Biologists produce global map of plant biodiversity
03-20-2007 · EurekAlert!Biologists at the University of California, San Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on Earth to date.

- How global is the Global Biodiversity Information Facility?
11-09-2007 · EurekAlert!
A study, funded by the Biotechnology and Biological Sciences Research Council, and conducted by biologists at the University of Reading and computer scientists at the University of Cardiff, has revealed large gaps in data available to the Global Biodiversity Information Facility -- the world's largest single data network which gives access to millions of current digitised biodiversity records. The paper was published in the Nov. 7 issue of the online, open-access journal PLoS ONE.

- Case Western researcher, international team call for better global warming forecasting
03-30-2007 · EurekAlert!
Case Western Reserve University faculty member Matthew Sobel has joined a team of international scientists calling for better forecasting methods in predicting how climate changes will impact the earth’s plant and animal species. They have reported eight ways to improve biodiversity forecasting in the BioScience article, "Forecasting the Effects of Global Warming on Biodiversity."

- Genetic differences in clover make one type toxic
10-01-2007 · EurekAlert!
That clover necklace you make for your child could well be a ring of poison. That's because some clovers have evolved genes that help the plant produce cyanide - to protect itself against little herbivores, such as snails, slugs and voles, that eat clover. Other clover plants that do not make cyanide are found in climates with colder temperatures. Kenneth Olsen, Ph.D., Washington University biologist is looking at the genetics behind this polymorphism.

- Elevated CO2 in atmosphere weakens defenses of soybeans to herbivores
07-06-2007 · EurekAlert!
In research to be presented at the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), scientists will show that elevated CO2 may negatively impact the relationship between some plants and insects. Elevated CO2 is considered to be a serious catalyst of global change. Its effects can be felt throughout the ecosystem, including the insect-plant food chain link. Safeguarding highly-usable crops is of great importance to many local and national economies.

- Illinois-based study of energy crops finds miscanthus more productive than switchgrass
07-10-2007 · EurekAlert!
At the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), scientists will present findings on how to economically and efficiently produce plant crops suitable for sustainable bioenergy. Improving the production of such biomass is important because it should significantly ease and eventually replace dependence on petroleum-based fuels. Biomass is plant material, vegetation or agricultural waste used as fuel.

- Food safety begins as vegetables grow
06-11-2007 · EurekAlert!
Monitoring vegetables while they are growing is crucial in the prevention of contamination of fresh produce with harmful bacteria such as E. coli and Salmonella, say plant pathologists who are members of the American Phytopathological Society.

- Is biodiversity the future of farming?
02-16-2007 · EurekAlert!
If we can design complex farming systems that are less energy intensive, more resilient in unstable climates, and that begin to out-produce industrial monocultures, the economic advantages may be an incentive to change, says author Fred Kirschenmann, Leopold Center for Sustainable Agriculture, in the March-April 2007 issue of Agronomy Journal.

- The conservation lens
10-24-2007 · EurekAlert!
An interdisciplinary team of US, UK and Chilean taxonomists, ecologists and philosophers explored the world's southernmost forest and tundra ecosystems to estimate the diversity of the dominant vegetation, namely tiny bryophytes and lichens. They assess its regional and global significance in their study, "Changing lenses to assess biodiversity: patterns of species richness in sub-Antarctic plants and implications for global conservation." The work appears in the online issue of Frontiers of Ecology and the Environment.

- Global malaria map key weapon in fight against malaria, scientists say
12-04-2006 · EurekAlert!
Information on the global burden of malaria remains the subject of "best guesses," and as a result resource allocation for malaria control remains "driven by perceptions and politics, rather than an objective assessment of need," say two prominent malaria researchers in PLoS Medicine.

- Rotting leaf litter study could lead to more accurate climate models
01-18-2007 · EurekAlert!
Bags of decomposing leaf litter have allowed a research team led by scientists at UC Berkeley and Colorado State University to produce an elegantly simple set of equations to calculate the nitrogen released into the soil during decomposition, which in turn could significantly improve the accuracy of global climate change models.
