Vital rate estimates for the common eider Somateria mollissima, a data-rich exemplar of the seaduck tribe

Alex Nicol-Harper, Kevin Wood, Antony Diamond, Heather Major, Aevar Petersen, Grigori Tertitski, C. Patrick Doncaster, Thomas Ezard & Geoff Hilton
This database contains estimates of the following vital rates (as required to parameterise matrix population models), for the common eider (Somateria mollissima): 1st year survival (measured either from hatching, or from fledging, to 1 year old); 2nd year survival; adult annual survival; first breeding (both age-specific recruitment probability, and breeding propensity across potential recruitment ages); breeding propensity of established female breeders; clutch size; hatching success; and fledging success. These estimates are drawn from 134 studies,...

Southon, Alexander Burdin, Ming-Shan Wang, Sonja Grunewald, Wilfried Rosendahl, Ulrich Joger, Sereina Rutschmann, Thomas B. Hildebrandt, Guido Fritsch, James A. Estes, Janet Kelso, Love Dalén, Michael Hofreiter, Beth Shapiro & Torsten Schöneberg
Steller’s sea cow, an extinct sirenian and one of the largest Quaternary mammals, was described by Georg Steller in 1741 and eradicated by humans within 27 years. Here, we complement Steller’s descriptions with paleogenomic data from 12 individuals. We identified convergent evolution between Steller’s sea cow and cetaceans but not extant sirenians, suggesting a role of several genes in adaptation to cold environments. Among these are inactivations of lipoxygenase genes, which in humans and mouse...

On the deformation of a composite rod in the framework of gradient thermoelasticity

А.О. Vatulyan & S.А. Nesterov
The gradient thermoelasticity problem for a composite rod based on the applied one-parameter model is investigated. To find the Cauchy stresses, the Vishik-Lyusternik asymptotic approach is used, taking into account the presence of boundary-layer solutions in the vicinity of the rods' boundaries and interface. A new dimensionless parameter equal to the ratio of the second rod length and the gradient parameter are introduced. Simplified formulas are constructed in order to find the distribution of the...

STUDY OF THE INFLUENCE OF TECHNOLOGICAL FEATURES OF LASER STEREOLITHOGRAPHY PROCESS ON FUNCTIONAL CHARACTERISTICS OF PARTS

V.V. Vnuk, E.V. Ippolitov, S.V. Kamaev, M.A. Markov, A.A. Nikulenko, M.M. Novikov & S.A. Cherebylo
The article reports on the effect the building orientation of the part, produced by laser stereolithography technology, has on achieving its best functional characteristics. Based on the example of IPLIT-3 and IPLIT-4 resins, the study shows that in contrast to the literature data on other commercial photocurable resins (PCRs), there is no definite advantage of the vertical orientation of the test samples compared to their horizontal orientation for obtaining the best values of the manufactured...

Lophozia svalbardensis (Lophoziaceae) in continental North America, Greenland and Siberia, its identity, variation, and differentiation

Alexey Potemkin & Anna Vilnet
Lophozia excisa var. succulenta (≡ Lophoziopsis excisa var. succulenta) is a synonym of Lophozia svalbardensis. This conclusion is based on morphological investigation and a subsequent molecular-genetic study which revealed an absence of variability amon nucleotide sequences of ITS1-2 nrDNA and trnL-F cpDNA in specimens from Arctic Alaska, west Siberian Arctic and Svalbard. Lophozia svalbardensis is reported for the first time for continental North America, Greenland and Siberia based on revised data on the distribution of...

DNA barcodes combined with multi-locus data of representative taxa can generate reliable higher-level phylogenies

Gerard Talavera, Vladimir Lukhtanov, Naomi Pierce & Roger Vila
Taxa are frequently labeled incertae sedis when their placement is debated at ranks above the species level, such as their subgeneric, generic, or subtribal placement. This is a pervasive problem in groups with complex systematics due to difficulties in identifying suitable synapomorphies. In this study, we propose combining DNA barcodes with a multilocus backbone phylogeny in order to assign taxa to genus or other higher-level categories. This sampling strategy generates molecular matrices containing large amounts...

Landscape genomics of a widely distributed snake (Dolichophis caspius, Gmelin, 1789) across Eastern Europe and Western Asia

Sarita Mahtani-Williams, William Fulton, Amelie Desvars-Larrive, Sara Lado, Jean Elbers, Bálint Halpern, Dávid Herczeg, Gergely Babocsay, Boris Lauš, Zoltán Tamás Nagy, Daniel Jablonski, Oleg Kukushkin, Pablo Orozco-TerWengel, Judit Vörös & Pamela Burger
Across the distribution of the Caspian whipsnake (Dolichophis caspius), populations have become increasingly disconnected due to habitat alterations. To understand population dynamics and the adaptive potential of this widespread but locally endangered snake, we investigated population structure, admixture and effective migration patterns. We took a landscape-genomic approach to identify selected genotypes associated with environmental variables relevant to D. caspius. With double-digest restriction-site associated DNA (ddRAD) sequencing of 53 samples resulting in 17,518 single nucleotide polymorphisms...

Deformation instability in crystalline alloys: Luders bands

G.F. Sarafanov & Yu.G. Shondin
A mechanism of localization of plastic deformation at high temperatures is investigated in the framework of the autowave model. A model of the formation and propagation of Luders bands is proposed. It is established that a Luders band is a wavefront of the plastic deformation rate. From this article's point of view, the conditions for the formation of a Luders band are decisive for the interpretation of the fluidity serration. The critical value of the...

