Involvement of protein kinase C in 5-HT-stimulated ciliary activity in Helisoma trivolvis embryos. (1/997)

1. During development, embryos of the pulmonate gastropod, Helisoma trivolvis, undergo a rotation behaviour due to the co-ordinated beating of three bands of ciliated epithelial cells. This behaviour is in part mediated by the neurotransmitter serotonin (5-HT) released from a pair of identified embryonic neurons. Using time-lapse videomicroscopy to measure ciliary beat frequency (CBF) in response to pharmacological manipulations, we determined whether protein kinase C (PKC) is involved in mediating 5-HT-stimulated ciliary beating. 2. Diacylglycerol (DAG) analogues sn-1,2-dioctanoyl glycerol (DiC8; 100 microM) and 1-oleoyl-2-acetyl-sn-glycerol (OAG; 100 microM), partially mimicked the 5-HT-induced increase in CBF. In contrast, application of OAG in the absence of extracellular Ca2+ did not result in an increase in CBF. 3. 5-HT-stimulated CBF was effectively blocked by PKC inhibitors bisindolylmaleimide (10 and 100 nM) and calphostin C (10 nM). In addition, bisindolylmaleimide (100 nM) inhibited DiC8-induced increases in CBF. At a higher concentration (200 nM), bisindolylmaleimide did not significantly reduce 5-HT-stimulated cilio-excitation. 4. Two different phorbol esters, phorbol 12-myristate 13-acetate (TPA; 0.1, 10 or 1000 nM) and phorbol 12beta, 13alpha-dibenzoate (PDBn; 10 microM) did not alter basal CBF. TPA (1 microM) did not alter 5-HT-stimulated CBF. Likewise, the synthetic form of phosphatidylserine, N-(6-phenylhexyl)-5-chloro-1-naphthalenesulphonamide (SC-9; 10 microM), did not increase CBF, whereas a strong increase in CBF was observed upon exposure to 5-HT. 5. The results suggest that a DAG-dependent, phorbol ester-insensitive isoform of PKC mediates 5-HT-stimulated CBF in ciliated epithelial cells from embryos of Helisoma trivolvis.  (+info)

Vaccination with cathepsin L proteinases and with leucine aminopeptidase induces high levels of protection against fascioliasis in sheep. (2/997)

The potential of different parasite proteinases for use as vaccine candidates against fascioliasis in sheep was studied by vaccinating animals with the cathepsin L proteinases CL1 and CL2 and with leucine aminopeptidase (LAP) purified from adult flukes. In the first trial, sheep were immunized with CL1 or CL2 and the mean protection levels obtained were 33 and 34%, respectively. Furthermore, a significant reduction in egg output was observed in sheep vaccinated either with CL1 (71%) or with CL2 (81%). The second trial was performed to determine the protective potential of the two cathepsin L proteinases assayed together, as well as in combination with LAP, and of LAP alone. The combination of CL1 and CL2 induced higher levels of protection (60%) than those produced when these enzymes were administered separately. Those sheep that received the cocktail vaccine including CL1, CL2, and LAP were significantly protected (78%) against metacercarial challenge, but vaccination with LAP alone elicited the highest level of protection (89%). All vaccine preparations induced high immunoglobulin G titers which were boosted after the challenge infection, but no correlations between antibody titers and worm burdens were found. However, the sera of those animals vaccinated with LAP contained LAP-neutralizing antibodies. Reduced liver damage, as assessed by the level of the liver enzyme gamma-glutamyl transferase, was observed in the groups vaccinated with CL1, CL2, and LAP or with LAP alone.  (+info)

Characterization of a cDNA encoding a precursor polypeptide of a D-amino acid-containing peptide, achatin-I and localized expression of the achatin-I and fulicin genes. (3/997)

