Müller, 1774) in Bulgaria (Gastropoda: Thiaridae) VIKTOR GASHTAROV1 & DILIAN GEORGIEV2 1P.O. Box 1733, 1000 Sofia, Bulgaria., E-mail: [email protected] 2Department of Ecology and Environmental Conservation, University of Plovdiv, Tzar Assen Str. 24, BG-4000 Plovdiv, Bulgaria. E-mail: [email protected] Received 8 January 2016 │ Accepted 17 January 2016 │ Published online 18 January 2016. The freshwater tropical snail Melanoides tuberculata (O. F. Müller, 1774) or red-rimmed melania is native to northern Africa and southern Asia, but it has been accidentally introduced in many other tropical and subtropical areas worldwide. M. tuberculata is both parthenogenic and ovoviparous so this makes it well adapted for invasion of new habitats (Appleton et al. 2009). It is often kept in aquaria and has also been accidentally introduced to thermal springs in colder parts of the world in the temperate zone (Glöer 2015). Figure 1. The collection locality of Melanoides tuberculata – the thermal stream near Pancherevo Dam Ecol. Mont., 5, 2016, 26-27 26 GASHTAROV & GEORGIEV M. tuberculata was never recorded in Bulgarian hot springs areas but was found in neighboring Serbia (Milenković & Gligorijević 2012). Our short note reports the first record of this species in a thermal spring in Bulgaria. On September 2015 the first author found a large amount of shells of M tuberculata at a thermal stream near Pancherevo Dam, close to the south part of Sofia city, N42.605297 E23.403451, 589 m alt. (Fig. 1, 2). On January 2016 he managed to collect and some living snails from the bottom of the same stream. Even this species could not spread in cold waters and its populations in temperate zones are restricted only at the areas of the hot springs, this could affect negatively the endemic hydrobiid snails if occur there. So introduction of the red-rimmed melania has to be avoided especially in such areas. Figure 2. Shells of Melanoides tuberculata found at the thermal stream near Pancherevo.

The amplified partial mt-COI Department of Biotechnology, gene sequence using universal primers, LCO1490 and HCO2198 resulted into ~700 base pair DNA Vignan’s University (VFSTRU), Vadlamudi, Andhra Pradesh, fragment. The obtained nucleotide sequence of partial COI gene of T. lineata was submitted to BLAST India analysis and 36 close relative sequences of the chosen genera, Cerithioidea were derived. Maximum likelihood (ML) algorithm in-biuilt in RAxML software tool was used to estimate phylogenetic their affinities. The present analysis revealed that a single assemblage of the family Thiaridae supported by a bootstrap value of 96% is earmarked at the base of the derived cladogram as a cluster and emerged as a sister group with another four Cerithioideans. Our dataset brought add-on value to the current taxonomy of Thiaridae of the clade Sorbeconcha by clustering them as sister and non-sister groups indicating the virtual relations. Out of seven genera, Tarebia and Melanoides formed as primary and secondary clusters within the Thiaridae. The monophyly of Thiaridae and its conspecifics were depicted in the cladogram.

Adams & A. Adams, 1854, are found in rivers, lakes, and other limnetic habitats. In Indonesia, Tarebia granifera (Lamarck, 1822) is the only species within the genus that has a wide distribution. The systematics and identity of this species are still doubtful due to high variation in shell morphology, especially shell height and ornamentation or sculpture of shell. To determine the identity of T. granifera from Lombok, Banten, and Maros, ontogenetic studies have been conducted. The results showed that T. granifera from Lombok produce the highest number of embryonic shells. The number of progeny in the brood pouch from a single individual of T. granifera can vary between 9 to 203 embryonic shells which are found in various stages of 0.22 mm to about 5 mm in size inside the brood pouch. Key words: embryonic shell, ontogeny, subhaemocoelic brood pouch, Tarebia granifera, Thiaridae INTRODUCTION Tarebia granifera (Lamarck, 1822) (Thiaridae) occurs in freshwater bodies, in lotic as well as lentic habitats. This species belongs to benthic fauna and lives attached to different kinds of substrate or on the banks of aquatic habitats.

It was determined that molluscs have naturalized in the Zaporizhia Nuclear Power Plant cooling pond, quickly increased their number and created a threat to hydraulic structures. Taking into account biological features of Thiaridae mollusks and technical and ecological features of Zaporizhia NPP, we carried out a series of experiments using biological control measures (the use of predatory species of hydrobionts) and mechanical means for controlling mollusks. Representatives of different taxons of the Animalia Kingdom were selected as predatory species of hydrobionts, which potentially can consume gastropods: Mollusca, Crustaceans and Fish. It has been found experimentally that the use of marbled crayfish Procambarus virginalis (Lyko, 2017), pumpkinseed Lepomis gibbosus (Linnaeus, 1758) and Botia lohachata Chaudhuri, 1912 has not given positive results in the development of measures to control the number of molluscs. Positive results were obtained in a series of experiments with predatory mollusc assassin snail Clea helena (von dem Busch, 1847), but it was noted that in the presence of more accessible feeds, assassin snail Clea helena (von dem Busch, 1847) consumes smaller quantities of Thiaridae mollusks.

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.

Taxonomy, Conservation, and the Future of Native Aquatic Snails in the Hawaiian Islands
diversity Perspective Taxonomy, Conservation, and the Future of Native Aquatic Snails in the Hawaiian Islands Carl C. Christensen 1,2, Kenneth A. Hayes 1,2,* and Norine W. Yeung 1,2 1 Bernice Pauahi Bishop Museum, Honolulu, HI 96817, USA; [email protected] (C.C.C.); [email protected] (N.W.Y.) 2 Pacific Biosciences Research Center, University of Hawaii, Honolulu, HI 96822, USA * Correspondence: [email protected] Abstract: Freshwater systems are among the most threatened habitats in the world and the biodi- versity inhabiting them is disappearing quickly. The Hawaiian Archipelago has a small but highly endemic and threatened group of freshwater snails, with eight species in three families (Neritidae, Lymnaeidae, and Cochliopidae). Anthropogenically mediated habitat modifications (i.e., changes in land and water use) and invasive species (e.g., Euglandina spp., non-native sciomyzids) are among the biggest threats to freshwater snails in Hawaii. Currently, only three species are protected either federally (U.S. Endangered Species Act; Erinna newcombi) or by Hawaii State legislation (Neritona granosa, and Neripteron vespertinum). Here, we review the taxonomic and conservation status of Hawaii’s freshwater snails and describe historical and contemporary impacts to their habitats. We conclude by recommending some basic actions that are needed immediately to conserve these species. Without a full understanding of these species’ identities, distributions, habitat requirements, and threats, many will not survive the next decade, and we will have irretrievably lost more of the unique Citation: Christensen, C.C.; Hayes, books from the evolutionary library of life on Earth.

Diego E. Gutiérrez Gregoric *, Verónica Núñez, Noelia S. Ferrando & Alejandra Rumi A BSTRACT In this work is reported the first record of Melanoides tuberculatus in the Iguazú River basin (Argentina-Brazil). This species is native to southern Asia and was anthropogenically introduced to America in the 1960s decade. Sixteen specimens (one adult and 15 juvenile) of M. tuberculatus were recorded at only one site, the rapids of Iguazú River at Isla San Martín, Iguazú National Park, Argentina, in June 2005. This finding of M. tuberculatus specimens suggests the presence of a stable population that would represent a threat to the native mollusk fauna, given that this species promotes replacement and impoverishment of mollusk diversity.
