在这里，我们在了解决定碳的分布和丰度的因素的背景下，对与流域规模的温度模式、浮游植物生物量、环流和其他环境特征相关的鳍马鞭藻丰度、人口统计、休眠、产卵和死亡率数据进行了新的泛大西洋汇编和分析。 finmarchicus 横跨其北大西洋栖息地。出现了许多主题：（1）东北大西洋浮游生物从南到北的运输与北大西洋西部从北到南的运输形成鲜明对比，这对于理解浮游生物的种群反应具有重要意义。 finmarchicusto 气候强迫，(2) 最年轻的桡足类阶段的补充发生在东部浮游植物盛开期间或之后，而在许多西部地点则发生在浮游植物盛开之后，补充时间差异长达 3.5 个月，(3) 挪威海南部的深盆和环流是 C. 的生产和越冬中心。 finmarchicus，周围水域赖以生存，而在拉布拉多/伊尔明格海，生产主要发生在边缘，因此深海盆地作为越冬种群的收集区和避难所，而不是生产中心，（4）北大西洋西部边缘海在维持高碳方面具有重要作用。附近沿海陆架上的finmarchicus丰富度，（5）北大西洋西部和东部平均温度和叶绿素浓度的差异反映在雌性体型和产蛋量的区域差异上，（6）产蛋率功能反应的区域差异可能反映了西部和东部种群之间的遗传差异，（7）邻近低纬度西北地区的深水区休眠持续时间普遍较短 大西洋陆架的生存率高于东部；（8）东部和西部陆架和盆地的特定阶段日死亡率存在差异，但从CI到CV的群体发育的生存轨迹相似；（9）在C. finmarchicusis 及其同源物被发现，C.冰川/或C.超博雷乌斯。该编译和分析为 C 种群模型的评估和参数化提供了新知识。 finmarchicus 及其对北大西洋气候变化的反应。讨论了建模方法的优点和缺点，包括基于生态位理论的统计方法和基于空间种群动态和生活史知识的动态方法，以及进一步研究的需要。
Here we present a new, pan-Atlantic compilation and analysis of data onCalanus finmarchicusabundance, demography, dormancy, egg production and mortality in relation to basin-scale patterns of temperature, phytoplankton biomass, circulation and other environmental characteristics in the context of understanding factors determining the distribution and abundance ofC. finmarchicusacross its North Atlantic habitat. A number of themes emerge: (1) the south-to-north transport of plankton in the northeast Atlantic contrasts with north-to-south transport in the western North Atlantic, which has implications for understanding population responses ofC. finmarchicusto climate forcing, (2) recruitment to the youngest copepodite stages occurs during or just after the phytoplankton bloom in the east whereas it occurs after the bloom at many western sites, with up to 3.5 months difference in recruitment timing, (3) the deep basin and gyre of the southern Norwegian Sea is the centre of production and overwintering ofC. finmarchicus,upon which the surrounding waters depend, whereas, in the Labrador/Irminger Seas production mainly occurs along the margins, such that the deep basins serve as collection areas and refugia for the overwintering populations, rather than as centres of production, (4) the western North Atlantic marginal seas have an important role in sustaining highC. finmarchicusabundance on the nearby coastal shelves, (5) differences in mean temperature and chlorophyll concentration between the western and eastern North Atlantic are reflected in regional differences in female body size and egg production, (6) regional differences in functional responses of egg production rate may reflect genetic differences between western and eastern populations, (7) dormancy duration is generally shorter in the deep waters adjacent to the lower latitude western North Atlantic shelves than in the east, (8) there are differences in stage-specific daily mortality rates between eastern and western shelves and basins, but the survival trajectories for cohort development from CI to CV are similar, and (9) early life stage survival is much lower in regions whereC. finmarchicusis found with its congeners,C. glacialisand/orC. hyperboreus. This compilation and analysis provides new knowledge for evaluation and parameterisation of population models ofC. finmarchicusand their responses to climate change in the North Atlantic. The strengths and weaknesses of modeling approaches, including a statistical approach based on ecological niche theory and a dynamical approach based on knowledge of spatial population dynamics and life history, are discussed, as well as needs for further research.
