Festuca hystrix Boiss. y Festuca reverchonii Hackel en la Península Ibérica

Intrapopulation genome size dynamics in Festuca pallens.

BACKGROUND AND AIMS It is well known that genome size differs among species. However, information on the variation and dynamics of genome size in wild populations and on the early phase of genome size divergence between taxa is currently lacking. Genome size dynamics, heritability and phenotype effects are analysed here in a wild population of Festuca pallens (Poaceae). METHODS Genome size wa...

Newsgames: Nuevas Tendencias en el Periodismo Ibérico

El fenómeno de la gamificación en España ha cobrado un papel principal en los nuevos modelos de negocios. Durante los últimos años las estrategias de ludificación han comenzado a aplicarse con éxito en múltiples sectores, incluidos los del periodismo y la comunicación. En el siguiente artículo exponemos las cuestiones sobre las que se sustentan estos nuevos modelos periodísticos y señalamos los...

Aprendizaje Automático versus Expresiones Regulares en la Detección de la Negación y la Especulación en Biomedicina

In this paper, we present a machine learning system that identify the negation and speculation signals in biomedical texts, in particular, in the BioScope corpus. The objective of this research is to compare the efficiency of this approach focused on machine learning with which it is based on regular expressions. Among the systems that follow the latter approach, we used NegEx because of its av...

Exploiting repetitive sequences and BAC clones in Festuca pratensis karyotyping

The Festuca genus is thought to be the most numerous genus of the Poaceae family. One of the most agronomically important forage grasses, Festuca pratensis Huds. is treated as a model plant to study the molecular mechanisms associated with tolerance to winter stresses, including frost. However, the precise mapping of the genes governing stress tolerance in this species is difficult as its karyo...
