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 ... -
A proteomic approach reveals new actors of nodule response to drought in split-root grown pea plants
Drought is considered the more harmful abiotic stress resulting in crops yield loss. Legumes in symbiosis with rhizobia are able to fix atmospheric nitrogen. Biological nitrogen fixation (SNF) is a very sensitive process ... -
Split‐root systems applied to the study of the legume‐rhizobial symbiosis: what have we learned?
Split-root system (SRS) approaches allow the differential treatment of separate and independent root systems, while sharing a common aerial part. As such, SRS is a useful tool for the discrimination of systemic (shoot ... -
Nodule performance within a changing environmental context
Global climate models predict that future environmental conditions will see alterations in temperature, water availability and CO2 concentration ([CO2]) in the atmosphere. Climate change will reinforce the need to develop ... -
Pea plant responsiveness under elevated [CO2] is conditioned by the N source (N2 fixation versus NO3 fertilization)
The main goal of this study was to test the effect of [CO2] on C and N management in 2different plant organs (shoots, roots and nodules) and its implication in the 3responsiveness of exclusively ... -
Estudio de prospectiva, análisis y propuesta de participación y colaboración de la Administración Foral de Navarra con las redes, plataformas e iniciativas de ciencia ciudadana
El objetivo de este trabajo es analizar las redes y plataformas de ciencia ciudadana existentes con el fin de realizar una propuesta para su implementación en Navarra por parte de la Administración Ambiental; para ello se ... -
Caracterización de opus tesselatum procedentes de Ávila, España
Se han estudiado diversas muestras de Opus tesselatum procedentes de excavaciones arqueológicas de urgencia en Ávila (España) para determinar su origen y las tecnologías de producción utilizadas en su fabricación. Las ... -
Vidrios romanos de Bracara Augusta (Portugal): análisis arqueométrico
En este trabajo se han estudiado vidrios romanos de Bracara Augusta, actualmente Braga (Portugal), a través de su composición química, analizando los constituyentes mayoritarios, minoritarios y traza mediante espectrometría ... -
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 ... -
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. ... -
Elevated CO2 improved the growth of a double nitrate reductase defective mutant of Arabidopsis thaliana: the importance of maintaining a high energy status
Impairments in leaf nitrogen (N) assimilation in C3 plants have been identified as processes conditioning photosynthesis under elevated [CO2], especially when N is supplied as nitrate. Leaf N status is usually improved ... -
Effect of including whole linseed and vitamin E in the diet of young bulls slaughtered at two fat covers on the sensory quality of beef packaged in two different packaging systems
Background: Forty-six Pirenaica young bulls, slaughtered at two levels of fatness (3 and 4 mm), were used to evaluate theeffect of the inclusion of 50 g kg−1 linseed alone or with 200 IU vitamin E kg−1 in the concentrate ... -
Quantitative proteomics reveals the importance of nitrogen source to control glucosinolate metabolism in Arabidopsis thaliana and Brassica oleracea
Accessing different nitrogen (N) sources involves a profound adaptation of plant metabolism. In this study, a quantitative proteomic approach was used to further understand how the model plant Arabidopsis thaliana adjusts ... -
Linkages between climate, seasonal wood formation and mycorrhizal mushroom yields
Fungi provide important forest ecosystem services worldwide. In Mediterranean pine forests, predicted warmer and drier conditions could lead to a decline in mushroom yields. Climate is a key factor regulating both tree ... -
Maintaining ecosystem function by restoring forest biodiversity: reviewing decision-support tools that link biology, hydrology and geochemistry
Not all forest models are applicable to a meta-modelling approach. Hence, the objective of the research presented here was to identify and compare the available forest models already being used in research, and to evaluate ... -
Actions for the restoration of the biodiversity of forest ecosystems in Cuba
The Earth is threatened daily by the degradation of its ecosystems due to fragmentation. One of the main consequences is biodiversity loss. Despite the economic progress and conservation actions carried out in many countries, ... -
Complex climate constraints of upper treeline formation in the Pyrenees
Alpine treelines are often induced by a threshold of minimum temperatures above which tree growth is generally not possible anymore. However, this worldwide pattern may not account for more drought-prone mountains, where ... -
Multimodel simulations of forest harvesting effects on long-term productivity and CN cycling in aspen forests
The effects of forest management on soil carbon (C) and nitrogen (N) dynamics vary by harvest type and species. We simulated long‐term effects of bole‐only harvesting of aspen (Populus tremuloides) on stand productivity ... -
Unravelling the mechanisms that improve photosynthetic performance of N₂-fixing pea plants exposed to elevated [CO₂]
Although the predicted enhanced photosynthetic rates of plants exposed to elevated [CO₂] are expected to increase carbohydrate and plant growth, recent findings have shown a complex regulation of these processes. The aim ... -
The CCAAT box-binding transcription factor NF-YA1 controls rhizobial infection
Symbiosis between legume plants and soil rhizobia culminates in the formation of a novel root organ, the 'nodule', containing bacteria differentiated as facultative nitrogen-fixing organelles. MtNF-YA1 is a Medicago ...
