title: Skeletal morphology of <i>Kritosaurus navajovius</i> (Dinosauria: Hadrosauridae) from the Late Cretaceous of the North American south-west, with an evaluation of the phylogenetic systematics and biogeography of Kritosaurini

description: The osteology of the hadrosaurid dinosaur <i>Kritosaurus navajovius</i> (late Campanian of southern North America) is documented in detail, and the taxonomy and phylogenetic relationships of the genus are revised. <i>Kritosaurus</i> is rediagnosed based on the extensive length of the dorsolateral margin of the maxilla and a unique combination of characters that includes a jugal with orbital constriction deeper than infratemporal one, infratemporal fenestra greater than orbit and with dorsal margin greatly elevated above dorsal orbital margin in adults, frontal participating in orbital margin, and paired caudal parasagittal processes of nasals resting over frontals. The taxonomy of numerous hadrosaurid specimens previously referred to <i>Kritosaurus</i> is reassessed; the vast majority of these cannot be positively referred to <i>Kritosaurus</i>. One exception is a specimen collected from the Cerro del Pueblo Formation that extends the geographical range of <i>K. navajovius</i> further south in Laramidia, to present-day northern Mexico. <i>Anasazisaurus</i> is regarded a junior synonym of <i>Kritosaurus</i>; their holotypes are indistinguishable from each other when considering the overlapping elements. However, many characters support distinction of <i>Naashoibitosaurus ostromi</i> as a valid taxon. <i>Kritosaurus</i>, consisting of the sister species <i>K. navajovius</i> and <i>K. horneri</i>, is deeply nested within Saurolophinae as a member of Kritosaurini. The latter clade includes also <i>Naashoibitosaurus</i>, <i>Gryposaurus</i>, and the South American <i>Secernosaurus</i>. Kritosaurini is characterized by a rostral nasal dorsal process not reaching the rostral margin of the narial foramen, frontal with triangular rostrolateral projection ending in a narrow apex (convergent in Brachylophosaurini), and a subrectangular dorsal region of infratemporal fenestra, among other characters. Kritosaurin hadrosaurids are hypothesized to have originated in southern Laramidia no later than the early Campanian. Subsequently, members of the clade reached northern Laramidia and South America via dispersal no later than the early and late Campanian, respectively.

title: Understanding morphological variation in the extant koala as a framework for identification of species boundaries in extinct koalas (Phascolarctidae; Marsupialia)

description: We document morphological variation (both geographical and sexual) in the dentition of the extant koala, <i>Phascolarctos cinereus</i>, in order to facilitate discrimination of species boundaries in extinct phascolarctids. Considerable variation is evident in dental structures previously used to diagnose several phascolarctid fossil species. Consistent patterns of morphological variation are not evident between sexes or geographic regions, with variation as great between samples as within them. Metric variation is evident between the sexes in upper molar dimensions with Victorian (southern) males significantly larger than Victorian females, although this is not reflected in lower molar dimensions or in the Queensland (northern) sample. Male koalas from southern populations generally display significantly larger molars than their northern counterparts; however this trend is not evident in female upper molar dimensions. In both males and females, some, but not all, lower molar dimensions are larger in southern populations than northern. In light of these results, a systematic revision of species of <i>Litokoala</i> suggests <i>L.</i> ‘<i>dicktedfordi</i>’ is a junior synonym of <i>L. kutjamarpensis</i>, and the poorly known <i>L. thurmerae</i> is regarded to be a <i>nomen dubium</i>. Further, we describe a partial cranium of a new species of koala from Early Miocene sediments in the Riversleigh World Heritage Area, northern Australia. <i>Litokoala dicksmithi</i> sp. nov. is the fifth koala species recorded from the diverse rainforest assemblages of Riversleigh and the third species referred to the Oligo-Miocene genus <i>Litokoala</i>. Aspects of cranial morphology, including a shortened robust rostrum and broad, irregular nasal aperture, confirm placement of <i>Litokoala</i> as sister taxon to the modern genus <i>Phascolarctos</i>. Relatively large orbits and small body size suggest the possibility that <i>L. dicksmithi</i> was nocturnal, had enhanced visual acuity, and was a more agile arboreal species than the relatively sedentary extant koala.http://zoobank.org/urn:lsid:zoobank.org:pub:EE5D13C1-47BB-4432-B281-16398A1781E1

title: The fossil record and phylogeny of the auklets (Pan-Alcidae, Aethiini)

