Title A name given to the resource Observaciones sobre la ecología del páramo andino de Monserrate Observaciones sobre la ecología del páramo andino de Monserrate Creator An entity primarily responsible for making the resource Sturm Helmut, Abouchaar Alberto Description An account of the resource In a paramo region near Bogotá (Colombia), 3.230 m aboveseal evel investigations were made of clima, soil vegetation and fauna. The mean temperature was 8.4 degrees C and the annual rainfall 1.221.4 mm. Sometimes great variations of relative humidity and of temperature near the soil surface could be registered. The properties of the black coloured paramosoil, wich probably is not a uniform type, are discussed. Its micromorphology and fauna were examined for the first time. The fauna is well developed and takes part intensivily in mixing the mineral and organic components. The soil type is classified as being between those which KUBIENA (1953) called 'Pechtorf' and 'Moderranker', The vegetation has been characterized by the estimation of the 'Artmächtigkeit' (BRAUN-BLANQUET,1964) of the single species. The distribution and net production of Espeletia grandiflora Humb. & Bonpl., the most specificplant species in this paramo is discussed. The quantitative sampling of the fauna, especially of the arthropod fauna,was carried out by means of a combination of different methods to evaluate the density per litre and the density of activity. The mantle consisting of dead leaves of E. grandiflora proved to be a rich and characteristic 'biotope'. The facts are discussed partly by comparing them with correspondingfacts from a tropical rain forest.In a paramo region near Bogotá (Colombia), 3.230 m above seal evel investigations were made of clima, soil vegetation and fauna.

Title A name given to the resource Inseguridad alimentaria en latinos de California: observaciones de grupos focales Creator An entity primarily responsible for making the resource Melgar-Quinonez Hugo, Kaiser Lucía L, Martin Anna C, Metz Dianne, Olivares Anna Description An account of the resource OBJETIVO: Estudiar la percepción y la experiencia sobre inseguridad alimentaria entre latinoamericanos de California, así como su interpretación de los insumos incluidos en la Escala de Seguridad Alimentaria. MATERIAL Y MÉTODOS: Entre noviembre y diciembre de 2000, en los condados californianos de Solano y San Joaquín, se efectuaron cuatro grupos focales, con 30 adultos de origen latinoamericano residentes allí. Los comentarios de los participantes fueron codificados por dos investigadores para determinar los temas principales, y fueron confrontados para verificar su convergencia. RESULTADOS: Las preguntas fueron bien comprendidas, no percibiéndose como ofensivas. El marco conceptual se confirmó como 'proceso manejado' con diferentes niveles de severidad. Las causas de inseguridad alimentaria identificadas fueron: desempleo, alto costo de algunos alimentos y falta de información nutricional. La necesidad de educación nutricional fue una constante. CONCLUSIONES: Para interpretar datos nacionales de inseguridad alimentaria en latinoamericanos es esencial considerar su percepción particular de ese fenómeno.

Se desplaza en el sotobosque lleno de epífitas, dependiendo parcialmente de los insectos que huyen de los escasos ejércitos de hormigas. Es un ave silenciosa y arisca, que se esconde después de volar cortas distancias en busca de presas, o procurándolas en musgos o troncos. La pérdida de los bosques húmedos andinos de laderas abruptas para dar lugar a la ganadería de baja productividad amenaza a la especie y aumenta el peligro de derrumbes en áreas sujetos a temblores; el uso más apropiado para tales áreas es para estudios científicos y actividades turísticas, y no para asentamientos permanentesThe Tyrannine Woodcreeper (Dendrocincla tyrannina, Dendrocolaptidae) of northern Andean cloud forests is solitary, like the rest of the genus, and wanders in the epiphyte-laden forest understory, depending partly on hard-to-find swarms of army ants and on understory flocks to flush insects. It is wary and silent, hiding after flying short distan ces for prey or gleaning it from moss or trunks. As los s of sleep Andean wet forests where the woodcreepers live resulls in gretaer danger from earthquakes, study and tourism are preferable to settlements.

