Phylogeny and biogeography of the northern temperate genus Dracocephalum s.l. (Lamiaceae)

Ya-Ping Chen, Turginov Turdimatovich, Maxim Nuraliev, Predrag Lazarević, Bryan Drew & Chun-Lei Xiang
The northern temperate genus Dracocephalum consists of approximately 70 species mainly distributed in the steppe-desert biomes of Central and West Asia and the alpine region of the Qinghai-Tibetan Plateau (QTP). Previous work has shown that Dracocephalum is not monophyletic and might include Hyssopus and Lallemantia. This study attempts to clarify the phylogenetic relationships, diversification patterns, and the biogeographical history of the three genera (defined as Dracocephalum s.l.). Based on a sampling of 66 taxa comprising...

Dawes, Sylvain Delzon, Alex Fajardo, Yunting Fang, Lei Fujiyoshi, Alan Gray, Rossella Guerrieri, Michael J. Gundale, David J. Hawke, Peter Hietz, Mathieu Jonard, Elizabeth Kearsley, Tanaka Kenzo, Mikhail Makarov, Sara Marañón-Jiménez, Terrence P. McGlynn, Brenden E. McNeil, Stella G. Mosher … & Katarzyna Zmudczyńska-Skarbek
Human societies depend on an Earth System that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N concentrations ([N]) and isotope ratios (15N) from more than 42,000 samples acquired over 37 years, here we show that foliar [N] declined by 8% and foliar 15N declined by 0.8 – 1.9 ‰. Examining patterns across different climate spaces, foliar 15N declined across...

Data from: Colonizing the wild west: low diversity of complete mitochondrial genomes in western North Pacific killer whales suggests a founder effect

Olga A. Filatova, Ekaterina A. Borisova, Ilya G. Meshchersky, Maria D. Logacheva, Nataliia V. Kuzkina, Olga V. Shpak, Phillip A. Morin, Erich Hoyt & Ilya G Meschersky
In the North Pacific, fish-eating R-type “resident” and mammal-eating T-type “transient” killer whales do not interbreed and differ in ecology and behavior. Full-length mitochondrial genomes (about 16.4 kbp) were sequenced and assembled for 12 R-type and 14 T-type killer whale samples from different areas of the western North Pacific. All R-type individuals had the same haplotype, previously described for R-type killer whales from both eastern and western North Pacific. However, haplotype diversity of R-type killer...

Differential activation of c-Fos and Egr1 during development of the mouse visual cortex

Alexander Lazutkin, Anna Ivanova, Pavel Rogozin, Grigori Enikolopov & Konstantin Anokhin
Critical periods (CP) in brain development are associated with profound changes in gene expression cascades. Here we examine the expression of the immediate early genes c-Fos and Egr1 at different stages of mouse visual cortex (VC) development. Mice 11, 25, and 50 days of age were maintained under standard light-dark conditions, deprived of light for 5 days, or deprived of light for 5 days and then exposed to light for 90 min. Their brains were...

Data from: Shedding light on a cryptic cavernicole: a second species of Zenkevitchia Birstein (Crustacea: Amphipoda: Typhlogammaridae) discovered via molecular techniques

Dmitry A. Sidorov, Andrey A. Gontcharov, Dmitry M. Palatov, Steven J. Taylor, Alexander A. Semenchenko, Steven Taylor & Dmitry Palatov
The Abkhazian region, in the southern foothills of the Caucasus Mountain Range, comprises a unique natural environment containing numerous subterranean habitats with relict and endemic lineages of obligate stygofauna. We aimed to assess the molecular phylogenetic relationships of Typhlogammaridae species from Balkan and Transcaucasian caves using the mitochondrial cytochrome c oxidase I (COI) in hopes of discovering previously undetected biodiversity. Our results showed molecular divergence within the genus Zenkevitchia Birstein, with two distinct groups located...

