“…Ludwigia helminthorrhiza is distributed in Central America, Argentina, Mexico, Paraguay, Peru and Venezuela; Africa and Madagascar (Campos 2010). In Brazil, it is restricted to the states of Bahia, Ceará, Pará, Paraíba and Mato Grosso do Sul, associated to phytogeographic domains of the Amazon, Caatinga and Pantanal (Vieira 2015;Torres et al 2016).…”

This paper provides a taxonomic assessment and distribution details of the species of the genus Ludwigia L. (Onagraceae) for the Paraíba State, Northeastern Brazil. Six species were found: L. erecta (L.) H.Hara, L. helminthorrhiza (Mart.) H.Hara, L. hyssopifolia (G.Don) Exell, L. leptocarpa (Nutt.) H.Hara, L. nervosa (Poir.) H.Hara and L. octovalvis (Jacq.) P.H.Raven. Ludwigia nervosa was recorded for the first time in the studied area. Our taxonomic treatment comprises an identification key to the species. For each species, description, illustrations, taxonomic comments, flowering and fruiting data, geographic distribution map, and the conservation status for the studied area are provided. Among the recorded species, three were classified as “Near Threatened”, two as “Vulnerable” and one as “Critically Endangered”.

“…To test the hypothesis that campinaranas share fewer species with the black-water igapó surveyed (JNP and USDR) and other Brazilian wetland ecosystems, we compared our floristic data with herbaceous species inventories (Junk & Piedade 1993;Silva et al 2018;Chacon et al 2015;Pott & Pott 1997;Costa et al 2016;Torres et al 2016;Crema 2017) from other locations (Fig. 1, Tab.…”

Predicting the potential distribution of aquatic herbaceous plants in oligotrophic Central Amazonian wetland ecosystems

et al. 2021

Aquatic herbaceous plants are especially suitable for mapping environmental variability in wetlands, as they respond quickly to environmental gradients and are good indicators of habitat preference. We describe the composition of herbaceous species in two oligotrophic wetland ecosystems, floodplains along black-water rivers (igapó) and wetlands upon hydromorphic sand soils (campinarana) in the Parque Nacional do Jaú and the Reserva de Desenvolvimento Sustentável Uatumã in Central Amazonia, both protected areas. We tested for the potential distribution range (PDR) of the most frequent species of these ecosystems, which are the ones that occurred in at least two of the sampled wetlands, using species distribution models (SDMs). In total, 98 aquatic herbaceous species were recorded, of which 63 occurred in igapós and 44 in campinaranas. Most igapó species had ample PDRs across the Neotropics, while most campinaranas species were restricted to the Amazon Basin. These results are congruent with studies that described similar distribution patterns for tree and bird species, which emphasizes a high degree of endemism in Amazonian campinarana. However, we also found differences in the potential distribution of species between the two protected areas, indicating high environmental variability of oligotrophic ecosystems that deserve further investigation to develop effective measures for their conservation and protection.

As macrófitas aquáticas desempenham importantes funções no ambiente aquático, contribuindo para a estruturação ambiental e para o equilíbrio biológico. O presente estudo teve como objetivo conhecer a riqueza biológica e a distribuição de macrófitas aquáticas no rio Guaribas, município de Picos, Piauí, corpo d’água do semiárido fortemente alterado por ações antrópicas. Para isso, amostras foram coletadas mensalmente em cinco estações no trecho urbano do referido rio, no período de setembro/2018 a fevereiro/2019. Para a coleta dos vegetais utilizou-se um quadrante com lados de 25 cm (0,0625 m2). O material foi conduzido para o Laboratório de Botânica da Universidade Federal do Piauí, campus de Picos, onde foi lavado, separado e identificado. Foram listadas 24 espécies distribuídas em 13 famílias botânicas, entre as quais foram mais representativas: Poaceae (5), Cyperaceae (3), Fabaceae (3), Araceae (2), Convolvulaceae (2) e Polygonaceae (2). As formas biológicas mais comuns foram as anfíbias e emergentes, anfíbias e as flutuantes livres. A maior riqueza florística ocorreu nos meses de fevereiro e setembro com 18 e 16 espécies, respectivamente. Conclui-se que a diversidade de macrófitas aquáticas do rio Guaribas sofreu influência dos fatores ambientais e antrópicos sendo favorecida pelo evento de chuvas, sucessão de espécies e eutrofização do corpo d’água.RICHNESS AND DISTRIBUTION OF AQUATIC MACROPHYTES SPECIES IN THE GUARIBAS RIVER, PICOS, PIAUÍ STATEABSTRACTAquatic macrophytes play important roles in the aquatic environment, contributing to environmental structuring and biological balance. The present study had as objective to know how environmental factors interfere in the biological richness and in the distribution of aquatic macrophytes in theGuaribas river, water body of the semiarid strongly altered by anthropic actions, municipality of Picos, Piauí. For that, samples were collected monthly in five stations in the urban section of the referred river, from September / 2018 to February / 2019. For the sampling of vegetables, a quadrant with sides of 25 cm (0.0625 m2) was used. The material was taken to the Botany Laboratory ofthe Federal University of Piauí, Picos campus, where it was washed, separated and identified. 24 species were listed, distributed in 13 botanical families, among which were most representative: Poaceae (5), Cyperaceae (3), Fabaceae (3), Araceae (2), Convolvulaceae (2) and Polygonaceae (2). The most common biological forms were amphibians and emergent, amphibious and free floating.The greatest floristic richness occurred in the months of February and September with 18 and 16 species, respectively. It is concluded that the diversity of aquatic macrophytes in the Guaribas River was influenced by environmental and anthropic factors, being favored by the event of rains, succession of species and eutrophication of the water body.
