(Press-News.org) ORANGE, Calif. – Chapman University's Walter Piper, Ph.D., has published research this week in a leading science journal that shows animals choose habitat similar to where they were raised rather than that likely to maximize reproductive success. This finding runs counter to current tenets of habitat selection theory.
The paper is published in the Proceedings of the Royal Society B on June 26 and includes co-authors Michael Palmer, Nathan Banfield and Michael Meyer. Dr. Piper's research focuses on his long-term study of loons.
"The basic finding is that young loons chose to settle on territories that are very similar to their natal territories," noted Dr. Piper, professor in Chapman's Schmid College of Science and Technology. "This behavioral pattern seems to indicate that loons choose habitat so as to promote their survival, not their breeding success. This is exciting because it flies in the face of current dogma in field of habitat selection."
Here is the abstract from the research: Scientists have long presumed that animals settle on breeding territories according to the ideal free model, which presumes that animals select habitat that maximizes the number of offspring they can produce. But settlement data often show that, in fact, animals do not select high quality habitat. Indeed, here we report that young common loons have a striking tendency to settle on breeding lakes that resemble their natal lake in terms of both size and pH. Preference for natal like rather than high quality habitat, might allow a young animal to feed on familiar prey and, hence, increase its likelihood of surviving its early breeding years.

Research in fruit flies provides new insight into Barrett's esophagus
2013-06-27
Research focused on the regulation of the adult stem cells that line the gastrointestinal tract of Drosophila suggests new models for the study of Barrett's esophagus. Barrett's esophagus, a risk factor for esophageal cancer, is a condition in which the cells of the lower esophagus transform into stomach-like cells. In most cases this transformation has been thought to occur directly from chronic acid indigestion when stomach contents flow back up into the esophagus. A new study, published June 27, 2013 online in Cell Reports, suggests a different cause, namely a change ...
Stanford scientists discern signatures of old versus young stem cells
2013-06-27
STANFORD, Calif. — A chemical code scrawled on histones — the protein husks that coat DNA in every animal or plant cell — determines which genes in that cell are turned on and which are turned off. Now, Stanford University School of Medicine researchers have taken a new step in the deciphering of that histone code.
In a study to be published June 27 in Cell Reports, a team led by Thomas Rando, MD, PhD, professor of neurology and neurological sciences and chief of the Veterans Affairs Palo Alto Health Care System's neurology service, has identified characteristic differences ...
Imagination can change what we hear and see
2013-06-27
A study from Karolinska Institutet in Sweden shows, that our imagination may affect how we experience the world more than we perhaps think. What we imagine hearing or seeing "in our head" can change our actual perception. The study, which is published in the scientific journal Current Biology, sheds new light on a classic question in psychology and neuroscience – about how our brains combine information from the different senses.
"We often think about the things we imagine and the things we perceive as being clearly dissociable," says Christopher Berger, doctoral student ...
Keeping networks under control
2013-06-27
As the world becomes increasingly connected, the need to ensure the proper functioning of its many underlying networks -- such as the Internet, power grids, global air transportation and ecological networks -- also is increasing. But controlling networks is very difficult.
Now a Northwestern University research team has developed the first broadly applicable computational approach identifying interventions that can both rescue complex networks from the brink of failure and reprogram them to a desired task.
"A fundamental property of networks is that a perturbation to ...
Gene deletion affects early language and brain white matter
2013-06-27
HOUSTON -- (June 27, 2013) – A chromosomal deletion is associated with changes in the brain's white matter and delayed language acquisition in youngsters from Southeast Asia or with ancestral connections to the region, said an international consortium led by researchers at Baylor College of Medicine. However, many such children who can be described as late-talkers may overcome early speech and language difficulties as they grow.
The finding involved both cutting edge technology and two physicians with an eye for unusual clinical findings. Dr. Seema R. Lalani, a physician-scientist ...
Researchers call for rethinking efforts to prevent interplanetary contamination
2013-06-27
PULLMAN, Wash.—Two university researchers say environmental restrictions have become unnecessarily restrictive and expensive—on Mars.
Writing in the journal Nature Geoscience, astrobiologists Alberto Fairén of Cornell University and Dirk Schulze-Makuch of Washington State University say the NASA Office of Planetary Protection's "detailed and expensive" efforts to keep Earth microorganisms off Mars are making missions to search for life on the red planet "unviable."
The researchers claim "the protocols and policies of Planetary Protection are unnecessarily restricting ...
Insights into how brain compensates for recurring hearing loss point to new glue ear therapies
2013-06-27
Important new insights into how the brain compensates for temporary hearing loss during infancy, such as that commonly experienced by children with glue ear, are revealed in a research study in ferrets. The Wellcome Trust-funded study at the University of Oxford could point to new therapies for glue ear and has implications for the design of hearing aid devices.
Normally, the brain works out where sounds are coming from by relying on information from both ears located on opposite sides of the head, such as differences in volume and time delay in sounds reaching the two ...
UCSF researchers discover species-recognition system in fruit flies
2013-06-27
A team led by UC San Francisco researchers has discovered a sensory system in the foreleg of the fruit fly that tells male flies whether a potential mate is from a different species. The work addresses a central problem in evolution that is poorly understood: how animals of one species know not to mate with animals of other species.
For the common fruit fly D. melanogaster, the answer lies in the chemoreceptor Gr32a, located on sensory neurons on the male fly's foreleg. "In nature, this sensory system would prevent the creation of hybrids that may not survive or cannot ...
Power for seaports may be the next job for hydrogen fuel cells
2013-06-27
LIVERMORE, Calif.— Providing auxiliary hydrogen power to docked or anchored ships may soon be added to the list of ways in which hydrogen fuel cells can provide efficient, emissions-free energy.
Hydrogen fuel cells are already powering mobile lighting systems, forklifts, emergency backup systems and light-duty trucks, among other applications. Now, researchers at Sandia National Laboratories have found that hydrogen fuel cells may be both technically feasible and commercially attractive as a clean, quiet and efficient power source for ships at berth, replacing on-board ...
