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 ...

Trematode Infection Prevalence Increases With Snail Richness: Observations From a 4‐Year Study of Snail–Trematode Interactions

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We find that higher snail richness correlated with increased overall and generalist trematode infections, while specialist infections showed a similar but nonsignificant trend. The study also highlighted potential host‐switching events and the impact of long‐term sampling on parasite communities, emphasizing the need for continued monitoring of host ...

Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

Journal of Fish Biology, Volume 107, Issue 3, Page 837-850, September 2025.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Pharmacological Inhibition of c‐Jun N‐Terminal Kinase Activity Exacerbates Liver Damage in Schistosoma mansoni Infected Mice

Liver International, Volume 45, Issue 9, September 2025.
ABSTRACT Background and Aims Schistosomiasis is a neglected tropical disease affecting more than 250 million people worldwide. Eggs of the parasitic helminth S. mansoni cause major morbidity in the liver, spleen and intestine. Of note, egg‐released soluble antigens (SEA) induce the transcription factor c‐Jun in hepatocytes, promoting hepatocellular ...
