    • Tactical decisions for changeable cuttlefish camouflage : visual cues for choosing masquerade are relevant from a greater distance than visual cues used for background matching 

      Buresch, Kendra C.; Ulmer, Kimberly M.; Cramer, Corinne; McAnulty, Sarah; Davison, William; Mathger, Lydia M.; Hanlon, Roger T. (Marine Biological Laboratory, 2015-10-01)
      Cuttlefish use multiple camouflage tactics to evade their predators. Two common tactics are background matching (resembling the background to hinder detection) and masquerade (resembling an uninteresting or inanimate object ...
    • Tactical release of a sexually-selected pheromone in a swordtail fish 

      Rosenthal, Gil G.; Fitzsimmons, Jessica N.; Woods, Kristina U.; Gerlach, Gabriele; Fisher, Heidi S. (Public Library of Science, 2011-02-09)
      Chemical communication plays a critical role in sexual selection and speciation in fishes; however, it is generally assumed that most fish pheromones are passively released since most fishes lack specialized scent glands ...
    • Target repurposing for neglected diseases 

      Pollastri, Michael P.; Campbell, Robert K. (2011-06-30)
      Infectious diseases are an enormous burden to global health, and since drug discovery is costly, those infectious diseases that affect the developing world are often not pursued by commercial drug discovery efforts. ...

      The digitization of biodiversity data is leading to the widespread application of taxon names that are superfluous, ambiguous or incorrect, resulting in mismatched records and inflated species numbers. The ultimate ...
    • The taxonomic significance of species that have only been observed once : the genus Gymnodinium (Dinoflagellata) as an example 

      Thessen, Anne E.; Patterson, David J.; Murray, Shauna A. (Public Library of Science, 2012-08-30)
      Taxonomists have been tasked with cataloguing and quantifying the Earth’s biodiversity. Their progress is measured in code-compliant species descriptions that include text, images, type material and molecular sequences. ...
    • Telomere-associated endonuclease-deficient Penelope-like retroelements in diverse eukaryotes 

      Gladyshev, Eugene A.; Arkhipova, Irina R. (2007-02-27)
      The evolutionary origin of telomerases, enzymes that maintain the ends of linear chromosomes in most eukaryotes, is a subject of debate. Penelope-like elements (PLEs) are a recently described class of eukaryotic retroelements ...
    • Temporal dietary shift in jellyfish revealed by stable isotope analysis 

      Javidpour, Jamileh; Cipriano-Maack, Ashlie N.; Mittermayr, Agnes; Dierking, Jan (Springer, 2016-04-10)

    • Temporal sampling, resetting, and adaptation orchestrate gradient sensing in sperm 

      Kashikar, Nachiket D.; Alvarez, Luis; Seifert, Reinhard; Gregor, Ingo; Jackle, Oliver; Beyermann, Michael; Krause, Eberhard; Kaupp, U. Benjamin (Rockefeller University Press, 2012-09-17)
      Sperm, navigating in a chemical gradient, are exposed to a periodic stream of chemoattractant molecules. The periodic stimulation entrains Ca2+ oscillations that control looping steering responses. It is not known how sperm ...
