Biological invasions can begin with just 1 insect
A new study by York University biologists Amro Zayed and Laurence Packer has shown that a lone insect can initiate a biological invasion.   view more (2007-09-12)

Organic nitrogen gives new clue to biodiversity
Scientists have found that organic nitrogen is more important for plant growth than previously thought and could contribute to maintaining diversity in grasslands.   view more (2006-04-12)

Bee species outnumber mammals and birds combined
Scientists have discovered that there are more bee species than previously thought. In the first global accounting of bee species in over a hundred years, John S. Ascher, a research scientist in the Division of Invertebrate Zoology at the American Museum of Natural History, compiled online species pages and distribution maps for more than 19,200... view more...

2006 is banner year for discoveries of new species in Borneo's rainforests
Scientists have discovered at least 52 new species of animals and plants this past year on the island of Borneo. The discoveries, described in a new WWF report, include 30 unique fish species, two tree frog species, 16 ginger species, three tree species and one large-leafed plant species.   view more (2006-12-19)

What determines the speed at which birds fly?
Aerodynamic scaling rules that explain how flight varies according to weight and wing loading have been used to compare general speeds of a wide range of flyers, from the smallest insects to the largest aircraft.   view more (2007-07-17)

Lack of funding for world crop diversity threatens sustainable food supply
Researchers from the Department of Agricultural Sciences at Imperial College have warned that a large proportion of the world's collection of crop diversity could be lost due to a lack of funding for the "genebanks" in which they are stored. In a report launched today at the United Nations World Summit on Sustainable Development,... view more... (2002-08-28)

Microbes, by latitudes and altitudes, shed new light on life's diversity
Microbial biologists, including the University of Oregon's Jessica L. Green, may not have Jimmy Buffett's music from 1977 in mind, but they are changing attitudes about evolutionary diversity on Earth, from oceanic latitudes to mountainous altitudes.   view more (2008-08-12)

New golden frog discovered in remote region of Colombia
A new poisonous frog was recently discovered in a remote mountainous region in Colombia by a team of young scientists supported by the Conservation Leadership Programme (CLP).   view more (2007-08-29)

Wildlife variety is the spice of life, say scientists
Strictly embargoed for release 19:00 BST / 14:00 EST Wednesday 4 July 2001 Biodiversity is more than just a pretty face - it has an important role in the workings of the living world say results published in Nature today by scientists in the UK and France. They find that the specialisation of different plant species to different roles... view more... (2001-07-02)

Do we need a paradigm change? Disputing coevolution in herbivorous insects
Coleoptera (beetles) are one of the most successful groups of organisms on Earth. Their success in evolutionary terms is recognised by their extreme adaptive diversity (occupying almost every possible ecological niche) and their longevity (fossils from the Palaeozoic, 280 million years ago).   view more (2007-04-11)

Study of islands reveals surprising extinction results
It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands.   view more (2008-08-27)

Scientists discover interplay between genes and viruses in tiny ocean plankton
New evidence from open-sea experiments shows there's a constant shuffling of genetic material going on among the ocean's tiny plankton. It happens via ocean-dwelling viruses, scientists report this week in the journal Science.   view more (2006-03-27)

New Collection Of Bacteria
In recent times, efforts in protecting plants from insect pests are aimed at reducing the use of chemical controls, i.e., pesticides, and employing biological methods. The latter, as distinct from the chemical ones, do not contaminate the environment and agricultural products, do not accumulate in soil and water, and do not poison warm-blooded... view more...

A possible ancient origin for tuberculoses in Casablanca
Each year tuberculosis kills about three million people in the world. In particular it is responsible for the death of more than one-third of HIV- infected people, who prove particularly susceptible owing to a decline in immune defences. The agent responsible is a bacterium of the species Mycobacterium tuberculosis, also termed Koch's bacillus,... view more... (2004-11-23)

Jungle yeast
A new species of yeast has been discovered deep in the Amazon jungle. In a paper published on-line in FEMS Yeast Research, IFR scientists and colleagues from Pontificia Universidad Católica del Ecuador describe the novel characteristics of Candida carvajalis sp. nov.   view more (2009-05-21)

Researchers predict infinite genomes
Ever since the genomics revolution took off, scientists have been busily deciphering vast numbers of genomes. Cataloging. Analyzing. Comparing. Public databases hold 239 complete bacterial genomes alone.   view more (2005-09-23)

Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined.   view more (2006-05-16)

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)

Researchers go underground to reveal 850 new species
Australian researchers have discovered a huge number of new species of invertebrate animals living in underground water, caves and "micro-caverns" amid the harsh conditions of the Australian outback.   view more (2009-09-28)

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species
Writing this week in the Proceedings of the National Academy of Sciences, scientists say higher temperatures near the equator speed up the metabolisms of the inhabitants, fueling genetic changes that actually lead to the creation of new species.   view more (2006-06-01)
