    1. Left, right or both? Estimating and improving accuracy of one-side-only geometric morphometric analyses of cranial variation

      Procrustes-based geometric morphometrics is the leading method in quantitative studies of biological form. Hundreds of analyses on bilaterally symmetric structures have been performed by using landmarks on just one side to speed up data collection and reduce dimensionality. Using 10 samples of mammalian crania (N > 500), this study shows that this expedient may not always be accurate, while the simple reconstruction of the missing side, by mirror reflection of the available one, might lead to improved accuracy and better visualization. Shape change in a sample of dorsal marmot crania: (a) left-side landmarks and (b,c) visualization of individual differences using grids and wireframes (links connecting landmarks pairwise) using (b) only the left side or (c) mirroring the left side to reconstruct the right side.

    1. Evolutionary history of the Persian Jird, Meriones persicus, based on genetics, species distribution modelling and morphometric data

      The phylogeographical history and taxonomy of the Persian Jird, Meriones persicus, in Iran were investigated. Analysing mitochondrial DNA sequences, we detected four genetic lineages. The genetic structure seems to fit the topography and biogeography of Iran and emphasizes the role of deserts as barriers to gene flow. All divergent events probably occurred during the last 1.4 My, suggesting that climatic changes probably trigger diversification. Potential refugial areas persisted during glacial periods in north-western Zagros, north-eastern Alborz and Kohrud Mountains.

    1. Evolutionary systematics and biogeography of the arid habitat-adapted rodent genus Gerbillus (Rodentia, Muridae): a mostly Plio-Pleistocene African history

      The systematics of the arid-adapted Old World Gerbillus rodent genus, as well as the timing and geographical pattern of the evolutionary history of this group, remain largely unknown. Based on mitochondrial (cyt b) and nuclear (IRBP) sequences from specimens of 21 species, we evidenced four major clades within Gerbillus, for which we propose a subgenus rank. We showed that the emergence of the genus dates back to the end of the Miocene and that most subsequent diversification events occurred during the Pleistocene, mainly in Africa.

    1. Parthenogenesis in Hexapoda: Entognatha and non-holometabolous insects

      Alisa O. Vershinina and Valentina G. Kuznetsova

      Version of Record online: 24 JUL 2016 | DOI: 10.1111/jzs.12141

      In our study, we review the development without fertilization in Hexapoda, including Entognatha, ‘Apterygota’ and non-holometabolous insect orders. This type of development is most frequently observed in Phasmatodea, Psocoptera, Thysanoptera and Hemiptera. Different modes of parthenogenesis are associated with change in ploidy level (arrhenotoky with male haploidy, apomixis with polyploidy). The majority of cases are examples of facultative thelytoky. Endosimbiont-induced sex conversion seems to be a very rare event. Furthermore, the reports about induced parthenogenesis often lack direct evidence.

    1. Photogrammetry: a useful tool for three-dimensional morphometric analysis of small mammals

      Francesc Muñoz-Muñoz, Mirsha Quinto-Sánchez and Rolando González-José

      Version of Record online: 24 MAY 2016 | DOI: 10.1111/jzs.12137

      Many studies assessing the shape of 3D structures of small mammals still use 2D data for budgetary reasons. Photogrammetry, which is considered a low-cost method, has not been applied to the study of small mammals. We test the suitability of photogrammetry to obtain 3D landmarks from mouse skulls. Our results show that photogrammetry is a precise technique for 3D shape analysis of small mammals and that it is accurate for obtaining linear measurements between 3D landmarks.

    1. The evolution of insect sperm − an unusual character system in a megadiverse group

      The phylogenetic information content of insect spermatozoa is formally evaluated for the first time. For this purpose, 77 sperm characters are coded for cladistic analyses. Parsimony and Bayesian analyses are used and compared. Sperm characters alone support few major insect clades (Hexapoda, Dicondylia, Polyneoptera, Psocodea). Important innovations are the formation of mitochondrial derivatives and the acquisition of accessory microtubules. Reliable results are obtained when character transformations are reconstructed using a phylogeny based on extensive molecular data.

    2. Additional insights into phylogenetic relationships of the Class Ophiuroidea (Echinodermata) from rRNA gene sequences

      Recent systematic investigations of ophiuroids have promoted major departures from established taxonomy. To provide additional insights into ophiuroid evolutionary relationships, we analyzed ribosomal sequence data from a mitochondrial gene (16S rRNA) and a nuclear gene (18S rRNA) from 39 ophiuroids representing 14 of the 18 families. Main findings from our study include support for a polyphyletic Ophiomyxidae, paraphyletic Amphiuridae, monophyletic Euryalida, a sister group relationship between the Ophiactidae and Ophiotrichidae, and a clade comprised of the Amphiuridae and Amphilepididae. Relationships within the families Gorgonocephalidae, Ophiuridae, Ophiodermatidae and Ophiomyxidae are discussed.

    3. Patterns of morphological variation among populations of the widespread annual killifish Nothobranchius orthonotus are independent of genetic divergence and biogeography

      Nothobranchius orthonotus is an annual killifish with extensive distribution. We tested morphological divergence among its populations forming three deep mitochondrial lineages using linear and geometric morphometry. We show that body-shape variation among the populations and between genetic groups of this species is high but not congruent with the separation into mitochondrial lineages. We therefore propose N. orthonotus to be a single species with an extensive geographic range, strong population genetic structure and high morphological variability.
