ESM Table 2 Model selection using Akaike's information Criteria (AIC) for (a) leaf miners and (b) plant gallers using four plant traits and four environmental variables across 46 Acacia species. Variables include 1- mean maximum temperature, 2 – mean minimum temperature, 3 – mean annual rainfall, 4 – latitude, 5 – C:N ratio, 6 - % Phosphorus, 7 – foliage thickness, and 8 – SLA.
