In northeastern Argentina, very little is known about the impact of various techniques of management of residues from forest harvesting on soil properties. We carried out this study in two sites in Entre Ríos Province (Argentina): post-harvest of Eucalyptus grandis Hill ex Maiden stands in an Aquic Hapludert (S1) and in a Fluventic Hapludoll (S2)....

ContextAmphibians are declining worldwide and land use change to agriculture is recognized as a leading cause. Argentina is undergoing an agriculturalization process with rapid changes in landscape structure. Objectives We evaluated anuran response to landscape composition and configuration in two landscapes of east-central Argentina with different...

Anastrepha fraterculus (Diptera: Tephritidae) and Ceratitis capitata (Diptera: Tephritidae) are fruit fly pests whose larvae are frequently found sharing the same fruit with conspecifics. Because larvae are incapable of leaving the fruit in search of non‐infested fruit, they are forced to share nutritional resources and eventually compete with othe...

Silvicultural treatments aim at increasing productivity in intervention stands. Bearing in mind the lack of prior information, the goals of this study are to assess the growth of Pinus radiata in the Southeast of the province of Buenos Aires, Argentina, and to promote the implementation of early intense pruning and thinning, assessing tree behavior...

We analyze the short term effect of the harvest residues management on the Phosphorus (P) fractions of the soil. Four trials were installed in Northeast Argentina on Vertisols (S1), Mollisols (S2) and Entisols (S3 and S4). In S1 and S2 harvest residues and forest fl oor were either (1) removed (R), (2) retained (RR), 3) burnt (BR), or (4) retained...

The radiation use efficiency (RUE) model is one of the most used tools to generate large spatial and temporal scale net primary productivity (NPP) estimations by remote sensing. It involves two key issues to make accurate estimations of NPP: the estimation of the fraction of photosynthetically active radiation (PAR) intercepted by vegetation (fPAR)...

La información meteorológica resulta de gran utilidad en distintas disciplinas como la agronomía y la hidrología, entre otras. La observación de variables y fenómenos meteorológicos se lleva a cabo en Estaciones Meteorológicas Convencionales (EMC) asistidas por un observador capacitado. En los últimos años, el uso de Estaciones Meteorológicas Autom...

The effect of initial planting density on the growth and wood density of Eucalyptus globulus was examined in a trial established in the southeast of Buenos Aires Province, Argentina. A modified Nelder design was used to generate 9 planting densities ranging from 582 to 2.083 trees/ha. The effect of planting density on diameter at breast height, tot...

Argentina is the first popcorn exporting country worldwide. In 1997-1998 harvest season, 40,000 ha were sown with a production of 125,000 tons; 120,000 tons of this production were exported to more than 40 countries. The objectives of this study were to isolate and to identify the fungi present in this cereal and to assess the occurrence of mycotox...
Article
Citrinin production ability in a liquid medium, the macroscopic morphological characters and growth rate on agarized medium were observed on thirty-seven Penicillium citrinum Thorn isolates recovered from freshly harvested corn in the main production area in Argentina. It was shown that the percentage of strains with toxin ability production was hi...
Article
Corn (Zea mays) is the main cereal produced in and exported from Argentina. The risk of contamination by mycotoxins is related to the mycoflora associated with the corn kernels. This paper reports on the identification of internal and external mycoflora of corn kernels harvested in the main production area in Argentina in 1990. A mycological survey...
Article
a ABSTRACT No lineal logistic models were adjusted to model the Normalized Difference Vegetation Index (NDVI) of burned sites. Four regions were analyzed: Espinal, Monte, Yungas and Chaco seco, through the period 2003-2006. Two vegetation types were analyzed inside of each region, close shrublands and open shrublands. The outcomes show the differen...

RESUMEN Se ajustaron modelos no lineales logísticos, para modelar el índice de vegetación de diferencia normalizada (NDVI) de sitios quemados. Se analizaron cuatro regiones: Espinal; Monte; Yungas y Chaco seco, para el periodo 2003-2006. Dos tipos de vegetación fueron analizados, arbustal abier-to y arbustal cerrado. Los resultados muestran las dif...
