From the Black Sea Coast to Poland - An Incredible Journey of Monacha cartusiana (O. F. Müller, 1774)
Katarzyna Kurek , Kamil Najberek
Folia Malacologica , 2009, DOI: 10.2478/v10125-009-0005-0
Abstract: Though Monacha cartusiana (O. F. Müll.) is known to expand its distribution range through accidental introductions, the migration routes are usually unknown. The story of an individual which covered a distance of about 1,500 km from the Crimea to Poland, attached to a car, is one of the few examples of a fully documented migration pathway.
Dvě nové lokality tmavoretky bělavé Monacha cartusiana (O.F. Müller, 1774) na Moravě Two new localities of Monacha cartusiana (O.F. Müller, 1774) in Moravia, Czech Republic

Abstract: Monacha cartusiana is one of the non-native molluscan species in the Czech Republic. It comes from the Mediterranean region, and during the 20th and 21th century it spreads on some localities nearly all over the Europe. Two new localities of Monacha cartusiana (O.F. Müller, 1774) were discovered in Moravia, Czech Republic. There were found several specimens in the Kamenná and the Kurovicky Lom Nature Monuments.
Nivní malakofauna povodí ú těckého potoka a její vyvoj během holocénu The floodplain mollusc fauna of the ú těcky Brook catchment basin and its development during the Holocene (North Bohemia, Czech Republic)

Abstract: This paper presents a research of floodplain mollusc assemblages of the ú těcky Brook catchment basin (Elbe tributary, North Bohemia, Czech Republic). Altogether, 71 mollusc species (69 species of Gastropoda, 2 species of Bivalvia) were recorded in the study sites between 2007 and 2011, representing 29% of the total Czech malacofauna. The common forest species dominated (41% of all recorded species) and included some rare woodland species as Daudebardia rufa, Discus perspectivus, Macrogastra ventricosa, and Sphyradium doliolum. Rare wetland species protected by the NATURA system Vertigo angustior and endangered wetland species Vallonia enniensis were also found. The richest assemblages occurred on the upper part of the brook, while the lower part was very species poor due to agriculture land use in this fertile floodplain. A small calcareous moorland, situated in the northeastern vicinity of ú těk Town (north Bohemia) includes a Holocene mollusc succession that was subdivided into three local mollusc zones: I – basal zone with marked numbers of Discus ruderatus, Vertigo geyeri and numerous aquatic taxa, II – with forest species including Platyla polita and III – dominated by open-ground and catholic species. Despite the specific conditions of the moorland habitat the succession largely corresponds with the standard developmental pattern of the mollusc fauna in the zone of mid-European uplands. Of particular interest is the developmental break reflected by the poor fauna in the layer 3. The malacofauna of the ú těcky Brook can be used as a model of alluvial mollusc assemblages of the brook floodplain that is situated in the warm area of Central Europe with long-term history of agriculture land use.
Ants as shell collectors: notes on land snail shells found around ant nests
Barna Páll-Gergely,Péter Sólymos
Malacologica Bohemoslovaca , 2009,
Abstract: We investigated the shell collecting activities of harvester ants (Messor spp.) in semi-arid grasslands and shrubs in Turkey. We found eleven species of snails in the area, two of them were not collected by ants. Eight – mainly small sized – snail species were found on ant nests in a habitat characterized by shrubs, three in rocky grassland and four in a grassland habitat. Some shells (e.g. Chondrus zebrula tantalus, Multidentula ovularis) might be taken into the nests, and we hypothesise that some of these snail species are consumed by ants (Monacha spp.). From a fauna inventory perspective, shell collecting activities of harvester ant may help malacologists to find snail species which are normally hidden for a specialist (e.g. Oxychilus hydatinus, Cecilioides spp.) due to their special habits.

