Transport of antarctic krill (Euphausia superba) across the Scotia Sea. Part II: Krill growth and survival

first_imgA time-dependent, size-structured, physiologically based krill growth model was used in conjunction with a circulation model to test the hypothesis that Antarctic krill (Euphausia superba) populations at South Georgia are sustained by import of individuals from upstream regions. Surface phytoplankton concentrations along the simulated drifter trajectories were extracted from historical Coastal Zone Color Scanner (CZCS) measurements and sea ice biota concentrations were calculated from sea ice concentration and extent extracted along drifter trajectories from Special Sensor Microwave/Imager measurements. As additional food sources, a time series of heterotrophic food was constructed from historical data, and time series of detritus concentrations were calculated using phytoplankton concentrations extracted from CZCS measurements together with measured particulate organic carbon to chlorophyll a ratios. These food resources along specified drifter trajectories were then input to the krill growth model to determine the size and viability of krill during transport from the source region to South Georgia. The krill growth model simulations showed that no single food source can support continuous growth of krill during the 58–306 days needed for transport to South Georgia. However, under the current assumptions results indicate that combinations of food sources during the transport time enhanced krill survival, with heterotrophic food and detritus being particularly important during periods of low phytoplankton concentrations. The growth model simulations also showed that larval and juvenile krill originating along the western Antarctic Peninsula can grow to 1+ (14–36 mm) and 2+ (26–45 mm) age and size classes observed at South Georgia during the time needed for transport to this region. Krill originating in the Weddell Sea need 20 months for transport, which allows retention in a potentially high food environment, provided by sea ice, for almost 1 year. Krill then complete transport to South Georgia in the following year and larval and juvenile krill grow to 2+ (26–45 mm) and 3+ (35–60 mm) age and size classes during transport. The results of this study show that the successful transport of krill to South Georgia depends on a multitude of factors, such as the location of the spawning area and timing of spawning, food concentrations during transport, predation, and variations in the location of the Southern Antarctic Circumpolar Current Front (SACCF) and in sea ice extent.last_img read more

Oxford City Council launch new provision to tackle homelessness

first_imgExpert assessment and reconnection workers will help people to develop personal housing plans and get the support they need from other services to move quickly into more sustainable accommodation.” She added: “I’m really pleased that St Mungo’s are operating the new service and the winterlong shelter available to anyone experiencing homelessness will open in early November. Their experience of running this type new assessment service in London and the South of England has seen four fifths of people leaving the streets behind for good. Councillor Linda Smith, deputy leader and cabinet member for leisure and housing, said: “It takes more than a roof to end homelessness and Somewhere Safe to Stay is the first stage in our plans to transform services for people experiencing homelessness in Oxfordshire.” Beds will also be made available for 15 people at a new winter shelter by the beginning of November, which will be open to anyone in need, regardless of local connections. Both services will be operated by St. Mungo’s, one of the largest providers of outreach services in the country. Oxford City Council have announced a new provision designed to tackle homelessness. The scheme, known as the ‘Somewhere Safe to Stay’ service, will provide beds for 12 people experiencing homelessness for up to 7 nights. Until the council has established its permanent hub at 1 Floyds Row in January, ‘Somewhere Safe to Stay’ will be operating out of Simon House. “This fundamental change to front end homelessness services and winter accommodation will help us to achieve this and be a catalyst for change across the wider system.” New action on homelessness is part of the Rough Sleeping Strategy, a recent effort launched by the government in order to alleviate Britain’s homelessness problem. Oxford City Council is one of 42 early adopters who were allocated funding for 2019/2020. “We believe that nobody should have to sleep rough in Oxford and the best way to help someone experiencing rough sleeping is to get them to come inside and find the support they need to rebuild their lives. Statistics from Oxford City Council esti- mated that 51 people were sleeping rough in September 2019, a 42% increase from September 2018. Over a quarter of those surveyed had been homeless for less than six months or were newly verified by the count. The hub will also offer thorough assessments to the users, linking them with support services and suitable housing. It is aimed specifically at those who are newly homeless, in the hopes that providing early support will prevent chronic homelessness. Oxford City Council is involved in numerous new initiatives to tackle homelessness, including the Oxford Homeless Movement, which launched earlier this month and is a partnership between numerous homelessness organisations in the city.last_img read more

l This letter was sent on 1 November to the Prime Minister – the NAMB is awaiting a reply.

