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 ...

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...
