The compound effects of changing habitats, ecosystem interactions, and fishing practices have implications for the management of Antarctic krill and conservation of its predators. For Antarctic pack-ice seals, an important group of krill predators, we estimate the density and krill consumption in the West Antarctic Peninsula (WAP)–Western Weddell Sea area, the main fishery region; and we consider long-term changes in suitable pack-ice habitat, increased fishing pressure and potential krill declines based upon predictions from declines in sea ice cover. More than 3 million crabeater seals consumed over 12 million tonnes of krill each year. This was approximately 17% of the krill standing stock. The highest densities of pack ice seals where found in the WAP, including in its small-scale fishery management areas, where apparently suitable seal habitat has declined by 21–28% over a 30 year period, where krill density is likely to have declined, and fishing has increased. The highest seal density was found in the Marguerite Bay area which is a source of krill for the Antarctic Peninsula and elsewhere. Significant sea-ice loss since 1979 has already occurred, leading to open water and possible expansion for the fishery in the future. These factors may combine to potentially reduce food for pack ice seals. Therefore, high uncertainty in krill and seal stock trends and in their environmental drivers call for a precautionary management of the krill fishery, in the absence of survey data to support management based on specific conservation objectives for pack-ice seals.
Independent 5 February 2017Family First Comment: It just gets worse!And add to that…..“The Dutch Parliament is considering revising the euthanasia laws to allow anyone older than 75 who is “tired of life” to have the right to assisted suicide, widening the current restriction which limits the practice to the terminally ill.”A Dutch doctor who ordered an elderly dementia patient’s family to hold her down as she was given a lethal euthanasia injection has been cleared of any wrongdoing.The doctor at a nursing home in the Netherlands, where euthanasia is legal, was investigated following the death of the unnamed woman who had expressed a wish to die “when the time was right”.The Catholic News Agency reported that the woman woke up despite the sleep-inducing drug she had been given in her coffee and tried to resist the procedure.The doctor then asked the relatives of the woman, said to be aged “over 80”, to restrain her while she administered the lethal injection.The senior doctor had determined the time was right because of a recent deterioration in the woman’s condition.“I am convinced that the doctor acted in good faith, and we would like to see more clarity on how such cases are handled in the future,“ said Jacob Kohnstamm, chairman of the Regional Review Committee, which considered the case.The case will be further examined by the Dutch courts to clarify the laws around euthanasia and determine whether doctors who carry out the procedure should be prosecuted if they are found to have acted in good faith.The Dutch Parliament is considering revising the euthanasia laws to allow anyone older than 75 who is “tired of life” to have the right to assisted suicide, widening the current restriction which limits the practice to the terminally ill.The Netherlands was the first country in the world to decriminalise euthanasia and assisted suicide in 2002, but has had several high-profile cases of doctor-assisted suicide in recent years.In 2015, there were more than 5,000 euthanasia deaths in the country – which represents a leap of 50 per cent in the past five years. Only four of these 5,306 deaths were found by officials to have involved “irregularities”. Psychiatric patients can be put to death at their own request as can under 18s. Those aged between 12 and 16 wishing to die must also have the consent of their parents, but 16-18s can take the decision themselves.READ MORE: http://www.independent.co.uk/news/world/europe/doctor-netherlands-lethal-injection-dementia-euthanasia-a7564061.html
Simona Halep lost the top ranking after Naomi Osaka won Australian Open.Simona Halep could face Venus Williams in Miami Open.Andre Agassi has won most Miami Open titles with six. Djokovic moved 5-2 ahead but after he missed a set point opportunity on the Delbonis serve, his game deserted him and suddenly, the South American had a spring in his step. Delbonis had opportunities to steal ahead, yet calling on all his experience and mental resolve, the Serbian was able to hold firm and take the opener. The world number one was getting incredibly frustrated , he received a warning for racquet abuse and was furious for allowing a 3-1 lead to slip in the second, yet credit to Delbonis who stayed calm and served out confidently to force a decider, something which looked beyond him midway through the opening set. He couldn’t keep the pressure on, however, and when Djokovic managed to get 3-1 ahead, this time there was no way back for the 28 year-old from Azul who rightly received an ovation from the center court crowd for his monumental efforts. “I think last four games were terrific, so I ended up in a positive way,” Djokovic added. Defending champion John Isner blew Spain’s Albert Ramos-Vinolas off court with serves touching 139 mph as the American sealed an ultimately comprehensive 7-5, 7-6 (8-6) win to set up an intriguing match with Kyle Edmund in the last 16 after the British number one impressively saw off Canadian Milos Raonic 6-4 6-4. In the women’s draw, Simona Halep kept alive hopes of regaining the world number one ranking Sunday, beating Polona Hercog 5-7, 7-6 (7/1), 6-2 to reach the last 16 where she will play Venus Williams. Halep, 27, lost her place at the top of the rankings following Naomi Osaka’s triumph at the Australian Open earlier this year. But with the Japanese faltering here on Saturday, Halep can return to the position she last held at the end of 2018 if she lands the Miami Open for the first time.”It’s always tough against Venus,” said the current world number three, who has beaten the American in their previous three encounters. “I’m not going to say that it’s going to be easier because I won the last matches against her. It’s a big challenge for me.” Seven-time Grand Slam champion Williams, meanwhile, swept past Russian Daria Kasatkina 6-3, 6-1. “Simona always plays flawless tennis against me, so I have to be ready for that,” Williams said. Elsewhere in women’s action, American Sloane Stephens’s title defense ended in a 6-3, 6-2 loss to Germany’s Tatjana Maria. It was another disappointing ending for Stephens, who fell in the third round at Indian Wells. Miami: Novak Djokovic remains on course for a record seventh Miami Open title, but the world number one admitted to a loss of focus in a 7-5, 4-6, 6-1 victory over spirited Federico Delbonis which booked his place in the last 16. Djokovic is hoping to eclipse Andre Agassi’s six ATP crowns in South Florida over the next week and although the 31-year-old endured some shaky moments at Hard Rock Stadium, he still possessed enough quality during the key moments to see off the battling Delbonis. The Serbian, though, wasn’t happy with letting a 5-2 advantage slip in the first set and became furious with himself as the second squirmed from his grasp. He will need to tighten up his game if he is to reach next Sunday’s final with Roberto Bautista Agut waiting in the fourth round after the Spaniard defeated Italian Fabio Fognini 6-4, 6-4. “To be honest, I lost my focus,” said Djokovic who smashed 36 winners compared to 24 from Delbonis. “I should have done better I think mentally than I have done at the end of the first two sets. “I managed to really play well last couple games of first set, go up a break, put myself in front, then I played a couple of really bad service games. Credit to Federico, he stepped in.” Djokovic had looked impressive in the second round win over Bernard Tomic and the Serbian continued his decent form by immediately imposing himself onto the Argentine. highlights For all the Latest Sports News News, Tennis News News, Download News Nation Android and iOS Mobile Apps.
