Ice nucleation and freezing tolerance in New Zealand alpine and lowland weta, Hemideina spp. (Orthoptera; Stenopelmatidae)

first_imgAbstract.The alpine tree weta Hemidiena maori Pictet et Saussure (Orthoptera: Stenopelmatidae) is a large, flightless insect found above the treeline on many of the mountain ranges of the South Island of New Zealand. The population found on the Rock and Pillar Range, Central Otago has been identified as freezing tolerant with a haemolymph ice nucleating agent. The ability of H. maori to survive freezing is compared to the lowland weta Hemideina thoracica Walker and H. crassidens Blanchard, both of which are able to survive the formation of some ice in their bodies. Mortality is associated with time spent frozen in H. thoracica, and it is hypothesized that this species is killed when a critical proportion of its body water is frozen. All five subalpine and alpine populations of H. maori surveyed were found to be freezing tolerant. Comparison of temperatures of first nucleation and mean supercooling point of haemolymph droplets suggest that haemolymph ice nucleating activity varies between populations of H. maori. Hemideina maori collected from the Mt Cook region appear to lack a haemolymph ice nucleator. This population is nevertheless freezing tolerant, suggesting that the haemolymph ice nucleating agent described in H. maori is not essential for freezing tolerance. Hemideina crassidens and H. ricta Hutton, both of which are found in lowland habitats, also had high mean supercooling point and temperatures of first nucleation of haemolymph droplets, suggesting that these species also have a haemolymph ice nucleator. Comparison of ice nucleation characteristics of haemolymph and faecal material (representing gut contents) suggests that gut nucleators in H. maori may be at least as efficient as the haemolymph nucleator. It is concluded that freezing tolerance is probably not an adaptation to the alpine environment. This highlights the need for inter- and intraspecific comparative studies if physiological data are to be used to draw evolutionary conclusions.last_img read more

Red Bank’s Holiday Tree To Remain on Monmouth Street

first_imgBy John BurtonRED BANK — The tree isn’t going anywhere.A Red Bank RiverCenter proposal to relocate the borough’s holiday tree to Riverside Gardens Park hit a brick wall at the borough council meeting last week.Representatives for RiverCenter, the borough’s downtown business alliance, appeared before the mayor and council last Wednesday to discuss moving the tree from 30 Monmouth Street, where it has stood in the courtyard in front of the Dublin House Restaurant for the last few holiday seasons.The organization sponsors the annual tree lighting and concert that takes place each year on the day after Thanksgiving.RiverCenter’s Executive Director Nancy Adams said the park offered a more family friendly location for the tree and would be more visible there.Adams said she has received complaints from the public about the tree’s location “next to a bar” and the organization had been looking for an alternative site.Adams had attended a recent borough Special Events Committee, where she is a member, where the matter was broached, with Adams under the impression there was no opposition to it.But Borough Administrator Stanley Sickels disagreed. “There are a lot of issues that haven’t been discussed that have to be discussed,” about relocating the tree to the park, said Sickels, who also sits on the events committee.“It may not be an inexpensive proposition,” said Mayor Pasquale Menna.In order to move the tree to Riverside Gardens Park, West Front Street, the borough would have to install some infrastructure to secure it that could be kept covered the rest of the year, and would also need to be sure there is sufficient electrical power there to keep the tree lit, Menna noted, inquiring as to how that would be paid for and whether or not the logistics of moving the tree had been thoroughly considered.“What we really want to do is make the residents happy,” with an appropriate home for the decorated tree, Adams told the council.“You just can’t make a decision on limited facts,” Menna told Adams. “We may not have enough time.”“To be fair it was brought up a month ago,” at the last committee meeting, Adams responded.But the council seemed steadfast, with Council member Michael DuPont adding, “If you ask me my opinion, I think (Riverside Gardens Park) is a bad location.”Menna suggested RiverCenter consider putting the tree in front of 51 Monmouth Street, the former borough police headquarters and one time borough hall. The Community YMCA now owns it, but the borough maintains a volunteer fire company and the veterans’ memorial at the site.But for this year, at least, the tree will remain in its usual location on Monmouth Street.The tree lighting and concert are conducted each year, for about the approximately 20, on the Friday after Thanksgiving—“Black Friday” for retail merchants—to promote the downtown business district as a shopping location.Borough workers install the 2010 holiday tree outside the Dublin House on Monmouth Street.last_img read more

