Poplars are trees of the angiosperm genus Populus , a group of generally diploid, dioecious, and deciduous pioneers that are widespread in forests around the Northern Hemisphere. Canada is a centre of poplar abundance and diversity, with 7 of the 29 global Populus species occurring naturally, and other species being introduced. Numerous interspecific hybrids also occur, including native hybrids that create centres of biodiversity, and artificial hybrid poplars that are planted for wood and fiber production, as well as for environmental and landscape applications. This paper introduces poplars and their distribution across Canada and explores Canadian and international contributions to poplar research. It also discusses papers of the special issue Poplar Research in Canada in the November 2007 and December 2007 issues of the Canadian Journal of Botany, which contains a collection of 19 contributions from Canadian institutions that report on a diverse range of topics including genomics and molecular biology, physiology, ecology, population genetics, and systematics. Many of these contributions address issues pertinent to silviculture and other applications, and one article chronicles poplar research and poplar utilization in Canada. These studies that appear in this special issue reflect the growing international emphasis on poplar, not only as an important and widespread group of trees, but also as a model that provides broader insights relevant to fundamental and applied sciences involving trees and forest systems.

This special issue includes a selection of papers presented at the 2nd Vienna Workshop on Affix Order held in Vienna, Austria on June 4–5, 2009. The workshop was in honor of Wolfgang U. Dressler on the occasion of his 70th birthday. However, this special issue differs from the classical Festschrift dedicated to a renowned scholar and is ‘more special’ in two respects at least: 1) not all authors are Dressler's friends and colleagues, some of them are only indirectly related to him, through his students; and 2) since the papers were presented at a topic-oriented workshop, they are thematically uniform. In other words, this special issue is a kind of scientific genealogy in terms of affix ordering. Thus, the title Affixes and bases should be understood in two ways: literally – affixes and bases as linguistic notions, and metaphorically – affixes and bases as linguists related directly and indirectly to a prominent base: Wolfgang U. Dressler.

The Special Issue of the Manufacturing Engineering Society 2020 (SIMES-2020) has been launched as a joint issue of the journals “Materials” and “Applied Sciences”. The 14 contributions published in this Special Issue of Applied Sciences present cutting-edge advances in the field of Manufacturing Engineering focusing on advances and innovations in manufacturing processes; additive manufacturing and 3D printing; manufacturing of new materials; Product Lifecycle Management (PLM) technologies; robotics, mechatronics and manufacturing automation; Industry 4.0; design, modeling and simulation in manufacturing engineering; manufacturing engineering and society; and production planning. Among them, the topic “Manufacturing engineering and society” collected the highest number of contributions (representing 22%), followed by the topics “Product Lifecycle Management (PLM) technologies”, “Industry 4.0”, and “Design, modeling and simulation in manufacturing engineering” (each at 14%). The rest of the topics represent the remaining 35% of the contributions.

Abstract The interest in morphology and its interaction with the other grammatical components has increased in the last twenty years, with new approaches coming into stage so as to get more accurate analyses of the processes involved in morphological construal. This special issue is a valuable contribution to this field of study. It gathers a selection of five papers from the Morphology and Syntax workshop (University of Girona, July 2017) which, on the basis of Romance and Latin phenomena, discuss word structure and its decomposition into hierarchies of features. Even though the papers share a compositional view of lexical items, they adopt different formal theoretical approaches to the lexicon-syntax interface, thus showing the benefit of bearing in mind the possibilities that each framework provides. This introductory paper serves as a guide for the readers of this special collection and offers an overview of the topics dealt in each contribution.

AbstractBy the early 2010s, a number of Malawian poets in their twenties had begun to substitute the elliptical expression of earlier generations with a language that resonated with popular idioms. As poetry directed at ‘the people’, its medium is spoken word rather than print, performed to live audiences and distributed through CDs, radio programmes and the internet. Crafted predominantly in Chichewa, the poems also address topics of popular interest. The selection of poetry presented here comes from a female and a male poet, who, unbeknown to each other, prepared poems sharply critical of homosexuality and what they regarded as its foreign and local advocacy. The same poets have also gained success for their love poems, which have depicted intimate desires in remarkably compatible ways for both women and men. The poets who performed ‘homophobic’ verse went against popular gender stereotypes in their depictions of romantic love and female and male desires. This introductory essay, as a contribution toAfrica's Local Intellectuals series, discusses the aesthetic challenges that the new poets have launched in the context of Malawi's modern poetry. With regard to gender relations in their love poems, the introduction also considers the poets’ possible countercultural contribution despite their avowed commitment to perform for ‘the people’.

Shell repairs resulting from presumed failed predation are documented in gastropods from the Late Ordovician (Cincinnatian; Richmondian) mid-to-upper Kagawong Submember of the Georgian Bay Formation on Manitoulin Island, Ontario, Canada. The bryozoan–mollusc biota and associated sediments generally suggest nearshore, shallow (<10 m), low energy (lagoonal), and perhaps mesotrophic to eutrophic conditions. Two sample sets from this unit have been studied for shell repair. One of the more commonly applied estimates of shell repair frequencies involves division of the number of individuals with at least one scar by the total number of individuals in the sample (the Individuals with scars method). Using this calculation, 207 specimens of Lophospira trilineata Ulrich and Scofield yielded a shell repair frequency of 4.8%; in 28 specimens of Trochonemella sp. the shell repair frequency was 35.7%. Repairs in Trochonemella occur primarily in the larger size class, suggesting that a size refuge was achieved by this species. Low repair frequencies in L. trilineata suggest predation with a higher success rate or fewer encounters. This study demonstrates that the paradigm of a standardized low level of shell repair in Ordovician and Silurian gastropods is oversimplistic and a range of frequency rates can be expected.

The discovery and development of multicoloured fluorescent proteins has led to the exciting possibility of observing a remarkable array of subcellular structures and dynamics in living cells. This minireview highlights a number of the more common fluorescent protein probes in plants and is a testimonial to the fact that the plant cell has not lagged behind during the live-imaging revolution and is ready for even more in-depth exploration.

In this article the rationale of this special issue is provided and the different contributions are introduced. The assumption is that there are strong similarities between the recent political and social transitions in South Africa and Germany and the reactions, both emotional and literary, of the people involved. Broadly, the transitions are described as a movement from external (or violent) to internal (or ideological) social control, though this must be modified by the various constructions the contributors put on the transition. The main themes and questions of the transitions are synthesized, highlighting the marked similarities the different contributions reveal. The most important of these are the relation to the past, problems of identity, projections of the new and the internal contradictions of nationalist discourse (which informs the process of transition). In conclusion, the similarities and differences between the two transitions indicated by this special issue, are discussed. The assumption of strong similarities between the two seems to hold, it is argued, but much more research into the matter is needed.
