Koutsidi_Moukas_Tzanatos_21_traits_by_235_species.xls

This file contains traits data for 235 Mediterranean fisheries resource species. There are data on 21 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 5 worksheets: (1) <b>continuous_traits_235_species</b>: This worksheet contains information on the continuous traits (longevity, age-at-maturity, fecundity, maximum length, trophic level, depth, optimal temperature). For traits of the range type (e.g. depth) minimum and maximum values as well as the mean value are provided. (2) <b>complete_21_traits_205_species</b>: This worksheet is a presence/absence (1/0) matrix of 205 species by 75 traits categories (or modalities). Only the species with complete information (205 species) on all 21 traits are presented. (3) <b>incomplete_21_traits_235_species</b>: This worksheet is a presence/absence (1/0) matrix of 205 species by 75 traits categories (or modalities). All species, even with incomplete information (235 species) on all 21 traits are presented. (4) <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. (5) <b>reference_list</b>: This worksheet is a list of reference numbers and the corresponding full references.

本数据集收录了235种地中海渔业资源物种的性状数据，共涵盖21项性状指标，数据形式分为连续型（continuous）与分类型（categorical）两类；针对分类型数据，每项性状存在2至6个分类模态（trait modality），且每个物种仅能归属至单一分类模态下。该Excel文件包含5个工作表，具体如下：1. **continuous_traits_235_species**：该工作表收录了连续型性状的相关信息，包括寿命、性成熟年龄、繁殖力、最大体长、营养级、栖息深度、适宜温度。针对范围类性状（如栖息深度），将同时提供其最小值、最大值与均值。2. **complete_21_traits_205_species**：该工作表为205个物种与75个性状分类（模态）的存在/缺失（1/0）矩阵（presence/absence matrix），仅收录了21项性状信息均完整的205个物种。3. **incomplete_21_traits_235_species**：该工作表为205个物种与75个性状分类（模态）的存在/缺失（1/0）矩阵，收录了全部235个物种——即便其21项性状的信息存在缺失。4. **reference_codes_per_trait**：该工作表为235个物种与21项性状的矩阵，单元格内的一个或多个编号代表填充前述工作表中性状信息的参考文献来源。5. **reference_list**：该工作表为参考文献编号与对应完整参考文献的列表。
