Abstract	With the aim of documenting aquatic macrophyte succession on floating meadows and its relationship with histosol thickness, we sampled six-hundred 0.5 × 0.5 m2 plots of ten randomly chosen floating meadows in Baía Grande lake (Aquidauana, MS, Brazil). The floating meadows were marked in order to follow, since August 2014–August 2015, floristic and phytosociological changes and to assess their relationship with histosol thickness. We recorded 58 species belonging to 23 families and 47 genera. The richest families were Poaceae (8 species), Asteraceae (7) and Cyperaceae (6). Four species stood out for their high importance value: Oxycaryum cubense (Poepp. & Kunth) Lye, Ludwigia helminthorrhiza (Mart.) H. Hara, Eichhornia azurea (Sw.) Kunth and Vigna longifolia (Benth.) Verdc. Histosol thickness of the floating meadows varied from 1 to 51 cm, making it possible to classify them into three classes. We observed that most species (63.3%) were in the initial and intermediate stages of succession (1–34 cm histosol) and that species were replaced as a function of histosol thickness. We conclude that floating meadows have succession stages with various species of aquatic macrophytes related with histosol thickness, but species composition regarding succession stages differs from other water bodies in the Pantanal wetland.

Abstract	A associação entre as formas biológicas flutuante e epífita, relacionadas a macrófitas aquáticas, constitui o que se chama genericamente de ilha flutuante. Esta denominação é aplicada ao estabelecimento de uma ou mais epífitas sobre indivíduos vivos de espécies flutuantes, como sinônimo de camalotal ou, ainda, para se referir à vegetação flutuante que se desenvolve sobre um solo orgânico em decomposição (histossolo). Realizou-se o levantamento das espécies presentes em cinco baceiros nas sub-regiões pantaneiras do Abobral e Miranda e o estabelecimento das similaridades florísticas entre estes, a fim de evidenciar aspectos da dinâmica sucessional de ilhas flutuantes. Foram encontradas 66 espécies de macrófitas aquáticas epífitas, distribuídas em 27 famílias, sendo Cyperaceae e Poaceae as mais representativas. O número de espécies por baceiro variou de 7 a 39, sendo os táxons comuns a todos esses Ludwigia leptocarpa (Nutt.) H. Hara e Oxycaryum cubense (Poepp. & Kunth) Palla, ao nível específico, e Asteraceae, Cyperaceae, Onagraceae, Poaceae e Polygonaceae, com relação às famílias. Outras formas biológicas, além da epífita, foram encontradas associadas aos baceiros, ou ainda, se mostraram adaptadas às condições do histossolo, podendo ser consideradas " epífitas casuais" . Baceiros em estágios sucessionais mais próximos apresentam maior similaridade florística e, no geral, quanto mais avançada a sucessão natural, maior a riqueza específica. The association between floating and epiphytic biological forms, regarding aquatic macrophytes, creates what are called floating mats. This concept refers to the establishment of one or more epiphytes on live individuals of floating species, as a synonym of " camalotal," or applied to floating vegetation that grows on organic soil in decomposition (histosol). A checklist of species was made of five floating mats in the Abobral and Miranda Pantanal Wetlands and floristic similarities among these mats were calculated to show aspects of sucessional dynamics on floating mats. A total of 66 species of epiphytic aquatic macrophytes were found, distributed in 27 families, Cyperaceae and Poaceae being the most representative. The number of species per mat varied from 7 and 39, with some taxa common to all mats, such as Ludwigia leptocarpa (Nutt.) H. Hara and Oxycaryum cubense (Poepp. & Kunth) Palla, at the specific level, and Asteraceae, Cyperaceae, Onagraceae, Poaceae and Polygonaceae, at the family level. Other biological forms besides epiphytes were found associated with " baceiros" or adapted to histosol conditions, being considered " casual epiphytes" . " Baceiros" in similar successional stages of development have high floristic similarity, and in general, the more advanced the natural succession, the higher the number of species.

