    • Community structure of marine sedimentary protists in relation to flow and grain size 

      Shimeta, Jeff; Gast, Rebecca J.; Rose, Julie M. (Inter-Research, 2007-06-20)
      Populations of unicellular, marine sedimentary protists are constrained by a variety of physical environmental factors, but influences of flow regime have rarely been studied. We compared community structure among 3 subtidal ...

      Schedules of survival, growth and reproduction are key life-history traits. Data on how these traits vary among species and populations are fundamental to our understanding of the ecological conditions that have shaped ...
    • The comparative "systems" approach to HAB research 

      Anderson, Donald M.; Pitcher, Grant C.; Estrada, Marta (Oceanography Society, 2005-06)
      Experimental and comparative methods have been referred to as “the two great methods of science” (Mayr, 1982). To reach valid scientific conclusions, the processes of interest should be studied through repeated investigations, ...
    • Comparative AMS radiocarbon dating of pretreated versus non-pretreated tropical wood samples 

      Patrut, Adrian; von Reden, Karl F.; Lowy, Daniel A.; Mayne, Diana H.; Elder, Kathryn L.; Roberts, Mark L.; McNichol, Ann P. (2009-10)
      Several wood samples collected from Dorslandboom, a large African baobab (Adansonia digitata L.) from Namibia, were investigated by AMS radiocarbon dating subsequent to pretreatment and, alternatively, without pretreatment. ...
    • Comparative analyses of aryl hydrocarbon receptor structure and function in marine mammals 

      Lapseritis, Joy M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2007-02)
      Marine mammals possess high body burdens of persistent organic pollutants, including PCBs and dioxin-like compounds (DLC). Chronic environmental or dietary exposure to these chemicals can disrupt the function of reproductive ...
    • A comparative analysis of marine mammal tracheas 

      Moore, Colby D.; Moore, Michael J.; Trumble, Stephen J.; Niemeyer, Misty E.; Lentell, Betty J.; McLellan, William A.; Costidis, Alexander M.; Fahlman, Andreas (2013-11)
      In 1940, Scholander suggested that stiffened upper airways remained open and received air from highly compressible alveoli during marine mammal diving. There are little data available on the structural and functional ...
    • Comparative analysis of methane-oxidizing archaea and sulfate-reducing bacteria in anoxic marine sediments 

      Orphan, V. J.; Hinrichs, Kai-Uwe; Ussler, W.; Paull, Charles K.; Taylor, L. T.; Sylva, Sean P.; Hayes, John M.; DeLong, Edward F. (American Society for Microbiology, 2001-04)
      The oxidation of methane in anoxic marine sediments is thought to be mediated by a consortium of methane-consuming archaea and sulfate-reducing bacteria. In this study, we compared results of rRNA gene (rDNA) surveys and ...
