From The Inside Out, And Through., Dominique Ovalle

The STEAM Journal

These photographs describe “Science” born of consumerism, hijacked by me, economically disenfranchised, or rather—temporarily embarrassed, artist. I was putzing around Malibu—my old college stomping ground, looking for free food; maybe a sample of some gourmet $5 chocolate, and all I got were these photographs.


Shrimp Immune System -Special Focus On Penaeidin, Yen-Ling Song, Ching-Yu Li Feb 2014

Shrimp Immune System -Special Focus On Penaeidin, Yen-Ling Song, Ching-Yu Li

Journal of Marine Science and Technology

In this review paper, we summarize the immune system of penaeid shrimp. This review includes the clotting system comprising clot protein and clotting enzyme (transglutaminase II), as well as the prophenoloxidase (proPO) activation system including proPO-activating enzyme (PPAE), proPO and clip domain serine protease homolog (c-SPH). In addition, several shrimp cytokines or cytokine-like molecules found in tiger shrimp Penaeus monodon participating in the defense responses are also discussed. C-SPH could enhance hemocyte adhesion. Shrimp astakine promoted hemocyte proliferation in the hematopoietic tissues and could be down-regulated at the post-transcriptional level by the binding of intracellular molecules such as transglutaminase I …


Marine Invertebrate Larval Distribution At The Hydrothermal Vent Site Of Gueishandao, Hans-Uwe Dahms, Li-Chun Tseng, Jiang-Shiou Hwang Feb 2014

Marine Invertebrate Larval Distribution At The Hydrothermal Vent Site Of Gueishandao, Hans-Uwe Dahms, Li-Chun Tseng, Jiang-Shiou Hwang

Journal of Marine Science and Technology

Scientists remain uncertain about numerous aspects of hydrothermal vent (HV) ecology, including the reproductive biology of their biota, as well as their recruitment and dispersal during larval stages (meroplankton) in the plankton above the HV sites. We studied the meroplankton from a shallow HV site off the northeastern coast of Taiwan, in the northwest Pacific Ocean. Our findings potentially explain how fauna endemic to HVs persist at specific HV sites. With the exception of some damaged Cnidaria and Ctenophora, the plankton net catches were in good condition and sufficient for identification.


Sequence Diversity Of Ammonium Transporter Genes In Cultured And Natural Species Of Marine Phytoplankton, Lee-Kuo Kang, Jeng Chang Feb 2014

Sequence Diversity Of Ammonium Transporter Genes In Cultured And Natural Species Of Marine Phytoplankton, Lee-Kuo Kang, Jeng Chang

Journal of Marine Science and Technology

The sequence database of ammonium transporter (Amt1) genes in eukaryotic phytoplankton was expanded by obtaining new sequences from cultured strains and natural populations collected in the East China Sea (ECS). From unialgal cultures, 6 new Amt1 sequences belonging to the Bacillariophyceae, Dinophyceae, and Prasinophyceae were obtained. A phylogenetic analysis revealed that AMT1s of higher plants were most closely related to those in green algae. In addition, haptophyte and diatom AMT1s formed distinct monophyletic clades. Diatom AMT1s were further divided into 3 orthologous subclasses, and active gene duplications were observed in subclass III. As for mixed-species sequencing using ECS samples, 78 …


Polychaetes As Annelid Models To Study Ecoimmunology Of Marine Organisms, Virginie Cuvillier-Hot, Céline Boidin-Wichlacz, Aurélie Tasiemski Feb 2014

Polychaetes As Annelid Models To Study Ecoimmunology Of Marine Organisms, Virginie Cuvillier-Hot, Céline Boidin-Wichlacz, Aurélie Tasiemski

Journal of Marine Science and Technology

Annelids are among the first coelomates and are therefore of special phylogenetic interest. They constitute an important part of the biomass of the seashore, estuaries, fresh water and terrestrial soils. Moreover, they occupy a central position in the trophic networks, as a major food source for fishes, birds and terrestrial fauna. Among Annelids, the large majority of polychaetes is restricted to the marine domain. This report gives an overview of the immune strategies developed by polychaetes to fight pathogens. The potential and interest to use these worms as biomarkers to monitor the influence of environmental perturbation on the immunity of …

