Climate gradients, and patterns of biodiversity and biotic homogenization in urban residential yards

Fig 6. Relative abundance of typical snail species comprising 90% of the Bray-Curtis similarity within each town, based on SIMPER analysis. Grid pattern of pie diagrams reflects the grid pattern of towns. Snail families are color- coded: greens = Zonitidae; blues = Polygyridae; reds = Vertiginidae; all other families (other colors) are monospecific within the typical taxa for each town. White areas are the pooled relative abundance of all other snail species. Crossed circles indicate non-native species. Black lines connecting pie diagrams indicate non-significant differences in snail composition between town pairs. https://doi.org/10.1371/journal.pone.0234830.g006 PLOS ONE Diversity patterns of yard-dwelling snails across climate gradients PLOS ONE | https://doi.org/10.1371/journal.pone.0234830 August 28, 2020 10 / 18
