involved in rapid plant cell communication. It's a finding that has...

Photosynthesis Measurements From Space
2014-03-25 10:22:18

Carnegie Institution Plants convert energy from sunlight into chemical energy during a process called photosynthesis. This energy is passed on to humans and animals that eat the plants, and thus photosynthesis is the primary source of energy for all life on Earth. But the photosynthetic activity of various regions is changing due to human interaction with the environment, including climate change, which makes large-scale studies of photosynthetic activity of interest. New research from a...

2014-03-24 07:26:02

Lund University Researchers from Lund University and the Swedish Museum of Natural History have made a unique discovery in a well-preserved fern that lived 180 million years ago. Both undestroyed cell nuclei and individual chromosomes have been found in the plant fossil, thanks to its sudden burial in a volcanic eruption. The well-preserved fossil of a fern from the southern Swedish county of Skåne is now attracting attention in the research community. The plant lived around 180...

Grazing Animals May Protect Biodiversity In Over-Fertilized Grasslands
2014-03-11 09:34:12

April Flowers for redOrbit.com - Your Universe Online The Nutrient Network has released a new, comparative study of grasslands on six continents, to be published in an upcoming issue of Nature, that suggests it might be possible to counteract the human-made overdose of fertilizer that threatens to permanently alter the biodiversity of the world's native prairies. The key finding of this study, carried out at 40 sites globally, is simple: let grazing animals crop the excess growth of...

The evolutionary path from unicellular life to multicellularity is varied, but all lead to complex organisms In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the various ways these organisms achieved multicellularity, their conglomeration of cells operate cooperatively to consume energy, survive, and reproduce. But how did multicellularity...

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...

Dawsonia
2013-11-04 10:01:23

Dawsonia is a classification of mosses. This genus is a member of the Polytrichaceae family. Dawsonia plants are commonly known to grow taller and have thicker leaves than other common mosses. Mosses are known to grow when hydrated, however most common mosses lack cuticles and internal transport tissues. This makes it difficult for them to maintain substantial amounts of water and they typically do not grow tall. Dawsonia are an exception to this common rule. Dawsonia mosses are...

Petrified Forest National Park
2013-04-24 16:53:26

Petrified Forest National Park is located in the state of Arizona in the United States. The park holds 221,552 acres of land, of which 50,260 acres are comprised of a designated wilderness. The area was once inhabited by Native American tribes including the basket maker and pueblo peoples. The first American explorers to enter the area arrived while searching for good routes leading from east to west. This group, led by Army Lieutenant Amiel Whipple, surveyed the northern area of the...

The Whisk Fern (Psilotum nudum), is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psilotopsida (the other being Tmesipteris). The distribution of Psilotum is tropical and subtropical, in the New World, Asia, and the Pacific. The highest latitudes known are in South Carolina and southern Japan for P. nudum. In the U.S., one species is found from Florida to Texas, the other in Hawaii. They had traditionally been thought not to...
