Bird brains: Does absolute size matter?
Kabadayi, Taylor, von Bayern, and Osvath (2016, Royal Society Open Science, 3, 160104) recently showed that among birds, absolute brain size predicts performance on a motor self-control task thought to be important for cognition. However, birds performed at an equivalent level to much larger-brained primates, opening up the debate about brain size and cognition.
متن کاملNew Avian Hepadnavirus in Palaeognathous Bird, Germany
In 2015, we identified an avian hepatitis B virus associated with hepatitis in a group of captive elegant-crested tinamous (Eudromia elegans) in Germany. The full-length genome of this virus shares <76% sequence identity with other avihepadnaviruses. The virus may therefore be considered a new extant avian hepadnavirus.
متن کاملPrevalence of Avian Influenza in Live Bird Markets, Bird Gardens, and Zoos in Iran in 2015: A Cross-sectional Study
Avian Influenza (AI) H9N2 is endemic in Iran; therefore, it is necessary to estimate the disease prevalence among birds in live bird markets (LBMs) and assess the risk spread across the country. Accordingly, this study aimed to estimate the prevalence of AI subtypes in LBMs, bird gardens, and zoos during October and November 2015 in Iran and investigate the associated risk factors. Data related...
متن کاملEinsteins' role in clinical research
Scientific research is a systematic process aimed to build knowledge through a set of structured evaluations, thus generating the development of both the individual that performs research and the society in which it is developed. The objective of research is to produce knowledge, possibly applicable inside and outside researchersénvironments, and perhaps generate practical actions. Research met...
متن کاملWhy some bird brains are larger than others
How does brain size and design influence the survival chances of a species? A large brain may contribute to an individual’s success irrespective of its detailed composition. I have studied the size and shape of cerebella in birds and looked for links between the bird’s cerebellar design, brain size and behavior. My results indicate that the cerebellum in large-brained birds does not scale unifo...
