Temperature sensitivity of soil respiration rates enhanced by microbial community response
(Springer Nature, 2014-09-03)Soils store about four times as much carbon as plant biomass1, and soil microbial respiration releases about 60 petagrams of carbon per year to the atmosphere as carbon dioxide2. Short-term experiments have shown that soil ... -

The Agrodiversity Experiment: three years of data from a multisite study in intensively managed grasslands
(2014-06-11)Intensively managed grasslands are globally prominent ecosystems. Weinvestigated whether experimental increases in plant diversity in intensively managedgrassland communities can increase their resource use efficiency.This ... -
The role of light in the emergence of weeds: using Camelina microcarpa as an example
(Public Library of Science, 2015)When modelling the emergence of weeds, two main factors are considered that condition this process: temperature and soil moisture. Optimum temperature is necessary for metabolic processes that generate energy for growth, ... -
The stable isotope ecology of terrestrial plant succession
(Taylor & Francis, 2011)We review the relevance and use of stable isotopes for the study of plant community succession. Stable isotope measurements provide information on the origin of resources acquired by plants, the processes governing resource ... -
Transcriptional regulation of the rice arginine decarboxylase (Adc1) and S-adenosylmethionine decarboxylase (Samdc) genes by methyl jasmonate
(Elsevier, 2010)We investigated the effect of methyl jasmonate (MeJa) treatment on the expression of two genes in the rice polyamine biosynthesis pathway and on the polyamine content in wild type plants and transgenic rice plants expressing ... -
Transdisciplinary weed research: new leverage on challenging weed problems?
(Wiley, 2016)Transdisciplinary weed research (TWR) is a promising path to more effective management of challenging weed problems. We define TWR as an integrated process of inquiry and action that addresses complex weed problems in the ... -
Tree—Open Grassland Structure and Composition Drive Greenhouse Gas Exchange in Holm Oak Meadows of the Iberian Peninsula
(MDPI, 2020-12-28)Iberian holm oak meadows are savannah-like ecosystems that result from traditional silvo-pastoral practices. However, such traditional uses are declining, driving changes in the typical tree—open grassland structure of ... -
Turnover of grassland roots in mountain ecosystems revealed by their radiocarbon signature: role of temperature and management
(Public Library of Science, 2015)Root turnover is an important carbon flux component in grassland ecosystems because it replenishes substantial parts of carbon lost from soil via heterotrophic respiration and leaching. Among the various methods to ... -
Unravelling the resistance mechanisms to 2,4-D (2,4-dichlorophenoxyacetic acid) in corn poppy (Papaver rhoeas)
(Elsevier Inc., 2016-10)In southern Europe, the intensive use of 2,4-D (2,4-dichlorophenoxyacetic acid) and tribenuron-methyl in cereal crop systems has resulted in the evolution of resistant (R) corn poppy (Papaver rhoeas L.) biotypes. Experiments ... -
Update on the risk of introduction of african swine fever by wild boar into disease-free European Union countries
(Blackwell Verlag GmbH, 2016-07-06)Despite efforts to prevent the appearance and spread of African swine fever (ASF) in the European Union, several Member States are now affected (Lithuania, Poland, Latvia and Estonia). Disease appearance in 2014 was ... -
Using fitness parameters to evaluate three oilseed Brassicaceae species as potential oil crops in two contrasting environments
(Elsevier, 2017)Thlaspi arvense and Camelina sativa have gained considerable attention as biofuel crops. But in some areas, these species, including C. microcarpa, are becoming rare arable plants because of agricultural intensification. ... -
Using the response-effect trait framework to quantify the value of fallow patches in agricultural landscapes to pollinators
(Wiley, 2018-02-10)Questions: What is the role of managed fallow habitats in providing resources for pollination services in agricultural landscapes? How is resource provision affected by fallow management and landscape structure? Can the ... -
Valoración de los recursos pastorales de la comarca de la Alta Ribagorça (pirineos centrales, Catalunya): repercusión sobre el proceso de conversión a ganadería ecológica
(Sociedad Española para el Estudio de los Pastos, 2005)La conversión de más de la mitad de las explotaciones ganaderas de la comarca de la Alta Ribagorça al sistema productivo ecológico puede verse comprometida por la falta de pastos y forrajes certificados como tales. Este ... -
