Genetic Diversity Is Key To Tiger Conservation

Genetic Diversity Is Key To Tiger Conservation

Brett Smith for redOrbit.com - Your Universe Online While many tiger conservation efforts focus on the numbers of a population, maintaining the big cats’ genetic diversity is just as important, according to a report published on Thursday in...

Physicists play with the genetics of populations What happens when physicists play (using mathematical instruments) with the genetics of populations? They may discover unexpected connections between migration and biodiversity, for example, as recently done by a group of researchers from the International School for Advanced Studies (SISSA) in Trieste and the Polytechnic University in Turin in a study published in the journal Physical Review Letters. The effect of migration on...

Scientists Identify Factors Limiting Hybridization Of Closely-related Woodrat Species
2014-03-31 08:41:24

Wildlife Conservation Society A pair of new studies from the Wildlife Conservation Society, Idaho State University, and the University of Nevada Reno look at the surprising variety of factors that prevent two closely related species of woodrats from becoming a single hybrid species despite the existence of hybrid individuals where the two species come into contact. After finding that two closely related species, the desert and Bryant's woodrats, could interbreed and produce hybrid...

Cocaine And Methamphetamine Response Differ Between Two Substrains Of 'Black 6' Laboratory Mouse
2013-12-20 06:45:36

Jackson Laboratory Researchers including Jackson Laboratory Professor Gary Churchill, Ph.D., have found a single nucleotide polymorphism (SNP) difference in cocaine and methamphetamine response between two substrains of the C57BL/6 or "Black 6" inbred laboratory mouse, pointing to Cyfip2 as a regulator of cocaine response with a possible role in addiction. The research team, led by Joseph Takahashi, Ph.D., of University of Texas Southwestern Medical Center and the Howard Hughes Medical...

Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or...

Historical records are often used to learn about ancestry but a new approach, using genetics, is currently being applied. In a recent study, published in PLOS Genetics, scientists from the Stanford University School of Medicine and the University of Miami Miller School of Medicine compared patterns of genetic variation found in populations in and around the Caribbean. They were able to discern an influx of European genes into the native population that occurred within a generation of...

Those of us who want to learn about our ancestors — who they were, where they came from and how they mingled (or didn't) with others around them — often turn to historical records or elderly family members for answers. But a new study by researchers at the Stanford University School of Medicine and the University of Miami Miller School of Medicine indicates that the answers can also be found within our own genes. The researchers compared patterns of genetic variation found in...

Bitter Taste Gene May Have Been Beneficial To Human Evolution
2013-11-12 13:31:37

Brett Smith for redOrbit.com - Your Universe Online It can be puzzling sometimes when someone else finds the taste of your favorite food to be disgusting, but research has shown we all perceive the taste of various compounds differently. A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the...

The latest study was published online in Nature Genetics Coding variants in immune disease-related genes play only a small part in the overall genetic risk for psoriasis, according to a new study led by Anhui Medical University and BGI. This conclusion is strongly supported by their investigation on the contribution of functional coding variants to psoriasis in 21,309 Chinese individuals. In such a large-scale investigation, researchers only discovered two independent low-frequency...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...
