An Assessment Of Trap Efficiency To Estimate Coho Salmon Smolt Abundance In A Small Alaskan Stream, Anthony Alexander Eskelin

Fisheries

Smolt abundance is commonly estimated using trap efficiency-based methods; however, few studies have investigated the accuracy of trap efficiency estimates. The objectives of this study were to: (1) test the hypotheses that (i) trap efficiency is not affected by release timing nor release distance, (ii) trap efficiency-based estimates of smolt abundance are concordant with smolt-adult mark-recapture estimates, and (2) evaluate if water level and turbidity influence trap efficiency. In Deep Creek, Alaska, during 2001 and 2002, coho salmon Oncorhynchus kisutch smolt abundance was estimated using trap efficiency-based methods and compared to independent smolt-adult mark-recapture estimates. Marked smolts were released at …

Freezing Tolerance And Survival Experiments With Various Intertidal Organisms From Kachemak Bay, Alaska, Heather Kristine Patterson

Marine Biology

Intertidal organisms at high latitudes experience multiple stresses created by freezing, including ischemia, free water reduction, and distortion and destruction of cells, and in response have adapted behavioral and physiological solutions. This study examined the response of intertidal organisms in Kachemak Bay, Alaska to freezing through laboratory experiments and field studies. Mytilus trossulus, Balanus glandula, Protothaca staminea and various limpets (Lottidae) survived freezing conditions to -10 and -20°C, depending on the season. Mytilus trossulus and B. glandula survived multiple freeze events at -10°C. Seasonal freeze response was not induced by exposure to low air temperature in M trossulus. Exposure to …

The E!Ect Of Trap Spacing On The Capture Of Brown Tree Snakes On Guam, Richard M. Engeman, Michael A. Linnell

United States Department of Agriculture Wildlife Services: Staff Publications

Trapping is central to the integrated control program to deter brown tree snakes from entering the outbound cargo 1ow from Guam. Trapping brown tree snakes is effective, but labor intensive. Increasing inter-trap spacings without loss of e3cacy could substantially increase the e3ciency of efforts to prevent dispersal of this species. Inter-trap spacings of 20, 30 and 40 m along perimeter trap lines were compared using recaptures of tagged brown tree snakes. No differences were found among the different spacing distances for the distribution of recapture times. The results indicate that for some situations, snake trapping may be extended or made …

Growth And Nutritional Development Of Reindeer (Rangifer Tarandus) And Muskoxen (Ovibos Moschatus), Katrina K. Knott

Biological Sciences

Young ruminants must grow and develop digestive function during brief summers in the Arctic. I examined growth and development of nutritional organs in reindeer and muskoxen as neonates (1 d), during transition from milk to forage (30-60 d) and at maturity. Reindeer and muskoxen gave birth to relatively smaller offspring than ruminants from more temperate regions. Costs of small birth mass are likely offset in neonates by an increase of thyroid hormones to enhance thermogenesis and hepatic reserves that provide additional nutrients during early development. Body mass gains during the neonatal period (1-30 d) were associated with well-developed abomasa that …

Frances Anne Hopkins And The George Back Connection: Tracking Through The Canadian Landscapes Of Two Nineteenth-Century Artists To Find Where Lines Converge, Pamela K. Macdonald

Arctic and Northern Studies

My paper examines the artistic influence of the renowned British explorer and artist George Back on fellow Rupert's Land artist Frances Anne Hopkins, wife of Edward Hopkins, the man in charge of the Montreal Division of the Hudson's Bay Company in the mid-nineteenth century. The aesthetic gap between the two artists is wide in that Back's sketches depict a kind of terrifying wasteland quality best described as sublime. Hopkins' Canadian landscapes are colorful, on the other hand, and show people who are at ease with their surroundings. Other notable artists also documented nineteenth-century Canadian landscapes in visual images and may …

Movement Of The Giant Red Sea Cucumber Parastichopus Californicus In Southeastern Alaska, Kristin Cieciel

Fisheries

This thesis provides information on sea cucumber movement that could inform management of the growing fishery for the sea cucumber, Parastichopus californicus, in Southeast Alaska. Daily movement of individual P. californicus was quantified at six sites to assess spatial variation in movement, at three-month intervals over one year at one site to assess seasonal changes in movement, and densities were measured monthly at three depths over one year. Movements varied among seasons and sites ranging from 0 to 34.5 m·24 h⁻¹, and were highest in summer (mean ± SE = 4.6 ± 0.5 m) and lowest in fall (mean ± …

