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

    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.

    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.

  3. 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.

    European water frogs of the Pelophylax esculentus complex demonstrate unusual genetic phenomena associated with hybridization, clonality and polyploidy. The Seversky Donets River drainage in north-eastern Ukraine is inhabited by diploid and triploid hybrid P. esculentus and only one parental species P. ridibundus. Based on the presence of various types of hybrids, all populations studied were divided into three geographical groups. Mass occurrence of P. esculentus which produced a mixture of haploid gametes carrying one or another non-recombinant parental genome was reported for the first time.

  5. 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.
