TLDR
The aquatic flora of Northeastern Brazil exhibits high species richness; however, there is a scarcity of records of aquatic macrophytes for the States of Alagoas, Rio Grande do Norte, Maranhao, Sergipe and Piaui.Abstract:
Aquatic plants have great influence on the structure and dynamics of aquatic ecosystems, thereby contributing considerably to biodiversity. In Brazil, knowledge of the biodiversity of aquatic macroflora is still limited. We present a checklist of aquatic macrophytes occurring in the northeastern region of Brazil through a bibliographic search. We recorded a total of 412 species, 217 genera and 72 families. The most representative families were Cyperaceae (70 species), Poaceae (38), Fabaceae (27) and Asteraceae (20). The States with highest number of species were Pernambuco (370), Bahia (360), Ceara (267) and Paraiba (261). The best-represented life forms were amphibious (193 species) and emergent (100). The aquatic flora of Northeastern Brazil exhibits high species richness; however, there is a scarcity of records of aquatic macrophytes for the States of Alagoas, Rio Grande do Norte, Maranhao, Sergipe and Piaui.read more

TL;DR: A rich aquatic flora in Northern Brazil is observed, in spite of scarcity of records for Acre, Rondonia and Tocantins; the unprecedent number of endemic species of Podostemaceae (25) and contrasting richness between SpeciesLink and Flora do Brasil are highlighted.

GEOGRAPHIC DISTRIBUTION OF THE THREATENED PALM Euterpe edulis Mart. IN THE ATLANTIC FOREST: IMPLICATIONS FOR CONSERVATION
TL;DR: In this paper, the potential geographic distribution of the threatened palm Euterpe edulis Mart (Arecaceae), an ecologically and economically important species inhabiting the Atlantic Forest biodiversity hotspot, was estimated using five different algorithms (BIOCLIM, GLM, MaxEnt, Random Forest and SVM).

TL;DR: In this article, a data repository for aquatic plants was developed to store information on species occurrence records in a standardized form considering: systematics, taxonomy, habit, life form, geographic distribution, hydrographic basin, wetland, bibliographic references and herbarium material.

Global diversity of aquatic macrophytes in freshwater
TL;DR: This analysis of the numbers and distribution of vascular macrophytes showed that whilst many species have broad ranges, species diversity is highest in the Neotropics, intermediate in the Oriental, Nearctic and Afrotropics, lower in the Palearctic and Australasia, lower again in the Pacific Oceanic Islands, and lowest in the Antarctic region.

Aquatic macrophytes potential for the simultaneous removal of heavy metals (buenos aires, argentina)
TL;DR: Three autochthonous floating macrophytes, common in pampean shallow lakes (Argentina), Pista stratiotes, Spirodela intermedia and Lemna minor were used in laboratory experiences for the simultaneously removal of several heavy metals resulting from anthropogenic activity, in order to simulate a naturally polluted environment.

Environmental predictors of the occurrence of exotic Hydrilla verticillata (L.f.) Royle and native Egeria najas Planch. in a sub-tropical river floodplain: the Upper River Paraná, Brazil
Wilson Treger Zydowicz Sousa,Sidinei Magela Thomaz,Kevin Murphy,Márcio José Silveira,Roger Paulo Mormul +4 more
TL;DR: In this paper, the authors conducted three surveys sampling for the presence of H. verticillata and E. najas and environmental variables aiming to answer: (1) How rapid is the colonization-regeneration process for both species? (2) Which habitats seem to be more susceptible to their colonization? (3) Which environmental factors can best predict their occurrence?
