ABSTRACT

Presento la investigación sobre las bases de datos bibliográficas Biosis, CAB, Periódica, SCI, Scopus y Zoological Record. Se estudian características para identificar cuáles y cuántas es necesario utilizar para tener la información más representativa. De 1.363 revistas analizadas, el 36,5% se encuentra en más de una base de datos y el 63,46% se registra solo en una. Zoological Record contiene 63.421 documentos, Biosis 19.079, CAB 14.363, Periódica 11.185, SCI 3.257 y Scopus 916. CAB y ZR son las más antiguas, el promedio de artículos publicados por año para Biosis fue de 6.417, ZR 433, Periódica 361, CAB 145, SCI 91 y Scopus 30. El análisis de redes muestra mayor relación entre Biosis y SCI, que comparten 16% de títulos, CAB y Biosis comparten 15%, Biosis y ZR 14%, y CAB y ZR 11%. Un análisis de parsimonia muestra que Biosis y SCI comparten más revistas y Periódica tiene más revistas exclusivas (285). Periódica publicó el 24,6% de artículos con descripciones de nuevos taxones y un promedio de 90 al año, CAB 54,6% con promedio de 82 y ZR 72,9% con 322. Ninguna de las bases de datos cumple con las características suficientes empleadas como fuente de información única, es conveniente utilizar distintas combinaciones de acuerdo con las necesidades informativas. Biosis tiene la información más exhaustiva sobre cualquier taxón actual, Zoological Record y CAB tienen una cobertura temporal amplia e incluyen principalmente animales o plantas, respectivamente. SCI tiene el mayor número de documentos en revistas de corriente principal, con referencias, citas e indicadores bibliométricos. Periódica cuenta con mayor cantidad de documentos y cobertura temporal más amplia sobre lo publicado en América Latina. El cladograma obtenido por el análisis de parsimonia resultó ser una herramienta de visualización ideal para representar las características principales de las bases de datos.


I compare six bibliographic databases with information on Latin American systematics: Biosis, CAB, Periódica, SCI, Scopus and Zoological Record. The databases are characterized and compared considering their content, temporal, typological, geographical, thematical coverage, kind of access and new taxon description, to identify which and how many should be used to be more representative. Of the 1363 journals analyzed, 36.5% are found in more than one database and 63.46% are recorded in a single one. Zoologial Record contains 63421 documents, Biosis 19079, CAB 14363, Periódica 11185, SCI 3257 and Scopus 916. CAB and ZR are the oldest databases, the average number of articles published per year was 6417 for Biosis, 433 for ZR, 361 for Periódica, 145 for CAB, 91 for SCI and 30 for Scopus. According to the network analysis, there are stronger relations between SCI and Biosis, which share at least 16% of titles, CAB and Biosis share 15%, Biosis and ZR 14%, and CAB and ZR 11%. Based on the cladogram obtained from a parsimony analysis on the shared journals, the strongest relation is between Biosis and SCI; Periódica has the largest number of exclusive journals with 285. ZR has 72.9% of published articles with descriptions of new taxa and an average of 322 a year, CAB 54.6% with 82, and Periódica 24.6% with 90. None of databases meets the characteristics to be used as a single source of information, therefore it would be appropriate to use different combinations according to the aim of the analysis. Biosis has the most comprehensive information on any current taxon, Zoological Record and CAB have a broader temporal coverage and include mainly animals or plants, respectively. SCI has the largest number of documents in mainstream journals, with references, citations and bibliometric indicators. Periódica has the largest number of documents and temporal coverage published in the area. The cladogram proved to be an optimal visualization tool to represent the main features of each data base.

