Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz Mar 2018

Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz

Student Research and Creative Activity Fair

Abstract:

The northern long-eared bat (Myotis septentrionalis) is one of many species of hibernating bats in North America affected by a recently discovered fungal disease called white-nose syndrome (WNS). Northern long-eared bats seem to be extremely susceptible to the disease with mass fatalities occurring among populations in eastern North America. Researchers in the eastern distribution of this species have performed mtDNA analysis to identify the population structure of the species; however, genetic analysis has yet to be done in western parts of its distribution. The goal of this study is to create a better understanding of the genetic makeup of ...

Estrogenic Effects On A Protandrous Hermaphroditic Species: Amphiprion Percula, Randall Burns, Katie Dose Apr 2014

Estrogenic Effects On A Protandrous Hermaphroditic Species: Amphiprion Percula, Randall Burns, Katie Dose

Undergraduate Research Symposium

Estrogen concentrations are increased in aquatic environments due to the addition of pharmaceutical drugs (i.e. birth control) through runoff water. This manipulates maturation of sexes within many species that inhabit aquatic enviornments, including fresh and marine habitats. Amphiprion percula exhibit a hierarchal system behavioral pattern, which determines the social status of individuals within a group. Multiple clown anemonefish, A. percula were studied via a controlled environment and hierarchal succession was observed under estrogenic additions. From this study, data on sex change of a hermaphroditic protandrous species was observed under the influence of three concentrations of natural estrogen. Based on ...


Ubiquitylation Of Proteins In The Frozen Wood Frog, Alexa Khan, Michael Ulrich, Kenneth Storey, Frank Van Breukelen Aug 2011

Ubiquitylation Of Proteins In The Frozen Wood Frog, Alexa Khan, Michael Ulrich, Kenneth Storey, Frank Van Breukelen

Undergraduate Research Opportunities Program (UROP)

Wood frogs (Rana sylvatica) are able to withstand freezing. Respiratory and cardiac activity ceases when frozen. Homeostatic functions like protein synthesis and degradation presumably must also be compromised. We investigated the fate of ubiquitin-dependent proteolysis in the freeze-thaw cycle and how that might gives clues to wood frog survival. We performed western blots for ubiquitin conjugates


The Role Of An Abc Transporter As A Steroid Antagonist In Drosophila, Gregory King, Andrew Andres Aug 2011

The Role Of An Abc Transporter As A Steroid Antagonist In Drosophila, Gregory King, Andrew Andres

Undergraduate Research Opportunities Program (UROP)

Drosophila melanogaster are holometabolous insects that have several distinct life stages including larvae and a winged adult. The larval stage is mainly a time of feeding and growth, while the adult stage is optimized for sexual reproduction and dissemination. The larval stage can itself be divided into three time periods, or instars: 1st (L1), 2nd (L2), and 3rd (L3) (Figure 1). Larval growth – both between instars and beyond – depends on specific signaling pathways controlled by a cholesterol derived steroid, 20-hydroxyecdysone (20E). Although 20E is a systemic developmental signal, little is known about the molecular details of how different tissues respond ...


Accumulation Of Polonium-210 In Different Species Of Fish In Lake Mead, Suraj Ghevarghese John, Shungmugam Nallaperumal, Vernon Hodge Apr 2011

Accumulation Of Polonium-210 In Different Species Of Fish In Lake Mead, Suraj Ghevarghese John, Shungmugam Nallaperumal, Vernon Hodge

Festival of Communities: UG Symposium (Posters)

Discovered by Pierre Curie and Marie Skłodowska-Curie in 1898, polonium is a chemical element with an atomic number of 84. This rare naturally occurring radioactive element is chemically similar to bismuth and tellurium, and forms in uranium ores. Polonium-210 is an naturally occurring radioactive element with a half-life of 138.376 days(1). This element is found in trace amounts in most organisms. Our research is focused on the accumulation of polonium-210 in fish that occupy in Lake Mead.

The sample species is chosen based on varying lake stratification (layers of the lake). This gives us a good idea of ...


Effect Of Temperature And Oxygen Levels On Lactate Production In Palaemonetes Pugio, Robin Schofield, Teresa Mika, Carl Reiber Apr 2011

Effect Of Temperature And Oxygen Levels On Lactate Production In Palaemonetes Pugio, Robin Schofield, Teresa Mika, Carl Reiber

Festival of Communities: UG Symposium (Posters)

Oxygen delivery rates must keep pace with the increased metabolic rate observed in poikilothermic animals exposed to increased temperature if aerobic metabolism is to be maintained. Physical failure of the oxygen delivery system to meet these demands may be a mechanism of cardiac failure in crustaceans at temperature extremes. As part of the determination of the effect of temperature on the cardio-respiratory system, we are measuring whole animal lactate levels in grass shrimp acclimated to 20°C over temperature ranges in normoxic and hyperoxic conditions. Lactate levels are measured as an indicator of a switch from aerobic to anaerobic metabolism ...
