Title A name given to the resource Artificial Neural Network to Predict Vine Water Status Spatial Variability Using Multispectral Information Obtained from an Unmanned Aerial Vehicle (UAV) Creator An entity primarily responsible for making the resource Tomas Poblete, Samuel Ortega-Farías, Miguel Angel Moreno, Matthew Bardeen Description An account of the resource Water stress, which affects yield and wine quality, is often evaluated using the midday stem water potential (Ψstem). However, this measurement is acquired on a per plant basis and does not account for the assessment of vine water status spatial variability. The use of multispectral cameras mounted on unmanned aerial vehicle (UAV) is capable to capture the variability of vine water stress in a whole field scenario. It has been reported that conventional multispectral indices (CMI) that use information between 500–800 nm, do not accurately predict plant water status since they are not sensitive to water content. The objective of this study was to develop artificial neural network (ANN) models derived from multispectral images to predict the Ψstem spatial variability of a drip-irrigated Carménère vineyard in Talca, Maule Region, Chile. The coefficient of determination (R2) obtained between ANN outputs and ground-truth measurements of Ψstem were between 0.56–0.87, with the best performance observed for the model that included the bands 550, 570, 670, 700 and 800 nm. Validation analysis indicated that the ANN model could estimate Ψstem with a mean absolute error (MAE) of 0.1 MPa, root mean square error (RMSE) of 0.12 MPa, and relative error (RE) of −9.1%. For the validation of the CMI, the MAE, RMSE and RE values were between 0.26–0.27 MPa, 0.32–0.34 MPa and −24.2–25.6%, respectively.

Title A name given to the resource Ocorrência e ecologia trófica de quatro espécies de Astyanax (Characidae) em diferentes rios da bacia do rio Tibagi, Paraná, Brasil Occurrence and trophic ecology of four species of Astyanax (Characidae) in different rivers of the Tibagi River Basin, Paraná, Brazil Creator An entity primarily responsible for making the resource Sirlei Terezinha Bennemann, Ana Maria Gealh, Mário Luís Orsi, Leda Maria de Souza Description An account of the resource Na bacia do rio Tibagi, trechos dos rios Fortaleza, Iapó e Tibagi foram amostrados mensalmente, de maio de 2001 a abril de 2002, com tarrafas e redes de espera de diferentes malhagens. Foram capturados indivíduos de quatro espécies de Astyanax. Para conhecer como essas espécies utilizam o hábitat desses rios, foi calculada a constância, e as freqüências em número de exemplares foram comparadas pela análise de similaridade Bray-Curtis. A composição percentual dos alimentos consumidos foi ordenada usando-se a Análise de Componentes Principais (ACP). As proporções dos recursos alimentares foram avaliadas e classificadas quanto à natureza (animal ou material vegetal) e origem (alóctone e autóctone). A constância e a baixa similaridade na abundância revelaram que as espécies têm preferências quanto ao porte do rio ou por determinado hábitat. Astyanax altiparanae Garutti & Britski, 2000 e A. fasciatus (Cuvier, 1819) ocorreram nos de maior porte, mas foram constantes somente no rio Tibagi. Astyanax eigenmanniorum (Cope, 1894) ocorreu em todos os rios, mas prefere hábitats próximos às desembocaduras de afluentes de grandes rios. Astyanax scabripinnis (Jenyns, 1842) esteve restrita ao Fortaleza, o rio de menor porte, subafluente do rio Tibagi. O número de itens alimentares consumidos variou de 11 a 23. Entre os alimentos principais, três itens foram comuns para as quatro espécies: restos de plantas (folhas e sementes de plantas terrestres), restos de insetos (de diferentes origens e não identificados) e plantas aquáticas. Os vegetais e os insetos foram os principais alimentos para todas as espécies. A maior distinção na composição da dieta foi constatada para A. eigenmaniorum, devido à sua habilidade em explorar as plantas aquáticas, presentes em abundância, consumidas junto com carvão/sedimento, que estavam nas margens rochosas do rio Iapó. A similaridade quanto à origem e ao tipo de alimento consumido pelas quatro espécies e as diferenças em termos de hábitat ocupado podem explicar por que apenas uma delas se mantém em abundância e constância em cada trecho estudado.Stretches of the Rivers Fortaleza, Iapó and Tibagi were monthly sampled with gillnets of different mesh sizes and castnets from May 2001 to April 2002 in the Tibagi River basin. Specimens of four species of the Astyanax genera were captured. In order to assess how they use habitat and food resources in the different rivers, their constancy was calculated and the number of specimens was compared by using the Bray-Curtis similarity analysis. The composition (percentage) of food items consumed was ordered by using the Principal Components Analysis (PCA). The proportion of different food items in the diet was assessed and classified according to type (animal or plant material) and origin (allochtonous or autochtonous). The low similarity and constancy showed differences in the type of habitat preferred by the four fish species. Astyanax altiparanae Garutti & Britski, 2000 and A. fasciatus (Cuvier, 1819) were present in the large rivers but were constant only in the Tibagi River. Astyanax eigenmanniorum (Cope, 1894) was present in all rivers but prefers habitats in the mouth of affluents of large rivers. Astyanax scabripinnis (Jenyns, 1842) was restricted to Fortaleza River, a small Tibagi River affluent. The number of food items consumed by the different species varied from 11 to 23. Among the main food, three items were common for the four species: 1- plant residuals (leaves and seeds from the earth community of plants), 2- insect residuals (from different origins and unidentified) and 3- aquatic vegetation. So plants and insects were the main food consumed by all the species. Astyanax eigenmanniorum showed the highest distinction in the diet composition among the species studied. Such distinction was due to its ability of exploring an abundant food resource: the aquatic plants that were consumed together with portions of coal/sediments near the rocky shores at the Iapó River. The similarity of the origin and type of food consumed by the four species and the differences in terms of the habitat occupied may explain why one species is abundant and constant in only one of the river stretches studied.

