Stuart_etal_dataframes.RData

This R workspace image contains two dataframes, one for anoles and one for terraranans. Each data frame contains pairwise environmental dissimilarity and species turnover values for island and mainland sub regions. The columns are: | geo_dist: geographic distance between sampling areas | climelev.pc.dist: environmental distance between sampling areas from a pca on environmental variables and elevation | log.area.diff: the difference in log area between sampling areas | sor: Sorensen's index of species turnover | jac: jaccard's index | comp.type: Identifies measures as mainland-mainland (m.m), mainland-island (i.m), or island-island (i.i) | comp.nums: identifies the corresponding sampling areas, which are mapped in the accompanying ArcGIS grids in the Stuart_etal_sample_areas.zip fil

Colors exhibited by each pattern.

<p>Numbers in the right-hand column refer to the number of morphs exhibiting the color in the indicated pattern, yielding an indication of color diversity within each pattern.</p

Stuart_etal_sample_areas

Stuart_etal_sample_areas.zip | This compressed folder contains two ArcGIS grids: ter_m_i_samp (Terraranans) and an_m_i_samp (anoles). Each grid shows the mainland range of the relevant clade (values of 1.0), mainland sampled areas (50xxx) and islands included in the analysis(60xxx

Data used to test the Ecomorph Convergence hypothesis.

<p>Abbreviations as follows: Community: C = Cuba, H = Hispaniola, J = Jamaica, and PR = Puerto Rico; Ecomorph:, CG = crown-giant, GB = grass-bush, TC = trunk-crown, TG = trunk-ground, TR = trunk, TW = twig; and U = unique. Dewlap size data comes from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0000274#pone.0000274-Losos1" target="_blank">[16]</a>. Species polymorphic for pattern (e.g., basal/solid/marginal) are indicated in the next to last column and the corresponding colors exhibited by each pattern for each species is indicated in the far right column. Polymorphism in color is similarly indicated (e.g., may have a solid pattern only but may vary in coloration, red/yellow/orange).</p

Figure 4

<p>A histogram depicting the frequency of dewlap pattern and color combinations. *Data were weighted by the proportion of polymorphism exhibited by each species. For example, if a species exhibited four dewlap morphs and one was a solid yellow dewlap, a score of 0.25 was recorded for the solid yellow dewlap category.</p

Data used to test the Species Recognition hypothesis.

<p>Not included in this analysis due to missing data were <i>A. cybotes</i> (Hispaniola), <i>and A. ricordii</i> (Hispaniola). Patterns and colors are as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0000274#pone-0000274-t003" target="_blank">Table 3</a>.</p

Figure 3

<p>Dewlap patterns mapped on to a phylogeny for <i>Anolis</i> species. Patterns are indicated in color on the phylogeny (color legend upper left). Polymorphic species are those that exhibited two or more pattern morphs (see text for how this was handled analytically). Patterns are defined in the text. This tree includes all of the species used in the tests for phylogenetic signal of dewlap characters. The tree is modified from Nicholson et al.'s <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0000274#pone.0000274-Nicholson1" target="_blank">[20]</a> anole tree but has been pruned of taxa for which dewlap information was lacking. Analyses were based on an ultrametric version of this tree, but is reproduced here in cladogram form for enhanced viewing of dewlap pattern information.</p

Figure 2

<p>Dewlap patterns categorized by this study. Six patterns were observed among Caribbean <i>Anolis</i> species. While five of the patterns (Solid, Marginal, Basal, Striped, and Spotted) were observed with some frequency, four additional morphs were observed so rarely that they were grouped together within a sixth category entitled Divided.</p
