  DNA barcoding a taxonomically complex hemiparasitic genus reveals deep divergence between ploidy levels but lack of species-level resolution 

  Wang, Xumei; Gusarova, Galina; Ruhsam, Markus; de Vere, Natasha; Metherell, Chris; Hollingsworth, Peter M.; Twyford, Alex D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-24)

  DNA barcoding is emerging as a useful tool not only for species identification but also for studying evolutionary and ecological processes. Although plant DNA barcodes do not always provide species-level resolution, the generation of large DNA barcode data sets can provide insights into the mechanisms underlying the generation of species diversity. Here, we study evolutionary processes in taxonomically ...

  Developing an observational design for epibenthos and fish assemblages in the Chukchi Sea 

  Iken, Katrin; Mueter, Franz J.; Grebmeier, Jacqueline M.; Cooper, Lee W.; Danielson, Seth L.; Bluhm, Bodil (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-14)

  In light of ongoing, and accelerating, environmental changes in the Pacific sector of the Arctic Ocean, the ability to track subsequent changes over time in various marine ecosystem components has become a major research goal. The high logistical efforts and costs associated with arctic work demand the prudent use of existing resources for the most comprehensive information gain. Here, we compare ...

  <p><i>Introduction</i>: The complement system is essential for an adequate immune response. Much attention has been given to the role of complement in disease. However, to better understand complement in pathology, it is crucial to first analyze this system under different physiological conditions. The aim of the present study was therefore to investigate the inter-individual variation in complement ...

  Nonlocal damage mechanics for quantification of health for piezoelectric sensor 

  Habib, Anowarul; Shelke, Amit; Amjad, U; Pietsch, Ullrich; Banerjee, S (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-18)

  In this paper, a novel method to quantify the incubation of damage on piezoelectric crystal is presented. An intrinsic length scale parameter obtained from nonlocal field theory is used as a novel measure for quantification of damage precursor. Features such as amplitude decay, attenuation, frequency shifts and higher harmonics of guided waves are commonly-used damage features. Quantification of the ...

  How Is Adolescent Bone Mass and Density Influenced by Early Life Body Size and Growth? The Tromsø Study: Fit Futures—A Longitudinal Cohort Study From Norway 

  Evensen, Elin; Skeie, Guri; Wilsgaard, Tom; Christoffersen, Tore; Dennison, Elaine; Furberg, Anne-Sofie; Grimnes, Guri; Winther, Anne; Emaus, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-30)

  The effect of birth weight and childhood body mass index (BMI) on adolescents’ bone parameters is not established. The aim of this longitudinal, population‐based study was to investigate the association of birth weight, childhood BMI, and growth, with adolescent bone mass and bone density in a sample of 633 adolescents (48% girls) from The Tromsø Study: Fit Futures. This population‐based cohort study ...
