To determine the correlation between plasma iron concentrations and gastric pH in a population of captive Atlantic bottlenose dolphins (Tursiops truncatus).
6 adult female dolphins that ranged from 16 to 30 years of age.
Blood and gastric samples were collected from each dolphin to allow measurement of plasma iron concentrations and gastric pH, respectively. Samples were collected each month for 12 months.
Within each dolphin, plasma iron concentrations and gastric pH did not differ significantly over time. There was a strong negative correlation (r = -0.85) between plasma iron concentration and gastric pH, which suggested that dolphins with a lower gastric pH had a higher plasma iron concentration.
Analysis of results reported here suggested that gastric pH may play an important role in iron absorption in dolphins.
确定圈养的大西洋宽吻海豚（瓶鼻海豚）群体中血浆铁浓度与胃pH值之间的相关性。
6只年龄在16至30岁之间的成年雌性海豚。
从每只海豚采集血液和胃样本，分别用于测量血浆铁浓度和胃pH值。每月采集样本，持续12个月。
在每只海豚体内，血浆铁浓度和胃pH值随时间没有显著差异。血浆铁浓度与胃pH值之间存在强烈的负相关（r = -0.85），这表明胃pH值较低的海豚血浆铁浓度较高。
对这里报告结果的分析表明，胃pH值可能在海豚铁吸收中起重要作用。
