Leviapseudes Sieg 1983
No full textGenus Leviapseudes Sieg, 1983 Diagnosis (amended after Larsen 2012) Female Rostrum present. Cephalothorax with spiniform processes on branchial chambers. Pereonites with lateral processes. Pereonite 6 longer than wide. Pleonites narrower than pereonite 6. Cheliped carpus as long as or longer than fixed finger. Pereopod 1 merus longer than carpus. Pereopod 4 dactylus/unguis sometimes reduced to a claw. Male As female, but pereonite 6 with clearly identifiable genital cone. Antennule after terminal molt with numerous aesthetascs. Pereopod 4 dactylus/unguis, if reduced to a claw, less evident than in female. Pleonites always with lateral epimera, and epimera larger than in female. Remarks The most recent diagnosis of Leviapseudes, provided by Larsen (2012), included a bi-articulated pleopod exopod, when present, as a distinguishing character. However, a number of species within the genus present a pleopod endopod with one article, namely: L. aberrans (Lang, 1968), L. angelikae, L. demerarae Bacescu, 1984 and L. longissimus Bacescu, 1982. Therefore, we amend the diagnosis deleting this character. The presence of a rostrum (absent in Fageapseudes Bacescu & Gutu, 1971), as well as the presence of spiniform processes on the branchial chambers and presence of lateral processes on the pereonites (verified for all species of Leviapseudes) have been added.Published as part of Gouillieux, Benoit, Labrune, Céline & Esquete, Patricia, 2023, Leviapseudes tethys (Tanaidacea: Apseudidae), a new species from a submarine canyon of the French Mediterranean Sea, with remarks and a diagnosis for the genus, pp. 24-37 in European Journal of Taxonomy 879 on page 27, DOI: 10.5852/ejt.2023.879.2157, http://zenodo.org/record/813545
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
New records of benthic amphipods, Jassa slatteryi Conlan, 1990 and Ampithoe valida Smith, 1873 (Crustacea: Peracarida: Amphipoda) for the Bay of Biscay, France, with morphological notes
No full textInternational audienceJassa slatteryi and Ampithoe valida were collected in the Bay of Biscay. Jassa slatteryi, a cosmopolitan species, was signalized before in European waters, in the Mediterranean Sea and in Brittany. Specimens collected in Arcachon Bay represent the second signalization on the European Atlantic coast. Ampithoe valida, a non-native species originally described in North America, was signalised in European waters before, in the Mediterranean Sea, Portugal and the Netherlands. Its presence in Arcachon Bay and Hossegor Lake is a first record on the French Atlantic coast for this species.Nouveaux signalements d'amphipodes benthiques, Jassa slatteryi Conlan, 1990 et Ampithoe valida Smith, 1873 (Crustacea : Peracarida : Amphipoda) du Golfe de Gascogne, France, et notes sur leur morphologie. Jassa slatteryi et Ampithoe valida ont été collectées dans le Golfe de Gascogne. Jassa slatteryi, une espèce cosmopolite, était signalée dans les eaux européennes en Mer Méditerranée et en Bretagne. Les individus collectés dans le Bassin d'Arcachon représentent le second signalement sur les côtes atlantiques européennes. Ampithoe valida, une espèce invasive originellement décrite en Amérique du Nord, était signalée dans les eaux européennes en Mer Méditerranée, au Portugal et aux Pays-Bas. Sa présence dans le Bassin d'Arcachon et le lac d'Hossegor représente le premier signalement sur la côte atlantique française