Title A name given to the resource Seed germination and removal of Michelia champaca L. (Magnoliaceae) in eucalypt stands: the influence of the aril Germinação e remoção de sementes de Michelia champaca L. (Magnoliaceae) em talhões de eucalipto: influência do arilo Creator An entity primarily responsible for making the resource Giovano Candiani, Mauro Galetti, Victor Jose Mendes Cardoso Description An account of the resource We tested the influence of the aril on seed germination in controlled conditions and on the removal of M. champaca seeds in natural environment. Germination assays were kept at 25 ± 2 °C under continuous white light. Removal experiments were carried out in three 'old' (39 to 62-years old) and three 'new' (15-years old) eucalypt stands in Horto Florestal Navarro de Andrade, Rio Claro, SP. The results show that the aril inhibits the germination and the seeds exhibit a positively photoblastic reaction. We found higher seed removal in old eucalypt stands than the new ones, probably due to the higher density of rodents in the old stands. In the new stands, we found higher seed removal of arillated seeds by ants. Ants are important to remove the aril of seeds dropped by birds, not only enhancing seed germination but also preventing seed predation by rodents.Testou-se o efeito do arilo na germinação de M. champaca em condições controladas, bem como na sua remoção, em ambiente natural. Os ensaios de germinação foram mantidos a 25 ± 2 °C, sob luz branca constante. Os experimentos de remoção foram levados a cabo em três talhões 'velhos (idades de 39 a 62 anos) e três 'novos' (15 anos de idade) de eucalipto mantidos no Horto Florestal Navarro de Andrade, em Rio Claro, SP. Os resultados indicaram que o arilo inibe a germinação, sendo as sementes fotoblásticas positivas. Observou-se que a remoção de sementes foi maior em talhões 'velhos' do que em 'novos', provavelmente devido à maior densidade de roedores nos talhões velhos. Nos talhões novos, verificou-se que formigas removiam mais sementes ariladas. Esses insetos são importantes agentes na remoção do arilo de sementes derrubadas por pássaros, promovendo, assim, aumento na germinação e evitando a possível predação das sementes por roedores.

Title A name given to the resource Caracterización parcial de los contratistas de servicios de maquinaria agrícola en la micro región 2 '“provincia de La Pampa, Argentina Creator An entity primarily responsible for making the resource Soledad Stadler, Guido Fernando Botta Description An account of the resource La introducción de nuevas tecnologías como la siembra directa y las semillas transgénicas, han ocasionado notables cambios en los aspectos productivos, económicos, sociales y ambientales. En este contexto, la figura del contratista de servicios de maquinaria agrícola, aumentó notablemente su participación en las actividades agrícolas, no solo en la región pampeana, sino también en las regiones extrapampeanas como consecuencia del corrimiento de la frontera agrícola. En la provincia de La Pampa, estos contratistas participan activamente en el proceso productivo agrícola. Sin embargo, más allá de los datos provenientes de los censos nacionales agropecuarios - que actualmente resultan obsoletos -, son escasos los estudios empíricos que muestran la realidad e importancia de este actor social. El objetivo del presente trabajo es caracterizar la relevancia socio-económica, tecnológica y productiva de los contratistas de servicios de maquinaria agrícola que residen en las localidades del sur de la micro-región 2 de la provincia de La Pampa. La estrategia metodológica está basada en el análisis de la información primaria generada a partir de encuestas realizadas a 31 contratistas que conforman una muestra del universo de estudio. Los principales resultados muestran una heterogeneidad de escalas de trabajo, clientes y servicios ofrecidos.

