The purpose of my study is to determine how environmental variation influences the distribution and establishment of Chrysothamnus nauseosus seedlings in the sand-dune ecosystem at Mono Lake, CA. I will investigate whether the spatial patterns of seed retention and seedling survival are related to explain the cause of the initial distribution of seedlings in the population. Studying seed retention and seedling survival independently will allow me to determine which life history stage is the most limiting during the recruitment process. I will also investigate how intraspecific variation in seed size interacts with density to determine which seed and seedling characteristics increase seedling survival in aggregations. Specifically, I will test whether seedlings derived from different size seeds have different competitive abilities. Finally, I will conduct a field experiment to assess how variation in seed emergence time and initial seedling size interacts with varying density environments to influence seedling survival. Determining which traits are correlated with seedling survival will establish what seedling characteristics promote successful seedling establishment
