Nondestructive Visualization Techniques Used To Image Ancient Fossils
2013-11-11 12:19:33

[ Watch the Video: Animation of Serial Transverse Section of Pinus pinea Cone ] American Journal of Botany New study integrates visualization techniques to examine 150-million-year-old plant fossils without damaging specimens By integrating high-resolution X-ray imaging (termed microCT), 3D image segmentation, and computer animation, a new study conducted by Carole Gee at the University of Bonn, Germany, demonstrates the visualization of fossils without destroying the material....

Living Stone Plant Employs New Way To Improve Underground Photosynthesis
2013-10-24 08:33:07

Public Library of Science A unique plant that lives underground uses multiple mechanisms to boost photosynthesis and offers new insights into how plants adapt to extreme conditions, according to new research published October 23 in the open-access journal PLOS ONE, by Katie Field and colleagues at the University of Sheffield and other institutions. Lithops are a type of South African "living stone," a mostly underground plant that lives in extremely dry conditions. This underground life...

Study Of Photosynthesis Clears Path To Developing New Super-crops
2013-10-17 16:32:44

How some plant species evolved super-efficient photosynthesis had been a mystery. Now, scientists have identified what steps led to that change. Around three per cent of all plants use an advanced form of photosynthesis, which allows them to capture more carbon dioxide, use less water, and grow more rapidly. Overall this makes them over 50% more efficient than plants that use the less efficient form. A new study has traced back the evolutionary paths of all the plants that use advanced...

Invasive Plant Thrives Because It Adapts Quickly To Local Climates
2013-10-17 14:25:07

University of Toronto University of Toronto research has found that purple loosestrife – an invasive species that competes with native plants for light and nutrients and can degrade habitats for wildlife – has evolved extremely rapidly, flowering about three weeks earlier as it has spread to northern Ontario. This has allowed populations of the species to thrive in the colder climate with a more than 30-fold increase in seed production. "The ability of invasive species to rapidly...

Published evidence by SDSM&T and the New York State Museum suggests modern grasses eaten by large mammals of what is now the Mojave Desert are actually 15 million years old. Rapid City, S.D. (PRWEB) October 15, 2013 A South Dakota School of Mines & Technology professor’s research published today provides evidence that modern grasses are actually 15 million years old. The article published in Palaeogeography, Palaeoclimatology, Palaeocology by Robert Feranec of the New York...

Flowering Plants Evolved 100 Million Years Earlier Than Believed

[ Watch the Video: Flowering Plants Arose In The Early Triassic ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Zurich in Switzerland have uncovered evidence suggesting flowering plants evolved 100 million years earlier than previously believed, according to new research appearing in the open-access journal Frontiers in Plant Science. Flowering plants evolved from extinct plants related to conifers, cycads, ginkgos and seed ferns, and the...

A new technique for panoramic, very-high-resolution, time-lapse photography for plant and ecosystem research Ever wonder what plants do when you're not around? How about an entire forest or grassland? Not even the most dedicated plant researcher can be continuously present to track environmental effects on plant behavior, and so numerous tools have been developed to measure and quantify these effects. Time-lapse photography has been used to study many aspects of plant behavior, but...

Special microscope used to reveal hidden aspects of plant anatomy Why don't trees "bleed" to death when they are injured? Researchers from Virginia Tech, the Georg-August University of Gottingen, Germany, and the Jackson Laboratory of Bar Harbor, Maine, have discovered how "check valves" in wood cells control sap flow and protect trees when they are injured. The study, featured on the cover of the September issue of the American Journal of Botany, used a special microscope to reveal...

Microbial organisms associated with plant roots have far-flung global influences, from plant genetics to ecosystem health We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a Special Section in the American Journal of Botany on Rhizosphere Interactions: The Root...

Ancient Ancestor Of Tulip Tree Line Identified
2013-09-12 12:42:34

Indiana University The modern-day tulip tree, state tree of Indiana as well as Kentucky and Tennessee, can trace its lineage back to the time of the dinosaurs, according to newly published research by an Indiana University paleobotanist and a Russian botanist. The tulip tree, Liriodendron tulipfera, has been considered part of the magnolia family. But David Dilcher of Indiana University Bloomington and Mikhail S. Romanov of the N.V. Tsitsin Main Botanical Garden in Moscow show that it...

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...
