Longest coral reef survey to date reveals major changes in Australia's Great Barrier Reef

An in-depth look at Australia's Great Barrier Reef over the past 91 years concludes that since 1928 intertidal communities have experienced major phase-shifts as a result of local and global environmental change, leaving few signs that reefs will return to their initial state in the near future. The long-term implications of these changes highlight the importance of avoiding phase shifts in coral reefs which may take many decades to repair, if at all.

Scientists connected fragments of pine savanna and new species keep showing up

By connecting small, restored patches of savanna to one another via habitat corridors at an experimental landscape within the Savannah River Site in South Carolina, a nearly 20-year-long study has shown an annual increase in the number of plant species within fragments over time, and a drop in the number of species disappearing from them entirely.

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.
