Widespread amplification of amplified fragment lengthpolymorphisms (AFLPs) in marine Antarctic animals

first_imgAlthough recent years have witnessed a rapidgrowth in the number of genetic studies of Antarctic organisms,relatively few studies have so far used nuclear markers,possibly due to the perceived cost and diYculty ofisolating markers such as microsatellites. However, anoften overlooked alternative is to use ampliWed fragmentlength polymorphisms (AFLPs), a versatile and low-costmethod capable of generating large numbers of predominantlynuclear loci in virtually any organism. We conducteda literature review of population genetic studies of Antarcticorganisms, Wnding that fewer than 10% used AFLPs.Moreover, a strong taxonomic bias was found, with studiesemploying mitochondrial DNA or microsatellites focussingpredominantly on animals, while those using AFLPs weremostly of plants or lower organisms. Consequently, weexplored the extent to which AFLPs amplify across a rangeof Antarctic marine animal taxa by genotyping eight individualseach of twelve diVerent species, ranging from echinodermsthrough soft corals to pelagic Wsh, at four selectiveprimer combinations. AFLPs readily ampliWed across all ofthe taxa, generating between 32 and 84 loci per species,with on average 56.5% of these being polymorphic. In general, levels of polymorphism bore little relationship with expectations based on larger populations of broadcastspawning species being more variable, though we did find a tentative positive correlation between the number of AFLP bands ampliWed and a measure of eVective population size. Our study lends further support for the utility and ease of use of AFLPs and their suitability for studies of Antarctic species across a wide range of taxa.last_img read more

BAE gets $26M for USS Harpers Ferry maintenance work

first_img BAE Systems gets $26M for USS Harpers Ferry maintenance work Authorities View post tag: US Navy February 6, 2017 Back to overview,Home naval-today BAE Systems gets $26M for USS Harpers Ferry maintenance work The U.S. Navy has awarded BAE Systems San Diego Ship Repair a $26.6 million contract modification for work on the phased maintenance availability of USS Harpers Ferry (LSD-49).The lead ship in her class of dock landing ships will undergo depot-level maintenance, alterations, and modifications during the maintenance.Work on the USS Harpers Ferry will be performed in San Diego, California, and is expected to be completed by January 2018.Sister ship USS Oak Hill (LSD-51) will complete the same maintenance period by April 2017 with the only exception being that the work will be performed by General Dynamics in Norfolk.All ships in the Harpers Ferry-class underwent a midlife upgrade between 2009 and 2014 and are now expected to remain in service through 2038.

Ministry provides Rp 7.2 trillion in phone credit, data packages to support distance learning

first_imgThe Education and Culture Ministry will provide Rp 7.2 trillion (US$532 million) in social assistance in the form of phone credit and internet data packages to support students and teachers conducting long-distance learning for the next four months.Minister Nadiem Makarim announced the plan during a meeting with the House of Representatives Commission X overseeing education on Thursday.“We hope these subsidies can help all students and teachers [during this pandemic],” said Nadiem. The subsidy will be disbursed to school students in form of a 35 gigabytes (GB) internet data package every month, while teachers will receive a 42 GB data package.University students and lecturers will receive a 50 GB data package per month for the next four months.Read also: Local communities provide free internet, gadgets to students amid e-learning barriersNadiem said the cost of data and phone bills had been a major concern among parents, as students have been forced to learn remotely during the school closures amid the outbreak.The secretary of the ministry’s Early childhood, Elementary and Secondary Education Directorate General, Sutanto, said the phone credit and internet data packages would be transferred directly to the students and teachers’ phone numbers that were registered with local education agencies.The ministry has also secured an additional Rp 1.7 trillion in assistance funds to be given to teachers, lecturers and other education sector workers. The money was taken from the reallocation of funds from several programs, including the Mobilization Organization Program (POP) that will be suspended until 2021.Topics :last_img read more

Governor Wolf Statement on Budget and Education Funding

It is long past time for the legislature to move ahead with this agreement and end this impasse.“This agreement, that Republican leaders stood outside my office twice to announce, includes an additional $60 million for early childhood education, which will create 14,000 new slots for children, it invests $400 million new dollars into K through 12 education, a hugely important first step in restoring the cuts made to school funding, and the agreement increases higher education funding by 5 percent.“I urge the legislature to come together and pass the budget with this historic education funding and begin to move the commonwealth forward.”last_img read more
