    Many cephalopods exhibit remarkable dermal iridescence, a component of their complex, dynamic camouflage and communication. In the species Euprymna scolopes, the light-organ iridescence is static and is due to reflectin ...
  • Development and validation of a real-time quantitative PCR assay for the detection and quantification of Perkinsus marinus in the Eastern oyster, Crassostrea virginica

    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 ...
  • 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, ...
  • Golgi cells operate as state-specific temporal filters at the input stage of the cerebellar cortex 

    Heine, Shane A.; Highstein, Stephen M.; Blazquez, Pablo M. (Society for Neuroscience, 2010-12-15)
    Cerebellar processing of incoming information begins at the synapse between mossy fibers and granule cells, a synapse that is strongly controlled through Golgi cell inhibition. Thus, Golgi cells are uniquely positioned to ...
  • 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 ...
