美洲新糠虾Neomysis americana(Smith,1873)原产于北美洲大西洋西海岸的浅海沃茨水域和河口。尽管重要的作用mysids如N。Americanaplay在河口生态系统作为消费者和猎物的更高的营养水平,有有限的信息如何代谢影响他们的空间生态和栖息地的要求。在美国马里兰州切萨皮克湾的支流中,先前的研究表明,夏季水温可以接近N的致死上限。美国。我们测量了N的人均代谢率(µ gO2 min-1)。本笃,MD,切萨皮克湾的一条支流附近的Patuxent河上游的美洲,在实验室中评估代谢反应的盐度和温度条件下,糠虾的经验,在自然栖息地。对代谢率的性别特异性和每日模式进行了量化。代谢率在夜间和白天之间没有差异,雄性和雌性之间的代谢率没有显著差异,妊娠雌性除外。在29 °C时,盐度2和8处理的代谢率最低,在22 °C时,盐度2处理的代谢率最高。只有温度具有统计学显著性,尽管出乎意料。本研究表明,N.美洲的温度和盐度条件是复杂的和可塑的,并且在现实的夏季温度和盐度条件下,代谢率可以变化3-4倍。随着环境条件的不断变化,了解糠虾的代谢反应,以现实的盐度和温度条件是必要的了解他们在温带河口的分布。
The mysidNeomysis americana(Smith, 1873) is native to shallow shelf waters and estuaries of the western Atlantic coast of North America. Despite the important role mysids such asN. americanaplay in estuarine ecosystems as both consumers and as prey for higher trophic levels, there is limited information on how metabolism influences their spatial ecology and habitat requirements. In tributaries of Chesapeake Bay, MD, USA, previous research has shown that summer water temperatures can approach the lethal upper tolerance limit forN. americana. We measured the per capita metabolic rate (µgO2min–1) ofN. americanafrom the upper Patuxent River near Benedict, MD, a tributary of Chesapeake Bay in the laboratory to evaluate the metabolic response to salinity and temperature conditions that mysids experience in natural habitats. Sex-specific and diel patterns in metabolic rate were quantified. Metabolic rates did not differ between night and day and there was no significant difference in metabolic rate between males and females, exclusive of gravid females. Metabolic rates were lowest in salinity treatments of 2 and 8 at 29 °C, and highest in the salinity 2 treatment at 22 °C. Only temperature had a statistically significant, albeit unexpected, effect. This study shows that the metabolic response ofN. americanato temperature and salinity conditions is complex and plastic, and that metabolic rates can vary 3–4 fold within realistic summer temperature and salinity conditions. As environmental conditions continue to change, understanding metabolic response of mysids to realistic salinity and temperature conditions is necessary for understanding their distributions in temperate estuaries.
