Goodman Department of Biology University of North Carolina, AshevilleWhy is conservation of biodiversity important?: Why is conservation of biodiversity important? 6th Mass Extinction 20% or more species will disappear by 2020 10-100 million living organisms Only 1.4 million describedWhy should preservation of species be our responsibility?: Why should preservation of species be our responsibility? Primary causes of species declines are Habitat destruction Pollution Introduction of exotic speciesWhy study this species?: Why study this species? S. septentrionalis listed as “significantly rare” in NC Estimated 21-100 extant populationsEcology: Ecology Life-history is vague Only research conducted by IJ Cantrall, 1940’s, in MichiganHistorical range map: Historical range map TJ Walker, www.buzz.ifas.ufl.eduWhat is Scudderia septentrionalis?: What is Scudderia septentrionalis? Ensifera Katydids and Crickets Tettigoniidae Katydids Phaneropterinae False Katydids Scudderia septentrionalis Northern Bush KatydidsWhat type of research was conducted?: What type of research was conducted? Populations located homing in on loud species-specific calls Transects driven or walked to count populations Males captured with black lightMap of Western North Carolina: Map of Western North CarolinaWhat type of research was conducted?: What type of research was conducted? Insects are poikilothermic Temperature variation studies used sound analysis software to measure rate changesSonograms of male mating song: 16.4 °C 20kHz 5kHz 20kHz 5kHz 2 sec 2 sec Sonograms of male mating song 23.3 °C Ticks BuzzesRate of Ticking as a Function of Temperature: Rate of Ticking as a Function of TemperatureRate of Buzzing as a Function of Temperature: Rate of Buzzing as a Function of TemperatureIn Summary: In Summary Results 2 extant populations Historical sites unconfirmed Calling song studies Questions Is this species at edge of range or declining? Will our research aid in the preservation of this species? Save the katydids!!Acknowledgements: Acknowledgements Research funded by US Forest Service T.G. Forrest T.J.
