Idespread flavonoids), terpenoids (e.g., iridoid glycosides, triterpenoid saponins), or ranunculin (characteristic of your Ranunculaceae). Following the distinct host plant(s) of each sawfly species, host toxicity was then coded as `never’ (code `0′), in some cases (`1′), or `always’ (`2′), depending on the feasible occurrence of toxins in the diet plan. As an example, the code was `0′ for any specialist sawfly species feeding on a non-toxic plant genus, `1′ for a generalist feeding on both toxic and non-toxic hosts, and `2′ to get a sawfly species only feeding on a toxic plant, or feeding on various plant taxa which are all toxic.Ten ecological traits linked to the behavior, morphology and chemical ecology from the sawfly larvae have been coded as far as these traits are involved in defense (see Figure 3). The data had been extracted from regular performs on sawflies (e.g., [48,55,64,73] and literature therein), a precise operate on quick bleeding [40], at the same time as unpublished observations and sources. For traits altering in the course of successive larval stages, the final stage preceding the (frequently non-feeding) eonymph was viewed as.Correlation analysesThe existence of phylogenetic correlations amongst several ecological and defensive traits was evaluated by Bayesian stochastic character mapping [74,75] as implemented in SIMMAP v. 1.five.two [76]. For these analyses, we chosen 10 out with the 66 character-pair comparisons which can be possible among the 12 focal traits listed in Table 1. Most correlations to become performed were selected determined by previously proposed hypotheses (see [39,40,47] and Table 2). Stateby-state associations in between characters have been evaluated determined by the dij statistic, which measures co-occurrence of states i and j across branches in relation for the expectation below independent evolution [75].
