Title A name given to the resource Phytoplankton Ecology and Hydrological Dynamics of the Yahuarcaca Lake System, Amazonas, Colombia: Integrated Analysis of 16 Years of Study Creator An entity primarily responsible for making the resource SANTIAGO R. DUQUE, Maria Juliana Salcedo-Hernández, Liliana Palma, Angélica Torres-Bejarano, Diego Montenegro, Nixon Bahamón, Luisa Lagos, Luis Fernando Alvarado, Marta Gómez, Angela Patricia Alba Description An account of the resource This article provides a synthesis of the current knowledge on the evolving relation between the Amazon River and the Yahuarcaca lagoon system, through the limnological features and the ecology of phytoplankton in a period of sixteen years. The synthesis of the information was conducted by reviewing existing data about the system, for the time indicated, and analyzing it by means of descriptive statistics and linear correlation between the variables found. Also, it contains a summary of the most important aspects of the first attempt in Colombia to evaluate the influence of the flood pulse on the phytoplankton in a daily time scale. The thermal pattern of this laggon system corresponds to a warm and constant polymicthic lake type according to the de Lewis (1983) classification. The physical, chemical and biological variables examined in this várzea system change according to the hydrologic period. The conductivity, transparency and richness of the phytoplankton increase in the low water season, while the nutrient concentration, and the density, productivity and the biomass of phytoplankton increase during the high water season. Nitrate during the low water season and phosphate during the high water season are the most restricting nutrients. The changes that have taken place through these years in the connectivity between the river and the Yahuarcaca lagoon system are reflected in the dynamics of the structure and composition of the phytoplankton.

Title A name given to the resource EFECTO DE UN FOSFATO TÉRMICO SOBRE EL CRECIMIENTO Y PRODUCCIÓN DE FRÍJOL (Phaseolus vulgaris L.) CV ICA CERINZA Creator An entity primarily responsible for making the resource Elberth Hernando Pinzón Sandoval, Wilmer Alejandro Quintana Blanco, David Fernando Torres Description An account of the resource El fríjol es la leguminosa más importante del mundo por su aporte a la seguridad alimentaria y por el alto contenido de proteínas y de minerales esenciales. En américa latina y especialmente en Colombia, el cultivo de fríjol es importante en la economía campesina, pero, en la actualidad, la producción no satisface la demanda, haciendo necesario importar este producto. En la zona ecuatorial y subecuatorial, los suelos, en su mayoría, presentan condiciones ácidas, que conlleva a una baja fertilidad y limitación en la toma de elementos, como el fósforo. Por esto, el uso de fuentes de fósforo no convencionales representa una alternativa en la disponibilidad de este elemento, que mejore la dinámica nutricional y así generar un buen crecimiento y producción de los cultivos. El objetivo de esta investigación fue evaluar el efecto de un fosfato térmico sobre el crecimiento y el rendimiento del cultivar de fríjol 'ICA Cerinza', bajo condiciones agroecológicas, del municipio de Tunja-Boyacá. Se empleó un diseño completamente al azar, con cuatro tratamientos correspondientes a dosis de fosfato térmico 0, 300, 600 y 900kg ha-1, con cuatro replicaciones. Se evaluó el contenido total de clorofila, área foliar, peso seco de órganos, numero de vainas por planta y granos por vaina, peso de cien granos, rendimiento y contenido foliar de fósforo. Se presentaron diferencias estadísticas entre tratamientos (P≤0,05), para las variables de crecimiento y el número de vainas por planta. La aplicación de 600kg ha-1 de fosfato térmico mostró los mejores resultados, posiblemente, debido a las características del producto, tales como solubilidad y composición, siendo una alternativa en suelos de condiciones moderadamente ácidas.

Neste horizonte se inscrevem as questões atinentes à moléstia de Chagas especialmente no âmbito das ações de controle dirigidas aos triatomíneos, a luta antivetorial , a qual permanece, mesmo após quase um século de sua descrição por Carlos Chagas, como uma condição de grande impacto epidemiológico na América Latina. Com base nestas considerações, o presente artigo buscará discutir os principais aspectos ecológicos relacionados à tripanossomíase americana em um esforço de delimitação da questão, muito mais do que proposição de respostas , enfatizando-se o controle da transmissão vetorial, repensada em termos da ecologia profunda.The inter-relations between man and the environment are among the main themes currently debated by the Brazilian public health. On such horizon, the questions concerning Chagas's disease are found to remain specially in the scope of the directed actions of control to the triatomine, the anti-vectorial fight , though already a century since its first description by Carlos Chagas, a major epidemiological problem in Latin America. Based on these considerations the present article will seek to discuss the main ecological aspects related to the American trypanosomiasis, emphasizing the control of the vectorial transmission in the context of the deep ecology.