Assessing The Potential Bacterial Origin Of The Chemical Diversity In Calcareous Sponges, Elodie Quévrain, Mélanie Roué, Isabelle Domart-Coulon, Marie-Lise Bourguet-Kondracki

Journal of Marine Science and Technology

The chemodiversity and cultivable bacterial diversity of temperate calcareous sponges were investigated in a time series of collection of two sponges, Leuconia johnstoni (Baerida, Calcaronea) collected from the northeastern Atlantic Ocean and Clathrina clathrus (Clathrinida, Calcinea) collected from the northwestern Mediterranean Sea, using combined chemical and microbiological approaches. Bacteria were visualized in tissue sections of these sponges with Gram staining and in situ hybridization. The sponge crude extracts revealed annually persistent biological activities against reference human pathogen strains: L. johnstoni extracts displayed antimicrobial activity against a Gram positive Staphylococcus aureus strain; C. clathrus extracts displayed a broad spectrum of antimicrobial …


Evolution Of Vacuolar Pyrophosphatases And Vacuolar H+-Atpases In Diatoms, Adrien Bussard, Pascal Jean Lopez Feb 2014

Evolution Of Vacuolar Pyrophosphatases And Vacuolar H+-Atpases In Diatoms, Adrien Bussard, Pascal Jean Lopez

Journal of Marine Science and Technology

To cope with changing environments and maintain optimal metabolic conditions, the control of the intracellular proton gradients has to be tightly regulated. Among the important proton pumps, vacuolar H+ -ATPases (V-ATPases) and H+ - translocating pyrophosphatases (H+ -PPases) were found to be involved in a number of physiological processes, and shown to be regulated at the expression level and to exhibit specific sub-cellular localizations. Studies of the role of these transporters are relatively scarce in algae and nearly absent in diatoms. Phylogenetic analyses disclose that diatoms, with both K+ -dependent and K+ -independent membrane integral pyrophosphatases, including proteins with high …


Diversity Of Bacterial Communities On Sunken Woods In The Mediterranean Sea, Sandrine Bessette, Sonja K. Fagervold, Chiara Romano, Daniel Martin, Nadine Le Bris, Pierre E Galand Feb 2014

Diversity Of Bacterial Communities On Sunken Woods In The Mediterranean Sea, Sandrine Bessette, Sonja K. Fagervold, Chiara Romano, Daniel Martin, Nadine Le Bris, Pierre E Galand

Journal of Marine Science and Technology

Sunken woods are very rich and diverse ecosystems supporting large macrofaunal diversity and representing a source of carbon and energy for any heterotrophic organism able to consume plant material, and those relying on specialized microbial taxa. However, relatively little is known about the microbial communities that degrade sunken woods and produce reduced compounds that serve as energy sources for chemosynthetic lifestyles. The purpose of this study was to explore the bacterial diversity developing on and within sunken woods in a NW Mediterranean submarine canyon and its adjacent slope by using 16S rRNA genes survey. We described communities from Pine wood …


Hydrothermal Vent Effluents Affect Life Stages Of The Copepod Tisbe Sp, Hans-Uwe Dahms, Li-Chun Tseng, Derek Moo-Chul Shim, Jiang-Shiou Hwang Feb 2014

Hydrothermal Vent Effluents Affect Life Stages Of The Copepod Tisbe Sp, Hans-Uwe Dahms, Li-Chun Tseng, Derek Moo-Chul Shim, Jiang-Shiou Hwang

