TI  - Species-area relationships in the Andaman and Nicobar Islands emerge because 
      rarer species are disproportionately favored on larger islands.

AB  - The island species-area relationship (ISAR) describes how the number of species 
      increases with increasing size of an island (or island-like habitat), and is of 
      fundamental importance in island biogeography and conservation. Here, we use a 
      framework based on individual-based rarefaction to infer whether ISARs result 
      from passive sampling, or whether some processes are acting beyond sampling 
      (e.g., disproportionate effects and/or habitat heterogeneity). Using data on 
      total and relative abundances of four taxa (birds, butterflies, amphibians, and 
      reptiles) from multiple islands in the Andaman and Nicobar archipelago, we 
      examine how different metrics of biodiversity (total species richness, rarefied 
      species richness, and abundance-weighted effective numbers of species emphasizing 
      common species) vary with island area. Total species richness increased for all 
      taxa, as did rarefied species richness controlling for a given sampling effort. 
      This indicates that the ISAR did not result because of passive sampling, but that 
      instead, some species were disproportionately favored on larger islands. For 
      birds, frogs, and lizards, this disproportionate effect was only associated with 
      species that were rarer in the samples, but for butterflies, both more common and 
      rarer species were affected. Furthermore, for the two taxa for which we had 
      plot-level data (reptiles and amphibians), within-island beta-diversity did not 
      increase with island size, suggesting that within-island compositional effects 
      were unlikely to be driving these ISARs. Overall, our results indicate that the 
      ISARs of these taxa are most likely driven by disproportionate effects, that is, 
      where larger islands are important sources of biodiversity beyond a simple 
      sampling expectation, especially through their influence on rarer species, thus 
      emphasizing their role in the preservation and conservation of species.
