Functional traits of benthic marine invertebrates associated with honeycomb worm reefs in Europe

reef-building species are recognized as having an important ecological role and as generally enhancing the diversity of benthic organisms in marine habitats. however, although these ecosystem engineers have a facilitating role for some species, they may exclude or compete with others. the honeycomb worm sabellaria alveolata (linnaeus, 1767) is an important foundation species, commonly found from northwest ireland to northern mauritania (curd et al., 2020), whose reef structures increase the physical complexity of the marine benthos, supporting high levels of biodiversity. local patterns and regional differences in taxonomic and functional diversity were examined in honeycomb worm reefs from ten sites along the northeastern atlantic to explore variation in diversity across biogeographic regions and the potential effects of environmental drivers. to characterize the functional diversity at each site, a biological trait analysis (bta) was conducted (statzner et al., 1994).here we present the functional trait database used for the benthic macrofauna found to live in association with honeycomb worm reefs. eight biological traits (divided into 32 modalities) were selected (table 1), providing information linked to the ecological functions performed by the associated macrofauna. the selected traits provide information on: (i) resource use and availability (by the trophic group of species, e.g. thrush et al. 2006); (ii) secondary production and the amount of energy and organic matter (om) produced based on the life cycle of the organisms (including longevity, maximum size and mode of reproduction, e.g. (cusson and bourget, 2005; thrush et al., 2006) and; (iii) the behavior of the species in general [i.e. how these species occupy the environment and contribute to biogeochemical fluxes through habitat, movement, and bioturbation activity at different bathymetric levels, e.g. (solan et al., 2004; thrush et al., 2006; queirós et al., 2013). species were scored for each trait modality based on their affinity using a fuzzy coding approach (chevenet et al., 1994), where multiple modalities can be attributed to a species if appropriate, and allowed for the incorporation of intraspecific variability in trait expression. the information concerning polychaetes was derived primarily from fauchald et al (1979) and jumars et al (2015). information on other taxonomic groups was obtained either from databases of biological traits (www.marlin.ac.uk/biotic) or publications (naylor, 1972; king, 1974; caine, 1977; lincoln, 1979; holdich and jones, 1983; smaldon et al., 1993; ingle, 1996; san martín, 2003; southward, 2008; gil, 2011; leblanc et al., 2011; rumbold et al., 2012; san martín and worsfold, 2015; jones et al., 2018).map indicating the locations of the 10 study sites in the uk, france and portugal within the four biogeographic provinces defined by dinter (2001). (all sites were sampled in 8 different stations, except for uk4 where 5 stations were sampled).

珊瑚建造物种因其重要的生态功能而被认知，通常能够增强海洋栖息地中底栖生物的多样性。然而，尽管这些生态系统工程师对于某些物种具有促进作用，它们可能排斥或与其他物种竞争。蜂巢虫 Sabellaria alveolata（Linnaeus，1767）是一种重要的基石物种，广泛分布于从西北爱尔兰至北部毛里塔尼亚（Curd 等人，2020年），其珊瑚结构增加了海洋底栖环境的物理复杂性，从而支持了高水平的生物多样性。本研究对东北大西洋十个地点的蜂巢虫珊瑚礁中的分类学和功能多样性进行了地方性模式和区域性差异的考察，以探究生物地理区域间的多样性变化以及环境驱动因素的可能影响。为了表征每个地点的功能多样性，进行了生物特性分析（Statzner 等人，1994年）。在此，我们展示了用于与蜂巢虫珊瑚礁共生的底栖大型无脊椎动物的功能特性数据库。选定了八个生物特性（分为32种模态），提供了与相关大型无脊椎动物所执行的生态功能相关的信息。所选特性提供的信息包括：（i）资源利用和可用性（通过物种的摄食群，例如 Thrush 等人，2006年）；（ii）次级生产和基于生物体生命周期（包括寿命、最大体型和繁殖方式，例如 Cusson 和 Bourget，2005年；Thrush 等人，2006年）产生的能量和有机物（OM）的数量；（iii）物种的一般行为[即这些物种如何占据环境并通过栖息地、运动和在不同水深层级的生物扰动活动参与生物地球化学通量的贡献，例如 Solan 等人，2004年；Thrush 等人，2006年；Queirós 等人，2013年]。根据物种的亲和度，对每个特性模态进行了评分，采用模糊编码方法（Chevenet 等人，1994年），若适当，一种物种可被赋予多个模态，并允许将特性表达的种内变异性纳入其中。关于多毛类的信息主要来源于 Fauchald 等人（1979年）和 Jumars 等人（2015年）。其他分类群的信息则来源于生物特性数据库（www.marlin.ac.uk/biotic）或出版物（Naylor，1972年；King，1974年；Caine，1977年；Lincoln，1979年；Holdich 和 Jones，1983年；Smaldon 等人，1993年；Ingle，1996年；San Martín，2003年；Southward，2008年；Gil，2011年；Leblanc 等人，2011年；Rumbold 等人，2012年；San Martín 和 Worsfold，2015年；Jones 等人，2018年）。地图显示了位于英国、法国和葡萄牙的十个研究地点在 Dinter（2001年）定义的四个生物地理省内的位置。（所有地点均在8个不同的站位进行采样，除了 UK4，该地点采样了5个站位。）
