Moose Proliferate, Inbred Wolves Struggle At Isle Royale National Park
2014-05-05 03:45:31

By Jennifer Donovan, Michigan Technological University In the Isle Royale Wolf-Moose Study’s annual report released today, the researchers say that over the past three years, they have tallied the lowest numbers of wolves ever: nine in 2011–12, eight in 2012–13 and nine in 2013–14. During the same period, predation rates—the proportion of the moose population killed by wolves—also dropped to the lowest ever recorded, while the number of moose doubled, to approximately 1,050...

Did Inbreeding Drive Woolly Mammoths To Extinction?
2014-03-26 09:19:04

Lawrence LeBlond for redOrbit.com - Your Universe Online Much of what we know about the Mammoth may be challenged after new research from a Dutch team has found evidence that the massive mammal may have driven itself to extinction due to inbreeding. The evidence comes from an unusual feature found in some mammoth fossils taken from the North Sea. This unusual feature suggested to the research team, led by paleontologist Jelle Ruemer of the Natural History Museum Rotterdam, the...

Females discern male mouse songs to avoid inbreeding Female mice prefer songs of mice that are different from their parents when selecting a mate, according to a study published February 5, 2014 in PLOS ONE by Akari Asaba from the Azabu University, Japan, and colleagues. Furthermore, these preferences may be shaped by early social experiences with their fathers. Many animals can learn the characteristics of a desirable mate when they are young, and this includes the ability to recognize...

Winter Flounder In Long Island's Bays Are Inbred
2013-07-24 09:27:41

The Institute for Ocean Conservation Science Scientists from the School of Marine and Atmospheric Sciences at Stony Brook University advise that loss of genetic diversity presents survival risks for historically common marine fish and should be considered in fisheries management Research conducted in six bays of Long Island, NY, and led by scientists from the School of Marine and Atmospheric Sciences at Stony Brook University (SBU) showed that local populations of winter flounder are...

Ancient Human Skulls Show Evidence Of Prevalent Inbreeding
2013-03-19 15:25:55

Brett Smith for redOrbit.com - Your Universe Online Although it is considered completely taboo in most modern societies, an ancient human skull found in northern China suggests inbreeding could have been prevalent among ancient peoples around 100,000 years ago, according to a report in the open access journal PLoS ONE. The skull — which was found at Xujiayao, a mountainous excavation site several hundred miles from the Mongolian border — contained an enlarged parietal...

Research discovers that whether a female butterfly will mate with a male depends on the quality of his sex pheromones The mating success of male butterflies is often lower if they are inbred. But how do female butterflies know which males to avoid? New research reveals that inbred male butterflies produce significantly less sex pheromones, making them less attractive to females. The research was published today in the journal Proceedings of the Royal Society B. If animals (and humans)...

An article recently published in the Journal of Mammalogy, Volume 94 Issue 6 focuses on the struggling Florida manatee population and analyzes the factors pertaining to their decline. (PRWEB) January 29, 2013 Journal of Mammalogy — There is a better than 49 percent probability that the Florida manatee population will fall below 500 individual animals in the next 100 years, according to one analysis. One of the factors that can drive population decline is a lack of genetic diversity....

Corn Has Many Active Genes, Could Produce High Yield
2012-12-03 11:45:34

University of Bonn Researchers at the University of Bonn investigate 1 of the oldest mysteries of plant breeding Hybrid plants provide much higher yield than their homozygous parents. Plant breeders have known this for more than 100 years and used this effect called heterosis for richer harvests. Until now, science has puzzled over the molecular processes underlying this phenomenon. Researchers at the University of Bonn and partners from Tübingen and the USA have now...

Rare Ethiopian Wolves Under Threat
2012-10-27 07:09:25

April Flowers for redOrbit.com - Your Universe Online Ethiopian wolf populations are genetically fragmenting, scientists say. This is cause for concern because the Ethiopian wolf is the world's rarest canine and fewer than 500 of Africa's only wolf species remain in the wild, according to BBC News. A 12-year study of the wolves, published in the journal Animal Conservation, reveals that there is little genetic flow between the small remaining populations in the Ethiopian highlands,...

Low Genetic Diversity Spells Bad News For Koalas
2012-10-24 14:41:12

Brett Smith for redOrbit.com - Your Universe Online When populations of animals are under threat, a major concern surrounding their potential for survival is the genetic diversity within the population. A high level of genetic diversity makes for a resilient population, while low genetic diversity could be a red flag for conservationists. In a new study, an international team of researchers has investigated the genetic diversity of the koala population and found through both historical...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
