Biodiversity controls ecological 'services,' report scientists in comprehenisive analysis
Accelerating rates of species extinction pose problems for humanity, according to a comprehensive study headed by a biologist at the University of California, Santa Barbara and published in the journal Nature this week. view more (2006-10-26)
Mayo Clinic study could lead to safer pesticides
Each year millions of dollars in crops are lost to two insects notorious for devastating farms: the greenbug (Schizaphis graminum) and the English grain aphid (Sitobion avenae). view more (2006-10-13)
John Innes Scientists Scoop Gold Medal at Chelsea Flower Show
The exhibit is a "fashion show" which explains how jumping genes, virus disease infection and bizarre chimeras cause the beautiful foliage and flowers we admire in plants. The display features a collection of beautiful common and unusual plants as "models" on the fashion catwalk. view more (1999-05-25)
Chickadee, nutchatch presence in conifers increases tree growth, says CU-Boulder study
Chickadees, nuthatches and warblers foraging their way through forests have been shown to spur the growth of pine trees in the West by as much as one-third, according to a new University of Colorado at Boulder study. view more (2007-08-02)
Scientists discover how to send insects off the scent of crops
Biotechnology and Biological Sciences Research Council (BBSRC)-funded research, published this week in Chemical Communication, describes how scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food... view more... (2009-09-24)
Defeating the 'superpests'
Scientists have developed a new technique that makes pesticides more effective by removing insects' ability to exhibit resistance. view more (2005-10-10)
Grazing animals help spread plant disease
Researchers have discovered that grazing animals such as deer and rabbits are actually helping to spread plant disease - quadrupling its prevalence in some cases - and encouraging an invasion of annual grasses that threaten more than 20 million acres of native grasslands in California. view more (2008-12-30)
How social insects recognize dead nestmates
When an ant dies in an ant nest or near one, its body is quickly picked up by living ants and removed from the colony, thus limiting the risk of colony infection by pathogens from the corpse. view more (2009-05-06)
Repel the aphids and you attract the leafhoppers
Things don`t always turn out as you expect when you play with genes AN ATTEMPT to make potato plants resistant to sap-sucking insects has highlighted the unpredictability of genetic engineering. The modified plants unexpectedly turned out to be vulnerable to other kinds of insect pests, demonstrating how important it is to assess each transgenic... view more... (2002-05-29)
New genetic analysis forces re-draw of insect family tree
The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects. view more (2006-10-27)
