“…Shear (1980) erected the family Pettalidae based on a non-numerical cladistic analysis of the suborder Cyphophthalmi. In two recent cladistic analyses of morphological data by Giribet and Boyer (2002) and Giribet (2003a), Pettalidae was found to be monophyletic, and analyses of molecular data for Cyphophthalmi including preliminary subsets of the current data for pettalids also retrieved the family as a clade (Giribet and Boyer, 2002;Boyer et al, 2005;Schwendinger and Giribet, 2005). Strongly supported and stable monophyly of Pettalidae is further corroborated in this study.…”

“…Total DNA was extracted from whole animals using a DNeasy Ò Tissue Kit (Qiagen, Valencia, CA), either by crushing the individual or one appendage in the lysis buffer or by incubating an intact animal or appendage in lysis buffer overnight, then removing the specimen before proceeding with the rest of the manufacturer's extraction protocol, as described by Boyer et al (2005).…”

The phylogeny of the temperate Gondwanan harvestman family Pettalidae is investigated by means of a new morphological matrix of 45 characters, and DNA sequence data from five markers, including two nuclear ribosomal genes (18S rRNA and 28S rRNA), one nuclear protein coding gene (histone H3), and two mitochondrial genes-one protein coding (cytochrome c oxidase subunit I) and one ribosomal (16S rRNA). Phylogenetic analyses using an array of homology schemes (dynamic and static), criteria (parsimony and maximum likelihood), and sampling strategies (optimal trees versus Bayesian phylogenetics) all agree on the monophyly of Pettalidae as well as several of its subclades, each of which is restricted to a modern landmass. While most genera as traditionally defined are monophyletic, Rakaia and Neopurcellia, distributed across Queensland (Australia) and New Zealand, are not. Instead, the species from Queensland, previously described under three genera, constitute a well-supported clade, suggesting that in this case biogeography prevails over traditional taxonomy. A taxonomic emendation of the genera from Queensland and New Zealand is presented, and the new genus Aoraki is erected to include the species of the New Zealand denticulata group. A biogeographical hypothesis of the relationships of the former temperate Gondwana landmasses (with the exception of Madagascar) is presented, although ambiguity in the deep nodes of the pettalid tree renders such inference provisional.

Phylogeny of Branchiopoda (Crustacea) based on a combined analysis of morphological data and six molecular loci

The phylogenetic relationships of branchiopod crustaceans have been in the focus of a number of recent morphological and molecular systematic studies. Although agreeing in some respects, major differences remain. We analyzed molecular sequences and morphological characters for 43 branchiopods and two outgroups. The branchiopod terminals comprise all eight ''orders''. The molecular data include six loci: two nuclear ribosomal genes (18S rRNA, 28S rRNA), two mitochondrial ribosomal genes (12S rRNA, 16S rRNA), one nuclear protein coding gene (elongation factor 1a), and one mitochondrial protein coding gene (cytochrome c oxidase subunit I). A total of 65 morphological characters were analyzed dealing with different aspects of branchiopod morphology, including internal anatomy and larval characters. The morphological analysis resulted in a monophyletic Phyllopoda, with Notostraca as the sister group to the remaining taxa supporting the Diplostraca concept (''Conchostraca'' + Cladocera). ''Conchostraca'' is not supported but Cyclestheria hislopi is the sister group to Cladocera (constituting together Cladoceromorpha) and Spinicaudata is closer to Cladoceromorpha than to Laevicaudata. Cladocera is supported as monophyletic. The combined analysis under equal weighting gave results in some respects similar to the morphological analysis. Within Phyllopoda, Cladocera, Cladoceromorpha and Spinicaudata + Cladoceromorpha are monophyletic. The combined analysis is different from the morphological analysis with respect to the position of Notostraca and Laevicaudata. Here, Laevicaudata is the sister group to the remaining Phyllopoda and Notostraca is sister group to Spinicaudata and Cladoceromorpha. A sensitivity analysis using 20 different parameter sets (different insertion-deletion [indel] ⁄ substitution and transversion ⁄ transition ratios) show the monophyly of Anostraca, Notostraca, Laevicaudata, Spinicaudata, Cladoceromorpha, Cladocera, and within Cladocera, of Onychopoda and Gymnomera under all or almost all (i.e., 19 of 20) parameter sets. Analyses with an indel-to-transversion ratio up to 2 result in monophyletic Phyllopoda, with Laevicaudata as sister group to the remaining Phyllopoda and with Spinicaudata and Cladoceromorpha as sister groups. Almost all analyses (including those with higher indel weights) result in the same topology when only ingroup taxa are considered.Ó The Willi Hennig Society 2007.Branchiopoda comprise approximately 1180 described species of mainly freshwater dwelling crustaceans (Adamowicz and Purvis, 2005). It includes taxa with a general, archaic morphology very similar to that of some Cambrian and Devonian crustacean fossils (Anostraca, Notostraca, Spinicaudata), as well as taxa that are highly specialized for predatory, scraping, parasitism, and advanced filtration such as the water fleas (Scourfield

“…After the initial round of 20 replicates with SPR + TBR + TF was executed for the 12 parameter sets in the combined analysis of all data, the trees obtained were pooled and given to POY for a subsequent round of tree fusing, the so-called sensitivity analysis tree fusing (SATF; Boyer et al, 2005).…”