Data from: Intercontinental genetic structure and gene flow in Dunlin (Calidris alpina), a potential vector of avian influenza

Mark P. Miller, Susan M. Haig, Thomas D. Mullins, Luzhang Ruan, Bruce Casler, Alexei Dondua, H. River Gates, J. Matthew Johnson, Steve Kendall, Pavel S. Tomkovich, Diane Tracy, Olga P. Valchuk & Richard B. Lanctot
Waterfowl (Anseriformes) and shorebirds (Charadriiformes) are the most common wild vectors of influenza A viruses. Due to their migratory behavior, some may transmit disease over long distances. Migratory connectivity studies can link breeding and nonbreeding grounds while illustrating potential interactions among populations that may spread diseases. We investigated Dunlin (Calidris alpina), a shorebird with a subspecies (C. a. arcticola) that migrates from nonbreeding areas endemic to avian influenza in eastern Asia to breeding grounds in...

Data from: Candidate genes for colour and vision exhibit signals of selection across the pied flycatcher (Ficedula hypoleuca) breeding range

Paula K. Lehtonen, Toni Laaksonen, Aleksandr V. Artemyev, Eugen Belskii, Paul R. Berg, Christiaan Both, Laura Buggiotti, Stanislav Bureš, Malcolm D. Burgess, Andrey V. Bushuev, Indrikis Krams, Juan Moreno, Marko Mägi, Andreas Nord, Jaime Potti, Pierre-Alain Ravussin, Glenn Peter Sætre, Paivi Sirkiä, Wolfgang Winkel & Craig R. Primmer
The role of natural selection in shaping adaptive trait differentiation in natural populations has long been recognized. Determining its molecular basis, however, remains a challenge. Here, we search for signals of selection in candidate genes for colour and its perception in a passerine bird. Pied flycatcher plumage varies geographically in both its structural and pigment-based properties. Both characteristics appear to be shaped by selection. A single-locus outlier test revealed two of fourteen loci to exhibit...

These are genotype calls for Gulf of Maine samples associated with the paper 'Species identification based on a semi-diagnostic marker: evaluation of a simple conchological test for distinguishing blue mussels Mytilus edulis L. and M. trossulus Gould'.

Global flyway evolution in red knots Calidris canutus and genetic evidence for a Nearctic refugium

Jesse Conklin, Yvonne Verkuil, Phil Battley, Chris Hassell, Job Ten Horn, James Johnson, Pavel Tomkovich, Allan Baker, Theunis Piersma & Michaël Fontaine
Present-day ecology and population structure are the legacies of past climate and habitat perturbations, and this is particularly true for species that are widely distributed at high latitudes. The red knot, Calidris canutus, is an arctic-breeding, long-distance migratory shorebird with six recognized subspecies defined by differences in morphology, migration behavior, and annual-cycle phenology, in a global distribution thought to have arisen just since the Last Glacial Maximum (LGM). We used nextRAD sequencing of 10,881 single-nucleotide...

THE DEVELOPMENT OF RUSSIAN CHURCH ARCHITECTURE IN THE 1990s-2017: THE STATE AND PROSPECTS

Bogdan Ershov, Igor Ashmarov & Sergey Danilchenko
The article examines church architecture in modern Russia. The historical processes of the development of church architecture are analyzed and systematized not only from the point of view of formal stylistic but also global significance. For this purpose, for the first time, a wide range of sources containing information on the sacred component of church art and on the monuments of temple architecture was studied. At the same time, many fragments of sources were first...

Dunlin subspecies exhibit regional segregation and high site fidelity along the East Asian−Australasian Flyway

Benjamin Lagassé, Richard Lanctot, Mark Barter, Stephen Brown, Chung-Yu Chiang, Chi-Yeung Choi, Yuri Gerasimov, Steve Kendall, Joseph Liebezeit, Konstantin Maslovsky, Alexander Matsyna, Ekaterina Matsyna, David Payer, Sarah Saalfeld, Yoshimitsu Shigeta, Ivan Tiunov, Pavel Tomkovich, Olga Valchuk & Michael Wunder
The degree that individuals migrate among particular breeding, migration, and wintering sites can have important implications for prioritizing conservation efforts. Four subspecies of Dunlin (Calidris alpina) migrate along the East Asian−Australasian Flyway (EAAF). Each subspecies has a distinct and well-defined breeding range, but their migration and winter ranges are poorly defined or unknown. We assessed the migratory connectivity of 3 of these subspecies by evaluating a dataset that encompasses 57 years (1960–2017), and comprises more...

