Researchers at McGill University and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of ...

When a nuclear disaster empties a landscape of people, nature doesn’t politely wait for instructions. It moves in. After the ...

These findings could be used to prevent plant inbreeding and promote genetic diversity in future conservation efforts.

Previous studies suggested that early human populations in the Eurasian Steppe and northern China were less connected with each other until the spread of pastoralism and metallurgy around the third ...

Plants can carry long-lasting genetic damage from past population crashes, leaving them more vulnerable to future environmental change.

A landmark global study co‑led by Dalhousie researchers offers the clearest picture yet of anxiety’s biological roots, ...

Two-thirds of the populations analysed are declining in genetic diversity but conservation efforts designed to improve environmental conditions, grow populations and introduce new individuals for ...

An autoimmune disorder that affects the thyroid gland, called autoimmune hypothyroidism (AIHT), is the most common autoimmune disease, yet it remains largely understudied. New research from scientists ...

For the first time, whole-genome analysis shows that the small Cape leopards are a genetically distinct population.
