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)
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)
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)
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)
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)
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)
National survey shows minority children experience multiple disparities in health care
There is a lack of equity in health care for minority children in America, according to data gathered in a nationwide survey and analyzed by a UT Southwestern Medical Center researcher. view more (2008-02-06)
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)
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)
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...

Invasive plant outcompeted by its native ancestors
Invasive alien species are one of the greatest threats to global biodiversity. Part of their success may be due to rapid evolutionary changes when invaders adapt to the novel conditions in their invaded habitats. Invasive plants, in particular, are believed to double-profit from a loss of their natural enemies and subsequent evolution of less... view more... (2004-03-18)
Old World Origin of New World Dogs
When humans arrived to the New World they had dogs with them. This is the conclusion reached by a study published this week in the journal Science by evolutionary biologists at the University of California, Los Angeles, and Uppsala University, Sweden, in collaboration with zooarchaeologists from Mexico and Peru. Dogs have been present in the New... view more... (2002-11-22)
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...

Academics Seek Bilingual Volunteers For Language Study
Psychologists and linguists at the University of Edinburgh are recruiting Spanish; Japanese and native English-speaking adults for a research project, which will help understand how non-native languages, are learned and stored in the memory. The research aims to identify certain pitfalls in spelling, both in native and non-native speakers, and... view more... (2002-09-03)
Over-sexed and over here - the onward march of the American crayfish
Important new evidence of the onward march of the American signal crayfish through the UK's watercourses will be announced at the British Ecological Society's Winter Meeting, being held at the University of York on 18-20 December 2002. Speaking at the meeting, environmental consultant Stephanie Peay will describe a new method that will allow much... view more... (2002-12-09)
Synthetic protein mimics structure, function of metalloprotein in nature
Scientists have designed a synthetic protein that is both a structural model and a functional model of a native protein, nitric-oxide reductase. view more (2009-12-11)
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)
Climate change opens new avenue for spread of invasive plants
Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants. view more (2008-11-20)