Abstract	The âPantanalâ wetland is one of the largest centers of diversity of aquatic macrophytes of Brazil. The objective of this work was to present a checklist of aquatic macrophytes, and to investigate structure and patterns of occurrence regarding physico-chemical parameters, at Amolar, in the Paraguay River sub-region, in the mid-western âPantanalâ wetland, CorumbÃ¡ (MS). No previous aquatic plant study has been carried out there so far. The study was conducted in June 2009 in 391 plots (0.5Â ÃÂ 0.5Â m). We recorded 65 species of aquatic macrophytes, from 49 genera and 27 families. The richest families were Fabaceae, Poaceae, Convolvulaceae, Onagraceae, and Lentibulariaceae. The most representative life forms were emergent and free floating, comprising the most frequent species: Hymenachne amplexicaulis (Rudge) Nees, Salvinia auriculata Aubl., Ricciocarpos natans (L.) Corda, Lemna aequinoctialis Welw. and Azolla filiculoides Lam. presented the highest relative cover, as well as the highest importance value, followed by S. auriculata. The structure of the community of aquatic macrophytes presents relation with physico-chemical variables, chiefly depth: many species occurred exclusively in shallow areas and others in deep zones. The life forms partially explain the species zonation of macrophytes in relation to depth.

Abstract	Neotropical aquatic ecosystems have a rich aquatic flora. In this report, we have isted the aquatic flora of various habitats of the upper Paraná River floodplain by compiling data rom literature and records of our own continuous collections conducted during the period 2007-2009. Our main purposes were to assess the macrophyte richness in the Paraná floodplain, to compare it with other South American wetlands and to assess whether the number of species recorded in South American inventories has already reached an asymptote. We recorded a total of 153 species of macrophytes in the Upper Paraná River floodplain, belonging to 100 genera and 47 families. In our comparative analysis, a clear floristic split from other South American wetlands was shown, except for the Pantanal, which is the closest wetland to the Paraná floodplain and, therefore, could be considered a floristic extension of the Pantanal. The species accumulation curve provides evidence that sampling efforts should be reinforced in order to compile a macrophyte flora census for South America. The high dissimilarity among South American wetlands, together with the lack of an asymptote in our species accumulation curve, indicates that the sampling effort needs to be increased to account for the actual species richness of macrophytes in this region. Rev. Biol. Trop. 59 (2): 541-556. Epub 2011 June 01. Los ecosistemas acuáticos neotropicales tienen una rica flora acuática. En este informe, hemos hecho una lista de la flora acuática de diversos hábitats de la alta planicie de inundación del río Paraná mediante la compilación de datos de la literatura y los registros de nuestras colecciones propias realizadas durante el período 2007-2009. Nuestros principales objetivos fueron evaluar la riqueza de macrófitos en la llanura aluvial del Paraná, para compararlo con otros humedales de América del Sur y evaluar si el número de especies registradas en los inventarios suramericanos ya han alcanzado una asíntota.

