Our research proposal to use proteomics to investigate sperm modification within the female reproductive tract, along with its evolutionary divergence and reproductive isolation consequences, is recommended for funding by the NSF. This work is a collaboration between CRE members Steve Dorus, Scott Pitnick, John Belote and PhD student Emma Whittington, along with Mariana Wolfner of Cornell University and Tim Karr of the Kyoto Institute of Technology.
Brian’s research combined investigations from the field, laboratory and artificial pastures in the greenhouse on the LSC rooftop to explore the evolutionary maintenance of alternative male reproductive tactics in the yellow dung fly, Scathophaga stercoararia. We wish Brian great success as he begins a killer postdoctoral fellowship at UC, Davis with Frank Zalom of the Department of Entomology and Nematology.
Emma, a PhD student in the CRE, is the first student to receive this prestigious fellowship, made possible by a generous gift to the SU Biology Department from former faculty member Marilyn Kerr. Color us proud.

The recent Nature paper was covered by numerous media outlets, but none better than that by science writer and journalist Ed Yong of The Atlantic: article Thanks, Ed! We are huge fans of your work.
Collaborative research by CRE members Pitnick, Belote and Puniamoorthy, together with CRE alumni Lüpold, Manier and othersreveal that the giant sperm some Drosophila may be the most extreme ornaments in all of nature and demonstrate how their existence challenges theories explaining the intensity of sexual selection, mating-system evolution and the fundamental nature of sex differences. The study also combined quantitative genetic analyses of interacting sex-specific traits in D. melanogaster with comparative analyses of the condition dependence of male and female reproductive potential across species with varying ornament size to reveal complex dynamics that may underlie sperm-length evolution.
CRE Investigators Discuss the Importance of Hands-on Mentorship in the Laboratory and the Classroom at a Syracuse University Alumni Event in Philadelphia
Scott Pitnick and Steve Dorus discuss sperm biology, the genesis of the CRE and the important role played by motivated undergraduates in its research mission with Syracuse University alumni in the Egypt Room of Penn’s Museum of Archeology and Anthropology. The event was well attended by a diverse mix of accomplished SU alumni and also included inspiring talks by SU Biology alumnus Laura Feldman and SU Interim VP for Research Peter Vanable.
Liz Droge-Young has been named the recipient of a 2016 All-University Dissertation Prize from The College of Arts & Sciences. She will be presented with a certificate and a check during the Doctoral Hooding Ceremony on May 13, 2016.
Liz Droge-Young, a CRE PhD student, has her recent publication in Behavioral Ecology covered by Syracuse University news
Her research suggests that the desiccating environment of stored grain facilities underlies the evolution of extreme promiscuity by female red flour beetles, with females mating with many males each day in order to harvest moisture from their ejaculates. In something of a sexual conflict twist, all of this mating appears to come at a cost to males – http://news.syr.edu/journal-publishes-doctoral-candidates-findings-on-beetle-promiscuity-60370/
