Significant Progress in the Study of African Freshwater Snails Over the Past 260 Years

Ecology and Evolution, Volume 15, Issue 2, February 2025.
Globally, freshwater ecosystems are threatened, and studies estimate rapid degradation compared with terrestrial and marine ecosystems. Like most other tropical regions, Africa still has far to go regarding discovery and documentation. Using a systematic review process, we evaluated freshwater African snail studies.

Limnic gastropods and trematodes of public health concern in Barreirinhas, Maranhão State, Brazil [PDF]

Brazilian Journal of Biology
Limnic gastropods are of great importance as both biodiversity components and public health threats. These organisms serve as vectors for some helminths that may be involved in the occurrence of human zoonoses.

Schistosomiasis Interventions in Africa: Assessment and Systematic Review

Journal of Parasitology Research, Volume 2025, Issue 1, 2025.
Background: Schistosomiasis is a neglected tropical disease with high endemicity across Africa. As a waterborne parasitic disease, the population at highest risk includes school‐age children, although adults are also affected. The rationale for this review is to assess the effectiveness of the various schistosomiasis control interventions implemented ...

Multi‐Environment Quantification of Parasite and Intermediate Host DNA on Pasture for Fine‐Scale Disease Risk Assessment

Environmental DNA, Volume 6, Issue 5, September–October 2024.
Environmental DNA (eDNA) isolated from multiple environmental sources were used to better assess location suitability for parasite and snail intermediate host species in agricultural settings. ABSTRACT Parasite transmission occurs in complex environments comprising multiple matrices.

Distribution, abundance, population structures, and potential impacts of the invasive snail, Tarebia granifera in aquatic ecosystems of north‐eastern South Africa

Ecology and Evolution, Volume 14, Issue 6, June 2024.
The study investigates Tarebia granifera, a highly successful aquatic invader, in South Africa's Limpopo and Phongolo River systems. The study revealed that T. granifera dominates in habitats where it is present, negatively impacting native molluscan species. Interestingly, the study did not find significant correlations between T.

Procambarus virginalis Lyko, 2017: A new threat to Iberian inland waters

Ecology and Evolution, Volume 14, Issue 5, May 2024.
We provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...
