摘要

北极岛屿提供了美国东北大陆架气候变化的长期记录,与寒暖气候期同步发生了多次跨大陆架的海侵和退行。在广泛的地理和时间范围内,岛屿拟南芥在死亡组合中的可用性使该物种非常适合通过响应变化的水条件的生长率的相关性来记录大西洋中部气候变化的时空影响。本研究的重点是比较在Delmarva半岛(Delmarva)近海获得的生活在全新世气候最适宜期以来寒冷时期的亚化石海洋quahogs与生活在新泽西州近海、长岛近海和乔治海岸的A. islandica的区域生长情况。这些种群表现出不同的生长速度,来自Delmarva死亡组合的亚化石个体,代表了全新世之前的寒冷时期,其生长速度大于或等于现存个体的生长速度。此外,生活在1740年至1940年的Delmarva岛古猿亚化石的生长速度比生活在今天的同时期个体要快。Delmarva附近的A. islandica的较高生长速度表明,在全新世气候最佳期后的寒冷时期,条件支持了接近最大生长,可能是由于比今天居住的水域浅的水域增加了食物供应。与许多双壳类动物不同,随着底部水温变暖,岛屿甲壳动物的范围缩小的证据首先出现在幼鱼数量丰富的时候,这表明在种群消亡之前很久就停止了补充:该物种的范围缩小是一个100多年的过程,由最老和最大的个体的存活率决定。这项研究是有史以来最大的岛屿拟南猿的时空生长比较,也是首次记录该物种的近岸范围随着温度上升而退化的过程。

Temporal and spatial comparisons of ocean quahog (Arctica islandica) growth and lifespan on the mid-Atlantic continental shelf during inshore transgressions of their range from the Neoglacial through the twentieth century

Arctica islandica provide long-term records of climate change on the U.S. northeast continental shelf transgressing and regressing across the shelf numerous times synchronously with cold and warm climatic periods. The availability of A. islandica in the death assemblage over a wide geographic and temporal range makes this species well suited for documenting both spatial and temporal influences of climate change in the Mid-Atlantic through the correlation of growth rates in response to changing water conditions. This study focuses on comparing regional growth of subfossil ocean quahogs obtained offshore of the Delmarva Peninsula (Delmarva), and living during the cold periods since the Holocene Climate Optimum, with living A. islandica from offshore New Jersey, offshore Long Island, and Georges Bank. These populations exhibited different growth rates, with subfossil individuals from Delmarva death assemblages, representing previous Holocene cold periods, having growth rates as greater than or equal the growth rates of living individuals. Moreover, the growth rates for subfossil A. islandica from Delmarva that were alive from 1740 to 1940 were more rapid than contemporaneous individuals of the same age alive today. Higher growth rates for A. islandica from off Delmarva suggest that conditions supported near maximum growth during the cold periods after the Holocene Climate Optimum, possibly due to increased food supply in water shallower than that inhabited today. Unlike many bivalves, evidence for range recession of A. islandica as bottom water temperatures warm is found first in juvenile abundance, suggesting that recruitment ceases long before the population's demise: range recession in this species is a 100+ year process determined by the survivorship of the oldest and largest individuals. This study is the largest spatial and temporal growth comparison of A. islandica ever recorded and the first record of the process by which this species' inshore range regresses as temperatures rise.

期刊介绍: Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
