URBANA, Ill. – Imagine a tropical forest and you might conjure up tall trees hung with vines, brightly colored birds, howling monkeys, and … rain. Indeed, precipitation patterns, along with temperature, dictate where tropical forests are distributed around the world, but surprisingly, scientists know very little about the direct effects of rainfall on animals.

MORRIS, Ill. – We are never more conscious of the summer sun than while struggling to unpack a trap full of turtles, watching with resignation as the wind slowly drags us and our kayak across the marsh. We are in Goose Lake Prairie State Natural Area, about 50 miles southwest of Chicago. We visit these wetlands two weeks per month during the field season, which runs from May to October.

URBANA, Ill. ­– Bird biodiversity is rapidly declining in the U.S. The overall bird population decreased by 29% since 1970, while grassland birds declined by an alarming 53%.

Valuable for so much more than flight and song, birds hold a key place in ecosystems worldwide. When bird numbers and varieties dwindle, pest populations increase and much-needed pollination decreases. Those examples alone negatively impact food production and human health.

URBANA, Ill. – Governments might be able to prevent future pandemics by investing as little as $22 billion a year in programs to curb wildlife trafficking and stem the destruction of tropical forests, a new analysis by an international team of scientists and economists shows.

Compared to the $2.6 trillion already lost to COVID-19, and the more than 600,000 deaths the virus has caused so far, that annual investment represents an exceptional value, the experts argue.

CHAMPAIGN, Ill. — Northern bobwhites are attracted to a habitat based on whether other bobwhites are present there, researchers at the University of Illinois at Urbana-Champaign report. This phenomenon, called conspecific attraction, could aid conservation efforts.

URBANA, Ill. – When the tree fell that October in 2015, the tropical giant didn’t go down alone. Hundreds of neighboring trees went with it, opening a massive 2.5-acre gap in the Panamanian rainforest.

Treefalls happen all the time, but this one just happened to occur in the exact spot where a decades-long ecological study was in progress, giving University of Illinois researchers a rare look into tropical forest dynamics.

URBANA, Ill. – The prehistoric-looking alligator snapping turtle may be the largest freshwater turtle in North America, but that doesn’t make it easy to spot. The up-to-200-pound armored beasts have only been officially recorded in Illinois 16 times since the late 1800s. But, in a recent study, University of Illinois scientists have demonstrated an effective new method to detect the secretive reptiles in the wild.

From mid-November 2015 through February 2016, scientists used GPS transmitters to track the movements of Canada geese near Midway International Airport in Chicago. They discovered that – in the colder months, at least – some geese are hanging out on rooftops, in a rail yard and in a canal close to Midway’s runways. This behavior increases the danger of collisions between geese and airplanes, the researchers say.

CHAMPAIGN, Ill. — A new tool uses an interactive database of geographic and genetic information to help authorities quickly identify where the confiscated tusks of African elephants were originally poached.

Developed by an international team of researchers, the Loxodonta Localizer matches genetic sequences from poached ivory to those stored in the database. It relies on genetic information from a small, highly variable region of mitochondrial DNA from African elephants.

URBANA, Ill. – Invasive silver carp have been moving north toward the Great Lakes since their accidental release in the 1970s. The large filter-feeding fish, which are known to jump from the water and wallop anglers, threaten aquatic food webs as well as the $7 billion Great Lakes fishery. But, for the past decade, the invading front hasn’t moved past Kankakee. A new study, led by scientists at the University of Illinois, suggests that Chicago’s water pollution may be a contributing to this lack of upstream movement.