Title A name given to the resource Histología y morfometría del ojo del pez dulceacuícola Paracheirodon axelrodi (Characiformes: Characidae) Creator An entity primarily responsible for making the resource Mario O Tovar, Martha J Obando, Edwin Gómez, María L Caldas, Hernán Hurtado Description An account of the resource El pez dulceacuícola P. axelrodi es de gran importancia comercial en la Orinoquía Colombiana y a nivel mundial, pero carece de estudios acerca de su visión. Se utilizaron diez individuos, con longitud total promedio de 2.7 cm (SD= 0.2, n= 20). Se realizaron cortes a 8 μm y se tiρeron con H-E. El tamaρo relativo del ojo es 9.8% (SD= 1.1, n= 20); el cristalino tiene un tamaρo relativo de 64.3% (SD= 4.9, n=20). Una esclerótica con tejido cartilaginoso. La retina está constituida por ocho capas y dos membranas, hay areae centrales en la zona posterior, por lo tanto tiene mayor espesor que la zona lateral. El espesor promedio de las estructuras es: retina lateral: 144.5 μm (SD= 5.4, n= 20), retina temporal: 210.4 μm (SD= 14.8, n= 20); cristalino (esfιrico): dorso-ventral 759.6 μm (SD= 31.7, n= 20) y antero- posterior 763.4 μm (SD= 30.7, n= 20) y cσrnea: 27.6 μm (SD= 4.3, n= 20). El tamaρo relativo del ojo, relacionado con la presencia de areae centrales y una córnea delgada, muestra las necesidades visuales del neón cardenal (cazador) para adaptarse al hábitat, lo que hace necesario tener un sistema visual desarrollado que le permita tener mejor sensibilidad y resolución visual.Histology and morphometry of the eye in the freshwater Paracheirodon axelrodi (Characiformes: Characidae). The visual system of Teleost fishes has a wide range of adaptations. The eye has suffered modifications, mainly towards better sensitivity and visual resolution according to specific environmental conditions. In that way, this organ is so important for survival. In spite of being the most commercialized Orinoquía species, and one of the most important ornamental fish worldwide, there are almost no studies on the communication systems of P. axelrodi (including vision). We studied the eye in ten individuals of P. axelrodi, with a mean total length of 2.7 cm (SD= 0.2, n= 20). We measured eye relative size (TRO) after sacrifice. Heads were processed for hematoxylin-eosin, and 8 μm thick sections were obtained. Images were digitalized for histological identification and morphometrics. The relation between TRO and body length was 9.8% (SD= 1.1, n= 20); lens was spherical with a relative size of 64.3% (SD= 4.9, n= 20). Rete mirabilis choroid was composed mainly by capillaries, while sclera was composed of cartilaginous tissue. Retina with eight layers and two membranes. An areae centrales was observed in the posterior retina. Iris covered by a simple cubic epithelium. Cornea of endothelial tissue with two membranes. Pupil almost circular, with a naso-caudal elongation. Measures of retina thickness were as follows: lateral retina 144.5 μm (SD= 5.4, n= 20), temporal retina 210.4 μm (SD= 14.8, n= 20). Lens measurements were: dorso- ventral 759.6 μm (SD= 31.7, n= 20), antero-posterior 763.4 μm (SD= 30.7, n= 20). Cornea thickness was 27.6 μm (SD= 4.3, n= 20); iris thickness was 18.9 μm (SD= 1.9, n= 20); rete mirabilis choroid 22.2 μm (SD= 3.2, n= 20) and sclera: 15.9 μm (SD= 1.2, n= 20). This species has a typical Teleost eye conformation. The retina was thicker in the posterior area, probably related to the presence of neuron groups. This modification allows for a better sharpness and visual resolution. The TRO, areae centrales in the retina, and thin cornea, suggests the need of a well developed visual system resulting from a predatory diet. Rev. Biol. Trop. 57 (4): 1107-1118.

