THE EFFECT OF UV RADIATION ON CYANOBACTERIAL MAT COMMUNITY STRUCTURE
Inman, Carrie Elise
Marine Biology
Cyanobacteria
UV Radiation
31 pages
Cyanobacteria are thought to have evolved during the early Precambrian, 2.5-3.8 billion years ago, when there were very high levels of UV radiation reaching the Earth's surface due to a lack of absorbing gases int he atmosphere. Oxygenic cyanobacteria were one of the few photosynthetic organisms that could survive under these harsh conditions. Cyanobacteria today have also been found to employ UV tolerant strategies to cope with the damaging effects of UV radiation. In this study three cyanobacterial mats were investigated to determine if UV had an effect on the mats in the field and subsequently on clonal isolates cultured from these mats in the lab. UV exclusion experiments, using UV blocking and UV transmitting filters, were carried out in the field over a two-month period. Protein and pigment analysis on the core samples collected from the field UV treatments showed no significant difference between the treatments. However, samples collected of new settlement cell material on ceramic tiles, did show a significant different between the two UV treatments. UV exclusion experiments run using two strains of clonal isolates of Lebtolyngbya sp. cultured from Mushroom Spring did show a highly significant detrimental effect of UV on growth measured by dry weights. In addition, the two strains, one cultured from the UV(-) field material and one cultured from the UV(+) material, were effected differently by UV radiation in the lab UV exclusion experiment. The isolate cultured from the UV(+) mat material was less effected by UV radiation, as measured by dry weight accumulation over time. This may imply the use of a unique UV tolerant strategy employed by this strain.

A CRITICAL REVIEW OF HOMING AND FORAGING BEHAVIOR IN LIMPETS (MOLLUSCA; GASTROPODA} : A CENTURY OF OBSERVATIONS , EXPERIMENTS , AND CONTROVERSIES (1894 TO 2001)
April, Jane Wright
Limpets
Biology
Marine Biology
97 pages
Homing limpets are characterized by their predictable stationary resting behavior in their home territory during periods of inactivity, followed by active feeding excursions ranging up to a few meters away from home . They almost always return to their previous resting spot (home scar) during a tidal cycle. Limpets are grazers that use their radula to scrape and feed upon microalgae, macroalgal settlers, bacteria, cyanobacteria, diatoms and other phytoplankton, and animal larva that settle inside their grazing grounds, called the feeding arena.
Home scars lie within the feeding arena and vary according to species . Most limpets live on rock, some live on macroalgal fronds, and some even live on the shells of other gastropods. Some home scars are visible as a chiseled indentation in rock that fits the shape of the limpet's shell perfectly. This depression is caused by the repeated scraping of the returning limpet's shell at the home scar. Other homing limpets do not make a strict scar, rather, they home to a region rather than a spot. Certain homing limpets will join clusters of conspecifics, returning to roughly the same position within the cluster from day to day.

MERCURY IN THE ENVIRONMENT
Tsuneyoshi, Kunio
Marine Biology
Mercury
75 pages
The chances of us being exposed to mercury and its compounds are significant. During the past, farmers, miners, and manufacturers have used millions of pounds of mercury annually. Mercury containing agricultural chemicals are used widely because of their antifungal activity and mercury is used extensively in the manufacturing of many inorganic and organic chemicals, pulp, felt, and electrical appliances. The pollution resulting from these applications eventually finds its way into our food and water supply. The different forms of mercury which get into the environment can be converted to the more dangerous methylmercury by microorganisms. The ingestion of polluted freshwater and saltwater fish is probably the main route by which mercury enters the human body. In heavily polluted water the mercury level in fish can be very high.

