AbstractThree species of Plectus Bastian, 1865 viz., P. aquatilis and P. pusillus from Kerman province and P. velox from Alborz province, Iran are described and illustrated. Partial sequences of 18S region of ribosomal DNA gene were amplified for P. aquatilis and P. pusillus. The Blast results of population of P. aquatilis from Iran showed 8–10 nucleotides differences with populations of the same species (AF036602; GQ892827; AY284700) reported from the UK, Belgium and The Netherlands, respectively. Whereas Iranian population of P. pusillus showed 14–16 nucleotides differences with P. cf. pusillus (AY284705; AY284704) reported from The Netherlands. Molecular analysis revealed close relationship of the Iranian plectids with P. cf. parvus (AY284699) reported from The Netherlands. Phylogenetic relationships with other related species in the genus Plectus and closely related genera that are available in the GenBank are given.

The genus Flavivirus, family Flaviviridae, includes a number of important arthropod-transmitted human pathogens such as dengue viruses, West Nile virus, Japanese encephalitis virus and yellow fever virus. In addition, the genus includes flaviviruses without a known vertebrate reservoir, which have been detected only in insects, particularly in mosquitoes, such as cell fusing agent virus, Kamiti River virus, Culex flavivirus, Aedes flavivirus, Quang Binh virus, Nakiwogo virus and Calbertado virus. Reports of the detection of these viruses with no recognized pathogenic role in humans are increasing in mosquitoes collected around the world, particularly in those sampled in entomological surveys targeting pathogenic flaviviruses. The presence of six potential flaviviruses, detected from independent European arbovirus surveys undertaken in the Czech Republic, Italy,Portugal, Spain and the UK between 2007 and 2010, is reported in this work. Whilst the Aedes flaviviruses, detected in Italy from Aedes albopictus mosquitoes, had already been isolated in Japan, the remaining five viruses have not been reported previously: one was detected in Italy, Portugal and Spain from Aedes mosquitoes (particularly from Aedes caspius), one in Portugal and Spain from Culex theileri mosquitoes, one in the Czech Republic and Italy from Aedes vexans, one in the Czech Republic from Aedes vexans and the last in the UK from Aedes cinereus. Phylogenetic analysis confirmed the close relationship of these putative viruses to other insect-only flaviviruses.

A New Species

Summary A new species of Aporcelaimellus, collected in a watermelon field in Nigeria, is described, including its morphological and molecular (D2-D3 28S-rDNA, 18r-DNA) characterisation. Aporcelaimellus nigeriensis sp. n. is distinguishable by its 2.76-3.55 mm length, very coarse ventral body pores, lip region offset by deep constriction and 24-27 μm broad odontostyle 30-36 μm long at its dorsal and 28-31 μm at its ventral side, neck 648-779 μm long, pharyngeal expansion occupying 54-60% of total neck length, uterus 300-473 μm or 2.1-3.2 body diam. long and tripartite, V = 49-54, tail short and convex conoid (27-41 μm, c = 72-115, c′ = 0.5-0.7), spicules 108-137 μm long, and 9-10 spaced ventromedian supplements with hiatus. LSU analysis revealed a close relationship of A. nigeriensis sp. n. with other Aporcelaimellus species and questioned, once more, the monophyly of Aporcelaimidae. SSU phylogenetic tree was not able to resolve the relationship between the new species and other closely related species.

Phylogenetic relationships among species of Bulbophyllum sect. Trias and related taxa in Bulbophyllum has not been previously studied due to scarcity of appropriate samples. In this study, we aimed to assess the relationship of these taxa and investigate interspecific relationships of these orchids using DNA sequences from two plastid genes, rbcL and matK, and one nuclear region, nuclear ribosomal internal transcribed spacer, nrITS. Our results showed that all Bulbophyllum sect. Trias species were embedded among other groups of Bulbophyllum, supporting the already published transfer of Trias to synonymy of Bulbophyllum. All trees revealed that the Indochinese sect. Trias form a monophyletic group that could be divided into three groups coincident with their vegetative characters. This study further shows that nrITS sequences can be sufficient for inferring phylogenetic relationship among Trias species, although this marker and the combination of this plus the plastid genes are not able to distinguish the differences between some closely related species.

