Mockingbirds In Fickle Climates Sing Fancier Tunes:

Why are some birds simple singers and others vocal virtuosos? Researchers at the National Evolutionary Synthesis Center (NESCent), the Cornell Lab of Ornithology, and McGill University suspect that inconsistent climates may play a role. A large-scale study of mockingbirds in diverse habitats reveals that species in more variable climes also sing more complex tunes. “As environments become more variable or unpredictable, song displays become more elaborate,” said Carlos Botero, a postdoctoral researcher at NESCent in Durham, NC. NESCent is an NSF-funded collaborative research center operated by Duke University, the University of North Carolina at Chapel Hill, and North Carolina State University.

Opposites Attract: How Genetics Influences Humans To Choose Their Mates:

People By Nature Are Universally Optimistic, Study Shows:

– Despite calamities from economic recessions, wars and famine to a flu epidemic afflicting the Earth, a new study from the University of Kansas and Gallup indicates that humans are by nature optimistic.

Using ‘Dominance’ To Explain Dog Behavior Is Old Hat:

A new study shows how the behaviour of dogs has been misunderstood for generations: in fact using misplaced ideas about dog behaviour and training is likely to cause rather than cure unwanted behaviour. The findings challenge many of the dominance related interpretations of behaviour and training techniques suggested by current TV dog trainers. Contrary to popular belief, aggressive dogs are NOT trying to assert their dominance over their canine or human “pack”, according to research published by academics at the University of Bristol’s Department of Clinical Veterinary Sciences in the Journal of Veterinary Behavior: Clinical Applications and Research.
