“…To validate the model, both South America and North American regions were delineated. About 79.5% of the occurrence points were located in the United States of America or Mexico; in addition, S. minima was present in fourteen states of the United States of America [94], colonizing natural habitats in Florida [95], Texas, and Louisiana [96], so this region was chosen for validation. Approximately 98.9% of the points in the areas were inserted in very suitable regions, and 1.1% had moderate climatic suitability (Figure 7).…”

Invasive macrophytes are considered problematic in natural environments and hydroelectric reservoirs. Climate changes, the occurrences of watercourses, and biotic interactions influence biological invasions of macrophytes. The abundance of native species can be positively or negatively correlated with the occurrences of invasives. Urochloa subquadripara is an invasive in natural or disturbed habitats co-occurring with the natives Eichhornia crassipes and Salvinia minima in South America. Aquatic plant communities can be altered by climate change, so species distribution models (SDMs) are important tools for predicting invaded areas. This study aimed to apply an SDM to study correlations of U. subquadripara with the potential distributions of native species E. crassipes and S. minima. Occurrence data for U. subquadripara, E. crassipes, and S. minima were collected from databases and in consultation with the published literature. Parameters encompassing biological information of the species were entered into the CLIMEX software and used to generate the Ecoclimatic Index (EI). The species co-occurrence was performed based on multicriteria decision-making (MCDM), and weights were assigned using the analytical hierarchy process (AHP). It was observed that U. subquadripara, E. crassipes, and S. minima had a higher occurrence in tropical and subtropical regions. However, it is predicted that these species may move to high latitudes from climatic changes. Considering climate changes, such as the increase in temperature and CO2, the risk of invasion by U. subquadripara in the northern hemisphere is mainly in lakes, whereas the areas conducive to invasions are rivers and reservoirs in the southern hemisphere. In general, emerging and floating macrophyte species such as U. subquadripara, E. crassipes, and S. minima will be favored, causing suppression of submerged species. Therefore, identifying the potential distribution of these species allows the creation of pre-invasion intervention strategies.

“…A Salvinia minima (Salviniaceae) ocorre em quase todo território nacional, é abundante em áreas aquáticas ausente de movimentos e rica em matéria orgânica (RICHARD;RAMEY, 2007). É uma planta invasora altamente adaptável às condições ambientais, que causa obstrução de vias navegáveis e diminuição da disponibilidade de luz, reduz o oxigênio dissolvido, altera o pH e a qualidade da água (PARYS; JOHNSON, 2013).…”

Recebido em: 12/01/2021 Aceito em: 18/02/2021 Publicado em: 20/03/2021 RESUMO O objetivo foi avaliar a produção de mudas de pimenteiras-de-cheiro com o uso da macrófita Salvinia minima e carvão vegetal como substrato alternativo. O experimento foi conduzido em casa de vegetação, na UFAC em Rio Branco, Acre. As sementes para a produção das mudas foram obtidas de acessos no município de Rio Branco. O delineamento foi o inteiramente casualizado com cinco tratamentos e seis repetições, compreendidos pelas proporções: 100% substrato comercial (100% sc); 100% Salvinia minima (100% Sm); 80% Salvinia minima + 20% carvão vegetal (80% Sm+20% cv); 60% Salvinia minima + 40% carvão vegetal (60% Sm+40% cv), e 40% Salvinia minima + 60% carvão vegetal (40% Sm+60% cv). As variáveis avaliadas foram: altura de plantas (AP), diâmetro do colo (DC), massa seca da parte aérea (MSPA), massa seca radicular (MSR) e Índice de Qualidade do Desenvolvimento (IQD). As avaliações foram realizadas aos 54 dias após a semeadura. Houve efeito positivo do substrato para altura de plântulas, massa seca da parte aérea, massa seca radicular, massa seca total e Índice de Qualidade do Desenvolvimento. Não houve efeito significativo para o diâmetro do colo. A utilização de Salvinia minima e carvão vegetal promove melhor produção de mudas de pimenteiras-de-cheiro. Palavras-chave: Capsicum chinense. Macrófita. Qualidade de muda.

“…Research regarding Salvinia is concerned largely with its uses in aquatic bioremediation (Olguin et al 2002, Hoffmann et al 2004, Prado et al 2010, Ashraf et al 2011) and insect biocontrol (Flores and Carlson 2006, Schooler et al 2011, Parys and Johnson 2013. The few studies of fungi associated with Salvinia species are of Drechslera salviniae, which causes leaf spot on S. auricularia (Muchovej 1979, Muchovej and Kushalappa 1979, Barreto et al 2000, and Rhizoctonia solani and Alternaria alternata, which are reported to infect S. molesta and S. minima (Rayachhetry et al 2002, Babu et al 2003.…”

Violaceomyces palustris gen. et sp. nov. and a new monotypic lineage, Violaceomycetales ord. nov. in Ustilaginomycetes

Numerous strains of a novel yeast were isolated in Louisiana, USA, from the leaves of several palustrine plants, most frequently from the invasive aquatic ferns Salvinia minima and S. molesta. This fungus produced fast-growing colonies that were grayish violet to dark blue in culture and rapidly reproduced via production of copious ballistoconidia that germinated to form pseudohyphae. Colonies produced many two-celled yeasts that were distinctly hourglass-or peanut-shaped, and occurred singly or in chains. Phylogenetic analyses of translation elongation factor 1-α, β-tubulin and the nuc rDNA regions encompassing 28S D1-D2 domains, 18S and the internal transcribed spacers 1 and 2, including 5.8S, indicate this fungus is a member of Ustilaginomycetes but holds an isolated position, distinct from the two currently recognized orders, Ustilaginales and Urocystales. Here we describe Violaceomycetales ord. nov., Violaceomycetaceae fam. nov. and Violaceomyces palustris gen. et sp. nov. for this unusual fungus.
