I have posted the code for the Arabidopsis thaliana life-cycle model published in the American Naturalist on GitHub. I hope it provides a useful resource to the community. Feel free to ask if you have questions. You can find the files here:
The first chapter of my dissertation is out in the February issue of the American Naturalist!
The goal of this work was to develop a modeling framework of how traits such as the timing of flowering and germination together determine composite traits like generation time. Since these traits are phenotypically plastic, the models account for both environmental and genetic variation. We applied this model to understand patterns of allelic variation across the geographic range of the model plant A. thaliana
In addition, two other papers that I am involved with came out or are coming out! Congratulations to Kathleen Donohue and Gabriela Auge for heading up these publications. One is an opinion piece in TREE on about how developmental threshold models can be applied to answering questions in evolutionary ecology. The second examines the relationship between primary and secondary dormancy in seeds and is coming out in seed science research!
PDFs of all papers listed here can be found on my publication page!
Two new germination publications from former Donohue Lab visitor Chunhui Zhang!!!
Light-dependent associations of germination timing with subsequent life-history traits and maternal habitats for 476 angiosperm species of the easter Tibetan Plateau grasslands Chunhui Zhang, Kun Liu, Wei Qi, Zhen Ma and Guozhen Du. Volume 24, Issue 3, pages 207-215, September 2014.
Additionally, a second paper just cam out this month in New Phytologist that utilized this same rich dataset. Full disclosure: I and several other former lab mates are coauthors on this one.
The community-level effect of light on germination timing in relation to seed mass: a source of regeneration niche differentiation. Chunhui Zhang, Charles Willis, Liana T. Burghardt, Wei Qi, Kun Liu, Paulo Filho, Zhen Ma, and Guozhen Du.New Phytologist. 2014. Volume 204, Issue 3, pages 496–506, November 2014.
My name is Liana T. Burghardt. I am a graduate student at Duke University in the lab of Kathleen Donohue. I am an evolutionary ecologist broadly interested in how the environment shapes the diversity of organisms in the world. Feel free to explore this website to get a feeling for the questions that fascinate me and the projects that my collaborators and I have undertaken to address these questions.