Achatin-I and fulicin, isolated from the ganglia and atria of the giant land snail Achatina fulica, are a tetrapeptide and pentapeptide containing a d-Phe and d-Asn at position 2, respectively. We succeeded in cloning a cDNA encoding a precursor of achatin-I from the Achatina ganglia, revealing that the d-Phe present in achatin-I is coded by a common l-Phe codon, TTT or TTC. The deduced polypeptide was found to comprise seven repeats of the achatin sequence GFAD and one analog GFGD flanked on both sides by the typical endoproteolytic site KR. Northern blot analysis of transcripts and Southern blot analysis of reverse transcription (RT)-PCR products demonstrated that achatin-I mRNA was localized in the subesophageal ganglia, whereas expression of fulicin mRNA was detected in the atrium as well as in the subesophageal ganglia. Furthermore, localization of the achatin gene transcript in the right and left pedal ganglia compartments was shown by in situ hybridization on sections of subesophageal ganglia, whereas the fulicin transcript was observed in the right and left parietal ganglia. These data suggested that achatin-I plays an essential role in the regulation of the heart as a neurotransmitter or neurohormone through production in the pedal ganglia and transport to the atrium, whereas fulicin serves not only as a neurotransmitter or neurohormone but also as a novel atrial hormone.  (+info)

Binding of carbon monoxide to alpha-hemocyanin and beta-hemocyanin from Helix pomatia. (4/997)

The binding of carbon monoxide to alpha and beta-hemocyanin from the snail Helix pomatia was studied under equilibrium conditions. Homotropic interactions upon carbon monoxide binding were much weaker than upon the binding of oxygen. Heterotropic interactions (Bohr effect and calcium-ion effect), however, were just as strong as in the case of the binding of oxygen. For alpha-hemocyanin a linkage has been observed between the binding of carbon monoxide and a change in quaternary structure of the protein.  (+info)

A special pattern of the smooth endoplasmic reticulum in the kidney of the snail Cryptomphalus aspersa. (5/997)

A special structural pattern of the smooth endoplasmic reticulum (SER) has been observed in the kidney of the snail Cryptomphalus aspersa. Two types of cells (clear and dark) cover the foldings of the renal sac; the dark cells are by far the most numerous. A cisterna of SER enveloping the nucleus appears invariably in both types of cells, with no disruptions, or small ones (from 50 to 90 nm) along its profile. The layer of cytoplasm lodged between the external nuclear membrane and this cisterna is found invariably to be from 0-20 to 0-25 mum in width. Glycogen is abundant in the cytoplasm as alpha particles, and also in the nucleus, but as beta particles. It is noteworthy that absolutely no glycogen is present in the layer of cytoplasm lodged between the nuclear membrane and the surrounding SER envelope. Long profiles of SER are also observed closely approaching and parallel to the plasma membrane of the dark cells. Considering the role of SER in glycogen metabolism in the kidney of the snail, the possible function of these cisternae as a support system ofr enzymes involved in the metabolism of glucides is discussed.  (+info)

Karyotypes on three species of Chinese mesogastropod snails, Semisulcospira libertina, S. dolichostoma and Viviparus rivularis. (6/997)

Three species of the families Viviparidae and Pleuroceridae, the first intermediate host of paragonimiasis, metagonimiasis and echinostomiasis were studied cytologically. The observed diploid chromosome number was as follows: Semisulcospira libertina 36, S. dolichostoma 34, and Viviparus rivularis 64. The mitotic chromosome complement of S. libertina has nine metacentric pairs and nine submetacentric pairs, and S. dolichostoma has three metacentric pairs and 14 submetacentric pairs of chromosomes. Viviparus rivularis showed two metacentric pairs and 30 submetacentric pairs of chromosomes.  (+info)

Macromolecular antimicrobial glycoprotein, achacin, expressed in a methylotrophic yeast Pichia pastoris. (7/997)

A cDNA encoding achacin, an antimicrobial glycoprotein from the body surface mucus of giant African snail Achacina fulica Ferussac, was expressed in a methylotrophic yeast, Pichia pastoris, and recombinant achacin (rAch) was secreted in yeast minimal medium in a polyglycosylated form with 80 kDa. Carbohydrate analysis revealed that the glycosylated moiety of rAch was composed of 50 mol mannose and 2 mol N-acetylglucosamine residues. Antimicrobial activity using Escherichia coli and Staphylococcus aureus showed that the rAch had a behavior similar to its native counterpart. The rAch showed so wide an antimicrobial spectrum that 0.1 mg/ml rAch inhibited the growth of Pseudomonas fluorescens, Staphylococcus epidermidis, and Streptococcus faecalis in addition to E. coli and S. aureus, whereas it did not appreciably affect the growth of Proteus mirabilis, Bacillus cereus and Micrococcus luteus. The rAch was also effective in preventing growth of Vibrio anguillarum and Vibrio parahaemolyticus. The results suggested that the rAch had great potential of using as an antimicrobial agent.  (+info)

