A New Species of the Ornamental Catfish Genus Peckoltia (Siluriformes: Loricariidae) from Rio Xingu Basin, Brazilian Amazon

Peckoltia is one of the 26 genera that constitute the Ancistrini. Although Peckoltia has been reviewed recently, its taxonomic status is not fully resolved and not easily distinguished from Hemiancistrus. Neither Peckoltia nor Hemiancistrus have any recognized synapomorphies supporting their monophyly. In this paper we describe a new species of Ancistrini from Rio Xingu drainage, Par State, Brazil, and assign it to Peckoltia based on its deep body, presence of large odontodes on the cheeks, and lack of carenate plates on the body. The new species can be easily distinguished from all its congeners by its dorsal-fin color pattern (presence of dark thin stripes in the interradial membranes parallel to fin rays that fragment into small spots in larger specimens vs. bands, spots, dots, or membranes with a darker coloration in all other species). Peckoltia feldbergae, new species, differs from all its congeners except P. bachi, P. oligospila, and P. sabaji by having dark brown spots on the entire body (vs. presence of dark transversal bars on the body or a uniform color). Peckoltia feldbergae, new species, can be distinguished from P. oligospila and P. sabaji by a smaller postanal length (28.432.4 of SL vs. 34.338.8 and 35.741.0, respectively). The description of this species is part of an effort to improve our knowledge about the remarkable diversity of rapids-dwelling loricariid catfishes that are greatly threatened by the construction of several large hydroelectric dams in Brazilian Amazon, and to provide a scientific name for a species exploited by the international aquarium fish trade. © 2012 by the American Society of Ichthyologists and Herpetologists

Development of a semi-automatic bibliometric system for publications on animal health and welfare: a methodological study

Bibliometrics is a common research instrument for systemic analysis of scientificprogress in many disciplines, including veterinary sciences. However, bibliometricanalyses are generally biased by limited information included in scientific productionsdatabases. The aim of this study is to propose a method for implementing databases onlivestock health and welfare in a bibliometric perspective. By using the detailed classificationof the scientific disciplines and the list of keywords of the CAB Abstracts , querieswere first built to combine 120 descriptors related to animal species and 1680 descriptorsrelated to the given thematics. Then, the extraction was done from the Web of Science .The overall process focused on the research institutes localised in Europe and on publicationswritten in English. To assess the database accuracy, supplementary filters werevalidated and applied to discard non-specific terms and neighbouring topics. Additionalfields for species groups, infectious and non-infectious diseases, welfare components andgeographical regions were incorporated according to thematic terminologies specificallyestablished. The final database contains 57,523 articles published over a 12 years’ period(2003–2014). The developed method, based on the complementary use of both the CABAbstracts and Web of Science , can be a reference to allow an adequate semi-automaticretrieval of relevant publications on livestock health and welfare, which will be of use toimplement bibliometric study to produce a realistic assessment of tendency for drivingscience policy. Interestingly, it can be also a model process to be easily applied toimplement bibliometric studies for any other scientific thematic domain
