Comparison of culturing and metabarcoding methods to describe the fungal endophytic assemblage of brachypodium rupestre growing in a range of anthropized disturbance regimes
Fungal endophytes develop inside plants without visible external signs, and they may confer adaptive advantages to their hosts. Culturing methods have been traditionally used to recognize the fungal endophytic assemblage, ... -
Decoupling of traditional burnings and grazing regimes alters plant diversity and dominant species competition in high-mountain grasslands
Over millennia, the combination of controlled burnings and extensive grazing has maintained mosaic landscapes and preserved mountain grasslands in southern Europe. In the last century, deep socio-economic changes have led ... -
Disruption of traditional grazing and fire regimes shape the fungal endophyte assemblages of the tall-grass Brachypodium rupestre
The plant microbiome is likely to play a key role in the resilience of communities to the global climate change. This research analyses the culturable fungal mycobiota of Brachypodium rupestre across a sharp gradient of ... -
Efectos de una quema prescrita sobre el suelo y la vegetación de un pasto altimontano del Pirineo navarro
(Sociedad Española para el Estudio de los Pastos, 2012) Contribución a congreso / Biltzarrerako ekarpenaLas quemas prescritas son una herramienta que tradicionalmente se ha utilizado en el Pirineo occidental para controlar la biomasa herbácea y arbustiva y mejorar la calidad de los pastos. Sin embargo, las consecuencias de ... -
¿Están los bosques mixtos pirenaicos de pino silvestre y haya en el camino hacia la saturación por nitrógeno?
Las actividades humanas causan altos niveles de deposición atmosférica crónica de N que pueden estar trastornando el ciclo del N en los bosques de los Pirineos occidentales. Para probar esta hipótesis, se han investigado ... -
Formando futuras investigadoras: introduciendo la ciencia ecológica y ambiental al mundo escolar
A pesar de su relevancia social creciente, la ciencia ecológica y ambiental está pasando por momentos muy bajos en los programas educativos de secundaria y bachillerato en nuestro país. En muchos centros escolares, la ... -
Interactions between biogeochemical and management factors explain soil organic carbon in Pyrenean grasslands
Grasslands are one of the major sinks of terrestrial soil organic carbon (SOC). Understanding how environmental and management factors drive SOC is challenging because they are scale-dependent, with large-scale drivers ... -
Land use change effects on carbon and nitrogen stocks in the Pyrenees during the last 150 years: a modelling approach
In the southern Pyrenees, human population and therefore land uses have changed from forests to pastures, then crops, and back to pastures and secondary forests during the last two centuries. To understand what such rapid ... -
Non-systemic fungal endophytes in Carex brevicollis may influence the toxicity of the sedge to livestock
(Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2014) Artículo / ArtikuluaThe sedge Carex brevicollis is a common component of semi-natural grasslands and forests in temperate mountains of Central and Southern Europe. The consumption of this species causes a severe toxicity to livestock, ... -
Nuevos retos de la ganadería extensiva: un agente de conservación en peligro de extinción = Abeltzaintza estentsiboaren erronka berriak: galtzeko arriskuan dagoen kontserbazio eragilea. 51 Reunión Científica de la SEEP
(Sociedad Española para el Estudio de los Pastos, 2012) Contribución a congreso / Biltzarrerako ekarpenaLos pastos alimentan a nuestras cabañas ganaderas de forma segura, sana y trazable, siendo el alimento más económico y el más adecuado para el sustento del ganado. Los animales herbívoros han coevolucionado a lo largo de ... -
Plant diversity patterns and soil nitrogen dynamics after controlled burnings applied to restore mountain grasslands and create resilient landscapes
Esta tesis engloba tres trabajos científicos que se centran en los efectos del desacoplamiento de los regímenes de las perturbaciones fuego y pastoreo en los suelos y en la dinámica de la vegetación. En resumen, los ... -
Plant functional diversity, climate and grazer type regulate soil activity in natural grasslands
Global change modifies vegetation composition in grasslands with shifts in plant functional types (PFT). Although changes in plant community composition imply changes in soil function, this relationship is not well understood. ... -
Pyric herbivory increases soil microbial diversity but has a site-dependent effect on soil mesofauna in the mid-term
Woody plant encroachment threatens grassland biomes at a global scale. Pyric herbivory combines prescribed burnings and targeted grazing to restore open habitats and has proved to be successful in promoting landscape and ... -
Relating the spatial distribution of a tall-grass to fertility islands in a temperate mountain grassland
Plant-soil feedback mechanisms influence the abundance and rarity of plant species and can favour invasive processes, including those of native species. To explore these mechanisms, we analysed correlations between spatial ... -
Soil bacterial functional diversity mirrors the loss of plant diversity by the expansion of a native tall-grass in high mountain grasslands
Background and Aims: In highland ecosystems, global change processes are intense and foster vegetation shifts that may have an impact on soil functioning. Soil bacterial communities may be particularly sensitive to these ... -
Soil C/N ratios cause opposing effects in forests compared to grasslands on decomposition rates and stabilization factors in southern European ecosystems
Soils store an important amount of carbon (C), mostly in the form of organic matter in different decomposing stages. Hence, understanding the factors that rule the rates at which decomposed organic matter is incorporated ... -
A survey of culturable fungal endophytes from festuca rubra subsp. pruinosa, a grass from Marine Cliffs, reveals a core microbiome
Festuca rubra subsp. pruinosa is a perennial grass that inhabits sea cliffs of the Atlantic coasts of Europe. In this unhospitable environment plants grow in rock crevices and are exposed to abiotic stress factors such as ...
