Peyssonnelia rosa-marina Boudouresque & Denizot 1973
No full textPeyssonnelia rosa-marina Boudouresque & Denizot, 1973 (Fig. 9): an unsuspected Mediterranean rose garden It is perhaps one of the most abundant seaweeds in the Mediterranean Sea, since it thrives from the infralittoral to the widely extended and widespread coastal detritic bottoms, in the circalittoral, where it is often dominant. It is also a particularly elegant macrophyte, resembling a calcified rosebud, hence its name, Peyssonnelia rosa-marina. Like many red algae, this seaweed can live in rather low irradiance down to ca. 100 m depth; it is an important producer of carbonate sediment and is furthermore an ecosystem engineer that takes a significant part in the construction of the coralligenous beds so characteristic of the Mediterranean. Yet, it has long been confused with its sister species, Peyssonnelia polymorpha, until the 1970s. It was then very surprising to realize that such an abundant, conspicuous, and well-characterized species, both by its morphology and anatomy, had been overlooked for so long.Published as part of Boury-Esnault, Nicole, Bellan, Gerard, Bellan-Santini, Denise, Boudouresque, Charles-Francois, Chevaldonné, Pierre, Dias, Alrick, Faget, Daniel, Harmelin, Jean-Georges, Harmelin-Vivien, Mireille, Lejeusne, Christophe, Perez, Thierry, Vacelet, Jean & Verlaque, Marc, 2023, The Station Marine d'Endoume, Marseille: 150 years of natural history, pp. 213-252 in Zootaxa 5249 (2) on page 236, DOI: 10.11646/zootaxa.5249.2.3, http://zenodo.org/record/768725
Schizoretepora hassi Harmelin, Bitar & Zibrowius 2007
No full textSchizoretepora hassi Harmelin, Bitar & Zibrowius, 2007 (Fig. 13): a mysterious bryozoan from the East Schizoretepora hassi is a cheilostomate bryozoan belonging to the Phidoloporidae, i.e. the family of the beautiful reteporid Reteporella grimaldii (Jullien, 1903), the so-called “lace coral” well-known of Mediterranean divers and which has been the first bryozoan in the world to be illustrated in the literature, by Rondelet in 1554. Among the bryozoans described from the material collected during surveys of the Station Marine d’Endoume, S. hassi is not the most spectacular and its features are only but typical of the family. It lives in shaded rocky habitats of the Lebanese littoral zone and has not yet been found anywhere else. What is surprising is that a Mediterranean species living in the shallow coastal zone with large, conspicuous colonies, had not been described before. The question of its status, steno-endemic of the Levantine Basin or Erythraean immigrant introduced in the Mediterranean, remains open. It was dedicated to Dr Hans Hass, Austrian biologist who was both a famous diving icon and a pioneer in scientific diving and underwater photography. In 1948, he also had written a thesis on the Mediterranean reteporids, collected by diving.Published as part of Boury-Esnault, Nicole, Bellan, Gerard, Bellan-Santini, Denise, Boudouresque, Charles-Francois, Chevaldonné, Pierre, Dias, Alrick, Faget, Daniel, Harmelin, Jean-Georges, Harmelin-Vivien, Mireille, Lejeusne, Christophe, Perez, Thierry, Vacelet, Jean & Verlaque, Marc, 2023, The Station Marine d'Endoume, Marseille: 150 years of natural history, pp. 213-252 in Zootaxa 5249 (2) on page 240, DOI: 10.11646/zootaxa.5249.2.3, http://zenodo.org/record/768725
Paracheilinus hemitaeniatus Randall & Harmelin-Vivien 1977
No full textParacheilinus hemitaeniatus Randall & Harmelin-Vivien, 1977 (Fig. 10): the half-banded flasherwrasse of mesophotic habitats off Madagascar Paracheilinus hemitaeniatus is a rare brightly colored fish species sampled for the first time in 1972, at 45 m depth on the outer slope of the barrier-reef off Toliara, SW Madagascar. Created in 1961 as a branch of the SME, the marine station of Toliara (Tuléar) hosted many scientists who studied the coral reef communities and described a number of new species of marine organisms, contributing largely to improve our knowledge on coral reef diversity. The half-banded flasherwrasse is known only from the south-west of the Indian Ocean, Madagascar and Comoro Islands, where this elusive and beautiful species remains a ‘holy grail’ for photographers. It belongs to the Labridae, a highly diversified fish family, where sexual dimorphism is so pronounced that males, females and juveniles have often been described as separate species by early ichthyologists! Such color dimorphism is viewed as an adaptation to sexual selection and life in coral reefs, where it is more conspicuous than in other environments. Labrids play an important role in the trophic functioning of coral reefs due to their high abundance and diverse feeding behaviors, from small zooplanktivores, crustacean and mollusk feeders to large-sized piscivores. P. hemitaeniatus is a small (<12 cm) species feeding mainly on tiny planktonic crustaceans and participating with other species to the carbon transfer from the water column to mesophotic coral reef habitats.Published as part of Boury-Esnault, Nicole, Bellan, Gerard, Bellan-Santini, Denise, Boudouresque, Charles-Francois, Chevaldonné, Pierre, Dias, Alrick, Faget, Daniel, Harmelin, Jean-Georges, Harmelin-Vivien, Mireille, Lejeusne, Christophe, Perez, Thierry, Vacelet, Jean & Verlaque, Marc, 2023, The Station Marine d'Endoume, Marseille: 150 years of natural history, pp. 213-252 in Zootaxa 5249 (2) on page 238, DOI: 10.11646/zootaxa.5249.2.3, http://zenodo.org/record/768725
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

Variations on the Author
Get PDF“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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
