Las especies del complejo Laurencia son elementos importantes en la estructura y diversidad de los ecosistemas costeros. Por primera vez, se analiza la distribución geográfica del complejo dentro de la plataforma cubana, sus áreas marinas protegidas y se identifican áreas potenciales endémicas, considerando las ecozonas en que se dividió la plataforma. A la fecha, se han inventariado 19 especies, de estas 10 pertenecen a Laurencia, una a Osmundea, cinco a Palisada, dos a Yuzurua, y se incorporó Laurenciella como nuevo género para Cuba. La distribución fue desigual, con un alto número de especies y puntos de ocurrencia, especialmente en las regiones Occidental y Central de la costa norte. El análisis de parsimonia de endemicidad indicó dos ecozonas, una en Habana-Matanzas y otra en la Costa Nordeste, sustentadas por tres y dos especies endémicas, respectivamente. Species of the Laurencia complex are important elements in the structure and diversity of coastal ecosystems. For the first time, we analyzed the geographical distribution of the complex within the Cuban shelf, its marine protected areas and identified potential endemic areas, considering the ecozones into which the shelf was divided. To date, 19 species have been inventoried, of which 10 belong to Laurencia, one to Osmundea, five to Palisada, two to Yuzurua, and Laurenciella a new record of genus for Cuba.

La especie Basella alba se conoce popularmente como bertalha india y se consume ampliamente en forma de ensaladas, por ejemplo. El objetivo de este estudio fue evaluar las etapas iniciales de crecimiento y la producción de metabolitos secundarios en diferentes sustratos. Transcurridos 90 días desde el inicio de la plantación (pleno sol), en suelo arenoso mezclado con diferentes sustratos, se determinó el efecto de los sustratos sobre el crecimiento y producción de metabolitos secundarios en las hojas. Los resultados indicaron que el tratamiento con la adición de 70% de vermicompost indujo el mayor crecimiento y la mejor concentración de compuestos fenólicos y flavonoides. Sin embargo, la mayoría de los tratamientos dieron como resultado la producción de heterósidos cardiotónicos, que pueden causar problemas de salud. The species Basella alba is popularly known as Indian bertalha and is widely consumed in the form of salads, for example. Due to its potential for use, the objective of this study was to evaluate the initial stages of growth and the production of secondary metabolites in different substrates. After 90 days from the beginning of planting (full sun), in sandy soil mixed with different substrates, the effect of substrates on growth and the production of secondary metabolites in leaves was determined. The results indicated that the treatment with the addition of 70% of vermicompost induced the highest growth and the best concentration of phenolic and flavonoid compounds. However, most of the treatments resulted in the production of cardiotonic heterosides, which can cause health problems.

Byrsonima species present floral monomorphism and sharing visitor/pollinator guild. These traits suggest the hypothesis evaluation of reciprocal inter-incompatibility between two syntopic Byrsonima species: B. pachyphylla and B. crassifolia. Pollen tube growth with similar behavior was observed in the stigmatic surface, pistil canal, ovary and micropylar channel to both species. In addition, partial self-incompatibility in self-pollination with greater fruiting in autogamy was observed. Cross-pollination and self-pollination coexist, and reciprocal intercompatibility occurs. Prezygotic isolation mechanisms are unlikely by the absence of abnormal pollen tubes, higher fruiting production and absence of hybrids in the study site. Las especies de Byrsonima presentan monomorfismo floral y comparten gremio de visitantes/polinizadores. Estos rasgos sugieren la evaluación de hipótesis de interincompatibilidad recíproca entre dos especies sintópicas de Byrsonima: B. pachyphylla y B. crassifolia. Se observó el crecimiento del tubo polínico con comportamiento similar en la superficie estigmática, canal del pistilo, ovario y canal micropilar de ambas especies. Además, se describió la autoincompatibilidad parcial en la autopolinización con mayor fructificación en la autogamia. La polinización cruzada y la autopolinización coexisten y se produce una intercompatibilidad recíproca. Los mecanismos de aislamiento precigóticos son improbables por la ausencia de tubos polínicos anormales, producción de frutos y ausencia de híbridos en la área de estudio.

These traits suggest the hypothesis evaluation of reciprocal inter-incompatibility between two syntopic Byrsonima species: B. pachyphylla and B. crassifolia. Pollen tube growth with similar behavior was observed in the stigmatic surface, pistil canal, ovary and micropylar channel to both species. In addition, partial self-incompatibility in self-pollination with greater fruiting in autogamy was observed. Cross-pollination and self-pollination coexist, and reciprocal intercompatibility occurs. Prezygotic isolation mechanisms are unlikely by the absence of abnormal pollen tubes, higher fruiting production and absence of hybrids in the study site.\u0000 Las especies de Byrsonima presentan monomorfismo floral y comparten gremio de visitantes/polinizadores. Estos rasgos sugieren la evaluación de hipótesis de interincompatibilidad recíproca entre dos especies sintópicas de Byrsonima: B. pachyphylla y B. crassifolia. Se observó el crecimiento del tubo polínico con comportamiento similar en la superficie estigmática, canal del pistilo, ovario y canal micropilar de ambas especies. Además, se describió la autoincompatibilidad parcial en la autopolinización con mayor fructificación en la autogamia. La polinización cruzada y la autopolinización coexisten y se produce una intercompatibilidad recíproca. Los mecanismos de aislamiento precigóticos son improbables por la ausencia de tubos polínicos anormales, producción de frutos y ausencia de híbridos en la área de estudio.","PeriodicalId":53282,"journal":{"name":"Anales de Biologia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47861772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to evaluate the antibacterial and modulatory activities of ethanolic extract of Calotropis procera (Aiton) W.T. Aiton against resistant species. By microdilution method, the minimum inhibitory concentration (MIC) of the extract and modulation of the subinhibitory concentration MIC/8 to norfloxacine, gentamicin and imipenem against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. There was obtained 512 μg/mL to Pseudomonas aeruginosa. To Staphylococcus aureus, modulation showed synergism to norfloxacin and gentamicin, with imipenem against Pseudomonas aeruginosa and gentamicin against Escherichia coli. Based on these results, more studies are needed to test the antibacterial activity of the extract. El objetivo de este estudio fue evaluar la actividad antibacteriana y moduladora del extracto etanólico de Calotropis procera (Aiton) W.T. Aiton contra cepas multirresistentes de bacterias. Por el método de microdilución, fueron definidas la concentración inhibidora mínima (MIC) del extracto y la modulación con la concentración inhibidora CIM / 8 del extracto con norfloxacina, gentamicina e imipenem contra Staphylococcus aureus, Escherichia coli y Pseudomonas aeruginosa. Se obtuvo 512 μg/mL para Pseudomonas aeruginosa. Se descubrió sinergismo en el caso de Staphylococcus aureus, en la modulación con norfloxacina y gentamicina, mientras que con imipenem frente a Pseudomonas aeruginosa y con gentamicina para Escherichia coli. Con base en estos resultados, se necesitan más estudios para probar la actividad antibacteriana del extracto.
