Inventories should produce comparable information, both between administrative units, as well as across time. They will generate the baseline information that will be used to support a variety of management activities, including, but not limited to; watershed analysis, timber sales, range allotments, special use permitting, and fish habitat and watershed restoration programs. They will also serve as the basis for stream monitoring and evaluation programs. Specifically, inventories will identify existing aquatic and riparian conditions, identify factors limiting the productive capabilities of habitats, measure attainment of meeting stream habitat objectives, and help to assess cumulative watershed effects. The inventories can be used to monitor and refine Land Management Plan Standards and Guidelines. The Pacific Northwest Region (Region 6) stream inventory is designed on a hierarchical scale to provide the user the opportunity to choose an inventory protocol which meets the data needs for the questions asked. Level I is the basic in-office procedure which identifies standard attributes of the watershed/stream to be analyzed. Its primary objective is to document and consolidate sources of general knowledge

  • Learning in the Land Snail (Helix Aspers a Mliller)*
    Bulletin of the Psychonomic Society 1974, Vol. 4 (SA), 476-478 Learning in the land snail (Helix aspers a Mliller)* R. K. SIEGEL and M. E. JARVIK Departments of Pharmacology and Psychiatry, University of California, Los Angeles Los Angeles, California 90024 A group of two experiments are discussed which demonstrate avoidance learning in land snails. Experiment I utilized the snail's negative geotaxis and its chemoreceptive characteristics and required the snail to climb a vertical pole which contained a quinine-saturated loop of thread at the top. Experiment II substituted electric shock loops for the quinine. Snails in both experimental groups manifested progressively increasing climbing latencies and avoidance responses throughout five successive training sessions and a one week retention test. Control animals which received noncontingent quinine or shock did not show evidence of learning. These results provide evidence of rapid avoidance learning in gastropod mollusks. Very few investigators have examined the problem of employed a pole-climbing response with quinine as an learning in snails (see reviews by Stephens & McGaugh, aversive stimulus at the top of the pole. These authors 1972; Willows, 1973). Early workers have suggested that demonstrated both short- and long-term memory of the these gastropods show evidence of classical conditioning aversive experience as well as habituation of the climbing (Thompson, 1917), maze learning (Garth & Mitchell, response itself with a neutral water stimulus. This 1926; Fischel, 1931), and habituation (Humphrey, learning appeared to be modifiable by length of 1930; Grindley, 1937). The phenomenon of classical laboratory housing, humidity, nutrition, and conditioning in snails has been recently reexamined by reproductive conditions.

  • Photoperiod and Temperature Interaction in the Helix Pomatia
    Photoperiod and temperature interaction in the determination of reproduction of the edible snail, Helix pomatia Annette Gomot Laboratoire de Zoologie et Embryologie, UA CNRS 687, Faculté des Sciences et Techniques et Centre Universitaire d'Héliciculture, Université de Franche-Comté, 25030 Besançon Cedex, France Summary. Snails were kept in self-cleaning housing chambers in an artificially con- trolled environment. Mating was frequent under long days (18 h light) and rare under short days (8 h light) regardless of whether the snails were kept at 15\s=deg\Cor 20\s=deg\C.An interaction between photoperiod and temperature was observed for egg laying. The number of eggs laid (45\p=n-\50/snail)and the frequency of egg laying (90\p=n-\130%)were greater in long than in short days (16\p=n-\35/snailand 27\p=n-\77%)but a temperature of 20\s=deg\C redressed, to some extent, the inhibitory effect of short days. At both temperatures only long photoperiods brought about cyclic reproduction over a period of 16 weeks, con- firming the synchronizing role of photoperiod on the neuroendocrine control of egg laying in this species of snail. Keywords: edible snail; mating; egg laying; photoperiod; temperature Introduction The effects of photoperiod and temperature, which influence most reproductive cycles of animals of temperate regions, have given rise to a certain number of observations for pulmonate gastropods. In basommatophorans, the influence of photoperiod and temperature on reproduction has been shown in four species of lymnaeids and planorbids (Imhof, 1973), in Melampus (Price, 1979), in Lymnaea stagnalis (Bohlken & Joosse, 1982; Dogterom et ai, 1984; Joosse, 1984) and in Bulinus truncatus (Bayomy & Joosse, 1987).

