“…The Jacarecica II Dam is an important reservoir found in the Sergipe State and is described as a potential source of species with high potential to colonize and become weeds in other areas (Almeida & Fabricante, 2021). The studies concerning the aquatic macrophytes of the Sergipe State are recent and limited to species checklists (Almeida & Fabricante, 2020, 2021. Added to that, the area is considered a knowledge gap about aquatic macrophytes in northeastern Brazil (Moura-Júnior & Cotarelli, 2019).…”

“…Added to that, the area is considered a knowledge gap about aquatic macrophytes in northeastern Brazil (Moura-Júnior & Cotarelli, 2019). Anyway, the studies of Sergipe show a high richness of emergent macrophytes and a low and limited composition of other life-forms with various weedy free-floating species (Almeida & Fabricante, 2020, 2021.…”

“…The soils around Jacarecica II Dam are classified as red-yellow podzolic soils (COHIDRO, 2022) with a mosaic of bare soil, cultivation zones and fragments of Atlantic Forest. Previous studies suggest that weedy macrophytes species may be profiting from the anthropic changes that occurred in the reservoir area (Almeida & Fabricante, 2021).…”

“…It is located in the agreste region of Sergipe, in the municipalities of Malhador and Areia Branca. This reservoir receives water from Jacarecica River, Marcela Stream and from lots of small water bodies that are originated in the national park of Serra de Itabaiana, a protected area neighboring the reservoir (Almeida & Fabricante, 2021). The data sampling occurred between January 3 and May 6, 2021, comprising the summer which are warm and dry months.…”

“…Due the limitations imposed by the COVID-19 pandemic we were not able to collect and deposit plants as vouchers in herbarium collections. The species determination was performed through the comparison of photographs that were taken in the field and material previously sampled in the same region (Almeida & Fabricante, 2020, 2021. Whenever necessary, the images were sent to specialists to obtain the correct name for each species.…”

Aim Evaluate the structure of the aquatic macrophytes assembly of the Jacarecica II Dam, Areia Branca, Sergipe, and verify if distance from the margin is a driver for species richness, and composition in this environment. Methods We settled transects where we plotted quadrats and subplots. The transects were perpendicular in relation to the reservoir margin, and the first quadrat was placed on the margin with the four following ones completely over the water surface. We estimated cover area for each macrophyte species in each quadrat. Each species was also classified according to its life form. We calculated community indexes and tested the influence of the distance from the margin on the structure of macrophyte assemblies. Results We sampled 10 emergent and four free-floating species, resulting in a richness of 14 species. The species with higher importance value were weedy and ruderal species (Salvinia auriculata and Eichhornia crassipes). The distance to the margin caused changes in macrophyte assembly and presented negative relation with species richness. Conclusions The studied assembly presents few species, with some presenting great dominance. This dominance reflects the anthropization of these habitats. Besides, the species composition and richness are modified in the sense that emergent and free-floating species co-occur in marginal quadrats, but only free-floating species occur in quadrats that are in areas that are more distant from the reservoir margin.

We aimed to characterize the floristic composition, detect the life forms, and provide an identification key for the macrophyte species of the Capitão Poço river micro-basin in the State of Pará, located in the Eastern Amazon. The collected specimens were identified and deposited in the HCP herbarium. We found 23 species distributed in 19 genera and 14 families of macrophytes. The families with the highest species richness were Cyperaceae (six spp.), Poaceae (three spp.), Onagraceae and Plantaginaceae (two spp. each). We present here the first record of Dichanthelium aequivaginatum from the Brazilian Amazon and the Northern region of Brazil. We suggest that floristic-taxonomic studies of macrophytes in the hydrographic basins of the northeastern region of Pará should be intensified in order to better understand the regional flora of this group.

As plantas carnívoras são organismos que em sua evolução desenvolveram mecanismos adaptativos para conseguir suprir suas necessidades nutricionais por meio da captura e absorção de animais. O estudo objetivou inventariar as plantas carnívoras do Parque Nacional Serra de Itabaiana, Sergipe. O inventário das plantas carnívoras foi realizado por meio de caminhadas (busca ativa) pelos locais de estudo. Foram realizadas 10 expedições as localidades com duração média de 4 h. cada uma. As espécies amostradas foram classificadas quanto ao tipo de armadilhas em: (i) jaula; (ii) sucção; (iii) folhas colantes; (iv) ascídios. Foram amostradas 11 espécies distribuídas em três gêneros e duas famílias. A família Droseraceae apresentou uma espécie (9,1%) e a família Lentibulariaceae, 10 espécies (90,9%). O tipo de armadilha mais comum entre as espécies foi a de sucção (90,9%), seguida por semiativa (9,1%). Conclui-se que o Parque Nacional Serra de Itabaiana, Sergipe apresenta uma elevada riqueza de espécies carnívoras.