Data from: Peculiar macrophagous adaptations in a new Cretaceous pliosaurid

Valentin Fischer, Maxim S. Arkhangelsky, Ilya M. Stenshin, Gleb N. Uspensky, Nikolay G. Zverkov & Roger B. J. Benson
During the Middle and Late Jurassic, pliosaurid plesiosaurs evolved gigantic body size and a series of craniodental adaptations that have been linked to the occupation of an apex predator niche. Cretaceous pliosaurids (i.e. Brachaucheninae) depart from this morphology, being slightly smaller and lacking the macrophagous adaptations seen in earlier forms. However, the fossil record of Early Cretaceous pliosaurids is poor, concealing the evolution and ecological diversity of the group. Here, we report a new pliosaurid...

Data from: Bursts of amino acid replacements in protein evolution

Anastasia V. Stolyarova, Georgii A. Bazykin, Tatiana V. Neretina & Alexey S. Kondrashov
Evolution can occur both gradually and through alternating episodes of stasis and rapid changes. However, the prevalence and magnitude of fluctuations of the rate of evolution remains obscure. Detecting a rapid burst of changes requires a detailed record of past evolution, so that events that occurred within a short time interval can be identified. Here, we use the phylogenies of the Baikal Lake amphipods and of Catarrhini, which contain very short internal edges facilitating this...

Data from: Extensive phenotypic diversification coexists with little genetic divergence and a lack of population structure in the White Wagtail subspecies complex (Motacilla alba)

Georgy A. Semenov, Evgeniy A. Koblik, Yaroslav A. Red'kin & Alexander V. Badyaev
Geographically clustered phenotypes often demonstrate consistent patterns in molecular markers, particularly mitochondrial DNA (mtDNA) traditionally used in phylogeographic studies. However distinct evolutionary trajectories among traits and markers can lead to their discordance. First, geographic structure in phenotypic traits and nuclear molecular markers can be co-aligned but inconsistent with mtDNA (mito-nuclear discordance). Alternatively, phenotypic variation can have little to do with patterns in neither mtDNA nor nuclear markers. Disentangling between these distinct patterns can provide insight...

Data from: Transcriptome-based phylogeny of endemic Lake Baikal amphipod species flock: fast speciation accompanied by frequent episodes of positive selection

Sergey A. Naumenko, Maria D. Logacheva, Nina V. Popova, Anna V. Klepikova, Aleksey A. Penin, Georgii A. Bazykin, Anna E. Etingova, Nikolai S. Mugue, Alexey S. Kondrashov & Lev Y. Yampolsky
Endemic species flocks inhabiting ancient lakes, oceanic islands and other long-lived isolated habitats are often interpreted as adaptive radiations. Yet molecular evidence for directional selection during species flocks radiation is scarce. Using partial transcriptomes of 64 species of Lake Baikal (Siberia, Russia) endemic amphipods and two non-endemic outgroups, we report a revised phylogeny of this species flock, and analyze evidence for positive selection within the endemic lineages. We confirm two independent invasions of amphipods into...

Data from: Interspecific transfer of parasites following a range-shift in Ficedula flycatchers

William Jones, Katarzyna Kulma, Staffan Bensch, Mariusz Cichoń, Anvar Kerimov, Miloš Krist, Toni Laaksonen, Juan Moreno, Pavel Munclinger, Fred Slater, Eszter Szöllősi, Marcel E. Visser, Anna Qvarnström & Fred M. Slater
Human-induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host-parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Two competing theories, the Enemy Release Hypothesis, where invading hosts escape their original parasites; and the Novel Weapon Hypothesis, where invading hosts bring new parasites that have detrimental effects on native hosts, have been described to predict...

Data from: Ornithogenic vegetation: How significant has the seabird influence been on the Aleutian Island vegetation during the Holocene?

