Darwinella Muller 1865
No full textGenus <i>Darwinella</i> Müller, 1865 Type species <p> <i>Darwinella muelleri</i> (Schultze, 1865).</p> Emended diagnosis <p> In the <i>Darwinella</i>, the dendritic fibre skeleton is supplemented by fibrous spicules which can be diactinal, triactinal or polyactinal. There is no sand in the fibres but dispersed cellular elements can occur. The sponges are fleshy, encrusting, or massive to lobate; to which fibrous spicule with style shape may be added (emended from Müller 1865).</p> Remarks <p> The species of <i>Darwinella</i> may be confused with those belonging to the genus <i>Aplysilla</i> Schulze, 1878 because of the similarity in external shape; however, <i>Darwinella</i> is characterized by the presence of diactinal, triactinal or polyactinal fibrous spicules (Pronzato 1975). In the present study we described a new fibrous spicule type for the <i>Darwinella</i> genus.</p>Published as part of <i>Bertolino, Marco, Costa, Gabriele, Bavestrello, Giorgio, Pansini, Maurizio & Daneri, Giovanni, 2020, New sponge species from Seno Magdalena, Puyuhuapi Fjord and Jacaf Canal (Chile), pp. 1-49 in European Journal of Taxonomy 715</i> on page 38, DOI: 10.5852/ejt.2020.715, <a href="http://zenodo.org/record/4022397">http://zenodo.org/record/4022397</a>
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
