Chemical composition of floating aquatic macrophytes used to treat of aquaculture wastewater. The test of these hypotheses could be done by experiments could be then reached by experiments.

The scientometrics research can be considered the area of research that utilizes information contained in publications to obtain a scientific output of its trends and lacks Verbeek et al. Effects of flooding regime upon the decomposition of Eichhornia azurea Sw. 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. Despite the rapid growth in number of publications about this community, 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.

Accordingly, the knowledge of biodiversity is inadequate and plagued by Linnean i. Largemouth diet in two aquatic plant communities.

Environmental influences on aquatic plants in freshwater ecosystems.

In a recent review, Chambers et al. This observation is shocking in Neotropical regions, since this region contain seven hotspots global priority conservation areas out of the 25 postulated by Myers et al. The analysis was based on abstracts of papers published between and April The study of aquatic macrophytes in Neotropics: Et Bidrag til den biologiske Plantegeografi”, is one of the first publication concerning Neotropical aquatic macrophytes Thomaz and Bini, Nos jardins submersos da Bodoquena: On the other hand, these authors showed a rapid growth on the number of papers, mainly after the 80’s.

This is strikingly, since taxonomy is a central issue for ecological and conservational researches Brandon et al. In 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. Among other implications, aquatic macrophytes are highly productive and with an important structuring role on aquatic environments.

Rolon and Maltchik, 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. Our analyses showed that the studies dealt mostly with the influences of aquatic macrophytes on organisms and abiotic features.

Submerged aquatic plants probably received high attention due to the important structuring role that this group provides in aquatic habitats Jeppensen et al. Prediction and aquatic sciences.

Finally, it is also worth to note the lack of investigations directed to “hot” fields of Ecology, such as the impacts of invasive species, the role of limnolofa as foundation species mechanism of facilitation and the debates on diversity-stability and diversity-ecosystem functioning, among others. These studies funcamentos essential nowadays, since they can support conservation efforts. Global diversity of aquatic macrophytes in freshwater. Additionally, the historical roots of limnology in Neotropical regions are strongly correlated to investigations about ecosystem processes and functioning e.

Together with these investigations, basic researches aiming to describe unknown species are also necessary. Among other implications, aquatic macrophytes are known as highly productive Wetzel, and with an important structuring role on aquatic environments Jeppensen 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. This journal was also the favorite by international Brazilian articles on limnology until Melo et al.

The productivity of the C4 grass Eichinocloa polystachy a on the Amazon floodplain. Acta Oecologicavol. This is essential to support conservation efforts and to subsidize further investigations testing ecological hypotheses. The systematic, distribution, phytogeography and ecology of the terrestrial vegetation surrounding Santa Lagoon were the main issues of this book.

Planta daninhavol. In addition, USA is located in the same continent, what probably facilitates the cooperation with Neotropical countries. This suggests that international cooperation of Neotropical countries among themselves is still not conspicuous and should be stimulated.

In the current study, we performed a scientometric neoteopical of the scientific production devoted to Neotropical macrophytes in an attempt to find the main trends and gaps of researches devoted to this group. The title, abstract, author addresses, publication years and publication journals were recorded for our analyses.

Limnokoga it is a specific journal in the field, this seems to be the most reasonable choice. Hence, our results showed the paucity of studies on macrophyte biodiversity, essential to support conservation efforts and to subsidize further investigations testing ecological hypotheses.
