Digenean, monogenean and cestode infection of inshore fish at the South Orkney Islands

first_imgNotothenioid fish of 3 species – 23 immature Notothenia coriiceps, 4 Gobionotothen gibberifrons and 11 Chaenocephalus aceratus, from the coastal zone at the South Orkney Islands were examined to determine their parasite infection. Five digenean species from the intestine, one monogenean species from the skin, two tetraphyllidean larval forms (cercoids) from the intestine, and diphyllobothriid plerocercoids from the stomach’s wall, liver and body cavity are reported. Infections are compared with those of fish from adjacent island groups along the Scotia Arc. Parasite infections of the fish from the South Orkney Islands were more similar to those at the South Shetland Islands area than at South Georgia. The infection of N. coriiceps and G. gibberifrons is similar to that of fjord fish at South Georgia and the South Shetland Islands, whereas the parasite burden of Ch. aceratus was more similar to that of this fish species inhabiting the open sea.last_img read more

Widespread low rates of Antarctic glacial isostatic adjustment revealed by GPS observations

first_imgBedrock uplift in Antarctica is dominated by a combination of glacial isostatic adjustment (GIA) and elastic response to contemporary mass change. Here, we present spatially extensive GPS observations of Antarctic bedrock uplift, using 52% more stations than previous studies, giving enhanced coverage, and with improved precision. We observe rapid elastic uplift in the northern Antarctic Peninsula. After considering elastic rebound, the GPS data suggests that modeled or empirical GIA uplift signals are often over-estimated, particularly the magnitudes of the signal maxima. Our observation that GIA uplift is misrepresented by modeling (weighted root-mean-squares of observation-model differences: 4.9–5.0 mm/yr) suggests that, apart from a few regions where large ice mass loss is occurring, the spatial pattern of secular ice mass change derived from Gravity Recovery and Climate Experiment (GRACE) data and GIA models may be unreliable, and that several recent secular Antarctic ice mass loss estimates are systematically biased, mainly too highlast_img read more

Interpreting empirical estimates of experimentally derived physiological and biological thermal limits in ectotherms

first_imgWhole-organism function is underpinned by physiological and biological processes, which respond to temperature over a range of time scales. Given that environmental temperature controls biological rates within ectotherms, different experimental protocols are needed to assess the ability of organisms to withstand extreme weather events versus gradual temperature change. Here we emphasize the importance of time in shaping ecological and evolutionary processes, and as an experimental parameter that is key when interpreting physiology studies reporting thermal limits. We discuss how acute and chronic thermal performance is underpinned by mechanisms operating at different time scales-resistance, acclimation, and adaptation. We offer definitions of common physiological and biological temperature metrics and identify challenges inherent to compiling the wealth of historical temperature limit data now available into meta-analytic frameworks. We use a case study, data across temperate fishes, to highlight that false positives may occur when differences in the thermal tolerances of species are in fact due to experimental protocols. We further illustrate that false negatives can arise if researchers fail to recognize differences in thermal limits of species emerging from macrophysiological approaches that are due to biological mechanisms. We strongly advocate for the careful design, interpretation, and reporting of experimental results to ensure that conclusions arising from data synthesis efforts are grounded in theory.last_img read more

Oxford SU responds to the uncertainty over Trinity returns

first_imgThe sabbatical officers at Oxford SU have released an official response to the uncertainty over Trinity returns for students. This comes after a range of efforts from the student body, including petitions and letters to MPs, to reach greater clarity on the situation for students next term. In their statement, the sabbatical officers condemned the government’s handling of the situation: “This government has continued to ignore students and have failed to include Universities in the government roadmap. This is unacceptable. The government has broken their promises to provide more guidance on student return and has instead cancelled announcements leading to incredible amounts of stress and uncertainty for students that could have been avoided had university students not been repeatedly ignored.”They went on to highlight the guidance around current exemptions, and suggested that students should be the ones to make decisions on whether the exemptions apply to them. “We believe that students alone should be able to make their own decision about whether or not an exemption applies to them.”“We urge colleges to look favourably on requests to return made by students as we believe all students should be permitted to return to their accommodation if they feel they fall under the existing exemptions.” The SU also highlighted the “uneven implementation” of government policy across colleges.The SU has joined with the UUK, Student Minds, and NUS’ open letter, alongside contacting Michelle Donelan, the Minister for Universities. St Edmund’s Hall student, Sophie Richardson, has created a document collating the existing petitions, featuring templates for letters that can be sent to MPs, Michelle Donelan, and Kate Green, the Shadow Education Secretary.Image Credit: David Nicholls / CC BY-NC 2.0last_img read more

