Cover crops increase destruction of weed seed in fields, shed light on predator interactions

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Cover crops have been promoted for their abilities to reduce erosion and retain or enhance soil nutrients. Now there is evidence that they can significantly reduce weed seeds from entering the soil seed bank.Crops such as red clover, planted after a main crop’s harvest, often are used to provide cover for insects such as ground beetles that feed on weed seed scattered along the soil surface. Beetles remove the seeds before they are tilled under and become part of the field’s long-term seed bank. Rodents are also important consumers of weed seeds and, like beetles, tend to prefer foraging under the shelter provided by cover.As a result, in fields planted with cover crops, three to four times more weed seed is eliminated from the combination of beetles and rodents, according to recent research.While that result wasn’t unexpected, Ian Kaplan, a Purdue University associate professor of entomology, and Carmen Blubaugh, who earned her doctorate at Purdue and is now a postdoctoral research associate at Washington State University, used field experiments to learn a little about how habitat and fear might cause ripples along the food chain and affect seed predation.Beyond eating weed seeds, rodents also attack seed-feeding beetles, making it a challenge to predict seed consumption rates where both mice and beetles coexist. Each face numerous threats that change their approaches to finding food. On dark nights, for example, rodents might roam open fields. But under a moonlit sky, they are vulnerable to nocturnal predators.“We know moonlight has this predictable effect on small mammal behavior,” said Blubaugh, whose findings were published in the journal Oecologia. “When the moon is full, small mammals hide under the protection of cover. It helps them avoid predators that fly at night.”Kaplan and Blubaugh assumed that increasing the amount of light would drive rodents to cover more often, increasing the number of beetles they ate. If that were the case, reducing the beetle population might increase the amount of weed seed left in a field.In field experiments, they artificially manipulated “moonlight” in fields using lanterns to simulate a full moon. They indeed found fewer beetles under the illuminated cover crops, but instead of reducing the rate of weed seed consumption, the light treatments had no effect.“This is particularly surprising and interesting since rodents had strong negative effects on beetle densities,” Kaplan said. “Theory predicts that this interaction — called intraguild predation — will disrupt biocontrol, especially when the weaker seed predator (rodents) attacks the more effective predator (beetles).”In lab tests, exposure to a rodent decreased the movement of beetles, likely their way of becoming less noticeable to the predators. But surprisingly, the beetles ate 50% more seeds, despite the risk of being eaten themselves.“Beetles reduce their movement, but it might just mean that they hunker down on a pile of seeds and use that as a resource instead of hunting around for higher quality food,” Blubaugh said.Blubaugh expects to continue studying the interactions among animals and insects to understand how they’re affected by fear and risk. She said a study of animal feces could inform how diets change in response to fluctuating risk.The National Science Foundation and the U.S. Department of Agriculture’s National Institute of Food and Agriculture funded Kaplan and Blubaugh’s research.last_img read more

How Not To Be A Sales Poseur

first_img Get the Free eBook! Want to master cold calling? Download my free eBook! Many would have you believe that cold calling is dead, but the successful have no fear of the phone; they use it to outproduce their competitors. Download Now My friend Mike Weinberg says “No one defaults to prospecting.” What he means is that when salespeople have time between calls or meetings, they don’t automatically pick up the phone and start prospecting. And he’s right about this.When I was a young salesperson, there was only the phone. Every morning, I secluded myself in an office and made prospecting calls. I started making calls at 8:15 AM, and I stopped for lunch at Noon, when I’d usually go to a restaurant with my peers. After lunch, I’d start making calls again until it was time to go home.As I made calls to every number in the business section of the phonebook, I wrote down every “good” lead on an index card. If someone told me that they used what I sold, they were a good lead. The next day, I’d flip through all of those index cards, knowing that they were better than the numbers in the phonebook. Then I started back through the phonebook. No targets. No business intelligence. No social networks. No LinkedIn. No research.It was prospecting. All day. Every day. And then the appointments came. And after I made a sales call, it was back to prospecting. Lots of people were better salespeople than I was. No one made more calls. Prospecting was my default.As a young salesperson, no one had to tell me to prospect. I didn’t know what else I should have been doing. And there still aren’t many real choices available to you. When you need new business, you make your calls.Don’t be a sales poseur. Pick up the telephone.I made two cold calls today. Dave Brock and his team make calls every week.last_img read more

