Abstract: Citizen participation in online communities of scientific investigations has recently become more popular. Enhancing the engagement of citizens within these communities is a focus of attention for researchers and practitioners who want to amplify the impact on learning, science and society. This study investigates the relationship between engagement factors and behaviour patterns in an online community that requires high levels of citizen participation. While other studies explore engagement in communities where citizens contribute data, the current research investigates a community to support citizens in facilitating their own scientific investigations. Data were collected from log files and questionnaires, and multiple measures of engagement were examined: engagement metrics, roles, motivation, attitude, satisfaction and belonging to the community. The results allowed comparison of the engagement levels among different types of citizen participation communities and categorised members in engagement profiles, according to their behaviour patterns. Findings indicate a need for differing design approaches based on the type of citizen participation community and individual engagement profiles.

Summary: In Citizen Science, members of the general public collaborate with scientists to generate and use data relating to the natural world. For the many fields of marine research, this is a particularly powerful approach which should not be overlooked. The sheer scale of coastal and ocean environments mean that it would take several lifetimes for scientists to study them alone. By collaborating with citizens, a much greater number of people can be mobilized to gather a wealth of data and develop new scientific knowledge and understanding. The variety of data types which are amenable to Citizen Science, as outlined in the position paper, are great, meaning that there could be a project to suit everyone. Citizen Science can also enable participants to improve their Ocean Literacy, gain new skills and experiences, and can also empower them to participate in the process of delivering future marine policy.

Now, more than ever, marine science research is needed to understand the impacts of a world undergoing change. The rise of Marine Citizen Science to help address this need is therefore timely. This paper highlights opportunities, challenges and best practice in Marine Citizen Science, and sets out a list of high-level strategic recommendations for the future development of Marine Citizen Science in Europe. It presents examples of existing Marine Citizen Science initiatives in Europe to illustrate good practice. Common concerns such as data quality and maintaining engagement are discussed, as are future opportunities such as increased use of technology and potential role of Marine Citizen Science in informing marine policy and conservation. The paper closes with a list of high-level strategic recommendations for the future development of Marine Citizen Science in Europe.

Abstract: This paper presents an observatory for registering applications that use participatory sensing to collect data. Cataloging these applications will aid the scientific community to exchange more information, facilitating the comparison between different initiatives. Through an initial research, the applications are categorized in areas usually considered in the literature. We propose a survey to validate the platform and also discuss the taxonomies created as a result of this survey. The main contributions of this paper include the classification of crowdsensing applications in different ontological categories, as well as the proposal of a technology platform that enables the distributed and collaborative cataloging of crowdsensing initiatives.

Abstract: The validity of the threat status assigned to a species by the International Union for Conservation of Nature’s (IUCN) Red List relies heavily on the accuracy of the geographic range size estimate for that species. Range maps used to assess threat status often contain large areas of unsuitable habitat, thereby overestimating range and underestimating threat. In this study, we assessed 18 endemic birds of the Western Ghats to test the accuracy of the geographic range sizes used by the IUCN for their threat assessment. Using independently reviewed data from the world’s largest citizen science database (eBird) within a species distribution modeling framework, our results show that: (a) geographic ranges have been vastly overestimated by IUCN for 17 of the 18 endemic bird species; (b) range maps used by IUCN contain large areas of unsuitable habitat, and (c) ranges estimated in this study suggest provisional uplisting of IUCN threat status for at least 10 of the 18 species based on area metrics used by the IUCN for threat assessment. Since global range size is an important parameter for assigning IUCN threat status, citizen science datasets, high resolution and freely available geo-referenced ecological data, and the latest species distribution modeling techniques should be used to estimate and track changes in range extent whenever possible. The methods used here to significantly revise range estimates have important conservation management implications not only for endemic birds in the Western Ghats, but for vertebrate and invertebrate taxa worldwide.

Abstract: Changing land cover and climate regimes modify water quantity and quality in natural stream systems. In regions undergoing rapid change, it is difficult to effectively monitor and quantify these impacts at local to regional scales. In Vancouver, British Columbia, one of the most rapidly urbanizing areas in Canada, 750 measurements were taken from a total of 81 unique sampling sites representing 49 streams located in urban, forest, and agricultural-dominant watersheds at a frequency of up to 12 times per year between 2013 and 2016. Dissolved nitrate (NO3-N) and phosphate (PO4-P) concentrations, turbidity, water temperature, pH and conductivity were measured by citizen scientists in addition to observations of hydrology, vegetation, land use, and visible stream impacts. Land cover was mapped at a 15-m resolution using Landsat 8 OLI imagery and used to determine dominant land cover for each watershed in which a sample was recorded. Regional, seasonal, and catchment-type trends in measurements were determined using statistical analyses. The relationships of nutrients to land cover varied seasonally and on a catchment-type basis. Nitrate showed seasonal highs in winter and lows in summer, though phosphate had less seasonal variation. Overall, nitrate concentrations were positively associated to agriculture and deciduous forest and negatively associated with coniferous forest. In contrast, phosphate concentrations were positively associated with agricultural, deciduous forest, and disturbed land cover and negatively associated with urban land cover. Both urban and agricultural land cover were significantly associated with an increase in water conductivity. Increased forest land cover was associated with better water quality, including lower turbidity, conductivity, and water temperature. This study showed the importance of high resolution sampling in understanding seasonal and spatial dynamics of stream water quality, made possible with the large number of measurements taken with the help of trained volunteers. The results underscore the value of citizen science in freshwater research.