description: The auklets <i>Aethia</i> and <i>Ptychoramphus</i> comprise the smallest known Alcidae (Aves, Charadriiformes) and have a fossil record that extends into the Miocene. The evolution of auklets is poorly understood because systematic hypotheses of relationships among extant auklets are largely incongruent, the morphology of auklet fossils has not been evaluated in detail, and extinct species of auklets have not been previously included in a phylogenetic analysis. Previously described auklet fossil remains are reviewed and two new species of auklet, <i>Aethia barnesi</i> sp. nov. and <i>Aethia storeri</i> sp. nov., are described from the Miocene and Pliocene of southern California, USA. Previously described auklet fossil remains, the two newly described extinct species of auklet, and extant species of auklets and other alcids are included in combined phylogenetic analyses of morphological and molecular sequence data. Based on the results of the phylogenetic analyses, the taxonomy of fossils referred to Aethiini is revised and the evolution of the clade is evaluated in a phylogenetic context. The osteological morphology of extinct auklets appears to be little changed from their extant relatives, suggesting that the ecological attributes of these small wing-propelled divers may also be relatively unchanged since the Miocene.http://zoobank.org/urn:lsid:zoobank.org:pub:357ECC1A-DFE5-4C72-9BF2-260A547574C4

title: A juvenile specimen of a new coelurosaur (Dinosauria: Theropoda) from the Middle–Late Jurassic Shishugou Formation of Xinjiang, People's Republic of China

description: We describe the anatomy of a new coelurosaurian theropod <i>Aorun zhaoi</i> gen. et sp. nov., from the Middle–Late Jurassic of Xinjiang, China. Histological analysis of the holotype and only known specimen shows that the new taxon is represented by the skeleton of a juvenile individual aged no more than one year. A phylogenetic analysis of theropod relationships places <i>Aorun</i> as a basal member of the Coelurosauria. Although the sole use of a sub-adult ontogenetic exemplar is potentially problematic for phylogenetic reconstruction, we show that the phylogenetic position of <i>Aorun</i> as a member of Coelurosauria is robust to the exclusion of characters known to change during theropod ontogeny. <i>Aorun</i> is the seventh theropod taxon, and temporally oldest coelurosaur, known from the Shishugou Formation, which has one of the most taxonomically diverse Jurassic coelurosaurian theropod faunas in the world.http://zoobank.org/urn:lsid:zoobank.org:pub:5CC73577-9EB3-47AB-9983-1677B278EFFD

title: Two-stage genome-wide search for epistasis with implementation to Recombinant Inbred Lines (RIL) populations

description: Gene expression data (filter.genes.csv):<br>Gene expression Arabidopsis thaliana data was downloaded from the TAIR database website (ftp://ftp.arabidopsis.org/home/tair/Microarrays/analyzed_data/affy_data_1436_10132005.zip). A sample of 211 RIL population individuals derived from a cross between two inbred accessions, Bayreuth-0 (Bay-0) and Shahdara (Sha), was used. Transcript (mRNA) levels were quantified using Affymetrix whole-genome microarrays with two replications (arrays) for each individual. The gene expression data was preprocessed by the Variance Stabilization Normalization method [31]. Traits with essentially no expression (15,566 traits) were filtered out by the EM algorithm for a mixture of univariate normal distributions (using the ‘mixtools’ R package), leaving 7244 traits for the analysis. Genetic map (genetic_map.csv):<br>The Arabidopsis Thaliana genetic map consists of 579 molecular markers. It was originally obtained from http://elp.ucdavis.edu/data/analysis/211_RILs_SFP_map/ 211_RILs_SFP_map.html. The genotypic data was preprocessed using the MultiPoint software (http://www.multiqtl.com) for the purpose of eliminating non-informative overlapping markers and those markers that cause local neighborhood instability in the map [30]. In total, 493 markers remained for the analysis.

title: Morphological Analyses of Some Micro- and Nanofibrils from Birch and Wheat Straw Sources

description: The morphological properties of nano- and microcellulose depend on the source of the particles, the preparation methods, and the processing conditions. In this study, two different kinds of microfibrillated (MFC) and nanofibrillated (NFC) celluloses were produced from wood and non-wood cellulose pulps through mechanical methods without using any chemicals. The morphological properties of the samples and feasibility of different analysis methods were investigated using a novel chromatographic washer, a field emission scanning electron microscope (FESEM), a laser diffractometer (LS), a rotational viscometer, X-ray diffractometry (WAXD) and, additionally, the degree of polymerization (DP) was assessed. The analyses showed that the formed non-wood cellulose fibrils were shorter than the wood cellulose fibrils, but wheat straw pulp comminuted to nanofibrils more easily. The low hemicelluloses content of wheat straw pulp caused the flocculation of the nanofibrils formed in homogenization. All of the analytical methods reflect morphological differences between the micro- and nanocellulose materials.
