Even though it was closed decades ago, the Giant Mine on the outskirts of Yellowknife has left a long environmental legacy.

A new study by Los Alamos National Laboratory scientists and colleagues confirms that increasing minimum winter temperatures allow beetles to expand their range but reveals that overcrowding can put the brakes on population growth.

University of Alberta paleontologists discovered a new species of marine lizard that lived 70 to 75 million years ago, with its muscle and skin remarkably well preserved.

Deforestation, greenhouse gas emissions, biodiversity loss, nitrogen pollution – today’s agricultural feed cultivation for cattle, pigs and chicken comes with tremendous impacts for the environment and climate. Cultivating feed in industrial facilities instead of on croplands might help to alleviate the critical implications in the agricultural food supply chain. Protein-rich microbes, produced in large-scale industrial facilities, are likely to increasingly replace traditional crop-based feed. A new study now published in the journal Environmental Science & Technology for the first time estimates the economic and environmental potential of feeding microbial protein to pigs, cattle and chicken on a global scale. The researchers find that by replacing only 2 percent of livestock feed by protein-rich microbes, more than 5 percent of agricultural greenhouse gas emissions, global cropland area and global nitrogen losses could each be decreased.

Climate change will have a rapidly increasing effect on the structure of global ecological communities over the next few decades, with amphibians and reptiles being significantly more affected than birds and mammals, a new report by UCL finds.
