Fig. 3 in Phylogeny and classification of Odonata using targeted genomics
Fig. 3. Current state of odonate phylogeny. Summary of the phylogenetic hypothesis for Odonata from Fig. 2. Support values for each node can be found in Fig. 2. Grey text highlights both the reinstated (Tatocnemididae stat. res., Rhipidolestidae stat. res.) and the proposed new families (Protolestidae fam. nov., Priscagrionidae fam. nov., Mesopodagrionidae fam. nov., Mesagrionidae fam. nov., and Amanipodagrionidae fam. nov.). Discussion of Grps. 1, 2, 3, and 4 is found in the Calopterygoidea section of the manuscript. Almost all major lineages are included and now have a hypothesized phylogenetic placement. The zygopteran genera Rimanella (Rimanellidae) and Sciotropis (Incertae Sedis group 8) were not included in this analysis.
Fig. 2 in Phylogeny and classification of Odonata using targeted genomics
Fig. 2. AHE topology. Results of the phylogenetic reconstruction of Odonata using loci captured from anchored hybridization enrichment. A) ML and Bayesian phylogenetic reconstruction of the Odonata using 478 loci. AZ in the right hand column represents the suborder Anisozygoptera. See "key to nodal support" for a visual guide to nodal support. Support values of 100 bootstrap and 1.0 posterior probability are not shown. Quartet sampling (QS) that shows full support (1/NA/1) is not shown at the node but all other QS is shown at each node along with a measure of taxon rogueness (QF score) at each branch tip. Bolded GF scores represent the lowest values across the topology. Newly established or reestablished families are shown in grey text. B) Arepresentation of the branch lengths are shown with all three suborders designated.
Occurrences and R code for: Dynamic distribution modeling of the Swamp Tigertail dragonfly Synthemis eustalacta (Odonata: Anisoptera: Synthemistidae) over a 20-year bushfire regime
<p>Intensity and severity of bushfires in Australia have increased over the past few decades due to climate change, threatening habitat loss for numerous species. Although the impact of bushfires on vertebrates is well-documented, the corresponding effects on insect taxa are rarely examined, although they are responsible for key ecosystem functions and services. Understanding the effects of bushfire seasons on insect distributions could elucidate long-term impacts and patterns of ecosystem recovery. Here, we investigated the effects of recent bushfires, land-cover change, and climatic variables on the distribution of a common and endemic dragonfly, the swamp tigertail (<em>Synthemis</em> <em>eustalacta</em> (Burmeister, 1839)), which inhabits forests that have recently undergone severe burning. We used a temporally dynamic species distribution modeling approach that incorporated 20 years of community-science data on dragonfly occurrence and predictors based on fire, land cover, and climate to make yearly predictions of suitability. We also compared this to an approach that combines multiple temporally static models that use annual data. We found that for both approaches, fire-specific variables had negligible importance for the models, while percent of tree and non-vegetative cover were the most important. We also found that the dynamic model outperformed the static ones when evaluated with cross-validation. Model predictions indicated temporal variation in area and spatial arrangement of suitable habitat but no patterns of habitat expansion, contraction, or shifting. These results highlight not only the efficacy of dynamic modeling to capture spatiotemporal variables, such as vegetation cover for an endemic insect species, but also provide a novel approach to mapping species distributions with sparse locality records.</p>
