Description
An account of the resource
Objetivo: conocer las características de producción y consumo de cinco cultivos y evaluar la posibilidad de biofortificación como una estrategia viable en una zona rural colombiana. Materiales y métodos: de 60 familias seleccionadas aleatoriamente, se encuestó a la persona encargada de la preparación de alimentos y (si era diferente) a la persona encargada de la producción agrícola acerca de la compra, el consumo y la producción de los cultivos. Resultados: el 100% reportó haber consumido arroz en la última semana, el 96,9% fríjol, el 89,1% yuca, el 81,3% maíz y el 9,4% batata. Los cultivos provenían principalmente de la compra en graneros (fríjol, maíz, arroz) y de la autoproducción (yuca, batata). La yuca fue cultivada por el mayor número de productores (56,6%) seguido por el maíz (46,6%), el fríjol (43,3%) y la batata (16,6%); el arroz no fue producido. Conclusión: sustituyendo la producción con cultivos biofortificados se aportaría, a la dieta, entre 10 y 16% más hierro, zinc y vitamina. Debido a su impacto nutricional potencial, se amerita investigar la adaptabilidad y la aceptabilidad de los cultivos biofortificados en la comunidad.

Description
An account of the resource
Latin American countries show a great potential for expanding their irrigated areas. Irrigation is important for strengthening local and regional economy and for enhancing food security. The present paper aimed at providing a brief review on key aspects of irrigation management in Latin America. Poor irrigation management can have great impact on crop production and on environment while good management reduces the waste of soil and water and help farmers maximizing their profits. It was found that additional research is needed to allow a better understanding of crop water requirements under Latin American conditions as well as to provide farmers with local derived information for irrigation scheduling. The advantages of deficit irrigation practices and the present and future opportunities with the application of remote sensing tools for water management were also considered. It is clear that due to the importance of irrigated agriculture, collaborative work among Latin American researchers and institutions is of paramount importance to face the challenges imposed by a growing population, environment degradation, and competition in the global market.Los países sudamericanos tienen un gran potencial para aumentar sus áreas regadas. El riego es importante para fortalecer las economías locales y regionales y para mejorar la seguridad alimentaria. Esta revisión tiene por objeto proporcionar un resumen de los aspectos más importantes del manejo del riego en Sudamérica. Un manejo pobre del riego puede tener un alto impacto en la producción de cultivos y en el ambiente, en tanto que un buen manejo reduce las pérdidas de suelo y agua, y ayuda a los productores a maximizar sus ingresos. Se encontró que se requiere investigación adicional que permita una mejor comprensión de los requerimientos de agua de los cultivos en las condiciones sudamericanas, y también para proporcionar a los agricultores información local que permita hacer programación de riego. También se consideraron las ventajas del riego deficitario y las oportunidades presentes y futuras de la aplicación de los sensores remotos para el manejo del agua. Está claro que dada la importancia de la agricultura de riego se requiere realizar trabajos colaborativos entre investigadores e instituciones de Sudamérica, para enfrentar los desafíos que imponen el crecimiento de la población, la degradación del ambiente y la competencia en los mercados globales.

Description
An account of the resource
Se ofrecen aspectos de la biología y ecología de las formas adultas de Anastrepha obliqua, en condiciones de laboratorio y de campo. La emergencia de las formas adultas ocurrió entre 11 y 22 días con un promedio de 17 días. En el campo, la humedad relativa atmosférica parece ser el principal factor determinante de la emergencia de los adultos. Hongos y parasitoides determinan que un porcentaje de pupas quede sin emerger, pero otra fracción emergerá en los meses subsiguientes en pequeños grupos. El agua constituyó un factor de mortalidad en la cría masiva de esta especie, dada la facilidad con que mueren por ahogamiento. Las arañas constituyen otro factor de mortalidad bajo cría masiva. Los adultos de A. obliqua demuestran un comportamiento de polifagismo en su alimentación. La madurez sexual se determinó en 17 días. La longevidad máxima varió de 40 a 53 días siendo la tasa de sobrevivencia entre ambos sexos bastante similar. La longevidad, bajo condiciones de laboratorio, parece depender del tipo de dieta larval y del adulto. La esperanza de vida media fue de 29 días para machos y 31,5 días para las hembras. Adultos marcados y liberados en el campo fueron recapturados 58 días después siendo su longevidad mayor a la del laboratorio. En condiciones de cautividad el cortejo de los adultos parece ser ignorado y la cópula ocurre sin complicaciones, con una duración aproximada de 45 minutos.

