Evaluation of Brook Trout (Salvelinus fontinalis) Introductions and Re-introductions Into Four Virginia Blue Ridge Mountain Streams

Isel, Michael, III 08 December 2011 (has links)
Approximately 100 brook trout were transplanted into each of four Virginia streams in September 2008. Garth Run and Kinsey Run were re-introductions, and Wildcat Hollow and Sweet Run were new introductions. Single pass electrofishing (EF) surveys were conducted with a backpack electrofisher five times during the study. Selected trout > 70 mm but < 100 mm and all trout > 100 mm received a Biomark® 134.2 kHz passive integrated transponder (PIT) tag to identify individual fish upon recapture. Trout were present in all streams almost three years post introductions. Catches decreased across the first four surveys. Young of year catch rates severely decreased from June 2009 (n = 77) to June 2010 (n = 7). Adult refuge under low flow conditions and environmental factors such as elevated stream temperatures and drought were determined to be potential limiting factors of brook trout success. Future monitoring is needed to further assess the populations.

Efforts Towards the Cross Coupling of Acylsilanes and Electrophiles via a Metal-Catalyzed Brook Rearrangement

Heusser, Carolyn Andrea January 2013 (has links)
Thesis advisor: Jeffrey A. Byers / Chapter 1: There are a limited number of examples of metal-catalyzed Brook rearrangements in the literature, none of which involve ruthenium, rhodium, or iridium which are common ketone hydrogenation catalysts. The content of this chapter introduces the traditional Brook rearrangement and its advantages and disadvantages in chemical synthesis. Furthermore, the few examples of metal-catalyzed Brook rearrangements of acylsilanes and structurally similar moieties are discussed. Chapter 2: Utilizing a Brook rearrangement under hydrogenation or transfer hydrogenation conditions opens up a new area of catalytic reactivity that has not been fully explored. To our knowledge, metal complexes based on ruthenium and rhodium have never been shown to catalyze a Brook rearrangement of acylsilanes. This chapter describes the mechanistic implications of a Brook rearrangement under hydrogenation or transfer hydrogenation conditions as well as the first example of a ruthenium-catalyzed Brook rearrangement of aryl acylsilanes. Chapter 3: Pioneering work performed by Jeffrey Johnson and co-workers in the area of catalytic coupling of acylsilanes and various electrophiles showed that formation of new C-C bonds through a Brook rearrangement can be a powerful synthetic tool. In this chapter, we investigate an intermolecular coupling of aryl acylsilanes and aldehydes through a metal-catalyzed Brook rearrangement under transfer hydrogenation conditions to yield two synthetically useful motifs, specifically oxygenated bicyclic compounds. A reaction screen was performed on the coupling capabilities of these two species with various ruthenium and rhodium catalysts. The result of the screen was synthesis of a silyl ether acetal through employing the starting material as the reducing equivalent. Additionally, mechanistic insight was gained to further develop the proposed methodology. Chapter 4: An intramolecular approach to achieving coupling of acylsilanes and many different types of electrophiles was envisioned as a way of furnishing synthetically useful bicyclic compounds in one step. The focus of this chapter is the synthesis of a novel acylsilane that we proposed could undergo an intramolecular cross coupling reaction under transfer hydrogenation conditions. The conclusion of this chapter outlines the future direction of the project, which entails a new route to an intermolecular cross coupling of acylsilanes and various electrophiles. Published work from Michael Krische's laboratory helped us envision a different type of acylsilane, specifically an α,β-unsaturated acylsilane, in which binding to a metal center would proceed through a π-allyl intermediate. Ongoing efforts in the coupling of α,β-unsaturated acylsilanes with electrophiles are currently underway. / Thesis (MS) — Boston College, 2013. / Submitted to: Boston College.
