Long-term studies at Bird Island, South Georgia, show that numbers of wandering, black-browed and grey-headed albatrosses have been decreasing since the late 1970s. To determine the status of the total South Georgia population, all known colonies were censused in 2003/2004 using a combination of yacht-based digital photography and ground counts. The breeding population estimates from this census are 1,553 pairs of wandering albatross, 74,296 pairs of black-browed albatross and 47,674 pairs of grey-headed albatross. A 30% decline since 1984 was recorded for wandering albatross, and comparison of a sample of black-browed and grey-headed albatross colonies on the mainland of South Georgia photo-censused in both 1985/1986 and 2003/2004 indicates similarly substantial population declines. Unless these decreases can be halted or reversed, doubt will exist as to the long-term viability of these species of albatross at South Georgia.
It is argued that Larsen Ice Shelf contains marine ice formed by oceanic freezing and other mechanisms. Missing basal returns in airborne radar soundings and observations of a smooth and healed surface coincide downstream of regions where an ocean model predicts freezing. Visible imagery suggests that marine ice currently stabilizes Larsen C Ice Shelf and implicates failure of marine flow bands in the 2002 Larsen B Ice Shelf collapse. Ocean modeling indicates that any regime change towards the incursion of warmer Modified Weddell Deep Water into the Larsen C cavity could curtail basal freezing and its stabilizing influence.
The efficiency of deep-ocean CO2 sequestration is regulated by the relative balance between inorganic and organic carbon export respectively acting through the biological carbon pump (BCP) and the carbonate counter pump (CCP). The composition and abundance of calcifying species in the prevailing oceanic plankton community plays a major role in driving the CCP. Here we assess the role of these calcifying organisms in regulating the strength of the CCP in a Southern Ocean region (northern Scotia Sea) known to be a major hotspot for the drawdown of atmospheric CO2. We show that, when shelled pteropods dominate the calcifying community, the total annual reduction of CO2 transferred to the deep ocean doubles (17%) compared to when other plankton calcifiers dominate (3–9%). Furthermore, predation enhances their contribution through the removal of organic soft tissue. Pteropods are threatened in polar regions by ocean warming and acidification. We determine that their potential decline would have major implications to the comparative strengths of the BCP and CCP.
We review the evidence for predation of shelly benthic prey over 125 million years of earth history in the James Ross Basin, Antarctica (~65°S). Although poor in the Early Cretaceous lower parts of the sequence, which represent essentially deeper water facies, evidence for both potential crushers and drillers becomes more apparent in the Santonian – Campanian Santa Marta Formation, and by the Maastrichtian López de Bertodano Formation there is an extensive fossil record of drill holes attributable to naticid gastropods, and some evidence of crushing by decapods crustaceans and possibly other taxa too. This continues at a similar level of intensity across the K/Pg boundary into the Danian Sobral Formation, but is less well constrained in the latest Paleocene – Early Eocene. The most extensive record of predation occurs in the Middle Eocene section of the La Meseta Formation on Seymour Island which also records the highest levels of benthic diversity within the entire basin. This key section is providing some important new evidence to suggest that the rate of acceleration of benthic predation intensity through the Late Mesozoic – Early Cenozoic in the polar regions may be similar to that seen in lower latitude regions. Predator – prey interaction was a key factor in the evolution of polar marine faunas too.

Beau Lund FacebookTwitterLinkedInEmailUniversity of Notre Dame(NOTRE DAME, Ind.) — Lynette Wukie, a junior at the University of Notre Dame, is making history one cheer at a time.The Ohio native made her debut on Monday as the first female leprechaun in the Catholic university’s 177-year history. “I’m happy to be in this position to show girls or anyone of any race or gender that you can do anything,” Wukie, 21, told ABC News’ Good Morning America. “I’m very excited.”In addition to being the first woman to hold the prestigious mascot role, Wukie is one of only three African Americans in school history to hold the role.She is in a three-person leprechaun class this year that includes another African American student, Samuel Jackson, and Conal Fagan, the first native-born Irishman to be mascot.“I know all three of us are just really excited,” Wukie said. “It’s an interesting dynamic because we have kids look up to us and now we show a different representation.”Wukie, a high school cheerleader, came to Notre Dame after breaking the glass ceiling in another sport: golf. She worked as the only female golf caddie in her hometown near Cleveland, while in high school.Through caddying, she was granted the Chick Evans Scholarship, a four-year tuition and housing college scholarship offered to students who have made a job of toting golf clubs.Once at Notre Dame, Wukie became a film, television and theater major and never thought she could become the school’s mascot until she was encouraged by a previous mascot to try out.“I was very skeptical about whether I should,” Wukie said. “A lot of my fear just came from regular old stage fright and I think being a woman was a little off-putting too because there hadn’t been a woman predecessor.”“I thought if I do all of this and don’t get it I’m going to be embarrassed because it’s a very public thing,” she added. “But I realized that if I wanted to do it, then all of that was worth it.”Wukie submitted her application and was chosen as a top-5 finalist.Her finals tryout consisted of performing in front of a mock pep rally, where she had to adapt, because all the uniforms were in men’s sizes. She was also interviewed by judges, where she said the topic of being a woman was discussed.“One of the [judges] said it never crossed her mind that a leprechaun could be female and she apologized because she said it should have,” Wukie recalled. “I told her not to apologize because I didn’t think of it either.”“It was one of those things where that’s how it’s always been and that’s how we always thought it would be, but here we are,” she said.Wukie found out last April that she was one of the three students chosen to be a leprechaun. She spent the summer preparing for the role, including figuring out how to make it her own.“We have done our best to keep the tradition but adapt it to me being female,” she said. “I still have a suit, but the pants are cuffed instead of cinched and both the coat and the vest are shorter so it’s more of how a women’s suit would look.”“I wear an ascot type scarf, but I can also wear the tie if I want, it’s my choice,” Wukie added.The Notre Dame leprechaun is one of the few collegiate mascots whose costume does not include a head piece. For many years, the leprechaun role came with gender and height requirements and required the ability to grow a beard, according to Delayna Herndon, a University of Notre Dame cheerleading coach.“So far the reaction to having a female portray the leprechaun has been overwhelmingly positive,” Herndon told GMA. “[Wukie] truly is a role model for so many young men and women wanting to strive for whatever they’re passionate about.”Wukie and her fellow mascots are considered student-athletes and train with the school’s cheerleading team. One mascot is chosen to cheer at Notre Dame football games, while all three, including Wukie, cheer on the school’s other sports teams, from soccer to volleyball and basketball.Wukie said her fellow students recognize her on campus and she has already experienced young girls running up to meet her and give her high fives. The reaction is a far cry from the controversy she feared as a barrier-breaker.“I think it’s something that’s natural with anything like this, when there’s a first, especially with gender, that something will come up,” she said. “Also being a woman of color, I feared there would be a lot of controversy, but I’ve heard only positive things both here and back home.”“I hope that having a female leprechaun continues as a tradition,” Wukie added. “I hope I won’t be the only one.”Copyright © 2019, ABC Radio.
