Threats to the plants include climate change and habitat loss.

The wild population of the species was declared extinct almost 40 years ago, but now researchers have found their genes in a pack of canines near the Gulf coast.

Simulations of Earth’s climate 252 million years ago reveal that the same symptoms of modern climate change likely account for the time period’s extensive loss of marine life.

Compared to 500,000 breeding pairs in the 1980s, only 60,000 penguin pairs now remain.

Thousands of scientists around the world sign a statement that warns the existence of 1,500 species will be imperiled if President Donald Trump’s wall is erected.

Researchers froze the fertilized eggs, taken from southern white rhinos, in hopes of preserving the near-extinct northern subspecies.

Assessments of species vulnerability provide crucial information for conservation efforts. But the science behind them is still evolving.

From the difficulty of tracking rare populations to the danger of poachers exploiting distribution data, the complications of studying endangered species require creative solutions from researchers.

To calculate the likelihood that organisms will be harmed by climate change, researchers estimate their exposure, sensitivity, and ability to adapt to new conditions.
