(Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: the Genera Nodilittorina, Austrolittorina and Afrolittorina
© Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 75–122. ISSN 0067-1975 The Subfamily Littorininae (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: The Genera Nodilittorina, Austrolittorina and Afrolittorina DAVID G. REID* AND SUZANNE T. WILLIAMS Department of Zoology, The Natural History Museum, London SW7 5BD, United Kingdom [email protected] · [email protected] ABSTRACT. The littorinine gastropods of the temperate southern continents were formerly classified together with tropical species in the large genus Nodilittorina. Recently, molecular data have shown that they belong in three distinct genera, Austrolittorina, Afrolittorina and Nodilittorina, whereas the tropical species are members of a fourth genus, Echinolittorina. Austrolittorina contains 5 species: A. unifasciata in Australia, A. antipodum and A. cincta in New Zealand, and A. fernandezensis and A. araucana in western South America. Afrolittorina contains 4 species: A. africana and A. knysnaensis in southern Africa, and A. praetermissa and A. acutispira in Australia. Nodilittorina is monotypic, containing only the Australian N. pyramidalis. This paper presents the first detailed morphological descriptions of the African and Australasian species of these three southern genera (the eastern Pacific species have been described elsewhere). The species-level taxonomy of several of these has been confused in the past; Afrolittorina africana and A. knysnaensis are here distinguished as separate taxa; Austrolittorina antipodum is a distinct species and not a subspecies of A. unifasciata; Nodilittorina pyramidalis is separated from the tropical Echinolittorina trochoides with similar shell characters. In addition to descriptions of shells, radulae and reproductive anatomy, distribution maps are given, and the ecological literature reviewed. -

Deviation of environmental salin- ity from the organismal optimum range results in an osmotic stress in osmo- conformers, which keep their fluids isotonic to the environment. The ability to overcome such stress is critical for animals inhabiting areas with considerable salinity variation, such as intertidal areas. In this study, we compared the reac- tion to mild water freshening (from 24 to 14 ‰) in two related species of inter- tidal snails, Littorina saxatilis and L. obtusata, with respect to several aspects: survival, behavior and proteomic changes. Among these species, L. saxatilis is Citation: Muraeva, O., Maltseva, A., Varfolomeeva, M., Mikhailova, N., more tolerant to low salinity and survives in estuaries. We found out that the Granovitch, A. 2017.

Allozymes are variants of an enzyme coded for by different alleles, they are generally considered to be under neutral or weak selection. Aspartate aminotransferase (Aat, EC 2.6.1.1) in the rough periwinkle, Littorina saxatilis (Olivi, 1792), has however shown to be under a very stringed selection regime, Aat is an essential part of the anaerobe energy production is molluscs. The two variants of Aat are found over a vertical gradient, Aat100 is predominant (0.7-0.8) in the surf zone while Aat120 is mainly found (0.8-0.9) in the splash zone.

Rocky Shore Snails As Material for Projects (With a Key for Their Identification)
Field Studies, 10, (2003) 601 - 634 ROCKY SHORE SNAILS AS MATERIAL FOR PROJECTS (WITH A KEY FOR THEIR IDENTIFICATION) J. H. CROTHERS Egypt Cottage, Fair Cross, Washford, Watchet, Somerset TA23 0LY ABSTRACT Rocky sea shores are amongst the best habitats in which to carry out biological field projects. In that habitat, marine snails (prosobranchs) offer the most opportunities for individual investigations, being easy to find, to identify, to count and to measure and beng sufficiently robust to survive the experience. A key is provided for the identification of the larger species and suggestions are made for investigations to exploit selected features of individual species. INTRODUCTION Rocky sea shores offer one of the best habitats for individual or group investigations. Not only is there de facto public access (once you have got there) but also the physical factors that dominate the environment - tides (inundation versus desiccation), waves, heat, cold, light, dark, salinity etc. - change significantly over a few metres in distance. As a bonus, most of the fauna and flora lives out on the open rock surface and patterns of distribution may be clearly visible to the naked eye. Finally, they are amongst the most ‘natural’ of habitats in the British Isles; unless there has been an oil spill, rocky sea shores are unlikely to have been greatly affected by covert human activity. Some 270 species of marine snail (Phylum Mollusca, Class Gastropoda; Sub-Class Prosobranchia) live in the seas around the British Isles (Graham, 1988) and their empty shells may be found on many beaches. Most of these species are small (less than 3 mm long) or live beneath the tidemarks. -

