Material examined Holotype CABO VERDE • 12.7 mm; Sal Island, Rabo de Junco, extreme north of Baía de Murdeira; E. Rolán leg.; MNCN 15.05/1099 (Fig. 4A). Other material CABO VERDE • 1 spec.; Sal Island, Rabo de Junco; 16º41ʹ44ʺ N, 24º58ʹ35ʺ W; 6 Apr. 2014; MNCN exped.; GenBank mitochondrion, partial genome: MF491573; MNCN 15.05/79744. Geographical distribution Only known from the type locality at Sal Island, Cabo Verde Archipelago. Conservation status in IUCN Red List Vulnerable. Remarks This small-sized species endemic to Sal Island is closely related to A. cuneolus. Its distinctive shell and radular morphology as well as the phylogenetic data are consistent with its status as a valid species with a very reduced distribution range.Published as part of Tenorio, Manuel J., Abalde, Samuel, Pardos-Blas, José R. & Cmim, Rafael Zardoya Departamento, 2020, Taxonomic revision of West African cone snails (Gastropoda: Conidae) based upon mitogenomic studies: implications for conservation, pp. 1-89 in European Journal of Taxonomy 663 on pages 23-24, DOI: 10.5852/ejt.2020.663, http://zenodo.org/record/389044
Africonus espingueirensis Cossignani & Fiadeiro 2017
No full textAfriconus espingueirensis Cossignani & Fiadeiro, 2017 Fig. 3P Africonus espingueirensis Cossignani & Fiadeiro, 2017a: 30. Material examined Holotype CABO VERDE • 9.7 mm; Boa Vista Island, Espingueira; MMM (Fig. 3P). Geographical distribution Only known from the type locality. Conservation status in IUCN Red List Not evaluated. Remarks This species has not been examined molecularly. It is morphologically similar to A. antoniaensis, but smaller sized. Radular examination (E. Rolán, pers. com. to MJT) indicated a fully-developed, mature tooth for such a small-sized shell, consistent with that of an adult individual. This observation rules out the possibility of this taxon being a juvenile of another species. We hereby consider it as provisionally valid, pending confirmation by molecular studies.Published as part of Tenorio, Manuel J., Abalde, Samuel, Pardos-Blas, José R. & Cmim, Rafael Zardoya Departamento, 2020, Taxonomic revision of West African cone snails (Gastropoda: Conidae) based upon mitogenomic studies: implications for conservation, pp. 1-89 in European Journal of Taxonomy 663 on page 23, DOI: 10.5852/ejt.2020.663, http://zenodo.org/record/389044

Conus cuneolus form K (not C. cuneolus Reeve, 1843) – Röckel et al. 1980a: 111, pl. 6, row 3. Material examined Holotype CABO VERDE • 21.0 mm; Santo Antão Island, Porto Novo; 17º01ʹ2ʺ N, 25º03ʹ37ʺ W; 2–4 m depth; E. Rolán leg.; MNCN 15.05/47052. Other material CABO VERDE • 1 spec., 14.5 mm; Santo Antão Island, Porto Novo; 17º01ʹ4ʺ N, 25º03ʹ22ʺ W; 15 Apr. 2016; MNCN exped.; GenBank mitochondrion, partial genome: MF491604; MNCN 15.05/78598 (Fig. 4B). Geographical distribution South coast of Santo Antão Island, Cabo Verde Archipelago. Conservation status in IUCN Red List Endangered. Remarks Prior to its introduction as a full species, it was referred to as Conus cuneolus form K in Röckel et al. (1980a). Molecular data clearly confirm that it is a valid species endemic to Santo Antão Island, where it lives in the vicinity of Porto Novo harbor in rocky areas. In the tree, it is recovered as sister to A. curralensis and A. insulae sp. nov. from Santa Luzia Island.Published as part of Tenorio, Manuel J., Abalde, Samuel, Pardos-Blas, José R. & Cmim, Rafael Zardoya Departamento, 2020, Taxonomic revision of West African cone snails (Gastropoda: Conidae) based upon mitogenomic studies: implications for conservation, pp. 1-89 in European Journal of Taxonomy 663 on page 24, DOI: 10.5852/ejt.2020.663, http://zenodo.org/record/389044

Material examined Holotype CABO VERDE • 20.8 mm; Maio Island, Baía de Pau Seco; 1–2 m depth; E. Rolán leg.; MNCN 15.05/1095 (Fig. 4I). Other material CABO VERDE • 1 spec.; Maio Island, Ponta de Pau Seco; 15º15ʹ26ʺ N, 23º13ʹ17ʺ W; 29 Mar. 2013; MNCN exped.; GenBank mitochondrion, partial genome: KY864967; MNCN 15.05/78650. Geographical distribution Maio Island, Cabo Verde Archipelago. Conservation status in IUCN Red List Least concern. Remarks This is a species widely distributed around Maio Island, very especially along the east and north coasts. It is sister to A. roeckeli from Boa Vista Island, and only distantly related to other species with similarities in shell morphology such as A. antoniomonteiroi from Sal Island.Published as part of Tenorio, Manuel J., Abalde, Samuel, Pardos-Blas, José R. & Cmim, Rafael Zardoya Departamento, 2020, Taxonomic revision of West African cone snails (Gastropoda: Conidae) based upon mitogenomic studies: implications for conservation, pp. 1-89 in European Journal of Taxonomy 663 on page 30, DOI: 10.5852/ejt.2020.663, http://zenodo.org/record/389044

Material examined Holotype CABO VERDE • 18.9 mm; Santa Luzia Island, Curral; E. Rolán leg.; MNCN 15.05/1098 (Fig. 3 C). Paratype CABO VERDE • 1 spec.; Santa Luzia Island, Curral; E. Rolán leg.; MJT. Geographical distribution Santa Luzia (Curral) and São Vicente (Saragaça), Cabo Verde Archipelago. Conservation status in IUCN Red List Data deficient. Remarks No specimens of this species have been molecularly examined. Very few specimens have surfaced in the last 30 years, and most of them have been collected as empty shells. Clearly, more studies are needed in order to confirm the status of this taxon. Given the fact that most of the species described from the islands of São Vicente and Santa Luzia have shown relative large genetic divergences, we provisionally consider this as a valid species.Published as part of Tenorio, Manuel J., Abalde, Samuel, Pardos-Blas, José R. & Cmim, Rafael Zardoya Departamento, 2020, Taxonomic revision of West African cone snails (Gastropoda: Conidae) based upon mitogenomic studies: implications for conservation, pp. 1-89 in European Journal of Taxonomy 663 on page 11, DOI: 10.5852/ejt.2020.663, http://zenodo.org/record/389044
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
MATEdb: a new phylogenomic-driven database for Metazoa
No full textInternational audienceThe development (and standardization) of high-throughput sequencing techniques has revolutionized evolutionary biology, to the point that we almost see as normal fine-detail studies of genome architecture evolution (Robert et al., 2022), adaptation to new habitats (Rahi et al., 2019), or the development of key evolutionary novelties (Hilgers et al., 2018), to name three examples. One of thefields that has benefited the most is phylogenomics, i.e. the use of genome-wide data for inferring the evolutionary relationships among organisms. Dealing with such amount of data, however, has come with important analytical and computational challenges. Likewise, although the steady generation of genomic data from virtually any organism opens exciting opportunities for comparative analyses, it also creates a sort of “information fog”, where it is hard to find the most appropriate and/or the higher quality data. I have personally experienced this not so long ago, when I had to spend several weeks selecting the most complete transcriptomes from several phyla, moving back and forth between the NCBI SRA repository and the relevant literatur
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
