    Response to comment on "The placental mammal ancestor and the post-K-Pg radiation of placentals" (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-08-10
    Description: Tree-building with diverse data maximizes explanatory power. Application of molecular clock models to ancient speciation events risks a bias against detection of fast radiations subsequent to the Cretaceous-Paleogene (K-Pg) event. Contrary to Springer et al., post-K-Pg placental diversification does not require "virus-like" substitution rates. Even constraining clade ages to their model, the explosive model best explains placental evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Leary, Maureen A -- Bloch, Jonathan I -- Flynn, John J -- Gaudin, Timothy J -- Giallombardo, Andres -- Giannini, Norberto P -- Goldberg, Suzann L -- Kraatz, Brian P -- Luo, Zhe-Xi -- Meng, Jin -- Ni, Xijun -- Novacek, Michael J -- Perini, Fernando A -- Randall, Zachary -- Rougier, Guillermo W -- Sargis, Eric J -- Silcox, Mary T -- Simmons, Nancy B -- Spaulding, Michelle -- Velazco, Paul M -- Weksler, Marcelo -- Wible, John R -- Cirranello, Andrea L -- New York, N.Y. -- Science. 2013 Aug 9;341(6146):613. doi: 10.1126/science.1238162.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomical Sciences, HSC T-8 (040), Stony Brook University, Stony Brook, NY 11794-8081, USA. maureen.oleary@stonybrook.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23929968" target="_blank"〉PubMed〈/a〉

    The placental mammal ancestor and the post-K-Pg radiation of placentals (2013)

    Publication Date: 2013-02-09
    Description: To discover interordinal relationships of living and fossil placental mammals and the time of origin of placentals relative to the Cretaceous-Paleogene (K-Pg) boundary, we scored 4541 phenomic characters de novo for 86 fossil and living species. Combining these data with molecular sequences, we obtained a phylogenetic tree that, when calibrated with fossils, shows that crown clade Placentalia and placental orders originated after the K-Pg boundary. Many nodes discovered using molecular data are upheld, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea (elephants) and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats). Our tree suggests that Placentalia first split into Xenarthra and Epitheria; extinct New World species are the oldest members of Afrotheria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Leary, Maureen A -- Bloch, Jonathan I -- Flynn, John J -- Gaudin, Timothy J -- Giallombardo, Andres -- Giannini, Norberto P -- Goldberg, Suzann L -- Kraatz, Brian P -- Luo, Zhe-Xi -- Meng, Jin -- Ni, Xijun -- Novacek, Michael J -- Perini, Fernando A -- Randall, Zachary S -- Rougier, Guillermo W -- Sargis, Eric J -- Silcox, Mary T -- Simmons, Nancy B -- Spaulding, Michelle -- Velazco, Paul M -- Weksler, Marcelo -- Wible, John R -- Cirranello, Andrea L -- New York, N.Y. -- Science. 2013 Feb 8;339(6120):662-7. doi: 10.1126/science.1229237.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomical Sciences, School of Medicine, HSC T-8 (040), Stony Brook University, Stony Brook, NY 11794-8081, USA. maureen.oleary@stonybrook.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23393258" target="_blank"〉PubMed〈/a〉

    Purification, cloning, and characterization of an arylsulfotransferase from the anaerobic bacterium Eubacterium rectale IIIH (2000)

    Notes: A bacterium, Eubacterium rectale IIIH, which possessed arylsulfotransferase (ASST) activity was isolated from human feces. The ASST gene (astA) was cloned and the corresponding protein partially characterized. This gene shows only moderate homology to the previously sequenced ASST genes of Klebsiella and Enterobacter, which are very closely related to each other. Journal of Industrial Microbiology & Biotechnology (2000) 25, 305–309.

    Effects of Soil Hydraulic and Transport Parameter Uncertainty on Predictions of Solute Transport in Large Lysimeters (2013)
    Soil Science Society of America (SSSA)
    Details
    Publication Date: 2013-02-22
    Description: Advanced numerical simulation models can potentially help improve guidelines for irrigation and salinity management. Many simulation model parameters have considerable uncertainty, and ideally that uncertainty should be reflected in model predictions and recommendations. In this work, we investigate solute transport predication intervals that can be generated by propagating model parameter uncertainty using Monte Carlo techniques. Flow and transport is simulated with a standard numerical model, while soil parameters and their uncertainty are estimated with pedotransfer functions. Generalized global sensitivity coefficients are computed to determine the parameters having the greatest impact on transport prediction and uncertainty. Simulations are compared with Br transport measured under unsaturated conditions in large lysimeters packed with clayey soil materials. In a 48 cm tall, homogeneous soil profile, model prediction intervals provided a reasonably good description of a single, relatively "noisy" breakthrough curve. In replicated 180 cm tall, layered soil profiles, model structural errors limited the accuracy of the prediction intervals under one irrigation water treatment, whereas under another treatment the predictions tracked the time course of the data reasonably well but tended to overestimate solute concentrations. The width of the prediction intervals tended to be small relative to the range of transport variability that existed across replicated lysimeters, particularly at shallow depths. Additional work aimed at operational field testing of model prediction uncertainty is needed if advanced water management models are to reach their full potential.
