ANTIOXIDANT CAPACITY in the HEMOLYMPH of the MARINE ISOPOD PENTIDOTEA RESECATA by Leah E. Dann a THESIS Submitted to WALLA WALL
ANTIOXIDANT CAPACITY IN THE HEMOLYMPH OF THE MARINE ISOPOD PENTIDOTEA RESECATA By Leah E. Dann A THESIS submitted to WALLA WALLA UNIVERSITY in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE April 26, 2017 ABSTRACT The isopod Pentidotea resecata inhabits Zostera marina eelgrass beds. Examination of oxygen levels in a Z. marina bed indicated that P. resecata frequently experience hyperoxia and potential hypoxia reperfusion events in these beds, which may lead to enhanced reactive oxygen species (ROS) production and increased oxidative damage if the antioxidant defenses cannot sufficiently suppress these toxic oxygen intermediates. The total antioxidant capacity of P. resecata hemolymph was compared to that of Ligia pallasii, a semi-terrestrial isopod living in normoxic conditions, and to that of Pandalus danae, a shrimp that lives below the photic zone. The hypothesis was that P. resecata hemolymph would have stronger antioxidant defenses than the other crustaceans because this isopod faces a more hostile oxygen environment. LCMS analysis of P. resecata hemolymph confirmed the presence of antioxidants including pheophorbide a, lutein, and β-carotene, while L. pallasii hemolymph contained pheophorbide a and lutein but no β-carotene. Pandalus danae hemolymph had no carotenoids or pheophorbide. Although L. pallasii hemolymph was missing β-carotene, it had a significantly higher total antioxidant capacity than that of P. resecata. Hemolymph from P. danae had an intermediate antioxidant capacity even though it contained none of the antioxidants detected in the other species. The unexpected antioxidant activities among the species could be explained by differences in metabolic functions or environmental factors that were not examined in this study; or perhaps P. -

Si bien la tendencia general de las capturas de abulón indica una disminución de las dos principales especies que la conforman (Haliotis fulgens y H corrugata), a partir de su máximo histórico en 1950, esta tendencia no ha sido uniforme ni entre especies ni entre las regiones de donde se extrae. -

This study identified and explored the phylogenetic relationship between novel CRESS-DNA viral genotypes associated with Pacific intertidal isopods Idotea wosnesenskii, Idotea resecata, and Gnorimosphaeroma oregonensis. One genotype associated with I. wosnesenskii, IWaV278, shared sequence similarity and genomic features with Tombusviridae (ssRNA) and Circoviridae (ssDNA) genomes and was putatively assigned to the Cruciviridae clade comprising chimeric viruses. The complete genome of IWaV278 (3478 nt) was computationally completed, validated via Sanger sequencing, and exhibited sequence conservation and codon usage patterns analogous to other members of the Cruciviridae. Viral surveillance (qPCR) indicated that this virus was temporally transient (present in 2015, but not 2017), specific to I. wosnesenskii at a single collection site (Washington, DC, USA), more prevalent among male specimens, and frequently detected within exoskeletal structures. -

Turf Assemblage of a Macrocystis Kelp Forest: Experiments On
AN ABSTRACT OF THE THESIS OF A. Keith Miles for the degree of Doctor of Philosophy in Wildlife Science presented on June 16. 1986. Title: A m Macrosti t° Ex nmen n and Herbivory. Redacted for privacy Abstract approved: E. Charles Meslow Early and later successional stages of the assemblage of turf algae and sessile animals of a Macrocystis kelp forest were studied off San Nicolas Island, California from 1980 through 1981, and 1983 through 1984. Kelps were manipulated to determine if differences in illumination could account for dominance by turf algae or sessile animals. Caging and algal-removal experiments were conducted to determine if the effects of herbivory and competition could account for the low or variable recruitment and abundance of foliose turf algae. Plots were covered for different time intervals up to 1 year to determine if survival of overgrowth could explain the prevalence of competitively subordinate crustose coralline algae. Increased cover and recruitment of turf algae and decreased cover and low recruitment of sessile animals were correlated with the removal of canopy. In the presence of canopy, existing cover of crustose algae and sessile animalschanged little over time; sessile animals recruited at significantly higher levels thanalgae on cleared plots. Patiria (a common invertebrate grazer) removed certain ephemeral algae and appeared to slow recruitment by other algae, but had little effect on mature turf algae. These effects appeared dependent on a high density of Patiria. Algal recruitment on caged and open, near-bare plots was negligible, but sessile animals recruited heavily to these plots. These results were correlated with low illumination caused by a dense and persistent surface canopy of Macrocystis. -
Coelenterata Actiniaria
Re< Well. Aust Mus. 1991. 15(1159-6~ Redescription of A ulactinia veratra n. comb. (=Cnidopus veratra) (Coelenterata: Actiniaria) from Australia. Suzanne Edmands* and Daphne Gail Fautint Abstract The actinian described as Ac/inia vera/ra Drayton, 1846, and currently referred to as Cnidopus vera/ra, belongs to the genus A ulac/inia. Discrepancies in the literature, particularly concerning ectodermal specializations of the column, led to taxonomic uncertainties about its placement. Nomenclatural re-evaluation was necessitated by recent synonymization of the genus Cnidopus with Epiac/is. Cribrina verrucula/a Lager, 1911, is synonymized with Aulac/inia vera/ra. Introduction In this study we evaluate the taxonomic and nomenclatural status of the actiniid sea anemone originally described as Actinia veratra Drayton in Dana, 1846, and currently commonly referred to as Cnidopus verater. The genus Cnidopus. created by Carlgren (1934) for Epiactis ritteri Torrey, 1902, has been synonymized with Epiactis (Fautin and Chia 1986). Carlgren (1934: 351) erected Cnidopus on the basis of "very numerous nematocysts present at the sides of the protuberances and between them in the lowest parts of the column", which he identified as "probably atrichs" (= atrichous isorhizas). These cnidae actually possess small spines (Bigger 1976, 1982) and so are correctly termed holotrichous isorhizas (= holotrichs). Carlgren (1949) omitted this species from his catalog of Actiniaria, but later (1950a, b) referred Actinia veratra to Cnidopus. In the process, he inexplicably changed the species name to verater, which Ottaway (1975) considered a deliberate emendation that should not supercede the original spelling. Carlgren subsequently (1950b, 1952) referred the Japanese sea anemone called Epiactis prolifera Verrill, 1869, (e.g. -
