Evolution Of Species Does Not Always Follow Darwin's Theories
2013-12-23 04:19:44

redOrbit Staff & Wire Reports - Your Universe Online Evolutionary scientists have long argued that species that live together must evolve in different ways in order to avoid direct competition with each other, but new research published Sunday in the journal Nature suggests otherwise. A team of researchers led by Dr. Joe Tobias of Oxford University's Department of Zoology studied ovenbirds, one of the most diverse families of birds in the world, in order to conduct an in-depth...

A recent decline in ovenbirds (Seiurus aurocapilla), a ground-nesting migratory songbird, in forests in the northern Midwest United States is being linked by scientists to a seemingly unlikely culprit: earthworms. A new survey conducted in Minnesota's Chippewa National Forest and Wisconsin's Chequamegon-Nicolet National Forest by a research team led by Scott Loss of the University of Minnesota and the Smithsonian Migratory Bird Center has revealed a direct link between the presence of...

Some birds use information gathered from eavesdropping on their enemies to find safer areas to build their nests, scientists have found. Birds that nest on the ground, such as ovenbirds and veeries, fall prey to predators as many eggs and fledglings struggle to survive. Neighboring chipmunks are a major threat. These birds use a range of cues to determine the location of their nests, but Quinn Emmering and Dr. Kenneth Schmidt from Texas Tech University suggest that the "chips," "chucks" and...

Ecologists have at last worked out a way of using recordings of birdsong to accurately measure the size of bird populations. This is the first time sound recordings from a microphone array have been translated into accurate estimates of bird species' populations. Because the new technique, reported in the British Ecological Society's Journal of Applied Ecology, will also work with whale song, it could lead to a major advance in our ability to monitor whale and dolphin numbers. Developed by...

The astonishing diversity of avian movement patterns, reproductive tactics, and survival rates creates rich opportunities for study, but also presents enormous challenges for explaining variation among life-history traits and dispersal. Dispersal decisions shape the genetic structure of populations and thus can be of considerable importance in processes such as speciation. Moreover, a better understanding of dispersal and movement among populations remains fundamental for effective...

The Ovenbird (Seiurus aurocapillus), is small songbird of the warbler family. Their breeding habitats are mature deciduous and mixed forests, especially sites with less undergrowth, which can be found across Canada and the eastern United States. Ovenbirds migrate to the southeastern United States, the West Indies, and from Mexico to northern South America. This bird seems just capable of crossing the Atlantic, as there have been a handful of records in Norway, Ireland and Great Britain....
