Project title: Effects of global climate change on rare plants. A major challenge for conservation biologists is predicting the fates of species in a rapidly changing climate of the 21st century. In the southeastern United States, rock outcrops support a distinctive flora that includes rare endemic plants, many of which are of conservation concern due to their restricted distributions and habitat destruction. Understanding the future fates of rare edaphic endemics is especially challenging because it’s unclear whether current distributions are limited by the specialized soils of outcrops, by climate, or by a combination of climate and soil. In this study, we ask two questions: 1) Can edaphic endemics live outside of their current climate niche? 2) What is the relative importance of soil and climate in restricting the distribution of edaphic endemics? To answer these questions, the student will conduct seed transplant experiments with species in the genus Leavenworthia, which are being used a model organisms to understand the role of climate and soil in structuring geographic distributions of rare edaphic endemics. The student will establish seed germination and seedling experiments in germination incubators set to current and future climate scenarios. Each week, the student will record demographic data (germination, survival, and plant morphometrics) for seeds and seedlings, maintain experimental conditions, and enter demographic data into a Microsoft Excel database. Additionally, the student may participate in measuring the microclimate of glades to better understand the environmental conditions these plants experience. Students can participate in the analysis and preparation of manuscripts based on the experimental data.
