Bat avoidance in the katydid genus Neoconocephalus
Kilmer, Mary K., 1983- (University of Missouri--Columbia, 2010)The hearing system of the katydid genus Neoconocephalus has two functions: intraspecific communication and predator (bat) avoidance. Male calls and bat cries differ spectrally and temporally. Katydids must recognize and ... -
Call synchrony and the evolutionary origins of leader preference in Neoconocephalus ensiger katydids /
Murphy, Megan, 1988- (University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Many species of acoustically communicating insects and anurans display a female preference for males producing their calls just ahead of those of their ... -
Dynamic dendritic compartmentalization as a potential mechanism for auditory stream segregation in insects [abstract]
Harmon, Anne; Schul, Johannes (University of Missouri--Columbia. Office of Undergraduate Research, 2007)The process of Auditory Stream Segregation (AudSS) allows animals to separate relevant acoustic signals from non-relevant signals by grouping them into useful perceptual objects. AudSS has been described extensively in ... -
The evolution of complex calls In meadow Katydids
Harness, Nathan Charles Eugene (University of Missouri--Columbia, 2018)Meadow Katydids (genera Orchelimum and Conocephalus) are a specious group often are found in habitats with several species within the group living in sympatry. They produce complex calls with two distinct phrases, "buzzing" ... -
Evolution of signal frequency in Neoconocephalus (Orthoptera: Tettigoniidae) : a study of perceptual and environmental sources of selection
Talwar, Malvika, 1977- (University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Mate-attraction signals offer an ideal opportunity to examine the sources of selection that shape traits and trait diversity, as they are very diverse ... -
The evolutionary significance of developmental plasticity in the communication system of Neoconocephalus triops (Orthoptera: tettigoniidae)
Beckers, Oliver M., 1975- (University of Missouri--Columbia, 2008)The katydid Neoconocephalus triops is a tropical species that extended its distribution range to North America. In North America, males display developmental plasticity in mating calls between reproductive generations: the ... -
Investigating an adaptive radiation in temperate Neoconocephalus
Frederick, Katherine H., 1982- (University of Missouri--Columbia, 2013)Evolution of communication system is seemingly complex requiring coevolution between sender and receiver mechanisms. Studying acoustic communication in the katydid genus Neoconocephalus (coneheaded katydids), I compare ... -
Mechanisms of call recognition in three sympatric species of Neoconocephalus (Orthoptera: Tettigoniidae) : asymmetrical interactions and evolutionary implications
Deily, Joshua Allen, 1976- (University of Missouri--Columbia, 2006)Scientists have debated the hypothesis of reinforcement. Nevertheless, recent empirical and theoretical work have dispelled doubts about its existence. Reinforcement is most often studied by establishing one of its predicted ... -
Population level genetic differentiation among temperate neoconocephalus katydids
Ney, Gideon, 1986- (University of Missouri--Columbia, 2017)Recent work indicates that radiation events may play a significant role in shaping species diversity across entire continents. Here we quantify population level genetic differentiation in several species of Neoconocephalus ... -
Sensory processing and the evolution of female preference in Neoconocephalus
Hartman, Garrett Andrew (University of Missouri--Columbia, 2013)While the importance of the female preference for exaggerated male traits is largely understood, the evolutionary origins remain under debate. During the evolution of the female preference for leading signals via a sensory ... -
Stimulus specific adaptation in the hearing system of Neoconocephalus katydids (insecta: Orthoptera)
Johnson, Luesoni D. (University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Stimulus Specific Adaptation (SSA) is a fundamental response that identifies novel signals within a repetitive background noise. It is well characterized ... -
Using simple nervous systems to investigate the neural basis of behavior
McClellan, Andrew; Schul, Johannes; Schulz, David; Zars, Troy Daniel (2010)The human brain is remarkable, both in the sense that it helps us with a lifetime of decisions and memories, but also that it allows us to contemplate how the brain itself works. One concludes, however, pretty quickly ...
