Cipangopaludina Chinensis: Effects of Temperatures and Parasite Prevalence
Cipangopaludina chinensis: Effects of temperatures and parasite prevalence BIOS 35502-01: Practicum in Environmental Field Biology Jennifer Lam Advisor: Sara Benevente 2016 Lam 2 Abstract Comparison of parasite prevalence between native snail species, Lymnaea stagnalis, and invasive snail species, Cipangopaludina chinensis, was conducted by euthanizing snails one day after capture from Brown Lake. Looking at if parasitism is a main factor in intraspecific competition of C. chinensis at different temperatures, snails were captured, measured for height and width, housed under different temperature settings (20◦C, 25◦C, and 34◦C), and competed against other for a week-long trial. After the week-long trial or when the last snail died, snails were re-measured for growth and checked for parasites. Result from parasite prevalence between two snails species was significant, C. chinensis rarely had infections compared to L. stagnalis. From the result, native parasites were predicted to be highly specialized for L. stagnalis and lack mechanisms to penetrate C. chinensis. Result from the intraspecific competition suggested that parasite prevalence was not important as survival (in weeks) in the change in growth. Since parasite prevalence was low, and sample size was small, conclusion on parasite prevalence not being a factor in growth was not robust. Further studies on impact of C. chinensis on freshwater systems and native snail species are needed. Introduction Climate change is a concerning factor for freshwater ecosystems. Climate change increases the average temperature of water in some aquatic systems. With warmer water temperatures, more exotic species can establish as native species disappear (Rahel and Olden 2008). As native species disappear from the ecosystem, other species dependent on a specific native species may not be able to sustain the loss, leading to a decrease in biodiversity. -

Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. -

Echinostome trematode parasites have complex, multiple-host life-cycles, often involving migratory bird definitive hosts, thus leading to widespread distributions. Here, we examined the echinostome diversity in freshwater ecosystems at high latitude locations in Iceland, Finland, Ireland and Alaska (USA). We report 14 echinostome species identified morphologically and molecularly from analyses of nad1 and 28S rDNA sequence data. We found echinostomes parasitising snails of 11 species from the families Lymnaeidae, Planorbidae, Physidae and Valvatidae. -

During a survey of helminth parasites of the brown ground snake, Atractus major Boulenger, 1894 (Serpentes: Dipsadidae) from Moyobamba, region of San Martin (northeastern Peru), a new species of Glossidiella Travassos, 1927 (Plagiorchiida: Plagiorchiidae) was found and is described herein based on morphological and ultrastructural data. The digeneans found in the lung were measured and drawings were made with a drawing tube. The ultrastructure was studied using scanning electron microscope. Glossidiella peruensis sp. nov. is easily distinguished from the type- and only species of the genus, Glossidiella ornata Travassos, 1927, by having an oblong cirrus sac (claviform in G. -

It uses patterns of common ancestry as initial hypotheses in explaining evolutionary history. Such patterns, represented by phylogenetic trees, or cladograms, are postulates of persistent ancestral traits. These traits are evidence of historical constraints on evolutionary change. Patterns and processes consistent with a cladogram are considered to be consistent with an initial hypothesis of historical constraint. As an application of historical structuralism, a phylogenetic analysis is presented for members of the digenean plagiorchioid genera Glypthelmins Stafford, 1905 and Haplometrana Lucker, 1931. -

Concluding Remarks
Concluding Remarks The bulk of secretory material necessary for the encapsulation of spermatozoa into a spermatophore is commonly derived from the male accessory organs of re production. Not surprisingly, the extraordinary diversity in size, shape, and struc ture of the spermatophores in different phyla is frequently a reflection of the equally spectacular variations in the anatomy and secretory performance of male reproductive tracts. Less obvious are the reasons why even within a given class or order of animals, only some species employ spermatophores, while others de pend on liquid semen as the vehicle for spermatozoa. The most plausible expla nation is that the development of methods for sperm transfer must have been in fluenced by the environment in which the animals breed, and that adaptation to habitat, rather than phylogeny, has played a decisive role. Reproduction in the giant octopus of the North Pacific, on which our attention has been focussed, pro vides an interesting example. During copulation in seawater, which may last 2 h, the sperm mass has to be pushed over the distance of 1 m separating the male and female genital orifices. The metre-long tubular spermatophore inside which the spermatozoa are conveyed offers an obvious advantage over liquid semen, which could hardly be hauled over such a long distance. Apart from acting as a convenient transport vehicle, the spermatophore serves other purposes. Its gustatory and aphrodisiac attributes, the provision of an ef fective barrier to reinsemination, and stimulation of oogenesis and oviposition are all of great importance. Absolutely essential is its function as storage organ for spermatozoa, at least as effective as that of the epididymis for mammalian spermatozoa.
