Relationship between physical fitness, body composition indicators and physical activity components in Spanish schoolchildren
Esta Tesis Doctoral se basa en un proyecto de investigación longitudinal del grupo E-FIT (Ejercicio físico, salud y calidad de vida) denominado 'Observatorio de Actividad Física en población escolar https://observatorio ... -
Tree-to-tree competition in mixed European beech-Scots pine forests has different impacts on growth and water-use efficiency depending on site condition.
Mixed conifer-hardwood forests can be more productive than pure forests and they are increasingly considered as ecosystems that could provide adaptation strategies in the face of global ... -
Temporal interactions among throughfall, type of canopy and thinning drive radial growth in an Iberian mixed pine-beech forest
Many factors can influence tree growth over time such as different forest management practices, climate or tree-to-tree interactions, especially in mixed forests. We show in this work how the temporal growth patterns ... -
Forest landscape hydrology in a "new normal" era of climate and land use change
This chapter aims to clarify the effects that changing climate and quantity, quality and pattern of tree cover in forests have on the way water becomes available for human use and ecosystem integrity. To do this, the ... -
Climate-forest-water-people relations: seven system delineations
In this chapter, we review current scientific understanding and hypotheses at seven system delineations that build up from the level of a ‘tree’ interacting with water, to that of a social-ecological system at the scale ... -
Determinants of the forest-water relationship
Our analysis of forest-water relations addresses four important subsystems of a linked planetary social-ecological system: climate, forests, water and people. In this chapter, we consider how each of these subsystems ... -
Physiological and biochemical characterization of rootlets response to salt stress in two Medicago truncatula Gaertn. ecotypes
Legumes are very important plants both ecologically and agriculturally because they are able to interact symbiotically with rhizobia for biological nitrogen fixation and soil fertilization. Medicago truncatula Gaertn. is ... -
Evaluación del efecto de los inhibidores de la nitrificación derivados de dimetilpirazol y la nutrición amoniacal sobre la fisiología de las plantas
Los inhibidores de la nitrificación (IN) pueden ser bien productos biológicos producidos por las plantas o de síntesis química, estos últimos son añadidos a los fertilizantes granulados, solubles o líquidos y del mismo ... -
Physiological action of herbicides inhibiting amino acid biosynthesis and their sustainable mixtures in Amaranthus palmeri sensitive and resistant to glyphosate
Durante el siglo pasado, la producción agrícola se ha ido incrementando en todo el mundo gracias a la mejora en sus técnicas de manejo. Una de las herramientas más poderosas para alcanzar ese incremento en la producción ... -
Multi-scale approach to forest functioning of Pinus sylvestris L. and Fagus sylvatica L. mixtures of the Pyrenees under global change
Hoy en día, los bosques mixtos son cada vez más reconocidos como superiores a los bosques puros en cuanto a la provisión de una completa gama de bienes y servicios ecosistémicos. La gestión de los bosques en una condición ... -
Bringing the natives back: identifying and alleviating establishment limitations of native hardwood species in a conifer plantation
To facilitate the reintroduction of five native late-successional Taiwanese Fagaceae species into Japanese cedar (Cryptomeria japonica (D.) Don) plantations, we experimented with methods to alleviate their establishment ... -
Drought-induced changes in wood density are not prevented by thinning in Scots pine stands
Density is an important wood mechanical property and an indicator of xylem architecture and hydraulic conductivity. It can be influenced by forest management and climate. We studied the impact of thinning and climate ... -
Modelling the management of forest ecosystems: importance of wood decomposition
Scarce and uncertain data on woody debris decomposition rates are available for calibrating forest ecosystem models, owing to the difficulty of their empirical estimations. Using field data from three experimental sites which ... -
Sustainable management of metasequoia glyptostroboides plantation forests in Shanghai
Urban forestry is increasingly used as a tool for climate change mitigation and for providing environmental services to inhabitants of urban areas. However, tree species used in urban forestry are usually different from ... -
Complementary evaluation of iron deficiency root responses to assess the effectiveness of different iron foliar applications for chlorosis remediation
Iron deficiency in plants is caused by a low availability of iron in the soil, and its main visual symptom is leaf yellowing due to a decrease in chlorophyll content, along with a reduction in plant growth and fruit quality. ... -
Integration of a communal henhouse and community composter to increase motivation in recycling programs: overview of a three-year pilot experience in Noáin (Spain)
This paper presents a three-year pilot experience of a new municipal waste management system developed in Navarre, Spain that integrates composting and hens. The aim of this new system is to motivate the general public to ... -
Tillage effects on soil quality after three years of irrigation in Northern Spain
Irrigation is being initiated on large areas of traditionally rainfed land to meet increasing global demand for food, feed, fiber and fuel. However, the consequences of this transition on soil quality (SQ) have scarcely ... -
The pattern of shikimate pathway and phenylpropanoids after inhibition by glyphosate or quinate feeding in pea roots
The shikimate pathway is a metabolic route for the biosynthesis of aromatic amino acids (AAAs) (i.e. phenylalanine, tyrosine, and tryptophan). A key enzyme of shikimate pathway (5-enolpyruvylshikimate-3-phosphate synthase, ... -
Overexpression of a pine Dof transcription factor in hybrid poplars: A comparative study in trees growing under controlled and natural conditions
In this work, the role of the pine transcriptional regulator Dof 5 in carbon and nitrogen metabolism has been examined in poplar trees. The overexpression of the gene and potential effects on growth and biomass production ... -
Compostaje descentralizado de residuos orgánicos domiciliarios a pequeña escala: estudio del proceso y del producto obtenido
Las más recientes políticas europeas en materia de residuos contemplan un sistema jerárquico de opciones de gestión, en el cual las acciones de prevención constituyen la más alta prioridad. Desde los años noventa el ...
