Of fourCharacter coding and reconstruction of ancestral statesIn order to infer the evolutionary history of traits connected to niche use and defense within Tenthredinidae, we collected data on diet breadths, host-plant associations, and host features, also as on larval ecology, behavior, morphology, and chemically-based defensive methods inside the species included inside the phylogenetic trees. We then coded the information as unordered binary or multistate characters, and reconstructed ancestral states by singlerate (Mk1) maximum likelihood (ML) optimization in Mesquite v. two.75 [63].

Host plants have been compiled from literature sources [55,64] and each sawfly was coded for its eating plan breadth (Figure three). Inside the case of species for which dependable hostplant records had been missing, eating plan breadth was coded as unknown, unless revealed by additional laboratory testing with larvae in the exact same population.To evaluate the toxicity of plants on which sawflies feed, every plant genus (and species, as far as you possibly can) was related with all the occurrence of toxins, by referring to regular works on the chemistry of plants [65-70] and to smaller sized andor more recent functions (e.g., [45]). A plant taxon was deemed toxic when the leaves contain secondary metabolites from one particular or more of your following chemical classes: alkaloids (which includes steroid alkaloids and steroidBoevet al.

The BEAST MCC tree is depending on evaluation of Dataset two, which contains all sequenced tenthredinids as well as representatives from three non-blasticotomid families in Tenthredinoidea. Posterior probabilities ( ) resulting from analyses in BEAST and MrBayes are given above and under branches, respectively (clades not present in the MrBayes tree are indicated by hyphens). Grey shaded bars show the 95 highest posterior density intervals for relative node ages for nodes with posterior probabilities exceeding 50 . Branch colors denote host plant classes in the sawfly species (see legend) and ancestral reconstructions according to maximum-likelihood optimization across 1,000 post-burnin trees (see Added file 4A).

All these compounds, except steroid saponins, have in common the inclusion of one particular or extra nitrogen atoms. Nitrogencontaining secondary metabolites show acute toxicity andor powerful feeding deterrence towards vertebrates andor invertebrates, and they are by far the most popular defensive chemical substances of plants [65,68-70,72]. A plant taxon was thought of non-toxic if it only contains secondary metabolites that do not include nitrogen, for example phenolics (e.g., coumarins, phenolic glycosides, along with the w.