Description
An account of the resource
La producción sostenible de granos como el maíz es de prioridad nacional y mundial para salvaguardar la seguridad alimentaria y el ambiente, los cuales están en controversia por encontrar un equilibrio, la productividad versus la contaminación generada. El objetivo fue evaluar el efecto de abonos orgánicos (AO) y la fertilización mineral convencional (FQ) sobre la eficiencia de uso del N en el cultivo de maíz. En el Centro Universitario Regional del Litoral Atlántico (CURLA), Honduras, se sembró maíz variedad Tuxpeño, entre los meses de junio a diciembre del 2015. El diseño experimental fue de bloques completos al azar con cinco tratamientos y cuatro repeticiones. En diferentes etapas fenológicas del cultivo se evaluaron en el suelo: N total, amonio, nitrato, temperatura, humedad volumétrica; en la planta se evaluó: N, rendimiento en grano seco y la eficiencia de uso de nutrientes para N se evaluó en términos de la eficiencia agronómica (EA), eficiencia fisiológica (EF) y eficiencia de recuperación (ER). La FQ y los AO generaron cambios relevantes en la dinámica del N en suelo y planta, la fertilización mineral promovió una mayor eficiencia de uso de nitrógeno en maíz, a través de los indicadores de la eficiencia agronómica, la eficiencia de recuperación y el rendimiento de grano.

Description
An account of the resource
The cephalochordates are represented by the lancelets, of which species of the genus Branchiostoma are the best known. In recent years, these organisms have been the center of activity of studies focusing on the phylogenetic relationships of the chordates. In 1980, a survey of the benthos at 48 stations in the Gulf of Nicoya estuary, Pacific coast of Costa Rica, yielded 265 specimens of the lancelet Branchiostoma californiense. A total of 48 specimens was also collected at an intertidal flat in the mid upper estuary. Of the 48 subtidal stations, only eight had B. californiense, and these sites all had a sand fraction above 72%. The remaining stations ranged in their sand content from as low as 1% to as high as 92%, with an average of 25.9%, with 29 stations having a sand content lower than 72%. Lower salinities and muddy sediments may limit the distribution of the lancelet further upstream. This information is useful when changes over decades in the ecology of the estuary need to be evaluated against the background of local, regional, and global dynamics. Rev. Biol. Trop. 58 (4): 1143-1148. Epub 2010 December 01.Los cefalocordados están representados por los anfioxos, de los que especies del género Branchiostoma son los más conocidos. En los últimos años, estos organismos han sido muy estudiados, principalmente sus relaciones filogenéticas. Durante 1980, realizamos un muestreo del bentos en 48 estaciones del Golfo de Nicoya, costa Pacífica de Costa Rica y reportamos 265 ejemplares del anfioxo, Branchiostoma californiense. También recolectamos un total de 48 individuos en una planicie fangosa de la zona entre mareas de la región superior media del estuario. De las 48 estaciones solamente en ocho encontramos especímenes de B. californiense y estos sitios tenían un porcentaje de arena superior al 72%. Las otras estaciones tenían un porcentaje de arena en un ámbito tan bajo como 1% y tan alto como 92%, con un promedio de 25.9%, 29 estaciones presentaron un porcentaje de arena menor de 72%. Salinidades bajas y sedimentos fangosos pueden limitar la distribución del anfioxo en la región superior del estuario. Esta información es de utilidad cuando se desea evaluar los cambios en la biodiversidad y la ecología del estuario a largo plazo en el contexto de la dinámica local, regional o global.

Description
An account of the resource
The palm genus Astrocaryum with 40 species is common in tropical South America extending northwards reaching Central America and Trinidad. Twenty-six species grow in Brazil, 14 in Peru, 11 in Colombia, 9 in Guyana, 9 in Suriname, 8 in Bolivia, 8 in French Guiana, 6 in Venezuela, 4 in Ecuador, 2 in Costa Rica, 2 in Panama, and 1 in Trinidad. The genus includes solitary or caespitose species in the following classes: (i) large palms with tall stem, (ii) palms with large leaves and medium-sized, or short, or subterranean stem, (iii) slender to mediumsized palms, (iv) acaulescent palms with very short leaves. Although most Astrocaryum species are used by humans, only a few may have promising economic potential and are significantly important in the local and regional trade. In this article, I propose a new taxonomic classification based on characters of the fruit, flowers and vegetative parts. The genus is divided in three subgenera: (i) Munbaca with two sections, Munbaca and Mumbacusu, each with 2 species; (ii) Astrocaryum with two sections, Euchambira (new section with 1 species) and Astrocaryum with three subsections — Astrocaryum (9 species), Acaulia (5 species) and Perstaminata (new subsection with 1 species); (iii) Monogynanthus with four sections: Monogynanthus (with 3 species), Ayri (1 species), Guatinajo (new section with 1 species) and Huicungo (new section) that includes three subsections — Huicungo (7 species); Sachacungo (new subsection with 5 species), and Murumuru (3 species). A synoptic review of the genus is presented herein, including descriptions and illustrations as well as data on distribution, habit, ecology and common names for each species. An identification key to all species is also supplied.

Description
An account of the resource
En los actuales momentos de crisis ambiental y social se requiere una respuesta integrada, a escala supranacional, planetaria incluso, cuyo reto principal es pasar de una mentalidad antropocéntrica a otra ecocéntrica, que respete y preserve la Naturaleza. Este impulso debe venir guiado por diversas corrientes sociales y de pensamiento. La lectura, en esta orientación, es un arma estratégica: su cometido es (re)signigicar la realidad, dando un significado renovado a todo lo que venimos categorizando como lecturas naturistas. Se revisa, pues, la incidencia del giro antológico en el abordaje de las lecturas de la naturaleza y el papel de las nuevas narrativas del agua. En el ámbito de intervención didáctica, se proponen criterios y buenas prácticas de intervención, basadas en tres pilares: promover la cultura vernácula del agua, fomentar programas de sensibilización y utilizar las propuestas ecofeministas.

