An increase in snake pipefish (Entelurus aequoreus) in the northeast Atlantic: possible causes and effects

Climate induced changes in the planktonic community have been reported in the North Atlantic in recent years (Beaugrand et al., 2002), and similar responses has been seen in higher trophic levels (eg fish, Brander et al., 2003). Many of these responses have been identified by the use of the Continuous Plankton Recorder (CPR), and here we discuss recent results from the survey concerning pipefish, numbers of which have increased dramatically around the UK in recent years. This has also been reported in both the scientific and popular press, and anecdotally by many divers. Pipefish are easily recognized, being vermiform with a long slender ‘snout’ and an armoured outer layer, much like an elongated seahorse. This increase has raised many questions, why has it happened and what affects will it have on the ecosystem?

Social networks and cooperative learning in a MOOC

MOOCs are changing the educational landscape and gaining a lot of attention in scientific literature. However, the pedagogical design of these proposals has been called into question. It is precisely MOOCs’ social aspect, i.e. the interaction between course participants and the support for learning processes that has become one of the main topics of interest. This article presents the results of a research project carried out at the University of the Basque Country, which focused in cooperative learning and the intensive use of social networks in a MOOC. Significant data was compiled through Likert-type surveys, revealing that the use of both external and internal social networks in a massive open online course is a factor that is evaluated positively by students. We argue that the use of social networks as a learning strategy in a MOOC has an influence on academic performance and on the students' success rate. Furthermore, the participants’ age also has a bearing on the social networks they use, and we have found that the younger members tend to work with external networks such as Twitter or personal blogs, whereas the older students are more inclined to use forums from the Chamilo or Ning platforms.

Pupil participation in school life: an approach from the educational community

The Convention on the Rights of the Child (CRC, 1989) is currently the most ratified international treaty. Several authors have highlighted its potential for both a moral education and citizenship. However, paradoxically, different studies report its limited or occasional incorporation into school practices. This article explores experiences of participation in schools,the third P of the CRC, from the plurality of voices and actors of the educational community,by means of 14 discussion groups in 11 autonomous communities in Spain. Discourse analysis evidence low levels of student participation in school life. But, at the same time, a favorable educational environment for the development of projects that contribute to child participation is found, as well as for the incorporation of the CRC as a mover and a referential integrator of the different schools projects. However, it is also an educational background conductive to projects for its development, such as the incorporation of the CRC as a referential integrator of the schools projects.
