UN1VERSITY OF HAWAl'l LIBRARY SYMBIONT-INDUCED CHANGES IN HOST GENE EXPRESSION: THE SQUID VmRIO SYMBIOSIS A DISSERTATION SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI'I IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN BIOMEDICAL SCIENCES (CELL AND MOLECULAR BIOLOGy) DECEMBER 2003 By Jennifer Loraine Kimbell Dissertation Committee: Margaret McFall-Ngai, Chairperson Edward Ruby Tom Humphreys AlanLau Katalin Csiszar Karen Glanz ABSTRACT All animals exist in lifelong relations with a complement ofbacteria. Because of the ubiquity ofthese symbioses as well as the derived biomedical applications, the study ofboth beneficial and pathogenic host-microbe associations has long been established. The monospecific light organ association between the Hawaiian sepiolid squid Euprymrw se%pes and the marine luminous bacterium Vibrio fiseheri has been used as a experimental model for the study ofthe most common type ofanimal-bacterial interaction, i.e., the association ofcoevolved Gram-negative bacteria with the extracellular apical surfaces ofpolarized epithelia. A fundamental step for understanding the mechanisms ofhost-symbiont associations lies in defining the genetic components involved; specifically defining changes in host gene expression. The studies presented in this dissertation identify and characterize V. fiseheri-induced changes in host gene expression at both the transcript and protein level. iii TABLE OF CONTENTS Abstract. ...................................... .......................................... -

REPORT ON CEPHALOPODS COLLECTED DURING 1906 BY THE UNITED STATES BUREAU OF FISHERIES STEAIVIER "ALBATROSS" IN THE NORTHWESTERN PACIFIC. By Madoka Sasaki, Of the Fishery Institute, Hokkaido Imperial University. INTRODUCTION. The zoological collection made by tlie United vStates Bureau of Fisheries steamer Alhatross during her cruise in the northwestern Pacific in 1906 comprised a large number of specimens of cephalo- pods. This collection throws much light on the faunal knowledge of that region. The specimens were placed by the aforesaid bureau under the charge of Prof. S. Watase, of the. Imperial LTniversity of Tok3"o, who subsequently handed them over to the writer, who in the meantime, while a student in that university, had l)egun the mono- graphic study of cephalopods. It is a pleasure to express my thanks to Professor Watase for man}' courtesies during the progress of the work. The specimens intrusted to me have been duh' examined and are referred to sixty species belonging to twenty-nine genera. Of the sixty species eighteen are new to science. These are listed as follows: Watasella nigra. Polypus alatus. Stauroteuthis albatrossi. Polypus tenuipulvinus. Polypus gl'iber. Polypus salchrosus. Polypus ahruptus. Polypus validus. Polypus ochotensis. Rossia molliceUa. Polypus tsugarensis. Rossia hipapillata. Polypus pustulosus. Sepia carinata. Polypus spinosus. Gonatopsis octopedatus. Polypus yendoi. Crystalloteuthis heringiana. Besides these there are two new varieties, namely. Polypus macro- pus, var. minor, and Sepia Jcohiensis, var. albatrossi, which are sepa- rated from their typical forms for convenience sake, pending a more accurate study based on a greater number of specimens than is accessible to me at present. -

Lefkaditou1, P. Maiorano2 and Ch. Mytilineou1 1National Centre for Marine Research, Aghios Kosmas, Helliniko, 16604 Athens, Greece. E-mail: [email protected] 2Department of Zoology, University of Bari, via E.Orabona 4, 70125 Bari, Italy. E-mail: [email protected] Abstract The intensive exploitation of the continental shelf has lead to a search of new fisheries resources in deeper waters. Four seasonal experimental surveys were carried out on the deep-waters of the Eastern Ionian Sea by Greek and Italian commercial trawlers from September 1999 to September 2000.Potential targets included deepwater species of fishes, shrimps and cephalopods. During the 4 cruises, a total of 26 species of cephalopods in 10 families were recorded, including 10 oegopsid squids, 3 myopsid squids, 5 octopods, 2 cuttlefishes and 6 sepiolids. Deep-water trawling resulted in the finding of some uncommon species such as Ancistroteuthis lichtensteini, Ctenopteryx sicula and Galiteuthis armata, which were recorded for the first time in the study area. Extensions of depth range were recorded for several species. The results of multivariate analyses, based on Bray-Curtis similarity indices, showed the presence of two clear associations: one consisting of hauls carried out at depths 300-550 m, where Sepietta oweniana, Todaropsis eblanae and Loligo forbesi are the most abundant species, and another with deeper hauls (up to 770 m depth) dominated by Neorossia caroli, Pteroctopus tetracirrhus and Todarodes sagittatus. -

