What factors influence the rediscovery of lost tetrapod species? Appendix G: Variables tested for their influence on rediscovery
<p>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):</p> <ul> <li>V1: Taxonomic status - class, order, family, species name, common name;</li> <li>V2: Countries / islands occupied by each species;</li> <li>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;</li> <li>V4: Time lost (the number of years each species has been lost for);</li> <li>V5: Adult body mass (g) of each species;</li> <li>V6: Habitat breadth - the number of broad habitat types occupied by each species;</li> <li>V7: Habitat type - the broad habitat types occupied by each species;</li> <li>V8: Small island / mainland - whether a species occupies a small island (< 20,000 km<sup>2</sup>) or a mainland location (including islands > 20,000km<sup>2</sup>) (0 = mainland, 1 = small island);</li> <li>V9: Threats - the different threats associated with each species;</li> <li>V10: Human development - the highest level of human development across the range of each species, measured using the Human Development Index (HDI);</li> <li>V11: Survey effort - the level of effort invested in searching for each species (1 = low, 2 = medium, 3 = high, 4 = very high). See Supporting Information (Table S1) for the methods used to calculate this variable.</li> </ul>
What factors influence the rediscovery of lost tetrapod species? Appendix E: Lost and rediscovered species
<p>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 tetrapod species used in the analysis. It includes data on:</p> <ul> <li>taxonomy (class, order, family, species, common name, and whether the species is a subspecies);</li> <li>location (continent, country, region);</li> <li>each species threat status (as published on the IUCN Red List of Threatened Species: <a href="https://www.iucnredlist.org/">https://www.iucnredlist.org/</a>).</li> </ul> <p>The appendix also indicates:</p> <ul> <li>whether each species was included in another list of lost tetrapod species published by the organisation Re:wild (<a href="https://www.rewild.org/">https://www.rewild.org/</a>);</li> <li>whether each species was used to construct the phylogenetic trees used for analysis.</li> </ul>
What factors influence the rediscovery of lost tetrapod species? Appendix F: Excluded species
<p>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. Our lost species list included many of the species on another published list of lost species compiled by Re:wild (<a href="https://www.rewild.org/)">https://www.rewild.org/)</a> in collaboration with the International Union for Conservation of Nature (IUCN) (<a href="https://www.iucn.org/">https://www.iucn.org/</a>). However, we did not include some of the species included on the Re:wild/IUCN list. This appendix provides a list of those species. It includes the following information for each species:</p> <ul> <li> <p>taxonomy - class, order, scientific name, common name;</p> </li> <li> <p>threat status (as published on the IUCN Red List of Threatened Species);</p> </li> <li> <p>location - continent / island, range / country.</p> </li> </ul>
