Plants Respond To Leaf Vibrations Caused By Chewing Caterpillars
2014-07-02 03:34:36

[ Watch The Video: Plants Respond To Leaf Vibrations Caused By Insects’ Chewing ] University of Missouri-Columbia Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more...

CHICAGO, June 19, 2014 /PRNewswire-USNewswire/ -- The Cloud Foundation and Wild Horse Freedom Federation today released BLM livestock data for Beaver County and Iron County, Utah showing that despite a chorus of demands from ranchers for the removal of wild horses from the over-grazed range; the data shows livestock outnumber wild horses 10.6:1 in these areas. "It is irresponsible and false for Iron County commissioners or anyone to claim that the wild horses in that area are having...

Grazing Animals May Protect Biodiversity In Over-Fertilized Grasslands
2014-03-11 09:34:12

April Flowers for redOrbit.com - Your Universe Online The Nutrient Network has released a new, comparative study of grasslands on six continents, to be published in an upcoming issue of Nature, that suggests it might be possible to counteract the human-made overdose of fertilizer that threatens to permanently alter the biodiversity of the world's native prairies. The key finding of this study, carried out at 40 sites globally, is simple: let grazing animals crop the excess growth of...

A study of grasslands on six continents suggests a way to counteract the human-made overdose of fertilizer that threatens to permanently reduce their biodiversity: let grazing animals crop fast growing grasses. Grazers allow sunlight to reach ground level, encouraging other plants' growth, according to the study published online March 9, 2014 in Nature. College Park, MD (PRWEB) March 10, 2014 A comparative study of grasslands on six continents suggests there may be a way to counteract...

Microcosm Of Biodiversity In New Plant Species
2014-02-10 10:21:53

Pensoft Publishers Biologists working in the Andes mountains of Ecuador have described a new plant species, a wild relative of black pepper, that is in itself a mini biodiversity hotspot. The new species, Piper kelleyi, is the sole home of an estimated 40-50 insect species, most of which are entirely dependent on this plant species for survival. This discovery is part of a larger project which focuses on the influence of plant-produced chemical compounds on biodiversity. The study was...

Extracting Plant DNA From Grasshopper Guts Improves Understanding Of Plant-insect Interactions
2014-02-06 14:12:58

[ Watch the Video: Demonstration of Grasshopper Dissection ] American Journal of Botany Grasshoppers may be small, but the damages they are causing to the US agriculture industry are anything but. Every year, they feed on crops and on rangelands needed for raising livestock, costing landowners millions of dollars. Although they pose a major threat, grasshopper populations play a positive role in cycling nutrients from decomposing plant matter back into the soil. A new method to...

Plants Develop Competitive Strategies In Extreme Desert Environments
2014-01-01 06:53:13

redOrbit Staff & Wire Reports - Your Universe Online Plants in extreme desert environments develop effective strategies to compete for the area’s limited resources, according to new research out of the University of Arizona published in the American Journal of Botany. Although deserts are often thought of as barren, inhospitable places, numerous plants and animals have adapted to this harsh environment, where they are often forced to compete with rivals for scarce resources such...

The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences and has now published over 1 million references and 420 thousand tags. Scien.net has also included the new category Frugivorous, which contains scientific information on frugivores, which are animals that eat fruits, and on habitat which is the natural environment of a specific organism to get its food supplies and dietary...

Beetles Defeat Plant Defenses With Help From Microbes
2013-09-10 11:03:44

Penn State Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack rather than that of a chewing herbivore, according to a team of Penn State researchers who found that the beetles with bacteria were healthier and grew better. "For the last couple of decades, my lab has focused on induced defenses in plants," said Gary W. Felton, professor and head of entomology. "We had some clues that oral secretions of beetles suppressed...

Cycads Evolved To Grow In Groves With Seed Dispersal By Large Frugivores
2013-08-21 06:22:43

April Flowers for redOrbit.com - Your Universe Online Before the age of dinosaurs, the ancient cycad lineage existed. Cycads also co-existed more recently with large herbivorous mammals, such as the Ice Age megafauna that only went extinct a few tens of thousands of years ago. Modern cycads have large, heavy seeds with a fleshy outer coat, suggesting they rely on large bodied fruit-eating animals to disperse their seeds. However, little evidence has been found that modern larger-bodied...
