Size Structure, Age, Mortality and Fecundity in Viviparus Viviparus (Linnaeus, 1758) (Gastropoda: Architaenioglossa: Viviparidae)
Vol. 15(3): 109–117 SIZE STRUCTURE, AGE, MORTALITY AND FECUNDITY IN VIVIPARUS VIVIPARUS (LINNAEUS, 1758) (GASTROPODA: ARCHITAENIOGLOSSA: VIVIPARIDAE) BEATA JAKUBIK, KRZYSZTOF LEWANDOWSKI Department of Ecology and Environmental Protection, University of Podlasie, B. Prusa 12, 08-110 Siedlce, Poland (e-mail: [email protected]) ABSTRACT: Field and laboratory experiments were aimed at establishing the relationship between growth rate, age, mortality and fecundity of Viviparus viviparus (L.). Fecundity was found to depend on the female’s size. The size (shell dimensions) did not affect the size of newborn snails; females of different size classes produced offspring of the same shell height (4.0 mm) and width (4.5 mm). In the first year of the experiment growth rate was higher in the field than in the laboratory. Sex could be recognised and developing embryos could be found in females in the middle of the second year of the experiment. Juvenile V. viviparus appeared in the lab- oratory when the females were 18 months old and had achieved size class III. Their shell increments were uni- formly distributed, without visible dark winter rings or rings of summer growth inhibition. Winter and sum- mer rings appeared in the second year in the field culture; the second winter ring appeared in the third year of field culture. In the field females at the end of their second year contained embryos; they produced off- spring in the spring of the third year. KEY WORDS: Viviparus viviparus, fecundity, size structure, age structure, growth rate, mortality INTRODUCTION Body size and growth rate are important for the 1994, JACKIEWICZ 2003) and the largest individuals at functioning of any organism; they affect the chances the end of their life show a smaller fecundity of survival and producing offspring, accumulation (VALECKA &JÜTTNER 2000). -
Snail Distributions in Lake Erie: the Influence of Anoxia in the Southern Central Basin Nearshore Zone1
230 E. M. SWINFORD Vol. 85 Copyright © 1985 Ohio Acad. Sci. OO3O-O95O/85/OOO5-O23O $2.00/0 SNAIL DISTRIBUTIONS IN LAKE ERIE: THE INFLUENCE OF ANOXIA IN THE SOUTHERN CENTRAL BASIN NEARSHORE ZONE1 KENNETH A. KRIEGER, Water Quality Laboratory, Heidelberg College, Tiffin, OH 44883 ABSTRACT. The distributions and abundances of gastropods collected in sediment grab samples in 1978 and 1979 in the southern nearshore zone of the central basin of Lake Erie were compared with earlier gastropod records from throughout the lake. Since the 1920s, 34 species in eight families have been reported for the lake proper. Sixteen species have been reported only once, 13 of them in three reports prior to 1950. All but three of the species collected by two or more authors prior to the mid-1950s have also been collected in the past decade. The most frequently reported species are Walvata trkarinata, Bithynia tentaculata, Elimia ( =Goniobasis) livescens, Physella "sp.", Amnkola limosa, Pleuroceraacuta and V. sincera. Only six of 19 studies reported species densities, and most did not record sample locations, depths or substrates. Thus, only a limited comparison of the gastropod fauna between studies was possible, with the exception of several well documented studies in the western basin up to the early 1960s. Of four introduced species in Lake Erie, only two were found in the present study, and these appear to have no influence on the present distributions of the native species. The absence of snails in the south- western part of the study area and at the mouths of the Cuyahoga and Black rivers appears to be the result of prolonged anoxia during one or more summers preceding the study. -

