Flowering plants, new teeth and no dinosaurs: New study sheds light on the rise of mammals
A new study published April 30 in the Proceedings of the National Academy of Sciences identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems.

When coyote parents get used to humans, their offspring become bolder, too
When coyote parents are habituated to humans, their offspring are more habituated, too — potentially leading to negative interactions between coyotes and humans.

Assessing riverside corridors — the ‘escape routes’ for animals under climate change — in the Northwest
A study led by the University of Washington pinpoints which riverside routes in Washington, Oregon, Idaho and western Montana will be the most important for animals trying to navigate a changing climate.

Common allergen, ragweed, will shift northward under climate change
The first study of common ragweed’s future U.S. distribution finds the top allergen will expand its range northward as the climate warms, reaching new parts of upstate New York, Vermont, New Hampshire and Maine, while retreating from current hot spots.

California plain shows surprising winners and losers from prolonged drought
Meticulously tracking of 423 species before, during and after the worst droughts to hit California in more than a thousand years shows surprising patterns. Key prey species plummeted in the third year of the drought, and carnivores were hardest hit in later years.

With climate change, Mount Rainier floral communities could ‘reassemble’ with new species relationships, interactions
An unseasonably warm, dry summer on Mount Rainier in 2015 caused subalpine wildflowers to change their bloom times and form ‘reassembled’ communities, with unknown consequences for species interactions among wildflowers, pollinators and other animals.

In times of plenty, penguin parents keep feeding their grown offspring
A research team led by University of Washington biology professor Dee Boersma reports that fully grown Galapagos penguins who have fledged — or left the nest — continue to beg their parents for food. And sometimes, probably when the bounty of the sea is plentiful, parents oblige and feed their adult offspring.

Scientists crack secrets of the monarch butterfly’s internal compass
Each fall, monarch butterflies across Canada and the United States turn their orange, black and white-mottled wings toward the Rio Grande and migrate over 2,000 miles to the relative warmth of central Mexico. This journey, repeated instinctively by generations of monarchs, continues even as monarch numbers have plummeted due to loss of their sole larval food…

Fearless birds and shrinking salmon: Is urbanization pushing Earth’s evolution to a tipping point?
We’ve long known that humans and our cities affect the ecosystem and even drive some evolutionary change. What’s new is that these evolutionary changes are happening more quickly than previously thought, and have potential impacts not in the distant future — but now.

Forest fires and fireside chats: UW students learn about management challenges
An intensive two week field course helped 20 University of Washington students learn firsthand about the challenges of managing dry, fire-prone forests of the Pacific Northwest.
