Abstract Acer platanoides L. (Norway maple) is the most widespread native maple species in Europe, with a distribution from south and central Europe to northern Europe and Scandinavia. Acer platanoides is widespread throughout the territory of Latvia, and is mainly found in mixed broadleaf and conifer stands. The genetic diversity and differentiation of Latvian A. platanoides populations was analysed. Sampled populations were located throughout the territory of Latvia, and were selected to represent a range of ecological conditions, with differing levels of anthropogenic impact. A total of 496 individuals from 21 populations were analysed with eight microsatellite markers, which were developed from related Acer species. The obtained molecular data revealed a moderate level of polymorphism, and the analysed Latvian A. platanoides populations were moderately differentiated. This study provides an initial assessment of the genetic diversity and differentiation of Latvian A. platanoides populations, and is also one of the first reports of the analysis of A. platanoides populations using microsatellite markers. The results can be utilised to define A. platanoides genetic resource stands to ensure conservation of a wide range of germplasm.

Germline protein truncating variants (PTVs) in the FANCM gene have been associated with a 2–4-fold increased breast cancer risk in case-control studies conducted in different European populations. However, the distribution and the frequency of FANCM PTVs in Europe have never been investigated. In the present study, we collected the data of 114 European female breast cancer cases with FANCM PTVs ascertained in 20 centers from 13 European countries. We identified 27 different FANCM PTVs. The p.Gln1701* PTV is the most common PTV in Northern Europe with a maximum frequency in Finland and a lower relative frequency in Southern Europe. On the contrary, p.Arg1931* seems to be the most common PTV in Southern Europe. We also showed that p.Arg658*, the third most common PTV, is more frequent in Central Europe, and p.Gln498Thrfs*7 is probably a founder variant from Lithuania. Of the 23 rare or unique FANCM PTVs, 15 have not been previously reported. We provide here the initial spectrum of FANCM PTVs in European breast cancer cases.

The Leadership in Energy and Environmental Design (LEED) is currently intensively applied in several European countries. The aims of the present study were to compare the difference between (i) two countries from the same region (i.e., Finland vs. Sweden or Turkey vs. Spain) and (ii) two European regions (northern Europe [Finland and Sweden] vs. [Turkey and Spain]) when the LEED- New Construction (NC) 2009 Certified rating level certified projects were analyzed. We found that, in the northern and southern parts of Europe, LEED- NC 2009 credit achievements in terms of Sustainable Sites (SS), Water Efficiency (WE), Materials and Resources (MR), and Indoor Environmental Quality (EQ) were similar, whereas credit achievements in Energy and Atmosphere (EA) were different. High achievements were revealed in WE and SS, with values of 80–100% and 70–75%, respectively; intermediate achievements were revealed in EQ, with values of 40–60%; and low achievements were revealed in MR (20–40%). EA achievements were intermediate (60–65%) in northern Europe, while they were low in southern Europe (40%). This evidence can help recognize the categories that are performed with a high number of points and those that are performed with a low number of points.

This volume is a reprint of Ralph Davis’ seminal 1962 book, The Rise of the English Shipping Industry in the Seventeenth and Eighteenth Centuries. The aim was to examine the economic reasons for the growth of British shipping before the arrival of modern technology, with a particular attention on overseas trade. The study can roughly be divided into two halves. The first is an in-depth exploration the roles within the shipping industry, from shipbuilders and shipowners to seamen and masters, from an economic perspective. The second is a chapter-by-chapter review of British overseas trade with Northern Europe, Southern Europe, the Mediterranean, East India, and America and the West Indies. The final two chapters diverge from the main sections, and focus on the interplay between government, war, and shipping. Davis attaches no extra significance to any particular nation or role, and offers an even-handed approach to maritime history still considered rare in the present day. Costs, profits, voyage estimates, ship-prices, and earnings all come under close and equal scrutiny as Davis seeks to understand the trades and developments in shipping during the period. To conclude, he places the study into a broader historical context and discovers that shipping played a measured but crucial role in the development of industrialisation and English economic development. This edition includes an introduction by the series editor; Davis’ introduction and preface; seventeen analytical chapters; a concluding chapter; two appendices concerning shipping statistics and sources; and a comprehensive index.

As early as the first decades of the sixteenth century, when English and Dutch corsairs and privateers began to challenge Spain's exclusivist claims to the New World, the struggle for control over the Americas began to be couched in terms of a holy war. The Caribbean, in particular, became the arena in which the commercial, ideological and military forces of Protestant Northern Europe and Catholic Southern Europe clashed. Spanish officials commonly referred to the English and Dutch intruders as “heretics” and “Lutheran corsairs,” while Francis Drake and his fellow Elizabethan sea dogs believed that their penetration of the New World was a crusade against Popery, Catholic fanaticism and idolatry. These rivalries continued for centuries as new actors, the United States in particular, inherited some of the old roles.

A set of 44 bread wheat landraces was used to determine the efficacy of 16 amplifed fragment length polymorphism (AFLP) primers and 63 wheat simple sequence repeat (SSR) markers in identifying polymorphisms between accessions. The SSR markers detected approximately 10 alleles per locus with a mean gene diversity (Hz) of 0.63, whereas AFLP primers identified approximately 147 fragments per primer with a mean gene diversity of 0.25. A set of 54 SSR markers and 11 AFLP primers was identified as highly polymorphic (polymorphic information content (PIC) ≥ 0.5 and 0.3 for SSR and AFLP, respectively), and suitable for molecular characterisation of germplasm. Principle coordinate analysis suggested that the AFLP and SSR loci could be used to discriminate among accessions collected from North Africa and southern Europe from those collected from the Middle East. Both marker types indicate that accessions from North Africa and southern Europe, the Middle East, and southern and eastern Asia are genetically diverse. The results indicate the usefulness of the molecular markers to assess genetic diversity present within germplasm collections.

Nayak S, Dhua U, Chhotaray A, Samanta S, Sengupta C. 2018. Short Communication: Genetic diversity of fumonisin producing Fusarium isolates from rice using PCR-RFLP of IGS-rDNA region. Biodiversitas 19: 571-576. Fusarium verticillioides (Sacc.) and related species produce carcinogenic mycotoxin known as Fumonisins in several agricultural crops including rice. However, this principal food crop has been infected by genetically diverse Fusarium species. Odisha belongs to the coastal part of India and many popular rice varieties are in the food chain in this region. Many Fusarium species producing fumonisins have been found to be associated with these rice varieties. Hence, the genetic diversity of twenty eight Fumonisin producers and non producers of Fusarium pathogens in this region was carried out in the current study. The IGS regions of 28 Fusarium isolates (both fumonisin producing and non producing) were amplified and the PCR products were restriction digested with ECoRI and HhaI. The digested products were separated on PAGE and bands were visualized by Silver Nitrate Staining. The 28 isolates could be separated into 14 IGS haplotypes. The lowest similarity was detected to be of 33% between F40 and F47. A group containing 14 isolates represented the biggest haplotypes. The isolates in which the FUM gene had not been detected (fumonisin non producer) were in a separate group having 90% similarity with each other and placed consistently in separate branch from others. Presence of unique band for this group was observed at 1650bp where as absence of specific bands was observed at 380bp and 300bp. The result of this study indicated a high degree of genetic variation among 28 Fusarium isolates. PCR RFLP of IGS region was also found to be useful for diversity study in Fusarium.
