Changes in Patterns of Territory and Habitat Overlap in Wood-Warblers Over Evolutionary Time
… closely related species suggest that they should overlap in space and use similar habitats. However, ecological similarity may result in fitness costs when closely related species live together. Previous work on birds suggests that close relatives avoid each other by using different habitats. I …

The impact of White Shark (Carcharodon carcharias) sightings and attacks on recreational water use patterns in False Bay
… sharks. In this study I establish the extent of spatial overlap between white sharks and water users at two popular recreational beaches in False Bay (Fish Hoek and Muizenberg), and investigate how shark sightings (accompanied by warning flags and/or a siren) as well as attacks influence water …

TROPHIC ECOLOGY OF JUVENILE LEAN AND SISCOWET LAKE TROUT (SALVELINUS NAMAYCHUSH) FROM U.S. WATERS OF LAKE SUPERIOR
<p>In this study, I investigated the spatial overlap, diet similarity, and isotopic niches of juvenile Lean and Siscowet Lake Trout ecotypes across six ecoregions of Lake Superior. Spatially, Lean and Siscowet were observed in overlapping depth distributions. Leans were most abundant in shallow …

Exploring the Overlap, Saliency, and Consistency of Environmental Predictors in Crime Hot Spots: A Remote Systematic Social Observation and Case-Control Examination
… units will be compared based on the presence of spatially joined crime generators and attractors and environmental disorder indicators recorded via remote systematic social observation using Google Street View. In addition to uncovering the strongest environmental predictors significantly more …

Development of a tool for automatic segmentation of the cerebellum in MR images of children
… used in the construction of the atlas, yielded spatial overlaps with manual segmentations greater than 70% in all lobules, except lobules VIIb and X. Average spatial overlap of the whole cerebellar cortex was 86%, compared to 78% using the alternative Spatially Unbiased Infra-tentorial Template …

Mapping inter-subject and inter-regional brain connectivity during free viewing of novel natural scenes
… between the percentage of region-specific overlap, which is the percent of the anatomical region of interest which contains spatial activation exhibited by all six subjects, and corresponding temporal correlation values between subjects from those regions. In this study, a controlled …

Evaluating Campylobacter spp at the human-wildlife interface
… In countries like Botswana, there is significant spatial overlap between humans and wildlife with a large proportion of the population vulnerable to Campylobacter infection, making Botswana an ideal location to study these interactions. This thesis reviews mammalian wildlife species that have been …

Drugs and Deportation on the Border: Post-Deportation Geographies of Enforcement and Conflict
… while crossing the border, showing how spatial overlap and other enforcement mechanisms have pushed these two activities into largely shared terrain. The third article addresses migrant kidnapping and the different purposes that it serves for transnational criminal organizations. Through …

Multiresonant Plasmonics with Spatial Mode Overlap
… called "multiresonant plasmonic systems with spatial mode overlap". We start by a literature review to elucidate the importance of this topic as well as its current and potential applications. Then, we briefly discuss the fundamentals of plasmonic resonances and mode hybridization to …

Ecological separation of the black and blue wildebeest on Ezemvelo Nature Reserve in the highveld grasslands of South Africa
… in the study area during the study period. Spatial overlap between the black and blue wildebeest was found to be low. Little evidence of interference interspecific competition between the black and blue wildebeest was found. It was, however, concluded that exploitative competition between …

Social organisation, ecology and conservation of loris tardigradus tardigradus (lorisformes; primates)
… significant inter- or intra-sexual differences. Overlap was significantly higher inter-sexually than intra-sexually. Lorises formed spatial pairs with coinciding home ranges and little overlap with neighbouring animals and had high indices of territoriality. Lorises were social 21.4% of the time, …

The influence of an ecosystem engineer on nutrient subsidies and fish invasions in southwestern Montana
… with higher brook charr densities, and increased spatial overlap between these species. In contrast, young-of-theyear cutthroat in invaded streams maintained high growth rates with beaver present, but showed growth reductions without beaver. Thus beaver conveyed both negative and positive impacts …

DISEASE IMPACTS ON MOOSE (ALCES ALCES) HEALTH AND ECOLOGY ALONG THEIR SOUTHERN RANGE LIMITS: PARASITES AS A LIMITING FACTOR IN NEW YORK
… infect and sometimes kill moose, resulting from spatial overlap with the parasites’ definitive host, white-tailed deer (Odocoileus virginianus). To determine whether parasites function as a limiting factor for the low-density moose population in New York, I first evaluated the status of and …

Gastrointestinal Parasite infections in Chacma Baboons (Papio ursinus) of the Cape Peninsula, South Africa: the influence of individual, group, and anthropogenic factors

Photonic crystal enhancement and tuning of quantum dot emission
… embedded within the dielectric changes its spatial overlap with the resonant mode. The first real-time tuning of PC-enhanced QD emission is successfully performed by fabricating QD embedded PCs on the surface of an acoustic MEMs resonator. As the RF modulation deforms the piezoelectric …

Ecological insight into three neotropical deer species: A study of spatial and diel distributions of white-tailed, Central American red brocket, and Yucatan brown brocket deer in northern Belize, Central America
… in the Greater Belize Maya Forest, we tested the spatial and temporal dimensions of niche partitioning among three sympatric deer species: white-tailed deer (Odocoileus virginianus nemoralis; WTD), Central American red brocket deer (Mazama temama; RBD), and Yucatan brown brocket deer (Odocoileus …

Seabird use of tidal stream environments and potential interactions with tidal energy devices
… Scotland, were trialled.<br/>Assessing the spatial overlap of seabird foraging distributions (areas of “high risk”) with tidal development and lease sites revealed the importance of species and scale. I found that the smaller the site, the less overlap there was. While this was the case for …
