Seed germination of common and endangered arable weed species is differently affected by the herbicide metazachlor and its transformation products por Garcia, Andrés, Eichberg, Carsten, Wendell, Anne-Kathrin, Pfeifer, Simon, Ludewig, Kristin, Donath, Tobias W., Ulrich, Uta

“…MZ and MZ-OA increased the synchronicity of endangered species, while both TPs decreased mean germination time of endangered species. Common species showed less significant differences when compared to the control and also had a less synchronised and longer germination time compared to endangered species. …”

Modelling respiration rate of soybean seeds (Glycine max (L.)) in hermetic storage por Ochandio, Dario Carlos, Bartosik, Ricardo Enrique, Gastón, Analía Graciela Lucia, Arias Barreto, Alien, Yommi, Alejandra Karina, Abalone, Rita Mónica

“…Two correlations were used for smoothing gas concentration in time: linear and exponential. Then, the respiration rate at each temperature and m.c. combination was calculated as storage time progressed and oxygen was consumed and two predictive models for respiration were proposed: Model I (temperature and m.c. dependent) and Model II (temperature, m.c. and oxygen dependent). …”

Optimizing a fixed-precision sequential sampling plan for adult Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae), new pest on sugarcane por Perez, Maria Lucia del Pilar, Isas, Marcos Gerardo, Salvatore, Analia Ruth, Gastaminza, Gerardo, Trumper, Eduardo Victor

“…The monitoring for its occurrence and the population density usually is made by visual inspection and consequently demands much effort and time. The objectives of this study were 1) to describe the sampling distribution pattern of A. atropunctellus adults 2) to develop and validate a fixed-precision sequential sampling plan for density estimation, and 3) to find the optimum inspection time for each sampling unit. …”

Spatial distribution of volcanic ash deposits of 2011 Puyehue-Cordón Caulle eruption in Patagonia as measured by a perturbation in NDVI temporal dynamics por Easdale, Marcos Horacio, Bruzzone, Octavio Augusto

“…The aim of this study was to analyze the spatial distribution of volcanic ash deposits from the eruption of Puyehue- Cordón Caulle in 2011, by identifying a sudden change in the Normalized Difference Vegetation Index (NDVI) temporal dynamics, defined as a perturbation located in the time series.We applied a sparse-wavelet transform using the Basis Pursuit algorithm to NDVI time series obtained from the Moderate Resolution Image Spectroradiometer (MODIS) sensor, to identify perturbations at a pixel level. …”

Replacement of CTV-susceptible sour orange rootstock by CTV-tolerant ones may have triggered outbreaks of Tetranychus urticae in Spanish citrus por Bruessow, F., Asins, María J., Jaques, Josep A., Urbaneja, Alberto

“…Some parameters (sex ratio, egg hatching and survival) were not affected by the rootstock, whereas many other important ones were (fecundity, oviposition rate, lifespan and development time). These differences may explain the diversity found in the selected life history parameters (net fecundity, generation time and intrinsic rate of increase, rm). …”