Olesya Smyshlyaeva, Elena Severova, Olga Krylovich, Evgeniya Kuzmicheva, Arkady Savinetsky, Dixie West & Virginia Hatfield
In the Aleutian Islands during the Holocene, terrestrial predators were actually absent; as a result, large seabird colonies thrived along the coasts or across entire islands. Bird guano enriches the soil with nitrogen, which can lead to the formation of highly modified ornithogenic (bird-formed) ecosystems. For a more detailed investigation of avian influence, we reconstructed more than 10,000-year-old vegetation dynamics of the coast of Shemya Island (Near Islands) by pollen analysis. At the initial stages...

A MicroCT Image of Silty Loam Phaeozem Albic

Dmitriy Ivonin & Timofey Kalnin
An X-ray computed tomography was carried out in two varieties of samples condition: air-dried and moistened behind the field capacity condition. To rich the last one the sample was taken after the tomography and was moistened by the excess water through the base of several filter papers. The moistening stretched in 7 full days with permanent water filling-up until the water table occurred on the base surface. Then the sample was free drained on a...

Data from: Body shrinkage due to Arctic warming reduces red knot fitness in tropical wintering range

Jan A. Van Gils, Simeon Lisovski, Tamar Lok, Włodzimierz Meissner, Agnieszka Ożarowska, Jimmy De Fouw, Eldar Rakhiemberdiev, Mikhail Y. Soloviev, Theunis Piersma & Marcel Klaassen
Reductions in body size are increasingly being identified as a response to climate warming. Here we present evidence for a case of such body shrinkage, potentially due to malnutrition in early life. We show that an avian long-distance migrant (red knot, Calidris canutus canutus), which is experiencing globally unrivaled warming rates at its high-Arctic breeding grounds, produces smaller offspring with shorter bills during summers with early snowmelt. This has consequences half a world away at...

Data from: The phylogeny of pikas (Ochotona) inferred from a multilocus coalescent approach

José Melo-Ferreira, Ana Lemos De Matos, Helena Areal, Andrey A. Lissovsky, Miguel Carneiro & Pedro J. Esteves
The clarification of the systematics of pikas (genus Ochotona) has been hindered by largely overlapping morphological characters among species and the lack of a comprehensive molecular phylogeny. Here we estimate the first multilocus phylogeny of the genus to date, by analysing 12 nuclear DNA markers (total of 7.5 Kb) in 11 species of pikas from the four classified subgenera (Pika, Ochotona, Lagotona and Conothoa) using a multispecies coalescent-based framework. The species-tree confirmed the subgeneric classification...

Data from: Juvenile divergence in adaptive traits among seven sympatric fish eco-morphs arises before moving to different lacustrine habitats

Evgeny V. Esin, Grigorii N. Markevich, Michail Yu. Pichugin & Michail Yu Pichugin
Identifying the mechanisms initiating sympatric diversification in vertebrates has remained a conceptual challenge. Here we analyze an assemblage of sympatric charr (Salvelinus malma) morphs from landlocked Lake Kronotskoe basin as a model to uncover the divergence pathways in freshwater fishes during the early life history stages. All morphs have distinct developmental biology, but a similar developmental rate retardation compared to the ancestor. Our study reveals that adult morphological differences, which acquire functionality at maturation, originate...

Data from: Morphometric analysis and taxonomic revision of Anisopteromalus Ruschka (Hymenoptera: Chalcidoidea: Pteromalidae) – an integrative approach

Hannes Baur, Yvonne Kranz-Baltensperger, Astrid Cruaud, Jean-Yves Rasplus, Alexander V. Timokhov & Vladimir E. Gokhman
We use an integrative taxonomic approach to revise the genus Anisopteromalus. In particular, we apply multivariate ratio analysis (MRA), a rather new statistical method based on principal component analysis (PCA) and linear discriminant analysis (LDA), to numerous body measurements and combine the data with those from our molecular analysis of Cytb and ITS2 genetic markers (on a subset of species) and all available published data on morphology, karyology, behavior, host associations, and geographic distribution. We...
