Published: February 2019

AbstractBACKGROUNDFor the first time, a model was applied at the global scale to investigate the effects of climate change on Dalbulus maidis. D. maidis is the main vector of three plant pathogens of maize crops and has been reported as one of the most important maize pests in Latin America. We modelled the effects of climate change on this pest using three Global Climate Models under two Representative Concentration Pathways (RCPs) using MaxEnt software.RESULTSOverall, climate change will lead to a decrease in suitable areas for D. maidis. In South America, climate change will decrease the areas suitable for the pest, especially in Brazil. However, Argentina, Chile, Colombia, Ecuador, Peru and Venezuela will have small areas that are highly suitable for the corn leafhopper. Outside the pest's range, Ethiopia, Kenya, Rwanda, Burundi and South Africa also should be concerned about the risk of corn leafhopper invasions in the future because they are projected to have conditions that are highly suitable for this insect in some areas.CONCLUSIONThis study allows the relevant countries to increase their quarantine measures and guide researchers to develop new Zea mays varieties that are resistant or tolerant to D. maidis. In addition, the maize‐stunting pathogens for the areas are highlighted in this modelling. © 2019 Society of Chemical Industry
Trapped mountain waves with a critical level just below the surface
Authors: Soufflet Clément , Lott François , Damiens Florentin 
Published: February 2019

The trapped mountain waves produced when the incident wind near the surface is small compared with its value aloft are analyzed with a theory adapted from Long (1953) and compared with fully nonlinear simulations performed with the Weather Research and Forecasting model (WRF). Although small near‐surface incident winds occur naturally in fronts via a combination of the thermal wind balance and the boundary layer, they pose at least two problems in mountain meteorology: zero surface incident winds produce no wave in the fully linear case; they also correspond to places where mountain waves have a critical level.Despite these problems, theory and WRF show that, for small mountains, trapped lee waves (a) can occur and (b) are favored when the surface Richardson number J = N
2/(∂u/∂z)2 is small. This last result is related to the theoretical fact that the surface absorption of stationary gravity waves increases when J increases. The relation with flow stability is corroborated further by the fact that the trapped lee waves resemble the Kelvin–Helmholtz (KH) modes of instability that exist when J < 0.25.For medium mountains, some aspects of the theory still hold but need to be adapted, the more intense winds and foehn that occur along the lee side of the mountain having a tendency to increase the surface flow stability. For “initially” small J, this can limit the onset of trapped lee waves, again consistent with the fact that mountain‐wave surface absorption increases with surface flow stability. For large J, the dynamics produces wave breaking on the lee side, destabilizing the flow in the wake of the mountain. In the region where the Richardson number is small, trapped waves develop despite the fact that the surface Richardson number can be quite large, suggesting that the trapped lee waves now result from an absolute instability of the wake.
A new dual CUSUM mean chart
Authors: Haq Abdul , Bibi Lubna 
Published: February 2019

AbstractThe conventional cumulative sum (CUSUM) chart is usually designed based on a known shift size. In usual practice, shift size is often unknown and can be assumed to vary within an interval. With such a range of shift size, the dual CUSUM (DCUSUM) chart provides more sensitivity than the CUSUM chart. In this paper, we propose dual Crosier CUSUM (DCCUSUM) charts with and without fast initial response features to efficiently monitor the infrequent changes in the mean of a normally distributed process. Monte Carlo simulations are used to compute the run length characteristics of one‐sided and two‐sided DCCUSUM charts. These run length characteristics are compared with those of the CUSUM, Crosier CUSUM, Shewhart‐CUSUM, and DCUSUM charts in terms of the integral relative average run length. It turns out that the proposed chart shows better performance when detecting a range of mean shift sizes. A real dataset is considered to illustrate the implementation of existing and proposed charts.
Codesign of controller, routing and scheduling in WirelessHART networked control systems
Authors: Di Girolamo Giovanni Domenico , D'Innocenzo Alessandro 
Published: February 2019

