Assessing The Effects Of Prescribed Fire On Foraging Bats At Mammoth Cave National Park After The Arrival Of White-Nose Syndrome, Rachael Elizabeth Griffitts
Assessing The Effects Of Prescribed Fire On Foraging Bats At Mammoth Cave National Park After The Arrival Of White-Nose Syndrome, Rachael Elizabeth Griffitts
Online Theses and Dissertations
Habitat use of bats may shift following population level impacts of White-nose Syndrome (WNS). Multiple bat species have experienced unprecedented population declines due to WNS, including federally listed Myotis sodalis (Indiana bat) and Myotis septentrionalis (northern long-eared bat). Specifically, the effect of WNS across forest landscapes is unclear in relation to prescribed fire. Mammoth Cave National Park (MACA) has employed a prescribed fire regime since 2002 and WNS was detected on MACA in 2013. Bat activity was monitored across burned and unburned sites at MACA before (2010-2012) and after the detection of WNS (2013-2016) using transects of acoustic detectors (Anabat …
Galápagos Sea Lion (Zalophus Wollekaeki) Play Behaviors On San Cristóbal Island, Ecuador, Mary Ann Kincer
Galápagos Sea Lion (Zalophus Wollekaeki) Play Behaviors On San Cristóbal Island, Ecuador, Mary Ann Kincer
Online Theses and Dissertations
My thesis concerns observations of play activities from videotapes of Galápagos sea lions on San Cristóbal Island from mid-summer of 2008. I begin with a discussion of ideas about play and types of play, elaborate the conceptual system of projects and routines in play, and provide a brief description of sea lion taxonomy and forms of play specific to Galápagos sea lions. Observing approximately 713 minutes of videotapes, I coded approximately 161.5 minutes of play projects and routines. Of the 713 minutes, 241 minutes were used in training, and 472 were coded independently by two coders for reliability. The two …
Factors Influencing Pre-Fledging Mass Recession Of Nestling Tree Swallows, Katrina Deann Reeda Moeller
Factors Influencing Pre-Fledging Mass Recession Of Nestling Tree Swallows, Katrina Deann Reeda Moeller
Online Theses and Dissertations
Fledglings of some aerial insectivores experience pre-fledgling mass recession, possibly to achieve an optimum wing loading by the time of fledging. However, studies of aerial insectivores to date have been limited to two species of swifts (Apodidae), and additional studies of species of aerial insectivores are needed to determine if factors contributing to pre-fledging mass recession vary among species. Thus, my objective was to examine factors contributing to pre-fledging mass recession by nestling Tree Swallows (Tachycineta bicolor). My study was conducted during the 2015 breeding season at the Blue Grass Army Depot in Madison County, Kentucky. Nestling Tree Swallows (n …
American Kestrels (Falco Sparverius) May Use Tail-Pumping To Maintain Balance, Joshua Suich
American Kestrels (Falco Sparverius) May Use Tail-Pumping To Maintain Balance, Joshua Suich
Online Theses and Dissertations
When perched, several species of small falcons, including American Kestrels (Falco sparverius), often pump their tails, but the possible function of this behavior is unknown. My objective was to use observations and experiments to examine the possible function(s) of tail-pumping by American Kestrels. Fieldwork was conducted from March 2015 to December 2015 at the Blue Grass Army Depot in Madison County, Kentucky. During observations of focal kestrels, I noted their behavior (e.g., landing on a perch, hunting, or consuming prey), including when and how often they pumped their tails (i.e., rapid movement of the tail down, then back up to …
Characteristics, Contexts, And Possible Functions Of The Vocalizations Of Blue Jays, Dustin Eric Brewer
Characteristics, Contexts, And Possible Functions Of The Vocalizations Of Blue Jays, Dustin Eric Brewer
Online Theses and Dissertations
Many species in the family Corvidae, including Blue Jays (Cyanocitta cristata), are known to have large vocal repertoires. However, perhaps due to its perceived complexity, few investigators have attempted to describe the vocal repertoire of Blue Jays. Therefore, my objectives were to describe the vocal repertoire of Blue Jays, determine the characteristics of their calls, and suggest possible functions. During 2015 and 2016, I studied free-living Blue Jays in and near Richmond, Madison County, Kentucky. I observed Blue Jays at 17 different locations, recorded their vocalizations, and noted the behavioral contexts during which calls were uttered. I also conducted playback …