De esta forma, existe desconocimiento acerca de la ecología de las epífitas en matorrales xeromorfos espinosos sobre serpentina. Estos ecosistemas constituyen sitios de gran importancia por su riqueza florística y alto endemismo. En este estudio se caracterizó la composición de la sinusia de epífitas vasculares y se evalúo la influencia de las variables del microhábitat sobre su abundancia en el cuabal Lomas de Galindo. La sinusia de epífitas estuvo representada por cuatro especies de Tillandsia, con dominancia numérica de T. recurvata. Todas resultaron holoepífitas y no evidenciaron especificidad entre las especies utilizadas como forófito. El área del forófito y el diámetro de la copa mostraron los mayores valores de correlación con el número de individuos epífitos. La distribución horizontal de las epífitas sobre el forófito mostró mayor afinidad de estas por las ramas internas, debido a su mayor grosor y a las más drásticas condiciones actuantes sobre las ramas externas. Sin embargo, la distribución vertical no evidenció un patrón de segregación entre las especies, probablemente debido al estrecho gradiente microclimático vertical que caracteriza las formaciones arbustivas. Palabras clave: ecosistemas serpentinícolas, forófito, Tillandsia Epiphytism lifestyle constitutes 5% of Cuban vascular flora and microhabitat requirements studies by epiphytes have been made in forest ecosystems. Thus, there is poor knwledge about the ecology of epiphytes in xeromorphic thorn scrub on serpentine. These ecosystems are sites of great importance for its floristic richness and high endemism. In this study the composition of the synusia of vascular epiphytes was characterized and influence of microhabitat on abundance was evaluated in the Lomas de Galindo cuabal. The epiphytic synusia was represented by four species of Tillandsia, with numerical dominance of T. recurvata. All were holoepiphytes and showed no specificity between the species used as phorophyte. However, the area of phorophyte and crown diameter showed the highest values of correlation with the number of epiphytic individuals. The  horizontal distribution of epiphytic on phorophyte showed higher affinity for these internal branches, due to its greater thickness and to the most drastic you condition on the external branches. Nevertheless, the vertical distribution did not show a pattern of segregation among species, probably due to the narrow vertical gradient microclimate that characterizes the shrub formations.

Sánchez Rendón, Justo L. González Description An account of the resource RESUMEN Spirotecoma holguinensis es una especie pionera endémica que crece en los matorrales xeromorfos espinosos sobre serpentina de la provincia Holguín, Cuba. Con el objetivo de contribuir a la conservación de S. holguinensis se caracterizaron rasgos morfológicos de sus semillas, requerimientos germinativos, tolerancia a la desecación y tipo funcional de plántula. La germinación se evaluó a una temperatura fija y cuatro termoperiodos (25ºC, 25ºC/30ºC, 25ºC/35ºC, 25ºC/40ºC y 25ºC/45ºC), con dos condiciones de iluminación (luz y oscuridad). La especie posee frutos secos, de tipo silicua dehiscente, con semillas aladas, 97 por fruto como promedio. Las semillas son pequeñas con masa fresca y seca de 3,4 y 3,1 mg, respectivamente, y un contenido de humedad inicial de 9,28%. El embrión es desarrollado, de tipo axial invertido y la relación embrión/semilla alcanzó un valor de 0,95. Además, las semillas destinaron 67,7% de su masa a la formación de estructuras de reserva. La especie no presentó dormancia seminal y las semillas son fotoblásticas indiferentes, aunque la mejor respuesta germinativa se obtuvo a la luz a 25ºC/30ºC. Al aumentar la temperatura del sustrato la velocidad de germinación disminuyó. Las semillas se comportaron como tolerantes a la desecación y las plántulas se clasificaron como fanerocotilar epigea con cotiledones foliáceos. Se discute el papel ecológico de los rasgos de historia de vida identificados en S. holguinensis y su relación con otros árboles tropicales pioneros. Palabras claves: planta tropical pionera, ecología de semilla, temperatura, fotoblastismo ABSTRACT Spirotecoma holguinensis is a endemic pioneer species that grow in serpentine xeromorphic thorny scrub of Holguin, Cuba. In order to contribute to the conservation of S. holguinensis, morphological features of its seeds, germination requirements, desiccation tolerance and seedling functional type were characterized. Germination was assessed in a constant temperature and four thermoperiods (25ºC, 25ºC/30ºC, 25ºC/35ºC, 25ºC/40ºC and 25ºC/45ºC) with two light conditions (light and dark) experiments. The fruits were a dry dehiscent silique, with winged seeds and an average of 97 seeds per fruit. The seeds were small, with fresh and dry weight of 3.4 and 3.1 mg, respectively, and with an initial moisture content of 9.28%. The embryo was developed, axial inverted type and ratio embryo: seed was higher than 0.95, so that embryo occupied 95% of the seed cavity. The seeds allocated 67.7% of its mass to the formation of reserve structures. The species did not present dormancy and seeds were photoblastic indifferent, although the best germination was obtained to light on 25ºC/30ºC. By increasing the substrate temperature, germination rate decreased. The seeds were desiccation tolerant and seedlings were classified as phanerocotylar epigeal with foliaceous cotyledons. We discussed the ecological role of the life history traits identified in S. holguinensis and its relationship with other pioneers tropical trees.
