Seasonal and spatial patterns of infestation with ectoparasitic mites on New Zealand geckos revealed using a crowd-sourced citizen science database

Abstract

The advent of online crowd-sourced nature databases provides an opportunity to yield information about ecological interactions on a scale not previously possible. In particular, such databases provide an opportunity to collate information on host–parasite interactions through screening photographs of hosts. Using photographs from iNaturalist we expanded the known hosts for ectoparasitic mites in New Zealand geckos from 9 to 20 host species, including the first report of ectoparasitic mites on geckos from the genus Toropuku. Additionally, spatial and seasonal variation in mite prevalence was investigated, giving deeper insight in the possibilities of analysing crowd-sourced datasets.
