Squamate phylogeny incorporated in PGLS analyses

Phylogenetic relationships used to obtain the supertree were compiled from the literature

Relationships between parameters of the performance curve

After accounting for phylogenetic relationships across species, the critical thermal minimum was not related to (a) the critical thermal maximum (CTmax) (PGLS, n = 111, P > 0.05) or to (b) the preferred body temperature (Tp) (PGLS, n = 97, P > 0.05). By contrast, (c) CTmax and Tp were strongly related (PGLS, n = 133, P < 0.05)

Squamate thermal data compiled from the literature. Tp is the preferred body temperature, CTmax is the critical thermal maximum and CTmin is the critical thermal minimum

The relationship between the price of traded bird species in Taiwanese pet market and the percentage of a given colour found on the species, and colour diversity.

<p>The averaged coefficients (median estimates, [5^th, 95^th percentiles]) from univariate analysis on the relationship between the log-transformed price of bird species for sale in Taiwanese pet shops and the arcsine square root transformed percentage of a given colour found on the species, and colour diversity (in the first column), were calculated over 100 likely phylogenetic trees. Parameter Lambda (λ) indicates the strength of phylogenetic signal in the price of birds for sale in Taiwan.</p><p>*significant applying a Bonferroni correction for multiple tests; N = 217 in each case.</p><p>The relationship between the price of traded bird species in Taiwanese pet market and the percentage of a given colour found on the species, and colour diversity.</p

The relationship between log price and log abundance of alien and native species recorded in Taiwan.

<p>Red circles indicate the alien species and black triangles indicate the native species for sale in Taiwanese pet shops. The line indicates the best fit relationship between log price (in Taiwanese Dollars, or TWD) and log numbers irrespective of native or alien status (r² = 0.27, n = 217). Both transformations are natural logarithms.</p

Model coefficients in PGLS models for determinants of the price of birds in Taiwanese pet shops.

<p>Model coefficients (median estimates, [5^th, 95^th percentiles]) in PGLS models (ΔAIC from the best model is less than 4) for determinants of the price of birds in Taiwanese pet shops, were calculated over 100 randomly selected likely phylogenetic trees. Model ranks (top 3 rankings shown) are based on ΔAIC. Parameter Lambda (λ) indicates the strength of phylogenetic signal in the price of birds for sale in Taiwan for each likely model. IUCN status divided species by whether they are classed in the category of least concern.</p><p>Model coefficients in PGLS models for determinants of the price of birds in Taiwanese pet shops.</p
