DNA from ancient skeleton shows ties to Native Americans
An ancient skeleton found nearly 20 years ago in a river in Washington is related to Native Americans, says a DNA study that could help resolve a long-running dispute over its ancestry and custody.
Enhancing honey bee populations by increasing beneficial pollinator flowers
A group of University of Maine researchers is working to enhance native and honey bee populations by increasing beneficial pollinator flowers across Maine's landscape. This is not a new idea—what is new ...
Native American populations descend from three key migrations
Scientists have found that Native American populations from Canada to the southern tip of Chile arose from at least three migrations, with the majority descended entirely from a single group of First American ...

Delayed legacy of invasive species
A global approach to monitoring biodiversity loss
In contrast to climate change, there is no coordinated global system in place for measuring and reporting on biodiversity change or loss. An international team of biologists is now addressing this gap.
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 ...
Songbirds adapt to new urban environs thanks to rapid genetic evolution
(Phys.org)—Indiana University researchers have found evidence that a species of songbird that recently colonized an urban environment exhibits less stress and bolder behavior as compared to counterparts ...
Invading crayfish success down to appetite and disease
The North American signal crayfish could be driving the native white-clawed crayfish from British waterways, because it eats more and is much less fussy about its food than the native critter.
