Effects of Timber Harvesting on Terrestrial Salamander Abundance and Behavior
… in harvested and control habitats. Instantaneous rates of salamander activity ranged from 1.3 to 11.7% of the population for redback (Plethodon cinereus) and slimy salamanders (P. glutinosus). Timber harvest caused up to a 2-fold increase or decrease in activity rates. There was evidence for bias …

Processes and community structure in microbial biofilms of the River Elbe: relation to nutrient dynamics and particulate organic matter
… the upper sediment layers, as highest microbial activity could be expected due to increased import of nutrients. Dissolved oxygen is suggested to control the nitrogen dynamics in the hyporheic zone, as dissolved oxygen in the flowing water varied seasonally and diurnally due to the photosynthetic …

Assessing Thermal Comfort in Deep Underground Mines
… Optimal ambient air temperatures, humidities and activity rates of miners for comfort are also predicted. The analysis determined the optimal air velocity for thermal comfort to be 1.5 m/s. The results also detected humidity to contribute more to deviations from thermal comfort compared to other …

Mammalian habitat use along a residential development gradient in northern Colorado
… Multiple-season species occupancy and relative activity (frequency of detections) were measured in summer and winter seasons and these data were analyzed in conjunction with a novel, acoustic-based approach to assessing human activity. Impacts of exurban housing varied by mammal species, with …

Stress eating? Causes and consequences of variation in foraging behavior in a challenging world
… I explore whether glucocorticoids affect total activity and offspring feeding rate. Birds with experimentally elevated corticosterone (the primary glucocorticoid hormone in birds) were initially less active and fed their nestlings at lower rates than control birds. However, as the provisioning …
