At Bird Island, South Georgia, we surveyed the distribution and abundance of ticks on the vertebrate fauna and found only 1 species Ixodes uriae. We classified all seabird species into 3 groups: (1) seabirds nesting on the surface of the ground solitarily, in dispersed groups of a few nests, or in colonies with well-spaced nests; (2) seabirds nesting on the surface of the ground in dense colonies; and (3) seabirds nesting in dense colonies in burrows or rock crevices. We detected I. uriae only on 3 species of the second group that nested in large, dense, persistent colonies, i.e., black-browed albatross (Diomedea melanophrys), gray-headed albatross (Diomedea chrysostoma), and macaroni penguin (Eudyptes chrysolophus). Ticks were found on the undersides of the feet on albatrosses but not on the undersides of the feet on penguins. We hypothesize that the coarse pebble nests of penguins, combined with the fact that their young walk around more than albatross young, make the environment on the underside of penguin feet more harsh and hostile for ticks than the underside of albatross feet. Despite the great abundance of Antarctic fur seals (Arctocephalus gazella) on the island, we found no ticks on them.
Our current understanding of Antarctic soils is derived from direct culture on selective media, biodiversity studies based on clone library construction and analysis, quantitative PCR amplification of specific gene sequences and the application of generic microarrays for microbial community analysis. Here, we investigated the biodiversity and functional potential of a soil community at Mars Oasis on Alexander Island in the southern Maritime Antarctic, by applying 454 pyrosequencing technology to a metagenomic library constructed from soil genomic DNA.The results suggest that the commonly cited range of phylotypes used in clone library construction and analysis of 78–730OTUs (de-replicated to 30–140) provides low coverage of the major groups present (s5%). The vast majority of functional genes (>77%) were for structure, carbohydrate metabolism, and DNA/RNA processing and modification. This study suggests that prokaryotic diversity in Antarctic terrestrial environments appears to be limited at the generic level, with Proteobacteria, Actinobacteria being common. Cyanobacteriawere surprisingly under-represented at 3.4%of sequences, although s1% of the genes identified were involved in CO2 fixation. At the sequence level there appeared to be much greater heterogeneity, and this might be due to high divergence within the relatively restricted lineages which have successfully colonized Antarctic terrestrial environments.
Efforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland ice sheet to the warmer-than-present climate of the Eemian has thus remained unclear. Here we present the new North Greenland Eemian Ice Drilling (‘NEEM’) ice core and show only a modest ice-sheet response to the strong warming in the early Eemian. We reconstructed the Eemian record from folded ice using globally homogeneous parameters known from dated Greenland and Antarctic ice-core records. On the basis of water stable isotopes, NEEM surface temperatures after the onset of the Eemian (126,000 years ago) peaked at 8 ± 4 degrees Celsius above the mean of the past millennium, followed by a gradual cooling that was probably driven by the decreasing summer insolation. Between 128,000 and 122,000 years ago, the thickness of the northwest Greenland ice sheet decreased by 400 ± 250 metres, reaching surface elevations 122,000 years ago of 130 ± 300 metres lower than the present. Extensive surface melt occurred at the NEEM site during the Eemian, a phenomenon witnessed when melt layers formed again at NEEM during the exceptional heat of July 2012. With additional warming, surface melt might become more common in the future.
Two decades into the 21st century there is growing evidence for global impacts of Antarctic and Southern Ocean climate change. Reliable estimates of how the Antarctic climate system would behave under a range of scenarios of future external climate forcing are thus a high priority. Output from new model simulations coordinated as part of the Coupled Model Intercomparison Project Phase 6 (CMIP6) provides an opportunity for a comprehensive analysis of the latest generation of state‐of‐the‐art climate models following a wider range of experiment types and scenarios than previous CMIP phases. Here the main broad‐scale 21st century Antarctic projections provided by the CMIP6 models are shown across four forcing scenarios: SSP1‐2.6, SSP2‐4.5, SSP3‐7.0 and SSP5‐8.5. End‐of‐century Antarctic surface‐air temperature change across these scenarios (relative to 1995–2014) is 1.3, 2.5, 3.7 and 4.8°C. The corresponding proportional precipitation rate changes are 8, 16, 24 and 31%. In addition to these end‐of‐century changes, an assessment of scenario dependence of pathways of absolute and global‐relative 21st century projections is conducted. Potential differences in regional response are of particular relevance to coastal Antarctica, where, for example, ecosystems and ice shelves are highly sensitive to the timing of crossing of key thresholds in both atmospheric and oceanic conditions. Overall, it is found that the projected changes over coastal Antarctica do not scale linearly with global forcing. We identify two factors that appear to contribute: (a) a stronger global‐relative Southern Ocean warming in stabilisation (SSP2‐4.5) and aggressive mitigation (SSP1‐2.6) scenarios as the Southern Ocean continues to warm and (b) projected recovery of Southern Hemisphere stratospheric ozone and its effect on the mid‐latitude westerlies. The major implication is that over coastal Antarctica, the surface warming by 2100 is stronger relative to the global mean surface warming for the low forcing compared to high forcing future scenarios.

