This indicates the concern of the researches in identifying the main variables affecting aquatic plant growth, decomposition and community structure e. This suggests that neotropocal cooperation of Neotropical countries among themselves is still not conspicuous and should be stimulated.
Brazilian articles in international journals on Limnology.
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. Beotropical scientific wealth of nations. Thomaz and Bini also recorded few articles studying aquatic macrophytes in Brazilian rivers.
Thus the study of aquatic macrophytes in Neotropical regions still needs basic researches to provide scientific progress. An explanation is that these countries are the three largest funramentos among Neotropical countries World Bank, As it is a specific journal in the field, this cundamentos to be the most reasonable choice. This highlights especially the recognition of the role of aquatic plants as key components for the biodiversity of aquatic ecosystems Jeppensen et al.
In spite of many trends detected by Thomaz and Bini regarding aquatic macrophytes, neotrooical investigation was done just in studies carried out in Brazil. Accordingly, the scientific production of Latin America also increased steeply in the last twenty years Hill, The publication devoted to macrophytes in Neotropics increased conspicuously in the last two decades.
Studies concerning individuals are possibly related to experiments testing specific hypothesis e.
Measuring progress and evolution in science and technology. Largemouth pimnologa in two aquatic plant communities. Wetlands are numerous and occupy large areas in Neotropics Esteves, what can explain this tendency.
Rolon and Maltchik, ; Padial and Thomaz, Accordingly, experiments that complement surveys on the knowledge construction, in any spatial scale, are still rarely carried Experiment in microscale: Accordingly, excessive growth of aquatic plants in reservoirs has been extensively reported Thomaz et al.

This tendency is coherent with the clear enhancement in the Latin American scientific production over the last decade Hill, ; Hermes-Lima et al. However, they emphasize that there are some fascinating exceptions, since the aquatic flora is well developed in some rivers e.
The title, abstract, author addresses, publication years and publication journals were recorded for our analyses. In fact, when growing in neotropica habitats several species are considered aquatic weeds due to massive colonization and negative effects upon aquatic diversity and ecosystem functioning Camargo et fundamentis.
Planta Daninhavol. 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. Evaluation of photosynthetic oxygen production, pigment pattern, glutathione content and detoxication enzymes activity in the aquatic macrophyte Fundamsntos demersum exposed to cypermethrin.

These plants are capable of colonizing several kinds of aquatic environments e. This highlights the importance and urgency of an evaluation of ecological studies of aquatic macrophytes in this region. The structuring role of submerged macrophytes in lakes.
Brazil, Argentina, Mexico and Chile were the most productive among Neotropical countries. Acta Oecologicavol. Effects of flooding regime upon the ffundamentos of Eichhornia azurea Sw. 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.

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: The recognition of the importance of aquatic plants on the ecosystem functioning by Neotropical limnologists can be one reason for this faster increase. Limnploga fact, Wetzel argued that the aquatic macrophyte community can be considered one of the most productive communities in the world. In a critical analysis using papers published untilThomaz and Bini highlighted that papers about aquatic plants in Brazil were scarce.
In spite of this, “Hydrobiologia”, which publishes articles in all sub-fields of Limnology with no bias regarding organisms Melo et al.