Title A name given to the resource ORGANIC FERTILIZER AS PHOSPHORUS SUPPLIER FOR Brachiaria brizantha CV. MARANDÚ FERTILIZANTE ORGÂNICO COMO FONTE DE FÓSFORO NO CULTIVO INICIAL DE Brachiaria brizantha CV. MARANDÚ Creator An entity primarily responsible for making the resource Carlos Sérgio Tiritan, Gustavo Maia Souza, Diego Henriques Santos, Ornã Enisson Almeida Ourives Description An account of the resource  Phosphorus is considered an essential element for plants, but it is found in low amounts in Brazilian soils, mainly in areas destined to pastures, and the application of organic matter contributes to the improvement of physical, chemical and biological soil attributes. The research had the objective of evaluating the application effects of the Bokashi organic compound on soil macro and micronutrients contents and leaves, as well as on Brachiaria brizantha cv. Marandú dry mass yield, evaluating the potential of the organic fertilizer as phosphorus source, in comparison with conventional chemical fertilizers. Different organic compound doses supplied the soil with 17 kg P2O5 ha-1, 34 kg P2O5 ha-1, 68 kg P2O5 ha-1, 136 kg P2O5 ha-1, and 204 kg P2O5 ha-1, comparing it with the conventional chemical fertilizer and the control. The results revealed that the organic fertilizer Bokashi can adequately replace the conventional chemical fertilizer of Brachiaria brizantha cv. Marandú, supplying the soil and plant with appropriate nutrients levels and maintaining the dry mass yield. KEY-WORDS: Organic matter; organic fertilizers; plants mineral nutrition; Bokashi.  O fósforo é considerado elemento essencial para as plantas, mas é encontrado em baixas quantidades nos solos brasileiros, principalmente em áreas destinadas a pastagens, e a aplicação de matéria orgânica contribui para a melhoria dos atributos físicos, químicos e biológicos do solo. O trabalho teve por objetivo avaliar os efeitos da aplicação do composto orgânico Bokashi sobre os teores de macro e micronutrientes do solo e nas folhas, além da produção de massa seca da Brachiaria brizantha cv. Marandú, avaliando o potencial do adubo orgânico como fonte de fósforo, em comparação à adubação química convencional. Foram aplicadas diferentes doses do composto orgânico, fornecendo ao solo 17 kg P2O5 ha-1, 34 kg P2O5 ha-1, 68 kg P2O5 ha-1, 136 kg P2O5 ha-1 e 204 kg P2O5 ha-1, comparando-o com a adubação química convencional e o tratamento testemunha. Os resultados revelaram que o adubo orgânico Bokashi pode substituir, de forma viável, a adubação química convencional da Brachiaria brizantha cv. Marandú, suprindo o solo e a planta com níveis adequados de nutrientes e mantendo a produção de massa seca. PALAVRAS-CHAVE: Matéria orgânica; adubação orgânica; nutrição mineral de plantas; Bokashi.

Title A name given to the resource Estimation of the structural stability of two soils of the south of Colombia with different types of management. Estimación de la estabilidad estructural de dos suelos al sur de Colombia con diferentes tipos de manejo. Creator An entity primarily responsible for making the resource Carrillo Jesús, Navia Jorge, Menjivar Juan Carlos Description An account of the resource The study carried out in two localities in zones to the north of the department of the Cauca Colombia, random a design of blocks with six treatments was used: 1. bare plots (reference); 2. Rotation crops + organic fertilizer. (Farming); 3. Rotation from improved praire. (Minimum till + chemical fertilizer); 4. Conventional rotation. (Chemical Farming + chemical fertilizer); 5. Rotation crops + legumes. (Chemical Farming + chemical fertilizer); 6. Rotation from improved praire. (Chemical Farming + chemical fertilizer). These treatments established as run–off plots during eight years were exposed without vegetation to the impact of rains during 10 months, which were compared to the reference plots whose original to praire was 15 years old. To evaluate the structural stability the test of turbidimetría was used. The results appeared like the area under the curve (AUC) for the dispersion variable (%), which was lower for the aggregates taken from the surface of virgin soils (Treatment 1) and rotation of crops plus minimum till (Treatment 3). The rotation treatment with addition of organic chicken manure (3 t/ha) and covers of legumes presented the higher values.En el estudio que se realizó en dos localidades de la zona de ladera al norte del departamento del Cauca, Colombia, se utilizó un diseño de bloques al azar con seis tratamientos: 1. Parcelas descubiertas (referencia), 2. Rotación cultivos + abono orgánico (labranza); 3. Rotación a partir de pradera mejorada (labranza mínima + abono químico); 4. Rotación convencional (labranza + abono químico); 5. Rotación cultivos + leguminosas (labranza + abono químico); 6. Rotación a partir de pradera mejorada (labranza + abono químico). Los tratamientos se establecieron como parcelas de escorrentía durante ocho años y luego se sometieron sin vegetación a la exposición de las lluvias durante 10 meses y se compararon con las parcelas de referencia que habían estado cubiertas por pradera nativa durante 15 años. Para evaluar la estabilidad estructural se utilizó la prueba de turbidimetría y los resultados se presentaron como el área bajo la curva (ABC) para la variable dispersión (%), la cual fue más baja para los agregados tomados de la superficie de suelo virgen (Tratamiento 1) y de rotación de cultivos más labranza mínima (Tratamiento 3). Los tratamientos de rotación con adición de abono orgánico (gallinaza 3 t/ha) y coberturas de leguminosas presentaron valores más altos.