The Effects of Mammalian Predators on a Southern Oregon Colony of Leach's Storm- Petrels (Oceanodroma leucorhoa)
Pollard, Anne M. (Anne Marie), 1984-
xii, 100 p. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number.
Saddle Rock, with an estimated 86,300 birds, was the third largest colony of
Leach's Storm-petrels (Oceanodroma leucorhoa) in Oregon in 1988. This colony is
uniquely vulnerable to terrestrial predation due to its contiguity with the mainland during
low tides. In recent years, an increase in visitation of raccoons and river otters to Saddle
Rock has resulted in increased bird mortality. In 2007 I estimated predation rates ranging
from 0 to 59 birds per night, with predation occurring on 7 of 11 nights checked. 48% of
marked burrows were depredated throughout the season. In 2007 and 2008, I monitored
nesting density and burrow occupancy rates on Saddle Rock and compared these data
with those from nearby Hunters Island, a similarly sized colony. Saddle Rock now hosts
significantly lower densities than Hunters Island. Comparisons of recent Saddle Rock
data with those from 1979-1995 show a steep population decline.

Structure and Dynamics of the Marine Anaerobic Microbenthos
Cooke, John H.
Marine Biology
High energy windows
43 pages
Nearly all ecosystems of land and water including the open sea show a vertical zonation of physical and chemical factors and of flora and fauna. In such transitory zones there frequently exists interfaces where air meets land or light meets darkness or one physical condition gives way to another. Such an interface occurs within the sands and sediments of sea basins. The oxygenated surface layers of marine sand bottoms and beaches give way in deeper layers to anaerobic-reducing conditions with the exception of surf swept high energy beaches. Such interfaces frequently have biological significance.
The extent of the anaerobic-reducing biome is indicated by the size of the ocean basins themselves excluding areas without sediment and the "high energy windows" of surf swept beaches. In comparison, the anaerobic biome far exceeds the size of the aerobic surface sediments, although a great deal more scientific work has been done in oxygenated sediments.

PACIFIC NORTHWEST COASTAL TEMPERATURES: INVESTIGATION OF INTERDECADAL CYCLES AND BIOLOGICAL IMPLICATIONS
Shotwell, Kalei
Marine Biology
Marine Ecology
Climate Change
Ocean Temperature
33 pages
Investigations regarding interdecadal climate cycles have surged in the past several years providing alternative perspectives into the forcings on climate change. The possible couplings between the various patterns of these physical processes (oceanic, atmospheric), terrestrial, and biosphere regimes are of substantial importance. This study seeks to explore the relationship between the ocean and the land-surface on a regional scale. It is hypothesized that Pacific Northwest coastal sea surface temperatures and surface-air temperatures are temporally identical, or merely offset by a time lag, with the same pattern and period. Correlation and regression analysis were completed for the chosen sites, and significant positive correlation (r: 0.843) was determined. The similar cycles of the marine and terrestrial environments have significant biological implications. The progress with and problems of biological climate patterns is discussed along with the importance of proxy indicators, and relevancy to fisheries and management.

Tube hood orientations of Pista pacifica (Polychaeta: Terebellidae)

Pista pacifica
Polychaeta
vi, 58 p. ; ill., maps. A print copy of this title is available from the Oregon Institute of Marine Biology library, under the call number OIMB QL391.A6 W5.
The tube hood orientation of Pista pacifica is non-random and related to current direction. Results from field measurements and
from one flow tank experiment suggest that Pista pacifica build their tube hoods at right angles to local currents, and perhaps away from the direction of any sediment transport which may occur normal to the prevalent current direction. By orienting their tube hoods perpendicular to water currents, the animals may be making use of the kinetic energy of the water motion around them to generate a tube ventilation current. This current may in turn lessen the energetic needs of the worms by providing internal ventilation and sediment flushing currents at little energetic cost to the organism.

Growth of phytoplankton can go on reasonably with only very small quantities of nutrients amounting to a: few milligrams of phosphorus as phosphate per cubic meter of sea water and usually a somewhat larger amount (about eight times by weight) of nitrate nitrogen. Their remarkable growth as compared with the growth of land plants at such great dilution is partly explained by t he microscopic size of the phytoplankton cells, which makes for better diffusion of nutrients a s well as a greater surface to volume ratio which promotes absorption (Raymont, 1963).

The role of an estuary or bay in the life cycle of Cancer magister is not well understood. I believe Coos Bay, as well as other bays, is an important "nursery" ground for young crabs, its recruits are necessary for sustaining a commercial fishery. Tasto (1978) has shown that juveniles account for a larger percentage of an estuary's crab population than in nearshore waters. The juveniles in the S.F. Bay-complex exhibited a growth rate nearly twice that of ocean-reared crabs (Tasto et al 1981). It is postulated that this is due to reduced predation pressure and increased food supply within the estuary.