‘Tourists like fish more than beef’

first_imgGoa’s Minister for Tourism Manohar Ujgaonkar on Thursday said fish and not beef was the food preferred by tourists and the Centre’s notification banning the sale of cattle for slaughter will have no impact on the flow of tourists to the State. Over six million tourists, both domestic and foreign, visit the State every year.Mr. Ajgaonkar said, “Just as Goa is known for its sun and sand, it is also known for its fish, curry and rice. Goan fish curry is a big draw for tourists who love authentic Goan xit kodi [fish curry] and sea food. Other non-vegetarian dishes are always the second choice. Goa therefore has not really been affected by the beef notification.”Mr. Ajgaonkar said there was no beef shortage in Goa, but tourism industry stakeholders and meat traders are worried the order banning the sale of cattle for slaughter in animal markets would badly hit sale of beef. Over 30% of the State’s population compirse of people of minority communities who consume beef regularly.Francisco Braganca, hotelier and former president of the Travel and Tourism Association of Goa, said hoteliers worry that fears of beef shortage could lead traders hoarding stocks and creating articifical scarcity. He said, “I am told by many supermarket stores owners that there is no impact on the supply of beef as of now. Cattle continues to come in from Karnataka, but the beef is sold out instantly. People perceive a shortage and are hoarding beef.”He said tourists continue to flock to the State as it’s hotter in the other parts of the country.last_img read more

Scientists grow tiny human stomachs in lab dishes

first_imgThe colorful snakelike image above is actually fluorescently labeled tissue from a section of a stomach that’s smaller than a pea. But it’s not the stomach of an extraordinarily small animal; it’s a mini human stomach grown in a dish by scientists who hope to use it to study gastrointestinal diseases. Because the digestive systems of mice, flies, and other model organisms differ from those of humans, researchers have been hard-pressed to find a way to study the development of human gut maladies such as peptic ulcer disease. So several groups have turned to pluripotent stem cells—cells derived from human embryos or reprogrammed adult cells that can turn into any cell type in the body—to try to grow digestive organs in the lab. Last week, one group of researchers announced the creation of a lab-grown small intestine from stem cells. Today, a different team reports online in Nature that they’ve perfected the recipe of molecules needed to coax both types of stem cells to grow into small spheres that, despite their size, have all the properties of a functional stomach. When the researchers exposed the ministomachs to the bacterium Helicobacter pylori, infections of which are blamed for many stomach ulcers and cancers, they saw the same molecular and cellular changes already known to occur in life-size stomachs.last_img read more

Ind vs Eng: Sunny, Holding slam Dhoni and Co

first_imgFormer captain Sunil Gavaskar has blamed poor technique of Indian batsmen for the team’s dismal show in the Test series in England, saying the tourists have looked like a “school boys’ team”.Team India was found wanting in all three departments of batting, bowling and fielding as they were outplayed by the English side.Down 2-nil in the series, Team India’s two losses in the series have exposed a lot of chinks in their armour and experts worry that if India does not improve immediately M.S. Dhoni’s team stand to lose their top Test ranking.Scathing in his criticism of the world number one side, Gavaskar states that the Indians have been “totally outplayed by England in the second Test so much so that it looked like a contest between a professional team and a school boys’ team”.Gavaskar elaborates, “The batting has failed to get to 300 in four innings and the bowling in both Tests has faded away after a bright beginning”.Talking specifically about the batsmen, the master criticises the batting technique of both the seniors and the youngsters in the side: Getting onto the front foot and they suddenly find that when it comes to overseas pitches and the quicker bowlers, “they just don’t know how to play off the back foot”.India just does not care about international commitments: HoldingThe poor show by Dhoni and company in England is drawing flak world wide.Legendary West Indian fast bowler Michael Holding has slammed Indian cricketers for below average performance so far, even claiming that it was the money that was on offer in the IPL that had ensured that the Indians just did not care about their international commitments.  The former pacer questioned why none of the players pull out of IPL with injuries, suggesting that the money on offer ensured that international commitments take a back seat.  Holding went on to accuse Team India of neither playing like world champions nor putting in extra effort.advertisementlast_img read more