Osmoregulation and FMRFamide-related peptides in the salt marsh snail Melampus bidentatus (Say) (Mollusca: Pulmonata). (8/997)

The pulmonate snail Melampus bidentatus occupies the high intertidal zone of salt marshes in a nearly terrestrial environment. The hemolymph osmolarity of the snails collected in the field paralleled that of the adjacent water and was affected by the tides and precipitation. The snails initially gained or lost weight when submerged in hypo- or hyperosmotic media, respectively, but returned to their original weight after 24 h. The content of their immunoreactive (IR)-FMRFamide-Related Peptides (FaRPs) was measured in various tissues by radioimmunoassay, and IR-FaRPs were found in every tissue analyzed. The subesophageal part of the central nervous system (CNS) contained more IR-FaRPs than the supraesophageal part, and the kidney and the tissues of the reproductive tract contained more than other peripheral tissues. The levels of IR-FaRPs in the CNS, kidney, and hemolymph were higher in snails that were immersed in higher concentrations of seawater. Many IR neurons are present in all ganglia of the CNS except the pleural ganglia, and IR neurites are extensively distributed within the CNS and its connective tissue sheath. The visceral nerve from the visceral ganglion is immunoreactive and could be seen to innervate the kidney, which contains IR-varicosities. An osmoregulatory role for the FaRPs is suggested.  (+info)

The giant African snail (Achatina fulica) secretes mucus for crawling and protection from moisture loss and pathogenic infections. The snail mucus has been popularly used as a bioactive reagent in medical and cosmeceutical products. This study observed the distribution of pedal mucous cells of A. fulica and the snail growth effect (1-3 mth) on pedal mucus production and the types of mucous cells. Foot tissues were processed using a paraffin technique and stained with Massons trichrome, periodic acid Schiff, and periodic acid Schiff-Alcian Blue at pH 2.5. Visualization under a light microscope showed that the pedal mucus of A. fulica was mainly produced from two types of mucous glands: 1) tubular mucous gland cells located on the dorsal part of foot that produced acid mucopolysaccharide mucus; and 2) round mucous gland cells located on the ventral part of foot that produced acid and neutral mucopolysaccharide mucus. A positive correlation between the acid mucin level and snail age was only ...
FOR INFORMATION AND ACTION. DA-2013-55 December 23, 2013 Subject: APHIS Establishes Additional Regulated Area in Florida for Giant African Snail (Lissachatina fulica, formerly Achatina fulica) To: State and Territory Agricultural Regulatory Officials The Animal and Plant Health Inspection Service (APHIS) is notifying stakeholders of a new regulated area for giant African snail (GAS) in Miami-Dade County, Florida. Program personnel recently detected GAS in one residential area outside of existing regulated areas in Miami. The revised map and description of the new regulated areas are posted on the APHIS website at . In September 2011, APHIS confirmed the detection of GAS, Lissachatina fulica, in a residential area of Miami, Florida. GAS is one of the most damaging snails in the world because it is known to consume at least 500 different plants including vegetables, fruits, and ornamental crops. Since the ...
Several species of exotic snails are serious pests of plants and threats to public health.. Scientists consider the giant African snail, Lissachatina fulica, to be one of the most damaging snails in the world. It is known to eat at least 500 different types of plants, including breadfruit, cassava, cocoa, papaya, peanut, rubber, and most varieties of beans, peas, cucumbers, and melons. Believed to be originally from East Africa, L. fulica has established itself throughout the IndoPacific Basin, including the Hawaiian islands. This mollusk has also been introduced to the Caribbean islands of Martinique and Guadeloupe. Recently, L. fulica infestations were detected on Saint Lucia and Barbados. In 1966, a Miami, FL, boy smuggled three giant African snails into south Florida upon returning from a trip to Hawaii. His grandmother eventually released the snails into her garden. Seven years later, more than 18,000 snails had been found along with scores of eggs. The Florida State eradication program ...
Achatina fulica is hermaphroditic; each individual snail has both male and female reproductive parts. There are no distinguishing parts separating sexes because each snail contains both sex reproductive systems. They do not self-fertilize, so the snails need to mate with another snail of their species. As a Stylommatophiora, Achatina fulica does not mate randomly; the snails mate with respect to age and size of other snails. Immature, small snails that are still growing produce only spermatozoa, while larger, mature adults produce both spermatozoa and ova. There is an age dependent mate choice when it comes to young snails because they need and prefer older adults to mate with. Young giant African snails copulate at all hours of the night, while older adults mate in the middle of the night. The snails choose their mates with respect to size and age, but the reproductive stage-dependent mate is a more attractive mate than the body size-dependent mate choice. Mating occurs when one snail ...
Impact. Giant African snails are already present in several Caribbean countries. In terms of environmental impact, the snails feed on indigenous vegetation and pose a conservation problem by altering habitat and out-competing other snails for food. For agriculture, they have become a destructive pest of crops and garden plants. To humans, they are vectors for disease, such as, eosinophilic meningitis, caused by the parasite rat lungworm that is passed to humans through eating raw or improperly cooked snails.. Control. Hand-collecting followed by proper disposal remains the safest means of control. Some programs advocate the use of snail traps, using beer as bait. Others have incorporated poisoning with molluscicides and other chemicals, and even using flame-throwers to burn snails alive, but there are safety concerns associated with these methods. Biological control backfired when the rosy wolf snail Euglandina rosea introduced to more than 20 oceanic islands and a number of Asian countries as a ...

