Acacia hydaspica J.R.Drumm. ex R.Parker (1921: 309) and A. pseudoeburnea J.R.Drumm. ex Dunn (1922: 185) were treated as conspecific with A. eburnea (L. f.) Willd. (1806: 1081) by Chakrabarty & Gangopadhyay (1996: 609). However, when these taxa were recently transferred to Vachellia they were treated as distinct species, namely, V. hydaspica (J.R.Drumm ex R.Parker) Ali (Jan. 2014: 3; this same combination was also made by Ragupathy et. al. in March 2014: 176), V. pseudoeburnea (J.R.Drumm. ex Dunn) Ragupathy et al. (2014: 177) and V. eburnea (L.f.) Hurter & Mabberley in Mabberley (2008: 1021), respectively. Neither Ali (l.c.) nor Ragupathy et al. (l.c.) provided distinctive features of the taxa to justify their adoption of species rank, although Ragupathy et al. (l.c.) did say that they were following the classification of Kumar & Sane (2003) and Roskov et al. (2005) rather than that of Chakrabarty & Gangopadhyay (1996). The present studies for the ‘Flora of India Project’ currently in preparation revealed that the dividing lines between Vachellia eburnea, V. hydaspica and V. pseudoeburnea are not clear cut (Table 1) and therefore they are best treated as a single species, V. eburnea. The necessary synonymy (and typification) is therefore made here.

ABSTRACT: Rhipicephalus ( Boophilus) species are monoxenous ticks with seasonal distribution in tropical and subtropical regions. For many years, Rhipicephalus micropluswas considered as a single species; however, further analysis split these ticks into two distinct species. Because R. microplusand R. australisshare similar attributes, it is hard to discriminate these two species and explain the changes in the classification of these parasites over the past decades. The reappearance of R. australisis an outcome of new research, which has afforded to better characterize these probably cryptic species. Evidence based on morphological features, the lack of conspecificity, microsatellite markers, mitochondrial 12S and 16S ribosomal DNA, and mitochondrial genome supports the re-classification of R. microplusas different species. Therefore, populations of R. microplusfrom Australia, Cambodia, Philippines, Indonesia, New Caledonia, Borneo, New Guinea, Tahiti and parts of Southeast Asia were recently reinstated as R. australis. Moreover, a better knowledge on the speciation between these two species could pave the way to important advances in tick control strategies.

The morphology of the genus Chaetoceros, one of the most abundant and diverse planktonic diatom groups, was investigated using material collected in the eastern Adriatic Sea from 2006 to 2012. Twenty-seven morphologically distinct species have been identified from both field samples and cultivated strains. Two species, C. bacteriastroides and C. pseudodichaeta, are reported for the first time for the area. Morphometric data, general morphology and ultrastructural characters are presented for each species, based on light and electron microscopy observations, with a special emphasis on species-specific distinctive features. Valve ultrastructure appeared to be characteristic for single species or group of closely related species, especially inside the subgenus Hyalochaete. A collection of appropriate micrographs will facilitate future identification of Chaetoceros species and morphological comparison with material from other geographic areas.

AbstractLichen thalli provide a long-lived and stable habitat for colonization by a wide range of microorganisms. Increased interest in these lichen-associated microbial communities has revealed an impressive diversity of fungi, including several novel lineages which still await formal taxonomic recognition. Among these, members of the Eurotiomycetes and Dothideomycetes usually occur asymptomatically in the lichen thalli, even if they share ancestry with fungi that may be parasitic on their host. Mycelia of the isolates are characterized by melanized cell walls and the fungi display exclusively asexual propagation. Their taxonomic placement requires, therefore, the use of DNA sequence data. Here, we consider recently published sequence data from lichen-associated fungi and characterize and formally describe two new, individually monophyletic lineages at family, genus, and species levels. The Pleostigmataceae fam. nov. and Melanina gen. nov. both comprise rock-inhabiting fungi that associate with epilithic, crust-forming lichens in subalpine habitats. The phylogenetic placement and the monophyly of Pleostigmataceae lack statistical support, but the family was resolved as sister to the order Verrucariales. This family comprises the species Pleostigma alpinum sp. nov., P. frigidum sp. nov., P. jungermannicola, and P. lichenophilum sp. nov. The placement of the genus Melanina is supported as a lineage within the Chaetothyriales. To date, this genus comprises the single species M. gunde-cimermaniae sp. nov. and forms a sister group to a large lineage including Herpotrichiellaceae, Chaetothyriaceae, Cyphellophoraceae, and Trichomeriaceae. The new phylogenetic analysis of the subclass Chaetothyiomycetidae provides new insight into genus and family level delimitation and classification of this ecologically diverse group of fungi.

