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.

There is growing recognition that effective science communication should not merely focus on addressing scientific literacy but must also open dialogue between scientists and the public, build trust, and increase public interest in environmental research. Citizen science BioBlitzes offer a useful approach for science communicators to address many of these key aims. We explore the BioBlitz concept, learnings and outcomes based on a case study of a BioBlitz held in Sydney, Australia. We found that participants valued learning about biodiversity on the day and importantly, all participants (scientists and citizen scientists) rated interacting and learning from the experience as one of the main benefits.

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.

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.

This issue forms Part II of JCOM's collection of articles and essays exploring the field of citizen science. Here I introduce the articles in Part II, outlining how they contribute to our understanding of the ways that volunteers participate in citizen science projects, what motivates this participation and what learning arises as a result of participation.

Community-based water monitoring (CBWM) provides essential baseline information on watershed health and engages the public in science, but those involved often encounter barriers to informing environmental management. We conducted qualitative interviews with watershed group coordinators and government counterparts from four CBWM organizations to explore instances where CBWM successfully influenced governmental decision-making. Our findings show that the level of rigor for quality standards, inclusion of volunteers, available resources, and desired goals are important considerations when designing community-based monitoring programs. Integrated program designs that include adequate quality standards and engage volunteers are more apt to maximize resources and realize both scientific and educational goals.

The participation of non-professionally trained people in so-called citizen science (CS) projects is a much discussed topic at the moment. Frequently, however, the contribution of citizens is limited to only a few narrow tasks. Focusing on an initiative dedicated to the study of the human microbiome, this paper describes such a case where citizen participation is limited to the provision of funding, samples, and personal data. Researchers opted for a crowdsourced approaches because other forms of funding and recruitment did not seem feasible. We argue that despite the narrow understanding of participation in the context of some CS projects, they can address some of the democratic concerns related to scientific knowledge creation. For example, CS and crowdsourcing can help to foster dialogue between researchers and publics, and increase the influence of citizens on research agenda setting.

While the use of scientific visualisations (such as brain scans) in popular science communication has been extensively studied, we argue for the importance of popular images (as demonstrated in various talks at #POPSCI2015), including pictures of everyday scenes of social life or references to pictures widely circulating in popular cultural contexts. We suggest that these images can be characterised in terms of a rhetorical theory of argumentation as working towards the production of evidentiality on the one hand, and as aiming to link science to familiar visualities on the other; our example is da Vinci's "Vitruvian Man".

This commentary considers the topics of humour and online settings. Both have received increasing attention amongst researchers and practitioners of science communication, and both raise numerous questions around the role of informality and enjoyment in the spread of information. However, online settings also provide a great range of data with which to address these questions. Here I suggest that close consideration of technical infrastructure plays an important role in this data collection. I shall do so using case studies drawn from two popular participatory websites, reddit and Facebook, which display contrasting attitudes towards using humour. I argue that these attitudes are partly products of the different tools provided by the pages for users to show appreciation, which affect the appearance of content on the websites. I also suggest that these tools allow users to appreciate jokes in multiple ways, and by extension might provide researchers with methods for assessing different forms of engagement.

Interest in the possible role for comedy as a medium for communicating and engaging the public in science is growing. However, current research has so far been restricted to exploring whether the content of scientific knowledge is accurate and precise within comedy, and whether the public might be said to understand science better for having watched it. In this commentary, I suggest that this approach neglects the diversity with which scientific ideas and images are used in comedy, particularly when comedy is written without the explicit goal of communicating science. I present my current research on the American animated comedy South Park, which suggests a different story: science serves to expose the hypocrisy and self-interest that governs the town. I suggest that examples such as South Park might benefit the analysis of comedy and science, by seeking to explain the very presence of science in comedy and in doing so, explore the values attributed to science within popular culture.
