Great minds map alike: Citizen and expert distribution models of schistosome snail hosts in rural west Uganda

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Citizen scientists and an expert jointly monitor Biomphalaria snails (the intermediate host of Schistosoma mansoni) in rural areas of southwest Uganda, generating over 4500 georeferenced records. By comparing expert‐ and citizen‐based distribution models under perfect and imperfect detection, we demonstrate that site type and NDVI consistently ...