ESTUARINE MICROPHYTE PRODUCTIVITY
Gibson, Steven Charles
Marine Biology
Microphyte
Estuarine Cycle
Estuarine Circulation
58 pages
An estuary is an interface where mixing of river and sea water occurs, often within the confines of an embayment. The abrupt environmental changes between these two environments pose a multiplicity of stresses to the estuarine biota, placing a premium on the ability to adapt to a wide range of conditions.
Few species have sufficient adaptability to meet these conditions and so estuarine species diversity is low (Odum, 1970). Additionally, estuaries are "young" ecosystems in that pioneer species are always present because constant flushing by fresh water and the tides precludes a successional sequence from going to climax. Such "young," low diversity ecosystems are characterized by large standing crops of short lived species (resulting in short nutrient recycling times), and high primary productivity. Table l provides some net primary productivity values for various estuaries and other ecosystems. Microphytic net production plus macrophytic net production is often very high in estuaries, albeit less than tropical rain forests and many agricultural crops.

Detritus, a Critical Essay

Detritus
Marine Biology
Marine Ecosystem
51 pages
Detritus plays an important role in the marine ecosystem. It forms a significant fraction of the available food sources (Darnell, 1958, 1961 , 1967; Gant et. al, 1971; Heald
1971; Lenz, 1977; E. P . Odum and Dela Cruz, 1967; W. E. Odum,
1971; W. E. Odum and Heald, 1975; Riley, 1970; Seki, 1972·; Teal, 1962). Detritus is the chief link between primary and secondary productivity in salt marshes and mangroves. This is because only a small portion of the net production of the marsh grass or mangrove is grazed while it is alive. The major energy flow between autotrophic and heterotrophic levels is by way of the detritus food chain (Gant et al, 1971; Heald, 1971; E. P. Odum and Dela Cruz, 1967; W. E. Odum, 1971; W. E . Odum and neald, 1975; Teal, 1962)

WINTER POPULATION DYNAMICS OF PHYTOPLANKTON IN COOS BAY, OREGON
Freeman, Peter C.
Marine Biology

35 pages
This study is concerned with the early winter (October, November, December) dynamics of phytoplankton populations in the South Slough of the Coos Bay estuary. A student study, conducted at the Oregon Institute of Marine Biology in July and August 1973 established the size, location and make-up of the phytoplankton population present during the summer months . It is hoped that this study, when combined with the findings of the OIMB summer study, will lead to the formulation of a summer- fall-winter trend in the phytoplankton populations in the South Slough.

Colonial Ascidian Dispersal: What are the effects of adult population density and isolation on recruitment?
Braudrick, Nate

Population Density
Colonial Ascidians
29 pages
Invasive species are thought to be one of the largest ecological threats to healthy ecosystems today. This paper is an attempt to show how anthropogenic transport of species with short dispersal distances is the most important factor in their colonization of new areas. In the Charleston, Oregon marina three study sites were set up to attempt to show the significance of isolation and adult population density on the recruitment of colonial ascidians, an encrusting member of the fouling community. Significant results were found supporting the hypothesis that greater adult population density results in increased recruitment. The second hypothesis of isolation decreasing the recruitment of colonial ascidians was not supported with significant results.