Unrepentant Pellegrini praises Man City youngsters

first_imgManchester City boss Manuel Pellegrini praised his young players after their 5-1 defeat at Chelsea in the FA Cup.Pellegrini fielded a vastly under-strength team, giving full debuts to five players in the fifth-round clash at Stamford Bridge.And they caused some problems for Chelsea before the hosts scored four times in the second half to clinch a quarter-final place.“In the first half we played very well and it was a very tight game,” Pellegrini said. “We played with six young players and I’m very happy with them.“It is important for young players to take their chance when they play, and I was very happy with that.“Unfortunately for us, in five minutes we threw away what we did and at 3-1 it was very difficult.“It is never good to lose 5-1, so I am not so happy about that. But there were a lot of positives.”Pellegrini, whose team play Dynamo Kiev in the Champions League on Wednesday, was unrepentant when asked about his team selection.“I always take the best decision for the club,” he said.See also:Hiddink praises players after Chelsea winChelsea thrash City to reach quarter-finalsChelsea v Man City player ratings’World class’ Hazard suffered dip in confidence – CahillFollow West London Sport on TwitterFind us on Facebooklast_img read more

Do not give your storage away

first_imgShare Facebook Twitter Google + LinkedIn Pinterest SoybeansBeans surprised everyone last week by rallying over $10. If exports remain strong, bean prices may stay at these levels. However, Gulf basis levels (export values) are at 10-year lows, these low basis levels often are an indicator that futures prices are too high longer term.Eyes are on South American weather as the summer approaches. Similar to last year for North America, there are drought/La Niña concerns going into summer, which are propping up prices. If La Niña does not develop, just like it didn’t in our growing season, then prices won’t likely stay at current levels. CornCorn continues to go nowhere and still is trading under $3.60. End users are mostly only buying immediate needs at these prices, waiting for prices to dip back below $3.40. Farmers, on the other hand, are largely waiting for better prices, because in recent years they have been rewarded for holding.There’s been some action in corn basis throughout the Midwest at ethanol plants and feed mills. Some of this is due to smaller end users not getting as much corn as expected during harvest. Maybe holding the corn will reward the farmers again.Do not give your storage awayIn order for farmers to get bigger premiums and profits out of the market, farmers need to think about grain marketing differently than the “common” or “conventional” wisdom. This is especially true in years when grain prices are close to breakeven points. The following is an example of a common mistake I see among farmers that don’t have 100% on-farm storage.Usually I see farmers make sales for Dec or Jan delivery as their first and only sale before harvest. Often they do this to get the market carry as a premium. Most farmers do this because conventional wisdom says farmers need to core out their bins then, so selling some grain makes sense. However, this wisdom is only true for farmers with 100% on-farm storage and the wrong thing to do for those that do not. Let me explain.In June, corn prices for December delivery were $4.40, while harvest delivery was $4.30. Basically, it means there was a 10-cent premium to hold the grain for two months after harvest, or about five cents per month. Many farmers that don’t have 100% on-farm storage know they still need to core their bins sometime in the winter. That is why they originally sold for December delivery to capture the carry, thinking they were getting the best deal. However, these farmers still have to deliver grain at harvest because of their lack of storage. Today the market is under $3.60 and many farmers don’t want to sell their grain at these levels. So, they will pay storage fees at their commercial facility, which are likely at five cents per month, waiting until prices go up.Farmers that tried to capture the carry early will wipe away all the profits from the original trade waiting for better prices on the unpriced grain in commercial storage. Many wind up paying around 30 cents to store grain until the spring. By doing this, the 10-cent premium on the grain they sold first will eventually be wiped away, creating a net loss of 20 cents on their marketing program. Most farmers are too focused on cash prices and not paying attention to expenses of storage.I understand the need to core bins in the winter. Farmers that are trying to take advantage of the market carry for Dec delivery makes some sense. However, farmers really could wait until the end of January or even February to core bins. If they were to do this, it would give them an extra two months’ worth of free storage in their own bins at home. This would allow for a longer time period for prices to move and possibly basis levels to improve. Thus a farmer doesn’t give away any storage.It’s difficult for farmers without 100% on-farm storage to estimate how much storage they will need each year. This is why I like to use futures — it gives me the flexibility to decide when, where, and how much grain I want to move at harvest or the middle of winter. I can still pick up the 10 cents of carry once I’m done harvesting. Flexibility in your grain marketing strategy (and sometimes going against “conventional wisdom”) will lead to increased profitability.Jon grew up raising corn and soybeans on a farm near Beatrice, NE. Upon graduation from The University of Nebraska in Lincoln, he became a grain merchandiser and has been trading corn, soybeans and other grains for the last 18 years, building relationships with end-users in the process. After successfully marketing his father’s grain and getting his MBA, 10 years ago he started helping farmer clients market their grain based upon his principals of farmer education, reducing risk, understanding storage potential and using basis strategy to maximize individual farm operation profits. A big believer in farmer education of futures trading, Jon writes a weekly commentary to farmers interested in learning more and growing their farm operations.Trading of futures, options, swaps and other derivatives is risky and is not suitable for all persons.

