Ciberseguridad : el reto del siglo XXI
El siglo XXI es el siglo del dato, su anĂĄlisis y de la conectividad;
en definitiva, el siglo de la informaciĂłn en tiempo real y disponible
para cualquiera en cualquier lugar del mundo. Dichos datos estĂĄn
impactando en todos los ĂĄmbitos de la sociedad y de la economĂa
de tal forma que no se entiende ningĂșn sector productivo ni
ninguna relaciĂłn social sin dato; todos tenemos algĂșn lugar en las
redes sociales desde donde intercambiamos experiencias personales
o profesionales. Si a este hecho se le suma el auge de la
Inteligencia Artificial, se tiene un siglo en el que los avances tecnolĂłgicos
van a ser totalmente disruptivos para todos nosotros

Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins
Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota. Generalized linear models showed that a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability. Increases in TDI were explained through a significant increase in toxin variants such as MC-YR, anatoxin and cylindrospermopsin, accompanied by a decreasing presence of MC-LR. While global warming continues, the direct and indirect effects of increased lake temperatures will drive changes in the distribution of cyanobacterial toxins in Europe, potentially promoting selection of a few highly toxic species or strains.Peer reviewe
Traditional knowledge hiding in plain sight â twenty-first century ethnobotany of the ChĂĄcobo in Beni, Bolivia
Abstract Background The ChĂĄcobo are a Panoan speaking tribe of about 1000 members (300+ adults) in Beni, Bolivia. Originally nomadic, the ChĂĄcabo were relocated to their current main location in the 1960s. Researchers have visited the ChĂĄcabo since 1911. A first more detailed anthropological report exists from the late 1960s, and ecologicalâethnobotanical studies were conducted in the 1980s and 1990s. The presented work represents a complete ethnobotanical inventory of the entire adult ChĂĄcobo population, with interviews and plant collection conducted directly by ChĂĄcobo counterparts. Methods Based on previous reports and our preliminary studies, we hypothesized that twenty-first century ChĂĄcobo plant use centered on income generation, and that traditional plant use related to household utensils, medicine and traditional crop varieties had almost disappeared. To test this hypothesis, we started the âChĂĄcobo Ethnobotany Project,â training 10 indigenous ChĂĄcobo participants in ethnobotanical interview and plant collection techniques, in order to more fully document ChĂĄcobo knowledge and avoid the influence of foreign interviewers. Results Our study found 331 useful plant species in 241genera of 95 plant families, with leaves, roots and bark being the most commonly used plant parts The comprehensive documentation that these methods enabled completely nullified our initial hypothesis of knowledge loss. Traditional crop varieties are still widely grown and traditional knowledge is alive. Moreover, it is being actively recuperated in certain domains by the younger generation. Most ChĂĄcobo know, and can name, traditional utensils and tools, although only the older generation has still the skills to manufacture them. While many ChĂĄcobo still know the names and uses of medicinal species, the younger generation is however often unsure how to identify them. Conclusions In this paper we illustrate the complexity of perspectives on knowledge at different ages, and the persistence of knowledge over almost a century. We found that traditional knowledge was only partially affected by the processes of exposure to a market economy, and that different knowledge domains experienced different trends as a result of these changes. Overall knowledge was widely distributed, and we did not observe a directional knowledge loss. We stress the importance to not directly conclude processes of knowledge loss, cultural erosion or acculturation when comparing the knowledge of different age groups
Who should conduct ethnobotanical studies? Effects of different interviewers in the case of the ChĂĄcobo Ethnobotany project, Beni, Bolivia
Abstract Background That the answers elicited through interviews may be influenced by the knowledge of the interviewer is accepted across disciplines. However, in ethnobotany, there is little evidence to quantitatively assess what impact this effect may have. We use the results of a large study of traditional ecological knowledge (TEK) of plant use of the ChĂĄcobo and Pacahuara of Beni, Bolivia, to explore the effects of interviewer identity and knowledge upon the elicited plant species and uses. Methods The ChĂĄcobo are a Panoan speaking tribe of about 1000 members (300+ adults) in Beni, Bolivia. Researchers have collected anthropological and ethnobotanical data from the ChĂĄcobo for more than a century. Here, we present a complete ethnobotanical inventory of the entire adult ChĂĄcobo population, with interviews and plant collection conducted directly by ChĂĄcobo counterparts, with a focus on the effects caused by external interviewers. Results Within this large study, with a unified training for interviewers, we did find that different interviewers did elicit different knowledge sets, that some interviewers were more likely to elicit knowledge similar to their own, and that participants interviewed multiple times often gave information as different as that from two randomly chosen participants. Conclusions Despite this, we did not find this effect to be overwhelmingâthe amount of knowledge an interviewer reported on the research subject had comparatively little effect on the amount of knowledge that interviewer recorded from others, and even those interviewers who tended to elicit similar answers from participants also elicited a large percentage of novel information
Stratification strength and light climate explain variation in chlorophyll a at the continental scale in a European multilake survey in a heatwave summer
To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across the Mediterranean, Continental, and Boreal climatic zones of the European continent. Multilinear regression models tested on this snapshot of mostly eutrophic lakes (median total phosphorus [TP] = 0.06 and total nitrogen [TN] = 0.7 mg L-1), and its subsets (2 depth types and 3 climatic zones), show that light climate and stratification strength were the most significant explanatory variables for chlorophyll a (Chl a) variance. TN was a significant predictor for phytoplankton biomass for shallow and continental lakes, while TP never appeared as an explanatory variable, suggesting that under high TP, light, which partially controls stratification strength, becomes limiting for phytoplankton development. Mediterranean lakes were the warmest yet most weakly stratified and had significantly less Chl a than Boreal lakes, where the temperature anomaly from the long-term average, during a summer heatwave was the highest (+4 degrees C) and showed a significant, exponential relationship with stratification strength. This European survey represents a summer snapshot of phytoplankton biomass and its drivers, and lends support that light and stratification metrics, which are both affected by climate change, are better predictors for phytoplankton biomass in nutrient-rich lakes than nutrient concentrations and surface temperature.Peer reviewe
