Road maintenance may accidentally spread the seeds of invasice plants, according to Penn State researchers. "The road graders that are used during these operations can act like a plow, pushing seeds along the road," said Emily Rauschert, senior project associate and applied ecologist in crop and soil sciences. "They can pick up seeds of an invasive grass and spread them several orders of magnitude further than the natural dispersal." The researchers created a computer simulation based on...

FRESNO, Calif., Aug. 4, 2011 /PRNewswire/ -- As the old saying goes, good things come to those who wait. The classic expression holds true for the 2011 California fresh fig season. Late season rains caused a slight delay to the much anticipated availability of California fresh figs, but fig farmers are reporting that the main crop harvest is underway now and fresh figs grown in California will be plentiful until mid-December. (Photo:...

Nutmeg-loving toucans wearing GPS transmitters recently helped a team of scientists at the Smithsonian Tropical Research Institute in Panama address an age-old problem in plant ecology: accurately estimating seed dispersal. The tracking data revealed what scientists have long suspected: toucans are excellent seed dispersers, particularly in the morning. Also, for the first time, the data enabled researchers to create a map of the relative patterns and distances that toucans distribute the...

The researchers discovered that a rainforest vine, pollinated by bats, has evolved dish-shaped leaves with such conspicuous echoes that nectar-feeding bats can find its flowers twice as fast by echolocation. The study is published today in Science. While it is well known that the bright colours of flowers serve to attract visually-guided pollinators such as bees and birds, little research has been done to see whether plants which rely on echolocating bats for pollination and seed dispersal...

MIT researchers have created a new model that predicts maximum tree height across the U.S. According to the researchers, knowing how tall trees can grow in a region gives ecologists knowledge about the potential density of a forest and size of its tree canopy to the amount of carbon stored in woodlands and the overall health of an ecosystem. The new model takes in basic meteorological data like average annual temperature, precipitation, humidity and solar radiation.  The team said the...

By Stuart Wolpert, UCLA The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA life scientists goes a long way toward solving it. In research federally funded by the National Science Foundation, the biologists found that smaller leaves are structurally and physiologically better adapted to dry soil because of their distinct vein systems. The research will be...

New technology proves more cost-effective than traditional single-head system Greenhouse vegetable production in North America has more than doubled in the past 10 years. While heavy investments have been made in modern greenhouses, improved cultivation technologies are essential for producers to realize the high productivity potential afforded by the improved facilities. Gaining popularity in greenhouse vegetable production is a high-wire system in which cucumbers plants are trained into a...

A new smartphone application is now available that allows any budding botanist to instantly identify tree types by snapping a picture of its leaf, reports the Associated Press (AP). The free iPhone and iPad app, called Leafsnap, instantly searches a growing library of leaf images amassed by the Smithsonian Institution. Seconds after taking the photo, the program returns a likely species name, high-resolution photographs and information on the tree's flowers, fruit, seeds and bark. Users...

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...

The Lily of the Nile or Calla Lily (Zantedeschia aethiopica) is a species of plant native to southern Africa in Lesotho, South Africa, and Swaziland. It has been introduced to Western Australia where it occurs in high periodical water tables and sandy soil. Several hybrids have been established and introduced to other areas around the world. Some hybrids are more suited to cooler climates. One hybrid, Crowborough, grows better in the British Isles and the northwestern United States than it...

The Coco (Fagara coco or Zanthoxylum coco) is a species of evergreen tree native to Argentina and Bolivia. It grows in wild, mostly hilly, spinniferous (thorny or spiny) forests. Its habitat is found along the hilly forest of the Sierra Pampeana. This plant is found either in small isolated groups or standing alone. Other common names for this plant are cochucho or "smelly sauco". The Coco is a medium sized tree ranging from 20 to 26.25 feet tall. Its foliage is abundant and has paired...