Uber used tech tool to shield data from police outside US

first_imgNEW YORK, N.Y. – The ride-sharing company Uber confirmed Thursday that it had technology to shield company data when law enforcement raided its offices outside the U.S.Uber spokeswoman Melanie Ensign said this tool — no longer in use — could lock computers and smartphones and change passwords remotely from the company’s headquarters in San Francisco.Bloomberg reported Thursday that Uber used the tool, known as Ripley, from spring 2015 until late 2016 in several cities, including Paris, Hong Kong, Brussels, Amsterdam and Montreal.Bloomberg said some Uber employees felt the system hindered legitimate investigations, while some people believed its use was justified when police didn’t come with warrants or specific-enough data requests.The use of this tool raises questions for Uber because the company has in the past used a phoney version of its app to thwart authorities. The “Greyball” software identified regulators who were trying to hail a ride in an attempt to collect evidence of local law-breaking. Those rides would be cancelled or never arrive. It has also been reported that the Justice Department was investigating whether Uber illegally used software to track drivers of its rival Lyft.Bloomberg reported that authorities in Montreal were seeking evidence in May 2015 that Uber had violated tax laws. Uber’s use of Ripley meant they didn’t get any information, but Uber co-operated with a second search warrant and agreed to collect provincial taxes for each ride, Bloomberg said.Ensign said the company shut down Ripley in 2016 because it didn’t work well.She said Uber now has a tool called ULocker that can remotely lock and encrypt devices. Ensign could not immediately say if Uber has used that to protect data from law enforcement as well. But she said Uber’s guidance to employees bars use of the tool where it isn’t legal.In a statement, Uber said this security tool is similar to those used by other companies and gives Uber a way to block access to data when an employee loses a device. The company said its policy is to co-operate with “all valid searches and requests for data.”The ride-hailing service had a scandal-ridden 2017 that included lawsuits, government probes, the revelation of a significant sexual-harassment problem and the disclosure of a coverup of a hack that stole personal information of 57 million passengers and 600,000 drivers. The company’s hard-charging CEO, Travis Kalanick, resigned in June and was replaced in August by the former CEO of Expedia, Dara Khosrowshahi.last_img read more