Factors Affecting the Retention of Eukaryotic Phytoplankton within the Euphotic Zone
Corbett, Andrea Cathryn
Marine Biology
Phytoplankton
67 pages
Phytoplanktonic species face a serious problem in balancing photosynthetic light requirements with nutrient needs. Optimal light intensities are found toward the surface, while nutrients are usually in greater concentrations below the epilimnion. Motile species, such as the flagellates or gas vacuolate blue-green algae, collect at depths which optimize these needs, or migrate vertically to take maximal advantage of each in turn. Phytoplankton, with few exceptions, are denser than their media and without various internal and environmental suspension factors, non-motile species sink irrevocably from the euphotic zone.
The subject of phytoplanktonic suspension has been reviewed by Hutchinson (1967), who dealt with limnetic species, and Smayda (1970) , who considered the problem in marine organisms. Research published after these papers appeared has added new dimensions to our understanding of the problem, and has stimulated the writing of this critical review. Since many of the suspension factors recognized are employed by both marine and fresh water species, it is convenient and useful to combine them into one paper. The prokaryotic phytoplankton are not considered here for a current and detailed analysis of gas vacuoles, the floatation bodies of prokaryotes, has been prepared by Walsby (1978).
Many factors , both physical and biological, are implicated in maintaining epilimnetic populations of nonmotile phytoplankton. The primary mechanism is wind-induced turbulence. Even fairly light winds create Langmuir spirals which circulate and retain motile and nonmotile cells in an even distribution throughout the upper waters. Non-motile cells are dependent upon turbulence, and normally bloom only when a substantial mixing of nutrients and cells occurs in the euphotic zone. Motile cells lose position al control in turbulence but may become dominant in calm, stratified conditions. The many mechanisms which reduce sinking rate s in still laboratory media become effective in nature only as turbulence decreases. These secondary retention factors include cell size , shape, density, colony formation, mucous secretion, age, selective ion accumulation, fat storage, light, nutrient availability , etc. Each of these mechanisms are discussed and where possible their values to different groups of phytoplankton are compared.

The High Nutrient Low Chlorophyll (HNLC) Phenomenon and the Iron Hypothesis
Stenn, Erik Stricker
Marine Biology
CO2 Cycling
Iron Hypothesis
High Nutrient Low Chlorophyll Phenomenon
HNLC Phenomenon
47 pages
With rising CO2 levels in the atmosphere it becomes increasingly more important to understand the nature of the oceans as a sink for CO2 as well as the mechanisms that transport carbon from the atmosphere to the oceans. Regions of ocean in the subarctic Pacific, eastern equatorial Pacific and the southern Ocean have been recognized as being abnormally low in total biomass and yet they maintain high levels of available macronutrients. Due to the characteristic high nutrient low chlorophyll content of these regions, they have been dubbed HNLC. The 'biological pump' concept is a proposed mechanism serving as a carbon sink and was assumed to be limited by nitrogen. Early shipboard container experiments demonstrated that iron might be the limiting nutrient and not nitrogen. The data from the early experiments proved to be inconclusive due to imprecise methodology. In the late 1980' s there was renewed interest in HNLC areas championed by J.H. Martin. He maintained that HNLC regions exhibit Leibig limitation by iron, where, standing crops of phytoplankton are constrained by availability of iron: if iron were available, the standing crops of phytoplankton would increase and nitrate would be depleted despite grazing. Others argue that HNLC regions are a manifestation of active grazing in a steady state ecosystem. An intermediate camp claims that HNLC regions are a result of combined physical and biological processes that prevent the utilization of the surface macronutrients. The debate surrounding this issue prompted Martin and colleagues to perform the IronEx experiment: the in situ use of iron to enhance an HNLC patch in the Galapagos region of the Pacific. The ecosystem demonstrated an unequivocal response to iron; however, macronutrients were still relatively abundant after the experiment. Subsequent studies have revealed that iron impacts all cell size groups of phytoplankton and constrains new production in HNLC areas. What remains unclear is the effect of grazing within these ecosystems.

TERRITORIALITY AND AGGRESSIVE BEHAVIOR IN MALE PINNIPEDS

Reproductive Behavior
64 pages
The three families of pinnipeds include the Phocidae, "true seals", the Otariidae, sea lions and fur seals, and the Odobenidae, or of polygyny similarities in walruses. It is remarkable that the evolution in pinnipeds has generated such marked their behavior, while simultaneously creating extreme differences in the social and reproductive organization between the different taxa. The evolutionary relationship of the three families is not yet fully understood, for the fossil evidence is not complete. As a result, many ethologists theorize about the evolution of polygyny in pinnipeds while attempting to understand the evolutionary background of behavior. Most ethologists share a phyletic method of inferring behavioral evolution which has been described by Hinde and Tinbergen (1958) as follows, ...(sic)"by comparing the behavior traits of species whose phylogenetic relations are established (usually on the basis of morphology), it is possible to make hypotheses about the probable origins o f that behavior, and thus about the course of evolution."

