The Montseny brook newt (Calotriton arnoldi) is a critically endangered amphibian species which inhabits a small 20 km 2 holm oak and beech forest area in NE Spain. Calotriton arnoldi strictly lives in running waters and might be highly vulnerable to hydrological perturbations expected to occur under climate and vegetation cover changes. [...]

Pols africana a Tenerife i al Montseny
/
Àvila i Castells, Anna (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Investigadors del CREAF han comparat la deposició atmosfèrica de pols, per via seca i humida, en dues regions de contrastada influència africana: l'illa de Tenerife i el massís del Montseny. Les dades mostren que els elements procedents de la pols africana es dipositen majorment en forma de deposició humida al Montseny, mentre que a les Canàries predomina la deposició seca. [...]
Investigadores del CREAF han comparado la deposición atmosférica de polvo, por vía seca y húmeda, en dos regiones de contrastada influencia africana: la isla de Tenerife y el macizo del Montseny. [...]
Researchers at CREAF have compared the amounts of dust deposited through the wet and dry pathways in two regions of contrasted African influence: the Tenerife Island and the Montseny massif. Data show that elements from African dust were mostly delivered as wet deposition in Montseny, while in the Canary Islands dry deposition predominated. [...]

Determinació del nivell crític de contaminació per amoni en una zona ramadera de Catalunya
/
Àvila i Castells, Anna (Centre de Recerca Ecològica i d'Aplicacions Forestals)
El nitrogen que conté l'amoni és un nutrient essencial per a la vida, però quan la deposició depassa la capacitat de processament dels ecosistemes esdevé una amenaça ambiental. Investigadors de la UAB han determinat quin és el nivell crític de concentració d'amoni a l'aire a partir de l'efecte en els líquens, molt sensibles a la contaminació atmosfèrica.
El nitrógeno que contiene el amonio es un nutriente esencial para la vida, pero cuando la deposición rebasa la capacidad de procesamiento de los ecosistemas se convierte en una amenaza ambiental. Investigadores de la UAB han determinado cuál es el nivel crítico de concentración de amonio en el aire a partir del efecto en los líquenes, muy sensibles a la contaminación atmosférica.
The nitrogen contained in ammonia is an essential nutrient for life, but when deposition exceeds the processing capacity of ecosystems it becomes an environmental threat. Researchers at the UAB have determined the critical level for ammonia atmospheric concentration by studying its effects on lichens, which are very sensitive to air pollution.

To assess the impact of nitrogen (N) pollutants on forest ecosystems, the role of the interactions in the canopy needs to be understood. A great number of studies have addressed this issue in heavily N-polluted regions in north and central Europe. [...]

This study considers the role of distance to the African source on the amount of deposition. To this end, dry and wet deposition was measured at a site close to Africa (Santa Cruz de Tenerife in the Canary Islands, SCO) and at a distant site located in NE Spain (La Castanya, Montseny, MSY). [...]

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. [...]

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.

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.
