A modest moss gives insight into global carbon cycling The diversity of life that can be seen in environments ranging from the rainforests of the Amazon to the spring blooms of the Mohave Desert is awe-inspiring. But this diversity would not be possible if the ancestors of modern plants had just stayed in the water with their green algal cousins. Moving onto dry land required major lifestyle changes to adapt to this new "hostile" environment, and in turn helped change global climate and...

Charles Darwin described the Venus Flytrap as 'one of the most wonderful plants in the world.' It's also one of the fastest as many an unfortunate insect taking a stroll across a leaf has discovered. But what powers this speed? Dr Andrej Pavlovič of Comenius University, Slovakia, has been studying the plants with the help of some specialised equipment and a few unlucky insects. In the wild the Venus Flytrap grows in the bogs and savannahs of North and South...

A University of Alberta research team has discovered that a plant's strategy to capture nutrients in the soil is the result of integration of different types of information. U of A ecologist J.C. Cahill says the plant's strategy mirrors the daily risk-versus-reward dilemmas that animals experience in their quest for food. Biologists established long ago that an animal uses information about both the location of a food supply and potential competitors to determine an optimal foraging strategy....

The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non"“flowering varieties would result in an 80 percent decrease in the area covered by ever"“wet rainforest. The simulations demonstrate the importance of flowering"“plant physiology to climate regulation in...

Money may not grow on trees, but gasoline, computers, and tennis shoes just might thanks to new biotech advances that could allow manufacturers to produce fuel, plastics, and other chemicals from plants instead of petroleum. That's the topic of an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Senior Business Editor Melody Voith notes that today's plant-based fuels and plastics involve growing crops and then using physical and...

LOS ANGELES, June 8 /PRNewswire/ -- Allergy season is bad for all allergy sufferers, but for pets, whose fur actually attracts pollen and dust, seasonal allergies can cause itching and be particularly miserable. Immunotherapy is the only treatment that targets the airborne allergens, like pollen and dust mites, that most often cause allergies in pets. Now board-certified veterinary dermatologist Jon Plant, DVM, DACVD, has introduced RESPIT(TM) (http://www.vetrespit.com), immunotherapy...

Scientists have for the first time determined the complete genome sequence of a brown alga and opened a new door to the understanding of multicellularity and photosynthesis. With the world's first complete sequencing of a brown algal genome, an international research team has made a big leap towards understanding the evolution of two key prerequisites for higher life on Earth - multicellularity and photosynthesis. As the internationally renowned science magazine "Nature" reported in its...

A 95-million-year-old amber deposit uncovered in Ethiopia, the first major discovery of its kind from the African continent, is helping scientists reconstruct an ancient tropical forest and gain new insights into an ecosystem once shared by dinosaurs. The scientific team"”an international group of 20 researchers including Paul Nascimbene of the American Museum of Natural History's Division of Invertebrate Zoology"”describes the findings, which include new fungus, insects, spiders,...

Dehydrin proteins are found to be a possible key to desiccation-tolerant plants such as the resurrection fern Drought can take a serious toll on plants and animals alike. When cells are deprived of water, they shrink, collapsing in upon themselves and, without water as a medium, chemicals and enzymes inside the cells may malfunction. However, some plants, like the aptly named "resurrection fern" (Polypodium polypodioides), can survive extreme measures of water loss, even as much as 95% of...

New research confirms that early angiosperms were weedy, fast-growing Fossils and their surrounding matrix can provide insights into what our world looked like millions of years ago. Fossils of angiosperms, or flowering plants (which are the most common plants today), first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, it is thought that early angiosperms must have been weedy, fast-growing shrubs and herbs found in highly...

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...