Grazing of Zooplankton in the Oceanic Environment
de Kort, Franciscus M. Th.
Marine Biology
Zooplankton
Grazing
48 pages
Grazing in the oceans, in general, refers to herbivores feeding on plant material. It is an important factor in determining primary production in the sea, and is difficult to estimate. Also, this energy transfer seems at least in part to be responsible for population changes which occur in the ocean.
Since it is only in the coastal waters that other plant material besides the phytoplankton is abundant (seaweed) and that other zooplankton organisms besides the copepods are
abundant (meroplankton: the planktonic larval stages of Mollusca, Echinodermata and worms), attention will be primarily focused on the relation between phytoplankton organisms and copepods. (Marshall and Orr, 1966b) Most experimental work has been done with cope pods, al though other plank tonic animals (Euphausids, Chaetognaths etc.) are abundant at certain places for part of the year.
In order to understand the problems involved in studying the quantitative aspects of grazing, a general discussion of the patterns of feeding is necessary (Chapter I).
The second chapter provides the theoretical background. (mathematical models) for a discussion of the methods used and measurements obtained in chapter three.
The last chapter discusses grazing as it relates to the ecological problem of population control and evaluates the progress made in this area of research.

Review of factors contributing to the settlement and recruitment of barnacles
Trainer, James
Marine Biology
Marine Ecology
Barnacles
33 pages
Barnacles are popular study organisms for a variety of reasons. As adults, they are sessile, and they are often small and numerous, making them easy to manipulate in ecological experiments. A researcher can be sure that an adult barnacle that disappears between observations has died, and has not moved away. As larvae, they develop through a series of six naupliar instars in the plankton. Nauplii are easy to identify in plankton samples, and are easy to collect from the egg lamellae of adult barnacles and culture in the laboratory. Nauplii metamorphose into the non-feeding cyprid stage, at which point they attempt to contact and stick to hard substrata. Depending on condition of the substrate, cyprids metamorphose into juvenile barnacles or return to the water column. A juvenile barnacle feeds and grows at its site of metamorphosis until it dies.

Two genera of fishes in the family Salmonidae have stimulated considerable biological interest on the Pacific coast of North America. The anadromous life histories of both the Pacific salmons (Oncorhynchus spp.) and the migratory rainbow trout (Salmo gairdneri) have provided many research opportunities during the past several decades. Although the life histories of these two genera of fishes are quite similar, a basic difference is reflected in their post-spawning mortalities. While the universal post-spawning mortality of adult Pacific salmon restricts them to a single spawning, some of the anadromous trout may spawn repeatedly, but post-spawning mortality may amount to as much as 50%. The ability of the steelhead trout to survive under the same environmental stresses that result in the death of Pacific salmon represents -- a still somewhat Puzzling species difference of vertebrate physiological uniqueness. This paper will attempt to review current and past work on this question of survival vs. death in these anadromous fishes which comprise one of our most valuable local natural resources.

Symbiosis, the cohabitation of two or more different organisms, is represented across species as well as phyla. A unique symbiosis has developed in the marine environment between the phylum Cnidaria and members of the Division Dinophyta ("zooxanthellae"). The relationship is one of mutualism, as both organisms benefit from the relationship. Although cnidarians, such as sea anemones, hard and soft corals, scyphozoans, and hydrocorals, comprise the majority of hosts that take part in this symbiosis, some nudibranchs and sponges also contain endosymbiotic dinoflagellates. Alternatively, some cnidarians may contain chlorophyte endosymbionts. The symbionts are usually held with vacuoles inside the host endoderm cells (Glider et al., 1980; Trench, 1987), but they have also been found within the epidermis and mesoglea of some cnidarians.

HEMOGLOBIN TRANSFORMATION DURING METAMORPHOSIS IN ANURANS

51 pages
Hemoglobin (Hb), one of the most abundant vertebrate proteins, distributes oxygen among body tissues following oxygenation at the respiratory interface between organism and environment. During the course of natural selection, the Hb molecules of a particular species take on biochemical and biophysical parameters which facilitate adaptation to a unique environmental regime. Extensive research has shown that during the life history of a particular organism there may be a progressive expression of Hb types as characteristic alterations in oxygen availability and oxygen demand occur. Such is the case among anurans; during the discrete postembryonic transition period known as metamorphosis , new molecular forms of Hb appear which persist in the adult frog.