Beau Lund Written by November 10, 2018 /Sports News – National In a first for Iran, hundreds of women attend a major soccer match in Tehran FacebookTwitterLinkedInEmailAmin M. Jamali/Getty Images(NEW YORK) — After a nearly forty-year ban, hundreds of Iranian women were allowed to attend an international soccer final at a stadium in Tehran on Saturday, where they managed to secure nearly one percent of the seats at Azadi Stadium.Saturday’s event — the Asian Champions League final pitting an Iranian team known as Persepolis against a Japanese squad called the Kashima Antlers — saw the most significant female presence at a top soccer match in Iran since the Islamic revolution in the late 1970s.Iranian conservatives have persistently been opposed to women attending live sports matches, but cultural pressure has been steadily building against the ban.“It is time to let women in,” said Reza, 45, a real estate employee who was trying to find a ticket to enter the stadium. “We are fed up with so much economic pressures. We all need fresh air,” the woman, who declined to provide her last name, said.Reformists and women’s rights activists have been pushing for opening the doors to stadiums for years. Besides, pressures from international bodies seeking Iran’s compliance with their required equality standards have occasionally forced Iranian authorities to let at least a small group of women in.The practice invited widespread criticism by social media users who alleged that there were select groups of women attending the stadium to fulfill international expectations, an allegation denied by authorities.“I prefer watching nonsense soap operas than Persepolis and Kashima’s match with this way of selecting the spectators,” wrote Samira Alampanah on her Twitter.Waiting outside the doors about three hours before the match, Yalda, 28, said “we want to get in for Persepolis.”“So, it will have some real fans on the seats, not just the select group allowed in to appease FIFA and AFC,” she said, referring respectively to the international and Asian governing bodies of professional soccer, the Fédération Internationale de Football Association and the Asian Football Confederation. Outside the U.S, soccer is known as football.But Yalda’s path was tougher than she had imagined. She and a group of about 200 fans had to pass three gates before entering the stadium — each one of which kept their hopes of getting in hanging in the balance.Ironically, some of the women reported, the officials at each gate were as uncertain as women themselves.“I’ve been told ten times to go home and watch the match on TV, and then another official comes and says ‘there is still hope,’” said Mahsa Taheri, 27, an accountant who decided to skip a day at work once she heard that women would be allowed in.“I’m here to stay,” she said.After several hours of waiting, the gates were eventually opened for Yalda and others. A security official who requested anonymity told ABC News that Fariba Mohammadian, Iran’s Women’s Deputy Minister of Sports, helped exhausted and intimidated female fans into the stadium.But, by the time the women got inside, the section of about 850 seats allocated to females was almost full. Despite being on their feet at the gates for hours, the newly-arrived fans started to cheer their team, many shedding tears of joy.“I am proud that we insisted so much, leaving no way for the officials but to compromise to some extent,” said Maral, 42, who had come to watch the game with her sisters and her cousin. “We want our team to know that everyone supports them, not just men.”In a note published on FIFA’s website, FIFA president Gianni Infantino said it was “a historic and festive day for football, a real breakthrough.”Infantino thanked Iranian President Hassan Rouhani for paving the way for the women’s attendance at the stadium.“This is the power of football and makes it all worthwhile!”Once allowed in, some fans burst into tears of joy which were subsequently supplanted by tears of disappointed fans.Persepolis lost the final to its Japanese rival.“One thing I am sure is that we will definitely come again,” Maral said.“We know that there will be gates on the way, but we hope it gets easier to get in.”Copyright © 2018, ABC Radio.
