Harlequin duck capture and liver EROD activity, USGS and the Alaska Department of Fish and Game, Prince William Sound, 1995-2014

These data are part of a population monitoring initiative under a series of directed research projects designed to elucidate the process of, and constraints recovery of Harlequin ducks in Prince William Sound post the Exon Valdez Oil Spill. Induction of cytochrome P4501A (CYP1A) in vertebrates occurs to a limited number of compounds, including polycyclic aromatic hydrocarbons such as those found in crude oil and have been used to evaluate compounds in many cases of environmental contamination, including that of the Exxon Valdez oil spill. Elevated CYP1A has been demonstrated Prince William Sound. The data presented here quantifies CYP1A induction by the amount of hepatic 7-ethoxyresorufinO-deethylase (EROD) activity, well-established method and is the same approach used in earlier Exxon Valdez studies and in similar studies of harlequin ducks and other sea ducks. These data contain capture data from 1995-2014 and results of EROD activity level analyses (1998,2000,2001,2002,2005,2009,2011,2013,2014).

本数据集隶属于一系列定向研究项目下的种群监测计划，该系列项目旨在阐明埃克森·瓦尔迪兹号油溢事故（Exxon Valdez Oil Spill）后，威廉王子湾（Prince William Sound）内丑鸭（Harlequin Ducks）种群的恢复过程及其限制因素。脊椎动物体内的细胞色素P4501A（cytochrome P4501A, CYP1A）诱导效应可被有限类别的化合物触发，其中包括原油中所含的多环芳烃（polycyclic aromatic hydrocarbons）类物质；该指标已被广泛应用于诸多环境污染事件的污染物评估，其中就包括埃克森·瓦尔迪兹号油溢事故。研究已证实威廉王子湾区域存在CYP1A水平升高的现象。本数据集通过检测肝脏7-乙氧基试卤灵O-脱乙基酶（7-ethoxyresorufin O-deethylase, EROD）的活性水平来量化CYP1A的诱导程度，该方法为成熟的标准检测手段，且与此前埃克森·瓦尔迪兹号相关研究，以及针对丑鸭与其他海鸭的同类研究所采用的方法一致。本数据集涵盖1995年至2014年的野捕记录，以及1998、2000、2001、2002、2005、2009、2011、2013、2014年的EROD活性水平分析结果。
