Early breeding season for some Arctic seabirds due global warming
The breeding season of some seabirds in Arctic regions takes place earlier as a result of the temperature rise caused by climate change, according to a new article.

Scientists uncover genetic similarities among species that use sound to navigate
Insect-eating bats navigate effortlessly in the dark and dolphins and killer whales gobble up prey in murky waters thanks in part to specific changes in a set of 18 genes involved in the development of the cochlear ganglion — a group of nerves that transmit sound from the ear to the brain, according to a new study.
Read moreAnalysis of HIV-1B in Indonesia illuminates transmission dynamics of the virus
Research into the molecular phylogeny (evolutionary history) of the HIV-1B virus in Indonesia has succeeded in illuminating the transmission period and routes for three clades (main branches of the virus). This includes a clade thought to be unique to Indonesia, as well as clades that spread from Thailand, Europe and America in the 1970s and 1980s.

Maps identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries have been published.

By rearing frogs with parents — or foster parents — of different colors, biologists discovered that behavior in response to color may be more important than genetics in the evolution of new species.
Read moreGenomes of parasitic mites harming the world's bees sequenced
Researchers sequenced the genomes of the two Varroa mite species that parasitize the honey bee. They found that each species of mite used its own distinct strategy to survive in its bee host, potentially overwhelming the bees' defenses. In addition to pointing to how scientists might vanquish these deadly intruders, the findings also shed light on how parasites and hosts evolve in response to one another.
Read moreAfrican evidence support Younger Dryas Impact Hypothesis
A team of scientists from South Africa has discovered evidence partially supporting a hypothesis that Earth was struck by a meteorite or asteroid 12,800 years ago, leading to global consequences including climate change, and contributing to the extinction of many species of large animals at the time of an episode called the Younger Dryas.
Read moreFossil fish gives new insights into evolution after end-Cretaceous mass extinction
An international research team has discovered a new and well-preserved fossil stingray with an exceptional anatomy, which greatly differs from living species. The find provides new insights into the evolution of these animals and sheds light on the recovery of marine ecosystems after the mass extinction occurred 66 million years ago.
Read moreHorse nutrition: Prebiotics may do more harm than good
Prebiotics are only able to help stabilize the intestinal flora of horses to a limited degree. Before they can reach the intestines, commercially available supplements partially break down in the animals' stomachs, which can lead to inflammation of the stomach lining.
Read moreThe hidden ark: How a grassroots initiative can help save fish from extinction
Freshwater fish are the most threatened vertebrate group, and species are disappearing faster than scientists can describe them. A new study shows that aquarium hobbyists can play an important role in freshwater fish conservation by filling in the gaps left by the scientific community and conservation organizations.