SummaryIn this paper, we provide a novel methodology to co‐design controller, scheduling and routing in a wireless control network compliant with the WirelessHART protocol. We both provide a modeling framework and derive a novel suboptimal solution to the linear‐quadratic regulator problem for a class of systems that extends Markov jump linear system considering both continuous and discrete inputs. To allow that, our results can be directly implemented in a real WirelessHART network, we setup a receding horizon optimization problem that takes into account the constraint for compliance with WirelessHART and validate our solution on a batch reactor control loop.
Phylogenetic relationships within Silene (Caryophyllaceae) section Physolychnis
Authors: Petri Anna , Oxelman Bengt 
Published: February 2019

AbstractPhylogenetic relationships within Silene sect. Physolychnis are investigated using DNA sequences from two low‐copy nuclear regions and three plastid regions. We expand the circumscription of Physolychnis to include also Siberian and Eurasian taxa, with S. zawadzkii and S. uralensis as delimiters of the section. Two main clades are identified within Physolychnis, the Siberian S. ajanensis group and an Asian/American clade. Several taxa, previously classified to sect. Odontopetalae, sect. Occidentales, and sect. Morrisonmontanae, are shown to belong to the Asian/American clade, which otherwise corresponds to Bocquet's (1969) circumscription of sect. Physolychnis. Silene sect. Physolychnis also includes several additional, mainly Asian taxa (e.g., S. davidii, S. seoulensis, S. keiskei, S. viscosa, S. quadriloba, and homoeologues from S. songarica, S. firma, and S. tolmatchevii). Several putative allopolyploids are identified, in several cases stemming from crosses between the two main clades. The two allotetraploids S. involucrata and S. sachalinensis, although morphologically and geographically distinct, have indistinguishable ancestries.
Molecular phylogeny and taxonomy of the genus Lamium L. (Lamiaceae): Disentangling origins of presumed allotetraploids
Authors: Bendiksby Mika , Brysting Anne K. , Thorbek Lisbeth , Gussarova Galina , Ryding Olof 
Published: February 2019

AbstractThis is the first comprehensive molecular investigation of the genus Lamium L. We have addressed phylogenetic relationships and presumed allopolyploid speciation by use of nuclear (NRPA2, 5S‐NTS) and chloroplast (matK, psbA‐trnH, rps16, trnL, trnL‐F, trnS‐G) DNA sequence data. Nuclear and chloroplast data were incongruent, and nuclear data showed better correlation with morphology. Bayesian and parsimony phylogenetic results show that (1) Lamium galeobdolon is sister to all remaining Lamium species; (2) Wiedemannia is nested within Lamium; (3) L. amplexicaule is polyphyletic; (4) most tetraploids are of hybrid origin; (5) L. amplexicaule var. orientale is allotetraploid; and (6) Mennema's (1989) infrageneric classification is not corroborated by molecular data. Based on the molecular results, and taking morphology into account, we suggest resurrection of two species: L. aleppicum and L. paczoskianum.
Revisiting monophyly in Haworthia Duval (Asphodelaceae): Incongruence, hybridization and contemporary speciation
Authors: Ramdhani Syd , Barker Nigel P. , Cowling Richard M. 
Published: February 2019

AbstractMolecular phylogenetic reconstructions have indicated that Haworthia is not monophyletic. Here we show, using considerably expanded datasets of both chloroplast (trnL‐trnF and psbA‐trnH intergenic spacers) and nuclear (ITS1) markers that the issue of a polyphyletic Haworthia is more complicated than previously reported. Both parsimony and bayesian analyses of cpDNA and ITS1 produced poorly resolved phylogenies, with little or no support for deeper nodes. Species of Haworthia are placed in three of the four main lineages in the cpDNA phylogeny, while in the ITS1 phylogeny Haworthia species were placed in two of the four main lineages retrieved. The cpDNA phylogeny was incongruent with that obtained from the ITS1 data, and the topology of the combined dataset reflected that obtained from the ITS1 dataset. As species of H. subg. Hexangulares and subg. Robustipedunculares have been reportedly involved in intergeneric hybridizations with other Alooideae, it is postulated that a history of ancient hybridization may account for a polyphyletic Haworthia. Hybridization is also ongoing between species within H. subg. Haworthia, and may be responsible for results indicating that some species in this subgenus are not monophyletic. This hybridization may be facilitated by the lack of effective reproductive barriers. We hypothesize that Haworthia is undergoing a contemporary and explosive radiation in southern Africa, driven in part by local adaptation to relatively fine‐grained ecological heterogeneity of soils and microclimate.
The monotypic Andean genus Fulcaldea (Compositae, Barnadesioideae) gains a new species from northeastern Brazil
Authors: Funk Vicki A. , Roque Nádia 
Published: February 2019

