      Evolution drives and is driven by demography. A genotype moulds its phenotype’s age-patterns of mortality and fertility in an environment; these two patterns in turn determine the genotype’s fitness in that environment. ...
    • The diversity of sulfide oxidation and sulfate reduction genes expressed by the bacterial communities of the Cariaco Basin, Venezuela

      Qualitative expression of dissimilative sulfite reductase (dsrA), a key gene in sulfate reduction, and sulfide:quinone oxidoreductase (sqr), a key gene in sulfide oxidation was investigated. Neither of the two could be ...
    • Diversity of the marine cyanobacterium Trichodesmium : characterization of the Woods Hole culture collection and quantification of field populations 

      Hynes, Annette Michelle (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-09)
      Trichodesmium is a colonial, N2-fixing cyanobacterium found in tropical oceans. Species of Trichodesmium are genetically similar but several species exist together in the same waters. In order to coexist, Trichodesmium ...

      Species diversity, phylogenetic affiliations, and environmental occurrence patterns of thiosulfate-oxidizing marine bacteria were investigated by using new isolates from serially diluted continental slope and deep-sea ...
    • Diving behavior of the reef manta ray links coral reefs with adjacent deep pelagic habitats 

      Braun, Camrin D.; Skomal, Gregory B.; Thorrold, Simon R.; Berumen, Michael L. (Public Library of Science, 2014-02-06)
      Recent successful efforts to increase protection for manta rays has highlighted the lack of basic ecological information, including vertical and horizontal movement patterns, available for these species. We deployed pop-up ...

    • Does fish larval dispersal differ between high and low latitudes? 

      Leis, Jeffrey M.; Caselle, Jennifer E.; Bradbury, Ian R.; Kristiansen, Trond; Llopiz, Joel K.; Miller, Michael J.; O'Connor, Mary I.; Paris, Claire B.; Shanks, Alan L.; Sogard, Susan M.; Swearer, Stephen E.; Treml, Eric A.; Vetter, Russell D.; Warner, Robert R. (2013-02)
      Several factors lead to expectations that the scale of larval dispersal and population connectivity of marine animals differs with latitude. We examine this expectation for demersal shorefishes, including relevant ...
    • Does the marine biosphere mix the ocean? 

      Dewar, William K.; Bingham, Rory J.; Iverson, R. L.; Nowacek, Douglas P.; St. Laurent, Louis C.; Wiebe, Peter H. (Sears Foundation for Marine Research, 2006-07)
      Ocean mixing is thought to control the climatically important oceanic overturning circulation. Here we argue the marine biosphere, by a mechanism like the bioturbation occurring in marine sediments, mixes the oceans as ...