Abstract: Despite the growing volume of available transportation data and the efforts of many cities to increase cycling levels, there remains a lack of data on where people cycle. The use of GPS trajectories have now been used in cycle studies for several years, and more recently large, crowdsourced datasets of GPS recorded cycle trips have become available and of interest to transportation and planning departments. However, there is limited research on how representative these new crowdsourced data sources are of the general cycling population.

This study uses GPS trip data from a GPS data crowdsourcing project called the Bike Data Project. It prepares a dataset of GPS for the city of Lund, Sweden and matches the trips to a street network dataset. The study creates cycle counts based on the GPS trajectories for locations through the study area and compares these to manual counts made at the same location. No correlation was found between the counts, suggesting that the GPS trajectory data set is not a reliable representation of cycle trips within the study area, likely due to a lack of unique users within the dataset. The study plugs a gap in the current literature by quantitatively testing the accuracy of different map matching algorithms for matching cycling GPS data to the street network, by comparing them to ground truth trips of the actual routes taken, in the first example of this for cycle data. It is found that in certain situations in dense networks the matching cannot be relied upon to give the correct link, which could have implications for studies looking to quantify the percentage of cycling taking place on different road infrastructure types.

Abstract: Citizen science—the involvement of volunteers in data collection, analysis and interpretation—simultaneously supports research and public engagement with science, and its profile is rapidly rising. Citizen science represents a diverse range of approaches, but until now this diversity has not been quantitatively explored. We conducted a systematic internet search and discovered 509 environmental and ecological citizen science projects. We scored each project for 32 attributes based on publicly obtainable information and used multiple factor analysis to summarise this variation to assess citizen science approaches. We found that projects varied according to their methodological approach from ‘mass participation’ (e.g. easy participation by anyone anywhere) to ‘systematic monitoring’ (e.g. trained volunteers repeatedly sampling at specific locations). They also varied in complexity from approaches that are ‘simple’ to those that are ‘elaborate’ (e.g. provide lots of support to gather rich, detailed datasets). There was a separate cluster of entirely computer-based projects but, in general, we found that the range of citizen science projects in ecology and the environment showed continuous variation and cannot be neatly categorised into distinct types of activity. While the diversity of projects begun in each time period (pre 1990, 1990–99, 2000–09 and 2010–13) has not increased, we found that projects tended to have become increasingly different from each other as time progressed (possibly due to changing opportunities, including technological innovation). Most projects were still active so consequently we found that the overall diversity of active projects (available for participation) increased as time progressed. Overall, understanding the landscape of citizen science in ecology and the environment (and its change over time) is valuable because it informs the comparative evaluation of the ‘success’ of different citizen science approaches. Comparative evaluation provides an evidence-base to inform the future development of citizen science activities.

How can museums advance citizen science? The City Nature Challenge makes evident at least three themes: First, a belief that “science is open to all” is consistent with museums’ values of inclusivity and access. Second, museums know partnerships. (To realize this competitive bioblitz event, the California Academy of Sciences and the Natural History Museum of Los Angeles County enlisted a number of peer museums, NGOs, universities and colleges and other organizations across the U.S..) Third, museum workers strive to protect, interpret, and share resources that are held in the public trust, resources such as knowledge and nature that enrich public life and are the domain of the public sector. — AWA —

Excerpt: In its first year in 2016, a friendly nature challenge pitted Los Angeles and San Francisco in head-to-head competition that sent citizen scientists combing their backyards and local parks for urban wildlife. The idea is to recruit citizens — no training is necessary — to head out to see what they can find in nature, from worms to lizards to mountain lions.

“It’s a win-win for everybody,” said Lori Bettison-Varga, president and director of the Los Angeles County Natural History Museum. “Our researchers get data from places they can’t canvas, and Angelenos interact with the nature around them, make discoveries and collaborate with scientists.

“It conveys the idea that science is not a rarefied thing, it’s accessible to everyone, and it’s incredibly fun.”

Abstract: Life history trait analyses of non-native fishes help identify how novel populations respond to different habitat typologies. Here, using electric fishing and anglers as citizen scientists, scales were collected from the invasive barbel Barbus barbus population from four reaches of the River Severn and Teme, western England. Angler samples were biased towards larger fish, with the smallest fish captured being 410 mm, whereas electric fishing sampled fish down to 60 mm. Scale ageing revealed fish present to over 20 years old in both rivers. Juvenile growth rates were similar across all reaches. Lengths at the last annulus and Linfinity of the von Bertalanffy growth model revealed, however, that fish grew to significantly larger body sizes in a relatively deep and highly impounded reach of the River Severn. Anglers thus supplemented the scale collection and although samples remained limited in number, they provided considerable insights into the spatial demographics of this invasive B. barbus population.

One goal of citizen science is to encourage dissemination of citizen-made observations and knowledge gained about the interactions between the human-made and natural environments—even if that knowledge makes us uncomfortable in confronting  potentially damaging cultural traditions. Here we see something as seemingly innocent as a celebratory balloon release can have disastrous consequences. — LFF —

Excerpt: Matthew Bettelheim had seen one too many balloons, deflated and forgotten, lying around in nature. Doing field work in what seemed like remote locations throughout the San Francisco Bay Area, he’d find latex and Mylar balloons, or fragments of them, polluting places where they could pose a threat to wildlife.

They may be beautiful when they soar into the sky, but when they come back to earth, they can be deadly, Bettelheim said. Wildlife can mistake them for food. Once a balloon enters an animal’s digestive system, it can reduce food uptake, block the intestinal tract and cause the animal to slowly starve to death. Wildlife can also become tangled in the balloon material or the pretty ribbons attached to them, making them unable to move or feed, leading to stress, injury, malnutrition and eventually death.