AbstractThe family Compositae has ca. 25,000 species and is estimated to have diverged approximately 45 Ma. Within the family, the small subfamily Barnadesioideae (91 spp.) is the sister group of the rest of Compositae. Four of its nine genera have only one species; one of these, Fulcaldea, is restricted to northern Peru and Ecuador as is its sister group, Arnaldoa (3 spp.). A new species, Fulcaldea stuessyi, is described from the Chapada Diamantina of Bahia, Brazil, a remarkable 4000 km disjunction. The new species is clearly a member of Fulcaldea sharing a number of important characters with the type, F. laurifolia, including a single‐flowered capitulum, "plumose" pappus, shrubby habit, and style with a unique swelling. It is distinguished from that species by its red corolla and pappus, greater number of series of phyllaries, and much greater length of the corolla, style, and pappus. The location of the new taxon may be the result of vicariance or long‐distance dispersal; it is named in honor of Professor Tod Stuessy.
Establishing dates of valid publication for Luigi Buscalioni's names in Saurauia (Actinidiaceae)
Authors: Kelly Lawrence M. 
Published: February 2019

AbstractLuigi Buscalioni published 119 names of species and infraspecific taxa of Saurauia in many installments over a 16‐year period from 1912 and 1927. Buscalioni's work had formal taxonomic sections, which he likely intended as place of valid publication for his names. Nevertheless, most of his names were published with diagnostic or descriptive information in many parts of his works, often earlier than his formal descriptions. The citations of names in Buscalioni's work are summarized, and dates and citations for validation of names are provided.

Relationships and evolutionary origins of polyploid Dryopteris (Dryopteridaceae) from Europe inferred using nuclear pgiC and plastid trnL-F sequence data
Authors: Juslén Aino , Väre Henry , Wikström Niklas 
Published: February 2019

AbstractTo test earlier hypotheses on the evolutionary origins of European polyploid Dryopteris, their phylogenetic relationships are investigated using nuclear pgiC and plastid trnL‐F sequence data. The nuclear pgiC region is for the first time used successfully in phylogenetic analyses of ferns, and is shown to provide appropriate variability to address species‐level questions in Dryopteris. The trnL‐F dataset is used to infer maternal relationships for the allopolyploid species and provides strong support for some of the smaller clades resolved by pgiC. Allopolyploid origins of Dryopteris carthusiana, D. cristata, and D. guanchica are supported and some, but not all, progenitors are indicated by the analyses. The results are in disagreement with the "D. semicristata" hypothesis proposed by several authors. The allopolyploid origin of D. crispifolia remained unresolved and allopolyploid origins of D. dilatata and D. filix‐mas were unsupported. This study provides the first insight in the molecular phylogeny of the diploid D. fragrans, which shows major genetic variation within the only European population of the species.
The status of Urocarpidium (Malvaceae): Insight from nuclear and plastid‐based phylogenies
Authors: Tate Jennifer A. 
Published: February 2019

AbstractAn evaluation of the taxonomic status and phylogenetic position of the monotypic genus Urocarpidium Ulbr. (Malvaceae) was undertaken using DNA sequence data. Nuclear (ITS 1 and 2) and plastid (ndhF, rpl16 intron, 3′ matK‐trnK intron) sequence data were used to reconstruct independent phylogenies for related genera of tribe Malveae, to which Urocarpidium belongs. The nuclear and plastid phylogenies indicate that Urocarpidium albiflorum is not synonymous with Tarasa operculata as previously suggested, consistent with earlier phylogenetic studies. Instead, this species is more closely related to Fuertesimalva and Palaua, although its position relative to these two genera differs in the nuclear and plastid trees. Given the unresolved phylogenetic position and unique suite of morphological characters, Urocarpidium is maintained as a monotypic genus. Full synonymy for Urocarpidium albiflorum is also provided.
A phylogenetic analysis of the genus Colchicum L. (Colchicaceae) based on sequences from six plastid regions
Authors: Persson Karin , Petersen Gitte , del Hoyo Alberto , Seberg Ole , Jørgensen Tina 
Published: February 2019

