Reproductive output and telomere dynamics following calcium supplementation in wild Tree Swallows (Tachycineta bicolor)
<p>This data was the result of an experiment investigating whether biologically relevant differences in reproductive investment influence fitness in a wild bird species. We employed calcium supplementation to experimentally modify reproductive output in Tree Swallow mothers and offspring and we used telomere dynamics during the breeding season as a proxy for fitness. <span>To confirm that calcium supplementation positively impacts reproductive parameters at our study site, we initiated a 4-year trial of calcium supplementation with our Tree Swallow study population. In the following two breeding seasons, we used calcium supplementation to experimentally alter reproductive output and measured telomere length in mothers immediately before egg-laying and shortly before fledging to determine the direct relationship between reproductive investment and telomere shortening in this species. </span>Our study includes one hundred eighty-eight nests initiated and monitored over six breeding seasons. </p>

Reproductive output: Traits: Competition and Resource Reduction for Five Grass Species Grown in Monoculture and Competition in Soils with Different Nitrogen Availabilities
This experiment was designed to determine the relationships between plant traits, successional status, and resource reduction for five grass species that were grown for three years in monoculture in replicated field plots on soils prepared to have different availabilities of nitrogen. It also determines the results of competition experiments among various combinations of these species as well as the differing feedback effects of each species on soil nitrogen mineralization rates. All of this work has motivated the desire to more fully understand the mechanisms of interactions among plants and their resources, in the belief that this might eventually allow predictions of the dynamics, diversity, and composition of plant communities.
Reproductive output--number of flowering heads: The Diversity and Abundance of Prairie Plant Communties
This study is divided into six experiments that test the influence of many factors on the diversity and abundance of prairie plant communities. Each "community" is a 2.25 meter square plot seeded with the same amount of seeds from 59 different species of plants. The first experiment is a nitrogen-fire-water factorial. The second experiment is a nitrogen-pH factorial. The third experiment is a nitrogen gradient and the fourth experiment is a nitrogen gradient with a diversity of seeds added each year. The fifth experiment is a disturbance gradient and the last experiment has three levels of soil heterogeneity (variance from the mean) for both nitrogen and pH. See trmte86, trmte103, trmte104, trmte105, trmte106, trmte107 for plot layout.
