First evidence of a genetic basis for thermal adaptation in a schistosome host snail

open access: yesEcological Monographs, Volume 95, Issue 1, February 2025.
Abstract Freshwater snails play a key role in the transmission of schistosomiasis, a tropical parasitic disease affecting over 150 million people. Adaptation of these snails to local climatic conditions is a critical factor in determining how climate change and other environmental factors influence disease transmission dynamics, yet this potential ...

Detailed Early Life History of the Giant Muricid Snail Chicoreus ramosus in the Southern China Sea

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Tropical marine life is highly diverse, but the development and utilization of many species remain insufficient. The giant muricid snail Chicoreus ramosus, notable for its large size and high‐quality meat, holds significant potential for aquaculture. Previous descriptions of its seedling production were incomplete and sometimes inaccurate.

The Heterobranchia -a new concept of the phylogeny of the higher Gastropoda

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2009
Abstract In an attempt to reconstruct the phylogeny of the higher gastropods, the essential characters are first critically examined to determine occurrence and systematic value. From here the evolutionary pathway is cladistically analysed from a common prosobranch ancestor up to the basal pulmonates.