'Ligia'
Heide, Allen
Marine Biology
Adaptation
Ligia
Physiology
33 pages
Adaptation to land from a water environment is a common topic in many textbooks. Most of the organisms discussed, though, have already adapted themselves to solve the most vital problems of water retention and temperature control. Animals such as mammals, reptiles, and birds have all developed outer coverings that are permeable to water and allow these animals a great deal of independence from their water sources. Mammals and birds have physiological adaptations that allow them to regulate their body temperature, while reptiles have relied mostly on behavioral patterns to cope with this problem.
In this paper I would like to discuss the Isopod Ligia that is considered terrestrial in habitat, but is yet to evolve a complete independence from the sea.
Ligia belongs to the family Oniscoidae, which is the Family of Crustacea containing species living a completely terrestrial life. Within the Isopods there are species such as Carolana harfordi and Idothea wasnesenskii that live a marine existence and others such as Porcellio and Amadillidium that are completely terrestrial. Ligia represents an interesting point of study in that it appears to be an intermediate species in the transition from the sea to land.
I would like to discuss some of the physiological and morphological characteristics of Ligia that place it in the intermediate position and its general habitat and behavioral patterns that may help to give a fuller understanding of this unique genus.

SOME ASPECTS OF THE ECOLOGY AND BIOLOGY OF TWO CANCER SPECIES

Dungeness Crab
96 pages
As a commercially exploited species the Dungeness Crab, Cancer magister, has generated a fairly large, unconsolidated body of literature. Initial research undertaken in British Columbia, Washington, Oregon and California dealt with general biology and the fishery, with the goal of determining the adequacy of fishery regulations. At that time no danger of overfishing was thought to exist, although fishery effort was intensifying (Cleaver 1949). A number of authors also noted a coastwide cycling in abundance of crab landings. However, after the 1960-1961 season the central California fishery did not recover from low levels of abundance associated with a cyclic minimum. Concern for this fishery prompted a new wave of investigations of population dynamics, making use of recent ecological theory, computer analysis and modeling techniques. The possibility that the fishery could alter natural population cycles, resulting in drastically lowered population levels throughout the species' range, was suggested. The purpose of this paper is critically to review the ecology and exploitation of magister using the information gathered throughout the last 60 years

Distribution of Zooplankton and Detritus within Langmuir Circulation Cells
Laferriere, Alison Mariah, 1976-
xi, 70 p. : ill., maps. A print copy of this title is available from the UO Libraries under the call number: SCIENCE GC228.5 L34 2007
Langmuir circulation cells are wind generated surface currents, which take the form of alternating clockwise and counter clockwise rotating helical cells. Models suggest that organisms and particles may be retained in the convergence and divergence zones depending on the relative settling and swimming velocity versus circulation velocity. Surface water in convergence and divergence zones of Langmuir circulations were sampled with plankton nets and zooplankton and fecal pellets were enumerated. Copepods did not differ significantly between zones. Balanus glandula cyprids, competent Polydora spp., and an unidentified late stage veliger were often significantly concentrated in convergence zones. These results suggest that late stage larvae may be exploiting Langmuir circulation as a transport mechanism to travel shoreward for settlement. Fecal pellets were more concentrated in divergence zones on four out of six sample days. On the two days when pellets were more concentrated in convergence zones the swell was larger.