Journal of Central European Agriculture , 2003,
Abstract: An extremely dangerous pest especially for the resinous species (spruce fir, pine tree, fir tree, larice, duglas) which can also attack leafy trees is Lymantria monacha. The larva of this pest attacks as of the beginning of spring. In the beginning they attack the barely open buds which they gnaw, then the needles are partially or totally eaten. The studies shows the situation of Lymantria monacha adults caucht with the aid of ATRALYMON sexual attractant in 2001 and 2002.
Molluscicidal Activity of Methomyl and Cardenolide Extracts from Calotropis procera and Adenium arabicum Against the Land Snail Monacha cantiana

Molecules , 2012, DOI: 10.3390/molecules17055310
Abstract: In this work, we have evaluated the molluscicidal activity of two cardenolide extracts from Adenium arabicum Balf f. [the benzene (B) and methanol (M) extracts], one cardenolide extract from Calotropis procera (Aiton) W.T. Aiton (extract C), and methomyl against the harmful land snail Monacha cantiana (Montagu). The contact LD50 values for the above mentioned plant extracts were 12.62, 34.63, and 34.35 mg·kg?1 of body weight, respectively, while the LD50 for methomyl was 116.62 mg·kg?1, that is, the plant extracts were 9.24, 3.37, and 3.4 times more toxic than methomyl. In addition, a simple colorimetric method, based on Kedde reagent, was modified to determine cardenolide concentrations in plant extracts. Thin layer chromatography analysis (TLC) showed several cardiac glycosidal compounds in each plant extract. The results proved that cardiac glycosides are promising candidate compounds that could be used to control land snails, or exploited to develop new, effective, and environmentally friendly molluscicides.
First occurrence of the Kentish Snail Monacha cantiana (Mollusca: Gastropoda: Hygromiidae) in the Czech Republic

Malacologica Bohemoslovaca , 2010,
Abstract: We document the first occurrence of the Kentish Snail Monacha cantiana (Montagu, 1803) from Prague, Czech Republic. During autumn 2009, an abundant population of M. cantiana was found at sites with suitable vegetation and microclimatic conditions, predominantly composed of grassy vegetation cover. It is expected that this species will continue to spread in the Czech Republic.

Abstract: a diversity of all-female fishes of the genus poeciliopsis coexists with their sexual ancestor species in streams of western mexico. all-females are hybrids that depend on the sperm of paternal species to reproduce. rare-female advantage is one of several hypotheses that attempt to explain how the diversity of all-female biotypes is maintained within the poeciliopsis reproductive complexes. according to this hypothesis, the uncommon all-female biotype has a mating advantage over the common ones and has been maintained by a dynamic equilibrium process. in the p. monacha reproductive complex at arroyo de los platanos the density of two all-female biotypes (p. 2monacha-lucida i and ii) varies across pools. the objective of this study was to analyse fecundity and mating success of females from this arroyo to test the hypothesis. female mating success was inversely correlated to their density, supporting this hypothesis.

Abstract: The characteristics of Hooded Cranes'(Grus monacha) feeding sites in the east tide flat of Chongming Island were studied.The corm of Scirpus mariqueter is the main foods of the Hooded Crane in wintering in Chongming Island.There are fairly significant difference (P<0.01) on the foraging degree of the Hooded Crane,and significant differences (P<0.05) on the food's depth and weight of the bird between the site at the edges of the tidal channel and that far away the tidal channel.There are fairly significance (P<0.001) differences on the foraging degree,food's depth,number and weight of the bird among three sample lines.The effect of tidewater causes no significant difference on the foraging degree among the inner,middle and outer zones of Bulrush vegetation,but the food's depth and weight have fairly significance differences (P<0.001) among those zones.The mean feeding depth of the Hooded Crane can be used as an index in prediction its foraging sites.The tidal scour causes foods buried in the different depth,which has a great influence on the Hooded Crane feeding in the eastern tide flat of Chongming Island.

Abstract: A diversity of all-female fishes of the genus Poeciliopsis coexists with their sexual ancestor species in streams of western Mexico. All-females are hybrids that depend on the sperm of paternal species to reproduce. Rare-female advantage is one of several hypotheses that attempt to explain how the diversity of all-female biotypes is maintained within the Poeciliopsis reproductive complexes. According to this hypothesis, the uncommon all-female biotype has a mating advantage over the common ones and has been maintained by a dynamic equilibrium process. In the P. monacha reproductive complex at Arroyo de los Platanos the density of two all-female biotypes (P. 2monacha-lucida I and II) varies across pools. The objective of this study was to analyse fecundity and mating success of females from this arroyo to test the hypothesis. Female mating success was inversely correlated to their density, supporting this hypothesis.
