Atmospheric nitrogen deposition is one of the main threats for biodiversity and ecosystem functioning. Measurement techniques like ion-exchange resin collectors (IECs), which are less expensive and timeconsuming than conventional methods, are gaining relevance in the study of atmospheric deposition and are recommended to expand monitoring networks.

The Critical levels of atmospheric ammonia in a Mediterranean holm-oak forest in North-Eastern Spain / Aguillaume Rodríguez-O'connor, Laura (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Àvila i Castells, Anna (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Pinho, Pedro (Universidade de Lisboa. Centro de Ecologia, Evolução and Environmental Changes) ; Matos, Paula (Universidade de Lisboa. Centro de Ecologia, Evolução and Environmental Changes) ; Llop, Esteve (Universitat de Barcelona. Departament de Biologia Evolutiva, Ecologia i Ciències Ambientals) ; Branquinho, Cristina (Universidade de Lisboa. Centro de Ecologia, Evolução and Environmental Changes)
Despite recent regulations, atmospheric ammonia (NH₃) emissions have not changed much over the last decades and excessive nitrogen remains as one of the major drivers for biodiversity changes. To prevent deleterious effects on species and ecosystems, it is very important to establish safety thresholds, such as those defined by the Critical Level (CLE) concept, "the concentration above which direct adverse effects on receptors may occur, based on present knowledge.

Dry deposition and canopy uptake in Mediterranean holm-oak forests estimated with a canopy budget model : a focus on N estimations / Aguillaume Rodríguez-O'connor, Laura (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Izquieta-Rojano, Sheila (Universidad de Navarra. Laboratorio Integrado de Calidad Ambiental) ; García-Gómez, Héctor (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (Espanya)) ; Elustondo, David (Universidad de Navarra.

Bulk/wet and throughfall fluxes of major compounds were measured from June 2011 to June 2013 at four Mediterranean holm-oak (Quercus ilex) forests in the Iberian Peninsula. Regression analysis between net throughfall fluxes and precipitation indicated that the best defined canopy process was leaching for K⁺ and uptake for NH₄⁺ at all sites. [...]
