Cornell Ecology and Evolutionary Biology
the Geber Lab


Note to Prospective Students
Graduate students in the lab work on a range of evolutionary and ecological questions and on projects that are most often independent of my research. Projects have focused on the determinants of species distributions at ecological and evolutionary time scales, determinants of genetic variation within and among populations, adaptation with respect to biotic and abiotic environments, meta-population dynamics, and behavioral ecology.  Students have worked on plants and animals.

Postdocs often join in my own research and expand on the work in directions of particular interest. Postdocs have also brought independent funding for their own research projects.

Undergraduate students often begin as assistants on my research or that of my graduate students and postdocs. Some students also develop independent projects that often lead to honors theses. Examples of independent projects include
  • Variation in photosynthetic physiology between flower color morphs of Dame's Rocket (R. Gonzalez)
  • Population differentiation in the range expansion of a native maritime plant (J. Brauer)
  • Hybrid inviability in F1 between two subspecies of Clarkia xantiana (A. Senft)
  • Evolutionary response to artificial selection on flower size and implications for breeding system evolution in Clarkia xantiana (S. Markovich, C. Noss)
  • Water potential and gas exchange differences among genotypes of Polygonum arenastrum (A. Sultana, D. Steinberg)