first_imgDear Mr CameronThe NAMB represents craft bakers’ businesses in England, Wales, Northern Ireland and the Channel Islands and, on their behalf, I am completely appalled at the information in today’s news.Was it on Tuesday, Mr Prime Minister, that you stood before the CBI to encourage businesses (large and small) to lead the country out of its economic turmoil? Then yesterday, your colleague, the Pensions Minister, announced a new employer’s pension contribution, staged from 2012 of 1% to 3% from 2017.What a contradiction over a 24-hour period! Surely this has to be a massive disincentive for our members to increase full-time employees. In fact, I see this as an increase of NI contributions of 1%-plus, that you and your colleagues so rightly pilloried the last Labour Government over.All these ideas may seem right in Westminster circles, but are clearly unaffordable for small businesses being squeezed from all angles. Bakers cannot increase prices at the drop of a hat to maintain their margins and the result will be more redundancies.You have time for a rethink please consult associations like mine, where you could find alternative suggestions from the people who voted you into office.last_img read more

Discovering predictor for fatal infection in preterm babies

first_imgAs a Neonatal Intensive Care Unit (NICU) nurse in the late 1990s, Katherine Gregory was both concerned and curious about necrotizing enterocolitis (NEC), a sometimes fatal infectious disease of the newborn gut affecting preterm infants.The condition, one of the most serious complications of preterm birth, can cause severe infection, neurodevelopmental impairment, intestinal perforations, malnutrition, prolonged hospitalization, and even death.The most challenging aspect of treating newborns with NEC was the vague and nonspecific signs and symptoms prior to its onset. Gregory and her NICU colleagues at Harvard-affiliated Brigham and Women’s Hospital (BWH) knew that once the symptoms manifested, the disease could be at an advanced stage and progress quickly.“I would care for babies who survived the early stages of prematurity and seemed to be faring well, who would suddenly become catastrophically ill,” recalled Gregory.Gregory’s work in the NICU prompted her to launch a research project that examined the physiology and pathological processes related to NEC, searching for a biomarker (a biological substance that indicates the presence of a disease or a pathogen). The predictor would enable clinicians to better anticipate, diagnose, and prevent the condition.“The NICU team caring for preterm infants needed to be able to measure something that would give us a warning sign that the disease was imminent so we could be better prepared,” said Gregory, now a senior nurse scientist at BWH, who has devoted her career to researching gastrointestinal health and disease in newborns.In collaboration with a multidisciplinary research team, Gregory successfully measured a biomarker for NEC called intestinal fatty acid binding protein (iFABP), a protein specific to intestinal inflammation and injury. She found that elevated levels of iFABP appeared in urine three and seven days before the onset of NEC symptoms. In 2014, her research was published in The Journal of Pediatrics.“We have made some progress toward understanding NEC,” said Gregory. “However, this disease remains a major contributor to morbidity and mortality for preterm infants, so we have more work to do,” she added.To read the full story and additional research being done by Gregory and her colleagues, visit BWH Clinical and Research News.last_img read more