Speech: British High Commissioner comments on media shutdown and opposition ‘swearing in’ in Kenya

first_imgI have made clear, as have many international friends of Kenya for some time, that what we would like to see is a full, transparent, open dialogue between politicians and between others – business leaders, religious leaders, civil society – designed to heal some of the very deep divisions that were clearly exposed during the election campaign.I do not believe that any parallel inauguration helps to create such a dialogue, I think that the UK has been very clear that our support is for the constitution and for the law, and that those acting outside those things should not be doing so, but should be acting in the spirit of promoting dialogue.I will continue to call on both sides, and indeed on Kenyans of good will from all parts of the country, to find ways of talking to each other about how the institutions of the country can be strengthened and about how everybody can feel included in the future of the country. That is an exercise for Kenyans to lead, but I stand ready to support that as I know do my international friends.On the question of the media, I would just say that one of the strongest things about this country, one of the reasons that so many investors are headquartered here, that so many people come here, that this country’s capital is seen as the hub of the region and one of the hubs of the continent, is because of the open, democratic, free media; that sense that means people from country’s like mine feel at home, that sense that people can have open debates in public.I would urge the government, as I have done, to allow the media to operate freely, not simply because it’s the right thing to do, but because it contributes very strongly to the positive image that Kenya has in the world.Watch the British High Commissioner speak to the Kenyan presslast_img read more

Is Beyonce in Talks to Join The Wiz Live!?

first_imgCould Queen Bey reign as the Good Witch of the South? According to Us Weekly, pop goddess Beyoncé is in talks to play Glinda in The Wiz Live!. The NBC telecast will air on December 3.If she is in fact on board, she’d join fellow Grammy winners Mary J. Blige, Queen Latifah and Stephanie Mills, who are set to play Evillene, the Wiz and Aunt Em, respectively. The creative team is currently on the search for a newcomer to play Dorothy. We have a few suggestions.The ***flawless performer is certainly no stranger to bringing musical theater to the screen, having played Deena in the film adaptation of Dreamgirls and the title role in Carmen: A Hip Hopera.Kenny Leon will stage both the television production and subsequent Broadway revival of The Wiz in collaboration with Harvey Fierstein, who will contribute new material to the original book by William F. Brown. The show follows the familiar L. Frank Baum story of Dorothy and her adventures in Oz with a rock-filled revamp. Charlie Smalls’ score includes “Ease on Down the Road,” “No Bad News” and “Home.”This wouldn’t be Beyoncé’s first experience with The Wiz. Check out this clip of a seven-year-old Bey performing “Home” in her hometown of Houston! View Commentslast_img read more

Power Company Announces Unexpected Shutdown by Early 2018 of Two More Texas Coal-Fired Plants

first_imgPower Company Announces Unexpected Shutdown by Early 2018 of Two More Texas Coal-Fired Plants FacebookTwitterLinkedInEmailPrint分享Power Magazine:Vistra Energy moved to halt a financial hemorrhage stemming from unprofitable conditions in the Electric Reliability Council of Texas (ERCOT), announcing plans to shutter two more coal-fired power plants—the 1.1-GW Sandow Power Plant (which includes a 2009-built unit) and the 1.2-GW Big Brown plant—in early 2018.The company’s decision made public on October 13 comes on the heels of an announcement last week by Vistra Energy subsidiary Luminary to shutter its 1.9-GW coal-fired Monticello plant in Titus County.Vistra Energy said the coal plant closures are necessary because they are “economically challenged in the competitive ERCOT market.” Specifically, it said, “Sustained low wholesale power prices, an oversupplied renewable generation market, and low natural gas prices, along with other factors, have contributed to this decision.”“This announcement is a difficult one to make,” said Vistra Energy President and CEO Curt Morgan. “It is never easy to announce an action that has a significant impact on our people. Though the long-term economic viability of these plants has been in question for some time, our year-long analysis indicates this announcement is now necessary.”The Sandow plant in Bastrop County, central Texas, has two units, one built in 1981, and the other in 2009. The Big Brown plant in Freestone County also has two units that were brought online between 1971 and 1972.  Sandow and Big Brown are fired with lignite, though Big Brown supplements with Powder River Basin coal.In September 2009, Luminant completed the 581-MW Sandow 5 unit in Milam County, Texas—the first new coal unit build in Texas in 17 years. It uses circulating fluidized bed technology and burns Texas lignite coal.
