Flowering plants are all around us and are phenomenally successful"”but how did they get to be so successful and where did they come from? This question bothered Darwin and others and a paper published in the September issue of the Botanical Journal of the Linnean Society indicates that their ability to adapt anatomically may be the answer. Sherwin Carlquist, a research botanist at the Santa Barbara Botanic Garden and recipient of the Linnean Medal for Botany, has spent his career...

Like most invasive plants introduced to the U.S. from Europe and other places, garlic mustard first found it easy to dominate the natives. A new study indicates that eventually, however, its primary weapon "“ a fungus-killing toxin injected into the soil "“ becomes less potent.The study, in Proceedings of the National Academy of Sciences, is one of the first to show that evolutionary forces can alter the very attributes that give an invasive plant its advantage. In fact, the study...

New algorithm explores future changes in plant populationsThe ability to envisage the future may be closer than you would think. A recent paper by Sean Hammond and Karl Niklas in the August 2009 issue of the American Journal of Botany (available here) presents an algorithm that may be used to predict the future dynamics of plant communities, an increasingly interesting area of study as significant environmental changes, such as global climate change and invasive species, are affecting current...

Scientists have worked out how some species of desert cactus manage to grow on nothing but bare rock, BBC News reported. They say the plants have evolved a symbiotic relationship with rock-dissolving bacteria, which they allow to grow in their roots. The cacti even pass this on to future generations. Dr. Yoav Bashan, a biologist at the Northwestern Center for Biological Research in La Paz, Mexico, said they were working in the desert when they observed that many individual cacti grew on sheer...

A newly discovered signaling pathway ensures that plants remember to flower -- even without positive signals from the environmentWhy do some plants blossom even when days are short and gray? Scientists at the Max Planck Institute for Developmental Biology have found the answer to this question: An endogenous mechanism allows them to flower in the absence of external influences such as long days. A small piece of RNA, a so-called microRNA, has a central role in this process, as a decline of...

 Deep in Africa's Kalahari Desert lies the "Devil's claw," a plant that may hold the key to effective treatments for arthritis, tendonitis and other illnesses that affect millions each year. Unfortunately, years of drought have pushed the Devil's claw toward extinction, so scientists are scrambling to devise new ways to produce the valuable medicinal chemicals of the Devil's claw and other rare plants.One group of scientists reported a major advance toward that goal here today at the...

Walking outdoors in the fall, the splendidly colorful leaves adorning the trees are a delight to the eye. In Europe these autumn leaves are mostly yellow, while the United States and East Asia boast lustrous red foliage. But why is it that there are such differences in autumnal hues around the world? A new theory provided by Prof. Simcha Lev-Yadun of the Department of Science Education- Biology at the University of Haifa-Oranim and Prof. Jarmo Holopainen of the University of Kuopio in Finland...

Pet owners have heard the warnings to keep certain poisonous houseplants away from their pets, such as Dieffenbachia (dumbcane), Philodendron, peace lily, and pothos. For houseplants like these and others, the problem may not just be a poison, but the presence of tiny crystals throughout the plant.A discussion of plants may not bring to mind crystals; however, crystals are found in hundreds of plant families. Despite this, their purpose is not well-understood. Hypotheses include acting as a...

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 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...
