Cryptofauna of a glass sponge reef
No full textABSTRACT
Glass sponge reefs are endemic to the continental shelf waters of British Columbia and Alaska where they form complex three-dimensional habitats used by a variety of commercially important fish and invertebrate species. The Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area (HSQCS-MPA) was designated in February 2017 to protect 2410 km2 of reef habitat. Efforts to establish baseline information regarding reef-associated taxa in the new MPA have documented the diversity of megafauna in detail, but little is understood of the cryptic epifauna inhabiting hidden crevices within the reefs, and even less is understood of larval recruitment, the key reproductive process maintaining long-term reef health and stability. We collected specimens of a reef-building glass sponge Farrea occa from the HSQCS-MPA and described the diversity of their epifauna. Four hundred eighty-nine organisms from six phyla were documented, including seventy-two sponges from three classes. We found several glass sponges: known juvenile reef-builders (two Aphrocallistes vastus and two Heterochone calyx); the lyssacine sponge Leucopsacus scoliodocus, previously known in Canadian waters only from Jervis Inlet; and an unidentified dictyonine sponge previously unknown to waters of British Columbia. Also present were the carnivorous sponge Lycopodina occidentalis, 11 Desmacella austini, and a calcareous sponge. The growth stages we observed suggest multiple settlement events by glass sponge larvae between February and early March. Of the 489 invertebrates, 454 were attached to dead sponge skeleton despite live tissue being much more available as substrate. This study highlights trends in recruitment at sponge reefs, explores factors that may affect larval settlement, describes new sponge associations, and provides the first description of the range of macrofauna found on glass sponges, acting as a baseline for continued monitoring of the MPA
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
