Researchers have identified a range of motives for participation in citizen science projects, but have not investigated their relative efficacy in encouraging initial participation. We report on an experiment (N=36,513) that compared the response to emails designed to appeal to four different motives for participation. We found that the messages appealing to the possibility of contributing to s...

Species distribution models relate the geographic occurrence pattern of a species to environmental features and are used for a variety of scientific and management purposes. One source of data for building species distribution models is citizen science, in which volunteers report locations where they observed (or did not observe) sets of species. Since volunteers have variable levels of experti...

The contributions of everyday individuals to significant research has grown dramatically beyond the early days of classical birdwatching and endeavors of amateurs of the 19 century. Now people who are casually interested in science can participate directly in research covering diverse scientific fields. Regarding astronomy, volunteers, either as individuals or as networks of people, are involve...

Citizen science is quickly becoming one of the most effective tools for the rapid and low-cost collection of environmental information, filling a long recognized gap in in-situ data. Incentivizing citizens to participate, however, remains a challenge, with gaming being widely recognized as an effective solution to overcome the participation barrier. Building upon well-known gaming mechanics, ga...

Approaching citizen science discourse as a form of epideictic rhetoric, in this paper I explore how scientists are rhetorically constituted through public-facing communication by five Ontario-based organizations involved water quality monitoring initiatives. Working from the perspective that it is important to consider both macro-level (ideo)logics frame these initiatives well their situated di...

Citizen science is part of a wider trend in and society promoting two-way dialogue engagement between scientists the public, by involving citizens research process. This paper examines how CONCISE, an international project Spain, Italy, Portugal, Poland Slovakia, seeks to understand acquire use scientific information, engaging through public consultations. The consultations gathered close 500 2...

All known examples of generic 3D bar-and-joint frameworks where the distance between a non-edge pair is implied by the edges in the graph contain a rigid vertexinduced subgraph. In this paper we present a class of arbitrarily large graphs with no non-trivial vertex-induced rigid subgraphs, which have implied distances between pairs of vertices not joined by edges. As a consequence, we obtain (a...

An initial classifier considers the main frequency component of the call, centered around 13.5 kHz and spanning mainly between 11 and 17 kHz. The ratio between this and a range where little noise is present (8–9 kHz) is a measure of the acoustic energy of the cicada call, as can be defined as: • Only cicada native to the UK • Only present in the New Forest • High pitched call at ~ 13.5 kHz • Di...