Title A name given to the resource Cambios en la composición bioquímica y su aplicabilidad en el uso de follajes verdes como fuente de materia orgánica y nutrimentos en sistemas agroforestales Biochemical Changes and their Application for Green Manure use, as Organic Matter and Nutrient Source, in Agroforestry Systems Creator An entity primarily responsible for making the resource Argüello Arias Heliodoro Description An account of the resource El uso de abonos verdes es una práctica que, potencialmente, puede ofrecer además de beneficios indirectos como conservación de suelos, así como su humedad e incremento de los microorganismos presentes en él, otros beneficios directos como el aporte de materia orgánica y nutrimentos al suelo. Sin embargo, los agricultores muchas veces omiten esta práctica por la aparente escasez de fuentes de abono verde en sus fincas, ignorando que algunas especies arbóreas, presentes en sus fincas o en las de sus vecinos, pueden constituirse en las fuentes buscadas. En otro caso, si el agricultor está usando abonos verdes, la mayoría de las veces, ignora si el material usado es capaz de descomponerse y liberar los nutrimentos en el lapso que corresponde al desarrollo del cultivo. En este sentido, lo ideal sería conocer tanto la curva de nutrientes requeridos por el cultivo, como la curva de liberación de los mismos a través del tiempo, a fin de ajustar las dos en el campo para lograr la máxima eficiencia. En las dos situaciones planteadas, es importante disponer de un indicador que permita elegir una fuente de abono verde en el momento de su aplicación. Hasta ahora, esto se puede lograr a través de estudios exhaustivos de la dinámica de descomposición. Sin embargo, estos estudios son complejos y costosos en dinero y tiempo, por lo tanto inaccesibles para el agricultor. En este trabajo se evalúan los indicadores más importantes, reportados por la literatura, a través del proceso de descomposición y liberación de nutrimentos del follaje de ocho especies de interés agroforestal en la franja premontano de Colombia y se concluye que, para este grupo de especies, la relación ligninalnitrógeno inicial del follaje resultó ser el indicador más robusto, permitiendo predecir la velocidad de descomposición.Using green manure potentially can offer indirect benefits, like soil soil conservation and improvement of soil humidity and soil microorganisms; as well as direct benelits like organic matter and nutrients. However, some farmers do not adopt this technology due the apparent scarcity of the green manure sources in their farms, ignoring the fact that some species, present in their farms or close to them, can fill their requirements. In other situation, when the farmer already is using green manure, in most cases, he ignores if the used material is able to release the organic matter and nutrients, matching the crop requirements, during the season growth. In this way, the goal could be that the farmer be able to apply both, the curve of the crop nutrient requirements, and the curve of the green manure nutrient release, to achieve the best crop performance. In both of the described situations it is important to have an indicator to choose a green manure source. Today it is possible to know the decomposition and mineralization rates and dynamies, through expensive, in time and money, besides of very complex experiments. In consecuence practicaliy no farmers are interested in doing them. This research tested the most important decomposition indicators, reported by the literature, through the decomposition and nutrient release process observed in the foliage of eight common species from the Colombian Midlands. The foundings of this research suggest that for the tested species the lignine/nitrogen ratio is the most robust indicator predicting the decomposition rate.

Title A name given to the resource Determinantes de la transmisión de dengue en Veracruz: un abordaje ecológico para su control Creator An entity primarily responsible for making the resource Escobar-Mesa Javier, Gómez-Dantés Héctor Description An account of the resource OBJETIVO: Identificar los factores ambientales, sociales y demográficos que contribuyen a explicar las diferencias en la transmisión de dengue en Veracruz, México, durante el periodo 1995-1998 y definir las áreas de riesgo para promover un mejor control del problema. MATERIAL Y MÉTODOS: Bajo un diseño ecológico se analizó una base de datos con el número de casos de dengue que se presentaron en 1 249 localidades en las 11 Jurisdicciones Sanitarias del estado de Veracruz durante el periodo 1995-1998. Cada una de las localidades fue identificada de acuerdo con su altitud, latitud y longitud, y con el número total de la población por sexo, el número de viviendas y la dotación de servicios públicos. Se tomó también el índice de marginación por localidad del Consejo Nacional de Población. RESULTADOS: El dengue en Veracruz se registró en 17% de las localidades y en sólo 6% de ellas se concentraron 70% de los casos de dengue en el estado. Las localidades repetidoras de dengue fueron grandes centros urbanos, con baja marginación y extensa dotación de servicios públicos. El dengue sí se transmite en las áreas rurales del estado aunque la transmisión es ocasional. El promedio de casos de dengue reportados en las localidades dependió del tamaño de la misma y del número de años que reportaron dengue durante el periodo. Se reporta un umbral poblacional para la transmisión. CONCLUSIONES: Se identificaron las localidades repetidoras de dengue que concentran 70% de los casos, y las determinantes sociales y ambientales de la transmisión. Este enfoque de riesgo puede mejorar el control y tener un impacto significativo en la prevención de la transmisión en las zonas de mayor riesgo.
