Specific studies are designed to examine aspects of life history events in one of the GLOBEC target species, the copepod Calanus finmarchicus. Individual vector models will be developed for life history events, population growth, and advective transport for C. finmarchicus in the Gulf of Maine and over Georges Bank. Mandibular morphology and gonad development will be used to quantify the proportions of individuals that decide to enter diapause or to mature. Tooth formation will also serve to indicate when stocks are ending or continuing diapause in autumn and winter months. Diapause/maturation decisions and sex change frequency will be examined by analyses of DNA fragments. These studies will document interannual environmental factors that influence sex determination. Wax storage rates will be estimated by video microscopy and Iatroscan chromatography. Work done by this project will constitute the western Atlantic component of a international program titled TransAtlantic Studies of Calanus finmarchicus. Parallel studies on life history decisions, sex change frequency, and lipid storage will be conducted off Norway (two latitudes), Iceland, northern Scotland and in the North Sea. +- ±- + _ Ûª▓ ÑOh ª' +'ª▒0 h + Õ $ H l + ¢ ╗ D R:\WWUSER\TEMPLATE\NORMAL.DOT Sheryl Miller @ -+Y+ª) @ -+Y+ª) @ Ù░E S u m m a r y I n f o r m a t i o n ( ++++++++++++ ` + ++++++++++++ ++++++++++++ ++++++++++++ ▀ @ ªí- Microsoft Word 6.0 9 Õªe =- e O ª O f f f f f f p f 1 z z z z z z z z & ( ( ( F = = ÷ = T ' ` z z z z z z z z z z z z z z & P X z & z - z 0"

特定的研究旨在检查全球目标物种之一的生活历史事件的各个方面。将为缅因州海湾和乔治银行（Georges Bank）的生命历史事件，人口增长和高级运输开发各个向量模型。下颌形态和性腺发育将用于量化决定进入滞育或成熟的个体的比例。形成牙齿还将表明秋季和冬季何时结束或继续滞留。二骨/成熟决策和性别变化频率将通过对DNA片段的分析来检查。这些研究将记录影响确定性确定的年际环境因素。蜡存储速率将通过视频显微镜和杂草色色谱法估算。该项目所做的工作将构成一项名为“ Calanus Finmarchicus的跨大西洋研究”的国际计划的西大西洋组成部分。关于生活历史决定，性别变化频率和脂质存储的平行研究将在挪威（两个纬度），冰岛，苏格兰北部和北海进行。 +- ±- + _ Ûª▓ ÑOh ª' +'ª▒0 h + Õ $ H l + ¢ ╗ D R:\WWUSER\TEMPLATE\NORMAL.DOT Sheryl Miller @ -+Y+ª) @ -+Y+ª) @ Ù░E S u m a r y I n f o r m a t i o n ( ++++++ ` + +++++++ ▀ @ ªí-microsoft Word 6.0 9ªe= -e o o o f f f f f f f f f f f p f 1 z z z z z z z z z z z z z z z＆（（（（（（f = =÷=÷= T'``
