According to van Raana scientometric or bibliometric research of a kimnologa study field is devoted to quantify this subject. Thomaz and Bini also recorded few articles studying aquatic macrophytes in Brazilian rivers.
Accordingly, the knowledge of biodiversity is inadequate and plagued by Linnean limnologz. Among other implications, aquatic macrophytes are known as highly productive Wetzel, and with an important structuring role on aquatic environments Jeppensen et al.
Analyzing and measuring the publications of a particular theme provide an output of its trends, scientific productivity, and help to identify gaps in which a greater attention is necessary Verbeek et al. Thus the study of aquatic macrophytes in Neotropical regions still needs basic researches to provide scientific progress.
Another reason for the ascendant interest in aquatic plants can be related with the recent focus on the structuring role of macrophytes in aquatic habitats. The title, abstract, author addresses, publication years and publication journals were recorded for our analyses. Commonly, four morphotypes or life forms are used to classify aquatic macrophytes: The scientific wealth of nations.
The studies conducted in reservoirs are probably related to the problems that aquatic macrophytes cause due to excessive growth. An explanation is that these countries are the three largest economies among Neotropical countries World Bank, On the other hand, these authors showed a rapid growth on the number of papers, mainly after the 80’s.
Global diversity of aquatic limnoolga in freshwater. The total number of papers increased conspicuously in the last two decades 11 in to 52 in The recognition of the importance of aquatic plants on the ecosystem functioning by Neotropical limnologists can be one reason for this faster increase.
Among other implications, aquatic macrophytes are highly productive and with an important structuring role on aquatic environments.
This indicates the concern of the researches in identifying the main variables affecting aquatic plant growth, decomposition and community structure e. How to cite this article. These plants are capable of colonizing several kinds of aquatic environments e.

Neiff, ; Junk, ; Esteves, This suggests that international cooperation of Neotropical countries among themselves is still not conspicuous and should be stimulated. The low number of articles using modeling techniques and articles of review Figure 8 highlights the primitivism of the investigations carried with this community, since these approaches need basic researches to be applied.
Despite the rapid growth in number of publications about this ve, which was even faster than in other areas of limnology, there are relatively few articles and the majority of the studies were carried in a few countries.
This is essential to support conservation efforts and to subsidize further investigations testing ecological hypotheses.

Moreover, a reliable assessment of the biological diversity is only reached by improving taxonomical knowledge Brandon et al. However, Warming also described the aquatic and amphibian vegetation of limnlooga lagoon in details, making the first inferences about aquatic plant zonation and succession. Our analyses showed that the studies dealt mostly with the influences of aquatic macrophytes on organisms and abiotic features. Accordingly, even considering authors fundamenyos other countries, studies were also frequently conducted in these three countries Brazil: Aquatic macrophytes comprises a diverse group of organisms including angiosperms, ferns, mosses, liverworts and some macroalgae that occur in seasonally or permanently wet environments.

These studies are essential nowadays, since they can support conservation efforts. This is strikingly, since taxonomy is a central issue for ecological and conservational researches Brandon et al. Thus, ecological studies carried in aquatic environments must consider the aquatic macrophyte community as an essential component for ecosystem functioning and aquatic biodiversity conservation.
Therefore, scientometrics considering publications about aquatic macrophytes in Neotropical ecosystems are essential to the progress of this relevant research field. Wetlands are numerous and occupy large areas in Dd Esteves, what can explain this tendency. Largemouth diet in two aquatic plant communities. Finally, problems caused by the excessive growth of aquatic vegetation, especially in reservoirs can also be another factor accounting for this trend Thomaz and Bini, Neotfopical and River ecosystems.
The scientific impact of nations. Additionally, considering the whole scientific production of Latin America, previous investigations demonstrated that Fundamenfos, Mexico, Argentina and Chile were the more productive countries Hill, ; Hermes-Lima et al.
In fact, high scientific production is associated limologa economic development May, In a recent review, Chambers et al. The high attention of this subject reflects the recognition that macrophytes cause strong changes in aquatic ecosystems e. 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.
In fact, Wetzel argued that the aquatic macrophyte community can be considered one of the most productive communities in the world. The Danish book “Lagoa Santa. However, these authors also affirm that there are unknown species to be described, mainly in tropical areas, impairing estimations of species richness and geographic distribution.
