一些底栖存款饲养者的原位摄食率可以通过用荧光颗粒标记沉积物并使用这些颗粒通过动物的肠道追踪摄入的物质来确定，而不需要收集粪便。这项技术被应用到polychaeteNereis successfully，并表明，摄食率，表示为单位体重摄入的材料，随着温度的增加和身体大小的下降。aN每年总的沉积物和碎屑摄入量。北卡罗来纳州博福特附近盐沼中的一群琥珀，估计为5公斤干物质m-2，是报告的盐沼表层动物存款饲养者的4倍多。*** 直接支持 *** A01 BY 009 00005
In situ ingestion rates of some infaunal deposit feeders can be determined without collecting feces by labeling the sediment with fluorescent particles and using these to trace ingested material through the gut of the animals. This technique was applied to the polychaeteNereis succinea and showed that ingestion rate, expressed as material ingested per body weight, increased with temperature and decreased with body size. Total annual ingestion of sediment and detritus for aN. succinea population in a salt marsh near Beaufort, N.C., was estimated to be 5 kg of dry material m−2, more than 4 times that reported for salt marsh epifaunal deposit feeders. *** DIRECT SUPPORT *** A01BY009 00005