E-mail: [email protected] 2Arion, C.P. 61, 70042 Mola di Bari, Italy. E-mail: [email protected] SUMMARY: Examination of 89 egg masses of Sepietta oweniana collected in the Catalan Sea (western Mediterranean) showed that 15.8% of them were composed of eggs at different developmental stages laid in more than one spawning bout; 6.7% of them were polyspecific and contained eggs of other sepioline species in addition to S. oweniana. The egg mass size, or number of eggs per egg mass, does not necessarily correspond to the spawning batch size, i.e. the number of eggs laid by a female in one spawning event. Furthermore the egg mass size appears to vary depending on the season. Keywords: Sepietta oweniana, egg mass, reproduction, batch fecundity, Mediterranean. RESUMEN: PUESTAS DE SEPIETTA OWENIANA (CEPHALOPODA: SEPIOLIDAE) COLECTADAS EN EL MAR CATALAN. – El examen de 89 puestas de Sepietta oweniana recogidas en el mar Catalán (Mediterráneo occidental) mostraron que el 15.8% estaba com- puesto de huevos en diferentes estadios de madurez, procedentes de mas de un episodio de desove; el 6.7% era poliespeci- fico y contenía huevos de otra especie de sepiolido además de los de S. oweniana. El tamaño de las puestas, o número de huevos por puesta, no es una mediada apropiada del tamaño de un desove, es decir, el número de huevos desovados por una hembra en un episodio de puesta. -

SEKI 3 ABSTRACT: Iridoteuthis iris (Berry, 1909) was originally described from a unique specimen collected in the main Hawaiian Islands, but the holotype is no longer extant. New material was collected from the southern Emperor-northern Hawaiian Ridge seamounts, extending the known range of I. iris by about 3200 km . The new samples are described, including the first description of adults. THE SPECIES COMPOSITION of the cephalopod another individual was collected in Mamala fauna around the Hawaiian Archipelago is Bay off the island ofOahu (ca. 60 km from the well known relative to that of many other type location) in a bottom dredge from the areas. Some species records, however, are vessel Janthina. This specimen was photo from unique specimens and/or juvenile indi- graphed (Figure I) and subsequently lost (B. viduals.

To unravel the biodiversity of sepiolid paralarvae collected in the Ría de Vigo during 10" the upwelling season (2012-2014), and to overcome the difficulties of traditional identification, sepiolid paralarvae 11" were identified by amplifying the barcoding gene cytochrome c oxidase subunit I (COI). In addition, morphometric 12" analysis (Generalised Lineal Models, GLM and Discriminant Analysis, DA) was used to identify morphometric 13" patterns useful for paralarval species identification. Genetic barcoding successfully identified 34 Sepiola pfefferi, 31 14" Rondeletiola minor, 30 Sepiola tridens, 4 Sepiola atlantica, 2 Sepietta neglecta and 1 Sepiola ligulata. COI analysis 15" also allowed us to infer that the paralarvae of the three most abundant species belonged to the same populations 16" independently of the year sampled. GLM suggested that total length (statistically different among the three species) 17" and tentacle length (statistically larger in S. pfefferi from the other two species) were good variables to distinguish 18" among species. -

Arctic cephalopod distributions and their associated predatorspor_146 209..227 Kathleen Gardiner & Terry A. Dick Biological Sciences, University of Manitoba, Winnipeg, Manitoba R3T 2N2, Canada Keywords Abstract Arctic Ocean; Canada; cephalopods; distributions; oceanography; predators. Cephalopods are key species of the eastern Arctic marine food web, both as prey and predator. Their presence in the diets of Arctic fish, birds and mammals Correspondence illustrates their trophic importance. There has been considerable research on Terry A.

E-mail: [email protected] as a by-catch. By contrast, data on the biogeography of Arctic cephalopods are doi:10.1111/j.1751-8369.2010.00146.x still incomplete. This study integrates most known locations of Arctic cepha- lopods in an attempt to locate potential areas of interest for cephalopods, and the predators that feed on them. International and national databases, museum collections, government reports, published articles and personal communica- tions were used to develop distribution maps. Species common to the Canadian Arctic include: G. fabricii, Rossia moelleri, R. palpebrosa and Bathypolypus arcticus. Cirroteuthis muelleri is abundant in the waters off Alaska, Davis Strait and Baffin Bay. Although distribution data are still incomplete, groupings of cephalopods were found in some areas that may be correlated with oceanographic variables. Understanding species distributions and their interactions within the ecosys- tem is important to the study of a warming Arctic Ocean and the selection of marine protected areas.
