Nematode diversity and distribution in the southern maritime Antarctic – clues to history?

first_imgNematode worms are one of the most important soil faunal groups in Antarctica. However, relatively little is known about their widerdistribution, biogeography and history in the region, and taxonomic information remains confused or incomplete. Here, we hypothesisethat the Alexander Island (southern maritime Antarctic) fauna includes elements that have survived (at least) the period of Pleistoceneglaciation in situ, forming a regional centre of endemism and biodiversity hotspot. We describe nematological surveys carried out acrossa latitudinal gradient between 68 and 771S along the southern Antarctic Peninsula, comparing the data obtained with the maritimeAntarctic fauna described in the few previous studies between northern Marguerite Bay and the South Orkney Islands (60–681S). Ingeneral, our survey supports previous findings of a lack of overlap at species level between the maritime and continental Antarcticbiogeographical zones, with the large majority of specimens obtained from all survey sites being attributable to known maritime or newand currently endemic taxa. However, collections from Alexander Island, Alamode Island and the most westerly site sampled, CharcotIsland, include specimens morphologically very close to two known continental Antarctic species, which may indicate a link between thetwo regions. The fauna obtained at the northern study sites (ca. 681S, Adelaide Island, Marguerite Bay) closely matches that describedpreviously. However, in contrast with widely described patterns of decreasing diversity in other Antarctic biota, species richnessincreased markedly at locations on Alexander Island (ca. 721S), including a substantial element of undescribed species (50% of taxaacross all locations, 40% of taxa found on Alexander Island). Finally, the most southerly samples obtained, from inland nunataks inEllsworth Land (75–771S), indicate a fauna that does not include nematodes, which is exceptional not only in an Antarctic context butalso for soils worldwide.last_img read more

Multi-Ship refueling keeps Operation Atalanta warships on patrol

first_img Training & Education Back to overview,Home naval-today Multi-Ship refueling keeps Operation Atalanta warships on patrol July 27, 2016 Multi-Ship refueling keeps Operation Atalanta warships on patrol Operation Atalanta’s warships are deployed off the coast of Somalia to ensure that the pirate attacks that terrorized seafarers in the Indian Ocean and Gulf of Aden for a number of years are not allowed to resurge.In order to ensure that the EU NAVFOR warships are able to maintain their counter-piracy patrols for longer periods, the ships top up their fuel and other essential stores, such as food, by conducting a Replenishment at Sea (RAS).Operation Atalanta’s German tanker, FGS Spessart, recently rendezvoused at sea with flagship, FGS Bayern, and Italian warship, ITS Euro, to conduct a RAS.Refueling one ship is a complicated manoeuvre that requires focused communication and high levels of skill from all the crews involved. When another ship is added to the mix, the manoeuvre becomes even more complex and safety concerns increase.After the RAS procedure was safely and successfully completed, the EU Naval Force’s ships returned to their duties to deter and disrupt the piracy threat off the Somali coast.During a recent multi-ship RAS, all four Operation Atalanta ships sailed togethercenter_img View post tag: EU NAVFOR View post tag: Operation Atalanta Share this articlelast_img read more

Phil Lesh Plays Surprise Show With The Majority Of Circles Around The Sun

first_imgAfter wrapping up two great shows at Terrapin Crossroads with “Darkness” and “Light” themes, bassist Phil Lesh surprised fans at his venue with a performance last night. Lesh called on some players that had been present for the last two nights, who incidentally comprise three-fourths of the famed instrumental group Circles Around The Sun: guitarist Neal Casal, keyboardist Adam MacDougall and drummer Mark Levy.Circles Around The Sun was a project borne out of “Fare Thee Well,” the Grateful Dead’s 50th anniversary show. The band was asked to compose instrumental music for the setbreaks, and wound up creating one of the most prized album releases of 2015 in the process. You can read our conversation with Casal about it here.Though the band didn’t play any Circles pieces, they did start each set out with instrumental jams that were reminiscent of them. The free show featured some Grateful classics like “It Must Have Been The Roses” and “Friend of the Devil.” You can watch some video highlights, courtesy of Troy Hooper, below.Peggy-ONo ExpectationsCheck out the full setlist below, courtesy of Jambands.Setlist: Phil Lesh & Friends at Terrapin Crossroads, San Rafael, CA – 7/7/16Set I: Jam > Peggy-O, She Belongs To Me, It Must Have Been The Roses, No Expectations, Friend of the DevilSet II: Jam > Mountains of the Moon, After Midnight, Mission In The Rainlast_img read more