Mechanisms of gametic isolation (which are known to form rapidly in several models) take the central place in these debates. Nevertheless, the approximative capacity of a few investigated models to other taxa could be questioned, generating demand for the adop- tion of additional model organisms to study sympatric speciation.

DNA Barcoding Reveal Patterns of Species Diversity Among
www.nature.com/scientificreports OPEN DNA barcoding reveal patterns of species diversity among northwestern Pacific molluscs Received: 04 April 2016 Shao’e Sun, Qi Li, Lingfeng Kong, Hong Yu, Xiaodong Zheng, Ruihai Yu, Lina Dai, Yan Sun, Accepted: 25 August 2016 Jun Chen, Jun Liu, Lehai Ni, Yanwei Feng, Zhenzhen Yu, Shanmei Zou & Jiping Lin Published: 19 September 2016 This study represents the first comprehensive molecular assessment of northwestern Pacific molluscs. In total, 2801 DNA barcodes belonging to 569 species from China, Japan and Korea were analyzed. An overlap between intra- and interspecific genetic distances was present in 71 species. We tested the efficacy of this library by simulating a sequence-based specimen identification scenario using Best Match (BM), Best Close Match (BCM) and All Species Barcode (ASB) criteria with three threshold values. BM approach returned 89.15% true identifications (95.27% when excluding singletons). The highest success rate of congruent identifications was obtained with BCM at 0.053 threshold. The analysis of our barcode library together with public data resulted in 582 Barcode Index Numbers (BINs), 72.2% of which was found to be concordantly with morphology-based identifications. The discrepancies were divided in two groups: sequences from different species clustered in a single BIN and conspecific sequences divided in one more BINs. In Neighbour-Joining phenogram, 2,320 (83.0%) queries fromed 355 (62.4%) species-specific barcode clusters allowing their successful identification. 33 species showed paraphyletic and haplotype sharing. 62 cases are represented by deeply diverged lineages. This study suggest an increased species diversity in this region, highlighting taxonomic revision and conservation strategy for the cryptic complexes. -

A Test of Time-Series Data Against Models of Drift, Migration Or Selection
OPEN Heredity (2017) 118, 21–30 Official journal of the Genetics Society www.nature.com/hdy ORIGINAL ARTICLE What explains rare and conspicuous colours in a snail? A test of time-series data against models of drift, migration or selection K Johannesson1,2 and RK Butlin2,3,4 It is intriguing that conspicuous colour morphs of a prey species may be maintained at low frequencies alongside cryptic morphs. Negative frequency-dependent selection by predators using search images (‘apostatic selection’) is often suggested without rejecting alternative explanations. Using a maximum likelihood approach we fitted predictions from models of genetic drift, migration, constant selection, heterozygote advantage or negative frequency-dependent selection to time-series data of colour frequencies in isolated populations of a marine snail (Littorina saxatilis), re-established with perturbed colour morph frequencies and followed for 420 generations. Snails of conspicuous colours (white, red, banded) are naturally rare in the study area (usually o10%) but frequencies were manipulated to levels of ~ 50% (one colour per population) in 8 populations at the start of the experiment in 1992. In 2013, frequencies had declined to ~ 15–45%. Drift alone could not explain these changes. Migration could not be rejected in any population, but required rates much higher than those recorded. Directional selection was rejected in three populations in favour of balancing selection. Heterozygote advantage and negative frequency-dependent selection could not be distinguished statistically, although overall the results favoured the latter. Populations varied idiosyncratically as mild or variable colour selection (3–11%) interacted with demographic stochasticity, and the overall conclusion was that multiple mechanisms may contribute to maintaining the polymorphisms.
