9412304 Patterson This project investigates the balance between heterotrophy and symbiotic autotrophy in sponges, a topic that we know very little about. Through a series of laboratory experiments the investigators will determine the effects of ecosystem (freshwater vs. marine), sponge morphology, and energy regime on the extent of sponge heterotrophy and autotrophy. The techniques employed are novel and include flow cytometry and DNA to RNA ratios. This study will result in new fundamental understanding of the biology of sponges and their role in ecosystems. The results of this study can be applied to ecosystem management, especially for those ecosystems in which sponges are important, including such diverse systems as Lake Baikal and the Florida Keys.

9412304 Patterson 该项目研究海绵异养和共生自养之间的平衡，这是一个我们知之甚少的话题。 通过一系列实验室实验，研究人员将确定生态系统（淡水与海洋）、海绵形态和能量状态对海绵异养和自养程度的影响。 所采用的技术很新颖，包括流式细胞术和 DNA 与 RNA 比率。 这项研究将对海绵生物学及其在生态系统中的作用产生新的基本认识。 这项研究的结果可应用于生态系统管理，特别是对于那些海绵发挥重要作用的生态系统，包括贝加尔湖和佛罗里达群岛等不同的系统。
