Вплив низьких концентрацій іонів цинку на розмір середньодобового раціону ставковиків (Mollusca: Pulmonata: Lymnaeidae) [PDF]

open access: yes, 2011
Встановлено вплив концентрацій іонів цинку 0,5 ГДКр та ГДКр на розмір середньодобового раціону 10 видів молюсків роду Lymnaea за споживання ними листя частухи. Виявлено, що низькі концентрації іонів Zn2+ у всіх без винятку досліджених молюсків стимулюють

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components

open access: yesFreshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

The effect of isolation on the life-history traits of Pseudosuccinea columella (Pulmonata: Lymnaeidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 2001
A population of Pseudosuccinea columella was raised under laboratory conditions and its life tables were determined in isolated and paired snails. Isolated snails were significantly larger in shell size than paired snails from five weeks of age onward ...

The cercariae of trematodes developing in mollusks of the family Lymnaeidae Rafinesque, 1845 from the waterbodies in the basin of the river Syrdarya

open access: yesРоссийский паразитологический журнал, 2016
The results of the study of the fauna of trematode cercaria, which develop in Lymnaeidae, in the region are presented. Parthenitae and cercariae are recorded in seven species of the genus Lymnaea: L. auricularia, L. truncatula, L. stagnalis, L. corvus, L.

Secuenciación del ITS-1 del ADN ribosomal de Galba truncatula (Gastropoda, Lymnaeidae) y su impacto potencial en la transmisión de la fascioliasis en Mendoza, Argentina [PDF]

open access: yes, 2006
Sequencing of the rDNA ITS–1 proved that the lymnaeid snail species Galba truncatula is present in Argentina and that it belongs to the haplotype HC, the same as that responsible for the fascioliasis transmission in the human hyperendemic area with the ...

Evaluating the In Vitro Anthelmintic Activity of Zinc Oxide Nanoparticles (ZnO‐NPs) Against the Adult Stages of Fasciola hepatica

open access: yesVeterinary Medicine and Science, Volume 11, Issue 1, January 2025.
Resistance to currently deployed flukicide is a growing health problem. This study evaluated the in vitro anthelmintic activity of zinc oxide nanoparticles (ZnO‐NPs) at 0.05, 0.10 and 0.12 mg/mL against Fasciola hepatica. The fastest mortality and paralysis rates of flukes were obtained at 0.12 mg/mL of ZnO‐NPs. Furthermore, SEM results showed complete

When One Global Invasion Hides Another—Cryptic Interspecific Invasion in Freshwater Gastropods

open access: yesDiversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Cryptic invasions are an understudied phenomenon among species invasions, especially in freshwater invertebrates. We study the gastropod family Physidae, including the global invaders Physella acuta and several enigmatic Stenophysa species, their phylogenetic relationships and the presence of native species among African Physidae. We infer
