The Nutritional Value of Sediment to Deposit Feeders

这项研究的主要概念是， 河口碎屑的春季脉冲组合 沉积物和相对较低的温度使产量最大化 动物的生物量。 沉积物的营养价值是 假设是低的，除了刚刚加入碎屑后， 在春天 这项研究将评估季节性变化， 实验条件下沉积物的营养价值 变化的温度和碎屑添加;它将寻求 了解沉积物营养价值的变化。 的 将沉积物中的碳和氮转化为动物肉， 与碎屑的转化效率相比。 的 缺氧区作为限制深度的一个因素的重要性 还将调查食物供应情况。

The principal concept of this research is that the combination of a spring pulse of detrital addition to estuarine sediments and relatively low temperatures maximize the production of animal biomass. The nutritive value of the sediment is hypothesized to be low, except just after the detrital addition in the spring. This study will assess seasonal changes in the nutritional value of sediment under experimental conditions of varying temperature and detrital addition; it will seek to understand how sediment nutritional value changes. The conversion of sediment carbon and nitrogen to animal flesh will be compared with the conversion efficiency from detritus. The importance of the anoxic zone as a factor limiting the depth of feeding access will also be investigated.