During a survey on the soil nematodes from Kerman province, three species of Ironus, i.e., I. andamanus, I. elegans and I. ignavus, were isolated from natural areas in Kerman province (Iran). Descriptions, measurements and illustrations are provided for all three species. Furthermore, sequence data of the 18S rDNA gene are provided for I. andamanus and I. elegans. The Blast search results of I. andamanus showed six nucleotide differences with I. longicaudatus (FJ040495) from The Netherlands. Molecular analysis of I. elegans set this population apart from other species of Ironus, although I. elegans is closer to an undescribed Ironus (FJ040496) from The Netherlands. These are the first data of 18S rDNA for I. andamanus and I. elegans. Phylogenetic relationships with other related species of Ironus and closely related genera available in GenBank are discussed.

Abstract Canada’s trade relations with the UK have been governed by the CETA since the signature of that agreement with the EU in October 2016. Subsequent to the decision of the UK electorate to leave the EU, it became necessary to envisage the creation of a new trade agreement directly between the UK and Canada. Initially, the Government of Canada indicated a willingness to negotiate a new trade agreement with the UK as quickly as possible. But, as the future relationship of the UK to the EU became increasingly uncertain, the Government of Canada decided to hold back until greater clarity could be obtained. As of July 2020, Canada was still waiting. The future trade agreement will reflect the desire of both countries to maintain their long-standing and close relationship. Both have strong interests in trade and investment with the other and both will seek to reinforce these interests. The particular concerns of both countries are outlined in this paper and the outlines of a future trade agreement are set out. In conclusion, the author suggests that it would be in the interests of the UK, rather than seeking simply a bilateral agreement, to seek to negotiate an Atlantic Free Trade Agreement, thereby clarifying its relations not simply with Canada but with all of Europe and North America.

Gondwanan Jurassic non-neosauropod eusauropods are key for the understanding of sauropod evolution, although their phylogenetic interrelationships remain poorly understood. However, following the revision of the holotype of a key taxon from the early Middle Jurassic Cañadón Asfalto Formation Patagonia, Argentina, Patagosaurus fariasi, the phylogenetic a ? nities need to be tested with new osteological information gathered during the redescription of the holotype of Patagosaurus. A new phylogeny presented here shows a close a ? liation of Patagosaurus with Cetiosaurus from the Middle Jurassic of the UK. The close relationship of Patagosaurus with Barapasaurus, often found in previous phylogenies, was not recovered here. Instead, Patagosaurus is retrieved as more derived than most Early and Middle Jurassic sauropods, although more basal to Mamenchisaurus, Omeisaurus, turiasaurians, and neosauropods. Another sauropod taxon found together with Patagosaurus, Volkheimeria, is retrieved several nodes more basal than the former, which shows, together with evidence of several other sauropod taxa in the Cañadón Asfalto Formation, that a high evolutionary diversity existed in Southwest Gondwana in the early Middle Jurassic, a pattern which is also seen in fossil groups other than sauropods (e.g., theropods).

AbstractSpecies of the genus Mizelleus Jain (1957) have always been controversial regarding identification and validity. Members of this group of species differ from each other in the morphology of their hard parts, which can be misleading and subject to differing interpretation among scientists. Therefore, the main objective of present study was to identify Mizelleus worms by morphological methods and molecular analysis on the basis of 18S ribosomal DNA to clarify their phylogenetic status. In this study, specimens were isolated from the gill filaments of Wallago attu (Siluriformes) and studied morphologically. In accordance with morphological characters, the specimens were found to be Mizelleus indicus and Mizelleus longicirrus. Partial sequences of nuclear 18S rDNA of these two species were amplified. The results confirm the phylogenetic relationships and taxonomic validation of M. indicus and M. longicirrus in India.

Case studies in the Netherlands and the UK of asylum applicants excluded or under consideration of exclusion pursuant to Article 1Fa of the Refugee Convention reveal that some applicants falsely implicated themselves in serious crimes or behaviours in order to enhance their refugee claim. This may have serious consequences for the excluded persons themselves, as well as for national governments dealing with them. For this reason we suggest immigration authorities could consider forewarning asylum applicants i.e. before their interview, about the existence, purpose and possible consequences of exclusion on the basis of Article 1F.
