Laboratory studies of assimilation and egestion of algal lipid by Antarctic krill — methods and initial results

first_imgImmature Antarctic krill (Euphausia superba Dana) (length 44–48 mm), which had been maintained in an aquarium, were fed dense suspensions of algal culture, either the haptophyte Isochrysis or the diatom Thalassiosira. Following acclimation to this regime, the animals were transferred to identical supplies of the same algal food, pre-labelled with 14C bicarbonate for 16 h. Faecal pellets were collected individually in each experiment. Following transfer to the radiolabelled food, radioactivity appeared in faecal pellets after 30 min for Isochrysis and 55 min for Thalassiosira. Fitting a first-order kinetic model to the time-course of appearance of radiolabel in faecal pellets, showed that gut turnover (mean residence time of material in the gut) was rapid for krill fed on Isochrysis (turnover time = 47 min) whilst krill took longer to process Thalassiosira (turnover time = 256 min). Uptake rate of radiolabel by the two algae differed by an order of magnitude and was inversely related to cell size. Removal of the two algal species by the krill also differed when expressed as either chanages in radiolabel or biomass but overall, similar amounts of lipid were ingested from the two food sources (817 and 615 ng· ml−1 over 12 h for Isochrysis and Thalassiosira, respectively). Assimilation efficiencies for the two algae, calculated on the basis of radiolabelled and total-lipid ingestion and egestion ranged from 63 to 86%. Most of the radioactivity in the fatty acids of Isochrysis was incorporated into C18 compounds, but this distribution did not correspond to the overall mass composition of algal fatty acids. Saturates, 16:1, 18:4 and 20:5 were labelled to a lesser extent. Radiolabelled fatty acids incorporated into krill gut and somatic tissue differed in composition from the original algal fatty acid pool. In particular, there was higher activity in saturates, in 16:3 and 18:4, whilst 18:1, 18:2 and 18:3 were labelled to a lower extent in krill. Overall, fatty acids showed lower specific activity in krill than in algae, except for 16:3. The distribution of radioactivity in faecal pellets showed a character more strongly related to that of the algal food supply than that of the krill, although the high proportion of label in saturates (predominantly 16:0) was derived from the animals. Much of the ingested fatty acids were subsequently catabolised. Taking all the fatty acids, 69% appeared to be lost by this route, indicating the major importance of fatty acids as an energy source for krill. However, some individual fatty acids were conserved, for example saturates and 18:4. In the latter case, biosynthesis from 18:3 is implied. Overall, the study indicates the importance of constructing detailed budgets in understanding the character and dynamics of feeding by Zooplankton and suggests that control of grazing by quality as well as quantity of the food supply may be a crucial aspect of understanding ocean carbon cycling.last_img

Groups say Hoosiers with disabilities still face ballot barriers

first_img Groups say Hoosiers with disabilities still face ballot barriers Twitter Google+ Facebook Pinterest Facebook WhatsApp IndianaLocalNews (Photo supplied/Adobe stock) (Indiana News Service) The pandemic has pushed the issue of voter access to the forefront, but for Indiana’s disability community, it’s more than just another talking point.Voter turnout for people with disabilities was 6 percentage points lower than that of people without disabilities in the 2016 presidential election. Jessica Trimble, director of communication and outreach at Indiana Disability Rights, said typically the reason people with disabilities might forego casting a ballot is because of troubles they’ve encountered when voting in the past.“So if they’ve had a negative past experience for any reason – be it transportation, be it the polling location, be it poll workers – the chance of them going to vote again drops significantly,” Trimble said. “So that is a really big challenge that is really impacting a large community.”It’s estimated nearly 60% of polling locations in the country are inaccessible in some way, shape or form.This year all Indiana voters can cast a ballot early in person starting today. Absentee voting by mail is reserved for people who cannot physically be present to vote on Election Day and requires a documented excuse.A recent study from Rutgers University found roughly 874,000 eligible voters in Indiana have a disability, which represents nearly 18% of the total electorate for the general election.Director of the Disability Justice Initiative at the Center for American Progress Rebecca Cokley contends election officials and candidates need to ensure everyone can cast a ballot.“The disability vote matters,” Cokley said. “The disability community saved the Affordable Care Act back in 2017. We are a strong community; we are a politically active community. And so it actually behooves them to make voting as easy as possible for people with disabilities.”Trimble advises Hoosiers with disabilities to vote in the manner they feel most comfortable, and if possible, to vote early and in person. She noted those who feel they need additional assistance can contact their local county clerk’s office to request a travel board.“The travel board is made up of a volunteer of each of the major political parties, and they actually bring a ballot to your house,” Trimble said. “They can support you in completing the ballot if you need help, and then they make sure it’s sealed, it’s signed and it gets delivered to the clerk for you.”Voting information for individuals with disabilities is available at indianavoters.com.Support for this reporting was provided by The Carnegie Corporation of New York.

