Atmospheric measurements show that deforestation and rapid local warming have reduced or eliminated the capacity of the eastern Amazonian forest to absorb carbon dioxide — with worrying implications for future global warming.

Seventy-five percent of arthropod-borne human disease in the U.S. is spread by ticks, and cases doubled in the U.S. between 2004 and 2016. With such significant rates of infection, information on the ranges of ticks that spread disease is essential. Read about how citizen scientists are improving the information about tick ranges.
The introduction to a new book-length report from the US Forest Service, Invasive Species in Forests and Rangelands of the United States: A Comprehensive Science Synthesis for the United States Forest Sector, starts off with this paragraph:
"Invasive species are a historical, long-term, and continually growing threat to the ecology, economy, and infrastructure of the United States. Widely recognized as one of the most serious threats to the health, sustainability, and productivity of native ecosystems, invasive species issues have commonly been viewed as problems specific to Federal, State, and private landowners. However, it is increasingly apparent that the impacts from these species are all encompassing, affecting ecosystem processes in addition to the economics of land management, public and private infrastructure, the energy sector, international trade, cultural practices, and many other sectors in the United States."
Notice on the map below, that our region of Virginia has a high rate of invasives, 38 to 80 percent!

Roads can be barriers to wildlife of all sorts. But much less is known about the impact of roads on pollinating insects such as bees and to what extent these structures disrupt insect pollination, which is essential to reproduction in many plant species. Read what the researchers found.
Wasps are valuable for ecosystems, economy and human health(just like bees). Read about their role here and here.
Researchers are playing a key role in guiding conservation efforts to protect a declining butterfly population. The eastern monarch butterfly, an important pollinating species known for its distinct yellow-orange and black color, is diminishing due to the loss of the milkweed plant--its primary food source.

A count of the Western Monarch butterfly population last winter saw a staggering drop in numbers, but there are hopeful signs the beautiful pollinators are adapting to a changing climate and ecology.

Pioneering research reveals gardens are secret powerhouse for pollinators. Home gardens are by far the biggest source of food for pollinating insects, including bees and wasps, in cities and towns, according to new research.
