Survey Techniques to Examine Morphological Evolution of Coastal Regions
… in Duck. The 22,500 m2 area of interest was surveyed daily by a walker carrying a GPS-equipped backpack and occasionally with a lidar equipped drone. Surveys of the northern region of interest also were collected with a stationary terrestrial lidar mounted on the dune. The observed …

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 …

An investigation as to the suitability and effectiveness of geophysical survey techniques as a tool to aid archaeological interpretation of upland sites within the area of south east Wales
Geophysical survey as a tool to aid archaeological interpretation has been shown to be of varied usefulness across the differing site morphology and underlying geology of Wales. Its uptake has also varied greatly between regions with bias often existing towards certain types of site or particular …

Environmental Factors Influencing Spring Migration Chronology of Lesser Scaup (Aythya affinis)
… I used satellite telemetry data, waterfowl survey data and corresponding weather data to evaluate competing models that explained variation in timing and rate of migration by lesser scaup. Timing of spring migration occurred earlier and faster when lesser scaup encountered warmer …

Phylogeographic and environmental DNA analysis of the mudpuppy (necturus maculosus maculosus)
… DNA analysis complements traditional survey techniques and increases confidence when determining species’ range. Here, we explore the phylogeography of the mudpuppy’s western range and examine the feasibility of using eDNA to complement traditional surveys. Results show a deep …

Comparison of Invasive and Non-Invasive Techniques for Measuring Fiddler Crab Density in a Salt Marsh
… of burrowing crabs is challenging, and several techniques have been developed to accomplish it, including burrow counting, visual surveys of surface-active crabs, and substrate excavation. These techniques have been compared in mangrove forests but not in a salt marsh, nor has anyone attempted …

Land Cover Land Use Change and Soil Organic Carbon Under Climate Variability in the Semi-Arid West African Sahel (1960-2050)
… of remote sensing analyses, qualitative social survey techniques, and biogeochemical modeling was used to study the relationships between climate change, LCLU change and soil organic carbon in the semiarid rural zone of Senegal between 1960 and 2050. For this purpose, four research hypotheses …

The relationship between selected characteristics of health education programs and the acquisition of student health knowledge in secondary schools of the state of Virginia
… the state of Virginia were obtained by standard survey techniques in order to investigate the relationship of selected variables to the acquisition of health-related topics. A health education research questionnaire filled out by respective teachers (N = 50) was used to determine teacher …

Seismic Tomography for the Integrity Assessment of Earthen Dams and Levees.
… is not an option. Even though seismic techniques provide valuable information of the subsurface strata, the interpretation is not always uniform and consistent. In this research, three seismic survey techniques, known as seismic refraction, Multichannel Analysis of Surface Waves (MASW) …

VERTEBRATE COMMUNITY CHANGES ACROSS A 3200M AMAZON-TO-ANDES GRADIENT: COMPOSITION, STRUCTURE, AND OCCUPANCY
… are poorly known and depend on field survey techniques which may not capture the full extent of an animals’ range. Here we present findings from two camera surveys in 2013 and 2016 conducted in and near Manu National Park, Peru. In 2013, 53 camera traps were installed between 3693 …
