Mammalian habitat use along a residential development gradient in northern Colorado
… Colorado. Multiple-season species occupancy and relative activity (frequency of detections) were measured in summer and winter seasons and these data were analyzed in conjunction with a novel, acoustic-based approach to assessing human activity. Impacts of exurban housing varied by mammal …

Construction of inducible expression systems for controlled transfer of Agrobacterium tumefaciens T-DNA in plant transient expression systems /
… study provided detailed information about the relative activity and regulation of several IPTG and cumic acid inducible promoters in A. tumefaciens. Additionally, new efficient cumic acid inducible promoters were constructed. Also, several A. tumefaciens toxins were identified from putative TA …

Assessing the relationships between pollinator-friendly plantings and birds, bats and white-tailed deer on farms in the Coastal Plain of Virginia and Maryland
… disservices, of pollinator-friendly plantings relative to wildlife, such as resident, migratory, and nesting birds (e.g., wild turkey (Meleagris gallopavo)), resident and migratory bats, and white-tailed deer (Odocoileus virginianus) are of interest to both landowners and conservation managers. …

An investigation of genetic factors impacting sterol profiles in Australian olive oils
… observed that sterol profiles appear to remain relatively consistent within individual cultivars, strongly implicating genetic factors as the cause of these different levels. The plant sterol biosynthetic pathway contains a bifurcation that leads to the formation of β-sitosterol or campesterol, …

Organization types and their business activities on the Internet
… The higher the grade the greater the increase in relative activity over time and the greater the promise for the organization type/business activity in terms of being a pointer for establishing a successful Internet presence. Due to the period limitation the thesis surveyed, further study could be …

Assessing the Long-term Impacts of White-nose Syndrome on Bat Communities Using Acoustic Surveys at Fort Drum Military Installation
… understand. The significance of these changes, relative to bat activity, may be based on the species-specific susceptibility to WNS. We used data collected from Fort Drum Military Installation, New York from the summers of 2003-2017 to analyze the accuracy of acoustic software programs, and …

The impact of edge-effects on aerial insectivorous bat assemblages in the Amazon
… cubic) were used to assess the changes in the relative activity of both forest specialist and open/edge forager species in response to edge effects, as well as changes observed at the assemblage level. Responses were assessed for seven individual species, two of which demonstrated a response to …

Temporal and spatial contextual modulation of walking direction in biological motion
… how the brain encodes walking direction remains relatively unexplored. The present thesis investigates the effects of temporal and spatial context on perceived walking direction, employing biological patterns of motion – point light animations. Chapter 2 uses an adaptation technique to …

Bioenergetic and Metabolic Signatures of Maternal Overnutrition in the Offspring Heart
… a murine model of diet-induced maternal obesity, relative activity and expression of electron transfer system (ETS) complex I was enhanced. This was accompanied by increased glycolytic gene expression. Neither cardiac mitochondrial substrate preference nor total respiratory capacity was altered in …
