GrossDEB-9903904Understanding the relationships between species diversity and productivity is fundamental to the management and preservation of biodiversity. Despite years of study and intense theoretical interest however, the overall relationship remains poorly understood. This project will examine this relationship experimentally in a field project that will manipulate soil resource heterogeneity and examine the effect on species diversity. Diversity will also be manipulated by a seed addition treatment. These experiments will examine how resource heterogeneity can influence changes in species diversity that parallel similar patterns in overall productivity. It will provide a test of one of the basic hypotheses explaining productivity-diversity relationships.

GrossDEB-9903904了解物种多样性和生产力之间的关系是管理和保护生物多样性的基础。 然而，尽管多年的研究和强烈的理论兴趣，整体关系仍然知之甚少。 本计画将在实地计画中以实验方式检视此一关系，以操控土壤资源异质性，并检视其对物种多样性的影响。 多样性也将通过种子添加处理来操纵。 这些实验将研究资源异质性如何影响物种多样性的变化，这些变化与整体生产力的相似模式平行。 它将提供一个测试的基本假设解释生产力多样性的关系。
