Eliminación de nitratos por desnitrificación en la zona no saturada del suelo en un humedal del cinturón Peri-Urbano de Vitoria-Gasteiz [PDF]
, 2003 Los cambios de usos del suelo y la intensificación de la agricultura en el acuífero cuaternario de Vitoria-Gasteiz llevaron a la desaparición de los humedales. Acciones recientes de restauración en el área peri-urbana han llevado a su recuperación.

Ecological Entomology, EarlyView.The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

New Phytologist, EarlyView.Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Beyond species means – the intraspecific contribution to global wood density variation
New Phytologist, EarlyView.Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Unveiling the multidimensional nature of policy acceptability: A cross‐national approach
Policy Studies Journal, EarlyView.Abstract Research on mass attitudes toward public policy often centers on preferences, yet the understudied facet of policy acceptability remains pivotal. This study develops and validates a nuanced measure of acceptability that identifies three dimensions: political, affective, and deliberative.

Gender Dimensions of Support for Local Policy: Resident, Policymaker, and Policy Gender
Policy Studies Journal, EarlyView.ABSTRACT There is a well‐established triadic relationship between satisfaction with public services, trust in leaders, and policy support in developed democracies. This study takes a novel approach by considering how gender is associated with the strength and direction of these connections, an element underexplored in the literature.
