1. The invasive tropical tanner grass decreases diversity of the native aquatic macrophyte community at two scales in a subtropical tidal river
ABSTRACT The tropical tanner grass, Urochloa arrecta, is one of the worst aquatic plant invaders in Brazilian freshwater ecosystems. This study aimed to compare beds of macrophytes dominated and without U. arrecta in the Guaraguaçu River, a subtropical tidal river in South Brazil, to analyze effects that this invasive grass has on the biodiversity of native

2. Enzymatic efficiency of the decomposing microbiota: what does really matter for aquatic macrophytes invasions?
ABSTRACT Biological invasions have negative impacts on different ecosystem-level functions, such as nutrient cycling. In aquatic environments, exotic litter can change the activity of the decomposer microbiota. We tested whether litter quality, litter decay, and enzyme activity differed between nativeEgeria densaand exoticHydrilla verticillata. The invasive

3. An update on the knowledge of aquatic macrophytes in Northeast Brazil
Resumo Atualizamos o primeiro checklist de macrófitas aquáticas do Nordeste do Brasil (Primeira Flora), que incluiu dados coletados até 2010, com uma nova lista de espécies baseada em dados de trabalhos publicados entre 2011 e 2017 (Nova Flora). Juntas, estas listagens registram 637 espécies de 89 famílias, com ênfase em espécies estritamente anfíbi

4. Nassarius foveolatus (Gastropoda, Nassariidae), a new record of an exotic species in Brazil
Abstract Exotic species are those that occur in an area beyond their natural limit and they are considered invasive when they cause harm to the economy, environment, or human health. In coastal environments, ballast water and inlays on the hull and other parts of vessels are the main ways of introducing invasive aquatic alien species. Nassarius foveolatus (D

5. Bioaccumulation, Growth and Photosynthetic Response of a New Found in Bulgaria Invasive Species Lemna minuta and L. valdiviana to Heavy Metal Pollution
RESUMO: Metais pesados podem ser encontrados no meio ambiente como ingredientes naturais ou de práticas agrícolas, industriais e químicas. Este estudo foi conduzido com o objetivo de traçar o potencial das plantas aquáticas L. minuta e L. valdiviana para a bioacumulação de Cu, Cd e Pb a partir de água contaminada com baixos níveis desses elementos.

6. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

8. Decomposição aeróbia e anaeróbia in vitro de Egeria densa Planch. e Hydrilla verticillata (L.f.) Royle de reservatórios tropicais
Nesse trabalho foi avaliada a decomposição aeróbia e anaeróbia das espécies submersas Egeria densa Planch. e Hydrilla verticillata (L.f.) Royle, importantes invasoras em reservatórios tropicais. Foi analisado o decaimento de matéria orgânica, mineralização do carbono, grau de humificação do material lixiviado, conteúdo de fibras, condutividade,

9. Abiotic factors controlling the establishment and abundance of the invasive golden mussel Limnoperna fortunei.
Limnoperna fortunei (Bivalvia, Mytilidae), a freshwater bivalve native to Southern Asia, has been an invasive species in South America since 1991. It spread upstream in the La Plata basin reaching the Paraguay River in the vicinity of the Pantanal wetland, Brazil, around 1998. The role of abiotic factors in controlling establishment and abundance of this spe

10. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

12. BIOLOGIA POPULACIONAL DO CARANGUEJO DE ÃGUA DOCE Trichodactylus petropolitanus NO CÃRREGO DA MINA, CAÃAPAVA, SP: MONITORAMENTO AMBIENTAL A PARTIR DE ESTUDO DE POPULAÃÃES ANIMAIS / Population biology of the freshwater crab Trichodactylus petropolitanus in the CÃrrego da Mina, CaÃapava, SP: environmental monitoring from animal population studies
The freshwater crab Trichodactylus petropolitanus (GÃldi, 1886), is an endemic Brazilian species with occurrence in the States of Minas Gerais, Rio de Janeiro, SÃo Paulo, Paranà and Santa Catarina, being its distribution widely coincident with the domain of the almost extinct Mata AtlÃntica forest. Besides its importance in the trofic web of lotic system