Prolactin and Osmoregulation in Teleost Fishes
Teleost
Prolactin
Osmoregulation
36 pages
Teleosts as a group live in a wide range of aquatic media and maintain their osmotic pressure and electrolyte concentration at l evels largely independent of the composition of their environment. In order to maintain hydromineral balance, teleosts are equipped with specialized ion and water-transporting epithelia situated in the gills, skin, kidney, intestine, and urinary bladder. In Euryha line fishes, the function of these osmoregulatory organs must change according to environmental demands.
Comparative physiologists have studied the endocrine control of osmoregulation in fishes for several decades. One of the findings from a large body of results is the demonstrated effect of prolactin on electrolyte and water metabolism. Interest in prolactin as an osmoregularory hormone in fishes started when Burden (1956) reported the failure of hypophysectomized killifish, Fundulus heteroclitus to survive in freshwater. In further work, Pickford and Phillips (1959) indicate d that only prolactin is effective in promoting the freshwater survival of hypophysectomized Killfish. Since these early investigations, mammalian prolactin has been shown to restore freshwater survival in several other hypophysectomized teleosts: Poecilia latipinna (Ball and Olivereau, 1964), Xiphophorus maculatus (Schreibman and Kallman, 1960), Tilapia mossambica (Dharmamba et.al., 1967).

Barnacle Feeding: Comparing Cirral Anatomy, Feeding Behavior, Reynolds Numbers, and Cirral Fan Leakiness Across Three Size Classes of Three Species of Common Acorn Barnacles
Comparing Cirral Anatomy, Feeding Behavior, Reynolds Numbers, and Cirral Fan Leakiness Across Three Size Classes of Three Species of Common Acorn Barnacles
Geierman, Christina, 1982-
xv, 97 p. : ill. A print copy of this title is available through the UO Libraries under the call numbers: SCIENCE QL444.C58 G45 2007
This thesis investigated feeding behavior, cirral anatomy, Reynolds numbers (Re's), and leakiness of the cirral fan for three barnacle species: Balanus glandula, Semibalanus cariosus, and Balanus nubilus. A study of the feeding of B. glandula revealed that newly-metamorphosed juveniles fed at Re's less than one and their cirral fan leakiness was <5% at current speeds of 4 cm/s. At this speed, large and medium individuals fed at Re's near unity, and their cirral fans were 6.8±O.7% leaky. The experiments were repeated using S. cariosus and B. nubilus with the same tissue mass as B. glandula. No clear species-specific or size-specific trends were identified in these species. The observed switch from low to high Re feeding in B. glandula may indicate a lower limit to the size of this species, if further research confirms low Re feeding is less efficient and field current velocities are sufficiently low.

A REVIEW OF MODELS ON THE SELECTION OF HERMAPHRODITISM AND THEIR APPLICATION TO A MARINE GASTROPOD: HERMISSENDA CRASSICORNIS
Schmit, Valerie M.
Hermaphroditism
Marine Biology
Hermissenda Crassicornis
26 pages
The current literature covering certain models for the selection of hermaphroditism was reviewed. The purpose of the review was to assess the models' ability to determine if there are constraints present that pressure a particular species to remain hermaphroditic. The models of Michael Ghiselin, E.L. Charnov, J.J. Bull, and J. Maynard Smith were examined in order to test their applicability to the nudibranch Hermissenda crassicornis. The ecology of H. crassicornis was reviewed in reference to the models so that their fit in relation to what is known about H. crassicornis could be evaluated.

EUTROPHICATION: CHANGES IN ESTUARINE PHYTOPLANKTON PRODUCTIVITY
McLean, April G.
Eutrophication
Phytoplankton
Marine Biology
21 pages
Estuaries are individually unique ecosystems, each with specific environmental characteristics. There are, however, some generalizations that can be made describing estuaries overall. Caspers (1967) gives four features applicable to estuaries : 1) limited to rivermouths in tidal seas; 2) saline areas present, their extent dependent on the amount of freshwater runoff; 3) the upper limit of the estuary is defined by the upper limits of tidal influence into freshwater zones; 4) characterized by changeable salinities and instability of environmental factors. Brackish systems have been put into three categories by a number of workers (cf. Emery, et.al.(1957), Pritchard (1967)) breaking them into positive, inverse and neutral groups. Positive estuaries are river dominated, freshwater runoff exceeding evaporation rate. Inverse estuaries are characterized by rapid evaporation rate, surpassing runoff and precipitation. These are hypersaline the majority of
the time. Neutral estuaries have a balance between evaporation and freshwater influx. These classifications, however, are oversimplifications. Pritchard (1967) defines an estuary as a "semi-enclosed coastal body of water which has a free connection with the open sea and within which seawater is measurably diluted with freshwater derived from land drainage." Pritchard's definition restricts the term "estuary" to signify only the so-called "positive estuary". Emery, et. al. (1957) use the term "normal estuary" to be equivalent to positive estuary.

