What factors influence the rediscovery of lost tetrapod species? Appendix G: Variables tested for their influence on rediscovery

For the study associated with this dataset, we created a database of lost and rediscovered tetrapod species and identified patterns in their distribution and factors influencing rediscovery. This appendix provides a list of the lost and rediscovered species and all data used to calculate 11 variables (V):

V1: Taxonomic status - class, order, family, species name, common name;
V2: Countries / islands occupied by each species;
V3: The cumulative number of lost and rediscovered species - four columns, (i) last seen date, (ii) rediscovered date, (iii) for rediscovered species, the number of years lost, (iv) for lost species, the number of years lost;
V4: Time lost (the number of years each species has been lost for);
V5: Adult body mass (g) of each species;
V6: Habitat breadth - the number of broad habitat types occupied by each species;
V7: Habitat type - the broad habitat types occupied by each species;
V8: Small island / mainland - whether a species occupies a small island (< 20,000 ..., Please refer to the published paper associated with this dataset, which provides a detailed description of the data collection methods., , # What factors influence the rediscovery of lost tetrapod species?

Data associated with 11 variables tested for their influence on rediscovery.

## Description of the data and file structure

This Excel spreadsheet includes the data used to calculate 11 variables for each of 1280 species:

* V1: Taxonomic status (class, order, family, species name, common name)
* V2: Countries / islands of occupancy
* V3: The cumulative number of lost and rediscovered species from different classes within different decades (four columns: (i) last seen date, (ii) rediscovered date, (iii) the number of years lost for rediscovered species, (iv) the number of years lost for lost species);
* V4: Time lost (years);
* V5: Body mass (g);
* V6: Habitat breadth (the number of broad habitats occupied);
* V7: Habitat type (the types of broad habitats occupied);
* V8: Small island / mainland (whether the species occupied a small islan...

本数据集关联的研究中，我们构建了一个失踪后被重新发现的四足类（tetrapod）物种数据库，并梳理了其分布模式以及影响物种被重新发现的相关因素。本附录列出了所有失踪后被重新发现的物种，以及用于计算11个变量（V）的全部原始数据：
V1：分类学地位——包含纲、目、科、物种学名、通用俗名；
V2：各物种的分布国家/岛屿；
V3：不同类群、不同年代的失踪与重新发现物种累计统计——共四列：(i) 末次观测日期，(ii) 重新发现日期，(iii) 重新发现物种的失踪时长（年），(iv) 失踪物种的失踪时长（年）；
V4：失踪时长（单位：年）；
V5：各物种的成体体重（单位：克）；
V6：生境广度——各物种所占据的宽泛生境类型数量；
V7：生境类型——各物种所占据的宽泛生境类型；
V8：小型岛屿/大陆——物种是否栖息于面积小于20000[原文截断]的小型岛屿。
