• Lyme Disease Imposes Large Cost On the Northeast United States

    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 Manatees Likely to Persist For At Least 100 Years—US Geological Survey

    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.

  • Scientists Evaluate Ways to Save Hawaiian Honeycreeper

    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.

  • Turtles Die in Southern California Lake Following Drought and Fire

    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.

  • We all glow together— New study shows that three quarters of deep-sea animals make their own light

    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.

  • Tropical lowland frogs at greater risk from climate warming than high-elevation species, study shows

    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.

  • Puffins that stay close to their partner during migration have more chicks

    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?

  • Wildlife Safari Defends Its Elephant Car Wash

    During the summer at the Wildlife Safari zoo in Oregon, visitors can pay $25 to have elephants “wash” their vehicles. The elephants use their trunks as sponge holders and hoses.

  • When peaceful coexistence turns into concurrence

    To find out how rising temperatures could affect species diversity, biologists from the German Centre for Integrative Biodiversity Research (iDiv) and the Leipzig University have developed a simple experiment: they covered the bottom of different Petri dishes with litter material, then put in two species of springtails, that is, arthropods only a few millimetres in size, and then added mites feeding on springtails. Subsequently, for some of the Petri dishes they increased the ambient temperature from originally 13.5°C to 18.5°C and for some other Petri dishes to 23.5°C. In those Petri dishes, the temperatures were hence five, respectively ten degrees higher than the conditions to which the animals had been exposed to in long-term cultures over years. This created simplified miniature ecosystems under climate change conditions, in which the springtail species that peacefully coexist in the wild represented the prey, and the mites represented the predators. For two months, the researchers then observed how the interactions between the three species would develop with different temperatures.

  • Hybridization between Native and Invasive Trout is Increasing in the West

    Hybridization, or the interbreeding of species, is increasing between native and invasive trout across the northern Rocky Mountains, according to a study released Tuesday by the U.S. Geological Survey and partners.
