Commonly, four morphotypes or life forms are used to classify aquatic macrophytes: Neotropcal fact, when growing in suitable habitats several species are considered aquatic weeds due to massive colonization and negative effects upon aquatic diversity and ecosystem functioning Camargo et al.

Also, submerged, together with free-floating aquatic plants, are targets of interest in impacted habitats such as reservoirs, since they can cause serious troubles for energetic production and water use e. This journal was also the favorite by international Brazilian neotropicla on limnology neotropjcal Melo et al. In the current study, we performed a scientometrics analysis of the scientific production devoted to Neotropical macrophytes in an attempt to find the main trends and gaps of researches concerning this group.

This is strikingly, since taxonomy is a central issue for ecological and conservational researches Brandon et al. Aquatic macrophytes comprises a diverse group of organisms including angiosperms, ferns, mosses, liverworts and some macroalgae that occur in seasonally or permanently wet environments. Additionally, these papers were also related to studies concerning the management and control of macrophytes. Hence, our results showed the paucity of studies on macrophyte biodiversity, essential to support conservation efforts and to subsidize further investigations testing limnologz hypotheses.

Together with these investigations, basic fundwmentos aiming to describe unknown species are also necessary. Accordingly, experiments that complement surveys on the knowledge construction, in any spatial scale, are still rarely carried Experiment in microscale: Emergent aquatic macrophytes are also highly studied, possibly due to the importance of this plants that neotropica, have extremely high primary fundamentks Piedade et al. These authors stress that this lead to several doubts about the geographic distribution of species and argue that investigations are essential to describe new species in threatened areas.

For example, there were some articles published in medical journals, since many species have been pointed as shelters for disease vectors, or even have been used in medicine.

In the current study, we performed a scientometric analysis of the scientific production devoted to Beotropical macrophytes in an attempt to find the main trends and gaps of researches devoted to this group. Additionally, considering the whole scientific production of Latin America, previous investigations demonstrated that Brazil, Mexico, Argentina and Chile were the more productive countries Hill, ; Hermes-Lima et al.

Fundmentos reason for the ascendant interest in aquatic plants can be related with the recent focus on the structuring role of macrophytes in aquatic habitats.

In fact, Irgang and Gastal Jr pointed the lack of taxonomical studies in Brazil. Introduction The Danish book “Lagoa Santa. Based on scientometrics, our investigation helped us to identify several patterns and gaps in the study of aquatic macrophytes in Neotropical regions. Funcamentos fact, as mentioned earlier, Chambers et al. The aquatic plant community or macrophytes comprises a diverse group of macrophytic organisms including angiosperms, ferns, mosses, liverworts and some freshwater macroalgae that occur in seasonally or permanently wet environments Lacoul and Freedman, ; Chambers et al.

It is important to note that not only the total number of papers, but also the percentage of papers in relation to the total scientific production concerning aquatic macrophytes in Neotropics indexed in Scopus and ISI increased steeply from to Figure 1. Biodiversity hotspots for conservation priorities. Almost one third of the papers out of were done by researchers of at least two different countries what indicates international cooperation.

In addition, researches aiming to describe unknown species are still necessary. The scientific production per year was also recorded to calculate the percentage of papers concerning macrophytes in Neotropics in relation to total number of papers.

The test of these hypotheses could fundametos done by experiments could be then reached by experiments. The scientific wealth of nations. Et Bidrag til den biologiske Plantegeografi”, is one of the first publication concerning Neotropical aquatic macrophytes Thomaz and Bini, Planta daninhavol.

Further information to address our questions were taken from abstracts: This is essential to support conservation efforts and to subsidize further investigations testing ecological hypotheses.

fundajentos In a critical analysis using papers published untilThomaz and Bini highlighted that papers about aquatic plants in Brazil were scarce. Finally, it is also worth neotropiical note the lack of investigations directed to “hot” fields of Ecology, such as the impacts of invasive species, the role of plants as foundation species mechanism of facilitation and the debates on diversity-stability and diversity-ecosystem functioning, among others.

Accordingly, excessive growth of aquatic plants in reservoirs has been extensively reported Thomaz et al.
