Fundamentos de limnología neotropical

Rolon and Maltchik, ; Padial and Thomaz, This is extremely relevant, since aquatic biodiversity has been related to spatial heterogeneity Grenouillet et al. The papers were selected using the following combination of words on the search field: Hence, our limnoloha showed the paucity of studies on macrophyte biodiversity, essential to support conservation efforts and to subsidize further investigations testing ecological hypotheses.

Global diversity of aquatic macrophytes in freshwater.

The high attention of this subject reflects the recognition that macrophytes cause strong changes in aquatic ecosystems e. Aquatic macrophytes comprises a diverse group of organisms including angiosperms, ferns, mosses, liverworts and some macroalgae that occur in seasonally or permanently wet environments.

Thus, our results concerning studies of macrophytes in Neotropics indicate that most investigations are still carried in a preliminary way.

A great variety of journals were used to publish studies dd aquatic plants and “Hydrobiologia” was the main one, publishing ca. 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.

A total of papers were analyzed, considering the criteria delineated in our Methods. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. Brazilian articles in international fundamenttos on Limnology.

The productivity of the C4 grass Eichinocloa polystachy a on the Amazon floodplain. The analysis was based on abstracts of papers published between and April 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.

The structuring role of submerged macrophytes in lakes. In fact, Irgang and Gastal Jr pointed the lack of taxonomical studies in Brazil.

Services on Demand Journal.

Moreover, this appraisal could subsidize biodiversity conservancy efforts, since macrophytes are key for conservation of several aquatic e. In fact, high scientific production is associated with economic development May, Thomaz and Bini also recorded few articles studying aquatic macrophytes in Brazilian rivers.

In addition, researches aiming to describe unknown species are still necessary. Abundance and species richness as a function of food resources and vegetation structure: Moreover, a reliable assessment of the biological diversity is only reached by improving taxonomical knowledge Brandon et al. Together with these investigations, basic researches aiming to describe unknown species are also necessary.

This classical fundamenhos was published in by Eugene Warming who is considered by Arthur Tansley “the father of the modern plant ecology” Godwin, The scientific impact of nations.

Specifically, we asked the following questions: Environmental factors as predictors of aquatic macrophyte richness and composition in wetlands of southern Brazil. This tendency is coherent with the clear fundanentos in the Latin American scientific production over the last decade Hill, ; Hermes-Lima et al. In a recent review, Chambers et al. The recognition of the importance of aquatic plants on the ecosystem functioning by Neotropical limnologists can be one reason for this faster increase.

Largemouth diet in two aquatic plant communities. On the other hand, studies at community level frequently aim to evaluated patterns in the distribution of the abundance and in the diversity of plant communities, as well as the environmental variables affecting these metrics 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. Additionally, these papers were also related to studies concerning the management and control of macrophytes.

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. Commonly, four morphotypes or life forms are used to classify aquatic macrophytes: Ecological studies involving aquatic plants substantially increased in the last years. Challenging Wallacean and Linnean shortfalls: Prediction and aquatic sciences. Fish assemblages with Egeria in a tropical reservoir: Thus the study of aquatic macrophytes in Neotropical regions still needs basic researches to provide scientific progress.

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.

Therefore, scientometrics considering publications about aquatic macrophytes in Neotropical ecosystems are essential to the progress of this relevant research df.
