Genetic tests pin down origins of island-hopping rodents


Rat Price of viagra, After managers try to eliminate an invasive species from an ecosystem, the pests can sometimes turn up again. But are the animals survivors of the eradication or new invaders from a different region?


The answer is important for pest managers because it determines whether the original eradication attempt worked, No rx viagra, researchers say in Biological Invasions. If the animals are survivors, the strategy may need to be changed – a potentially costly process, viagra thailand net shop. On the other hand, Generic viagra & canada, a reinvasion might mean that security needs to be strengthened.


The team studied one scenario at Pearl Island, New Zealand, an area that was invaded by three rat species, buy viagra nairobi. After managers attempted to stamp out the pests in 2005, Best online viagra site, 13 rats were found in 2006, and one species spread across the island by 2007. To find out where the rodents had come from, the researchers analyzed the DNA of rats from Pearl Island, both before and after eradication, as well as from neighboring Stewart Island.


The newly discovered rats bore the genetic traits of the Stewart Island population, the team concluded, price of viagra. So while the eradication succeeded, Pfizer brand viagra discount, rats appear to be swimming to Pearl Island faster than expected. Viagra mfg by, The researchers say that similar tests could be used to evaluate other eradication campaigns, as long as managers collect samples of the species before removal. – Roberta Kwok

Ordering Viagra Online Legally




DNA barcodes could assist tracking of illegal bushmeat


Alligator Ordering viagra online legally, Officials struggling to monitor the flourishing bushmeat trade may soon get some help. Researchers say that a simple genetic test called DNA barcoding can distinguish many wildlife species, offering a possible way to identify illegal animal products.


Bushmeat is now exported across the world, fda legally import viagra, with illegal trade estimated at $5 billion to $8 billion per year. Cheap viagra no prescription west coast, Some species are protected under laws and treaties, but determining the identity of a wildlife product can be difficult because the animal is usually processed.


The researchers analyzed specimens of frequently hunted species from Africa and South America, including antelope, cheap no prescription viagra, monkeys, Bells palsy and viagra, alligators, and crocodiles. They were able to extract high-quality genetic data from 88 percent of their samples, purchase viagra from canada, even specimens that were more than two decades old. Canadian healthcare viagra, Closely related species showed an average of 9.8 percent difference in a key gene fragment, the team reports in Conservation Genetics.


Investigators could check for these unique DNA sequences, or barcodes, buy viagra without prescription, to accurately identify wildlife products from endangered species, Viagra side effects, the authors say. The team is now developing a test that would allow even more degraded samples to be analyzed. – Roberta Kwok

Tooth and paw



Genetic analysis reveals the real culprit behind Scandinavian sheep kills bad to the boneBiologists at Uppsala University, Sweden, have successfully extracted DNA from saliva around bite wounds in two savaged sheep. Carles Vilà and colleagues swabbed the grisly remains, used some clever machines to get the DNA out, and compared their findings against known genetic sequences. Wolves Canis lupis perusing the online pages of Conservation Genetics will no doubt delight in discovering that the predator responsible was in fact a single very naughty dog -- the two faithful farm mutts have also been ruled out of the investigation. The technological advance should ensure that wolves aren’t made into scapegoats, so to speak, and blamed unfairly for crimes they did not commit. You see how science can make us all more happy? Except sheep, of course. Source: Sundqvist A-K, Ellegren H & Vilà C (2007) Wolf or dog? Genetic identification of predators from saliva collected around bite wounds on prey.

A twist in the tail



What's the cure?Molecular study reveals unexpected source in Chinese traditional pharmacies A bunch of shriveled seahorses Hippocampus spp. has surprised a group of Stanford scientists led by the intrepid Steve Palumbi. Having scoured San Francisco’s Chinatown apothecaries and curio shops for dried specimens, Palumbi’s team carried out DNA tests to work out where the unfortunate fish came from. Reporting in Conservation Genetics, they describe how almost two thirds of their sample originated from the Eastern Pacific, rather than the Indo-Pacific as expected. The findings underscore the urgent need to learn more about both seahorse fisheries and their ecology and behavior. Twenty six of the 34 known species are described by the IUCN as “data deficient”, the remaining eight are classified as Vulnerable or Endangered.
