“…Likewise we observed in this study, the richest families (Poaceae, Fabaceae, Onagraceae and Lentibulariaceae) are also well represented in surveys on aquatic macrophytes in the Pantanal (Rocha et al 2007, Silva & Carniello 2007, Pivari et al 2008 and other wetlands in Brazil (Meyer & Franceschinelli 2011, Aona et al 2015, Moura-Júnior et al 2015, Pivari et al 2019.…”

The objective of this study was to characterize the floristic and phytosociological composition of aquatic macrophytes occurring on the nearshore and on floating meadows of a large oxbow lake in the Pantanal wetland, in order to identify the degree of similarity between these biological compartments. Therefore, we sampled 100 plots of 0.5 x 0.5 m on floating meadows and 100 nearshore. We recorded 42 species, being 30 nearshore and 38 on floating meadows. The richness observed on floating meadows was little superior to the recorded nearshore, and the similarity between the compartments was relatively high (Jaccard = 61.90). Four species occurred exclusively nearshore, while 12 species were restricted to floating meadows. The outstanding species for their frequency and a high percentage of cover nearshore were Ludwigia helminthorrhiza (Mart.) H.Hara and Eichhornia azurea (Sw.) Kunth. On floating meadows, Cyperus blepharoleptos Steud. presented the highest importance value (61.3). The emergent and amphibious life forms were the most common in both compartments. The similarity between both formations is an expected outcome, once the floating meadows can develop from nearshore plants and contact them during displacements within the lake. We highlight the high number of exclusive species recorded on floating meadows, which can be explained by environmental (related to the interaction between species and environmental characteristics) or spatial factors (dispersal capacity) that favor the colonization of the floating meadows by species absent nearshore.

“…The seasonality of other life forms, such as oating and submerged plants, may prevent them from being recorded in the eld, since many appear in wetlands for only a short time; this is re ected in the lower number of species and survey records. Accuracy in determination and description of life forms often requires that studies be conducted for extended periods and over several hydrological cycles (Pivari et al 2019).…”

“…Floristic studies in wetlands in Brazil have continuously increased in sampling areas and number of species (Pivari et al 2019). The present ndings expand the available information on Amazon areas and habitats, and also increase the knowledge of species of aquatic macrophytes that occur in transitional areas such as southern Amazonia.…”

Southern Amazonia potentially harbors a wide diversity of aquatic macrophyte species because of its diverse wetland habitats and location in the Amazon-Cerrado transition zone, the two largest biogeographic domains in South America. We inventoried the taxonomic diversity of aquatic macrophytes in the region, including endemism, habitats, species life forms, and floristic comparisons with other Brazilian regions. We found a high number of species of aquatic macrophytes for the southern Amazon region, comparable to extensive inventories in larger areas in southern, northeastern, and northern regions of Brazil. We recorded 688 species of aquatic macrophytes in 299 genera and 95 families, of which 66 species are new records, 89 endemic, and 5 exclusive to Brazilian Amazonia. We present new records of aquatic macrophyte species, together with their degree of endemism and occurrence restricted to the region. The macrophyte species list of southern Amazonia showed 60% similarity to inventories in the Xingu basin and in northern Brazil. This high diversity of aquatic macrophytes in the Southern Amazonia, with endemic species and others with restricted ranges, emphasizes the importance of conserving wetlands and vegetation types where they grow in the region.

“…This study is part of a national initiative aiming to provide a Brazilian checklist for wetland ecosystems. Subsets for the north and northeast (Moura Júnior et al 2013;2015) and, more recently, the southeast (Pivari et al 2018) have been already been published. Thus, in this study, we addressed the following questions: (I) how many species are recorded in South Brazil?…”

Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist of aquatic vascular plants of South Brazil and establishes their floristic affinities with bordering South America phytogeographical domains. The checklist was based on 52 sources, including 35 floristic lists, 17 regional taxonomic studies, and information from an electronic database on wetlands of South Brazil. Floristic similarities with published checklists for neighbouring regions were assessed. A total of 780 species distributed in 277 genera and 85 families of vascular plants were reported for South Brazil. Families with higher species richness were Cyperaceae (128), Poaceae (102), Asteraceae (69), Plantaginaceae (21), Lentibulariaceae (20), and Onagraceae (20). The most represented genera were Eleocharis (41) and Cyperus (24). A cluster analysis revealed high similarity with Iberá (Argentinian Chaco), Pampa and Atlantic Forest, and low similarity with Pantanal, Caatinga and the Amazon Rainforest. The high number of aquatic plant families recorded relative to temperate and tropical climates suggests a zone of biogeographical overlap in Southern Brazil. The compiled data set reveals high biodiversity of wetlands of South Brazil, provides a baseline for future research, and highlights the need for regional conservation planning.
