Protecting diversity on coral reefs: DNA may hold the key
Research published today by a team of scientists discovered that large areas of intact coral reef with extensive live coral cover, not disturbed by humans or climate change, harbor the greatest amount of genetic diversity. With this work, the researchers uncovered a link between species diversity of an ecosystem and the genetic diversity encoded within the DNA of those species. (2016-04-27)

Little-Explored African Genetic Diversity May Hold Key To Human Origins, Medical Questions
Genetic diversity in Africa is extremely high, even between closely related or located groups and much higher than diversity in other human populations. This diversity suggests a recent African origin for modern humans and a raft of potentially fertile medical research, according to a Penn State evolutionary biologist. (1999-01-22)

Are humans changing animal genetic diversity worldwide?
Human population density and land use is causing changes in animal genetic diversity, according to researchers at McGill University. The findings reported in the journal Ecology Letters, show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals. The evidence for human impacts was most clear for insects and fish species. (2019-10-22)

DNA may hold clues to Red Tide origins
Where do the Red Tides invading Texas coastal waters originate? That's what Texas A&M University oceanographer Lisa Campbell is trying to find out as she attempts to use DNA markers known as microsatellites to identify the genetic diversity with blooms of Karenia brevis, the species of phytoplankton causing Red Tides. Red tides occur unpredictably in the Gulf of Mexico and result in fish kills and, sometimes, human illnesses. (2002-08-14)

(2018-02-07)

Researchers find low genetic diversity in domestic ferrets
Researchers reported that the domestic ferrets in North America and Australia had extremely low genetic diversity, whereas ferrets in Europe had higher genetic diversity, as periodic hybridization with wild polecats appears to occur. However, all the countries sampled had ferrets with lower genetic diversity than their wild ancestors. (2017-11-01)

Dog DNA tests alone not enough for healthy pedigree, experts say
Breeding dogs on the basis of a single genetic test carries risks and may not improve the health of pedigree lines, experts warn. Only a combined approach that makes use of DNA analysis, health screening schemes and pedigree information will significantly reduce the frequency of inherited diseases, according to a review of the practice by researchers at the University of Edinburgh's Roslin Institute. (2015-03-04)

Kill the cancer, not the patient: New toxicity testing approach could make chemo drugs safer
With a new two-year, $1 million grant from the National Cancer Institute, Jackson Laboratory Professor Gary Churchill is launching a radical new approach to testing three chemotherapeutic drugs for potential toxic effects, using an outbred mouse population that approximates the genetic diversity observed in human populations. (2009-11-18)

Duckweed: The low-down on a tiny plant
An international research team led by researchers from the University of Münster and the Max Planck Institute for Chemical Ecology (both Germany) have found why the giant duckweed has a low genetic diversity despite its large population size: low mutation rates contribute to low genetic diversity. The results are relevant for future studies on the evolution of plants and will accelerate the use of duckweeds both for basic research and industrial applications. The study was published in ''Nature Communications''. (2019-03-26)

Scientists call for increased conservation efforts to save black bears
To combat the decline of black bears and repopulate the mountainous region of the Central Interior Highlands, more than 250 bears from Minnesota and Manitoba were relocated to Arkansas in the 1950s and 1960s. Now, researchers at the University of Missouri have analyzed genetic diversity in black bears in the CIH and have determined that coordinated conservation management is still needed to maintain healthy populations of black bears in the region. (2014-08-04)

Understanding apples' ancestors
Wild Malus orientalis -- a species of wild apples that could be an ancestor of today's domesticated apples -- are native to the Middle East and Central Asia. A new study comparing the diversity of recently acquired M. orientalis varieties from Georgia and Armenia with previously collected varieties originating in Russia and Turkey narrows the large population and establishes a core collection that will make M. orientalis more accessible to the breeding and research communities. (2009-12-10)

New map of variation in maize genetics holds promise for developing new varieties
A new study of maize has identified thousands of diverse genes in genetically inaccessible portions of the genome.

Birds of a feather
Biologists have always been fascinated by the diversity and changeability of life on Earth and have attempted to answer a fundamental question: How do new species originate? A new study provides the first large-scale test of the link between population differentiation rates and speciation rates. The results confirm the evolutionary importance of population genetic differentiation. (2017-06-13)

New methods to study 'genetic invasion' detect the escape of crop genomes into the wild
Agricultural practices create opportunities for crop DNA to invade wild plant gene pools. This allelic introgression concerns conservationists because the resulting changes in genetic diversity can reduce a population's ability to withstand changes like climatic shifts, disease, or pest outbreaks. In a new study, researchers found substantial flaws in traditional methods used to track crop-wild gene flow, and developed a new, more sensitive approach to test agricultural systems for risk assessment of transgene escape. (2016-04-05)

Rare sharks are no longer in the 'dark,' thanks to new species survey method
Previously unobserved shark species swim in areas impacted by humans, reports a new study. The results reveal a greater prevalence of sharks in such regions than traditional survey methods have uncovered, and the approach for uncovering them may lead to more thorough species diversity assessments in areas with rare and threatened large animals - often hard to (2018-05-02)

Ancient wild horses help unlock past
An international team of researchers has used ancient DNA to produce compelling evidence that the lack of genetic diversity in modern stallions is the result of the domestication process. The team, which was led by Professor Michi Hofreiter from the University of York, UK, has carried out the first study on Y chromosomal DNA sequences from extinct ancient wild horses and found an abundance of diversity. (2011-08-23)

Climate change affects the genetic diversity of a species
What effects does climate change have on the genetic diversity of living organisms? In a study led by Charité - Universitätsmedizin Berlin, an international team of researchers studied the genome of the alpine marmot. Results were unexpected: the species was found to be the least genetically diverse of any wild mammal studied to date. The alpine marmot has lost its genetic diversity during ice-age related climate events and been unable to recover its diversity since. (2019-05-23)

Removing race from human genetic research
When it comes to studying human genetic diversity, a group of scientists, including Drexel's Michael Yudell, feel that the race concept has no place in human genetics. (2016-02-04)

Evolution in action: How some fish adapt to pollutants
New genetic analyses of fish reveal how some have managed to evolve and adapt to live in polluted water. The results suggest that the high genetic diversity exhibited by these fish was key -- a palette for natural selection to act on to facilitate the population's rapid adaptation to extreme pressures. (2016-12-08)

Manatee subspecies genetically confirmed, but diversity challenge looms
The first genetic study to compare nuclear DNA of endangered Antillean manatees in Belize with Florida manatees confirmed their designation as separate subspecies.
