Tracing the evolutionary history of the mole, Talpa europaea , through mitochondrial DNA phylogeography and species distribution modelling
Biological Journal of the Linnean Society 114(3) 495-512.
Our understanding of the effect of Pleistocene climatic changes on the biodiversity of European mammals mostly comes from phylogeographical studies of non-subterranean mammals, whereas the influence of glaciation cycles on subterranean mammals has received little attention. The lack of data raises the question of how and to what extent the current amount and distribution of genetic variation in subterranean mammals is the result of Pleistocene range contractions/expansions. The common mole (Talpa europaea) is a strictly subterranean mammal, widespread across Europe, and represents one of the best candidates for studying the influence of Quaternary climatic oscillation on subterranean mammals. Cytochrome b sequences, as obtained from a sampling covering the majority of the distribution area, were used to evaluate whether Pleistocene climate change influenced the evolution of T. europaea and left a trace in the genetic diversity comparable to that observed in non-subterranean small mammals. Subsequently, we investigated the occurrence of glacial refugia by comparing the results of phylogeographical analysis with species distribution modelling. We found three differentiated mitochondrial DNA lineages: two restricted to Spain and Italy and a third that was widespread across Europe. Phylogenetic inferences and the molecular clock suggest that the Spanish moles represent a highly divergent and ancient lineage, highlighting for the first time the paraphyly of T. europaea. Furthermore, our analyses suggest that the genetic break between the Italian and the European lineages predates the last glacial phase. Historical demography and spatial principal component analysis further suggest that the Last Glacial Maximum left a signature both in the Italian and in the European lineages. Genetic data combined with species distribution models support the presence of at least three putative glacial refugia in southern Europe (France, Balkan Peninsula and Black Sea) during thelast glacial maximum that likely contributed to post-glacial recolonization of Europe. By contrast, the Italian lineage remained trapped in the Italian peninsula and, according to the pattern observed in other subterranean mammals, did not contribute to the recolonization of northern latitudes

In this study we present the most complete description of color variation, morphometric and meristic characters for the rare deep-sea North Atlantic Jensen’s skate Amblyraja jenseni, based on analyses of a wide range of accessible material. Comparisons of external morphological characters of male and female specimens of varying sizes and from different regions of the North Atlantic indicated regional morphological differences likely due to prolonged geographic isolation of local populations of this species. The vast majority of individuals exhibited a “dark” coloration, with a less common “light” coloration observed particularly among skates from the waters of the northeast and northwest Atlantic. Only dark-colored skates were found in the waters of the Mid-Atlantic Ridge. We also provide new data on the habitat, vertical distribution and size of the Jensen’s skate.

Harmonia axyridis (Coleoptera: Coccinellidae) in Asia: a re-examination of the native range and invasion to southeastern Kazakhstan and Kyrgyzstan
Harmonia axyridis (Pallas) is an invasive ladybird spreading in several continents. It is native to East Asia, but its range in Asia has until now been poorly understood. The most complete map of the range of Harmonia axyridis in Asia has been compiled (432 localities). Harmonia axyridis occurs in the south-east of West Siberia, the south of East Siberia, the south of Russian Far East, the east of Kazakhstan, the north of Kyrgyzstan, Mongolia, China, North Korea, South Korea, Japan, and the north of Vietnam. Southeastern Kazakhstan and the north of Kyrgyzstan are not a part of the native range: the large Balkhash Desert is situated between this mountainous region and the nearest part of the native range (Altai mountains). The analysis of dates and places of findings indicates that Harmonia axyridis appeared in southeastern Kazakhstan and Kyrgyzstan after the construction of the Turkestan-Siberian Railway. It is hypothesized that the beetles crossed the desert along this railway.