1. Achatina fulica - The East African land snail, or giant African land snail, scientific name Achatina fulica, is a species of large, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae. It is the smallest in size among all the desirable species for rearing in Africa.. Achatina fulica has a narrow, conical shell, which is twice as long as it is wide and contains 7 to 9 whorls when fully grown. The shell is generally reddish-brown in colour with weak yellowish vertical markings but colouration varies with environmental conditions and diet. A light coffee colour is common. Adults of the species may exceed 20cm in shell length but generally average about 5 to 10cm. The average weight of the snail is approximately 32 grams (Cooling 2005).. 2.

THE genetics of sex-ratio variation are important in considering the adaptive sex ratios of organisms since they are direct products of sex-ratio evolution (Bull 1983; Werren and Beukeboom 1998) as well as possible constraints (West and Sheldon 2002). An important distinction among the genetic factors producing sex-ratio variation is whether they are cytoplasmic sex factors, nuclear sex-ratio genes, or nuclear sex-determining genes (Werren and Beukeboom 1998). Cytoplasmic sex factors are expressed either in the parent or in the zygote and are usually inherited only through the female lineage; this is demonstrated by the bacterium Wolbachia (Stouthamer et al. 2002). Sex-ratio genes are those expressed in the parent that affect offspring sex ratios, such as X chromosome drive genes in Drosophila spp. (Stouthamer et al. 2002). Sex-determining genes are those expressed in the zygote that determine the zygotes sex.. These genetic factors all affect the brood sex ratios, but they differ in their ...

A case of mistaken identity sparked a false alarm this week when word spread that the giant African snail - a voracious mollusk that poses a potential health threat to humans - had come to town. [...] it is fantastic people are alerting local and state officials when they see something suspicious, she said. The giant African snail is considered one of the most destructive snails and a serious threat to crops. The African snail has been a problem in Florida, where the state agriculture department has collected more than 100,000 in the past two years. Two other large but harmless snails in Houston-area gardens may be mistaken for the more dangerous giant African: the island apple snail and the channeled apple snail, said Autumn Smith-Herron of the Institute for the Study of Invasive Species at Sam Houston State University.

ANNAPOLIS, MD (September 17, 2004) - Giant African Snails (GAS), which are illegal in the United States, are appearing in schoolrooms, pet stores and flea markets across the country (really!). While the snails can present some public health concerns, the agricultural and ecological damage they may cause, based on observations made in other parts of the world, is the most pressing issue. To increase public awareness of this problem, the Maryland Invasive Species Council has selected them as Invaders of the Month for September. GAS is an amusing acronym for yet another potentially serious threat to American agriculture, ecosystems and human health.

