ABSTRACT 97-07641 Kilham and Kreeger Collaborative Research: Effects of Seston Quantity and Quality on Zooplankton in a Mesotrophic Lake Zooplankton are small animals that abound in lakes where they serve as critical links in the food chain. Zooplankton feed on microscopic plant, animal and dead organic material, called seston. Like most animals, they are known to be negatively affected by poor food availability and quality. This research will use microencapsulation technology to produce a variety of artificial seston particles containing specific biochemicals. These will be analyzed for their suitability as zooplankton diets by measuring digestibility. The best particles will be delivered to zooplankton as nutritional supplements to an otherwise poor diet, and any increase in animal performance will be definitively attributed to the specific biochemical in the supplement. Results of this study will help launch a broader research program to examine how natural, mixed populations of zooplankton can be nutritionally limited, a topic widely perceived to be a fundamental hurdle to an improved understanding of aquatic ecology.

摘要97-07641 Kilham和Kreeger合作研究：萨斯顿量和质量对浮游动物浮游生物的浮游动物的影响是湖泊中的小动物，在湖泊中充斥着食物链中的关键联系。 浮游动物，动物和死有机材料，称为塞斯顿。 像大多数动物一样，众所周知，它们会受到较差的食物可用性和质量的负面影响。 这项研究将使用微囊化技术生产包含特定生化物的各种人造塞斯顿颗粒。 这些将通过测量消化率来分析它们作为浮游动物饮食的适用性。 最好的颗粒将作为营养补充剂作为原本不良的饮食传递给浮游动物，动物性能的任何提高都将确定归因于补充剂中的特定生化。 这项研究的结果将有助于启动更广泛的研究计划，以研究如何在营养上有限的自然，混合的浮游动物，这是一个广泛认为是对水生生态学的理解的基本障碍。
