A leading pioneer in long-term multidisciplinary ecological studies, Likens examines energy flow and biogeochemical flux models in the ecosystems of forests, streams and lakes. Likens is best known for leading the team of scientists that discovered acid rain in North America, and connected fossil fuels with increasing acidity of precipitation.
Stark images show the "heartbreaking" aftermath of the Los Angeles County wildfires, which continue to burn.
The Eastern Canadian Provinces (dark green) were the focal point in Canada's mitigation plan towards minimizing acid rain in the country, and lead to the implementation of the Eastern Canada Acid Rain Program in 1985. The United States-Canada Air Quality Agreement initially prioritized the reduction of acid rain within each country. [13]
The good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