Wetland Restoration and Invasive Species: Apple snail (Pomacea insularum) Feeding on Native and Invasive Aquatic Plants Lyubov E. Burlakova,1,2 Alexander Y. Karatayev,l Dianna K. Padilla,3 Leah D. Cartwright,4,5
Snail mucin is pretty much exactly what it sounds like: it is a slimy secretion that comes from everyones favorite garden critter, snails.. According to popular K-beauty blog The Klog, snail mucin is harvested from species of edible snails like the Roman snail (the kind most often used in escargot), the garden snail, and the giant African snail. By only using snail mucin harvested from edible snails, beauty brands can ensure that the snail mucin used in their products are safe for topical application.. The snails are grown in captivity for sanitary and sustainability purposes, and snail farmers from Chile to Italy have developed ways to extract the magic goo without harming the snails. As featured in a short documentary by Great Big Story, Italian scientist and snail farmer Simone Sampo created a machine that he calls a spa for snails that helps the snails produce batches of mucin before they are re-released into Sampos garden.. It is worth noting that the snail mucin used in beauty products ...
The American state of Georgia faces a new problem as wildlife officials discovered the South American channeled apple snail along the Alabaha River in Pierce County last month. Similar snails have been seen in four American states, including at least nine Florida counties, and Indonesia.. Apple snails (those of the ampullariidae family) are tropical and sub-tropical freshwater snails. They are named for their round shell, which is apple shaped. The channeled apple snail (Pomacea canaliculata) has a yellow-to-brown shell that may grow to the size of a baseball. Unlike many other freshwater gastropods, Apple Snails have both a lung and a gill. This allows them to live even in oxygen-poor waters. Outside of their natural habitat of South America, the snails have no natural enemies. As they reproduce quickly and feed on aquatic plants, which provide food and shelter for native species, they can be devastating to their new environment.. This discovery is one of particular interest because of the ...
By setting up a freshwater tank, feeding your snails, and giving them plenty of calcium, you can happily take care of some apple snails. Apple snails inhabit various ecosystems: ponds, swamps and rivers. Native to South America, apple snails were introduced to Taiwan in the 1980s as a potential food source. It may also provide clues as to why apple snails are able to colonise new habitats so successfully, and raises inevitable questions regarding the role of the aquarium trade in facilitating some of these introductions.

Amazonian giant snail. This large gastropod mollusc is from the Megalobulimus genus, which consists of species found in South America. Adult Megalobulimus snails can reach lengths of around 8 centimetres. Like most land snails, this one breathes air, and has a shell constructed from calcium carbonate. At left are the snails eye stalks (ommatophores). Snails are invertebrates, crawling over surfaces that they lubricate by secreting mucus. The mucus also prevents them from drying out. Snails are generally herbivorous. Photographed in Ecuador. - Stock Image C011/9610
HOUSTON - It wasnt snakes on a plane but rather snails on a plane.. ,, Read more trending news. Customs and Border Protection said that they stopped a woman who was traveling from Nigeria to the U.S.. They said they found 15 live giant land snails inside her carry-on bag,. The discovery was made earlier this month at the George Bush Intercontinental Airport.. The woman had claimed dried beef on her form but eventually amended it to include the snails.. The gastropods were found during a search of the womans luggage in three zip-closed bags with fresh leaves and a quarter-pound of beef, officials said.. The snails, which are also called Banana Rasp Snails, are invasive and could impact agriculture, natural ecosystems, human health or commerce, officials said..

Biological Notes. Steps . Under the Biosecurity Act 2015, golden apple snail is classified as prohibited matter.The Rice Biosecurity Zone has been established for the long term management of various pests and diseases, including golden apple snail. The golden apple snail (GAS) was introduced in the Philippines between 1982 and 1984 to supplement sources of food protein of low-income Filipino farmers. into the environment has led to the infestation of water bodies including ponds and rice fields in many Southeast Asian countries. If anyone has any clue any help would be appreciated. Due to serious effects of GAS in rice cultivation, farmers have resorted to use synthetic molluscicides for controlling damages caused by GAS leading to negative impact toward the environment and human health.