AbstractA phylogenetic analysis of the genus Colchicum (including Bulbocodium and Merendera) is presented. The phylogeny includes all but four of the 100 species and all subspecies currently recognized in the genus, two insufficiently known species (C. mirzoevae, C. stenopetalum), and one cultivated specimen (C. laetum hort.) probably of hybrid origin. The analysis is based on 292 parsimony‐informative characters derived from nucleotide sequences from six plastid regions (trnL intron, trnL‐trnF IGS, trnY‐trnD IGS, trnH‐psbA IGS, atpB‐rbcL IGS, rps16 intron) and 33 morphological, life history, and chromosomal characters. The genus Colchicum is strongly supported as monophyletic. The morphological data are considerably more homoplasious than the molecular characters, but provide added resolution to the trees derived from a combined analysis. The phylogenetic hypothesis is largely in conflict with the subgenera and sections recognized by Stefanov, and agrees better with some of the informal species groups defined by Persson in earlier publications. Additional data will be needed to resolve all relationships.
Systematics of the genusSalweenia(Leguminosae) from Southwest China with discovery of a second species
Authors: Yue Xue-Kun , Yue Ji-Pei , Yang Li-Er , Li Zhi-Min , Sun Hang 
Published: February 2019

AbstractSalweenia(Leguminosae) has long been defined as a monotypic genus. In this study we carried out comprehensive studies on populations ofS. wardiiBaker f. across its distribution range. The results showed that this species diverged into two distinct groups: plants from the Yalong Jiang valley have linear leaflets 0.07–0.14 cm wide and relatively flattened legumes, as well as a 2A karyotype asymmetry, whereas plants from the Nu Jiang and Lancang Jiang drainages have lanceolate leaflets 0.20–0.34 cm wide, undulant legumes, and a 1A karyotype asymmetry. Furthermore, molecular phylogenetic analysis of four chloroplast DNA markers (trnL‐F, rpl32‐trnL, psbA‐trnH, trnS‐G) recovered two reciprocally monophyletic clades among accessions of plants from these two areas respectively. We therefore recognize individuals ofS. wardiiin the Yalong Jiang valley as a separate species,S. bouffordianasp.nov.Salweeniathus contains two allopatrically distributed species and the genus is no longer monotypic. The origin of the disjunction between the two species is briefly discussed and it is hypothesized to have come about through vicariance, resulting of several historic river separations, reversal and capture events estimated to have taken place during the Pleistocene.
Molecular delimitation of clades within New World species of the "spiny solanums" (Solanum subg. Leptostemonum)
Authors: Stern Stephen , Agra Maria de Fátima , Bohs Lynn 
Published: February 2019

AbstractSolanum subg. Leptostemonum contains approximately 350–450 species, including the cultivated eggplant, S. melongena. Most species placed in this subgenus form a monophyletic group, the Leptostemonum clade, characterized by the presence of stellate hairs and prickles, leading to the common name of "spiny solanums". Here we present a phylogenetic analysis that circumscribes the major clades within the spiny solanums and examines the relationships among them, with an emphasis on New World species. Of particular interest is the clarification of the clade limits and species composition of groups that have not been well‐sampled. We also increase sampling of taxa that have been previously analyzed in molecular studies, namely those in the Torva, Micracantha, and Erythrotrichum clades. These groups have convergent morphological characteristics that have challenged taxonomists, making classification difficult. Results from our study delimit 14 clades within the spiny solanums, including the newly designated Asterophorum, Gardneri, Sisymbriifolium, and Thomasiifolium clades. We also establish the placement of species not previously sampled, especially those endemic to Brazil. These results give an increased understanding of the evolution of the Leptostemonum clade by defining monophyletic groups within it and identify areas of the phylogenetic tree that remain unresolved and require further taxon sampling.

AbstractDuring the Nomenclature Section of the XVIII International Botanical Congress that took place in Melbourne, Australia, from 18 to 22 July 2011, it was decided to allow English to be used as an alternative language for producing validating descriptions and diagnoses of new taxa of organisms covered by the International Code of Botanical Nomenclature, which is to be renamed the International Code of Nomenclature for algae, fungi, and plants; on and after 1 January 2012 this can be done in English or Latin. Until then, names of new non‐fossil taxa must continue to be provided with a Latin description or diagnosis in order to be validly published.