Journal of Marine Science and Technology

We examined the environmental effects of various concentrations of hydrothermal vent (HV) effluents on growth, reproduction, and survivorship of the Tisbe sp. harpacticoid copepod that were retrieved from localities near the vent. Developmental stages (nauplii and copepodids) were exposed to various concentrations of HV effluents in a static renewal culture system. In the survivorship experiments, we tested 3 distinct developmental phases in HV effluent dilutions from 50% to 1%. The HV effluents considerably reduced the survivorship of the naupliar stages at concentrations of >1% (P < 0.05); all nauplii died at concentrations of 25% and 50%. The copepodids were considerably affected at concentrations of >1% in Tisbe sp. (P < 0.05), and no copepodid survived at 50% (P < 0.01). The adult females died at a 50% concentration in Tisbe sp. The developmental duration was not considerably affected in the naupliar or copepodid phases; however, it exhibited a trend of developmental delay. The naupliar development of Tisbe sp. was substantially delayed at a concentration of 10% (P < 0.01), whereas copepodids and adults only exhibited a trend of delayed development with increasing HV concentration. The endpoint mortality exhibited a greater sensitivity to chemical exposure than the endpoint development time. The early developmental stages of Tisbe sp. in both traits were more sensitive to HV effluents than advanced stages. Mortality was a useful toxicological endpoint compared that of developmental duration. We demonstrated that Tisbe sp. may be used in the monitoring of acute and life cycle effects of natural marine pollution caused by HV effluents.


The Ipocamp Pressure Incubator For Deep-Sea Fauna, Bruce Shillito, Françoise Gaill, Juliette Ravaux Feb 2014

The Ipocamp Pressure Incubator For Deep-Sea Fauna, Bruce Shillito, Françoise Gaill, Juliette Ravaux

Journal of Marine Science and Technology

Animal Biology studies have always benefited from the achievement of experiments on live animals, which obviously provide data on dynamic aspects of physiology. When it comes to deep-sea fauna, in vivo experiments are impaired, and in some cases impossible, due to the severe and often lethal stress experienced by animals throughout the sampling process. However, freshly collected deep fauna may be maintained alive and in good condition, by using specific aquaria which restore environmental conditions prevailing at depth in situ. Here we describe the pressure device named “Incubateur Pressurisé pour l’Observation et la Culture d’Animaux Marins Profonds”, or IPOCAMP, and …

Neurogenesis In Cephalopods: "Eco-Evo-Devo" Approach In The Cuttlefish Sepia Officinalis (Mollusca-Cephalopoda), Sandra Navet, Sébastien Baratte, Yann Bassaglia, Aude Andouche, Auxane Buresi, Laure Bonnaud

Journal of Marine Science and Technology

Cephalopods are new evolutionary and ecological models. By their phylogenetic position (Lophotrochozoa, Mollusca), they provide a missing master piece in the whole puzzle of neurodevelopment studies. Their derived and specific nervous system but also their convergence with vertebrates offer abundant materials to question the evolution and development of the nervous system of Metazoa (evo-devo studies). In addition, their various adaptions to different modes of life open new fields of investigation of developmental plasticity according to ecological context (eco-evo-devo approach). In this paper, we review the recent works on cephalopod nervous developmental investigations. We show how cephalopods, and especially Sepia officinalis, …


Traditional Vs New Approaches For Assessing Coral Health: A Global Overview And The Paradigm Of French Polynesia, Laetitia Hédouin, Véronique Berteaux-Lecellier Feb 2014

Traditional Vs New Approaches For Assessing Coral Health: A Global Overview And The Paradigm Of French Polynesia, Laetitia Hédouin, Véronique Berteaux-Lecellier

Journal of Marine Science and Technology

Today, there is increasing concern regarding the capacity of Scleractinian corals to sustain the growing number of insults associated with global and local changes (e.g. global warming, ocean acidification, pollution). If corals are to exist, there is an urgent need to use indicators of coral health that provide insight into early sub lethal shifts in corals before the irreversible effects of exposure manifest at the population and community levels. This paper will provide an overview of the most relevant and appropriate indicators of coral health currently used in traditional monitoring programs (traditional approach) or those that could be used in …