We hypothesized that apple snails would change life-history traits in the presence of common carp to reduce or avoid predation risk. Carp of about 150 mm body length were released in small plots set in a rice field in southern Japan at 0, 0.2, or 0.6 carp/m2. Egg-mass size, proportion of hatched eggs, and duration of hatching of the snail were measured once or twice a week from July to September. Snails collected in traps were used to estimate both snail density by the Jolly-Seber mark-recapture method and distribution of shell lengths in each plot. The weight of the snail was regressed on a size-weight equation, and the snail biomass was determined by multiplying the estimated density and the regressed weight. The reproductive effort of the snails was calculated as the number of eggs divided by the biomass of adult females. The egg mass size and reproductive effort were significantly increased in the presence of carp. These increases were considered as life-history changes of apple snails in the
Image-based cell profiling has become a common tool to identify phenotypic changes in cells exposed to various stimuli. To apply this approach to any research organism, we developed Image3C (Image-Cytometry Cell Classification), a tool that enables clustering of single cells based on their intrinsic phenotypic features by combining image-based flow cytometry with cell cluster analysis. We conducted a morphology analysis of hematopoietic tissue from zebrafish and a phagocytosis experiment. Here, Image3C could identify major hematopoietic cell lineages and, in addition, cells with specific functions, which abundance can be statistically compared between different treatments. To test the versatility of Image3C, we also clustered hemocytes of the apple snail Pomacea canaliculata obtaining results consistent with those collected by classical histochemical approaches. These experiments illustrate how Image3C can be used to classify and visualize heterogenous cell population obtained from either ...
An account is given of a laboratory investigation designed to evaluate the extent to which the freshwater pulmonate snail Biomphalaria glabrata (Say) can utilize various species of aquatic plants, mainly macrophytes, when presented in the following forms over different time scales: (i) normal plants; (ii) dried plant material; (iii) homogenized plant material in calcium alginate matrices; (iv) water-soluble filtrates of plant homogenates in the medium. The following propositions, derived from the theory of phased coevolution of components of the module consisting of the epiphytic bacteria, algae, snails and macrophytes, are evaluated on the basis of the present results and others including those obtained in this laboratory, (i) That as the snails had become specialized to exploit surface communities of epiphytic algae, decaying plant material and dissolved organic matter (DOM) early in their evolutionary history they would continue to exploit these resources when they later become associated ...

If you are reticent about trying snails, do not order a whole portion, snails are sold in dozens, and you may order just half-a-dozen in most restaurants. Ask. Consider dipping your little toe in first, just to test the water, and for that, you do not even have to eat a snail. Just like when you first ordered mussels order a small portion. In France when you order your first half portion of snails, order a demi-douzaine descargot, the smallest portion sold, of Escargots à la Bourguignonne, snails prepared in the manner of Burgundy. Your order will bring you half a dozen snails cooked in the style of Burgundy; Frances most famous recipe snail recipe.

Effects of Breed on Reproductive Efficiency of Two Most Popular Snails [Archachatina marginata (S) and Achatina achatina (L)] in Nigeria
There may be more than 50,000 species of snails in the world, and each of these species are of three basic types, land snails, sea snails, and freshwater snails.Some types of snails include the Roman snail, the garden snail, and the giant African land snail. There are thousands of species of snails.
A snail is a common name for a kind of mollusc. The term is used for a gastropod with a coiled shell. Their fossil records extends back into the Carboniferous period.[1] Land snails and slugs breathe with a kind of lung. They used to be put together in a group, the Pulmonata. This was a well-known order in traditional taxonomy. However, the Pulmonata is polyphyletic.[2] This means the same life-style evolved in a number of different lines. This is called convergent evolution. Therefore, the Pulmonata is no longer an official term in biological classification. The term snail is also sometimes used for aquatic snail-like gastropods, which usually have gills. Actually, most snail species are marine snails. There are more species of them, and they are far greater in numbers. Many kinds of snails can also be found in fresh water habitats. Most land snails and slugs are herbivorous. Aquatic snails and slugs are usually omnivores or predatory carnivores. In many countries around the world, people eat ...
Heat stress sufficient to cause cellular damage triggers the heat-shock response, the enhanced expression of a group of molecular chaperones called heat-shock proteins (hsps). We compared the heat-shock responses of four species of marine snails of the genus Tegula that occupy thermal niches differing in absolute temperature and range of temperature. We examined the effects of short-term heat stress and thermal acclimation on the synthesis of hsps of size classes 90, 77, 70 and 38 kDa by measuring incorporation of (35)S-labeled methionine and cysteine into newly synthesized proteins in gill tissue. Temperatures at which enhanced synthesis of hsps first occurred (T(on)), temperatures of maximal induction of hsp synthesis (T(peak)) and temperatures at which hsp synthesis was heat-inactivated (T(off)) were lowest in two low-intertidal to subtidal species from the temperate zone, T. brunnea and T. montereyi, intermediate in a mid- to low-intertidal species of the temperate zone, T. funebralis, and ...