ABSTRACT

Bibliometry of biological systematics in Latin America during the twentieth century in three global databases. We present a review of the biological systematic research in Latin America during the twentieth century, applying a bibliometric analysis to the information contained in international databases with the largest number of biological records: Biosis (since 1969), CAB (since 1910) and Science Citation Index (since 1900), to recognize certain patterns and trends regarding the document production. We obtained 19 079 documents and 1 387 journals for Biosis, 14326 and 2537 for CAB, 3257 and 1636 for SCI. Of the documents, 54.6% related to new species, 15.3% dealt with morphology, 14.9% keys, 12.5% descriptions, 10.6% cases of synonymies, 6% new genera, 4.9% new geographical records, 23.6% geographical distribution, 4.2% redescriptions, and 3.6% with new nomenclatural combinations. The regions mentioned were South America with 11.9%, Central America with 4% and America (all) with 2.56%. Nineteen Latin American countries appear, whereas outside this region we found the United States of America with 12.6% of representation and Canada with 3%. Animals (65.6%) were the most studied taxa, which was 1.7 times higher than what was published for plants (37%), 11 times higher than fungi (6%) and nearly 30 times higher than microorganisms (2.3%). Out of the 155 journals that produced 66% of the papers, 76.5% were better represented in Biosis, 21.4% in CAB and 2% in SCI. Twenty-nine journals published 33% of the articles, the maximum number of records obtained was 69% for Biosis, CAB 24% and 6.9% for SCI, three (10.3%) are in biology, 11 (37.9%) in botany, 13 (44.8%) zoology, and two (6.9%) paleontology; eight of these journals (27.5%) were published in Latin America and twenty were indexed in the Science Citation Index. In the last two years more journals of the region that publish on taxonomy have been indexed, but their impact factor is still low. However, the impact factor of a number of Latin American journals that published biodiversity increased with time. Countries that are more interested in studying the Latin American biota from the taxonomic point of view are Brazil, the United States, Argentina and Mexico. The most active institutions in this discipline were the Universidade de São Paulo, Universidad Nacional Autónoma de México, and the Universidade Federal do Rio de Janeiro; together they produced 24% of the documents.

Aplicamos bibliometría a las bases de datos: Biosis, CAB y Science Citation Index. El 54.6% de los documentos son especies nuevas, 15.3% morfología, 14.9% claves, 12.5% descripciones, 10.6% sinonimias, 6% géneros nuevos, 4.9% registros geográficos nuevos, 23.6% distribución geográfica, 4.2% redescripciones y 3.6 combinaciones nomenclaturales nuevas. Los taxones más estudiados fueron los animales (65.6%), seguidos de las plantas (37%), los hongos (6%) y los microorganismos (2.3%). Veintinueve revistas publicaron el 33% de los artículos, tres (10.3%) son de biología, 11 (37.9%) de botánica, 13 (44.8%) de zoología y dos (6.9%) de paleontología; ocho revistas (27.5%) son editadas en la región y veinte estuvieron indizadas en el SCI. En los últimos dos años se han indizado más revistas editadas en la región que publican sobre taxonomía, pero su factor de impacto sigue siendo bajo respecto al promedio del área. Los países que más se han interesado en estudiar la biota de América Latina desde el punto de vista taxonómico son: Brasil, Estados Unidos, Argentina y México. Las instituciones más activas fueron la Universidade de São Paulo, la Universidad Nacional Autónoma de México y la Universidade Federal do Rio de Janeiro; juntas produjeron el 24% de los documentos.

ABSTRACT

Para tener una visión regional del estado de desarrollo de la sistemática en América Latina durante las últimas tres décadas, se presentan los resultados del análisis cienciométrico de 11185 documentos publicados entre 1976 y 2006 en 411 revistas de la región, obtenidos de la base de datos Periódica. Se describe el estado actual de la disciplina en el área, se exponen análisis detallados sobre los artículos, países, principales líneas de estudios, grupos taxonómicos, temas, formato, tipo de documento, contenido, idioma y se contextualiza la información. La producción especializada sobre sistemática publicada en las revistas locales fue notable y se mantuvo estable a partir de los 80, centrándose principalmente en México, Brasil y Argentina. Los contenidos fueron publicados en español primariamente y en forma de artículos. Versaron especialmente sobre taxonomía descriptiva y se relacionaron con la ecología, anatomía, histología y biología acuática. Los grupos más representados fueron los insectos y las angiospermas. Se concluye haciendo una llamada a la necesidad urgente de sistematizar la literatura de sistemática sobre taxones latinoamericanos.


In order to have a regional vision of the development of systematics in Latin America during the last three decades, the results of a scientometric analysis based on 11185 documents on this theme published in 411 journals from 1976 to 2006 and obtained from the Periodica data base are presented. The current state of the discipline in the region is described, a detailed analysis about the articles, countries, main lines of study, taxonomic groups, topics, format, type of document, content and language is carried out, and the information is contextualized. The specialized production on systematics produced and published in local journals was notable and remained stable after the 80’s, mainly in Mexico, Brazil and Argentina. The contents have been published primarily in Spanish and mainly in the form of articles. They dealt mostly with descriptive taxonomy and were related to ecology, anatomy, histology and aquatic biology. The most represented groups were insects and angiosperms. A call is made for the urgent need of systematizing the literature about Latin American taxa.
