Citizen science projects, which entail scientific work undertaken by members of the public, have increased substantially over the last three decades. However, the credibility of such science has been questioned, especially with respect to its prospects for producing peer-reviewed publications, the principal means by which science is communicated and validated. We conducted a meta-analysis of 895 citizen science projects launched between 1890 and 2018. Three-quarters (674) did not produce a single peer-reviewed paper. The remaining 221 projects produced 2075 publications, although just five projects accounted for nearly half the publications. The average time from project launch to first publication was 9.15 years. Projects in health and medicine and astronomy were most likely to produce publications. Projects in biology (65.8% of all projects), computer science, and social sciences were least likely to publish their results. In conclusion, the “science” element of most citizen science projects is largely irrelevant as it is never validated or communicated. We propose reclassifying citizen science projects into two types: (i) Citizen Science, where the focus is on science, and participants essentially function as sampling devices; and (ii) Citizen Engagement, where the value lies more in citizen engagement than it does in citizen science.

Photographs are widely used to visualise science. However, the influence of visual quality of photographs on the effectiveness of science communication is often disregarded and seldom tested. This study examines how the visual quality of photographs affects science communication on interpretive signage within Xixi National Wetland Park, China. Results show that a high-quality photograph on the signage significantly increased the following affective and cognitive aspects of communication: (1) a visitor’s intention to read the signage, (2) enjoyment of reading the interpretive information, (3) understanding and (4) recall of the information on the signage. This study offers empirical evidence for the benefits of using high-quality photographs to visualise science. To improve the effectiveness of science communication in interpretive products, we argue that the quality of the selected photographs should be considered seriously.

This proof‐of‐concept study investigates the potential of immersive 360° VR nature videos to enhance emotional well‐being and nature connectedness, focusing on their use as e‐health interventions within social marketing initiatives. The research examined four key variables: (i) presence, or the extent to which participants felt immersed in the VR experience; (ii) emotional responses, measured by changes in participants' positive and negative affect; (iii) user experience, including enjoyment and engagement; and (iv) nature connectedness, reflecting participants' state of connection to the natural world. Using a mixed‐method approach, participants (n = 63) engaged with four VR nature videos, with presence, emotional states and nature connectedness measured before and after the experience. Results showed high levels of presence, with participants reporting feelings of calmness, escape and connection to nature. Positive affect increased post‐VR, although negative affect remained unchanged. Nature connectedness improved across all participants, highlighting the potential of VR nature experiences to support well‐being. Individual differences, such as prior VR experience and gender, influenced perceptions, emphasising the need to tailor interventions. This study provides a foundation for using 360° VR nature videos in social marketing to promote emotional well‐being, particularly for those with limited access to natural environments.

To explore what types of photographs are more helpful means to interpret natural attractions within national parks, this study focused on the relationship between the photographs with different visual characteristics and their perceived visual appeal. A photograph-based Q method was adopted. Results confirmed the visual quality of a photograph was the most important characteristic that determined its perceived attractiveness; those photographs with a high visual quality could successfully attract tourists’ attention. The subject also significantly affected the preferences of observers, suggesting an interest-dependent pattern. Using photographs of birds as examples, the participants who were interested in birds were attracted by the photographs of birds rather than those of other subjects. This study provides a better understanding of the effectiveness of photographs for communication. Findings may help researchers, communicators and national park marketers better understand and select appropriate photographs for interpretation within national parks.

Erect-crested penguins are the least studied of all penguins. They breed on two isolated subantarctic island groups, the Antipodes and Bounty Islands. Sporadic nest counts indicate a dramatic decline in numbers of erect-crested penguins over the last 50 years. Here we present data from a study undertaken in 1998 on the breeding biology, behavior and hormones of erect-crested penguins. It represents, even today, by far the most detailed data available on this species. The penguins exhibited extreme reversed egg-size dimorphism, whereby the first-laid A-egg was much smaller than the second-laid B-egg. A-eggs were lost before (42.3%) or on (37.8%) the day the B-egg was laid, and none survived more than 7 days after that. The penguins were in a low state of reproductive readiness, as evidenced by low levels of copulation, fighting, and testosterone in males during the courtship/laying period when, curiously, plasma levels of testosterone were at least as high in females. The laying interval (5.4 days) is the longest recorded for any penguin species, and incubation was highly variable until clutch completion. Most nests (91.2%) contained no nesting material and eggs were laid directly onto the ground. A-eggs were lost mainly by rolling out of the nest. However, even when prevented from doing so by an experimental manipulation, A-eggs survived no longer than those in control nests. Testosterone levels in males increased after clutch completion, when they remained in attendance at the nest for up to 13 days, despite females assuming most of the incubation duties. The bills of males were significantly larger than those of females and probably help with guarding the nest. We discuss explanations for obligate brood reduction in crested penguins and the options for conservation in light of our census results, which indicate that this enigmatic penguin species could be in trouble.

We presented 867 participants with one of two videos about climate change that differed only in terms of whether they had an infotainment or expository narration. They were available in either English or Spanish. The participants consisted of two distinct clusters: one in which all were over 30 with a university degree, and another dominated by younger participants without a university degree. The infotainment version produced a significantly reduced perception of the seriousness of climate change for the planet in the latter cluster. Furthermore, viewers of the English versions, who were predominantly residents in countries with low-context cultures, perceived the risk of climate change for the planet to be significantly higher after watching the video with the expository narration. Using infotainment for science communication is a two-edged sword: while it may help engagement, making light of a topic can reduce perceptions about its seriousness. We suggest that the use of infotainment should be determined by the aims of the communicators and the nature of the target audience. If the purpose is simply to convey information, then infotainment is likely to be the most effective and it has the additional benefit of engaging recipients that lack a university education. However, if the purpose is to affect attitudes and persuade an audience, then an expository narration is likely to be most effective.