Crustacean Hyperglycemic Hormone: Structural Variants, Physiological Function, And Cellular Mechanism Of Action, Chi-Ying Lee, Kuo-Wei Tsai, Wei-Shiun Tsai, Jia-Ying Jiang,, Yan-Jhou Chen

Journal of Marine Science and Technology

Crustacean hyperglycemic hormone (CHH) is a peptide hormone originally identified in the X-organ/sinus gland (XO/ SG) complex of the eyestalks. It belongs to the CHH family which also includes molt-inhibiting hormone (MIH), vitellogenesis-inhibiting hormone (VIH), and mandibular organinhibiting hormone (MOIH), and ion transport peptide (ITP). Multiple molecular variants of CHH are generated by both post-transcriptional and post-translational mechanisms. In addition to the XO/SG complex, CHH gene is widely expressed in many extra-eyestalk tissues. Functionally, available data indicate that CHH is involved with the regulation of carbohydrate metabolism and stress-induced hyperglycemia. Several other physiological processes, including molting, ion and water balance, …

Journal of Marine Science and Technology

Coastal areas are the first marine systems being impacted by anthropogenic pollution and eutrophication. Organic matter poses a particularly negative impact on the environment due to its oxygen depleting and eutrophying effects. Shenzhen Bay mudflat contains rich organic matter. Here, we compare changes of polychaete assemblage parameters on seasonal data obtained from a Shenzhen Bay mudflat in a three-year study. The results based on the seasonal and spatial variations of polychaete species number, density and biomass, ShannonWiener diversity index, evenness index and richness index confirmed that high organic matter content impacted their distribution. A significant negative correlation between the density …

Journal of Marine Science and Technology

The genus Crypthecodinium (Dinophyceae) currently consists of only one species: C. cohnii, a heterotrophic marine dinoflagellate widely known able to produce prolific amount of DHA. However, previous studies revealed that there are morphological and genetic differences among Crypthedodinium cohnii-like strains, indicating the potential of undiscovered diversity of this dinoflagellate. Attempts of isolating heterotrophic marine dinoflagellate strains were made from submerged mangrove leaves and seaweed. A total of nine strains were established, cultured and maintained using seawater-based GTY medium for taxonomic identification and phylogenetic analyses based on SSU, ITS1, 5.8S, ITS2 and LSU rDNA. Morphological observation revealed all strains shared similar …

Genetic Diversity Of Filamentous Cyanobacteria From Shore Regions Of Okinawa, Shoichiro Suda, Rui Moriya, Shinpei Sumimoto, Osamu Ohno, Kiyotake Suenaga

Journal of Marine Science and Technology

Benthic marine cyanobacteria are ubiquitous oxygenic photosynthetic bacteria and they form major components of various communities, including epiphytic, epilithic and microbial mats, in coral reef environments. Filamentous groups may form almost monospecific macroscopic colonies, and sometimes make potentially harmful algal blooms (HABs). HABs bring serious problems for marine tourism but marine filamentous cyanobacteria are good resource for drug discovery. However, cultivation and identification of such filamentous cyanobacteria are difficult and there are taxonomic confusions. In this study, we investigate 17 samples from coral reef area of 10 localities in Okinawa. Macroscopic mats or cushions of filamentous cyanobacteria were collected. The …

Alternative Assessment Methods Applied To The Hairtail (Trichiurus Lepturus) Stock In The Aru Sea As An Example, Chao-Hsiung Cheng, Tsuyoshi Kawasaki, Kuo-Ping Chiang, Chuan-Hung Ho

Journal of Marine Science and Technology

The Aru Sea off Indonesia is a major fishing ground for Taiwanese distant-water otter trawlers. The hairtail, an economically important demersal fish, is abundant in that area. The assessment methodology in this paper extends previous studies on hairtail fisheries by considering migration within the fishing grounds. This model is based on conventional Leslie-Delury method but makes different assumptions on stock movement and the relationship between stock abundance and catch per unit effort. It was applied to retrospective data from the hairtail fisheries in the Aru Sea. In addition, the depletion method was used to estimate the abundance of hairtail and …
