We compared growth kinetics of Prorocentrum donghaiense cultures on different nitrogen (N) compounds including nitrate, ammonium urea, glutamic acid, dialanine, and cynate. P. donghaiense exhibited standard Monod-type growth kinetics over a range of nitrogen concentrations for all N. Compounds tested. Cultures grown on glu and urea had the highest maximum growth rates. However, cultures grown on cyanate had lower half saturation constants. Nitrogen uptake kinetics were measured in nitrate-deplete and replete batch cultures of P. donghaiense. In nitrate-deplete batch cultures, P. donghaiense exhibited Michaelis-Menten type uptake kinetics for nitrate, ammonium, urea and algal amino acids; uptake was saturated at …

A Case Study Of Rhincodon Typus Scarring In Ningaloo Reef: An Assessment Of The Current Scarring Classification System, Laura Korman
Independent Study Project (ISP) Collection
Rhincodon typus are the largest fish in the sea, but little is understood about this elusive species. They are known to annually aggregate in Ningaloo Reef, Western Australia—the location of this study. In order to better understand this species, scarring was observed on a subset of the population that aggregates in Ningaloo Reef. In addition, the scarring classification system was examined to determine if it is the most effective classification system. R. typus were observed, and photographed from April 9th-April 25th, 2014. These photos were then used for identification and scarring classification purposes. The analysis of the scars on R. …

Benthic And Planktonic Microalgal Community Structure And Primary Productivity In Lower Chesapeake Bay, Matthew Reginald Semcheski
Biological Sciences Theses & Dissertations
Microalgal populations are trophically important to a variety of micro- and macroheterotrophs in marine and estuarine systems. In Chesapeake Bay, microalgae facilitate the survival and development of ecologically and economically relevant fauna, including shellfish and finfish populations. While regarded as significant components of coastal environments, microphytobenthic communities are historically understudied. In Chesapeake Bay, the importance of phytoplankton to the ecosystem is understood, but the contribution of microphytobenthos remains unclear. This project surveys intertidal microphytobenthic communities, in relation to phytoplankton communities, around lower Chesapeake Bay describing the taxonomic makeup of these populations, coupled with quantification of cell abundance, biomass, and primary …

Determination Of The Ecological Condition Of Benthic Communities Affected By Polycyclic Aromatic Hydrocarbons In The Elizabeth River, Chesapeake Bay, Usa, Adam M. Webb
Biological Sciences Theses & Dissertations
The Southern Branch of the Elizabeth River, a tributary of Chesapeake Bay, has historically been polluted with hydrocarbon based industrial by-products. My study compared benthic community condition from two locations in the Southern Branch: the subtidal region near Money Point, historically affected by pollution of polycyclic aromatic hydrocarbons (PAHs), to a subtidal region near Blows Creek on the opposite shore that is putatively designated as unimpacted by P AH contamination. Samples from both study sites in the Southern Branch were compared to the benthic community condition of samples from the same habitat type designations collected as part of the Chesapeake …

Utilization Of The Invasive Alga Gracilaria Vermiculophylla (Ohmi) Papenfuss By The Native Mud Snail Ilyanassa Obsoleta (Say), Michele Guidone, Christine Newton, Carol S. Thornber
Biology Faculty Publications
The recent invasions of the red alga, Gracilaria vermiculophylla, to the Atlantic and Eastern Pacific Oceans have the potential to significantly alter intertidal and subtidal soft sediment communities. In particular, G. vermiculophylla increases habitat complexity and provides a novel hard substrate in an otherwise two dimensional habitat. Following our observations that the native omnivorous mud snail Ilyanassa obsoleta utilizes G. vermiculophylla for egg capsule deposition, our field surveys demonstrated that the in situ abundance of egg capsules on G. vermiculophylla matched abundances on a native alga Ceramium virgatumandwere at least 11–50 times greater than on all other co-occurring macrophytes. Additionally, …

The Ipocamp Pressure Incubator For Deep-Sea Fauna, Bruce Shillito, Françoise Gaill, Juliette Ravaux
Journal of Marine Science and Technology–Taiwan
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 …

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–Taiwan
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
Journal of Marine Science and Technology–Taiwan
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 …

Shrimp Immune System -Special Focus On Penaeidin, Yen-Ling Song, Ching-Yu Li
Journal of Marine Science and Technology–Taiwan
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 …

Evolution Of Vacuolar Pyrophosphatases And Vacuolar H+-Atpases In Diatoms, Adrien Bussard, Pascal Jean Lopez
Journal of Marine Science and Technology–Taiwan
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 …

Polychaetes As Annelid Models To Study Ecoimmunology Of Marine Organisms, Virginie Cuvillier-Hot, Céline Boidin-Wichlacz, Aurélie Tasiemski
Journal of Marine Science and Technology–Taiwan
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 …

Journal of Marine Science and Technology–Taiwan
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, …

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 …