Board liaisons direct directors and staff toward good governance

first_imgCredit union leaders have become increasingly aware of the importance of good governance and have made an effort to ensure that their credit unions are adopting cutting-edge governance and leadership practices. From assessing the effectiveness of their boards and governance systems to updating their governance frameworks, policies and procedures to improving their board structures, committees and charters, good governance is taking center stage.These efforts—along with the steady workload of supporting a credit union board—require strong leadership from the board chair, CEO and a governance committee, but also from an often-overlooked and under-appreciated staff person—the board liaison. At a minimum, today’s board liaisons help to organize and disseminate meeting materials, plan and support the execution of board meetings and retreats, take minutes, and generally help keep things organized and on track so that the board can do its work.But more and more, the board liaison’s role is being expanded and now is considered by many a management position that has been tasked to actively support—and improve—the board’s work. In its expanded role, board liaisons also ask a fundamental question regarding good governance: How can the credit union’s board and governance become even more effective? continue reading » ShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more

GSG introduces diversity resolution

first_imgThe Graduate Student Government introduced a resolution at its meeting Monday night, calling on the University to adopt policies that would “effectively measure and improve the diversity, equity and inclusion climate on USC’s campus relevant to ethnicity, gender and sexuality.”Typically, GSG votes on resolutions one month after they are introduced, but the senate voted unanimously with one abstention to hold an expedited online vote on the resolution next week.“Students have been organizing and have been active on these issues for years, and yet our administration has failed to provide a comprehensive and strategic plan,” GSG Vice President Christina Gutierrez said at the meeting. “Administrators have instead promoted a reactive tool aimed at reporting incidents of bias rather than working to prevent them.”Undergraduate Student Government President Rini Sampath, one of the principal authors of the collaborative resolution between USG and GSG, echoed this frustration.“Students have been doing this work for years and years now and we’ve gotten no real response from the administration, no real plan of action to tackle these issues other than the bias discrimination report system and the Together USC campaign [to be] launched by Student Affairs,” Sampath said. “I think we need to take a look at the systems we have in place and the policies we have in place that foster this kind of intolerant environment.” In her remarks, Gutierrez cited an incident on Sept. 19 involving Sampath in which a fraternity member yelled “You Indian piece of s*it!” and threw a drink at her, calling it  “xenophobic hate speech on campus.”“Unfortunately, what happened to Rini isn’t an isolated incident — it is evidence of a larger problem at USC,” she said at the meeting.Gutierrez further noted the ongoing Title IX investigation at USC, student reports of bias on the “I, Too, Am USC” Facebook page, the recent campus climate survey in which nearly 30 percent of female undergraduates who responded said they had experienced sexual assault and a forum held by USG on Sept. 30 that discussed the issue of diversity as examples of the larger problems with the campus climate. “With the incident that happened to Rini, and her publishing it and it getting national media attention, I think USG and GSG and leaders from student organizations recognized that we have a unique opportunity with this national media attention to continue to further urge our administration to act and this is the first time that USG and GSG have collaborated on this kind of campaign and initiative,” Gutierrez said in an interview with the Daily Trojan.Gutierrez said that the current mechanisms in place, namely an online form for reporting incidents of bias, are insufficient and that the administration has not followed through with its promises to increase student awareness, distribute educational resources and collaborate with students and cultural assemblies. “What the administration has presented to our student body have been reactive measures to report incidents after they happen but nothing really focused on how we address the culture that allows these incidents to persist,” Gutierrez said. “We’re looking at how we address that culture and [how to implement] preventative measures.”The resolution calls on the administration