Growing green roofs
One way to maximize the eco-friendly factor of a structure is to include a green roof-and this doesn't refer to the paint color. view more (2009-09-04)
Scientists demonstrate importance of niche differences in biodiversity
Scientists at UC Santa Barbara have found strong evidence that niche differences are critical to biodiversity. Their findings are published online in this week's issue of the journal Nature. view more (2009-08-13)
Global warming capable of sparking mass species extinctions
The Earth could see massive waves of species extinctions around the world if global warming continues unabated, according to a new study published in the scientific journal Conservation Biology. view more (2006-04-12)
Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week. Researchers from the Cambridge-based British Antarctic Survey (BAS) reviewed the best available data from a range of long-term studies to test the view that warming of the Earth`s climate is... view more...

Insignia -- A new way to identify viruses and bacteria
Now that the genome sequences of hundreds of bacteria and viruses are known, we can design tests that will rapidly detect the presence of these species based solely on their DNA. view more (2007-05-18)
Fossil data plug gaps in current knowledge, study shows
Researchers have shown for the first time that fossils can be used as effectively as living species in understanding the complex branching in the evolutionary tree of life. view more (2007-10-03)
Ships bring alien jellyfish invaders to our shores
Marine environments around the world are being threatened by exotic species of the moon jellyfish being dispersed by international shipping, according to new research. view more (2005-08-16)
Too much water, fertilizer bad for plant diversity
Too much of multiple good things - water or nutrients, for example - may decrease the diversity of plant life in an ecosystem while increasing the productivity of a few species, a UC Irvine scientist has discovered. view more (2007-03-27)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)
Extinct rodent species discovered
An international team of scientists has discovered an extinct rodent species, based on fossil tooth remains found in Alborache, Valencia. Eomyops noeliae, from the Eomyidae family, represents the oldest find within this genus in the world. view more (2009-07-29)
Sky islands: metaphor or misnomer?
The term "sky islands" sounds intriguing, but it may be more lyrical than useful when discussing mammal distributions, according to new research from Eric Waltari of the Sackler Institute of Comparative Genomics at the American Museum of Natural History and Robert Guralnick from the University of Colorado at Boulder. view more (2008-08-14)
Scientists warn that species extinction could reduce productivity of plants on Earth by half
An international team of scientists has published a new analysis showing that as plant species around the world go extinct, natural habitats become less productive and contain fewer total plants -- a situation that could ultimately compromise important benefits that humans get from nature. view more (2007-11-06)
Current mass extinction spurs major study of which plants to save
The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say. view more (2008-10-21)
Smithsonian scientists find evidence that could rewrite Hawaii's botanical history
Scientists at the Smithsonian Institution have discovered data that suggests one of Hawaii's most dominant plants, Metrosideros, has been a resident of the islands far longer than previously believed. view more (2008-04-16)
Ecologists say metabolism accounts for why natural selection favors only some species
Why are some species of plants and animals favored by natural selection? And why does natural selection not favor other species similarly? view more (2008-11-04)
Caribbean frog populations started with single, ancient voyage on South American raft
Nearly all of the 162 land-breeding frog species on Caribbean islands, including the coqui frogs of Puerto Rico, originated from a single frog species that arrived on a sea voyage from South America. view more (2007-06-11)
New species from old data - By searching genome sequences of several Drosophila species researchers have identified new bacterial species that live inside fruit flies.
Researchers have discovered three previously unknown species of a bacterium by scanning a publicly available data bank, reveals a study published today in the journal Genome Biology. The finding highlights the value of making unanalysed data from large-scale genome sequencing projects openly available online. view more (2005-02-18)
Enzyme may be a key to Alzheimer's-related cell death
A Purdue University researcher has discovered that the amount of an enzyme present in neurons can affect the mechanism thought to cause cell death in Alzheimer's disease patients and may have applications for other diseases such as stroke and heart attack. view more (2009-10-08)
A changing climate for protected areas
On April 6, the Intergovernmental Panel on Climate Change (IPCC) will release a report entitled Climate Change 2007: Impacts, Adaptation, and Vulnerability that focuses on how climate change is affecting the planet. view more (2007-04-03)
In spiders, size matters: Small males are more often meals
Female spiders are voracious predators and consume a wide range of prey, which sometimes includes their mates. view more (2008-09-11)
