This suggests that international cooperation of Neotropical countries among themselves is still not conspicuous and should be stimulated. Emergent aquatic macrophytes are also highly studied, possibly due to the importance of this plants that may have extremely high primary production Piedade et al. Submerged aquatic plants probably received high attention due to the important structuring role that this group provides in aquatic habitats Jeppensen et al.

Environmental factors as predictors of aquatic macrophyte richness and composition in wetlands of southern Brazil. The studies conducted in reservoirs are probably related to the problems that aquatic macrophytes cause due to excessive growth.

However, Warming also described the aquatic and amphibian vegetation of this lagoon in details, fundzmentos the first inferences about aquatic plant zonation and succession. Accordingly, experiments that complement surveys on the knowledge construction, in any spatial scale, are still rarely carried Experiment in microscale: Hence, our results showed the paucity of studies on macrophyte biodiversity, essential to support conservation efforts and to subsidize further investigations testing ecological hypotheses.

Environmental influences on aquatic plants in freshwater ecosystems. The structuring role of submerged macrophytes in lakes.

Moreover, a reliable assessment of the biological diversity is only reached by improving cundamentos knowledge Brandon et al. In fact, Irgang and Gastal Jr pointed the lack of taxonomical studies in Brazil.

In the current study, we performed a scientometric analysis of the scientific production devoted to Neotropical macrophytes in an attempt to find the main trends and gaps of researches devoted to this group. This is extremely relevant, since aquatic biodiversity has been related to spatial heterogeneity Grenouillet et al. Brazil, Argentina, Mexico and Chile were the most productive among Neotropical countries.

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. The analysis was based on abstracts of papers published between and April Thus the study of aquatic macrophytes in Neotropical regions still needs basic researches to provide scientific progress. Et Bidrag til den biologiske Plantegeografi”, is one of the first publication concerning Neotropical aquatic macrophytes Thomaz and Bini, Thomaz and Bini stressed that the variety of environments is also an important factor accounting for the interest on aquatic macrophytes in Brazil.

Furthermore, free-floating aquatic macrophyte species are highly productive in suitable environments Cook, ; Carignan and Neiff, ; Talling and Lemoalle, In spite of this, “Hydrobiologia”, which publishes articles in all sub-fields of Limnology with no bias regarding organisms Melo et al.

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.

The biology of aquatic vascular plants. However, a precise view of ecological studies using aquatic macrophytes is necessary to reach a reliable evaluation of the scientific production. Neitropical, even considering authors from other countries, studies were also frequently conducted in these three countries Brazil: In addition, limnological studies clearly increased in Brazil after Melo et al.

Neiff, ; Junk, ; Esteves, A critique for Ecology. Our analyses showed that the studies dealt mostly with the influences of aquatic macrophytes on organisms and abiotic features.

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. The study of aquatic macrophytes in Neotropics: Ecological Dynamics of Tropical Inland Waters. This could also be explained by the high importance of aquatic plant communities for the production of organic matter Piedade et al. Rolon and Maltchik, Rolon and Maltchik, ; Padial and Thomaz, Biodiversity hotspots for conservation priorities.

In fact, Wetzel argued that the aquatic macrophyte community can be considered one of the most productive communities in the world. Thomaz and Bini also recorded few articles studying aquatic macrophytes in Brazilian rivers. Accordingly, the scientific production of Latin America also increased steeply in the last twenty years Hill, 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.

Specifically, we asked the following questions: 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. Chemical composition of floating aquatic macrophytes used to treat of aquaculture wastewater.

Among other implications, aquatic macrophytes are highly productive and with an important structuring role on aquatic environments.

I ; Bini, LM. As it is a specific journal in the field, this seems to be the most reasonable choice.

The high attention of this subject reflects the recognition that macrophytes cause strong changes in aquatic ecosystems e. The test of these hypotheses could be done by experiments could be then reached by experiments. Among other implications, aquatic macrophytes are known as highly productive Wetzel, and with an important structuring role on aquatic environments Jeppensen et al.

After this, only the papers authored by researchers from Neotropical countries Mexico, Mesoamerican countries and South American countries were selected by using the information on the country of affiliation of the authors.
