Datos sobre la variabilidad de algunos parámetros ecológicos en cuatro comunidades nitrófilas barcelonesas
(Universitat de Barcelona, Departament de Biologia Vegetal, 1988)Se estudian cuatro comunidades ruderales de 10s alrededores de Barcelona (Chenopodietum muralis, Silybo-Urticetum, Carduo-Hordeetum e Inulo-Oryzopsietum) desde una perspectiva fitosociológica (inventariosflorísticos, ... -
Degradation of agricultural biodegradable plastics in the soil under laboratory conditions
(CSIRO Publishing, 2016)Mulches, usually consisting of polyethylene films, are used in agriculture to improve production. The main drawback of using polyethylene is its extremely high stability. Removing it from the field is usually not feasible, ... -
La depredación de semillas de malas hierbas, una función ecológica a conservar y potenciar
(Asociación Española de Ecología Terrestre (AEET), 2013)La depredación de semillas de malas hierbas es un claro ejemplo de cómo la conservación de la biodiversidad de los sistemas agrarios redunda en un beneficio, tanto para el agricultor como para la sostenibilidad del sistema. ... -
Describing Polygonum aviculare emergence in different tillage systems
(European Weed Research Society, 2015)Effects of four tillage systems (direct drill, subsoiler, chisel plough and mouldboard plough) on the dynamics of Polygonum aviculare populations were studied over three growing seasons. Cumulative emergence on a weekly ... -
La determinación de nitratos en la base del tallo en el cultivo del maíz como herramienta de diagnóstico
(Mapama, 2015)La práctica de la fertilización, que supone un coste relevante en la producción del maíz, continúa sin estar resulta a escala de parcela. En este artículo nos centraremos en la fertilización nitrogenada, ya que la fertilización ... -
Dinàmica estacional de l'herba als prats montans de Sant Jaume de Frontanyà (Pirineus Orientals)
(Universitat de Barcelona, 1992)Vegetation dynamics in montane grasslands at Sant Jaume de Frontanya (Eastern Pyrenees). The study of the anual biomass variation of grasslands from Sant Jaume de Frontanya (Alt Bergueda, Barcelona), besides the analysis ... -
Distribution, morphology and habitats of saline wetlands: a case study from Monegros, Spain
(Universidad de Barcelona, 2013)Wetlands in semiarid regions have received less attention than wetlands in humidtemperate areas, and the limited amount of information has resulted in little regulatory recognition. A comprehensive map of the saline wetlands ... -
Diversity-ecosystem function relationship in mixed forage crops
(European Grassland Federation, 2010)Monocultures and three species mixtures containing a grass (Festuca arundinacea), a legume (Medicago sativa) and a forb (Cichorium intybus) were sown in order to test the effects of diversity on forage swards. Yield, LAI ... -
Diversity–interaction modeling: estimating contributions of species identities and interactions to ecosystem function
(Ecological Society of America, 2009)We develop a modeling framework that estimates the effects of species identity and diversity on ecosystem function and permits prediction of the diversity–function relationship across different types of community ... -
Early stage fruit analysis to detect a high risk of bitter pit in ‘Golden Smoothee’
(Elsevier, 2017)Fruit mineral analysis at harvest is recommended as a predictive method to assess the risk of bitter pit (BP) in apple orchards, although it only provides valuable information if conducted just before harvest. To gain more ... -
Ecosystem function enhanced by combining four functional types of plant species in intensively managed grassland mixtures: a 3-year continental-scale field experiment
(Wiley online library, 2013)A coordinated continental-scale field experiment across 31 sites was used to compare the biomass yield of monocultures and four species mixtures associated with intensively managed agricultural grassland systems. To increase ... -
Efecto de la fecha de siembra en las malas hierbas en cereales de invierno
(Interempresas, 2019-10-07)Se debe tener en cuenta que las malas hierbas son propias de cada parcela y por tanto, se debe de plantear una estrategia de control a medio y largo plazo. Esto implica no solo el cultivo, sino también el manejo del suelo ... -
Effect of patch size on seed removal by harvester ants
(European Weed Research Society, 2016-02)The harvester ant Messor barbarus can be responsible for high weed seed losses in dryland cereals in Spain. Because weeds occur in patches, harvester ants have to be able to find and exploit patches. However, seed patches ... -
