Cienciometria dos estudos de invertebrados bentônicos de água doce no Brasil

Abstract

Aim: The aim of this paper is to analyze trends in the literature concerning benthic invertebrates in Brazil, mainly the number of published papers and approaches used. Methods: The Ph.D. database of the Lattes Platform (CNPq) was used as the source of information for the period 1970-2014. We searched for the terms “benthos”, “macroinvertebrates”, and “zoobenthos” in the titles and keywords of the papers listed on the platform. Papers were classified into the following categories: Systematics, Life History, Ecology, and Divulgation. These categories were further divided into subcategories. The percentage of papers in every major category and subcategory was calculated. Results: The search introduced 1,573 papers, which were mainly related to Ecology and Systematics. From 1970 to 2009, the number of papers published per decade increased exponentially, and the upward trend continues. The number of papers concerning Systematics, especially in Taxonomy, is increasing. Of the papers in Ecology category, those about Structure, Dynamics, and Distribution of the fauna have been increasing since the 1980s, and there has been an evident increase in the production of papers related to environmental damage in the last decade. The rate of production of papers concerning the role of invertebrates in ecosystems and the effects of different Spatial Scales has been increasing since the 2000s. Conclusion: There is a clear tendency towards the increased continuity of paper production concerning freshwater benthic invertebrates, and relatively new approaches as Conservation and Exotic Species are becoming relevant.