“New Realities” and Russian markets

first_img Read Full Story During the April 10 discussion at Harvard’s Davis Center for Russian and Eurasian Studies the representatives of academia and business presented the Moscow-based International Center For Emerging Markets Research. The long-term goal of the center is to foster dialogue of academia and business both locally and globally.A new bottom-up research initiative by Russian and foreign experts — the International Center For Emerging Markets Research (ICEMR) at The Peoples’ Friendship University of Russia (RUDN University) — seeks to establish closer cooperation with Harvard University as well as foster understanding of economic realities in Russia and other emerging markets. However, in the long-run, it pursues a more audacious goal — bridging the gap between big business and academia in Russia and other countries with transition economies.It was presented on April 10 at Harvard’s Davis Center for Russian and Eurasian Studies during the “New Reality and Russian Markets” discussion and brought together both Russian and foreign researchers. The initiators of the Center make it clear that they have a very bold plan to become one of the leading academic hubs to provide hard analysis on emerging markets, focusing on Russia and its relations with the U.S. and Europe. The final goal is to attract big business and found common ground with those who are used to earning money and cutting deals.According to Andrey Berezin, director for development at ICEMR, business and academia have  to work together to drive innovations.—By Pavel Koshkinlast_img

Alumna explores loss, consolation in poetry

first_imgListeners witnessed the journey from brokenness to consolation at a poetry reading in Carroll Auditorium Tuesday night at Saint Mary’s College. Mary Pinard, a Saint Mary’s alumna and professor of English at Babson College, read from her book “Portal” as part of the spring season’s visiting writer series, sponsored by the English department.Pinard said her brother drowned during a freak tugboat accident in the Grays Harbor Estuary in Washington, and the event inspired the content of the collection.“‘Portal’ is a book which started with a personal story, a story of deep loss for me, that I think blinded me from being anything but sad for a long time,” Pinard said. “I worked my way through some very raw places, trying to find a voice, an elegiac voice that could somehow respond to the loss of a beloved brother.”The resulting book is her personal elegiac journey from brokenness to consolation, she said. The book begins with a poem full of broken descriptions, titled “Theory of Disappearance,” followed by a series of poems involving the speaker talking to the lost brother.Writing a sonnet about her brother’s love of the smell of diesel, a poem about film found in the pocket of his raincoat after his death and another titled “Blue Lath” — named after a woodworker’s tool used by her brother —among other poems, helped her move forward towards consolation, Pinard said.“Late in the series [of poems] is where I am trying to face the matter of my brother’s death, and to make sense of it,” Pinard said.Pinard said the image of peonies inspired a poem titled “Seeing Peonies,” written during a writing residency in Peoria, where she went to learn more about tugboats, so as to better understand the environment in which her brother died.The book ends with a poem of praise for an estuary, she said.“The complexity that is in an estuary, where saltwater and freshwater braid, suggests that there are species that can only survive there,” Pinard said. “Because it is so easy to discount it, it is also so easy to hurt it. For me, the coming together of consolation and the loss of my brother connects with my sense of consolation around trying to understand the nature of the estuary and potentially to save it.”In response to a student question, Pinard said she developed a love of the languages of sciences after switching her course of study from pre-med to theater and English her sophomore year at Saint Mary’s.“I do think that there is a lot of beauty in language that poets can have access to, if they have a better relationship with disciplines that seem different from theirs,” Pinard said. “I think that’s the beauty of poetry. If you take it seriously, then you have to become a scholar in a lot of different areas, if you are going to make all of those language work in those poems.”First-year student Emily Harrast said she enjoyed the reading because she finds herself similar to Pinard because she is a biology major who also likes English. “It was interesting how she talked about poetry in relation to other subjects,” Harrast said. “I also thought it was interesting how she made the whole book about [the loss of her brother]. You could really tell how she changed over time, how she started the book so upset and then grew from there, eventually viewing something completely different from the same situation.”Tags: Mary Pinard, Poetry, Saint Mary’s College, visiting writer serieslast_img

Equinor sees potential for 20GW of offshore wind capacity in England’s Dogger Bank area

first_img FacebookTwitterLinkedInEmailPrint分享Recharge:The renewables chief at Norwegian oil & gas group Equinor said the world’s biggest offshore wind farm it’s building off eastern England could be just the start of a renewable mega-hub with potential for more than 20GW of power production in the North Sea – enough to supply one third of UK electricity demand.Scoping work by Equinor, which is co-developing the first 3.6GW at Dogger Bank in partnership with UK utility SSE after winning a British government power deal last year, suggests “the total potential in the broader Dogger Bank area can be multiplied by a factor of six,” said Pål Eitrheim, executive vice president for New Energy Solutions at Equinor. “We see Dogger Bank as a strategic power hub.”The Equinor/SSE Dogger Bank development, along with another underway in the area by Innogy, are already set to make Dogger Bank a massive source of renewable power for the UK from the mid-2020s, but Eitrheim indicated the Norwegian group’s interest in the area won’t stop there.“When our people look at the total wind resources, there is much more potential in that area than the 3.6GW that we are going to develop today in terms of technical wind resources,” Eitrheim told Recharge on the sidelines of Equinor’s annual capital markets update to investors in London.Eitrheim referenced Dogger Bank’s wider potential as he set out how major offshore wind clusters will be a central part of Equinor’s strategy as it pursues its ambition to be an “offshore wind major” with up to 16GW of renewables installed by 2035. Equinor, which is majority-owned by the Norwegian government, is also active in US offshore wind, where its Empire State project has already won a tender in New York.Beyond its fixed-bottom offshore wind plans, Eitrheim said Equinor sees floating wind power, where the group is a technological pioneer through its Hywind Scotland, and Hywind Tampen arrays, as a “gateway to Asia.”[Andrew Lee]More: Equinor sees 20GW bigger picture at world’s largest offshore wind farm Equinor sees potential for 20GW of offshore wind capacity in England’s Dogger Bank arealast_img
