This paper presents a long-term study on how the public engage with discussions around citizen science and crowdsourcing topics. With progress in sensor technologies and IoT, our cities and neighbourhoods are increasingly sensed, measured and observed. While such data are often used to inform citizen science projects, it is still difficult to understand how citizens and communities discuss citizen science activities and engage with citizen science projects. Understanding these engagements in greater depth will provide citizen scientists, project owners, practitioners and the generic public with insights around how social media can be used to share citizen science related topics, particularly to help increase visibility, influence change and in general and raise awareness on topics. To the knowledge of the authors, this is the first large-scale study on understanding how such information is discussed on Twitter, particularly outside the scope of individual projects. The paper reports on the wide variety of topics (e.g., politics, news, ecological observations) being discussed on social media and a wide variety of network types and the varied roles played by users in sharing information in Twitter. Based on these findings, the paper highlights recommendations for stakeholders for engaging with citizen science topics.

AbstractRecent studies suggest insect declines in parts of Europe; however, the generality of these trends across different taxa and regions remains unclear. Standardized data are not available to assess large-scale, long-term changes for most insect groups but opportunistic citizen science data is widespread for some taxa. We compiled over 1 million occurrence records of Odonata (dragonflies and damselflies) from different regional databases across Germany. We used occupancy-detection models to estimate annual distributional changes between 1980 and 2016 for each species. We related species attributes to changes in the species’ distributions and inferred possible drivers of change. Species showing increases were generally warm-adapted species and/or running water species while species showing decreases were cold-adapted species using standing water habitats such as bogs. We developed a novel approach using time-series clustering to identify groups of species with similar patterns of temporal change. Using this method, we defined five typical patterns of change for Odonata – each associated with a specific combination of species attributes. Overall, trends in Odonata provide mixed news – improved water quality, coupled with positive impacts of climate change, could explain the positive trend status of many species. At the same time, declining species point to conservation challenges associated with habitat loss and degradation. Our study demonstrates the great value of citizen science data for assessing large-scale distributional change and conservation decision-making.

Meaningful Data

AbstractCommingled and fragmentary remains are found in numerous contexts worldwide. These assemblages typically require large scale, long term study to fully extract and contextualize meaningful data. However, when uncovered in CRM and foreign settings where remains cannot leave their country of origin, there is a need for quick, reliable data collection. Presented here is a recording system for use in field- and research-based laboratory settings. Utilizing visual forms and a minimal set of observations for skeletal elements from the cranium to the foot, the database facilitates data collection of fragment identification, age at death and sex estimation, dental observations, trauma recording, and taphonomic observations. A data dictionary is also provided, with definitions and value lists used in the database itself. The database has been used in field labs throughout the old world and by numerous researchers who have modified it to meet their own research needs. By presenting a minimal standard of data in a highly adaptable database, the recording system described here provides consistent baseline data in a user-friendly, quick-access format

A large-scale, long-term study is being conducted to describe the bird assemblages inhabiting a 6500 ha area at Booderee National Park, south-eastern Australia. In this paper, we provide a list of birds recorded within rainforest, forest, woodland, shrubland, heathland and sedgeland during surveys conducted each spring between 2003 and 2007. Of particular interest was the contrast between the birds of sites burned in a wildfire in 2003 and sites that remained unburned. We recorded a total of 103 species from 35 families. We found that after the major fire, the vast majority of individual species and the bird assemblage per se in most vegetation types recovered within two years. Exceptions occurred in structurally simple vegetation types such as sedgeland and wet heathland in which reduced levels of species had not returned to pre-fire (2003) levels by 2007.
