Combined effects of water chemistry, canopy cover, and stream size on benthic macroinvertebrates along a Central Appalachian stream continuum
… these components to determine if localized variation in alkalinity and canopy cover would modify stream continuum predictions. Localized variation in alkalinity and canopy cover significantly affected macroinvertebrate structure and function and modified stream continuum predictions. Results …

Aggregate potential of Irish south coast offshore palaeovalleys
… of the seabed and the processes that cause large scale variation to the morphology and sedimentology is crucial in determining marine aggregate resource potential on the south coast. Qualitative data was processed using a multiproxy geophysical and sedimentological approach, creating detailed …

Characterization and analysis of process variability in deeply-scaled MOSFETs
… and decomposition approaches to quantify variation and its sources are explored. Two examples of transistor variability characterization are discussed: contact plug resistance variation within the context of a transistor, and AC, or short time-scale, variation in transistors. Results show …

Environmental DNA (eDNA) Metabarcoding: Analysis of Freshwater Macroinvertebrate Community Structure and Diversity
… provided by eDNA metabarcoding can detect fine-scale variation at a local scale, suggesting that this method is a promising molecular technique for surveying freshwater macroinvertebrate biodiversity.</p>

Evaluating heat mitigation by urban canopy in New York City’s public housing developments
… urban parks to look at intra-city temperature variation and the temperature reductions provided by much smaller, fragmented tracts of urban canopy present in public housing developments</p> <p>We leverage land surface temperature measurements from NASA’s ECOSTRESS sensor, combined with high …

Studies of Lagrangian modeling techniques with applications to deep ocean carbon sequestration
… due to complications in specifying the subgrid scale variation of isopycnal slope and diffusivity in steeply sloped or convectively unstable regions, and in accurately implementing the Gent-McWilliams eddy-induced transport.

Translators as Scribes--A Comparison of Scribal Practice and Translation Practice: Exodus 1-14 in the Hebrew Manuscript Tradition and the Old Greek
… and translation. Finally, I consider "large-scale" variation in the Ten Plagues narrative, analyzing a much discussed pattern of insertions found in 4QpaleoExodm and the Samaritan Pentateuch. Nothing comparable can be found in the Septuagint, showing that the translator, in this case, was …

Downstream change in channel hydraulics along the River Severn, UK
… the mechanisms which control the catchment-scale variation of channel stability, sediment transport and siltation, flood generation and aquatic habitats. However, little attention has been given to quantifying the detailed spatial and temporal variability of channel hydraulic parameters, …

Clustering and visualizing solution variation in massive programming classes
… approach, and readability. Understanding large-scale variation in solutions is a hard but important problem. For teachers, this variation could be a source of innovative new student solutions and instructive examples. Understanding solution variation could help teachers write better feedback, …

Micro scale heterogeneity of spiders (Arachnida: Araneae) in the Soutpanberg, South Africa: a comparative survey and iventory in representative habitats
Coarse-scale studies that focus on species distributions and richness neglect heterogeneity that may be present at finer scales. Studies of arthropod assemblage structure at fine (1 x 1 km) scales are rare, but important, because these are the spatial level at which real world applications are …

Cities for birds, birds for cities: The urban ecology of birds across scales from global sampling to individual responses
… examines the urban ecology of birds across scales, from a global standardized monitoring framework to city-level drivers of species prevalence and individual behavioural responses to human activity in an urban songbird. In Chapter 2, I describe and validate the Global Urban Bird Survey, a …

Shallow sea tidal friction and sediment transport
… radar image of the Southern Bight showed grey-scale variation strongly related to the bottom topography, with increased brightness on the western flank of the sandbanks and sand waves of the region. A tidal surface velocity field was generated, for the time of the image, by reference to the …

Development of computational approaches for whole-genome sequence variation and deep phenotyping
… frameworks to store and analyse population scale variation data. Based on the evaluation, I implement a variant analysis platform that incrementally merges samples, annotates variants and enables the analysis of 10,000 individuals in minutes. An incremental design for variant merging and …

The spatial scale of adaptive population differentiation in Atlantic Salmon: local adaptation in smolt migration timing
… salmon. Specifically, it aims to examine variation in the timing of smolt migration among independent tributaries of single river systems and to screen individual fish for molecular genetic variation at neutral microsatellite loci. Through integration of distinct yet complimentary …

Towards an integrated model for assessing the effects of changes in climate and land use patterns on the quantity and variability of river flows in Indonesia
… under IPCC SRES GHG emission scenarios and downscaled GCM patterns. The land use patterns are translated into a set of hydrological parameters and, together with the climate variables, are used for calculating the monthly discharge on a cell-by-cell basis. The runoff is totalled from all cells …
