Anomalously high sea surface temperatures may compromise the immune response of California sea lions, according to a study published June 28, 2017 in the open-access journal PLOS ONE by Karina Acevedo-Whitehouse from Autonomous University of Queretaro, Mexico, and colleagues.
Many geckos inhabit trees, often living high in the canopy. Relying on their incredible adhesive strength to help them break their fall, they jump from trees, and land on leaves or smooth tree trunks. A team of researchers led by a biologist at the University of California, Riverside now reports that the gecko adhesive system may reach its functional limits in extreme situations, such as when a gecko falls/jumps from the canopy of a rainforest.
On polygamous females and single-parent males Behavioral researchers at Bielefeld University are studying plovers Male plovers survive more successfully in the wild than females. Behavioral researchers at Bielefeld University have studied how sex biases develop across the life span of the plover. They report on the consequences of the surplus of males for rearing chicks in the research journal 'Proceedings of the National Academy of Sciences'.
About half of all pet owners share their beds or bedrooms with their pets. Studies about co-sleeping are limited to the bedtime arrangements of adults, or parents and their children. In an article in Springer's journal Human Nature, the authors argue that society regards both human-animal and adult-child co-sleeping with apprehension. These concerns should be set aside because both practices have their benefits, says lead author Bradley Smith of Central Queensland University in Australia.
Honeybees may not need key brain structures known as mushroom bodies in order to learn complex associations between odors and rewards, according to new research published in PLOS Computational Biology.
While more than 13,000 cases of Chikungunya viral disease were reported in Brazil in 2015, scientists had never before detected the virus in a captured mosquito in this country. Now, researchers reporting in PLOS Neglected Tropical Diseases have identified a mosquito -- caught in the Brazilian city of Aracaju -- that's naturally infected with the East-Central-South-African (ECSA) genotype of Chikungunya.
Bornaviruses cause a lethal form of encephalitis, Borna disease, among horses and sheep. To date only a few cases were reported in Austria. Recently, four horses were afflicted in the same area of Upper Austria within just two years. Tests on local shrews, the reservoir host, confirmed the suspicion of a local viral reservoir. The study in Emerging Microbes & Infections documents a rare outbreak of Borna disease in a new endemic area in Austria.
Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities. Despite these differences, however, it has been difficult to identify specific mental capacities that distinguish humans from other animals. Researchers at the City University of New York (CUNY) and Stockholm University have now discovered that humans have a much better memory to recognize and remember sequential information.
DNA found at archaeological sites reveals that the origins of our domestic cat are in the Near East and ancient Egypt. Cats were domesticated by the first farmers some 10,000 years ago. They later spread across Europe and other parts of the world via trade hub Egypt. The DNA analysis also revealed that most of these ancient cats had stripes: spotted cats were uncommon until the Middle Ages.
A survey of United States hospitals, eldercare facilities and therapy animal organizations revealed their health and safety policies for therapy animal visits varied widely, with many not following recommended guidelines for animal visitation. The research from investigators at Tufts Institute for Human-Animal Interaction at Tufts University appears online on June 19, 2017, in advance of print in the American Journal of Infection Control.
