How fires are changing the tundra’s face

Climate change takes a heavy toll on the tundra, increasing the probability of extreme droughts. As a result, the frequency of fires in forests, bogs and even wetlands continues to rise. In addition, the northern areas of the tundra have also become more accessible and negatively impacted by human activities in recent years.

The honey bee gut is colonized by specialized bacteria that help digest components of the floral pollen diet and produce molecules that likely promote bee health. Researchers have now uncovered which bacterial species perform which specific digestive functions in the bee gut.

Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta.

A new study has revealed that an extinct group of marine reptiles called sauropterygians evolved similar inner ear proportions to those of some modern day aquatic reptiles and mammals.

For many Californians, last year’s wet winter triggered a case of whiplash. After five years of drought, rain from October 2016 to February 2017 broke more than a century of records. In San Francisco Bay, biologists discovered a hidden side effect: All that freshwater rain can turn the tables on some of the bay’s invasive species.
