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

description: 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 (&lt;
 20,000 km2) or a mainland location (including islands &gt; 20,000km2)
 (0 = mainland, 1 = small island); V9: Threats - the different threats
 associated with each species; V10: Human development - the highest level
 of human development across the range of each species, measured using the
 Human Development Index (HDI); 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.

 Appendix G: Variables tested for their influence on rediscovery
 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 island (&lt; 20,000km2) or mainland location, including
 islands &gt; 20,000km2) (0 = mainland; 1 = small island); * V9: Threats
 (the different threat types associated with a species); * V10: Human
 development (the highest level of human development across the range of a
 species, measured using the Human Development Index (HDI)); * V11: Survey
 effort (the amount of effort invested in searching for a species: 1 = low,
 2 = medium, 3 = high, 4 = very high) (see Supporting Information (Table
 S1) for details on how this variable was calculated).
