• Blood lead levels in Bald Eagles (Haliaeetus leucocephalus) in Southeast Alaska by gender and capture location.

      Hambleton, Jessica (2014-04)
      Research into the effects of lead on bald eagles has demonstrated that lead levels are higher in bald eagles than other birds at lower trophic levels (Burger and Gochfield 2009). Bald eagle survey data collected in Alaska also tells us that the breeding populations of Alaska contain a substantial proportion of the total number of eagles in North America (Hodges 2011). This project focused on the blood lead levels in previously tagged birds for which blood had been collected by the United States Fish and Wildlife Service. The samples included 32 individuals, with 17 males and 15 females. Males had a mean blood lead level of 0.0283±.0072 mg/L and females had a mean blood lead level of 0.0862 ±0.0866 mg/L (see figure 1). Statistical tests of blood lead level and gender, distance to Greens Creek Mine and distance to Juneau, Alaska all showed non-significance. Future studies focusing on individuals with known breeding areas as well as age class should be conducted.
    • Ecclystenoid Circulation in Chinoecetes Baird: And How Laboratory Holdings Effect Hormone Expression

      Deal, Cole (2017-07-15)
      Laboratory studies have been very important in understanding the physiology of commercially important crustaceans although removing crabs from their natural habitat can remove the crab from natural biological cues such as photoperiod, tidal cycles, and habitat. By assaying for circulating ecdysteroids in hemolymph of Dungeness crab, we can better understand how artificial settings are affecting the physiology of these crustaceans, in turn how they determine the outcome of laboratory studies by monitoring these differences between environments. The main goal of this project will be to determine whether there is a clear and present difference in ecdysteroid concentration between Tanner crab that have been exposed to lunar cycles; meaning they have tidal, temperature, depth and photoperiod influences, compared to lab setting Tanner crab, which will not have these external influences acting upon them.
    • Familia de Immigrantes: Finding Heritage on the Road

      Ainza, Rosie (2017-07-15)
      My URECA project has centered around creating a poetry collection inspired by finding heritage and cultural community through life on the road around Northern Mexico and the U.S. Southwest. My original objective was to highlight the shared hopes and fears of my own family and the people I meet while on the road. I aimed to pay close attention to resisting ethnographic elements within this project so that my research and writing may resist coloniality while imparting intersubjective reciprocity via the sharing of stories and experiences through a consanguineous journey.
    • Place Names as Evidence for Historic Resource and Property Rights Among the Tlingit: An Interactive Approach

      Sorum-Birk, Elise (2017-07-15)
      My goal was to create an interactive app of Tlingit place names in the Juneau area in order to use it as a tool for education and resource management. The secondary objective was to write an academic paper about the project and to present at the Alaska Native Studies Conference in Fairbanks.
    • Black Carbon / Juneau Icefield

      Nathlich, Abigail (2017-07-15)
      The original objective of my project was to look at how black carbon is quickening the melt rate of the Juneau Icefield as well as what the effects are on snow melt in urban and rural areas around Juneau. The hope for the results of this study are to see a visible representation of how quickly (or not quickly) the black carbon is melting the snowpack. It will be important to continue this study to look at how it is changing long term, but for now we are in the beginning stages of this study. We know that black carbon is effecting the icefield and the glaciers but this will help us to see what exactly it is effecting and how severe it is.
    • Killer Whale Ecotypes in the Juneau Area

      Luck, Emma (2017-07-15)
      The goal of this project was to identify the most common killer whale ecotype in the Juneau area. Over 400 photographs of killer whales taken from the years 2012-2015 were collected from Juneau photographers and marine naturalists on various whale watching boats. The photos were analyzed and the killer whales were identified as either resident, transient, or offshore based on morphological characteristics. Additionally, the individual whales were compared to published killer whale identification catalogs and identified when possible.
    • Investigation of Physiological Similarities Between Pandalus platycerus and Pandalus danae

      Bower, Esther (2017-07-15)
      The original project objective was to determine a suitable model organism to study Pandalus platyceros. I proposed to use the local dock shrimp Pandalus danae to do this research. This project allowed me to further my research on the study of Pandalid shrimps. I have been working with a very large species of shrimp for 3 years and getting experience working with a small shrimp species has greatly influenced my strengths in dissection methods. I feel confident I could isolate almost any tissue in any shrimp species given the correct tools, something I was skeptical about before this project. This project will give my mentor and I the opportunity to publish another gene sequence and further the knowledge of the genus Pandalus. In the future I could use this knowledge to sequence androgenic gland genes in other Pandalus species, potentially becoming part of a master’s project.
    • White Privilege: The Effects of Informer Race on Perceived Legitimacy

      Hawkins, Elizabeth (2017-07-15)
      The goal of this research was to investigate how the race of an informer of White privilege affects the perceived legitimacy and recognition of its existence through either a factual based (central route) or emotion based (peripheral route) message.
    • The Salinity Threshold of Market Squid Embryos in Southeast Alaska

      Sekerak, Vasily J. (University of Alaska Southeast, 2018-03-07)
      My initial project focused on the way market squid embryo morphology can possibly be effected by ocean salinity levels during development. This was to be accomplished by testing two sets of embryos with three replicates each. These two sets would comprise a salinity level that matched the ocean conditions of Sitka sound, and a comparative salinity which would represent the low salinity levels of the inner passages of Southeast Alaska. Once the embryos hatched they would be transferred into tanks especially designed to safely contain soft tissue organisms. After several weeks of paralarval development, the squid would then be euthanized in accordance with regulations and their statoliths would be removed and analyzed for and morphological differences. As it currently stands my project has achieved a working prototype of the circulatory current aquarium that I had originally proposed in the beginning. This aquarium system exists on larger scales, however I was able to draft, develop and test my own small scale version. This scaled down aquarium allows for larval stage vertebrates and invertebrates on a focused level that’s optimized for smaller labs.
    • Pilot investigation into the age structure of market squid, Doryteuthis opalescens, in the Gulf of Alaska

      Navarro, Michael; Wehde, Dawn (University of Alaska Southeast, 2018-03-08)
      The objective of my URECA funded project was to conduct a pilot investigation that aimed to provide a data set of the age, size, and maturity of market squid, Doryteuthis opalescens, collected in the Gulf of Alaska. The information I collected was used to infer the establishment of a residential or transient population of market squid in the sampled area. I hypothesized that squid collected offshore (> 100m from the shoreline) would be less sexually mature and younger than squid collected inshore which supports the establishment of a residential population. In comparison, no significant differences between size, maturity, and age between squid collected offshore and inshore supports that the squid are from a transient population.
    • Sayeik

      Holton, Luke (University of Alaska Southeast, 2018-09-02)
      The original purpose of this film project was to document the current sociopolitical attitude towards revitalization of Tlingit place names within Southeast Alaska. Several high-visibility name revitalizations (Utqiagvik, Denali, Tlux’satanjin, etc) have been facilitated by the Alaska Historical Commission in the previous years, and this film addresses the cultural impact that name revitalization might have on Alaska Native populations.
    • Colonialism's Legacy and the Traditional Strength to Heal

      Helgeson, Claire (University of Alaska Southeast, 2019-03-15)
      Colonialism's historical violence has legacies yet to be sufficiently acknowledged. The force of genocide is leveled against culture, language, knowledge, and even memory. Unacknowledged violence buries itself in the deepest parts of our souls resulting in a spiritual consumption...
