|CANBERRA Nike Air Max 97 Summit Wit Schoenen Kopen , Aug. 9 (Xinhua) -- Two separate studies undertaken by scientists in Australian have come up with new ways to deal with the eradication of pests such as feral pigs, rabbits and mice, which cost the local agricultural economy more than one billion Australian dollars (800 million U.S. dollars) every year.
Researchers from the Commonwealth Scientific and Industrial Research Organization (CSIRO) has developed a technology-based system whereby pests get scared away from crucial agriculture, while in a separate development, researchers from the University of Adelaide attacked the problem using complex genetic development.
CSIRO scientist Dr Ash Tews said that the trials of autonomous Vertebrate Pest Detect-and-Deter (VPDaD) technology are underway Nike Air Max 97 OG Undefeated Groen Oranje Kopen , which uses a series of sensor-driven lights and sounds to prevent pests from causing damage.
"One of the interesting issues with existing deterrent technologies is that, not only do animals become de-sensitized to them, but smarter ones can even learn to use the deterrents as an indication of a food source, which is the opposite of their purpose," Tews was quoted in a CSIRO press release published on Wednesday.
The autonomous technology CSIRO scientists developed allows the system to recognize animal behaviours in response to deterrents and modify the deterrent strategy until the desired effect is achieved.
"This allows the system to be more effective over long periods of time such as the key threat times during crop growing."
Tews said while the technology was only in a testing phase Nike Air Max 97 OG Undefeated Rood Wit Kopen , ultimately the CSIRO wants to "scale-up the technology and roll it out across Australia".
And while the CSIRO has been busy implementing technology in the fight against invasive and damaging pest species, scientists at the University of Adelaide in South Australia believe they may soon be able to eradicate pests by implanting them with "infertility genes".
According to the university's mathematical ecologist, Dr Thomas Prowse, researchers could use a process called gene drive to cause an inheritance of a gene which would render pests, such as mice Nike Air Max Classic BW Dames Kopen , infertile.
In a press release also published on Wednesday, Prowse said that if 100 "infected" mice were released on, for example, an island of 50,000 mice Nike Air Max Classic BW Heren Kopen , they would be eradicated within five years.
"If viable, this technology offers a humane, targeted solution for invasive species control," Prowse said.
"This could complement or even replace traditional control methods such as culling, trapping and poison baiting Nike Air Max Classic BW Kopen , as well as more advanced biocontrols such as rabbit haemorrhagic disease."
The research indicates that controlling invasive pest populations using gene drives may be feasible, but certainly the hype around this new technology is still some way ahead of the science.
Prowse's colleague and molecular geneticist at the university, Professor Paul Thomas said that new "CRISPRCas9 gene editing technology" was responsible for the breakthrough.
"(This new) gene editing technology enables the gene drive to replicate itself during egg and sperm production this ensures that it is passed on to the next generation and ultimately results in spread through the entire population," Thomas said in the press release.
"Our results indicate that placing the gene drive in a fertility or viability gene will eventually cause the population to crash."
He said there was still lab work to be conducted to ensure the process of gene driving works, implementation of such a plan was still some time away.
"The next necessary step will be development of gene drives in laboratory mice under secure conditions to enable improved modelling of this potential for pest eradication Nike Air Max 2018 Kopen ," he said.
"This will provide the critical data needed to debate the important questions that remain around biosecurity, regulation and ethics."

NAIROBI, Aug. 4 (Xinhua) -- Kenyan President Uhuru Kenyatta on Friday urged nationals to come out in large numbers and vote peacefully on Aug. 8 Nike Air Max TN Kopen , assuring that adequate steps have been put in place to ensure their safety.
Kenyatta, when interviewed by radio journalists in Nairobi, called on voters to ensure they exercise their democratic right by choosing their leaders, stressing the 2017 election will be determined by the turnout.
"We urge Kenyans to continue maintaining peace and co-exist peacefully. They should not fight because of politics," Kenyatta said Nike Air Max 96 Kopen , according to a statement released by his office.
The elections are planned for the President, members of the Senate, Parliament, governors for 47 county governments, members of the regional Parliaments and representatives of youth and women.
President Kenyatta expressed confidence that Kenyans will vote for Jubilee based on its outstanding development track record.
Next week's elections come amid far-reaching institutional reforms that have seen new officers take oath of office after an elaborate appointing procedure.
Observers say the 2007 and 2008 post election violence experience was a reminder of the significance of building strong institutions of governance.
Kenyatta said once given a second term Nike Air Max 95 Kopen , Jubilee will be able to complete the projects it has initiated that are at different stages of completion as well as start new ones that will continue to improve the livelihoods of citizens.
He pointed out that his administration's track record sp.
