Structure of an Ensemble of Insectivorous Bats
… characteristics that may permit resource partitioning but few studies focus on more than one or two traits. Using seven sympatric Jamaican bats, I examined features which could allow for spatial, temporal, behavioural and dietary partitioning including wing morphology, echolocation …

Optimizations to a massively parallel database and support of a shared scan architecture
… and analysis. We tackle the challenge of partitioning the data across multiple nodes with many CPUs and GPUs by means of an indexing framework. We implement a QuadTree spatial partitioning scheme and demonstrate how it improves the latencies of many queries when using the index as opposed …

Toward Predictable and Efficient Deep Neural Network Inference on Graphics Processing Units
… SGPRS, a spatio–temporal scheduler that combines spatial partitioning with stream-based temporal concurrency and explicit staging for coarse preemption and partition reuse without costly reconfiguration. Second, we develop GRAIL, a lightweight online predictor of latency and throughput under …

Constraints on Neltumius arizonensis (Coleoptera: Bruchidae) as a biocontrol agent of prosopis in South Africa : the role of parasitoids
… the sampling period hence there is no temporal partitioning of resources. 4. Percentage emergence of N. arizonensis was low at the start of the season but increased as the season progressed with higher proportions of N. arizonensis emerging from 'tree' pods than 'ground' pods. Regardless of the …

Biotic and abiotic influences on aggressive interactions within larval <i> Ambystoma</i> assemblages
… species is often facilitated through temporal or spatial partitioning mechanisms that reduce or eliminate direct interaction. However, in many communities exhibiting guild structure, wherein potential competitors may also prey on one another, sympatric relationships persist despite species' …

Toward predictable execution of real-time workloads on modern GPUs
… cannot be trivially achieved in modern GPUs. New spatial and temporal scheduling policies need to be explored and enforced in modern GPUs to enable predictable execution of GPU tasks. Therefore, this thesis investigates two approaches to achieve predictable execution on NVIDIA GPUs. The first …

Regeneration Dynamics in Old -Growth and Second-Growth Southern Appalachian Cove Forests
… at the old-growth site, and evidence for the spatial partitioning of some tolerant species along a distance gradient from canopy gap centers was found to occur. The herbaceous community in the second-growth forest, including vernal species, had a higher density, species richness and diversity …

Resource selection and abundance estimation of moose: Implications for caribou recovery in a human altered landscape
… them to survive in nutrient-poor habitats spatially separated from other ungulates and their shared predators. The conversion of old-growth forests to young seral stands is hypothesized to increase the abundance of moose (Alces alces), the dominant prey for wolves (Canis lupus), resulting …

Trees, Birds, and People: Resource Use and Interspecific Interactions in a Namibian Cavity Nesting Guild
… explore potential instances of cavity resource partitioning. Use of nest cavities appears to sort out by size among both cavity-excavators and secondary cavity-nesters. Excavators appear to partition cavity substrate spatially by decay class, while spatial partitioning among secondary nesters …

Scattering of internal gravity waves
… thesis examines the high wavenumber scatter and spatial partitioning of wave energy at ‘rough’ topography containing features that are of similar scales to those characterising incident waves. The research presented here includes laboratory experiments using synthetic schlieren and PIV to …

Evaluating Competition Between Sympatric Flying Squirrels (Glaucomys Spp.) In Northeastern Minnesota
… 1: Climate change is causing unprecedented spatial overlap of previously allopatric species, which can lead to competition between species with similar niches. Northern flying squirrels (Glaucomys sabrinus) and southern flying squirrels (G. volans) have increasingly overlapping ranges due to …

Plant root contributions to the carbon balance of a changing agricultural Midwest
