Where's my dinner? Do Arctic benthic communities show preferential food uptake?

项目概述该项目将调查巴伦支海纵向断面沿着的大型底栖动物群落，并在不同的季节，试图确定动物群是否优先以冰藻为食，而不是以植物为食。巴伦支海动物群落变化的文献综述，确定动物群，以便确定底栖生物群落的组成、物种和功能多样性。第2年：在Akvaplan-niva/特罗姆瑟大学协助鉴定身份的时间。对大型底栖动物中发现的高度分支的类异戊二烯进行调查。确定分子（脂质）和同位素（15 N和13 C）在预定位置代表不同大小类别的选定动物的比率，以确定营养位置，监督团队Bhavani Narayanaswamy博士（SAMS）Kim Last博士（SAMS）大卫麦基博士（斯特拉斯克莱德大学）Paul Renaud博士（Akvaplan-niva）Bodil Bluhm教授（特罗姆瑟大学）

Project OverviewThe project will investigate the benthic macrofaunal communities along a Longitudinal transect in the Barents Sea, and over different seasons to try and determine whether the fauna preferentially feed on ice algae as opposed to phytoplanktonThe project Year 1: Literature review on the changing faunal community in the Barents Sea, and more widely in the Arctic and the impact of a changing climate and food resources.To identify the fauna to allow for determining the composition and, species and functional diversity of the benthic communities Year 2: Time spent at Akvaplan-niva/University of Tromso to aid with identification. Investigations of the highly branched isoprenoids found in the larger benthic fauna.Year 3: To determine the molecular (lipids) and isotopic (15N and 13C) ratios of selected fauna representing the different size classes at pre-determined locations in order to identify trophic position, relationships and resource partitioning.Supervisory TeamDr Bhavani Narayanaswamy (SAMS)Dr Kim Last (SAMS)Dr David Mckee (University of Strathclyde)Dr Paul Renaud (Akvaplan-niva)Professor Bodil Bluhm (University of Tromso)