THE DIETS OF THE SHINER SURFPERCH (Cymatogaster aggregata Gibbons) AND THE STAGHORN SCULPIN (Leptocottus armatus Girard) IN THE UMPQUA RIVER ESTUARY, OREGON 1981-1982

This was the first diet study on the shiner surfperch and the staghorn sculpin in the Umpqua River Estuary, Oregon. Gammarid amphipods, teleosts, and ghost shrimp were the most important food items of the staghorn sculpin whereas barnacle cypris larvae, cancer crab megalops, and copepods were the main components of the shiner surfperch diet. Only large staghorn sculpins ate teleosts, whereas only the smaller ones ate isopods. This study supports literature reporting a change in sculpin diet with size. Staghorn sculpins ate larger prey if they were larger. Monophagous foraging by the shiner surfperch was found with cancer crab megalops and crab zoea. Adequate sample sizes for future studies were determined.

A GEOGRAPHI C STUDY OF THE CITY OF COOS BAY AND ITS HINTERLAND
Feichtinger, John Rudolph
Marine Biology
Geography
Hinterland
198 pages
The city of Coos Bay is a sea port located on the upper reaches of Coos Bay, mid-way on the Pacific Coast of the State of Oregon. With a valuable virgin timber supply which stretches east of it across the Coast Range to the vicinity of Roseburg, and with a thriving, though small, dairy industry which focuses on the city, the people of the city have attempted to rival Portland and Astoria as sea ports. And, t0 live up to their self-imposed title of "the largest lumber port in the world".
A certain civic pride, and pride in achievement, are commendable and accepted in our modern society, but it is also possible to strain the limits of propriety. There is a desirability in "bigness" where size lends itself more effectively to efficient operation. But, the writer does not believe that extensive development is to be overly-encouraged where it is primarily dependent upon a single crop or industry. A false sense of security through large size alone is as -much a psychological boobytrap as is an overly pessimistic attitude. Both, or either, can lead to a misplaced reliance on emotional rather than factual data.

When I first arrived in the Hawaiian Islands on a teaching assignment in 1970 I naively expected to be greeted by a landscape clothed in the native flora. Instead, what I saw as I left the airport was a collage of introduced species which I took to be natives. It was not long before I realized the error (interestingly , one of the first courses I was to teach was entitled "Plants and Animals of Hawaii'', a little surprise for the man fresh off the boat.) Curiously, I had to travel 2,300 miles from my native California to be made aware of something that had so blatantly surrounded me all my life: that human habitations tend to assemble communities of exotic organisms. One look at any neighborhood garden with its many ornamentals should confirm this.

HAUL-OUT AREA USEAGE BY HARBOR SEALS (PHOCA VITULINA) AT THE NORTH COVE OF CAPE ARAGO, OREGON

Harbor Seals
Marine Biology
35 pages
Harbor seals were observed on 70 occasions from 7 April to 10 August, 2001, at the North Cove, Cape Arago, Oregon, to determine if the harbor seals used different haulout zones within the haul-out area during different life history stages. This study identified sex and age as the most important factors influencing the selection of haul-out zones. A haul-out pattern was observed on days when both low tides occurred during daylight hours: the number of animals hauled-out during a morning low tide was fewer than those during the afternoon low tide regardless of weather conditions.

Over the past 250 years, the composition of Earth's atmosphere has changed as a result of anthropogenic emissions of greenhouse gases. For example, activities such as deforestation, agriculture, and the burning of fossil fuels have produced a 31% increase in the concentration of atmospheric carbon dioxide ([CO2]) since 1750 (IPCC 2001). Earth's atmosphere is linked to the oceans at the sea surface, such that alterations in atmospheric composition are reflected in the water. In particular, atmospheric CO2 exists in equilibrium with dissolved CO2 (CO2(aq)) in the oceans. As the atmospheric [CO2] increases, gas exchange with the oceans causes a concomitant increase in [CO2(aq)], with concentrations rising toward a new equilibrium value (Goudriaan 1993, Guinotte and Fabry 2008).
