Phylogeny of Oweniidae (Polychaeta) based on morphological data and taxonomic revision of Australian fauna
The family Oweniidae Rioja, 1917 is a small group of broadly distributed polychaetes whose relationships and position in the annelid tree are still poorly understood. A comprehensive revision of the group with reconsideration of character homologies and terminology under a phylogenetic framework was needed. We investigated the relationships of members of Oweniidae and other polychaetes by performing maximum parsimony analyses of 18 oweniid species of the five recognized genera to date and members of the families Siboglinidae, Sabellidae, Spionidae, Magelonidae, and Chaetopteridae. Phylogenetic hypotheses confirmed the monophyly of Oweniidae and suggested sister-group relationships with Magelonidae, although weakly supported. Analyses also recovered Oweniaand Myriowenia as monophyletic and allowed recognition of Myrioglobulaas a junior synonym of Myriochele based on the presence of acicular chaetae and the shape of the head. Implied weighting analyses supported these findings and recovered Galathowenia australis as sister group ofMyriochele. The presence of acicular chaetae justifies the consideration of this species as belonging to Myriochele. Nomenclatural changes are proposed for those species previously considered as members ofMyrioglobula, and these are: Myriochele antarcticacomb. nov., Myriochele japonicacomb. nov., Myriochele islandicacomb. nov., Myriochele malmgrenicomb. nov., and Myriochele australiscomb. nov. After analyses and definition of generic diagnostic features, other new combinations include Galathowenia eurystomacomb. nov. and Galathowenia haplosomacomb. nov., previously considered as members of Myriochele. Taxonomic revision of Australian collections revealed the presence ofMyriochele heruensis Gibbs, 1971, which is herein redescribed, and allowed the description of four new species: Galathowenia annae sp. nov.,Galathowenia arafurensissp. nov., Galathowenia quelissp. nov., andMyriochele australiensissp. nov., mostly from the east coast of Australia, in addition to the three recently well-documented species of Owenia. Australian species have
been described, illustrated, and compared in detail with similar taxa. Distribution patterns and ecological notes have also been given. Keys to oweniid genera and Australian species are provided
Inclusive Schools: the power in our hands
Comunicação apresentada no Congresso Internacional Special Education - ISEC "Including the excluded",na Universidade de Manchester, em Julho de 2000.Representing the great challenge of the educational systems, the inclusive school must be our aim for the next millennium. Is this a consensual goal? If so, how do we conceptualise an inclusive school and how can we work for it with the resources we have and manage to develop?
The present work is a result of an action-research study that started by the enquiry (from June/99 to September/99) to the people responsible for management of all the schools ( more precisely 526, from the preschool level to the third cycle - end of compulsory education in Portugal) of the region of Alentejo, (Baixo Alentejo e Alentejo Litoral) and the intervention (planned for February/2000) with a group of teachers based upon the creative resolution of their school problems, towards the building of a school for all, where children, teachers, parents and other agents of the community find a place to grow personally and professionally
To Name but a Few: Descriptions of Five New Species of "Terebellides" (Annelida, Trichobranchidae) From the North East Atlantic
[Abstract] The number of described species of the genus Terebellides Sars, 1835 (Annelida, Trichobranchidae) has greatly increased in the last years, particularly in the North East Atlantic. In this context, this paper deals with several putative species recently delineated by molecular means within a well delimited clade of Terebellides. Species are characterised here by a combination of morphological characters, and a complementary nucleotide diagnostic approach. Three species were identified as the nominal species T. stroemii Sars, 1835, T. bigeniculatus Parapar, Moreira & Helgason, 2011 and T. europaea Lavesque et al., 2019. Five species are described as new: T. bakkeni sp. nov., T. kongsrudi sp. nov., T. norvegica sp. nov., T. ronningae sp. nov. and T. scotica sp. nov. The distinctive morphological characters refer to the branchial shape, absence or presence of papillae on lamellae of anterior margin of branchial dorsal lobes, absence or presence of ciliated papillae dorsal to thoracic notopodia, geniculate chaetae in one or two chaetigers, and the morphology of thoracic and abdominal uncini teeth. Furthermore, the description of T. bigeniculatus is revised and complemented after examination of type specimens. An updated identification key to all species of the genus in NE Atlantic and a proposal of a classification of different types of abdominal uncini to be used in taxonomy are also included.Agencia Estatal de Investigación; PGC2018–095851–B–C64Ministerio de Economía, Industria y Competitividad; RYC-2016-20799Agencia Estatal de Investigación; RYC-2016-20799Govern de les Illes Balears; RYC-2016-20799Norwegian Biodiversity Information Centre; 70184228Norwegian Biodiversity Information Centre; 70184227Norwegian Biodiversity Information Centre; 7018421
Topology of a percolating soil pore network.
