Camponotini ant species have their own distinct microbiomes and the bacteria may also vary by developmental stage, according to a study published Nov. 22, 2017, in the open-access journal PLOS ONE by Manuela Oliveira Ramalho from the Universidade Estadual Paulista 'Júlio de Mesquita Filho,' Brazil, and colleagues.
A special publication titled "Planetary Biodiversity Inventory (2008-2017): Tapeworms from the Vertebrate Bowls of the Earth," just published by the University of Kansas Museum of Natural History.
The first comparison of plain water, electrolyte injections and a chicken-flavored electrolyte drink as techniques for keeping sniffer dogs hydrated when working in hot weather finds that while all are safe and effective, dogs drink more and are more hydrated when given a chicken-flavored electrolyte drink.
A mutation in a gene called SCL24A4 that causes enamel hypoplasia, or poorly formed enamel of the teeth in Samoyed dogs has been identified by researchers at the Center for Companion Animal Health, University of California, Davis. The findings are published in the open-access journal Canine Genetics and Epidemiology.
Researchers in the University of Helsinki's Canine Mind research project found that oxytocin made dogs interested in smiling human faces. It also made them see angry faces as less threatening. Associated with affection and trust, the hormone oxytocin is probably a key factor in the interaction between dogs and humans.
A team of Swedish scientists have used national registries of more than 3.4 million Swedes aged 40 to 80 to study the association between dog ownership and cardiovascular health. Their study shows that dog owners had a lower risk of death due to cardiovascular disease or to other causes during the 12-year follow-up.
By attaching miniaturized Global Positioning System tags to cave bats near a mountain ridge in Thailand, researchers have shown that bats repeatedly use mountain slopes to ascend to altitudes of more than 550 m above the ground.
Previous research has shown that animals can remember specific events, use tools and solve problems. But exactly what that means remains a matter of scientific dispute. Cameron Buckner, assistant professor of philosophy at the University of Houston, suggests the evidence shows a wide range of animal species exhibit so-called 'executive control' when it comes to making decisions, consciously considering their goals and ways to satisfy those goals before acting.
A new giraffid species from Spain may extend the range and timespan of the ancestors of giraffes, according to a study published Nov. 1, 2017 in the open access journal PLOS ONE by María Ríos from the National Museum of Natural History, Spain, and colleagues.
Young bats adopt a specific 'dialect' spoken by their own colonies, even when this dialect differs from the bat 'mother tongue,' a new study publishing Oct. 31 in the open-access journal PLOS Biology shows. By offering insight into the evolutionary origins of language acquisition skills, the study, led by Dr. Yossi Yovel of Tel Aviv University, and his students Yosef Prat and Lindsay Azoulay, calls into question the uniqueness of this skill in humans.