Abstract This article provides a quantitative and qualitative analysis of the translation of English drama film titles into Peninsular Spanish, drawing on cognitive modelling and following preliminary findings in Peña-Cervel (2016). Our study is consistent with the epistemological and ontological grounding of Cognitive Linguistics (Samaniego-Fernández 2007) and contributes to satisfying one of the major challenges Rojo-López and Ibarretxe-Antuñano (2013a, 10) identify for present-day Translation Studies: To reveal the conceptual substratum that guides the translation process. Our approach does not rely on an exhaustive classification of clear-cut and well-defined translation techniques, but rather on a broad distinction between direct and oblique strategies. We demonstrate how the notion of cognitive operation, as proposed by Ruiz de Mendoza-Ibáñez and Galera-Masegosa (2014), can help elucidate the sometimes seemingly arbitrary relationship between original English titles and their counterparts in Spanish, especially in cases of traditionally so-called free translations. Stands-for relations, such as expansion and reduction, are shown to play a fundamental role in the translation process and the fruitful combination of cognitive operations into conceptual complexes is explored. Our study attempts to go beyond descriptive adequacy in order to achieve explanatory adequacy.

ABSTRACTA classification and nomenclature scheme has been approved by the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification for the minerals of the graftonite group. The crystal structures of these minerals have three distinct sites that are occupied by Fe2+, Mn2+and Ca2+. These sites have coordination numbers [8], [5] and [6], and these differences lead to very strong order of Fe2+, Mn2+and Ca2+over these sites. As a result of this strong order, the following compositions have been identified as distinct species: graftonite: FeFe2(PO4)2; graftonite-(Ca): CaFe2(PO4)2; graftonite-(Mn): MnFe2(PO4)2; beusite: MnMn2(PO4)2; and beusite-(Ca): CaMn2(PO4)2.

Counterfeit note has a disastrous impact on a country’s economy. The circulation of such fake notes not only diminishes the value of genuine note but also results in inflation. The feasible solution to this burning issue is to create awareness about the counterfeit notes among public and to equip them with a technology to detect fake notes on their own. Though there exist numerous research articles on detection of fake notes, they are not handy. The reason for this could be the unavailability or unaffordability in acquiring the equipment for the same. This paper proposes an approach whose implementation can easily be deployed on a smart phone and hence anyone with access to them can use the application to detect the fake notes. The proposed approach consists of the processing phases including image procurement, pre-processing, data augmentation, feature extraction and classification. ₹500 notes are considered for experimentation analysis. Out of 17 distinctive features, 3 such from the obverse side are considered to evaluate the genuineness of the note. Siamese neural network is employed to build a model for effective classification of the notes. The performance of the proposed approach is evaluated at 85% with respect to accuracy.

In the present study, morphological and molecular markers (RAPD primers) were used to analyze the genetic diversity and genetic relationships among 21 accessions of Echinochloa spp. complex comprising the wild and cultivated species collected from Melghat and adjoining regions of Vidarbha, Maharashtra. The availability of diverse genetic resources is a prerequisite for genetic improvement of any crop including barnyard millet. A high degree of molecular diversity among the landraces was detected. Among the 21 genotypes, two major groups (A and B) were formed, at 67.28 % similarity, which clearly encompasses 15 accessions of E. frumentacea and 6 accessions of E. colona. Higher similarity was observed in accessions of E. frumentacea. The accessions IC 597322 and IC 597323 also IC 597302 and IC 597304 showed more than 94% similarity among themselves. The classification of genetic diversity has enabled clear-cut grouping of barnyard millet accessions into two morphological races (E. frumentacea and E. colona).

Abstract The well-known Russian ornithologist Prof. Peter Sushkin described it as a distinct species from Bashkortostan (Bashkiria) in 1897, a highly acclaimed discovery. However, its breeding grounds never been discovered. Since then, there has been a long-standing debate over the taxonomic position of Anser neglectus. Taxonomists have argued that Anser neglectus belongs to the group of A. fabalis Lath. because of its close resemblance with A. f. fabalis. At the beginning of the 20th century, large numbers of the Sushkin’s goose were observed in three winter quarters: on two lakes in the Republic of Bachkortostan, in the surroundings of the town of Tashkent in the Republic Uzbekistan, and in the puszta Hortobágy in eastern Hungary. It is a pity that taxonomists did not thoroughly compare the Russian and Hungarian ornithological papers concerning the former presence of Anser neglectus in these areas, because these rich sources refer to characteristics that would cast serious doubt on the classification of Anser neglectus as a subspecies, an individual variation or mutation of A. f. fabalis. Sushkin’s goose, though a typical Taiga Bean Goose, distinguished itself from other taxa of the Bean Goose by its plumage, its field identification, by its specific “Gé-gé” call, the size of its bill, and by its preference for warm and dry winter haunts. A. neglectus should therefore be considered a separate, fully distinct species, sensu Stegmann (1935) and Stegmann in Schenk (1931/34), if we follow the established criteria in bird systematics of Tobias et al. (2010). Between 1908 and 1911, an estimation of up to 150.000 individuals of A. neglectus wintered in the Hortobágy puszta. Approximate counts for both other winter quarters are not available. The last living birds were seen in the zoological garden of Budapest in 1934. Since then, A. f. fabalis and A. s. rossicus “Type neglectus” (i.e. A. f. fabalis and A. s. rossicus with a color of the bill and the legs, similar to the former A. neglectus) have been observed sporadically on the breeding grounds and in the winter quarters of both taxa. However, the true A. neglectus seems to be extinct. Its sudden disappearance may be related to the Tunguska event, the catastrophe in 1908 that may have caused genetic mutations. This hypothesis is considered to be the most likely, among other available hypotheses about its extinction.
