Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of... view more... (2003-08-13)
Invasive plants prefer disturbance in exotic regions over home regions
One of the most invasive exotics in the western United States, the yellow starthistle, is successful both at "invasion" in non-native areas and "colonization" in native ones. view more (2006-07-27)
Ecological replacement of native red squirrels by invasive greys driven by disease
The traditional explanation for the replacement of the native red squirrel by the introduced grey over much of the United Kingdom is that the grey out-competes the red for food resources. A new study published in the March issue of Ecology Letters demonstrates that a virus introduced with the grey may also be a crucial component. The research team... view more... (2003-03-11)
A new language barrier — Why learning a new language may make you forget your old one
Traveling abroad presents an ideal opportunity to master a foreign language. While the immersion process facilitates communication in a diverse world, people are often surprised to find they have difficulty returning to their native language. view more (2007-01-19)
Who influences purchases of native plants?
Native plants are a growing niche market in the southeastern United States. Researchers have documented recent trends toward increased interest in native plants by landscape architects, wholesale and retail nursery owners, and home gardeners. view more (2009-03-26)
Researchers posit new ideas about human migration from Asia to Americas
Questions about human migration from Asia to the Americas have perplexed anthropologists for decades, but as scenarios about the peopling of the New World come and go, the big questions have remained. view more (2007-10-26)
Size of fat cells and waist size predict type 2 diabetes in women
When it comes to assessing risk for type 2 diabetes, not only do waistlines matter to women, but so does the size of their fat cells. view more (2009-09-11)
Increase seen in pneumococcal infections not covered by childhood vaccine
Alaska Native children are experiencing increased rates of serious infections caused by strains of pneumococcal bacteria that are not covered by the current childhood pneumococcal vaccine, indicating the importance of ongoing surveillance of vaccine effectiveness. view more (2007-04-25)
Gene study supports single main migration across Bering Strait
Did a relatively small number of people from Siberia who trekked across a Bering Strait land bridge some 12,000 years ago give rise to the native peoples of North and South America? view more (2007-11-27)
Ancient Connection: Evidence from Summer Digs Points to Shawnee Lookout as Oldest Continuously Occupied Site
The discoveries continue to surprise for a team of UC students digging in Shawnee Lookout Park, with a major new mound being located and a rare kiln used to fire pottery excavated in recent weeks, along with even more evidence emerging to support the theory that the site could be the largest continuously occupied hilltop Native American site in... view more...

Native fruits bear sweet antioxidants
Twelve native Australian fruits that are exceptional sources of antioxidants have been identified in research published in the journal Innovative Food Science & Emerging Technologies. view more (2007-08-03)
Attack of the invasive garden ants
An ant that is native to Eurasia is threatening to become the latest in a procession of species to invade Europe, as a result of inadvertent human introduction. Research published in the online open access journal BMC Biology demonstrates that the invasive garden ant, Lasius neglectus, which is a threat to native species, may already be more... view more...

Queen's marine biologist investigates aliens beneath the waves
Queen's University Belfast is appealing for help from the public in looking at ways to detect and stop the spread of marine aliens. view more (2008-06-17)
Native Americans Descended From a Single Ancestral Group, DNA Study Confirms
For two decades, researchers have been using a growing volume of genetic data to debate whether ancestors of Native Americans emigrated to the New World in one wave or successive waves, or from one ancestral Asian population or a number of different populations. view more (2009-04-29)
Limited climate tracking in European trees despite 10,000 years of postglacial warmth
The relative roles of environment and history as controls of large-scale species distributions is a crucial issue in biogeography and macroecology. In the forthcoming issue of Ecology Letters Svenning & Skov use bioclimatic modelling to show that among 55 native European tree species, 36 occupy less than 50% of their climatically suitable... view more...

Inherited cancer mutation is widespread in America
A gene mutation responsible for the most common form of inherited colon cancer is older and more common than formerly believed, according to a recent study. view more (2008-04-18)
Prehistoric Decline of Freshwater Mussels Tied to Rise in Maize Cultivation
USDA Forest Service (FS) research suggests that a decline in the abundance of freshwater mussels about 1000 years ago may have been caused by the large-scale cultivation of maize by Native Americans. view more (2005-06-08)
Low-income Native American women suffer high rates of domestic abuse
Low-income Native American women are at least twice as likely to suffer physical or sexual assault at the hand of their partner than the average American woman, according to an article published this week in BMC Medicine. This risk is greatly increased if the women live in very poor socioeconomic conditions. Researchers from the University of New... view more... (2004-05-19)
Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the... view more...

Bison can thrive again, study says
Bison can repopulate large areas from Alaska to Mexico over the next 100 years provided a series of conservation and restoration measures are taken, according to continental assessment of this iconic species by the Wildlife Conservation Society and other groups. view more (2008-04-30)