Ethnicdiversity is Frances strength feel its football officials

first_imgLille (France): People occupying high offices in French football are firm believer of ‘Black, Blanc, Beur’, a phrase often used to celebrate the ethnically-diverse national team’s 1998 World Cup triumph and the one last summer. Black is black, Blanc means white and Beur Arabic, implying that the players stay united on the field, irrespective of their origins and religions. People in high places believe that the French society is as accepting as its national team, ignoring the right-wing voices’ sporadic outbursts against the country’s immigration policies. Also Read – Puducherry on top after 8-wkt win over ChandigarhFootball took them from the streets of Paris’ banlieues (suburbs) to the stadiums of Russia and when the likes of Kylian Mbappe and Paul Pogba flew back with the glittering World Cup trophy in their hands, it was hailed as the triumph of France’s immigrants. “Immigration is not an issue, immigration is a chance, and we have big players from Africa. It is a chance for France to develop football. Mbappe is French. France is known for its acceptance, accepting people from all over, including Africa. It’s France’s strength,” said Didier Quillot, CEO of Ligue de Football Professional (LFP), which runs the country’s major leagues. Also Read – Vijender’s next fight on Nov 22, opponent to be announced laterWhile its national team is looked at as a symbol of its multiculturalism, the country is often divided over the issue of refugees. France’s last major triumph was attributed to the efforts of a diverse, multicultural group of players. In the 23-member World Cup squad, 17 were immigrants or the children of immigrants. It comprised players of African and Arab descent, reviving memories of the 1998 World Cup triumph. Headlines such as ‘Triumph of Africa’ and ‘The last African team’, after the team’s win in Russia, left Paris Saint-Germain’s communications director, Jean-Martial Ribes, surprised. “The French people don’t think that they are African or Arabic. For us they are all French. France is known for its diversity, something like the USA. We were a little bit surprised to see the comments in some of the media. “Perhaps that’s what makes France a better place. People from every origin are welcome here and accepted. Our focus was on the triumph,” Ribes said.Chelsea legend Didier Drogba, who is presently a brand ambassador of Coupe de la Ligue, said there is no place for racism and exclusion in football “I feel people are focusing on France but this (immigration) is a general problem in all society right now. People speak about discrimination and all but this has no place in football. Football is a place where we try to include everyone. Football has the power to unite more than anything else,” Drogba said. The former Ivory Coast striker added, “When you look very closely at the teams, the players, the stars you will not see discrimination. Most of the time it’s the people coming to the game from outside who bring that. People from outside, politicians do that. But inside it’s different.” Though the players of African or Arab origin in France have often been questioned over their allegiance to the flag.last_img read more

Australia sees record temperatures for fourth month in a row Report

first_imgSydney: Australia continued a string of “hottest ever” months in March, the government said Monday, as global warming emerges as the hot button issue in national elections just weeks away. The Bureau of Meteorology (BOM) said the country had experienced the warmest March on record, with mean maximum and minimum temperatures above average for nearly all of the vast continent nation. BOM said the national mean temperature was 2.13 degrees centigrade (3.83 degrees Fahrenheit) above the long-term average for the month of March.

There was some relief for regions suffering from prolonged drought, however, as two tropical cyclones that struck northern and western Australia in March bought badly needed rains. “Unfortunately, the rain needed to reduce significant rainfall deficiencies in drought-affected areas is substantial and will require above average rainfall over a prolonged period to completely remove deficits at longer timescales,” BOM said. Also Read – Record number of 35 candidates in fray for SL Presidential pollsMeteorologists say weather patterns over the Indian and Pacific oceans have contributed to the higher temperatures, but that long-term climate change trends were also involved. The problem of climate change has emerged as a key issue in national elections due to be held by mid-May. The conservative coalition government of Prime Minister Scott Morrison has been reluctant to back steep reductions in greenhouse gas emissions blamed for contributing to global warming for fear this would hurt the country’s huge coal industry and undermine economic growth.last_img read more