Abstract	O Pantanal, por ser alagável, é ambiente favorável ao desenvolvimento de muitas plantas aquáticas. Para atender demandas de levantamentos florísticos regionais, fez-se a listagem das macrófitas aquáticas do Pantanal, com base em coletas depositadas nos Herbários CPAP (EMBRAPA), COR (Universidade Federal de Mato Grosso do Sul), CH (Universidade Federal de Mato Grosso) e K (Kew). Até o momento, foram levantadas 242 espécies, distribuídas em 106 gêneros e 54 famílias. As famílias mais numerosas são Poaceae (22 espécies), Cyperaceae(17), Leguminosae e Scrophulariaceae(14), Alismataceae e Onagraceae(13), Pontederiaceae(11), Lentibulariaceae(10), Characeae(9), emnaceae, Malvaceae e Nymphaeaceae(8). A maioria das demais famílias apresentam uma ou duas espécies cada. Quanto à forma biológica, 39% são plantas emergentes, 28% anfíbias, 11,5% flutuantes fixas, 8% flutuantes livres, 8% submersas fixas, 3,8% submersas livres e 1,7% epífítas. Os principais gêneros em número de espécies são Nymphaea, Utricularia, Echinodorus, Ludwigia, Polygonum, Aeschynomene, Cyperus, Eleocharis e Bacopa. The Pantanal, being a wetland, is a favorable environment for the development of many aquatic plants. This list of aquatic macrophytes of the Pantanal was made based on field collections, deposited at Herbarium CPAP (EMBRAPA), COR (Universidade Federal de Mato Grosso do Sul), CH (Universidade Federal de Mato Grosso) and K (Kew), to support regional floristic surveys. Until present, 242 species were listed, distributed within 106 genera and 54 families. The most numerous families were Poaceae (22 species) Cyperaceae(17), Leguminosae and Scrophulariaceae(14), Alismataceae and Onagraceae(13), Pontederiaceae (11), Lentibulariaceae(10), Characeae(9), Lemnaceae, Malvaceae andNymphaeaceae(8). The majority of other families has one or two species each. The life form spectrum includes 39% emergent plants, 28% amphibious, 11,5% rooted floating, 8% free floating, 8% rooted submerged, 3,8% free submerged and 1,7% epiphytes. The most important genera in number of species are Nymphaea, Utricularia, Echinodorus, Ludwigia, Polygonum, Aeschynomene, Cyperus, Eleocharis and Bacopa.

Abstract	Analisou-se quantitativamente uma comunidade de macrófitas aquáticas associada ao Rio Miranda, Pantanal, Mato Grosso do Sul utilizando dois métodos de amostragem: interseção linear e parcelas. Ao todo foram catalogadas 36 espécies, distribuídas em 31 gêneros e 20 famílias, sendo Poaceaea família com maior riqueza específica (5 spp.), seguida por Malvaceae (4), Asteraceae, Araceae, Convolvulaceae e Polygonaceae representadas por três espécies cada. Polygonum acuminatum foi a espécie que apresentou maior valor de importância (IVI) para ambos os métodos. O índice de diversidade de Shannon (H’) foi de 2,44 para o método da interseção linear e de 2,47 para o método das parcelas. Para ambos os métodos, a curva de rarefação demonstrou tendência à estabilização, indicando suficiência amostral. Os resultados obtidos foram similares para as duas metodologias, indicando ambas são apropriadas para estudos quantitativos com esta comunidade.

Abstract	Realizou-se o levantamento de plantas aquáticas da família Lemnaceae no Pantanal do Mato Grosso e Mato Grosso do Sul, a qual está representada por nove espécies, distribuídas em quatro gêneros. Das espécies encontradas somente Wolffia brasiliensis Wedd. e Lemna valdiviana Phil. haviam sido registradas no Pantanal. As demais espécies são Spirodela intermedia W. Koch, Lemna aequinoctialis Welw., L. minuta Kunth, in Humb., Bonp. & Kunth, Wolffiella welwitschii (Hegelm.) Monod, W. lingulata (Hegelm.) Hegelm., W. oblonga (Phil.) Hegelm. e Wolffia columbiana H. Karst. As Lemnaceae ocorrem em todas as 10 sub-regiões do Pantanal, com o maior número de espécies na sub-região do Nabileque, de solos mais férteis. A survey of aquatic plants belonging to the family Lemnaceae was carried out in the Pantanal wetland (States of Mato Grosso and Mato Grosso do Sul), represented by nine species, divided into four genera. Only two of the reported species had been previously cited for the Pantanal, Wolffia brasiliensis Wedd. and Lemna valdiviana Phil. The other species are Spirodela intermedia W. Koch, Lemna aequinoctialis Welw., L. minuta Kunth, in Humb., Bonp. & Kunth, Wolffiella welwitschii (Hegelm.) Monod, W. lingulata (Hegelm.) Hegelm., W. oblonga (Phil.) Hegelm., and Wolffia columbiana H. Karst. Lemnaceae occurs in all 10 subregions of the Pantanal, with a higher number of species in the Nabileque subregion, where soils are more fertile.
