Ongoing Evolution in the Genus Crocus: Diversity of Flowering Strategies on the Way to Hysteranthy
2021
[EN] Species of the genus Crocus are found over a wide range of climatic areas. In natural habitats, these geophytes diverge in the flowering strategies. This variability was assessed by analyzing the flowering traits of the Spanish collection of wild crocuses, preserved in the Bank of Plant Germplasm of Cuenca. Plants of the seven Spanish species were analyzed both in their natural environments (58 native populations) and in common garden experiments (112 accessions). Differences among species observed in the native habitats were maintained under uniform environmental conditions, suggesting a genetic basis for flowering mechanisms. Two eco-morphological types, autumn- and spring-flowering …
A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint
2021
[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture. Ad…
The Monaco Agreement on the Conservation of Cetaceans of the Black Sea, Mediterranean Sea and Contiguous Atlantic Area
1999
Dedico este trabajo a comentar el Acuerdo sobre la conservación de los cetáceos del Mar Negro, del Mar Mediterráneo y de la Zona Contigua del Atlántico, adoptado en Mónaco el 24 de Noviembre de 1996. Se presta una atención especial a los orígenes de la adopción de este acuerdo internacional y a sus relaciones con el Convenio sobre la conservación de especies migratorias de animales silvestres (Bonn, 23 de junio de 1979). La parte nuclear de este trabajo examina los objetivos principales del Acuerdo de Mónaco, las medidas nacionales y regionales previstas para alcanzar estos objetivos, así como los procedimientos e instituciones responsables del deber de adoptar estas medidas. Se realizan un…
La diversidad biológica en el Derecho Internacional
2011
Análisis de los principales instrumentos jurídicos internacionales de ámbito mundial dedicados a la protección o a la conservación de la diversidad biológica. Se presta una especial atención al Convenio de Naciones Unidas sobre la diversidad biológica de 1992.
Protected areas and species: the Mediterranean Basin
1995
Éste es un estudio de Derecho internacional sobre la protección de zonas y especies en el Mar Mediterráneo. En este trabajo examino los tratados internacionales relativos a zonas especialmente protegidas y a la diversidad biológica que son aplicables en el Mar Mediterráneo. Tras una breve introducción, en la sección II analizo aquellos tratados internacionales que en esta materia son aplicables al Mar Mediterráneo, aunque expresamente no se limitan sólo al mismo. En la sección III, realizo una mención especial al enfoque y a la evolución que, sobre estas materias, se contienen en los instrumentos mediterráneos de naturaleza tanto política como jurídica. This is an International Law study on…

Effect of Chitin Whiskers on the Molecular Dynamics of Carrageenan-Based Nanocomposites
2019
[EN] Films of carrageenan (KC) and glycerol (g) with different contents of chitin nanowhiskers (CHW) were prepared by a solution casting process. The molecular dynamics of pure carrageenan (KC), carrageenan/glycerol (KCg) and KCg with different quantities of CHWs as a filler was studied using dielectric relaxation spectroscopy. The analysis of the CHW effect on the molecular mobility at the glass transition, T-g, indicates that non-attractive intermolecular interactions between KCg and CHW occur. The fragility index increased upon CHW incorporation, due to a reduction in the polymer chains mobility produced by the CHW confinement of the KCg network. The apparent activation energy associated…
A comprehensive RNA-Seq-based gene expression atlas of the summer squash (Cucurbita pepo) provides insights into fruit morphology and ripening mechan…
2021
[EN] Background Summer squash (Cucurbita pepo: Cucurbitaceae) are a popular horticultural crop for which there is insufficient genomic and transcriptomic information. Gene expression atlases are crucial for the identification of genes expressed in different tissues at various plant developmental stages. Here, we present the first comprehensive gene expression atlas for a summer squash cultivar, including transcripts obtained from seeds, shoots, leaf stem, young and developed leaves, male and female flowers, fruits of seven developmental stages, as well as primary and lateral roots. Results In total, 27,868 genes and 2352 novel transcripts were annotated from these 16 tissues, with over 18,0…
Brewer's spent grains as biofuels in combustion-based energy recovery processes: Evaluation of thermo-oxidative decomposition
2022
[EN] The high global generation of wastes and side streams from agri-food production has led to environmental impact and causes nature degradation due to their uncontrolled management. These wastes are profitable materials with significant economic value that could otherwise be exploited as new sources in the feed industry or the production of bioenergy. Among them, brewer¿s spent grain (BSG) is a solid by-product generated in the beerbrewing process that consists of the barley grain husks together with parts of the pericarp and seed coat layer. Although it is rich in fibres and proteins, its main use is currently limited to animal feed or simply deposition to landfills. This study pursues …
Connecting the data landscape of long-term ecological studies: the SPI-Birds data hub
2021
The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and eco-logical processes in the wild. Furthermore, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad-scale global issues (e.g. climate change).