Bovine Tuberculosis In Michigan White-Tailed Deer

Zoonotics and Wildlife Disease: Publications

Starting in 1995 hunter harvested, road killed, and other dead deer were examined for bovine TB infection. White-tailed deer in Michigan have since been tested year round for bovine TB. Testing revealed that most of the TB positive animals were located in a core area in the northeastern part of Michigan's Lower Peninsula. The core area is located around the four corners where the counties of Montmorency, Alpena, Oscoda and Alcona meet. Antrim, Crawford, Emmet, Iosco, Mecosta, Osceola, Otsego, Presque Isle, and Roscommon Counties have also had animals test positive for bovine TB.

In the U.S. today, the threat of …

Earth Sciences

An extensive set of carbonyl sulfide (OCS) and carbon disulfide (CS₂) observations were made as part of the NASA Transport and Chemical Evolution over the Pacific (TRACE-P) project, which took place in the early spring 2001. TRACE-P sampling focused on the western Pacific region but in total included the geographic region 110°E to 290°E longitude, 5°N to 50°N latitude, and 0–12 km altitude. Substantial OCS and CS₂ enhancements were observed for a great many air masses of Chinese and Japanese origin during TRACE-P. Over the western Pacific, mean mixing ratios of long-lived OCS and shorter-lived CS_{2 …}

Esophageal Muscle Physiology And Morphogenesis Require Assembly Of A Collagen Xix-Rich Basement Membrane Zone., Hideaki Sumiyoshi, Niv Mor, Sui Y Lee, Stephen Doty, Scott Henderson, Shizuko Tanaka, Hidekatsu Yoshioka, Satish Rattan, Francesco Ramirez

Department of Medicine Faculty Papers

Collagen XIX is an extremely rare extracellular matrix component that localizes to basement membrane zones and is transiently expressed by differentiating muscle cells. Characterization of mice harboring null and structural mutations of the collagen XIX (Col19a1) gene has revealed the critical contribution of this matrix protein to muscle physiology and differentiation. The phenotype includes smooth muscle motor dysfunction and hypertensive sphincter resulting from impaired swallowing-induced, nitric oxide-dependent relaxation of the sphincteric muscle. Muscle dysfunction was correlated with a disorganized matrix and a normal complement of enteric neurons and interstitial cells of Cajal. Mice without collagen XIX exhibit an additional defect, …

Steady-State Performance Of Wide Parabolic-Shaped Slider Bearings With A Couple Stress Fluid, Jaw-Ren Lin, Yu-Ming Lu

Journal of Marine Science and Technology–Taiwan

According to the Stokes micro-continuum theory, the effects of couple stresses upon the steady-state performance of wide parabolicshaped slider bearings are presented in this paper. To account for the couple stress effects arising from a Newtonian lubricant blended with various additives, the modified non-Newtonian Reynolds-type equation is derived using the Stokes motion equations together with the continuity equation. Comparing with the traditional Newtonianlubricant case, the effects of couple stresses characterized by the couple stress parameter signify an improvement in the steady-state performance. Increasing values of the couple stress parameter increases the bearing load-carrying capacity and reduces the required volume flow …

Membrane Lipid Biosynthesis In Chlamydomonas Reinhardtii: Expression And Characterization Of Ctp:Phosphoethanolamine Cytidylyltransferase, Wenyu Yang, Catherine B. Mason, Steve V. Pollock, Tracey Lavezzi, James V. Moroney, Thomas S. Moore

Faculty Publications

CTP:phosphoethanolamine cytidylyltransferase (ECT) is considered to be the regulatory enzyme in the CDP-ethanolamine pathway of phosphatidylethanolamine (PE) biosynthesis. The ECT cDNA of Chlamydomonas reinhardtii encodes a protein of 443 amino acid residues, which is longer than the same protein in yeast, rat or human. The translated product of cloned cDNA was expressed as a fusion protein in Escherichia coli, and was shown to have ECT activity. The deduced amino acid sequence has 41% identity with that of human or rat, and 30% with yeast. The ECT protein has a repetitive internal sequence in its N-and C-terminal halves and a signature …

