The Great Pond Snail (Lymnaea stagnalis) is a fascinating freshwater gastropod mollusk that can be found in ponds, lakes, slow-moving rivers, and marshes across Europe, parts of Asia, and North America. (exploregoldcountry.com)
We've seen quite a few excellent laboratory studies over the years, beginning with Arthur (1982) on Lymnaea stagnalis and including notable contributions by Lam & Calow (1988) on L. peregra , DeWitt (1998) and Auld & Relyea (2011) on Physa , Hoverman & Relyea (2007) on Helisoma , Holomuzki & Biggs (2006) on the hydrobiids, and Urabe (1998) and Krist (2002) on the pleurocerids [1] .

This study investigated seasonal dynamics and environmental factors influencing occurrence and abundance of freshwater snail intermediate hosts in Tiko, a semi-urban endemic focus in the Mount Cameroon area. (bvsalud.org)
Lymnaeidae2
The Mazandaran Province with its temperate climate is a suitable place for living of snails, particularly lymnaeidae, that could have a significant role as an intermediate host of diseases. (scialert.net)
For here we see an elegant demonstration not just that the shell morphology of lymnaeid snails is subject to great phenotypic plasticity, but also that after all the environmental component of the variance is boiled away, at least some genetic component remains. (blogspot.com)
In this cross-sectional study, a total of 3,266 lymnaeid snails from 3 species were collected from different parts of streams, swamps, rice fields and rivers in the central areas of Mazandaran Province (Sari, Neka, Qaemshahr and Savad-Koh cities), during April to September, 2008. (scialert.net)
From the total of examined snails, 119 (3.6%) were found to be infected with the lymnaeid snails. (scialert.net)
Lymnaeid snails associated with larvae stages of Fasciolid sp. (scialert.net)
The aim of this study was to evaluate the occurance of trematodea infections in Lymnollect and recognize of lymnaeid snails using the crushing and emerging methods. (scialert.net)
This study was conducted on 3,266 lymnaeid snails in the central area of Mazandaran Province (Sari, Neka, Qaemshahr, Svad-koh cities) from April to September 2008, by a wooden handle paddle with 1.5 m long and net size of 30x30 cm. (scialert.net)
The continuous spread of planorbid snail hosts is a major concern. (bvsalud.org)
Aquatic2
Great Pond Snails are primarily aquatic creatures, preferring still or slow-moving freshwater bodies. (exploregoldcountry.com)

Species4
The Great Pond Snail is one of the larger snail species, with adult individuals typically reaching a size of about 1.5 to 2 inches (4-5 cm) in length. (exploregoldcountry.com)

After identification of species, each 1 to 2 snails were placed in a Petri-dish containing dechlorinated water and then, they were placed against light for 3 to 5 h or over night at room temperature. (scialert.net)
Genus2
But we follow Hubendick (1951) in preferring the inclusive genus Lymnaea , with Stagnicola a subgenus. (fwgna.org)
A genus of small freshwater snails of the order Pulmonata, found throughout Africa and the Middle East, where it is a vector of SCHISTOSOMA HAEMATOBIUM. (lookformedical.com)
Physa2
Last week I went down to my local pond and collected adults from the three most common pulmonate populations in the Charleston area - Lymnaea (Pseudosuccinea) columella , Physa acuta , and Helisoma trivolvis . (blogspot.com)
Ferrissia reaches maturity at a much smaller size than Lymnaea, Helisoma , or Physa , and hence one might not be surprised to discover they do not lay an egg "mass" at all. (blogspot.com)
Bulinus2
An understanding of the abundance and distribution of the Bulinus snail, intermediate host can inform strategic snail control programmes at a local scale. (bvsalud.org)
Water temperature, a rocky or sandy substrate type associated positively with Bulinus sp, meanwhile a higher water flow rate and medium vegetation negatively influenced the snail intermediate host population. (bvsalud.org)
Historically, sick horses were used as hosts for in vivo culture, while today medicinal leeches are bred in outdoor ponds on amphibian hosts or cultured in vitro using blood from slaughtered livestock. (ap24534inhibitor.com)
Shells2
The shells of these snails were found in lake marls in the southern part of the South Island. (wikipedia.org)
Brönmark opened his paper with a demonstration that Swedish populations of Lymnaea peregra/balthica [6] wild-collected from ponds with molluscivorous fish tend to bear lower spired, more rounded shells than populations inhabiting fishless ponds. (blogspot.com)
Populations2
Populations are most commonly found in wetlands, primarily inhabiting vernal ponds, weedy ditches, and the shallow margins of rivers and lakes (Stewart 2006). (fwgna.org)
populations originating in ponds with fish (filled diamonds in figure b) developing significantly wider second whorls than populations from fishless ponds (open squares). (blogspot.com)
Schistosomiasis1
These findings underscore the importance of timing behavioural and snail control interventions against schistosomiasis as well as increase vigilance of other trematode diseases in the study area. (bvsalud.org)
Hermaphroditic2
Great Pond Snails are hermaphroditic, which means each individual possesses both male and female reproductive organs. (exploregoldcountry.com)
Lymnaea provides a highly tractable model system that is well established in the learning and memory field for its uses in behavioral, electrophysiological, molecular and cellular network experimentation, allowing for both in vivo and in vitro approaches 14 . (nature.com)
Typically2
Lymnaea caperata is typically an inhabitant of more northern latitudes, ranging coast to coast from New York to California, north to through Alberta and south through Colorado (Baker 1928, Clarke 1981, Wu 1989, Jokinen 1992). (fwgna.org)
Faithful readers of this blog will not be surprised to learn that my email inbox typically receives a rather steady stream of inquiries with attached jpeg images of freshwater snails. (blogspot.com)
Stages3
Gastropods as indicators of trophic lake stages. (fwgna.org)
In Guilan Province, from the total of 4,830 different snails studied, only seven (0.35%) of L. gedrosiana were found to be infected with larvae stages of Fasciola sp. (scialert.net)
In contrast, Bin Dajem (2009) in his study revealed none trematode immature stages in different snails under study.The lack of comprehensive studies on these snails, especially in relation to rate of infection, in the Mazandaran Province, was the major factor for the decision to conduct the present study. (scialert.net)
Found1
Lymnaea gedrosiana were found to be infected with the Furcocercariae of Diplostomidae, Clinostomidae, Echinostomatidae and also cercariae of the Plagiorchiidae. (scialert.net)
Laboratory1

As a popular subject of study for biologists and nature enthusiasts alike, these snails boast a range of unique characteristics and behaviours. (exploregoldcountry.com)
Lymnaea caperata is pseudo-rare in our 17-state study area, FWGNA incidence rank I-1p . (fwgna.org)
Distribution1
Disease distribution is correlated to the distribution of the freshwater snails which in turn is influenced by the physicochemical status of the habitats. (mdpi.com)
Fish1
He then sampled snails from four ponds with fish and five fishless ponds and reared their three-week hatchlings (20 hatchlings per population) in two treatments for 12 weeks, with fish and without. (blogspot.com)
Individual1
I isolated individual snails in my standard 10 oz. plastic drinking cups, fed them green flake food, and over the following 48 hours, quite a few laid eggs. (blogspot.com)
Small1
To facilitate this, the snails surface periodically and extend a small snorkel-like tube, known as a 'pallial siphon,' to the water's surface to breathe. (exploregoldcountry.com)
