IntroductIon The Southern Stingray, Hypanus americanus (previously Dasyatis americana), is a common whiptail stingray of western Atlantic coastal waters, including the Caribbean Sea and the Gulf of Mexico (Robins and Ray 1986, Last et al. 2016). Although this stingray is important to ecotourism in the Caribbean Sea (Corcoran 2006) and is routinely captured as bycatch within southern trawl fisheries (Graham et al. 2009), it is currently not under direct threat of overexploitation. While biological and behavioral information has been reported for this species based on studies of both captive (Henningsen and Leaf 2010) and wild individuals (Funicelli 1975, Chapman et al. 2003, Corcoran 2006, Semeniuk et al. 2007), significant gaps in life history remain. The species is considered data deficient by the International Union for Conservation of Nature (IUCN) (Grubbs et al. 2016). Age information forms the basis for calculations of growth and mortality rates, as well as productivity, making it one of the most important variables for estimating a population’s status, including assessments of the risks associated with exploitation (Cailliet and Goldman 2004). Henningsen and Leaf (2010) provided initial age data on captive southern stingrays; however, no complementary work has been conducted on wild populations. Since growth in captivity may not accurately reflect growth in the wild (Mohan 1996), the goal of the present study was to provide preliminary age— at—width estimates of wild caught specimens using counts of growth bands from vertebral centra.
南方黄貂鱼，Hypanus americanus(以前的Dasyatis americana)，是大西洋西部沿海水域常见的鞭尾黄貂鱼，包括加勒比海和墨西哥湾(Robins和Ray 1986, Last et al. 2016)。虽然这种黄貂鱼对加勒比海的生态旅游很重要(Corcoran 2006)，并且经常在南部拖网渔业中作为副渔获物被捕获(Graham et al. 2009)，但目前它没有受到过度开发的直接威胁。虽然根据圈养个体(Henningsen and Leaf 2010)和野生个体(Funicelli 1975, Chapman et al. 2003, Corcoran 2006, Semeniuk et al. 2007)的研究报告了该物种的生物学和行为信息，但在生活史上仍然存在重大差距。国际自然保护联盟(IUCN)认为该物种数据不足(Grubbs et al. 2016)。年龄信息是计算增长率和死亡率以及生产率的基础，使其成为估计人口状况的最重要变量之一，包括评估与剥削有关的风险(Cailliet和Goldman, 2004年)。Henningsen和Leaf(2010)提供了圈养南方黄貂鱼的初始年龄数据;然而，没有对野生种群进行补充研究。由于圈养的生长可能不能准确地反映野生的生长(Mohan 1996)，本研究的目的是通过脊椎中心的生长带计数，对野生捕获的标本提供初步的宽度年龄估计。

Grand Bay National Estuarine Research Reserve (GBNERR) is a 7500 ha protected area in Jackson County, MS. In 2005, a levee breach at a fertilizer manufacturing facility released highly acidic and phosphate—rich wastewater into the reserve. A second spill occurred in September 2012 following Hurricane Isaac. We used orthophosphate (PO4 3—) concentrations to categorize the 2 events, post— events, and non—impact periods between the 2 spills. We examined spatial and temporal patterns in nutrients, chlorophyll, pH, and other parameters within and between monitoring stations. After the first event, pH at the Bangs Lake water quality station decreased to 3.7 and PO4 3— increased to over 4 mg P/l. Orthophosphate returned to background concentrations near the detection limit after approximately one year. Sampling 3 weeks after Hurricane Isaac showed PO4 3— concentrations over 1 mg P/l in Bangs Lake. Elevated PO4 3— levels were detected at other monitoring locations for 3—5 months, depending on distance from the fertilizer facility. Multiple comparison tests of trends within stations showed that both events had statistically similar PO4 3— concentrations, although the magnitudes and the time to return to baseline concentrations differed between stations. Temporal patterns of other nutrients had apparent long—term trends, particularly chlorophyll a, which showed an increase from 18—56% depending on station. This study provides a rare description of decadal water quality trends in a shallow, temperate estuary in response to discrete spill events. The results provide new information on the effects of phosphorus inputs to nitrogen—limited systems, having management implications for Gulf Coast estuaries.
