Here, we present the first comprehensive dataset of functional traits for marine nematodes (MarNemaFunDiv). In this study, we propose 16 functional traits (life strategy, body shape, trophic group, oesophageal bulb, cuticle complexity, adhesive structures and ambulatory setae, head shape, amphid (shape and size), sensory structures (head and rest of the body), light sensing, male reproductive system (spicule, pre/postcloacal supplements and gubernaculum) and tail shape). Some of these traits were already used in marine ecology as functional categories (e.g. trophic groups, tail shapes, c-p classes) while others have never been considered before. These 16 traits were described and attributed to 86 nematode genera, representing the most abundant ones in shallow-water and deep-sea ecosystems. The matrix proposed in this study encompasses a comprehensive range of traits, enabling it to tackle a variety of ecological questions in the future.
在此，我们展示了首个关于海洋线虫功能性状的综合数据集（MarNemaFunDiv）。在本研究中，我们提出了16个功能性状（生活策略、身体形状、营养类群、食管球、角质层复杂度、附着结构和步足刚毛、头部形状、化感器（形状和大小）、感觉结构（头部和身体其他部位）、光感、雄性生殖系统（交合刺、泄殖腔前/后附属器和引带）以及尾部形状）。其中一些性状已在海洋生态学中作为功能类别使用（如营养类群、尾部形状、c-p类），而其他性状此前从未被考虑过。这16个性状被描述并归因于86个线虫属，这些属是浅水和深海生态系统中最丰富的属。本研究提出的矩阵涵盖了广泛的性状，使其能够在未来解决各种生态问题。
