David W. Zeh

Professor of Biology Emeritus | Vice Provost, Graduate Education | Dean, Graduate School, Emeritus He/him/his

Summary

David Zeh retired in 2022 after 23 years as a faculty member of the Department of Biology. He served as Department Chair from 2011 to 2014 and was appointed Vice Provost, Graduate Education/Dean of the Graduate School in 2014. In this latter role, he originated or played key roles in numerous strategic initiatives that supported graduate faculty and graduate students in the Biology master’s program and Biology-affiliated interdisciplinary graduate programs (EECB, Hydrologic Sciences and Neuroscience). These initiatives included establishment of: 1) the Office of Postdoctoral Affairs, 2) recruitment and graduate fellowship programs, such as Gradventure, GradFIT and Nevada DRIVE, 3) graduate scholarship programs, such as the Graduate Dean Fellowship and Scholarship program, the Raymond H. Berner Graduate Scholarship program and the Robert E. Dickenson Scholarship program, and 4) faculty and graduate student training programs, such as Mentoring Mentors, Effective Teaching Practices in Higher Education (Grad 702/703) and the Three Minute Thesis at Nevada. As principal investigator, Dr. Zeh led a team of interdisciplinary faculty to secure the first-ever  to the University. During David Zeh’s tenure as Graduate Dean, overall graduate enrollment increased 30%, doctoral enrollment increased 41%, and graduate enrollment for American Indian/Alaska Native, Asian, Black, Hispanic and International students increased 56%, 73%, 142%, 120% and 34%, respectively. These gains in enrollment and diversity were paralleled by increases in student performance, as evidenced, for example, by an order of magnitude increase in the number of 推荐杏吧原创 students awarded fellowships from the NSF Graduate Research Fellowship Program.

Research interests

I carried out theoretical and empirical research in the fields of sexual selection, speciation and evolutionary epigenetics, and trained undergraduate and graduate students in interdisciplinary approaches to research in ecology and evolution. These investigations, often conducted in collaboration with Jeanne Zeh, led to a range of novel contributions, including elucidating the importance of:

  • Genomic conflict in the evolution of polyandry as a female mating strategy to avoid genetic incompatibility
  • Reproductive mode in determining the relative evolutionary rates of pre- versus post-zygotic reproductive isolation and thus the tempo and mode of speciation
  • Strict maternal inheritance of mitochondria as a constraint on male adaptation
  • Physiological stress in disrupting epigenetic silencing of transposable elements, a process that can promote biological diversification through non-adaptive or maladative colonization of new adaptive peaks
  • Intergenerational epigenetic inheritance in resolving the lek paradox
  • Epigenetic inheritance in enabling and/or constraining populations to respond to climate change-induced environmental challenges