  • Stimulation of Genital Eversion in the Land Snail Helix Aspersa by Extracts of the Glands of the Dart Apparatus DANIEL J.D
    THE JOURNAL OF EXPERIMENTAL ZOOLOGY 238:129-139 (1986) Stimulation of Genital Eversion in the Land Snail Helix aspersa by Extracts of the Glands of the Dart Apparatus DANIEL J.D. CHUNG Division of Biological Sciences, and Museum of Zoology, University of Michigan, Ann Arbor, MI 48109 ABSTRACT The dart apparatus, used during courtship in some groups of hermaphroditic land snails, has long been assumed to have a “stimulatory” effect on the mating partner, though how stimulation occurs and exactly what function it serves has never been determined. In this study, extracts of the mucous glands of the dart apparatus of the land snail Helix aspersa were injected into conspecifics and into a related snail, Cepaea nemoralis, in order to test the hypothesis that the dart is used to achieve inflow of bioactive mucous gland secretions into the darted snail. Helix aspersa injected with the extract responded by everting their terminal genitals; eversion normally takes place during courtship and mating. Boiling the extract increased the bioactiv- ity. Pronase-treated extract lost bioactivity, and gel filtration of the boiled extract indicated that the active substance has a molecular weight of about 5,000. The active substance may be a polypeptide. Cepaea nemoralis also everted their genitals when injected with the boiled Helix extract. The active substance appears to be a contact sex pheromone, the second such pheromone in a pulmonate land snail for which experimental evidence has been obtained. Accessory organs in the terminal genitalia dart might cause increased tonus of the pen- of the hermaphroditic land snail order Sty- ial muscles.

Simple Summary: The superfamily Helicoidea is a large and diverse group of Eupulmonata. The su- perfamily has been the subject of several molecular and phylogenetic studies which greatly improved our knowledge on the evolutionary relationships and historical biogeography of many families. In contrast, the available karyological information on Helicoidea still results in an obscure general picture, lacking a homogeneous methodological approach and a consistent taxonomic record. Never- theless, the available karyological information highlights the occurrence of a significant chromosomal diversity in the superfamily in terms of chromosome number (varying from 2n = 40 to 2n = 62), Citation: Petraccioli, A.; Crovato, P.; chromosome morphology and the distribution of different karyological features among different Guarino, F.M.; Mezzasalma, M.; taxonomic groups.

Vikhrev1,2 The radicine pond snails represent a species-rich and widely distributed group, many species of which are key vectors of human and animal trematodoses. Here we clarify the taxonomy, distribution and evolutionary biogeography of the radicine lymnaeids in the Old World based on the most comprehensive multi-locus molecular dataset sampled to date. We show that the subfamily Amphipepleinae is monophyletic and contains at least ten genus-level clades: Radix Montfort, 1810, Ampullaceana Servain, 1881, Peregriana Servain, 1881, Tibetoradix Bolotov, Vinarski & Aksenova gen. nov., Kamtschaticana Kruglov & Starobogatov, 1984, Orientogalba Kruglov & Starobogatov, 1985, Cerasina Kobelt, 1881, Myxas G. B. Sowerby I, 1822, Bullastra Bergh, 1901, and Austropeplea Cotton, 1942. With respect to our phylogeny, species-delimitation model and morphological data, the Old World fauna includes 35 biological species of radicines. Tibet and Eastern Europe harbor the richest faunas, while East Asia and Africa appear to be the most species-poor areas. The radicine clade could have originated near the Cretaceous – Paleocene boundary. The Miocene great lakes in Eurasia seems to be the most important evolutionary hotspots shaping spatial patterns of recent species richness.

