Using citizen science data to estimate climatic niches and species distributions

Opportunistic citizen data documenting species observations – i.e. observations collected by citizens in a non-standardized way – is becoming increasingly available. In the absence of scientific observations, this data may be a viable alternative for a number of research questions. Here we test the ability of opportunistic species records to provide predictions of the realized […]

The influence of motivational factors on the frequency of participation in citizen science activities

Citizen science has become a mainstream approach to collect information and data on many different scientific subjects. In this study, we assess the effectiveness of engagement and meaningful experience of participants in citizen science projects. We use motivational measures calculated from a web survey where respondents answered questions regarding to their motivation to participate in […]

Spatial distribution of citizen science casuistic observations for different taxonomic groups

Opportunistic citizen science databases are becoming an important way of gathering information on species distributions. These data are temporally and spatially dispersed and could have limitations regarding biases in the distribution of the observations in space and/or time. The authors tested the influence of landscape variables in the distribution of citizen science observations for eight […]