Border ID changes coming June 1

first_imgWith new border crossing requirements coming on June 1, state officials are urging businesses to get enhanced identification cards for employees who regularly travel to Canada. Starting June 1, the federal Western Hemisphere Travel Initiative (WHTI) will require WHTI-approved documents for entry to the United States. That means that most U.S. citizens entering the United States by sea or land will need a passport, passport card, or WHTI-compliant document like a Vermont Enhanced Drivers License (EDL). According to Canadian government statistics for 2007, 17,500 Vermont jobs are supported by Canada–U.S. trade and Canadians made more than 765,900 visits to Vermont that year, spending $148 million here, while Vermont residents made 148,200 visits to Canada, spending $56 million.“In business, time is money,” said Kevin Dorn, Vermont Secretary of Commerce and Community Development. “An Enhanced Drivers License or Enhanced Non-Driver ID can cut down on delays in crossing the border with Canada.”“Our largest trading partner, as well as one of the most popular destinations for Vermont tourists, is Canada, specifically Quebec,” Dorn said. “An EDL makes travel to Canada much easier whether for business or pleasure.”Only Vermont residents who are also U.S. citizens are eligible to apply for an Enhanced Drivers License or ID card, and at this time they are only available at the Montpelier Department of Motor Vehicles office.An EDL/ID costs $25 in addition to the standard fees for licenses or non-driver IDs, and license fees vary by class, duration, and endorsement. A standard 4-year operator license is $40, so an Enhanced 4-year operator license would be $65.DMV staff will determine eligibility for an EDL/ID by verifying the information on the source documents submitted and conducting investigative applicant interviews to determine identity and citizenship.Obtaining an Enhanced Drivers License or ID will require, at a minimum, presentation and verification of a photo identity document; documentation showing the applicant’s date of birth; proof of the person’s social security number; and documentation showing the applicant’s name and address of principle residence.Officials from the DMV advised Vermonters to consult the department’s website and make sure they have the documentation needed.“We have had instances of people being turned away because they didn’t have the required paperwork,” said DMV Commissioner Bonnie Rutledge. “Since the process of verifying the documentation can take up to 20 minutes, waits at the DMV are a little longer and we don’t want people to spend that time waiting only to find out they don’t have proper identity documents.”last_img read more

Commentary: Trans Mountain Financial Problems Are Kinder Morgan’s Issue, Not Canada’s

first_imgCommentary: Trans Mountain Financial Problems Are Kinder Morgan’s Issue, Not Canada’s FacebookTwitterLinkedInEmailPrint分享National Observer:In an unusual action for a Sunday afternoon, on April 8, 2018, Kinder Morgan Canada Limited (KML) issued a press release announcing it had taken the Trans Mountain pipeline expansion project hostage. The company said it was suspending “all non-essential activities and related spending” on the project.The demands? Meet two conditions by May 31 or Trans Mountain’s expansion would die. The two conditions? Final clarity on its ability to construct the project through B.C. and adequate protection of KML shareholders.Kinder Morgan’s fanfare announcement is a cover-up. Trans Mountain pipeline expansion lacked commercial viability from the get-go. It has required government supported handouts at every stage of development. Kinder Morgan has put very little shareholder capital at risk. It has always looked to others— the shippers, Canadian investors and Canadian taxpayers — to do so.Upside potential with none of the downside risk is a sweet deal. The Texas-based company — forged from the executive ranks that ran Enron — wants to keep it that way.Kinder Morgan’s shareholders have almost nothing at risk — somewhere around $200 million. Sure, project spend to date is $1.1 billion but Kinder Morgan has confirmed these costs are reduced by $210 – $220 million through the Firm 50 Fund granted to the company in an unprecedented [National Energy Board] approval in 2011. Further, the early termination clause 5.4(b)(i)(A) in Kinder Morgan’s contract with long-term take or pay shippers means oil companies pick up 80 per cent of costs. So, Kinder Morgan’s shareholders are exposed to only about 20 per cent of the $900 million — or roughly $200 million.For Kinder Morgan to proceed it will likely want Ottawa to protect its shareholders from exposure beyond what they now have at stake. The “adequate protection of shareholders” Kinder Morgan seeks, when Kinder Morgan has almost no skin in the game, is a very expensive proposition for Canadian taxpayers on a go forward basis.More: What’s Behind Kinder Morgan’s May 31 Ultimatum?