Title A name given to the resource La nueva ruralidad en México Creator An entity primarily responsible for making the resource Javier Delgado Campos Description An account of the resource En los paises desarrollados, la ocupación de áreas rurales tradicionales por actividades modernas, industriales o urbanas, hacen que la actividad agropecuaria sea sólo una, y no la más importante, de la vida rural, esto ha sido denominado como 'nueva ruralidad' o 'rurbanización'(Bertrand et al., 1987; Garcia, 1996).México parece ir en la misma dirección que los países desarrollados, lo mismo en el surgimiento reciente de la llamada 'agricultura periurbana' cuyo éxto estriba en nuevas técnicas productivas (Lara, 1996; Arias, 1992), como en el reagrupamiento diferenciadode regiones de producción y consumo que aislan al resto de las regiones (Delgadillo, 1993), de forma simultánea a la reestructuración socioespacial del sistema urbano nacional (Aguilar y Rodríguez, 1996). En conjunto, se verifica la persistencia de la ruralidad, lo que configura una tendencia hacia el mantenimiento y la profundización de las desigualdades entre el centro yuna periferia rural-regional cada vez más amplia. Por ello, el principal objetivo del documento es presentar una lectura critica de algunos de los trabajos publicados recientemente, en México o en el extranjero, acerca de esta nueva configuración del espacioagricola en nuestro país.

Title A name given to the resource Gestión del conocimiento sustentable universitario Visión aproximada de experiencias latinoamericanas Creator An entity primarily responsible for making the resource Beatriz Carolina Carvajal Description An account of the resource En la investigación que sustenta este artículo, se desarrolló como objetivo: el análisis de experiencias de gestión de conocimiento en universidades latinoamericanas (Venezuela, Argentina, Brasil). Con base en ese análisis, se plantearon lineamientos generales para la gestión del conocimiento sustentable. Se propone el concepto de gestión del conocimiento sustentable como abstracción teórica, que permite la conexión tanto del constructo de co-inspiración (Maturana, 1997a, 1997b) como del criterio de autopoiesis (Maturana y Valera, 1999), con el principio de una mente sustentable (Vieira, 2011). Desde una perspectiva transdisciplinar en la que convergen: la sociología, la biología y la ecología, la problemática de la gestión de conocimiento es vista como una articulación de procesos sociales y ecológicos, que pueden ser comprendidos con la mediación de diversas disciplinas que posibilitarían la gestión del conocimiento a futuro. Los lineamientos generales postulados se fundan en la reflexión teórica y en la interpretación de las entrevistas semiestructuradas a expertos en el área de gestión de conocimiento de las universidades seleccionadas en el muestreo intencional, a saber: a) en Venezuela: Universidad Centroccidental Lisandro Alvarado (UCLA), Universidad del Zulia (LUZ), Universidad Nacional Experimental Rafael María Baralt (UNERMB), y la Universidad de Carabobo (UC); b) en Argentina: Universidad de Buenos Aires y Universidad de Córdoba, y c) en Brasil: Instituto Federal Sul Rio Grandense y la Universidad Federal de Río de Janeiro (UFRJ). Se concluye que la producción y la gestión del conocimiento académico sustentable han sido importantes inquietudes históricas de los académicos latinoamericanos; se agrega que esos problemas tienen expresiones específicas en los diferentes países. Factores de orden socioeconómico, político y ecológico, tales como pobreza, hambre, desigual distribución del ingreso global, indisponibilidad de recursos médicos y biotecnológicos y daño ecológico, sólo por mencionar algunos, representan una realidad que impulsa a los académicos hacia la búsqueda de respuestas decisivas, planteando la urgencia en la búsqueda de la renovación en la gestión del conocimiento universitario. La propuesta es hacer coexistir, como igualmente importantes y sin subordinación el uno del otro, dos focos de referencia: la organización universitaria como un todo y cada una de las personas que la constituyen; una gestión precedida por la inter- y transdisciplinariedad del conocimiento, y sostenida en una red conversacional de comprensión, inclusión, y co-inspiración.
