Loggers' perceptions of the costs of best management practices on timber harvesting operations in Virginia
… zones, stream crossings, and site stabilization. Loggers provided an estimate of the cost or expense for constructing each BMP. They gave an indication of how costly these practices were to implement. The responses for each BMP were then stratified by region to determine if there were regional …

EVALUATION OF BEDROCK DEPTH AND SOIL INFILTRATION ALONG PENNYPACK CREEK USING ELECTRICAL RESISTIVITY TOMOGRAPHY AND MOISTURE LOGGERS
… The goal of this study was to use soil moisture loggers and electrical resistivity tomography (ERT) along the Pennypack Creek (Philadelphia, PA) to evaluate soil infiltration and bedrock depth in urban areas to ultimately access their impact on critical zone modeling. ERT was also used to …

An evaluation of timber harvest planning training on logging quality in the Virginia Piedmont
… in the Virginia Piedmont. Nine randomly chosen loggers (study group) from the Virginia Piedmont participated in two days of intensive harvest planning field training. Nine additional loggers were randomly chosen as a control group. Study loggers prepared and followed written timber harvest plans …

Performance and efficiency evaluation of logging contractors using data envelopment analysis
… considerably less efficient than their peers. Loggers tended to move from period of high efficiency to period of lesser efficiency, although some were considerably more stable than others. Of those contractors who displayed the most stability in regard to technical efficiency, a majority could …

Lumberjacks, Muscular Christianity, and Nation Building: Creating an Aspirational Canadian Masculinity, 1820 – 1912
… of the nineteenth century, public perception of loggers slowly began to change, and the public started to view lumberjacks as a new masculine ideal and symbol of a Canadian national identity. Examining Canadian literature, both fiction and non-fiction, through gender and cultural history …

Seasonal patterns in body temperature and behaviour in Cape ground squirrels, Xerus inauris, living in a semi-arid environment
Miniature temperature-sensitive data loggers were implanted into the abdominal cavities of 16 free-ranging Cape ground squirrels, Xerus inauris, to investigate seasonal body temperature patterns. Data loggers recorded body temperature at 5-min intervals while microclimate variables were recorded in …

Remotely sensing motion: the use of multiple biologging technologies to detect fine-scale, at-sea behaviour of breeding seabirds in a variable Southern Ocean environment
… from finescale data. After describing the loggers used and the methods of deployment in Chapter 2, I assess the effect that sampling rates have on metrics derived from GPS loggers in Chapter 3. This was done by sub-sampling GPS tracks recorded at 1-s sampling intervals, showing the effect …

Acoustic travel time perturbations due to an internal tide and internal wave field in the Barents Sea
… spectra are calculated from Brancker temperature loggers which were deployed on moorings in the Barents Sea during the August 1992 Barents Sea Polar Front Experiment. In particular, the first three internal wave mode amplitudes are estimated from the four Brancker temperature loggers on the …

MONITORING STORMWATER INFILTRATION IN A VACANT LOT COMPARING TIME-LAPSE ELECTROMAGNETIC INDUCTION AND ELECTRICAL RESISTIVITY TOMOGRAPHY
… most useful point measurement was soil moisture loggers. Data from soil moisture loggers was used to parameterize the model; in addition, the soil moisture loggers showed a slow drying period. By combining the EM Profiler method with soil moisture data and applying corrections for drift, some …

Anticipated Impact of a Vibrant Wood-to-Energy Market on the U.S. South's Wood Supply Chain
… study than in previous research that employed loggers with less expensive, more fuel efficient equipment. This suggests that high capacity, wet-site capable loggers may not be able to economically harvest and transport energywood without a substantial increase in energywood prices. This study …

The distribution and objectives of local forestry-related ordinances in the United States
… are not viewed as being overly burdensome by loggers and pulpwood operators. For these reasons, local forest laws may impose less of a burden than their sheer numbers would suggest. Although forest ordinances have been extremely burdensome to loggers and forest landowners in certain areas, …

Foraging ecology of the African Penguin Spheniscus demersus in relation to ocean physical processes.
… research demonstrated the dual utility of bio-loggers as a method for generating accurate, high-resolution oceanographic data. These data can be used in future studies, generating a cross disciplinary platform for research. The thesis augments our knowledge base of the African Penguins foraging …

Investigating Subsurface Flow Delivery to a Small High Arctic River
… µS/cm). This work demonstrates these economical loggers can be calibrated and applied to quantify EC in the field with accuracies comparable to commercial loggers.

Environmental governance and implications of small-scale logging: the case of the indigenous groups in the Ampiyacu Basin in the northeastern Peruvian Amazon
… to an urban market, and access to funding. Most loggers are poor, earning less than $ 496/year in cash, although income levels varied widely within type of funding. The higher income loggers are specialists who log more than the permissible quota and have greater access to funding. Timber was the …

The impact of group selection silviculture on timber harvesting cost in the southern Appalachians
… and cost data from typical Appalachian loggers operating on group-selection timber sales. Three logging systems were chosen for the study: (1) cable yarder ,(skyline) system; (2) feller-buncher/cable skidder system; and (3) motor-manual chainsaw felling/cable skidding system. At least …

Safety Training for Spanish-Speaking Workers in the Logging Industry in the Southeastern United States
… during the summer of 2005 by 41 selected sample loggers who employ Spanish-speaking workers, in which they addressed the previous and present safety training received by Spanish-speaking workers, in addition to other information pertaining to safety. The percentage of Spanish-speaking workers in …

Technology in ecology: determining the location, behaviour, and energy expenditure of free-ranging carnivores
Animal-attached data loggers are used increasingly to collect movement and behaviour information to advise species management and answer key ecological questions about their habitat use, activity, and energetics. Biologgers are especially important for monitoring cryptic animals such as carnivores, …

Influences of varying stand harvest methods on timber harvesting costs in southwestern Virginia hardwoods
… selection tract as compared to a clearcut. Eight loggers were contacted and interviewed to obtain data on their costs of logging. The mean, median, and standard deviation of the responses were calculated to develop a profile. Mean crew size was three men, including the owner operator. Mechanized …

Linking foraging behaviour of post-breeding adult female elephant seals from Marion Island to physical dynamics and productivity at the South-West Indian Ridge
… temperature and depth satellite-relayed data loggers (CTD-SRDL's) and their foraging behaviour was examined in relation to different chlorophyII-a concentrations. Optimal foraging and area restricted search theories predict that travelling speed and turning frequency would be quantifiably …

Analysing stormwater temperature at site-specific discharge points along the Liesbeek River, South Africa
… makes use of Thermocron iButton Temperature Loggers. These were placed in four stormwater outlet pipes, which frequently discharge event-based stormwater runoff into the Liesbeek River. Additionally, iButton loggers were placed in the river channel, to provide a reference temperature to …
