***<br>CAUTION: There have been minor corrections, additions (e.g. ranges of range type data) and updates to this dataset. Please find and download the correct and most recently updated file here: https://figshare.com/articles/Koutsidi_Moukas_Tzanatos_23_biological_traits_of_235_species/11347406 <br>***This file contains traits data for 235 Mediterranean nekton species. There are data on 23 traits; the data are presented in a continuous or a categorical form (in the latter case, for each trait 2-6 trait categories/modalities exist and each species can only belong to one modality per trait). The Excel file has 6 worksheets: (1) <b>Continuous_traits_205_sp</b>: This worksheet contains information on the continuous traits (longevity, age-at-maturity, fecundity, maximum length, trophic level, optimal depth, optimal temperature). For traits of the range type (e.g. optimal depth) the mean value are provided. Only the species with complete information (205 species) on continuous traits are presented. (2) <b>Categorical_23_traits_205_sp</b>: This worksheet is a presence/absence (1/0) matrix of 205 species by 81 traits categories (or modalities). Only the species with complete information (205 species) on all 23 traits are presented. (3) <b>Continuous_traits_235_sp</b>: This worksheet contains information on the continuous traits (longevity, age-at-maturity, fecundity, maximum length, trophic level, optimal depth, optimal temperature). For traits of the range type (e.g. optimal depth) the mean value are provided. All species, even with incomplete information on all continuous traits are presented. (4) <b>Categorical_23_traits_235_sp</b>: This worksheet is a presence/absence (1/0) matrix of 235 species by 81 traits categories (or modalities). All species, even with incomplete information on all 23 traits are presented. (5) <b>reference_codes_per_trait</b>: This worksheet is a matrix of the 235 species by 21 traits with one or more numbers representing a reference from which the information to fill in the trait information (shown in the previous worksheets) was taken. (6) <b>reference_list</b>: This worksheet is a list of reference numbers and the corresponding full references.

本数据集涵盖235种地中海自游生物（nekton），共包含23项功能性状数据，数据分为连续型与分类变量两种形式：对于分类变量，每项性状包含2至6个性状类别（模态），且每个物种仅能归属至每个性状的一个类别中。

该Excel文件包含6个工作表：
1. **Continuous_traits_205_sp**：本工作表包含7项连续型性状数据，分别为寿命、性成熟年龄、繁殖力、最大体长、营养级、最适水深及最适水温。对于区间型性状（如最适水深），本文件提供其均值。本工作表仅收录在连续型性状上具有完整信息的205个物种。
2. **Categorical_23_traits_205_sp**：本工作表为205个物种与81个性状类别（模态）对应的1/0（存在/缺失）矩阵。本工作表仅收录在全部23项性状上均具有完整信息的205个物种。
3. **Continuous_traits_235_sp**：本工作表包含7项连续型性状数据，分别为寿命、性成熟年龄、繁殖力、最大体长、营养级、最适水深及最适水温。对于区间型性状（如最适水深），本文件提供其均值。本工作表收录全部235个物种，即便其在连续型性状上存在信息缺失。
4. **Categorical_23_traits_235_sp**：本工作表为235个物种与81个性状类别（模态）对应的1/0（存在/缺失）矩阵。本工作表收录全部235个物种，即便其在全部23项性状上存在信息缺失。
5. **reference_codes_per_trait**：本工作表为235个物种与21项性状对应的矩阵，矩阵内的一个或多个数字代表该性状数据的参考文献编号，对应前文各工作表中收录的性状信息来源。
6. **reference_list**：本工作表为参考文献编号与完整参考文献内容的对应列表。
