DendroSync: An R package to unravel synchrony patterns in tree-ring networks
(Elsevier, 2017-12-15)Spatial synchrony refers to the presence of a common signal for a time-varying characteristic that, in dendrosciences, is shared among tree-ring chronologies from a particular area. Analysis and interpretation of synchrony ... -
Densidad poblacional de pulgones en cultivares de alfalfa en los regadios de Lleida
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (Espanya), 1999)De 1995 a 1997 se evaluó, en pequeñas parcelas de campo, la densidad de pulgones en siete cultivares de alfalfa, de orígenes español, francés y estadounidense. Las especies de pulgones infestantes fueron Aphis craccivora, ... -
Desarrollo larvario y número de estadios larvarios de Pseudaletia unipuncta alimentada con dos variedades de maíz y dos dietas semisintéticas
(Espanya. Ministerio de Medio Ambiente y Medio Rural y Marino, 2008)Pseudaletia ( Mythimna) unipuncta (Haworth) es una plaga defoliadora del maíz presente año tras año en la Cuenca del Ebro, que realiza en el maíz daños esporádicos pero a veces devastadores. La implantación creciente de ... -

(Espanya. Ministerio de Medio Ambiente y Medio Rural y Marino, 2004)Se estudió el ciclo biológico de Dryomia lichtensteini (F. Löw) en una población de encinas de Lleida y se describieron los diferentes estados de desarrollo del díptero. Los adultos aparecieron en abril y volaron hasta ... -
Designing and evaluating arable cropping systems with cash and cover crop legumes in sole crop and intercrop to improve nitrogen use efficiency
(Juniper Publishers, 2017-11-15)This paper aimed at synthetizing: i. Impact of sole grain legume at the rotation level, ii. Potential of grain legume intercrops for improving yield and cereal protein content and iii. Potential of cover crops including ... -
Detection of Drepanaphis acerifoliae (Thomas) [Hemiptera: Aphididae: Drepanosiphinae] Sugar maple trees, Acer saccharinum, in Spain
(Sociedad Entomológica Aragonesa, 2008)The nearctic species Drepanaphis acerifoliae (Thomas) is reported for the first time in the Iberian Peninsula, on sugar maple trees (Acer saccharinum) used in landscape gardening. The species, already known in Europe ... -
Detection of Tuber melanosporum DNA in soil
(Oxford University Press, 2006)Our objectives were (i) to develop a molecular method to detect mycelia of Tuber melanosporum (black truffle) in soil and (ii) to test for mycelial distribution around two truffle-bearing Quercus ilex trees in a truffle ... -