A connectivity function defined by the 3D-Euler number, is a topological indicator and can be related to hydraulic properties (Vogel and Roth, 2001). This study aims to develop connectivity Euler indexes as indicators of the ability of soils for fluid percolation. The starting point was a 3D grey image acquired by X-ray computed tomography of a soil at bulk density of 1.2 mg cm-3. This image was used in the simulation of 40000 particles following a directed random walk algorithms with 7 binarization thresholds. These data consisted of 7 files containing the simulated end points of the 40000 random walks, obtained in Ruiz-Ramos et al. (2010). MATLAB software was used for computing the frequency matrix of the number of particles arriving at every end point of the random walks and their 3D representation
Systematic re-structure and new species of Sphaerodoridae (Annelida) after morphological revision and molecular phylogenetic analyses of the North East Atlantic fauna
[Abstract] Detailed morphological study of more than 2600 North East Atlantic (NEA) sphaerodorids (Sphaerodoridae Annelida) and phylogenetic analyses of DNA sequences of representatives of several identified morphospecies enforced changing the current systematic classification within the family allowed the discovery of new species provided new information about the morphological and genetic characterisation of members of this group and increased the species occurrence data to better infer their geographic and bathymetric distribution ranges. Phylogenetic analyses of nuclear (18S rRNA and 28S rRNA) and mitochondrial sequences (COI and 16S rRNA) of NEA short-bodied sphaerodorids revealed outstanding results including paraphyly of the genera Sphaerodoropsis Sphaerodoridium, and Sphaerephesia. The number of longitudinal and transverse rows of dorsal macrotubercles is proposed as potential synapomorphies for the main clades and are consequently herein used for the genera delimitation. The new classification proposed here implies nomenclatural changes and the erection of a new genus Geminofilum gen. n. to accommodate the species previously considered as Sphaerodoropsis with two transverse rows of dorsal macrotubercles per segment. Four species are being described herein: Euritmia nordica Capa & Bakken sp. n. Sphaerephesia multichaeta Capa Moreira & Parapar sp. n. Sphaerephesia ponsi Capa Parapar & Moreira sp. n. and Sphaerodoridium celiae Moreira Capa & Parapar sp. n. Characterisation of the other 21 species including updated iconography and an identification key to all NEA short-bodied sphaerodorids are provided.This study would have been unfeasible without the access to the material hosted by different institutions and the colleagues who collected, processed, and curated those samples.

Transcriptome Sequencing of Peripheral Blood Mononuclear Cells from Elite Controller-Long Term Non Progressors
The elite controller (EC)-long term non-progressor (LTNP) phenotype represent a spontaneous and advantageous model of HIV-1 control in the absence of therapy. The transcriptome of peripheral blood mononuclear cells (PBMCs) collected from EC-LTNPs was sequenced by RNA-Seq and compared with the transcriptomes from other phenotypes of disease progression. The transcript abundance estimation combined with the use of supervised classification algorithms allowed the selection of 20 genes and pseudogenes, mainly involved in interferon-regulated antiviral mechanisms and cell machineries of transcription and translation, as the best predictive genes of disease progression. Differential expression analyses between phenotypes showed an altered calcium homeostasis in EC-LTNPs evidenced by the upregulation of several membrane receptors implicated in calcium-signaling cascades and intracellular calcium-mobilization and by the overrepresentation of NFAT1/Elk-1-binding sites in the promoters of the genes differentially expressed in these individuals. A coordinated upregulation of host genes associated with HIV-1 reverse transcription and viral transcription was also observed in EC-LTNPs -i.e. p21/CDKN1A, TNF, IER3 and GADD45B. We also found an upregulation of ANKRD54 in EC-LTNPs and viremic LTNPs in comparison with typical progressors and a clear alteration of type-I interferon signaling as a consequence of viremia in typical progressors before and after receiving antiretroviral therapy.We want to particularly acknowledge the patients in this study for their participation and to the HIV BioBank integrated in the Spanish AIDS Research Network and collaborating Centres (http://hivhgmbiobank.com/donor-area/hospitals-and-centres-transferring-samples/?lang = en) for the generous gifts of clinical samples used in this work.

A mega-cryptic species complex hidden among one of the most common annelids in the North East Atlantic
[Abstract] We investigate mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) genetic structure of North East Atlantic lineages of Terebellides, a genus of sedentary annelids mainly inhabiting continental shelf and slope sediments. We demonstrate the presence of more than 25 species of which only seven are formally described. Species boundaries are determined with molecular data using a broad range of analytical methods. Many of the new species are common and wide spread, and the majority of the species are found in sympatry with several other species in the complex. Being one of the most regularly encountered annelid taxa in the North East Atlantic, it is more likely to find an undescribed species of Terebellides than a described one.Funding: Financial support was provided by the Norwegian Taxonomy Initiative [http://www.biodiversity.no/Pages/135523] to AN (Cryptic polychaete species in Norwegian waters, knr 49-13, pnr 70184228), to EO, TB and JAK (Polychaetes in Skagerrak, knr 53-09, pnr 70184216), to TB, EO and JAK (Polychaetes in the Norwegian Sea, knr 55-12, pnr 70184227); and by the Swedish Taxonomy Initiative [https://www.artdatabanken.se/en/the-swedish-taxonomy-initiative/] (Polychaete species complexes in Swedish waters, dnr 140/07 1.4 and 166/08 1.4), and Kungliga Fysiografiska sällskapet Nilsson-Ehle donationerna [https://www.fysiografen.se/sv/] to AN; and by the ForBio Research School funded by the Research Council of Norway [https://www.forskningsradet.no/en/Home_page/1177315753906] (project no. 248799) and the Norwegian Taxonomy Initiative (pnr 70184215) and the Ramon y Cajal program (RYC-2016-20799) funded by Spanish Ministerio de Economía, Industria y Competitividad, Agencia Estatal de Investigación, Comunidad Autónoma de las Islas Baleares and the European Social Fund to MC; and by Akvaplan Niva [http://www.akvaplan.niva.no/en/] to AS and JP.