Ancient horse genomes reveal the timing and extent of dispersals across the Bering Land Bridge

Alisa Vershinina, Peter Heintzman, Duane Froese, Grant Zazula, Molly Cassatt-Johnstone, Love Dalén, Clio Der Sarkissian, Shelby Dunn, Luca Ermini, Cristina Gamba, Pamela Groves, Joshua Kapp, Daniel Mann, Andaine Seguin-Orlando, John Southon, Mathias Stiller, Matthew Wooller, Gennady Baryshnikov, Dmitry Gimranov, Eric Scott, Elizabeth Hall, Susan Hewitson, Irina Kirillova, Pavel Kosintsev, Fedor Shidlovsky … & Beth Shapiro
The Bering Land Bridge (BLB) last connected Eurasia and North America during the Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations of a once wide-ranging group, the caballine horses (Equus spp.). Using a panel of 187 mitochondrial and...

Original CT image stacks of five fossil petrosal bones from Siberia, 3D PDF files of reconstructed endocasts, blood vessels and innervation patterns, 3D PDF instruction file, STL files of the petrosals

Julia A. Schultz, Irina Ruf, Alexander O. Averianov, Rico Schellhorn, Alexey V. Lopatin & Thomas Martin
Five partially preserved mammaliaform petrosals recovered from Middle Jurassic sediments of the Berezovsk coal mine (Krasnoyarsk Krai, Russia) show similarities to other early mammaliaforms like the morganucodontan Morganucodon and the docodontan Haldanodon in having an inflated promontorium, and a curved and apically inflated cochlear canal. But they are distinct from dryolestoid and derived mammalian petrosals by the weak coiling of the cochlear duct and the presence of a perilymphatic foramen with an open perilymphatic sulcus....

The dry grasslands (Festuco-Brometea) of the North Caucasus: first data on numerical classification and biodiversity patterns

Denys Vynokurov, Tatiana Lysenko, Zoya Dutova, Dmitriy Shylnikov, Galina Doroshina, Irina Urbanavichene, Gennadii Urbanavichus & Nelly Tsepkova
The North Caucasus is still one of the least studied regions in Europe regarding syntaxonomy. We investigated dry grasslands in the central part of the North Caucasus, namely in the Stavropol Kray region of Russia. We sampled 47 vegetation plots (relevés) of 10 m2 size (3.16 × 3.16 m) at elevations from 470 to 1150 m a.s.l. To determine the scale-dependent species richness patterns, we recorded five nested-plot series of 0.0001 to 100 m² in...

Apuleius’ Venus and Speech Characterization

Svetlana Dubova
The article explores the character of Venus in Apuleius’ story of Cupid and Psyche, as well as the lexical tools used for describing her actions and conveying her speech. Venus is one of the main characters; her speeches take prominent positions in the story and require special attention. Although the phenomenon of speech characterization in Latin literature is occasional, it may be assumed that the character of Venus is distinguished by archaic vocabulary. We see...

Ἰφιάνασσα: A Lost Homeric Reading in Lucian?

Maria N. Kazanskaya
The article examines Lucian’s source for the name of the Nereid in DMar. 14, Iphianassa (Ἰφιάνασσα). This name does not appear in the two classical lists of Nereids in Homer (Il. 18. 37–49) and in Hesiod (Th. 240–264), from which Lucian drew the names of all other Nereids of his Dialogi marini, and Lucian is the sole ancient source to mention a Nereid by that name. This led scholars to suspect that the name may...

Cicero’s Kritik an das antonische Provokationsgesetz

Natalia Kuznetsova
Cic. Phil. I, 21–23 is the only source for the Antonian bill of 43 BC, which may have allowed the appeal to the people (provocatio) against the condemnation de vi et maiestatis by the jury courts. This bill is practically the only law on the appeal which dates to a relatively well-attested period and offers contemporary evidence. This sounds like a good chance to answer at least some of the many questions concerning the right...

Data from: The leaf economic and plant size spectra of European forest understory vegetation

Josep Padullés Cubino, Idoia Biurrun, Gianmaria Bonari, Tatiana Braslavskaya, Xavier Font, Ute Jandt, Florian Jansen, Valerijus Rašomavičius, Wolfgang Willner & Milan Chytrý
Forest understories play a vital role in ecosystem functioning and the provision of ecosystem services. However, the extent to which environmental conditions drive dominant ecological strategies in forest understories at the continental scale remains understudied. Here, we used ~29,500 forest vegetation plots sampled across Europe and classified into 25 forest types to explore the relative role of macroclimate, soil pH, and tree canopy cover in driving abundance-weighted patterns in the leaf economic spectrum (LES) and...

Next-generation phylogeography of the banded newts (Ommatotriton): A phylogenetic hypothesis for three ancient species with geographically restricted interspecific gene flow and deep intraspecific genetic structure

Isolde Van Riemsdijk, J. W. Arntzen, Wiesław Babik, Sergé Bogaerts, Michael Franzen, Konstantinos Kalaentzis, Spartak N. Litvinchuk, Kurtuluş Olgun, Jan Willem P.M. Wijnands & Ben Wielstra
Technological developments now make it possible to employ many markers for many individuals in a phylogeographic setting, even for taxa with large and complex genomes such as salamanders. The banded newt (genus Ommatotriton) from the Near East has been proposed to contain three species (O. nesterovi, O. ophryticus and O. vittatus) with unclear phylogenetic relationships, apparently limited interspecific gene flow and deep intraspecific geographic mtDNA structure. We use parallel tagged amplicon sequencing to obtain 177...
