Spatial and Temporal Activity of Migratory Bats at Landscape Features
… of migrating bats although spatial and temporal activity may depend on species-specific migration strategies. I predicted that latitudinal migrating bats would have higher activity along north-south oriented linear landscape features, especially during late-seasonal migration periods, …

Anthropogenic effects on site use and temporal patterns of terrestrial mammals in Harenna Forest, Ethiopia
… occupancy (i.e., habitat use), detection, and temporal activity and overlap. I recorded 26 terrestrial and arboreal mammalian species and I had sufficient data to model occupancy for 13 species and temporal activity for 14 species. Occupancy and detection were generally higher for herbivores …

Comparing density analyses and carnivore ecology in Madagascar's southeastern rainforest
… that vary in forest disturbance, and 3) explore temporal activity patterns of rainforest carnivores. I found the spatially-explicit-capture-recapture models were empirically superior, as they are flexible and account for spatial variation in detection probability and area estimation. I found both …

A generative model for activations in functional MRI
Detection of brain activity and selectivity using functional magnetic resonance imaging (fMRI) provides unique insight into the underlying functional properties of the brain. We propose a generative model that jointly explains neural activation and temporal activity in an fMRI experiment. We derive …

Survey and Comparison of Amphibian Assemblages in Two Physiographic Regions of Northeast Tennessee.
… Tennessee, comparing species composition and activity. The first, Henderson Wetland, is in the Appalachian Ridge and Valley physiographic region. The second, John's Bog, is in the Blue Ridge. Survey methods included random walks, aural surveys, and point source collections during a 16-month …

Spatiotemporal memories in honey bees: microarray analysis of time-trained foragers
… bees have the ability to form distinct spatiotemporal memories that allow them to return repeatedly to different attractive food sources at different times of day. As a first step toward understanding the molecular basis of this striking flower fidelity, this study was designed to determine …

Hidden Influence in Dynamic Networks
… among networked Markov chains based on temporal activity patterns. Next, I quantitatively analyze the shifting geopolitical relationships and digital diplomacy efforts between two nation-states, employing a node representation learning strategy. Lastly, I apply a geometric deep learning …

Bat Habitat Ecology Using Remote Acoustical Detectors at the Army National Guard Maneuver Training Center - Fort Pickett, Blackstone, Virginia
… patterns, detection probabilities, spatial and temporal occupancy, and investigate species interactions. This thesis is broken down into three distinct chapters each intended to be a stand-alone document. The first establishes the basic ecology from natural history accounts, provides an overview …

Activities Within a Myotine Bat Community With Emphasis on the Endangered Indiana Bat, Myotis Sodalis
… habitat. M. sodalis showed the highest levels of activity and foraging events among the three species and had a significant main effect of habitat. Forest corridors had the highest levels of M. sodalis activity, although standing freshwater sources were most important for foraging during the …

Common Time: Music, Empathy, and a Politics of Care
… practice. Music, as a participatory and temporal activity facilitating social synchrony, can foster dialogic and reciprocal relations in social life. To systematise and study a participatory music activity on an organisational and community level, I designed and implemented two …

DAPK3 Suppresses Mammary Acini Morphogenesis and is Required for Mouse Development
… and that the Dapk3 promoter exhibits spatio-temporal activity in the developing heart and nervous system in addition to the gastrointestinal myenteric plexus of adult mice.</p><p>Importantly, our data suggests that DAPK3 is expressed in the breast epithelia of adult mice and that potential …

Über die Arc-catFISH-Methode als neues Werkzeug zur Charakterisierung der Geschmacksverarbeitung im Hirnstamm der Maus
… (cellular compartment analysis of temporal activity by fluorescent in situ hybridization), die die Charakterisierung der Antwort großer Neuronengruppen auf zwei Stimuli erlaubt, wurde zur Untersuchung geschmacksverarbeitender Zellen im NTS angewandt. Im Zuge dieses Projekts wurde …

Behavioural and Neuroimaging Studies of the Influence of Semantic Context on the Perception of Speech in Noise
… people. fMRI was then used to look at neural activity associated with deriving benefit from meaningful context. Whole-brain EPI data were acquired from young (16 participants, 19-26) adults using a sparse imaging design. Participants heard coherent and anomalous sentences in the scanner, and …

Exploiting spatial and spectral information for audio source separation and speaker diarization
… the environments, and to estimate the temporal activity of each source. The performance of the proposed methods is experimentally evaluated using different datasets, between simulated and live-recorded. The elaborated results show the superiority of the proposed methods over recently …

Abiotic and biotic determinants of tick-borne disease risk in Central Panama
… and humidity, and spatial abundance and temporal activity patterns vary among tick species and life stages. Abiotic variables influence off-host tick survival and may define the limits of a tick’s geographic range. However, successful completion of the life cycle is also governed by …

Arc expression in the parabrachial nucleus following taste stimulation
… Arc catFISH (cellular compartment analysis of temporal activity by fluorescent in situ hybridisation) method has been used in our lab to study neural activation following taste stimulation in the first central structure in the taste pathway, the nucleus of the solitary tract. This method uses …

Location-Based Social Media for Activity Space Modeling
Human activity research is rooted in the study of modeling the patterns of human activities in space and time. Previous studies have made prevalent progress in the theories, methods, and applications of human activity analysis. Among these studies, human activity space modeling has been a crucial …