(2015): “Europe, from Scandinavia to Greece.” Status in the United States From Kipp et al. (2015): “The species is established in the drainages of Lake Ontario (Mills et al. 1993; Peckarsky et al. 1993), Lake Michigan (Mills et al. 1993), and Lake Erie (Krieger 1985; Mackie et al. 1980; Peckarsky et al. 1993), but not Lake Superior (Jokinen 1992). Occurrences in Lake Huron do not warrant classification as established.” “Great Lakes Region: Bithynia tentaculata was first recorded in Lake Michigan in 1871, but was probably introduced in 1870 (Mills et al. 1993). It spread to Lake Ontario by 1879, the Hudson River by 1892, and other tributaries and water bodies in the Finger Lakes region during the 20th century (Jokinen 1992; Mills et al. 1993). It was introduced to Lake Erie sometime before 1930 (Carr and Hiltunen 1965; Krieger 1985). This snail’s range now extends from Quebec and Wisconsin to Pennsylvania and New York (Jokinen 1992). It has been recorded from Lake Huron, but only a few individuals were found in benthic samples from Saginaw Bay in the 1980s and 1990s (Nalepa et al. 2002).” Means of Introductions in the United States From Kipp et al. (2015): “Bithynia tentaculata could have been introduced to the Great Lakes basin in packaging material for crockery, through solid ballast in timber ships arriving to Lake Michigan, or by deliberate release by amateur naturalists into the Erie Canal, Mohawk River and Schuyler’s Lake (Mills et al. -

Clark and Charles Lydeard University of Alabama, Tuscaloosa, Alabama 15-18 March 2004 Acknowledgments We must begin by acknowledging Dr. Jack Burch of the Museum of Zoology, University of Michigan. The vast majority of the information contained within this workbook is directly attributed to his extraordinary contributions in malacology spanning nearly a half century. His exceptional breadth of knowledge of mollusks has enabled him to synthesize and provide priceless volumes of not only freshwater, but terrestrial mollusks, as well. A feat few, if any malacologist could accomplish today. Dr. Burch is also very generous with his time and work.

Life Cycle of Valvata Piscinalis (O. F. Müller, 1774) (Gastropoda: Heterobranchia) in the Laboratory
Vol. 15(4): 145–174 LIFE CYCLE OF VALVATA PISCINALIS (O. F. MÜLLER, 1774) (GASTROPODA: HETEROBRANCHIA) IN THE LABORATORY STANIS£AW MYZYK S¹polno 14, 77-320 Przechlewo, Poland ABSTRACT: Laboratory and field observations in 1994–2004 made it possible to ascertain the following para- meters of life cycle of Valvata piscinalis (O. F. Müller, 1774). In favourable food conditions (filamentous diatoms) female maturity was attained in 42–85 days from hatching (mean 59 days) at the body whorl diameter of 3.45–4.65 mm (mean 4.10 mm) and the number of whorls 3.25–3.75 (mean 3.53). In slightly less favourable food conditions (periphyton) the maturity was attained later at a somewhat lower mean shell size. The num- ber of cocoons and eggs produced during lifetime by snails kept in pairs was 18–113 and 387–2,862, respec- tively; the number of eggs per cocoon ranged from 0 to 76. Among singly kept snails only half laid cocoons (maximum 7 cocoons/6 eggs during lifetime), and the eggs failed to develop. The mean life span of snails fed mainly with periphyton was ca. 1 year (maximum 641 days); it was distinctly shorter in snails fed with filamen- tous diatoms (usually 5–7 months, rarely more than 11 months). In very unfavourable food conditions (small quantities of periphyton) female maturity was attained only after 1–2 years and the life span was not much lon- ger: maximum 830 days. In natural conditions (lake Sosnowe near S¹polno) reproduction started in the sec- ond half of April and lasted till half of July; the cocoons contained 10–37 eggs. -

It includes 39 species from 170 species found in Latvia. The category 0 has no species, there is 1 species in the first category, 6 species in the second category, 25 species in the third category, and 7 species in the fourth category. Evaluation criteria similar to these in the previously published Red Books have been used. Information on 64 species included in the IUCN LC category is also collected. There is no need for special protection measures for these species; however, the dynamics of their populations should be monitored. Key words: Latvia, mollusc species, protection status. Introduction Red List categories The first Red Data Book of Latvia was published 33 years The definitions of the following categories are based on ago (Aigare et al.