All around the globe, humans have greatly altered the abiotic and biotic environment with ever-increasing speed. One defining feature of the Anthropocene epoch1, 2 is the erosion of biogeographical barriers by human-mediated dispersal of species into new regions, where they can naturalize and cause ecological, economic and social damage3. So far, no comprehensive analysis of the global accumulation and exchange of alien plant species between continents has been performed, primarily because of a lack of data. Here we bridge this knowledge gap by using a unique global database on the occurrences of naturalized alien plant species in 481 mainland and 362 island regions. In total, 13,168 plant species, corresponding to 3.9% of the extant global vascular flora, or approximately the size of the native European flora, have become naturalized somewhere on the globe as a result of human activity. North America has accumulated the largest number of naturalized species, whereas the Pacific Islands show the fastest increase in species numbers with respect to their land area. Continents in the Northern Hemisphere have been the major donors of naturalized alien species to all other continents. Our results quantify for the first time the extent of plant naturalizations worldwide, and illustrate the urgent need for globally integrated efforts to control, manage and understand the spread of alien species.

Megadenia Maxim. is a small genus of the Brassicaceae endemic to East Asia with three disjunct areas of distribution: the eastern edge of the Qinghai-Tibetan Plateau, the Eastern Sayan Mountains in southern Siberia, and Chandalaz Ridge in the southern Sikhote-Alin Mountains. Although distinct species (M. pygmaea Maxim., M. bardunovii Popov, and M. speluncarum Vorob., Vorosch. and Gorovoj) have been described from each area, they have lately been reduced to synonymy with M. pygmaea due to high morphological similarity. Here, we present the first molecular study of Megadenia. Using the sequences of 11 noncoding regions from the cytoplasmic (chloroplast and mitochondrial) and nuclear genomes, we assessed divergence within the genus and explored the relationships between Megadenia and Biscutella L. Although M. bardunovii, M. speluncarum, and M. pygmaea were found to be indiscernible with regard to the nuclear and mitochondrial markers studied, our data on the plastid genome revealed their distinctness and a clear subdivision of the genus into three lineages matching the three described species. All of the phylogenetic analyses of the chloroplast DNA sequences provide strong support for the inclusion of Megadenia and Biscutella in the tribe Biscutelleae. A dating analysis shows that the genus Megadenia is of Miocene origin and diversification within the genus, which has led to the three extant lineages, most likely occurred during the Early-Middle Pleistocene, in agreement with the vicariance pattern. Given the present-day distribution, differences in habitat preferences and in some anatomical traits, and lack of a direct genealogical relationship, M. pygmaea, M. bardunovii, and M. speluncarum should be treated as distinct species or at least subspecies.

Description and phylogenetic position of the first abyssal solitary kamptozoan species from the Kuril-Kamchatka trench area: Loxosomella profundorum sp. nov. (Kamptozoa: Loxosomatidae)
Deep Sea Research Part II: Topical Studies in Oceanography Forthcoming.
One of two orders of a small phylum Kamptozoa, Solitaria, consisting of one family Loxosomatidae of about 140 species, has never been recorded deeper than 700m. All known for the north-western Pacific loxosomatids (about 17 species) occur in shallow waters. The first abyssal solitary kamptozoan, Loxosomella profundorum sp. nov. is described herein. It was collected during the German–Russian deep-sea expedition KuramBio aboard RV Sonne in the summer of 2012 in the abyssal plain adjacent to the Kuril-Kamchatka Trench. It is the deepest finding of Kamptozoa to date. The new species was found living on the anthozoan polyp Corallimorpharia. L. profundorum sp. nov. is a largest solitary kamptozoan species, up to 4mm in length, with a stalk of up to 3.5 mm, with 10–12 tentacles, with two conspicuous lateral papillae, and a row of glandular cells in its stalk. A preliminary molecular phylogenetic analysis based on partial 18S rDNA indicated that L. profundorum sp. nov. is a sister clade to the clade, which includes other Loxosomella and two species of Loxomitra.