Chris Gayle is special and a hero to young players, says Darren Bravo

first_imgWest Indies batsman Darren Bravo has paid a rich tribute to Chris Gayle, calling the opening batsman a “hero to the young players”. Gayle will retire from one day internationals after the ICC Cricket World Cup 2019 to be held in England and Wales.”He’s definitely a hero to the young players. Not even a hero; he’s a legend. The experience of having Chris in the dressing room is priceless. He puts a smile on each and every player’s face. And, as you can see when we go out there, we really enjoy our cricket,” Bravo was quoted as saying by ICC.Gayle holds the record for most centuries by a West Indian in ODIs, with 24, as well as the highest score of 215, which he scored in the last edition of the ICC Cricket World Cup in 2015 against Zimbabwe. Gayle is also handy with the ball, picking up 165 wickets.”If you look at the stats, he’s achieved a lot at the international level. He’s a special player. We’re really happy to have him,” he added.Bravo said that Gayle is still an asset for the team and is the one who always helps the youngster with their game.”He’s getting on a bit in age, but he’s still striking the ball nicely, so that is the most important thing,” he said.”And in the dressing room, he’s always giving information, he’s helping all the youngsters. I think over the last few years he’s changed the game a little bit. He’s not going so hard as before. He understands his game pretty well,” he said.advertisement”As long as it all goes well, as far as his approach is concerned, I don’t see any reason we can’t consistently cross the 300 mark,” he added.The left-hand batsman, who made a comeback after being out of action for sometime, said that he is quite happy with the current atmosphere in the dressing room and is enjoying his style of play.”I’m happy; the guys are smiling. It’s always good to have the best of both worlds. It’s a good feeling. There’s a nice gel of experience and young guys. The fans are enjoying our style of play, which is the most important thing,” Bravo said.West Indies, who are currently playing a five-match ODI series against England at home, open their World Cup campaign against Pakistan on May 31.Also Watch:last_img read more

Legal action mulled over Indian Affairs contract given to exofficial

first_imgATPN National NewsOTTAWA–A Manitoba grand chief is considering legal action against Indian Affairs over the department’s decision to award a $25,000 contract to a former bureaucrat for a review of programs in the same branch where the official once worked.Manitoba’s Southern Chiefs Organization Grand Chief Morris Shannacappo said he is troubled by the department’s silence on the contract which was rescinded after a complaint was issued to the minister of Indian Affairs.The deputy minister of Indian Affairs has also been asked by the watchdog that oversees federal procurement to probe the awarding of the contract.Shannacappo said he has failed to get any explanation from the department on the contract, which was awarded to the non-Aboriginal former bureaucrat under a special program for Aboriginal businesses.Now he wants to explore whether the department broke any laws.“I would like to get a legal opinion on it,” he said. “I would like to take it to a lawyer to see if we can go (the legal) route.”Indian Affairs announced it had awarded a contract to review its economic development programs on June 29 to Radek Bandzierz, who worked in the department’s Aboriginal Business Canada section and retired in the fall of 2009.The contract was rescinded in August after the issue was taken by Shannacappo’s organization to the minister’s office.In an Oct. 13 letter, obtained by APTN National News, federal deputy procurement ombudsman Oriana Trombetti asked deputy minister Michael Wernick to consider reviewing the contract’s awarding. Trombetti cited concerns from the chief’s organization over possible conflicts of interest and fair competition.Trombetti said the contract fell outside the ombudsman’s mandate because it was initially awarded under the Aboriginal set-aside program and was eventually rescinded.Indian Affairs would only confirm it had received the letter and that it would receive a response. A spokeswoman said the response constituted private correspondence and would not be revealed.Shannacappo said the affair is an example of how the government doesn’t walk the talk on accountability.“There is a lot of pressure being put on (First Nations) leadership to be accountable, but accountability is a two-way street,” he said.last_img read more
