Antarctica is an isolated continent whose conditions challenge the survival of living organisms. High levels of endemism are now known in many Antarctic organisms, including algae, tardigrades, nematodes and microarthropods. Bdelloid rotifers are a key, widespread and abundant group of Antarctic microscopic invertebrates. However, their diversity, regional distribution and endemism have received little attention until recently. We provide the first authoritative review on Antarctic Bdelloidea, based on published data and new collections. Our analysis reveals the extreme levels of bdelloid endemism in Antarctica. Sixty-six bdelloid morphospecies are now confirmed from the continent, and 83–91 putative species are identified using molecular approaches (depending on the delimitation method used). Twelve previously unknown species are described based on both morphology and molecular analyses. Molecular analyses indicate that only two putative species found in Antarctica proved to be truly cosmopolitan. The level of endemism based on the available data set (95%) is higher than that in any other continent, with many bdelloid species occurring only in maritime or continental Antarctica. These findings are consistent with the long-term presence of Bdelloidea in Antarctica, with their considerable isolation facilitating intraregional radiation, providing further evidence that does not support the microbial global ubiquity hypothesis that “everything is everywhere.”

FacebookTwitterLinkedInEmailPrint分享Molly Christian for SNL:The Obama administration wants to double federal investment in clean energy research and development over the next five years to follow through on an international commitment reached with world leaders at the Paris climate summit in December 2015.President Barack Obama released a plan Feb. 6 to boost federal investment in clean energy R&D to $12.8 billion in fiscal year 2021 from $6.4 billion in fiscal year 2016. The proposal is geared toward helping the U.S. meet its commitment to Mission Innovation, an initiative launched by global leaders during the Paris talks to accelerate public and private investment in clean energy innovation.“This investment portfolio spans the full range of research and development activities — from use-inspired basic research to demonstration,” the White House said in the Feb. 6 release.In fiscal year 2017, Obama is seeking $7.7 billion in discretionary funding for clean energy R&D, an approximately 20% increase from the year before. The funding will be spread out across 12 federal agencies.About 80% of the government’s Mission Innovation investment will support the U.S. Department of Energy’s research, development and demonstration activities. One of the largest single DOE funding tranches for fiscal 2017 is more than $1.8 billion for basic research on clean energy production, conversion, storage and use.Sustainable transportation technologies will also get a large chunk — over $880 million — of DOE innovation funding. After focusing on electric power sector carbon emissions in 2015 with the release of its final Clean Power Plan, the Obama administration has turned its attention more to the transportation sector’s role in climate change. The administration on Feb. 4 proposed a controversial $10 per barrel tax on oil that would help fund the transition to a cleaner transportation system.Despite the recent emphasis on transportation, the utility sector factors heavily in the clean energy R&D investment outlook. Research and development of advanced nuclear technologies will receive more than $804 million in fiscal 2017 under Obama’s budget proposal. Nearly $564 million is targeted for developing and deploying carbon capture and storage technologies and improving the emissions performance of fossil fuel-based generation. DOE investment in boosting dispatch and lowering costs for renewable generation will receive over $500 million.Full article ($): bama unveils plan to double clean energy R&D in next 5 years Obama Administration Doubles Clean Energy R&D to $12.8 Billion
Twenty-two-year-old Michael Emmanuel was on Monday arraigned for the murder of Leonard Peters when he appeared at the Georgetown Magistrates’ Courts.He was not required to plead to the indictable charge which stated that on December 21 at Lot 7 West Watooka, Linden, he murdered Peters, also called Lenny.The accused was unrepresented at the time of his appearance.