Description
An account of the resource
In this study the structure and diversity of the endohelminth community, as well as its interactions with 73 specimens of Piaractus mesopotamicus are described. The fish were caught in Aquidauana and Miranda rivers, both located in the Pantantal region, in the state of Mato Grosso do Sul. A total of 608,788 specimens of helminthes were found, representing five species: Dadaytrema oxycephala, Chabaudinema americanum, Spectatus spectatus, Rondonia rondoni and Echinorhynchus jucundum. D. oxycephala was more prevalent (91.78%) followed by R. rondoni (73.97%). Simpson's index indicated dominance in the endohelminth infracommunities (C = 0.396) and D. oxycephala was considered central species. A total of 54 hosts had between 2 and 3 species of helminthes. The pairs of the species R. rondoni/D. oxycephala and S. spectatus/D. oxycephala showed significant positive correlation between abundances. There was a significant positive correlation between total length and abundance of S. spectatus (rs = -0.2467 and p = 0.0353). Abundance of R. rondoni between the periods of 1/2003 and 2/2003 (p = 0.0356) and 1/2003 and 4/2004 (p = 0.0009) was significantly different. There was significant prevalence of E. jucundum in the female hosts.Neste trabalho, foram descritas a estrutura e a diversidade da comunidade endo-helmíntica de 73 exemplares de Piaractus mesopotamicus e suas interações com os hospedeiros, capturados nos rios Aquidauana e Miranda, MS. Foram encontrados 608.788 espécimes de helmintos, representados por cinco espécies: Dadaytrema oxycephala, Chabaudinema americanum, Spectatus spectatus, Rondonia rondoni e Echinorhynchus jucundum. O digenético D. oxycephala foi a espécie mais prevalente, com 91,78%, seguido do nematoda R. rondoni com 73,97%. O índice de Simpson indicou dominância entre as infracomunidades de endo-helmintos (C = 0,396), sendo D. oxycephala a espécie dominante. Dos hospedeiros amostrados, 54 continham entre duas e três espécies de endo-helmintos. Os pares R. rondoni/D. oxycephala e S. spectatus/D. oxycephala apresentaram correlações positivas significativas entre as abundâncias. Correlação positiva significativa foi observada entre comprimento total e abundância parasitária para S. spectatus (rs = - 0,2467 e p = 0,0353). A abundância de R. rondoni foi diferente estatisticamente entre o período 1/2003 e 2/2003 (p = 0,0356) e o período 1/2003 e 4/2004 (p = 0,0009). A prevalência de E. jucundum foi maior significativamente nas fêmeas.

Description
An account of the resource
De março/1988 a julho/1990, em 14 ocasiões, foram coletadas 410 amostras de solo de rizosfera de plantas do litoral arenoso da Ilha do Cardoso, SP, Brasil, com finalidade de se conhecer a micota de fMA. Foram investigadas as rizosferas das plantas: Baccharis trimera DC., Blutaparon portulacoides (St. Hil.) Mears, Dalbergia hecastaphylla (L.) Taub., Hydrocotyle bonariensis Lam., Ipomoea pes-caprae (L.) Swett e Polygala cyparisseas St. Hil. & Moq. Verificaram-se 24 espécies de fMA. Os resultados obtidos permitiram constatar que: a) há tendência em ter-se aumento no número de esporos no solo com o aumento da temperatura, precipitação e insolação; b) diferentes espécies de fMA ocorrem em diferentes espécies de plantas hospedeiras, sugerindo a existência de especificidade ecológica; c) há maior abundância de esporos das espécies de Acaulospora, Gigaspora e Scutellospora sobre as de Glomus. Não se verificou relação entre a fenologia das plantas hospedeiras, o número de esporos no solo e a porcentagem de colonização das raízes.From March/1988 to July/1990, in 14 opportunities, it was collected 410 soil samples of rhizospheres of native plants from sandy soils of Ilha do Cardoso, SP, Brazil to investigate the occurrence of AM fungi. The studied plants were: Baccharis trimera DC., Blutaparon portulacoides (St. Hil.) Mears, Dalbergia hecastaphylla (L.) Taub., Hydrocotyle bonariensis Lam., Ipomoea pes-caprae (L.) Swett and Polygala cyparisseas St. Hil. It was observed 24 species of AM fungi. The results showed: a) a tendency to increase the number of spores in the soil with the increase of the temperature, rainfall and sunlight; b) different species of AM fungi occurred in different species of hosts, suggesting ecological specificity of AM fungi; c) it was observed higher abundance of spores of Acaulospora, Gigaspora and Scutellospora over spores of Glomus and Sclerocystis. It was not observed relatonships between the number of spores in the soil, taxa of colonization of the roots and the fenology of hosts plants.