Development Of A Safe Neutralization Assay For Sars-Cov And Characterization Of S-Glycoprotein, Dong P. Han, Hyung G. Kim, Young B. Kim, Michael W. Cho

Faculty Scholarship

The etiological agent of severe acute respiratory syndrome (SARS) has been identified as a novel coronavirus SARS-CoV. Similar to other coronaviruses, spike (S)-glycoprotein of the virus interacts with a cellular receptor and mediates membrane fusion to allow viral entry into susceptible target cells. Accordingly, S-protein plays an important role in virus infection cycle and is the primary target of neutralizing antibodies. To begin to understand its biochemical and immunological properties, we expressed both full-length and ectodomain of the protein in various primate cells. Our results show that the protein has an electrophoretic mobility of about 160–170 kDa. The protein is …

Owning Music: From Publisher's Privilege To Composer's Copyright, Michael W. Carroll

ExpressO

More than four years after Napster demonstrated the power of the Internet as a means of distributing music, we still are in the midst of a cultural and legal debate about what the respective rights of music copyright owners, follow-on creators, disseminators, and purchasers should be. A common assumption underlying much of the debate is that whatever settlement emerges, it will apply equally to all forms of expression. This Article questions that assumption by investigating the early history of copyright in music.

For the first time in legal scholarship, the Article reveals and examines the distinct early history of copyright …

BACKGROUND: Establishing genomic resources for closely related species will provide comparative insights that are crucial for understanding diversity and variability at multiple levels of biological organization. We developed ESTs for Mexican axolotl (Ambystoma mexicanum) and Eastern tiger salamander (A. tigrinum tigrinum), species with deep and diverse research histories.

RESULTS: Approximately 40,000 quality cDNA sequences were isolated for these species from various tissues, including regenerating limb and tail. These sequences and an existing set of 16,030 cDNA sequences for A. mexicanum were processed to yield 35,413 and 20,599 high quality ESTs for A. mexicanum and A. t. tigrinum, respectively. Because the …

Genetic Correlation Of Ram Sexual Performance With Ewe Reproductive Traits Of Four Sheep Breeds, G. Snowder, J. N. Stellflug, L. Dale Van Vleck

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Rams express differences in sexual performance during the breeding season. Breeding rams with high sexual performance scores as measured during a sexual performance test can improve flock fertility. Whether selecting rams for high sexual performance score will indirectly improve ewe reproductive performance is not known. The objective of this study was to estimate the genetic correlation between sexual performance scores of rams and reproduction of ewes. Sexual performance scores of rams and reproductive performance (number of lambs born per ewe exposed and number of lambs weaned per ewe exposed) from four breeds were analyzed with univariate and bivariate animal models …

Pinyon Jays Use Transitive Inference To Predict Social Dominance, Guillermo Paz-Y-Miño C, Alan B. Bond, Alan Kamil, Russell P. Balda

Papers in Behavior in Biological Sciences

Living in large, stable social groups is often considered to favor the evolution of enhanced cognitive abilities, such as recognizing group members, tracking their social status and inferring relationships among them. An individual’s place in the social order can be learned through direct interactions with others, but conflicts can be time-consuming and even injurious. Because the number of possible pairwise interactions increases rapidly with group size, members of large social groups will benefit if they can make judgments about relationships on the basis of indirect evidence. Transitive reasoning should therefore be particularly important for social individuals, allowing assessment of relationships …

Disabling Surveillance: Bacterial Type Iii Secretion System Effectors That Suppress Innate Immunity, Avelina Espinosa, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

Many Gram-negative bacterial pathogens of plants and animals are dependent on a type III protein secretion system (TTSS). TTSSs translocate effector proteins into host cells and are capable of modifying signal transduction pathways. The innate immune system of eukaryotes detects the presence of pathogens using specific pathogen recognition receptors (PRRs). Plant PRRs include the FLS2 receptor kinase and resistance proteins. Animal PRRs include Tolllike receptors and nucleotide-binding oligomerization domain proteins. PRRs initiate signal transduction pathways that include mitogen-activated protein kinase (MAPK) cascades that activate defencerelated transcription factors. This results in induction of proinflammatory cytokines in animals, and hallmarks of defence …
