Epidemiological situation and molecular identification of cercarial stage in freshwater snails in Chao-Phraya Basin, Central Thailand

open access: yesAsian Pacific Journal of Tropical Biomedicine, 2016
Objective: To investigate the prevalence of cercarial trematode infection in snails and to examine the reconstruction of the phylogenetic relationship to explain the molecular system of cercarial stage trematodes to estimate the infection rate of in the ...

MOLLUSK OF THE FAMILY BITHYNIIDAE (GASTROPODA, LITTORINIMORPHA) OF THE LOWER VOLGA PLAINS RIVER

open access: yesIzvestiya of Samara Scientific Center of the Russian Academy of Sciences, 2022
Background. Preservation of stable and sustainable natural conditions in aquatic ecosystems of various territories is the most urgent problem of nature management in many regions of the world. Occurring changes together with the anthropogenic factor intensify the processes of destabilization of watercourse biocenoses.

How can eDNA contribute in riverine macroinvertebrate assessment? A metabarcoding approach in the Nalón River (Asturias, Northern Spain)

open access: yesEnvironmental DNA, Volume 1, Issue 4, Page 385-401, November 2019., 2019
Rivers are impacted ecosystems that need to be monitored regularly. Here, we have tested a metabarcoding approach to compare the results on water quality monitoring with conventional assessments for benthic macroinvertebrates. Water quality monitoring in freshwaters using macroinvertebrate eDNA performs equally well than conventional morphological ...

Transferência do gênero monotípico Parodizia Medina de Bithyniidae (Gastropoda, Prosobranchia) para Pyramidellidae (Gastropoda, Heterobranchia) [PDF]

open access: yesRevista Brasileira de Zoologia, 2004
Propõe-se a transferência do gênero monitípico Parodizia Medina, 1959 de Bithyniidae (Prosobranchia) para Pyramidellidae (Heterobranchia). A proposta está baseada em dados morfológicos de espécimens de P. uruguayensis Medina, 1959 procedentes da bacia do rio Tramandaí, Rio Grande do Sul, Brasil.

Land‐use in Europe affects land snail assemblages directly and indirectly by modulating abiotic and biotic drivers

open access: yesEcosphere, Volume 10, Issue 5, May 2019., 2019
Abstract Type and intensity of land‐use vary in space and time and strongly contribute to changes in richness and composition of species communities. In this study, we examined land snail communities in forests and grasslands in three regions of Germany.

Morphological Characterization of Emerging Cercariae among Lymnaeid Snails from Barangay Cawongan, Padre Garcia, Batangas, Philippines

open access: yesJournal of Parasitology Research, Volume 2018, Issue 1, 2018., 2018
Background and Objectives. Lymnaeid snails are the known intermediate hosts of the liver fluke Fasciola spp. and therefore play an important role in the parasite’s life cycle. The study is conducted to determine specificity of snail host‐parasite interaction and to determine the snail‐trematode infection rate by cercarial emergence, characterizing the ...

BITHYNIA SHAPKAREVI N.SP., A NEW SPECIES FROM PRESPA LAKE, R. MACEDONIA (GASTROPODA: BITHYNIIDAE)

open access: yesEcologica Montenegrina, 2015
From Macedonia only Bithynia prespensis Hadžišče, 1963 is known so far. Recent investigations in Prespa Lake revealed a new Bithynia species, Bithynia shapkarevi n. sp. which is described here. Holotype and a paratype in addition to the penis morphology are depicted. The new Bithynia species has been compared with all known Bithynia spp.

Modeling Aquatic Macroinvertebrate Richness Using Landscape Attributes

open access: yesInternational Journal of Ecology, Volume 2015, Issue 1, 2015., 2015
We used a rapid, repeatable, and inexpensive geographic information system (GIS) approach to predict aquatic macroinvertebrate family richness using the landscape attributes stream gradient, riparian forest cover, and water quality. Stream segments in the Allegheny River basin were classified into eight habitat classes using these three landscape ...

Declines in Freshwater Mussels and Loss of Mussel–Invertebrate Interactions in the Subtropical Waterbodies of Dhaka, Bangladesh

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 11, November 2024.
ABSTRACT Freshwater mussels are a globally threatened taxon, but little is known about population trajectories for species outside Europe and North America. To contribute to understanding of mussel conservation status outside these regions, we surveyed mussel and other invertebrate populations in waterbodies across Dhaka, Bangladesh, to assess ...