to hire a vice president of diversity, equity and inclusion to develop a strategic plan to improve campus climate. The vice president would then work with the academic deans of each academic division or school within the University to hire a vice dean for diversity, equity and inclusion. The resolution asks for undergraduate and graduate students to be involved in all of the hiring processes. “We’re really calling on our administration to put together a comprehensive and strategic plan to address these issues rather than pointing us to a kind of piece-meal, after-the-fact kind of resource,” Gutierrez said.The resolution further asks the administration to increase access to demographic metrics for students, faculty and staff, and increase transparency and accountability for reports of bias incidents and Title IX complaints. In addition, the resolution requests the University develop a plan for addressing diversity, equity and inclusion within a year as well as to significantly increase the number of underrepresented students, faculty, staff and trustees to reflect national demographic levels by 2025. The resolution calls for the creation of a $100 million fund to support underrepresented undergraduate and graduate students and tenured faculty positions for underrepresented minorities. Finally, the resolution calls for the University to redefine and recommit itself to diversity, invest additional resources in cultural centers, and create a space for dialogue about campus issues. It also seeks mandatory diversity and cultural competency training for graduate students, student leaders and faculty. Sampath feels the list of demands is necessary to elicit action from the University. “We have tried asking for some things, and those requests haven’t been met in the past so the mentality we have right now is dream big,” Sampath said. “We know that we can’t resolve issues of discrimination overnight, but we need to set the standard.”Sampath pointed out that UCLA, a public university, has a vice chancellor for equity and diversity.“It’s something so reasonable to ask that our university invest its resources and reprioritize its resources when it comes to issues of how students are feeling on this campus as a whole,” she said.Gutierrez said resources are already in place, citing the example of the Center for Urban Education within the Rossier School of Education, which has developed an equity scorecard tool for equity analysis and has implemented this tool at universities around the country, but not at USC.“We have the resources, we have the support in place, it’s just a matter of the administration really valuing and taking this seriously and utilizing those resources to address the problem.”The resolution is supported by several organizations including the Black Graduate Student Network, Awujo House, the Student Coalition Against Labor Exploitation, the Asian Pacific Graduate Student Association and the Black Alumni Association. The resolution will be presented at the weekly USG Senate meeting Tuesday night.“[The resolution] is what students have been asking for years now, but it’s something that we’re now as a student collective writing down and putting it on one document where we can say, “This is what we need to see in terms of change happening at our University,” Sampath said.last_img read more

Jones Alhassan Abu opposes cancellation of current Division One campaign

first_imgExecutive Director of Tamale City FC Jones Alhassan Abu has kicked strongly against the possibility of cancelling and restarting the Division One League season.With no return date in sight for football in the wake of the Covid – 19 pandemic, discussions on nullifying the current league campaign have been ongoing with teams divided on the matter.The veteran administrator believes the idea of truncating another campaign should not be entertained because it renders the league brand unattractive to potential corporate sponsors.“Out of the 16 clubs in the zone we are currently third despite all the challenges we have been facing.“We have lost our financiers and have had to start from scratch but even with that you can tell the potential this team has.“If you were to truncate this league again and we have to find money to start again what signal are you sending to corporate bodies who put in money to buy broadcast rights only for the league to go halfway and then see it cancelled.“How are they going to get value for their money?“They are not father Christmas’ but  commercial entities.“For all these reasons the null and void brigade should not be countenanced at all,” he stated in an interview with Citi Sports.The Ghana Football Association is currently playing the waiting game with the hope of making a decision on the matter by the June 30, 2020.last_img read more
