Changes in plant responses induced by an arthropod influence the colonization behavior of a subsequent herbivore por Silva, Diego B., Jiménez, Alejandro, Urbaneja, Alberto, Pérez-Hedo, Mertixell, Bento, José Maurício Simões

“…Both herbivorous arthropods up-regulated the expression of genes involving the jasmonic acid and abscisic acid pathways, increasing emissions of fatty-acid derivatives, but only B. tabaci increased the expression of genes related to the salicylic acid pathway and the total amount of phenylpropanoids released. …”

Origen de las epidemias del virus de la Sharka (Plum Pox Virus). Actividad vectorial y estrategias de control de la dispersión natural de virus no persistentes por Cambra, Mariano, Vidal, Eduardo, Moreno, Aránzazu, Capote, Nieves, Martínez, M. Carmen, Gorris, María T., Bertolini, Edson, Marroquin, Carlos, Cambra, Miguel A., Olmos, Antonio

“…Así, cuando un pulgón virulífero aterriza en una planta y prueba (introduce el estilete), aunque no se alimente, realiza el proceso de egestión (salivación)-ingestión de fluidos y tiene una alta probabilidad de inocular con éxito el agente patógeno en una célula sana, puesto que no se requiere ningún periodo de latencia ya que el virus está en el estilete.…”

Remote Sensing Dynamics for Analyzing Nitrogen Impact on Rice Yield in Limited Environments por Fita, David, San Bautista, Alberto, Castiñeira-Ibañez, Sergio, Franch, Belén, Domingo, Concha, Rubio, Constanza

“…There is no positive linear correlation betweenNconcentration and yield in rice cultivation because an excess ofNcan unbalance the distribution of photo-assimilates in the plant and consequently produce a lower yield. …”

NITIRSOIL: A model that balances complexity with prediction uncertainty for improving nitrogen fertilization in agriculture por De-Paz, José M., Ramos, Carlos, Visconti, Fernando, de-paz

“…Mismanagement of the nitrogen (N) fertilization in agriculture leads to low N use efficiency (NUE) and therefore pollution of waters and atmosphere due to NO3􀀀 leaching, and N2O and NH3 emissions. The use of N simulation models of the soil-plant system can help improve the N fertilizer management increasing NUE and decreasing N pollution issues. …”

Aireación en un suelo de café por Garay Irala, A.F.

“…Carbon-dioxide diffusion rate was measured by a simple absorption method employing standard sodium hydroxide solution, contained in a plastic dish, exposed under an inverted basin pressed into the soil for a fixed period. In addition to surface carbon-dioxide diffusion rate, carbon-dioxide diffusion rates at 6, 18 and 36 inches depth were also determined. …”

Analysis of the distribution of plant nutrients in a biogas production system por Johansson, André

“…Biogas pro-duction is of interest since it has the potential to reduce the use of fossil fuels and potentially also greenhouse gas emission. The use of digestate as fertilizer has the potential for a more even distribution of plant nutrients across the landscape. …”
