Species Fact Sheet with Juga Hemphilli Hemphilli
SPECIES FACT SHEET Scientific Name: Juga hemphilli hemphilli (Henderson 1935) Common Name: barren juga Phylum: Mollusca Class: Gastropoda Order: Neotaenioglossa Family: Semisulcospiridae Taxonomic Note: Past genetic analysis by Lee et al. (2006) based on incorrectly identified museum voucher specimens suggested reassignment of the related subspecies Juga hemphilli dallesensis (and therefore the Juga hemphilli conspecifics, including Juga hemphilli hemphilli) to the genus Elimia. However, Foighil et al. (2009) conducted an additional analysis and determined that Juga hemphilli is indeed most closely related to other western Juga and should not be reassigned to the genus Elimia. Turgeon et al. (1998) do not recognize any subspecies of Juga hemphilli. Conservation Status: Global Status: G2T1 (May 2009) National Status: United States (N1) (June 2000) State Statuses: Oregon (S1), Wahington (S1) (NatureServe 2015) IUCN Red List: NE – Not evaluated Technical Description: This subspecies was originally described as Goniobasis hemphilli hemphilli (Henderson 1935). Burch (1982; 1989) revised this subspecies to the genus Juga to reflect the distribution of taxa west of the Continental Divide. Adult: Juga is a genus of medium-sized, aquatic, gilled snails traditionally treated as part of the subfamily Semisulcospirinae within the Pleuroceridae family, although the Semisulcospirinae subfamily was recently elevated to family level based on morphological and molecular evidence (Strong and Köhler 2009). The Pleuroceridae and Semisulcospiridae families both differ from the Hydrobiidae family in that the males lack a verge (male copulatory organ). The genus Juga is distinct from related pleurocerid snails based on reproductive anatomy and egg mass characters (Taylor 1966), as well as features of the ovipositor pore, radula, midgut, kidney, and pallial gonoduct (Strong and Frest 2007). -

Systematics of the North and Central American Aquatic Snail Genus Tryonia (Rissooidea: Hydrobiidae)
Systematics of the North and Central American Aquatic Snail Genus Tryonia (Rissooidea: Hydrobiidae) ROBERT HERSF LER m SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 612 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -

Freshwater Snail Guide
A Beginner’s Guide to Freshwater Snails of Central Scotland Freshwater snails are a diverse and fascinating group of molluscs found in ponds, lochs, canals, rivers and watery ditches all across the globe. This guide is a simple introduction to some of the most commonly encountered and easily identifiable freshwater snail species in Central Scotland. How do I look for freshwater snails? 1) Choose your spot: anywhere with water – your garden pond, a nearby river, canal or loch – is likely to have snails. 2) Grab a pond net (buy online or make your own by attaching a sieve to the end of an old broom or mop), a white tray or tub and a hand-lens or magnifier. 3) Fill the tray with water from your chosen habitat. Sweep the net around in the water, making sure to get among any vegetation (don’t go too near the bottom or you’ll get a net full of mud), empty your net into the water-filled tray and identify what you have found! Snail shell features Spire Whorls Some snail species have a hard plate called an ‘operculum’ Height which they Mouth (Aperture) use to seal the mouth of the shell when they are inside Height Pointed shell Flat shell Width Width Pond Snails (Lymnaeidae) Variable in size. Mouth always on right-hand side, shells usually long and pointed. Great Pond Snail Common Pond Snail Lymnaea stagnalis Radix balthica Largest pond snail. Common in ponds Fairly rounded and ’fat’. Common in weedy lakes, canals and sometimes slow river still waters. pools. -
Pomacea Canaliculata) Behaviors in Different Water Temperature Gradients
water Article Comparison of Invasive Apple Snail (Pomacea canaliculata) Behaviors in Different Water Temperature Gradients Mi-Jung Bae 1, Eui-Jin Kim 1 and Young-Seuk Park 2,* 1 Nakdonggang National Institute of Biological Resources, Sangju 37242, Korea; [email protected] (M.-J.B.); [email protected] (E.-J.K.) 2 Department of Biology, Kyung Hee University, Dongdaemun, Seoul 02447, Korea * Correspondence: [email protected]; Tel.: +82-2-961-0946 Abstract: Pomacea canaliculata (known as invasive apple snail) is a freshwater snail native to South America that was introduced into many countries (including Asia and North America) as a food source or for organic farming systems. However, it has invaded freshwater ecosystems and become a serious agricultural pest in paddy fields. Water temperature is an important factor determining behavior and successful establishment in new areas. We examined the behavioral responses of P. canaliculata with water temperature changes from 25 ◦C to 30 ◦C, 20 ◦C, and 15 ◦C by quantifying changes in nine behaviors. At the acclimated temperature (25 ◦C), the mobility of P. canaliculata was low during the day, but high at night. Clinging behavior increased as the water temperature decreased from 25 ◦C to 20 ◦C or 15 ◦C. Conversely, ventilation and food consumption increased when the water temperature increased from 25 ◦C to 30 ◦C. A self-organizing map (an unsupervised artificial neural network) was used to classify the behavioral patterns into seven clusters at different water temperatures. These results suggest that the activity levels or certain behaviors of P. canaliculata vary with the water temperature conditions. -

It is distributed throughout the island and commonly associated with ornamental aquatic plants. Although the species has previously been considered by some to be native to Singapore, its origin is currently categorised as unknown. Morphological comparisons of freshly collected specimens and material in museum collections with type material, together with DNA barcoding, show that both Physastra sumatrana, and a recent gastropod record of Stenophysa spathidophallus, in Singapore are actually the same species—the globally-invasive Physa acuta. An unidentified physid snail was also collected from the Singapore aquarium trade. -

Seasonal Reproductive Anatomy and Sperm Storage in Pleurocerid Gastropods (Cerithioidea: Pleuroceridae) Nathan V
989 ARTICLE Seasonal reproductive anatomy and sperm storage in pleurocerid gastropods (Cerithioidea: Pleuroceridae) Nathan V. Whelan and Ellen E. Strong Abstract: Life histories, including anatomy and behavior, are a critically understudied component of gastropod biology, especially for imperiled freshwater species of Pleuroceridae. This aspect of their biology provides important insights into understanding how evolution has shaped optimal reproductive success and is critical for informing management and conser- vation strategies. One particularly understudied facet is seasonal variation in reproductive form and function. For example, some have hypothesized that females store sperm over winter or longer, but no study has explored seasonal variation in accessory reproductive anatomy. We examined the gross anatomy and fine structure of female accessory reproductive structures (pallial oviduct, ovipositor) of four species in two genera (round rocksnail, Leptoxis ampla (Anthony, 1855); smooth hornsnail, Pleurocera prasinata (Conrad, 1834); skirted hornsnail, Pleurocera pyrenella (Conrad, 1834); silty hornsnail, Pleurocera canaliculata (Say, 1821)). Histological analyses show that despite lacking a seminal receptacle, females of these species are capable of storing orientated sperm in their spermatophore bursa. Additionally, we found that they undergo conspicuous seasonal atrophy of the pallial oviduct outside the reproductive season, and there is no evidence that they overwinter sperm. The reallocation of resources primarily to somatic functions outside of the egg-laying season is likely an adaptation that increases survival chances during winter months. Key words: Pleuroceridae, Leptoxis, Pleurocera, freshwater gastropods, reproduction, sperm storage, anatomy. Résumé : Les cycles biologiques, y compris de l’anatomie et du comportement, constituent un élément gravement sous-étudié de la biologie des gastéropodes, particulièrement en ce qui concerne les espèces d’eau douce menacées de pleurocéridés. -
