My study is designed to ascertain how environmental heterogeneity, intraspecific competition, and variation among individuals interact to influence the initial spatial distribution and establishment of C. nauseosus seedlings in the sand-dune ecosystem at Mono Lake, CA. I will test the hypothesis that environmental heterogeneity will cause C. nauseosus seeds to be unevenly distributed in the landscape, and microsites promoting seed retention will not necessarily promote seedling survival. I will also test whether intraspecific variation among seedling size and/or time of emergence interact with density to influence a seedling?s competitive ability and survival within aggregations. Finally, field experiments will be conducted to assess how variation in seedling emergence time and initial seedling size interact with environmental heterogeneity to influence seedling establishment. The resources I use at SNARL are housing and computer access. I commute to my field site on the north shore of Mono Lake which is not within the reserve.