Tiny marine snails known as sea butterflies appear to fly underwater much like winged insects do when taking to the sky - representsing a remarkable example of convergent evolution, where two unrelated species develop features that are used in similar ways.
By DAVID MERCER. Associated Press Writer. CHAMPAIGN, Ill. (AP) Scientists worry that a rapidly reproducing, tiny invasive snail recently found in Lake Michigan could hurt the lake s ecosystem.. The New Zealand mud snail joins a long and growing list of nonnative species moving into the Great Lakes, threatening to disrupt the food chain and change the local environment.. Scientists checking Lake Michigan water samples earlier this summer found a population of the New Zealand mud snail, the Illinois Natural History Survey said. They grow to only a few millimeters several dozen could sit on the surface of a dime making them hard to spot.. The snails reproduce asexually and in large numbers, and have no natural predators in North America, Kevin Cummings, a scientist who works for the Natural History Survey, said Thursday.. That means they could quickly spread, at high enough densities to out-compete native invertebrates for food and living space, he and other scientists say.. It s hard enough to ...

Like all the other mollusks, snails are one nauseating creatures that can make your life completely miserable. Usually snails dwell on the aquatic environments especially the snail that lives nearby water and those snails are not as bad for the human kind as the garden snails. Garden snails are found in chunks at your gardens, orchards and porches. Snails are also called as slugs but there is a slight difference between snails and slugs and that is that the slugs have got no shells on their surfaces and on the other hand the garden snails have got shells on their surfaces. The main problem with the snails is that the breed in great number and it is quite difficult to control their reproduction, when they start reproducing they go on and on in a single month. They only need a month to reproduce as much as they can.. ...
During the nineteenth century the mud snail Ilyanassa obsoleta was abundant on sand and mud flats, wood works, sea walls, salt marshes, eel grass beds, and cobble beaches in New England. With the exception of sand and mud flats, these habitats are now largely occupied by the introduced periwinkle, Littorina littorea. To determine whether Littorina competitively displaces Ilyanassa, an experimental study was conducted at a site in Barnstable Harbor, Massachusetts where the observed distributions overlapped by 3% by Morisitas index. Mark-recapture studies suggested that the distribution of Littorina was limited by an abiotic factor, currents, through which this species realized its fundamental niche. In contrast, density manipulations demonstrated that Ilyanassa emigrated from areas where Littorina exceeded densities of 2 to 5 per 0.25 m2. Littorina limited the upper and lower distribution of Ilyanassa and affected its microhabitat distribution in the mid intertidal zone. Habitat displacement was 70% for
We have developed and validated a qPCR assay and water filtration procedure for detecting the presence of environmental DNA shed by the invasive and widespread aquatic nuisance species New Zealand Mud Snail (NZMS), Potamopyrgus antipodarum. Our qPCR assay targets the junction of two P. antipodarum mitochondrial genes, rather than using primers in a single, highly conserved mitochondrial gene such as Cytochrome Oxidase I (CO1), as a way of decreasing the likelihood of getting false PCR positives due to cross-reactivity in taxonomically complex filtered water samples. Additionally, our qPCR assay uses a serial dilution series of plasmid DNA containing the NZMS target primer and probe sequences as a positive control and to generate the standard curve. This allows an absolute quantitation of the efficiency and sensitivity of the qPCR assay and the number of NZMS target DNA molecules in a sample; the demonstrated sensitivity is less than 10 molecules per reaction. The specificity of the assay for ...

  • What Does Snail Slime Actually Do for Your Skin? (
  • In recent years, snails have gone from garden dweller and French appetizer to practically ubiquitous skin-care ingredient: Their mucin (the slime they trail in their wake) forms the foundation for a recent wave of hyperpopular creams, masks, and serums - many of which we've tried and loved here at the Strategist. (
  • If you've ever tried snail-slime products and noticed your skin looking extra supple and glowy, you're not imagining it. (

  • If you've been controlling snails on your own property, but your neighbors haven't, the odds are very high that you'll now have an infestation. (
  • Look in your garden at night, when snails and slugs are active, and determine the severity of the infestation. (
  • If you want to protect young bedding plants from decollete snails, use snail bait or try a physical barrier such as a line of crushed eggshells, sharp sand or wood ashes. (
  • Please note that some snail bait is toxic to cats, dogs and lizards. (
  • Cavashema agreed and added: 'The use of snail bait is a therapy, not a cure. (
  • If the population is exploding and there seem to be snails everywhere, you may want to use snail bait to reduce the numbers until they can be controlled by nontoxic methods. (

  • The Chinese Mystery Snail has been introduced to America by Via buckets. (
  • The most amazing thing about the Chinese Mystery Snail is that they can be gold, black, and blue. (
