Études de données issues de l'écologie participative : qualité et influence des protocoles

Abstract : Participatory sciences are used more and more as a support for scientific publications. This growing interest is encouraged by the education that highlight these programs. This is why the data quality from the participation of non-scientists as well as the used protocols impact is a new issue. We are trying here to set up a method to analyze this type of data. This approach is applied to biodiversity monitoring programs on terrestrial molluscs for three types of participants (general public, schools and farmers). Ecological indices are first highlighted and then questioned: the abundance and number of different morphological groups observed (diversity) for our taxon. These counts results comparison with reference data from scientific surveys or expert knowledge shows that the participants are able to respect a protocol but that the identification from determination keys to differentiate the morphological groups is more difficult. The most classic participatory ecology biases are then studied, such as the lack of snail-free observations or data entry errors. The comparison of our data sources allows us to think about solutions: participants training or other more common taxa presence in the forms. The observation areas are then studied and appear to be similar for gardens observations. The last step of our analysis is model establishment to highlight the variables that explain chosen ecological indices. This prediction is complicated for studied taxon, but nevertheless highlights trends which are for the most part interesting and in line with our ecological knowledge.
