Input files

We provide here the files used as inputs to simulate neutral dynamics on spatially structured and unstructured archipelagos. Details on the structure of these inputs are given as comments in the algorithms, and simple exemples are provided with the Codes of the models. This data include: the carrying capacities on islands/archipelagos (CarryingCapacities_...txt), the species abundance distributions of the mainland species (Distri_mainland...txt), the matrices of connectivity (Mcon_...txt), and the sampling frequencies on islands/archipelagos (SamplingFrequency...txt)

Codes of the spatially structured and unstructured neutral models

We provide here the algorithms used to model neutral dynamics on spatially-structured and unstructured archipelagos, as introduced in the main text and Supporting Information 3. These algorithms are coded in Java language, and their structure and use is explained in the file Readme.txt

Drepanotrema depressissimum microsatellite genotypes (GenAlEx)

Drepanotrema depressissimum microsatellite genotypes as GenAlEx format. For more information on sampling locations see the corresponding habitat characteristics data file

Aplexa marmorata microsatellite genotypes (Rmes)

Aplexa marmorata microsatellite genotypes as Rmes format. Rmes estimates unbiased selfing rates from population genetic data, for more information or to download the Rmes sofware see :http://www.cefe.cnrs.fr/en/genetique-et-ecologie-evolutive/patrice-david

Habitat characteristics (Drepanotrema depressissimum sites)

Habitat characteristics of the 32 sites where Drepanotrema depressissimum has been sampled for genetic analysis. "Lat" and "Long" are site latitude and longitude respectively (WGS84). "Year" is the sampling year. "Si", "V", "C", "St" and "G" are the five habitat characteristics used in the study (see the Materials and methods for more details). "SR", "SR_Pulmonates" and "SR_Caenogastropods" are long-term estimations of total species richness, Pulmonate species richness, and Caenogastropod species richness respectively

Habitat characteristics (Aplexa marmorata sites)

Habitat characteristics of the 43 sites where Aplexa marmorata has been sampled for genetic analysis. "Lat" and "Long" are site latitude and longitude respectively (WGS84). "Year" is the sampling year. "Si", "V", "C", "St" and "G" are the five habitat characteristics used in the study (see the materials and methods for more details). "SR", "SR_Pulmonates" and "SR_Caenogastropods" are long-term estimations of total species richness, Pulmonate species richness, and Caenogastropod species richness respectively
