Spatial and predictive foraging models for gray bats in northwest Georgia and a comparison of two acoustical bat survey techniques
The federally endangered gray bat (Myotis grisescens) is an obligate, year-round, cavedwelling species. Efforts to protect caves occupied by gray bats have proved beneficial to recovery. Specific gray bat foraging area characteristics also are critical to gray bat population recovery and …

Fruit chemical traits shape bat nutritional ecology: from basic science to applications
… the impact of fruit secondary metabolites on the foraging behavior and digestive physiology of bats (Chapters 2-4) while applying insights from basic chemical ecology to inform forest regeneration strategies (Chapter 5). The studies were conducted in northeastern Costa Rica at La Selva Biological …

Role of bats as natural pest control agents of moth pests (false codling moth and carob moth) on citrus orchard
… the interest in services that insectivorous bats provide within agricultural landscapes through insect pest suppression has gained recognition globally. Multiple studies have thoroughly examined the vital role played by insectivorous bats within agricultural landscapes as biological control …

Bat activity over wetlands: temporal and spatial variation
<p>"Foraging animals face decisions about when and where to forage based, in part, on prey availability, which can fluctuate temporally as well as spatially. For temperate insectivorous bats, wetlands are important forage habitats because they provide water and high abundances of insects. My …

Biotic and abiotic mechanisms shaping multi-species interactions
… of Piper fruits among three frugivorous bats, illustrating the importance of fine-scale mechanisms that facilitate species coexistence and influence plant–animal interactions. In Chapter 3, I demonstrate how the chemical ecology of a Neotropical shrub, Piper sancti-felicis, shapes fruit …

Transcriptional effects of predator cues in the brain of Spodoptera frugiperda (lepidoptera: noctuidae) moths exposed to bat ultrasound
… tympanic organs for recognizing ultrasonic bat calls have evolved and facilitate the avoidance of predation via eliciting flight cessation or aerial maneuvers when stimulated by ultrasound. In this study, I exposed adult male fall armyworm (Spodoptera frugiperda) moths to recorded ultrasonic …

Bat Resource Utilization Along the Potomac River Corridor in Maryland
… use and population responses. The response of bats to periodical cicadas is largely unknown. Using a before-after-control-impact study design, we deployed ultrasonic acoustic detectors during the summers of 2020–2022 within and just outside the range of the cicada emergence along the Potomac …
