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 km2) or a mainland location (including islands > 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.
