House finches that frequent North American cities and towns are better at solving new problems than their rural counterparts. They are able to solve new problems even when humans are around, says Meghan Cook of Arizona State University in the US, lead author of a study in Springer’s journal Behavioral Ecology and Sociobiology. The study investigated how increased urbanization and human presence affects the behavior and foraging habits of wildlife, and how birds, in particular, cope.

Born in the Sargasso Sea, that Atlantic Ocean gyre east of Bermuda, baby European eels will travel 4,000 miles to the freshwater rivers of Europe. Now scientists might have answered a century-old question of how these young eels accomplish such vast oceanic migrations.

Birds sing differently in response to traffic noise, which potentially affects their ability to attract mates and defend their territory, according to research published in Bioacoustics. The study found that a species of North American flycatcher sings shorter songs at a lower range of frequencies in response to traffic noise levels. The researchers suggest traffic noise reduction, for example through road closures, is a viable option for mitigating this effect.

As people across the northeastern U.S. begin venturing back into the outdoors with the arrival of spring, they will make 1 billion fewer trips than they otherwise would have if Lyme disease didn’t exist, a new Yale study concludes.

Florida’s iconic manatee population is highly likely to endure for the next 100 years, so long as wildlife managers continue to protect the marine mammals and their habitat, a new study by the US Geological Survey and the Florida Fish and Wildlife Research Institute has found.

A new study evaluates conservation actions that could save the iconic Hawaiian Honeycreeper bird, also known as the “Iiwi,” providing land managers with guidance on how to save this important pollinator. The study demonstrates how the movement of Iiwi across the slopes of Hawaii’s volcanos in search of nectar from flowers can increase their risk of contracting disease and dying.

Almost all of the turtles living in a southern California lake died following a large fire and years of drought, according to a new U.S. Geological Survey report published in the journal Knowledge and Management of Aquatic Ecosystems.

Ever since explorer William Beebe descended into the depths in a metal sphere in the 1930s, marine biologists have been astounded by the number and diversity of glowing animals in the ocean. Yet few studies have actually documented the numbers of glowing animals at different depths. In a new study in Scientific Reports, MBARI researchers Séverine Martini and Steve Haddock show that three quarters of the animals in Monterey Bay waters between the surface and 4,000 meters deep can produce their own light.

A new study of Peruvian frogs living at a wide variety of elevations—from the Amazon floodplain to high Andes peaks—lends support to the idea that lowland amphibians are at higher risk from future climate warming.

Many long-lived birds, such as swans, albatrosses or indeed, puffins, are known for their long-lived, monogamous, ‘soulmate’ pairings. Scientists have long understood that in these species, reproductive performance is influenced by pair bond strength and longevity, with long-established pairs usually better at rearing offspring. However, in species like puffins which have to migrate to distant wintering grounds during the non-breeding season, very little is known about how mates maintain their pair-bond and behave. Do they keep in contact to maintain their relationship? Or do they go their own way and abandon their mate until the following spring?
