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 …

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 …

IMPACTS OF DIURNALLY EXPOSED SLIME LAYER HYDROGEN SULFIDE CONCENTRATIONS IN SEWER ATMOSPHERE
… recent development and introduction of H2S data loggers has shown that H2S concentrations in the sewer headspace demonstrate a diurnal pattern that is not explained by current models. Odor complaints and toxicity are primarily a result of the peak concentration levels and may be more …

A Comparison of the Singing Activity of Carolina Wrens <i>(Thryothorus Ludovicianus)</i>) in Urban and Rural Settings
… activity in urban and rural settings. I analyzed data from 4 SongMeter© SM2 data loggers (2 located at an urban park in Bowling Green, KY and 2 located at a rural preserve in Hart County, KY). The data loggers were programmed to record ambient sound for 3 minutes at the beginning of every hour. A …

Estudio comparativo de iluminancias globales en superficies horizontales mediante distintas orientaciones de la fachada de un modelo a escala para optimizar la iluminación natural en el interior.
… de datos recibidos por los sensores, llamados Data Loggers. Los Data Loggers son la instrumentación utilizada para la recogida de datos y posterior almacenamiento en formato digital en ordenador para que estos datos puedan ser tratados mediante hojas de cálculo, tablas y gráficas de datos para …

A Method for Detecting Nesting Activity, Thermal Implications of Different Nesting Strategies, and Activity Patterns of Ornate Box Turtles (Terrapene Ornata)
… ratios of this temperature-dependent species. Data loggers placed into nest cavities revealed that underground nesting did not affect mean incubation temperatures, but the behavior reduced thermal variation of incubation temperatures. Automated telemetry was also used to quantify activity …

Physiological Plasticity and Ecology of the Yellow Mud Turtle (Kinosternon Flavescens) During Hibernation
… by warming winter temperatures. Temperature data collected by data loggers attached to turtles hibernating in the field were compared with soil temperature data. Turtles hibernated at a mean temperature of 9.0°;C and depth of 54 cm. To assess physiological capacity to tolerate variable winter …

Heterogeneidade espacial e variação temporal do microclima e seus efeitos sobre a ocorrência de três espécies de marsupiais na Mata Atlântica
… and luminosity) was developed, where were used data loggers, a programmed reading equipment of climatic parameters. To characterize the microhabitat were measured eight variables proposed in Freitas et al. (2002). The developed and tested method is efficcient in the study of environment of small …

The use of activity measures in combination with physiological factors as indicators of disease in dairy cattle
… the use of the Afi PedometerPlus© and HOBO® data loggers. E.coli mastitis altered animal activity and improvement in DMI and milk production of animals given FM was observed, thus providing evidence for the use of an NSAID as supportive therapy for mastitis. Additionally, activity and blood …

Seasonal Variation in Whole Stream Metabolism across Varying Land Use Types
… and developed land use / land cover types. Data loggers were deployed to collect continuous oxygen, temperature, conductivity, and stage height data from 2010-2011. I used these data to estimate gross primary production (GPP) and ecosystem respiration (ER). GPP and ER were compared to stream …

ECOLOGICAL AND PHYSIOLOGICAL MECHANISMS OF BIOLOGICAL RHYTHMS IN A POLAR-BREEDING SEABIRD
… indirect measurements obtained from bird-borne data-loggers indicated the possible presence of diel vertical migration of their prey during polar day. Together this body of work adds to our understanding of biological rhythms in the polar environment.

Changes in the seasonal activity of bats occuring in the Kunene region, Namibia: Influence of environmental factors
… Hoanib (271 m). Temperatures were measured with data loggers at sampling sites and moonlight was compared using lunar phases. Activity was positively correlated with temperature at all sites and rarely occurred when temperatures were ≤ 11°C. Moon lunar phase did not affect activity as there was …

Evaluation of Mob Grazing and its Impacts on Soil Moisture and Temperature and Litter Decomposition in South Dakota
… temperature, soil sensors connected to automated data loggers were installed below each treatment. Litter bags were installed on the treatments post grazing. Two types of litter with two replicates were installed on every treatment. Types of litter were classified as: old and new. Litter bags were …

Ecophysiology of Hibernating Eastern Red Bats (Lasiurus Borealis)
… and arousals at various Ta. Based on these data, I was able to estimate a winter energy budget for this species within a selected temperature profile. Bats were captures during fall of 2003 and 2004 in southwestern Missouri and kept in captivity during the winter seasons in environmental …

Thermoenergetics of Indiana Bats
… determined at 3,5,7, and 9°C by the use of iBBat data loggers affixed to the bat's back. Oxygen consumption rates at 1,3,5,7, and 9°C were measured in metabolic chambers. Metabolic rates declined with decreasing temperature to 5°C, then increased to 1°C. Arousals accurred more frequently at higher …

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, …

A Vascular Flora of the Sacatar Trail Wilderness, Sierra Nevada, California
… as 32 non-native taxa. Additionally, temperature data loggers were installed, and vegetation surveys were conducted along two transects spanning the study area’s elevational gradient at 305 m (1000 ft) intervals. This was done to associate localized temperature ranges with plant distribution and …

Comparison of the Different Hazards Experienced by Pallets During Material Handling
… instrumented with Lansmont SAVER 3X90 and 3D15 data loggers to measure the acceleration peak, g of shock impacts, duration of impacts, random vibration intensity and RMS (g) values during forklift handling in the field. The highest vibration levels were observed for distribution facilities with …

Nest emergence phenology of the Northern Map turtle (Graptemys geographica) near its northern range limit
… geographica), for which we have limited data on nest phenology from only two locales in the USA. Hatchling emergence from the nest is not a straightforward product of time since oviposition, varies among species, and is not well understood. Map turtle hatchlings have been shown to be …
