Bee biodiversity barometer on Fiji

The biodiversity buzz is alive and well in Fiji, but climate change, noxious weeds and multiple human activities are making possible extinction a counter buzzword. Just as Australian researchers are finding colourful new bee species, some of them are already showing signs of exposure to environmental changes.

Scientists track frog-killing fungus to help curb its spread

With the help of advanced genetic testing and hundreds of frog skin swabs, an international team of researchers has created the most complete map to date of when and where different genetic variants of the frog-killing Batrachochytrium dendrobatidis have infected frog populations around the world. The investigation also uncovered a whole new genetic lineage of the fungus, one that appears to have originated in Asia and may be the oldest variant yet discovered.

New report deepens understanding of wind-wildlife interactions

An increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation's electricity. Scenarios developed by various groups, including U.S. Department of Energy, indicate that a four- to five-fold expansion over current levels of electricity produced by wind is needed by the year 2050 to help meet U.S. carbon emission reduction goals.

Climate change study finds that maple syrup season may come earlier

Once winter nights dip below freezing and the days warm up above freezing sap begins to flow in sugar maples marking the start of the syrup season. With climate change, daily temperatures are on the rise, which affects sap flow and sugar content. By 2100, the maple syrup season in eastern North America may be one month earlier than it was during 1950 and 2017, according to a new study.

To grow or to flower: Genes IDed in early land plant descendant also found in modern crops

Since they first arrived on land, plants have likely been using the same genetic tools to regulate whether they grow bigger or reproduce. The discovery was made using liverwort, one descendant of the first plants to move out of the ancient oceans and onto land.
