The temperature dimension of the seed germination niche in fen wetlands
Get PDFThe seed germination niche partly determines adaptation, ecological breadth and geographic range in plant species. In temperate wetlands environmental temperature is the chief regulator of germination timing, but the ecological significance of high and low temperatures during dormancy break and germination is still poorly understood. Our aim was to characterize the temperature dimension of the germination niche in mountain base-rich fens, determining (1) the effect of different temperatures on dormancy break and germination, and (2) whether different germination strategies may be identified at the species level. We conducted laboratory germination experiments with seeds of 15 species from these habitats, collected in 18 fen sites in the Cantabrian Mountains (Spain) for two consecutive years. In all the species the seeds were totally or conditionally dormant at dispersal and stratification produced a significant increase of germination. In most cases there was not an obligatory requirement for cold temperatures during dormancy break, since warm stratification promoted germination as well. Although the optimal germination thermoperiod was generally high (30/20ºC), most species could also germinate at lower temperatures after cold-stratification. We also identified a group of species associated to cold-water springs that germinated only at low temperatures. Our results demonstrate that dormancy break in mountain base-rich fens does not obligatorily depend on cold temperatures during overwintering. Furthermore, germination at cool temperatures may be more widespread in wetland habitats than previously thought. The existence of two distinctive germination strategies, ‘warm’ and ‘cool’, can potentially give rise to divergent species responses to climate change
La atención centrada en la persona. Algunas claves para avanzar en los servicios gerontológicos
Get PDFThe aim of this paper is twofold: (1) to present the Person Centred Care approach (PPC) from the perspective of how it can be applied to the gerontology resources and (2) to provide a few hints on how to facilitate its development. First, this paper lists the guidelines that lead the application of the
PPC approach to the elderly in a frail and/or dependant situation. Secondly, the paper reviews the origin of this approach, as well as its main contributions and the initiatives that have been carried
out both in Spain and internationally. Thirdly, it deals with the factors that can facilitate the implementation of the PPC approach into the services and proposes a number of phases that can bring progress in the implementation process. Then, it analyses the extent to which the PPC approach has been developed in the Spanish gerontology services where, in the last few years, there has been an increasing interest in this approach. Lastly, this paper points out some of the current challenges and
risks but also the benefits that this approach brings.FUNDACIÓN CASER PARA LA DEPENDENCIAEl objetivo de este artículo es realizar una aproximación al enfoque de la Atención Centrada en la Persona (ACP) en los recursos gerontológicos así como señalar algunas claves para facilitar su aplicación. En primer lugar se enuncian los principios que orientan este enfoque en la atención a
las personas mayores en situación de fragilidad o dependencia. Posteriormente se revisa su origen así como las principales aportaciones e iniciativas llevadas a cabo en el ámbito internacional y en
España. Seguidamente se abordan los factores y elementos que facilitan su implementación en los
centros y servicios, proponiendo algunas fases para su desarrollo. Finalmente se analiza el momento de desarrollo de la ACP en España en cuanto a los servicios gerontológicos señalando algunos de los
principales retos y riesgos que en la actualidad han de ser tenidos en cuenta y se destacan los beneficios que reporta este enfoque de la atenció

La paratuberculosis bovina : Diágnostico y control
No full textLa paratuberculosis es una enfermedad infecciosa crónica causada por una
bacteria denominada Mycobacterium avium paratuberculosis (Map), que afecta
tanto a rumiantes domésticos como silvestres, en los que provoca una enteritis
y linfadenitis granulomatosa.Se cree que los animales se infectan
en edades tempranas y solo algunos
llegan a desarrollar la enfermedad en la
edad adulta, que es cuando se observa
un adelgazamiento progresivo, diarrea y finalmente la muerte de los animales
afectados. La principal vía de transmisión
entre los animales es la fecal-oral, a través
de la ingestión de bacilos en el agua,
leche o cualquier alimento contaminado
por las heces de los animales infectados

Hybrid Cooperative Coevolution for Fuzzy Flexible Job Shop Scheduling Problems
No full textIn this paper we consider a variant of the flexible job shop scheduling problem with uncertain task durations modelled as fuzzy numbers. We propose a cooperative coevolutionary algorithm to minimise the schedule's makespan, with two di fferent populations evolving the two main aspects that conform a solution: machine assignment and task relative order. Additionally, we incorporate a specifi c local search method for each population. The resulting hybrid algorithm, called CELS, is then evaluated on existing benchmark instances, comparing favourably with the state-of-the-art methods.Gobierno de España (FEDER TIN2010-20976-C02-02 and MTM2010-16051)EUROFUSE'2013 Workshop on Imprecision and Uncertainty in Preference Modeling and Decision Makin
