White-throated Sparrow Study Traces Social Behaviors To Specific Gene
2014-01-15 09:31:53

Emory University A unique study of the white-throated sparrow has identified a biological pathway connecting variation in the birds’ aggression and parenting behaviors in the wild to variation in their genome. The Proceedings of the National Academy of Sciences (PNAS) is publishing the results of the experiments, conducted by the lab of neuroscientist Donna Maney in Emory University’s Department of Psychology. The research, which comprised behavioral observations of the study...

Charles Darwin Observations On Island Tameness In Species Confirmed
2014-01-11 05:39:37

[ Watch the Video: Island Animals Are Tamer Than On The Mainland ] Lee Rannals for redOrbit.com - Your Universe Online Like Hawaiian vacationers, living on an island actually makes animals tamer, according to a study published in Proceedings of the Royal Society B. Charles Darwin, the founder of the theory of evolution, used the Galapagos Islands as his laboratory when studying animals. The Galapagos is where Darwin developed his ideas about natural selection and how organisms evolve...

Moonlight Can Be A Benefit For Some Prey Species
2013-10-22 17:12:37

Lee Rannals for redOrbit.com – Your Universe Online According to a new study published online recently in the Journal of Animal Ecology, not all animal species are negatively affected by moonlight. One prevailing theory in ecology is that moonlight increases predation risk, but Laura Prugh, a wildlife biologist at the University of Alaska, Fairbanks, says that is not always the case. "Ecologists have long viewed the darkness of a moonless night as a protective blanket for...

Altruism Or Manipulated Helping?
2013-08-19 09:32:30

National Institute for Mathematical and Biological Synthesis (NIMBioS) Manipulation is often thought of as morally repugnant, but it might be responsible for the evolutionary origins of some helpful or altruistic behavior, according to a new study. In evolutionary biology, manipulation occurs when an individual, the manipulator, alters the behavior of another individual in ways that is beneficial to the manipulator but may be detrimental to the manipulated individual. Manipulation not...

Meerkat Study Helps To Understand How Animals Cope With Novel Man-made Threats
2013-02-19 09:56:00

ETH Zurich In their environment, wild animals are exposed to countless threats, be they predators, diseases or natural obstacles to get over, such as gorges or rivers. In the course of evolution, they have developed specific behavioral responses to allow them to deal with these risks. In recent times, numerous man-made threats have been added to the naturally-existing ones, such as dangerous roads to cross. On the evolutionary time scale, it is excluded that the animals have evolved a...

Using simple robots to simulate genetic evolution over hundreds of generations, Swiss scientists provide quantitative proof of kin selection and shed light on one of the most enduring puzzles in biology: Why do most social animals, including humans, go out of their way to help each other? In next week's issue of the online, open access journal PLoS Biology, EPFL robotics professor Dario Floreano teams up with University of Lausanne biologist Laurent Keller to weigh in on the oft-debated...

In 1964 biologist William Hamilton introduced Inclusive Fitness Theory to predict and explain phenomena ranging from animal behavior to patterns of gene expression. With its many successes, the theory became a cornerstone for modern biology. In August, 2010, Harvard researchers challenged the theory in the prestigious journal, Nature. Now Nature has published sharp rebuttals from scores of scientists, including Edward Allen Herre and William Wcislo, staff scientists at the Smithsonian...

Work addresses limitations of kin selection, a dominant theory since the 1960s Scientists at Harvard University have sketched a new map of the "evolutionary labyrinth" species must traverse to reach eusociality, the rare but spectacularly successful social structure where individuals cooperate to raise offspring. Mathematical biologists Martin A. Nowak and Corina E. Tarnita and evolutionary biologist Edward O. Wilson present their work this week in the journal Nature. Their modeling shows...

To understand how climate change may affect species survival, we need to understand how climate influences their time-keeping.New research published in the journal Biological Reviews points to time as a major factor in determining whether a species is capable of surviving in a particular habitat.In their paper "ËœTime as an ecological constraint' (Biological Reviews, August 2009), Professor Robin Dunbar of the University of Oxford, Dr Amanda Korstjens of Bournemouth University, and...

In the animal kingdom, everything is not as it seems. Individuals of the same species can look very different from each other - what biologists term 'polymorphism.' Sometimes the number of distinct visible forms - 'exuberant polymorphisms' -- in a single animal population can reach double figures. But why?Scientists at the University of York have developed computer models that may help to explain how this level of variation arises and persists. Their research is reported in the latest issue...

Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