A precise knowledge of the spatial distribution of taxa is essential for decision-making processes in land management and biodiversity conservation, both for present and under future global change scenarios. This is a key base for several scientific disciplines (e.g. macro-ecology, biogeography, evolutionary biology, spatial planning, or environmental impact assessment) that rely on species distribution maps. An atlas summarizing the distribution of European amphibians and reptiles with 50 × 50 km resolution maps based on ca. 85 000 grid records was published by the Societas Europaea Herpetologica (SEH) in 1997. Since then, more detailed species distribution maps covering large parts of Europe became available, while taxonomic progress has led to a plethora of taxonomic changes including new species descriptions. To account for these progresses, we compiled information from different data sources: published in books and websites, ongoing national atlases, personal data kindly provided to the SEH, the 1997 European Atlas, and the Global Biodiversity Information Facility (GBIF). Databases were homogenised, deleting all information except species names and coordinates, projected to the same coordinate system (WGS84) and transformed into a 50 × 50 km grid. The newly compiled database comprises more than 384 000 grid and locality records distributed across 40 countries. We calculated species richness maps as well as maps of Corrected Weighted Endemism and defined species distribution types (i.e. groups of species with similar distribution patterns) by hierarchical cluster analysis using Jaccard’s index as association measure. Our analysis serves as a preliminary step towards an interactive, dynamic and online distributed database system (NA2RE system) of the current spatial distribution of European amphibians and reptiles. The NA2RE system will serve as well to monitor potential temporal changes in their distributions. Grid maps of all species are made available along with this paper as a tool for decision-making and conservation-related studies and actions. We also identify taxonomic and geographic gaps of knowledge that need to be filled, and we highlight the need to add temporal and altitudinal data for all records, to allow tracking potential species distribution changes as well as detailed modelling of the impacts of land use and climate change on European amphibians and reptiles.

Shallow-Water Northern Hemisphere Jaera (Crustacea, Isopoda, Janiridae) Found on Whale Bones in the Southern Ocean Deep Sea: Ecology and Description of Jaera tyleri sp. nov.
PloS one 9(3) e93018.
The skeleton of a natural whale fall discovered in the Southern Ocean at 1,445 m was densely covered by one small, janirid isopod. Jaera tyleri sp. nov. is the first of its genus found in the southern hemisphere and in the deep sea and is described herein. Morphological and molecular investigations revealed the systematic position of this species new to science. Phylogenetic analysis of the 18S locus confirms that this species falls in a strongly supported monophyletic clade of Jaera species. The whale bone habitat of J. tyleri sp. nov. is quite different from those of other species of the genus Jaera. The analysis of bathymetric and distribution patterns of the Janiridae in general and Jaera specifically confirm the unusualness of the habitat for this isopod species. The abundance of J. tyleri sp. nov. on the whale bones and its absence from other nearby habitats suggests it to be a whale-fall specialist. The analysis of the size-frequency distributions of J. tyleri sp. nov. suggests multimodal population structure with continuous breeding activity throughout the year. The fecundity of the species is low but in line with reduced fecundity observed in polar and small-sized isopods.

Range expansion of Agrilus convexicollis in European Russia expedited by the invasion of the emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae)
Biological Invasions Forthcoming.
The jewel beetle Agrilus convexicollis Redtenbacher, 1849 (Buprestidae) occurs in many European and North Mediterranean countries and feeds mainly on dying shoots and branches of ash trees (Fraxinus excelsior, F. ornus and F. oxyphylla). A range map of A. convexicollis with 479 exact localities from the literature and museum collections is compiled. Historically, this species was not known to be present in the central region of European Russia. Since 2007, however, specimens of A. convexicollis have been collected in seven central European Russia localities, effectively expanding the northern border of the previously known range by approximately 665 km. All recently established localities of A. convexicollis are within the region invaded by emerald ash borer (A. planipennis Fairmaire), an East Asian pest of ashes that was first detected in European Russia in 2003. In addition, almost all A. convexicollis specimens from central European Russia (both adults and larvae) were collected from declining F. pennsylvanica (an introduced North American ash) infested with A. planipennis. This is a new host record for A. convexicollis. We suspect that the recent range expansion of A. convexicollis in central European Russia has been facilitated by the A. planipennis invasion, which has caused widespread decline and mortality of ash trees in the region. This work illustrates how the invasion of one species can facilitate the range expansion of another.
