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
April 7, 2017 09:36 AM - University of Oxford

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
April 6, 2017 09:02 AM - German Centre for Integrative Biodiversity Research (IDIV) Halle-Jena-Leipzig

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, 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.

Penn Researchers Investigate How Songbirds Teach Themselves Songs

Music can be a powerful form of expression. It’s especially important for songbirds such as zebra finches, which learn the songs of their fathers in order to court mates.
