Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored A new paper reports that Foxlights, a brand of portable, intermittently flashing lights, kept pumas away from herds of alpacas and llamas during a recent calving season in northern Chile.Herds without the lights nearby lost seven animals during the four-month study period.The research used a “crossover” design, in which the herds without the lights at the beginning of the experiment had them installed halfway through, removing the possibility that the herds were protected by their locations and not the lights themselves. Pulsating lights placed around llama and alpaca herds warded off puma attacks during a recent experiment in Chile, suggesting the method might help avert conflict between herders and dwindling populations of the predator.“The implications are huge,” Omar Ohrens, a postdoctoral scholar in environmental studies at the University of Wisconsin, Madison, and lead author of a study on the findings, said in an interview.The landscape of the Andean Plateau in Chile, with the village of Chulluncane in the foreground. Image by Omar Ohrens.In the study by Ohrens and his colleagues published online Jan. 3 in the journal Frontiers in Ecology and the Environment, pumas left herds alone that had Foxlights set up close to the llamas and alpacas’ sleeping areas during a recent four-month calving season. During the same period, cats killed seven animals from herds that did not have the lights, which blink in a random pattern designed to mimic a person walking with a flashlight and other human activity.The puma (Puma concolor) is a critical part of the ecology of the high plains of the Andean Plateau, also called the Altiplano, of northern Chile. Such large predators regulate the number of herbivores on the landscape, keeping the entire ecosystem in balance.But when mountain lions pick off livestock, it threatens the livelihoods of the people who depend on that resource. In a 2016 study, Ohrens and his colleagues reported that pastoralists in this part of Chile estimate they lose 10 percent of their animals each year to pumas.A puma track spotted near the study site. Image by Omar Ohrens.The pumas, too, are at risk following these incidents, as herders look to eliminate the threat. But research has shown that killing a predator suspected of targeting livestock doesn’t always work, Ohrens said. What’s more, his earlier surveys of the Aymara llama and alpaca herders of the Altiplano revealed that most people didn’t want to kill pumas. That led Ohrens to find a way to identify and test a potential, non-lethal solution to this problem.In the planning stages of this study, he asked the herders themselves to choose from a variety of potential non-lethal deterrents, and they settled on Foxlights. Developed in Australia to keep young lambs safe from foxes, Foxlights also fit the grasslands of northern Chile. The wide-open plains of the Altiplano allow for the lights to be seen from as far away as 1.6 kilometers (1 mile), according to the manufacturer. And the sunlight that bathes the plateau, which sits between 3,000 and 5,500 meters (9,800 and 18,000 feet) above sea level, can recharge the lights’ batteries during the day.Researchers set up a camera trap near the study site. Image by Omar Ohrens.During the calving season in late 2016 and early 2017, Ohrens and his teammates compared the incidence of livestock kills in herds with lights installed nearby to deaths in herds without them.To make sure that they weren’t just witnessing a single puma zero in on herds without lights — an unlikely, but possible, situation given the large home ranges of pumas, the authors write — they set up camera traps around the herds of the 11 farmers who were part of the study. The images confirmed that at least three different cats were in the area.In a twist, Ohrens found that the lights did not spook off Andean foxes (Lycalopex culpaeus) going after young lambs. That didn’t come as a shock to Ohrens, who has worked in this part of his native Chile for seven years.Villablanca Lagoon and Sillajuay Mountain in the Andean Plateau. Image by Omar Ohrens.“What I’ve seen is that Andean foxes are not very scared of humans — they can get pretty close and even take food from people’s hands,” he said in a statement. “So they’re not going to be scared by lights that simulate human activity.”To further bolster the study’s rigor, the team also moved the lights partway through the experiment from the herds that had them at the beginning of the study to the ones that didn’t. They got similar results, demonstrating that the location of the herds didn’t determine whether the lights were effective.“That’s why this study is so important,” Adrian Treves, a co-author of the study and professor of environmental studies at the University of Wisconsin, said in the statement. “Omar’s study shows that non-lethal methods have been proven effective in multiple settings with different livestock and carnivores.”Banner image of study participants setting up a Foxlight next to a livestock sleeping site by Omar Ohrens. John Cannon is a Mongabay staff writer based in the Middle East.

Biochemists launch crowdsourcing site to combat bad data

first_imgChemists looking to design and test new medicines are awash in a sea of bad data, according to a report released today by an international panel of experts. The panel, made up of researchers from 46 nonprofit institutions, universities, and biotech and pharmaceutical firms, say they are setting up a TripAdvisor-like crowdsourcing portal to disseminate up-to-date information about chemical probes that they see as the heart of the problem.The issue with faulty chemical probes has been growing rapidly in recent years. These small, druglike molecules are used primarily to block the activity of specific proteins to determine their roles in biochemistry. Ideally, this helps researchers design drug compounds that perform similar functions but retain attributes needed for successful medicines, like nontoxicity and the ability to travel through the human body. Today, thousands of such probes exist. But most of them interact with nontarget proteins as well or have other unwanted “off-target” effects.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)“It’s become a really serious problem,” says Paul Workman, a chemical biologist and chief executive of the Institute of Cancer Research (ICR) in London, who was a member of the expert panel. The upshot, say Workman and others, is that many probes produce spurious results that can lead researchers to wrong conclusions about the proteins and drug molecules they are studying. For example, some probes have been found to cause side effects, such as triggering chemical changes in proteins or causing proteins to clump together in aggregates that damage cells. And that, the panel argues today in a commentary in Nature Chemical Biology, leads to uncounted hours of wasted time, effort, and money on the part of biomedical researchers. Several years ago, for example, poor chemical probe data led researchers to pursue a final stage clinical trial on a cancer drug candidate called iniparib. Such trials typically cost hundreds of millions of dollars. In 2011 iniparib was deemed a failure after it was found to be less effective at hitting its target than initially thought.Despite such failures, researchers often continue to use faulty probes. Up to now, chemical biologists have relied on the normal self-correcting mechanisms of science—journal articles, reviews, and conference proceedings—to set the record straight. But they haven’t worked in this case. “The self-correction has not been effective enough,” Workman says. The issue, he says, is that few researchers have the time or expertise to keep track of exactly which probes are proving successful. Instead, when researchers look for a new probe, most simply go to Google Scholar and gravitate to the probes that have the most citations. But these are often the older, less reliable probes, Workman says. One such probe, known as LY294002, has had 30,000 citations since 1994 and 1100 since the start of 2014. However, Workman says, “It’s a terrible compound, 10 years out of date, with lots of off-target effects.” More accurate probes have been on the market for years, but researchers still use LY294002 because it appears to have a strong track record.Chemical biologists say they hope crowdsourcing will solve the problem. They have set up a new wiki site, called the Chemical Probes Portal, with backing from ICR, the Broad Institute, the Structural Genomics Consortium, and the Wellcome Trust. At the site researchers will be able to add annotations to different chemical probes, to ensure their colleagues have the most up-to-date comparative information they need. The effort could be a challenging one, because even studies that use the same probe often use it in different conditions and at different doses, says Kevan Shokat, a chemical biologist at the University of California, San Francisco. However, he adds, as long as researchers use the portal in an iterative way to steadily improve the understanding of different probes, it should help the community. “I do think that would be a good service,” Shokat says.last_img read more
