We assessed the effect of seasonal variations on the biochemical composition and lipoperoxidation of an amphipod crustacean, Hyalella curvispina, which inhabits the coastal plain of the state of Rio Grande do Sul, and correlated this with information on the biology of the species. The animals were collected monthly from September 2003 to August 2005, in Gentil Lagoon, Tramandaí, Rio Grande do Sul, Brazil. Glycogen levels, total proteins, total lipids, triglycerides, and lipoperoxidation were measured for each sex separately. The results suggest that these animals have seasonal storage and degradation of the energy substrates investigated. During summer, glycogen, total lipids, and triglycerides were stored, and were utilized especially during autumn and winter. Proteins were utilized differently in males and females. Females stored proteins especially in spring and used them in summer; whereas males stored proteins especially in spring and used them in winter. The levels of lipoperoxidation during the year differed between females and males. These variations may be related to biotic factors (e.g., reproduction period and others) and to abiotic factors (e.g., water temperature, salinity and others).
我们评估了季节变化对一种生活在巴西南里奥格兰德州沿海平原的双甲目甲壳动物弯刺长臂虾（Hyalella curvispina）生化组成和脂质过氧化的影响，并将其与该物种的生物学信息相关联。2003年9月至2005年8月期间，每月在巴西南里奥格兰德州特拉曼代伊的金泰尔泻湖采集这些动物。分别测量了每种性别的糖原水平、总蛋白、总脂质、甘油三酯和脂质过氧化水平。结果表明，这些动物对所研究的能量底物有季节性的储存和降解。在夏季，糖原、总脂质和甘油三酯被储存起来，尤其在秋季和冬季被利用。蛋白质在雄性和雌性中的利用方式不同。雌性尤其在春季储存蛋白质并在夏季使用；而雄性尤其在春季储存蛋白质并在冬季使用。一年中脂质过氧化水平在雌性和雄性之间存在差异。这些变化可能与生物因素（如繁殖期等）和非生物因素（如水温、盐度等）有关。
