Exclusion of Saccharomyces kudriavzevii from a wine model system mediated by Saccharomyces cerevisiae.
2010
This study investigated the competition and potential hybrid generation between the species Saccharomyces cerevisiae and S. kudriavzevii in a wine-model environment. Our main goal was to understand why S. kudriavzevii has not been found in wine fermentations whilst their hybrids are present. Auxotrophic mutants (Ura(-) and Lys(-)) were used to favour the selection of hybrids and to specifically differentiate the two species in mixed fermentations carried out at different temperatures (17 °C, 24 °C and 31 °C). Both yeasts showed a reduction in their maximum specific growth rates in mixed fermentations, indicating a clear antagonistic effect between the two microorganisms. Temperature played …
Ciencia de la Sostenibilidad: ¿Una nueva disciplina o un nuevo enfoque para todas las disciplinas?
2015
Al inicio de este siglo XXI comenzó a desarrollarse un nuevo dominio científico, la Ciencia de la Sostenibilidad, con el objetivo explícito de hacer frente a la actual situación de emergencia planetaria e impulsar la transición a sociedades sostenibles. Una nueva forma de hacer ciencia para un nuevo período de la historia de la humanidad, el Antropoceno, en el que el planeta está experimentando grandes cambios, debidos principalmente a la acción de los seres humanos, que amenazan la supervivencia de la propia especie humana. Nuestro propósito en este trabajo ha sido analizar en qué medida esta Ciencia de la Sostenibilidad puede realmente contribuir a la necesaria transición a la Sostenibili…
Dioecious species and arbuscular mycorrhizal symbioses: the case of Antennaria dioica.
2013
Sex-specific interactions with herbivores and pollinators have been observed in female and male plants of dioecious species. However, only a limited number of studies have revised sex-specific patterns in mycorrhizal symbiosis. To test whether female and male plants of Antennaria dioica differ in their relationship with arbuscular mycorrhizal (AM) fungi, we examined the temporal and spatial variation in AM fungi in female, male and non-reproductive A. dioica plants in three natural populations in Finland during flowering and after seed production. Our results are consistent with previous studies both under greenhouse and field conditions with the same species showing differences in AM colon…
Sobre los límites de la intervención de los servicios sociales
2018
Uno de los argumentos más comunes a la hora de justificar el exiguo impacto d elos servicios sociales es el escaso peso que éstos representan en el conjunto del gasto social. En el articulo se muestra que esta justificación puede no ser del todo cierta. Pese a que el balance de sus primeros años fue claramente positivo, el análisis de ciertos datos del periodo 1997-2007 previos al estallido de la crisis muestra, a juicio del autor, las crecientes dificultades para mejorar las situaciones de pobreza y exclusión social con independencia de los medios financieros y personales que se hayan dispuesto. Tal afirmación sugiere la posibilidad de que la intervención de los servicios sociales esté som…
Zein as biodegradable material for effective delivery of alkaline phosphatase and substrates in biokits and biosensors
2016
A biodegradable material, zein, is proposed as a reagent delivery platform for biokits and biosensors based on alkaline phosphatase (ALP) activity/inhibition in the presence of phosphatase substrates. The immobilization and release of both the substrate and/or the active ALP, in a biodegradable and low-cost material such as zein, a prolamin from maize, and in combination with glycerol as plasticizer have been investigated. Three zein-based devices are proposed for several applications: (1) inorganic phosphorus estimation in water of different sources (river, lake, coastal water and tap water) with a detection limit of 0.2mg/L - compared to at least 1mg/L required by legislation, (2) estimat…
Sexualidad en diversidad funcional intelectual: recopilación de los instrumentos de evaluación del equipo Salusex
2021
La sexualidad de las personas con discapacidad intelectual (DI) ha sido un tema muy controvertido. Su sexualidad ha estado sustentada por una serie de mitos y falsas creencias que, a pesar de carecer de apoyo empírico, han restringido su derecho a conseguir una expresión libre de esta faceta. En unos casos su sexualidad ha sido equiparada a la de los niños, creyendo que eran personas asexuadas; y en otros se les ha presupuesto una ausencia de control sobre sus impulsos, optando por no despertar sus instintos sexuales. El equipo SALUSEX inició el estudio de la sexualidad en este colectivo en el año 2015 con un proyecto financiado por el Ministerio de Economía y Competitividad relacionado con…
Gene expression is stronger associated with behaviour than with age and fertility in ant workers
2018
AbstractThe ecological success of social insects is based on division of labour, not only between queens and workers, but also among workers. Whether a worker tends the brood or forages is strongly influenced by age, fertility and nutritional status, with brood carers being younger, more fecund and corpulent. Here, we experimentally disentangle behaviour from age and fertility inTemnothorax longispinosusant workers and analyse how these parameters are linked to whole-body gene expression. Our transcriptome analysis reveals four times more genes associated with behaviour than with age and only few fertility-associated genes. Brood carers exhibited an upregulation of genes involved in lipid b…
Religiosity and meditation practice : Exploring their explanatory power on psychological adjustment
2019
There has been increased interest in the relationships between religiosity, meditation practice and well-being, but there is lack of understanding as to how specific religious components and distinct meditation practices could influence different positive and negative psychological adjustment outcomes. The aim of this study was to assess the explanatory power of religious beliefs and the practice of prayer, focused attention (FA), open monitoring (OM), and compassion meditation (CM) on psychological adjustment, taking into consideration a number of practice-related variables such as session length, frequency of practice and lifetime practice. Psychological adjustment was assessed by means o…

Data from: Multi-modal defenses in aphids offer redundant protection and increased costs likely impeding a protective mutualism
2018
1.The pea aphid, Acyrthosiphon pisum, maintains extreme variation in resistance to its most common parasitoid wasp enemy, Aphidius ervi, which is sourced from two known mechanisms: protective bacterial symbionts, most commonly Hamiltonella defensa, or endogenously encoded defenses. We have recently found that individual aphids may employ each defense individually, occasionally both defenses together, or neither. 2.In field populations, Hamiltonella-infected aphids are found at low to moderate frequencies and while less is known about the frequency of resistant genotypes, they show up less often than susceptible genotypes in field collections. To better understand these patterns, we sought t…
