tree height and climate
2014-08-16 06:52:39

April Flowers for redOrbit.com - Your Universe Online Trees species range in size from the Dwarf Willow at 2.5 inches to the coastal Redwood which averages 50 feet, but can top out at over 300 feet. As the coastal Redwood shows, even within one tree species, there can be a wide range of sizes. What limits the height, even within a single species? Different theories attribute this range to the amount of photosynthetic energy allocated to new leaf production, and the ability to hoist water...

Bumblebees Able To Spot Which Flowers Offer Best Rewards
2014-08-01 03:55:22

University of Exeter Bumblebees are able to connect differences in pollen quality with floral features, like petal color, and so land only on the flowers that offer the best rewards, according to a new study by researchers at the University of Exeter. Unlike nectar, bees do not ingest pollen whilst foraging on flowers, and so until now it has been unclear whether they are able to form associative relationships between what a flower looks like and the quality of its pollen. The study...

Create a striking look in the garden with mandevillas until fall’s first frost. Tokyo, Japan (PRWEB) July 15, 2014 Suntory Flowers’ Sun Parasol mandevillas, the tropical vines with trumpet-shaped flowers, are easy to grow and ideal for a unique look. These bold flowers add high impact color to containers, patios and landscapes. Plus, the tubular flowers are also known to attract hummingbirds to the garden. Though these natural climbers are usually found growing along trellises, there...

Flower Development In 3D
2014-07-14 03:36:22

University of Vienna In close collaboration with Jürg Schönenberger and Yannick Städler from the Department of Botany and Biodiversity Research of the Faculty of Life Sciences, University of Vienna, 14 developmental stages of the flower of Arabidopsis thaliana from very early meristematic floral initiation to fully developed seeds were monitored with micro-computed tomography in 3D. From the same set of developmental stages a full metabolic profile using mass spectrometry was measured...

Exhaust Fumes Derail Dinner For Hungry Moths
2014-06-27 03:34:54

Sandra Hines, University of Washington Car and truck exhaust fumes that foul the air for humans also cause problems for pollinators. In new research on how pollinators find flowers when background odors are strong, University of Washington and University of Arizona researchers have found that both natural plant odors and human sources of pollution can conceal the scent of sought-after flowers. When the calories from one feeding of a flower gets you only 15 minutes of flight, as is...

Michigan Tech Winter takes its toll on living things. To protect themselves from the elements, bears hibernate, and trees go dormant.   Biologists have observed what happens when trees become dormant, but up to now, they haven’t understood the underlying genetic mechanisms that enable them to start growing again. A team led by molecular geneticists from Michigan Technological University has identified and characterized a gene that tells a poplar tree when winter ends and a spring...

Spring Allergies Are Hard To Avoid
2014-05-28 06:25:49

April Flowers for redOrbit.com - Your Universe Online During the spring and summer, flowering grasses turn the world into a beautiful vision of green. These same grasses also turn allergy sufferers into hermits, hiding in their houses from pollen. Doctors and other clinicians have traditionally advised allergy sufferers to be aware of the pollen concentrations during the day and to reduce their outdoor activities during this season. But is it really that easy to avoid grass pollen? A...

Forest's Ability To Capture Carbon Choked By Vines
2014-05-27 03:01:03

Smithsonian Tropical Research Institute Tropical forests are a sometimes-underappreciated asset in the battle against climate change. They cover seven percent of land surface yet hold more than 30 percent of Earth's terrestrial carbon. As abandoned agricultural land in the tropics is taken over by forests, scientists expect these new forests to mop up industrial quantities of atmospheric carbon. New research by Smithsonian scientists shows increasingly abundant vines could hamper this...

University of Pennsylvania Flowers aren't just pretty to look at, they are how plants reproduce. In agricultural plants, the timing and regulation of flower formation has economic significance, affecting a crop's yield. A new paper by researchers at the University of Pennsylvania published in the journal Science has revealed that a plant hormone once believed to promote flower formation in annual plants also plays a role in inhibiting flowers from forming. The dual role of this hormone,...

Plantable Containers Show Promise For Groundcover Production And Landscaping
2014-05-05 13:46:52

American Society for Horticultural Science Sustainable paper, bioplastic containers require less transplant time, save labor, reduce plastic Consumer demand for groundcover plants for residential and commercial landscapes is on the rise. Low-growing, low-maintenance groundcovers are favored not only for their aesthetic appeal, but also for their environmental contributions such as the ability to reduce storm water runoff and control weeds. Looking for sustainable alternatives to growing...

Cyclamen persicum is a flowering, herbaceous plant from the Myrsinaceae family. It is commonly referred to as the Persian cyclamen. C. persicum is a tuberous plant. A tuber is a modified plant structure that is enlarged to store nutrients. The flowers and leaves come from buds at the top of the tuber. Roots emerge from the sides and bottom. Wild specimens have heart-shaped leaves that grow as long as 6 inches. They are usually green in color, with a light green marbling effect on the...

Kelp Forest

Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...
