  • Lack of growth enhancement by exogenous growth hormone treatment in yellow perch (Perca flavescens) in four separate experiments 

    Jentoft, Sissel; Topp, Nicole; Seeliger, Matthew; Malison, Jeffrey A.; Barry, Terence P.; Held, James A.; Roberts, Steven B.; Goetz, Frederick W. (2005-03-02)
    The effect of exogenous growth hormone (GH) treatment on the growth of juvenile yellow perch (Perca flavescens) was investigated in four experiments. In the first two experiments, juvenile yellow perch were reared at either ...
  • Lethal marine snow : pathogen of bivalve mollusc concealed in marine aggregates 

    Lyons, M. Maille; Ward, J. Evan; Smolowitz, Roxanna M.; Uhlinger, Kevin R.; Gast, Rebecca J. (2005-06-14)
    We evaluated marine aggregates as environmental reservoirs for a thraustochytrid pathogen, Quahog Parasite Unknown (QPX), of the northern quahog or hard clam, Mercenaria mercenaria. Positive results from in situ hybridization ...
  • Microstructural and biochemical characterization of the nanoporous sucker rings from Dosidicus gigas 

    Miserez, Ali; Weaver, James C.; Pedersen, Peter B.; Schneeberk, Todd; Hanlon, Roger T.; Kisailus, David; Birkedal, Henrik (2008-11-24)
    Recent interest in the development of environmentally benign routes to the synthesis of novel multifunctional materials has resulted in numerous investigations into structure-function relationships of a wide range of ...
  • A “mimic octopus” in the Atlantic : flatfish mimicry and camouflage by Macrotritopus defilippi 

    Hanlon, Roger T.; Watson, Anya C.; Barbosa, Alexandra (Marine Biological Laboratory, 2010-02)
    The sand-dwelling octopus Macrotritopus defilippi was filmed or photographed in five Caribbean locations mimicking the swimming behavior (posture, style, speed, duration) and coloration of the common, sand-dwelling flounder ...
  • New species longevity record for the northern quahog (=hard clam), Mercenaria mercenaria 

    Ridgway, Iain D.; Richardson, C. A.; Enos, Edward; Ungvari, Z.; Austad, S. N.; Philipp, E. E. R.; Csiszar, Anna (National Shellfisheries Association, 2011-04)
    Twenty-two large shells (>90 mm shell height) from a sample of live collected hard shell clams, Mercenaria mercenaria, from Buzzards Bay, Woods Hole, Cape Cod, MA, were subjected to sclerochronological analysis. Annually ...
  • Optimization of a GCaMP calcium indicator for neural activity imaging 

    Akerboom, Jasper; Chen, Tsai-Wen; Wardill, Trevor J.; Tian, Lin; Marvin, Jonathan S.; Mutlu, Sevinc; Calderon, Nicole Carreras; Esposti, Federico; Borghuis, Bart G.; Sun, Xiaonan Richard; Gordus, Andrew; Orger, Michael B.; Portugues, Ruben; Engert, Florian; Macklin, John J.; Filosa, Alessandro; Aggarwal, Aman; Kerr, Rex A.; Takagi, Ryousuke; Kracun, Sebastian; Shigetomi, Eiji; Khakh, Baljit S.; Baier, Herwig; Lagnado, Leon; Wang, Samuel S.-H.; Bargmann, Cornelia I.; Kimmel, Bruce E.; Jayaraman, Vivek; Svoboda, Karel; Kim, Douglas S.; Schreiter, Eric R.; Looger, Loren L. (Society for Neuroscience, 2012-10-03)
    Genetically encoded calcium indicators (GECIs) are powerful tools for systems neuroscience. Recent efforts in protein engineering have significantly increased the performance of GECIs. The state-of-the art single-wavelength ...
  • Potential for sound sensitivity in cephalopods 

    Mooney, T. Aran; Hanlon, Roger T.; Madsen, Peter T.; Christensen-Dalsgaard, Jakob; Ketten, Darlene R.; Nachtigall, Paul E. (2010-07)
    Hearing is a primary sense in many marine animals and we now have a reasonable understanding of what stimuli generate clear responses, the frequency range of sensitivity, expected threshold values and mecha-nisms of sound ...
  • Primary and secondary defences of squid to cruising and ambush fish predators : variable tactics and their survival value 

    Staudinger, Michelle D.; Hanlon, Roger T.; Juanes, Francis (2010-11-19)
    Longfin squid (Loligo pealeii) were exposed to two predators, bluefish (Pomatomus saltatrix) and summer flounder (Paralichthys dentatus), representing cruising and ambush foraging tactics, respectively. During 35 trials, ...
  • Quantification of cuttlefish (Sepia officinalis) camouflage : a study of color and luminance using in situ spectrometry 

    Akkaynak, Derya; Allen, Justine J.; Mathger, Lydia M.; Chiao, Chuan-Chin; Hanlon, Roger T. (2012-11-19)
    Cephalopods are renowned for their ability to adaptively camouflage on diverse backgrounds. Sepia officinalis camouflage body patterns have been characterized spectrally in the laboratory but not in the field due to the ...
  • Scientific names of organisms : attribution, rights, and licensing 

    Patterson, David J.; Egloff, Willi; Agosti, Donat; Eades, David; Franz, Nico; Hagedorn, Gregor; Rees, Jonathan A.; Remsen, David P. (BioMed Central, 2014-02-04)
    As biological disciplines extend into the ‘big data’ world, they will need a names-based infrastructure to index and interconnect distributed data. The infrastructure must have access to all names of all organisms if it ...
  • 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 ...
