Volunteer water quality monitors represent the intersection between citizen science and environmental stewardship. Understanding what motivates participation will enable project managers to improve recruitment and retention. This survey of 271 volunteers from eight water quality monitoring organizations in the U.S. found the strongest motivators to participate are helping the environment or community and contributing to scientific knowledge. No variation by gender was found, but younger volunteers have different motivations and preferences than older volunteers. Volunteers value the communication of tangible results more than recognition or reward.

Despite the rapid expansion of citizen-based monitoring, data from these programs remain underutilized by natural resource managers, perhaps due to quality and comparability issues. We present the Bosque Ecosystem Monitoring Program as a case study of an initiative successfully meeting long-term monitoring needs of federal, state, tribal, and local natural resource managers, and informing public policy. To maximize potential for partnerships with managers, we recommend the creation of a five-year plan including scientific goals and financial solvency strategies prior to establishing a citizen science program, and offering multiple platforms for data-sharing and dialogue.

Online citizen science projects have demonstrated their usefulness for research, however little is known about the potential benefits for volunteers. We conducted 39 interviews (28 volunteers, 11 researchers) to gain a greater understanding of volunteers' motivations, learning and creativity (MLC). In our MLC model we explain that participating and progressing in a project community provides volunteers with many indirect opportunities for learning and creativity. The more aspects that volunteers are involved in, the more likely they are to sustain their participation in the project. These results have implications for the design and management of online citizen science projects. It is important to provide users with tools to communicate in order to supporting social learning, community building and sharing.

In recent years, citizen science has gained popularity not only in the scientific community but also with the general public. The potential it projects in fostering an open and participatory approach to science, decreasing the distance between science and society, and contributing to the wider goal of an inclusive society is being explored by scientists, science communicators, educators, policy makers and related stakeholders. The public's participation in citizen science projects is still often reduced to data gathering and data manipulation such as classification of data. However, the citizen science landscape is much broader and diverse, inter alia due to the participation opportunities offered by latest ICT. The emergence of new forms of collaboration and grassroots initiatives is currently being experienced. In an open consultation process that led to the "White Paper on Citizen Science for Europe", the support of a wide range of project types and innovative forms of participation in science was requested. In this paper we argue for mechanisms that encourage a variety of approaches, promote emerging and creative concepts and widen the perspectives for social innovation.

The academic journal paper has been around for several hundred years and during that time has seen shifts in style and structure. This editorial explores the traditional research paper and considers whether thinking about the research paper as a story, provides insights into style and structure that would make research both more transparent and more readable.

The prevalent lack of research on the interrelations between science, research and popular culture led to the organization of the first International Conference on Science and Research in Popular Culture #POPSCI2015, which took place at Alpen-Adria-Universität in Klagenfurt, Austria, from 17--18 September 2015. The aim of the conference was to bring together not only science communication researchers with an interest in popular culture, but also other scholars, scientists and researchers, artists, media professionals and members from the general public. In this issue of JCOM we present four invited commentaries which are all based on presentations at the conference.

As a result of the large number of media used and a variety of objectives pursued by the various Public Communication of Science (PCS) activities, their evaluation turns into a daunting task. Therefore, a general taxonomy for all the approaches used by PCS could be helpful in order to differentiate their effects and to measure their results. A general format is proposed for a fast and easy evaluation of PCS efforts and to share a common language with all science communicators, who need to easily compare the results of this growing activity.

Non-invasive prenatal testing (NIPT) is an emerging technology for detecting chromosomal disorders in the fetus and mass media may have an impact on shaping the public understanding of its promise and challenges. We conducted a content analysis of 173 news reports to examine how NIPT was portrayed in English-language media sources between January 1 and December 31, 2013. Our analysis has shown that media emphasized the benefits and readiness of the technology, while overlooking uncertainty associated with its clinical use. Ethical concerns were rarely addressed in the news stories, which points to an important dimension missing in the media discourse.

Interviews were conducted with 110 marine users to elicit their salient beliefs about recording marine species in a citizen science project. The results showed that many interviewees believe participation would increase knowledge (either scientific, the community's, or their own). While almost half of the interviewees saw no negative outcomes, a small number expressed concerns about targeting of marine species by others, or restrictions on public access to marine sites. Most of the people surveyed (n = 106) emphasised the importance of well-designed technological interfaces to assist their data collection, without which they would be unlikely to engage in the project.

Mirror neurons (MN) — or neurons said to be able to "mirror" the sensed environment — have been widely popularized and referenced across many academic fields. Yet, MNs have also been the subject of considerable debate in the neurosciences. Using a criterion based sampling method and a citation analysis, this paper examines the extent of engagement with the neuroscience literature about MNs, looking specifically at the frequency of "MN debate sources" within articles published in the JSTOR and Communication and Mass Media (CMMC) databases. After reporting the results, the paper reviews characteristic examples in context and, ultimately, shows that MN debates remain largely absent from peer-reviewed articles published in JSTOR and CMMC. However, the paper suggests that this happens for good reason and that MNs retain the potential for inventive animations even though debates have gone largely unrecognized.