  • Brown Garden Snail European Brown Snail
    Colorado Mollusk of Interest Brown Garden Snail European Brown Snail Scientific Name: Cornu aspersum (Muller) (= Helix aspersa; = Cyptomphalus aspersa; = Centareus aspersum) Phylum: Mollusca Class: Gastropoda Figure 1. Brown garden snail. Order: Pulmonata Family: Helicidae Identification and Descriptive Features: The brown garden snail is the largest snail one may find in Colorado. It has a globular, whorled shell that may be 28-32 mm in diameter (1 - 1 1/4- in) in full-grown adults. The shell is finely wrinkled and yellow or horn colored with darker brown banding. The opening of the shell is oval or crescent shaped and has the lip turned up. Immature snails resemble the adults but are smaller. Distribution in Colorado: The brown garden snail is native to Britain, western Europe and regions that surround the Mediterranean and Black Seas. It has been distributed widely worldwide, intentionally (as an escargot species) and accidentally. It has been repeatedly introduced accidentally into Colorado, most frequently on nursery stock. Establishment appears to have occurred in some locations in Boulder and Jefferson counties; it is likely present in many other areas of the state. Dry conditions and extreme Figure 2. Brown garden snail. Photograph winter cold will determine the ultimate distribution courtesy of Bob Hammon. of this species within the state. Life History and Habits: The brown garden snail is normally active at night, although may be observed feeding during wet, overcast periods. Eggs are laid in moist soil, deposited in a mass of several dozen in a cavity scooped 2-3 cm deep by the “foot” of the snail.

    { An E>l.amination of the concept of Arousal within the Context of the Sexual Behaviour of the snail, Helix aspersa Shelley A. Adamo Department of Biology McGill university, Montreal April, 1990 A thesis submitted te the Faculty of Graduate Studies and Research of McGill University in partial fulfillment of the requirements for the degree of Ph.D. @shelley Adamo, 1.990 .------------------------- ._--_. 2 ( Ta my parents, with love and gratitude for aIl their support and encouragement 3 Abstract Sexual 'arousal' in Helix aspersa can be divided into 2 components, sexual proclivity (the tendency of a snail to respond to conspecific contact with courtship) and sexual arousal (the intensity with which the snail courts) . Sexual proclivity and sexual arousal have different effects on feeding and locomotion and are differentially affected by sexual isolation, daily conspecific contact, and by a courtship pheromone found in the digitiform gland mucus. Therefore sexual arousal and sexual proclivity ara probably mediated by 2 separate ph}rsiological mechanisms. Behavioural state, or the animal' s general level of activity, correlates positively with mating behaviour. However, al though a central system controlling behavioural state probably exists, it has no direct effect on either sexual proclivity or sexual arousal. Confusion over the term 'arousal', which impedes neuroethological research in this area, would be decreased by the adoption of the terms used in this thesis. 4 Résumé "L'éveil" sexuel chez Hf'lix aspersa peut être divisé en deux composantes: la disposition sexuelle (soit la tendance d'un escargot à faire la cour lors d'un contact avec un congénère), et la stimulation ou l'éveil seyuel proprement dit (c'est-à-dire l'intensité avec laquelle l'escargot fait la cour).

    Bargues et al. Parasites & Vectors 2011, 4:132 http://www.parasitesandvectors.com/content/4/1/132 RESEARCH Open Access DNA sequence characterisation and phylogeography of Lymnaea cousini and related species, vectors of fascioliasis in northern Andean countries, with description of L. meridensis n. sp. (Gastropoda: Lymnaeidae) M Dolores Bargues, Patricio Artigas, Messaoud Khoubbane and Santiago Mas-Coma* Abstract Background: Livestock fascioliasis is a problem throughout Ecuador, Colombia and Venezuela, mainly in Andean areas where the disease also appears to affect humans. Transmission patterns and epidemiological scenarios of liver fluke infection have shown to differ according to the lymnaeid vector snail species involved. These Andean countries present the vectors Lymnaea cousini, L. bogotensis and L. ubaquensis, unknown in the rest of Latin America. An exhaustive combined haplotype study of these species is performed by means of DNA sequencing of the nuclear ribosomal 18S RNA gene, ITS-2 and ITS-1, and mitochondrial DNA cox1 gene. Results: The conserved 5.8S rDNA sequence corroborated that no pseudogenes are involved in the numerous non-microsatellite/minisatellite-related indels appearing between the ITS-2 and ITS-1 sequences when comparing different L. cousini - L. bogotensis populations. Sequence analyses and phylogenetic reconstruction methods including other lymnaeid vector species show that (i) L. bogotensis is a synonym of L. cousini, (ii) L. ubaquensis is a synonym of Pseudosuccinea columella, and (iii) populations of L. cousini hitherto known from Venezuelan highlands indeed belong to a new species for which the name L. meridensis n. sp. is proposed. This new species is described and a complete phenotypic differentiation provided.
