Lyme disease is among the most common vector-borne illnesses in North America, Europe, and some parts of Asia. A spirochete bacterium called Borrelia burgdorferi causes the disease, and blacklegged ticks are responsible for the majority of North American transmissions. In a new paper, researchers present a mathematical model of Lyme disease that incorporates seasonality and […]

But a recent article suggests that flowers visited almost exclusively by hummingbirds are designed not to lure birds, but to confuse bumblebees and cost them precious time. This extra cost leads most bees to seek […]
Knowing where migrating birds came from and where they're headed is essential for their conservation and management. A new study tackles this challenge using stable isotope ratios, which reflect where birds were living while growing their feathers, and reveals that the northern reaches of Canada may have underappreciated importance for North America's waterfowl.
