Patterns Of Genetic Structure In The American Kestrel (Falco Sparverius): Influence Of Distance And Migration And Implications For Monitoring And Management, Michaela Brinkmeyer
Patterns Of Genetic Structure In The American Kestrel (Falco Sparverius): Influence Of Distance And Migration And Implications For Monitoring And Management, Michaela Brinkmeyer
Boise State University Theses and Dissertations
Genetic structure is useful for inferring patterns of selection, gene flow and connectivity, and can define management units that aid in interpretation of spatially-specific trends and species management. American kestrels (Falco sparverius) are a widespread, generalist species with fully migratory, partial migrant, and resident populations. In many parts of their range, kestrels show evidence of declining population trends; however, it has been difficult to identify threats to kestrels because of differences in regional trends. We used a genome-wide sequencing approach to investigate the genetic structure of American kestrels, test hypotheses about the processes that influence genetic structuring of …
Dynamics Of Fat And Lean Mass In Refuelling Migrant Passerines Measured Using Quantitative Magnetic Resonance, Lisa V. Kennedy
Dynamics Of Fat And Lean Mass In Refuelling Migrant Passerines Measured Using Quantitative Magnetic Resonance, Lisa V. Kennedy
Electronic Thesis and Dissertation Repository
Although fat deposition during stopover in migrating passerine birds has been extensively studied, changes in lean mass during refuelling are not well understood. I used quantitative magnetic resonance (QMR) analysis to measure the deposition of fat and lean mass for both recaptured and single capture migrant passerines in spring and fall at Long Point, Ontario. Both the recapture analysis and single capture regression analysis indicated a substantial contribution of lean mass to overall increases in total body mass. Some of the variation in the relative deposition of fat and lean mass was explained by sex, age and season. I then …
The Winter Ecology Of The Piping Plover (Charadrius Melodus) In Coastal Georgia, Brandon Lennon Noel
The Winter Ecology Of The Piping Plover (Charadrius Melodus) In Coastal Georgia, Brandon Lennon Noel
Electronic Theses and Dissertations
Author's abstract: The Piping Plover (Charadrius melodus) is a federally listed species with three distinct breeding populations, including Great Plains (threatened), Great Lakes (endangered), and Atlantic Coast (threatened), all of which winter along the Atlnatic and Gulf coasts of the United States. I studied the winter ecology of the Piping Plovers on Little St. Simons Island (LSSI), Georgia, from 2003-2006, with emphasis on the conservation significance of this site for the endangered Great Lakes population. During 2003-2004 and 2004-2005, LSSI supported up to 100 Piping Plovers during peak migration, and approximately 40 birds wintered at this site. All populations had …
