Acclimation of activated sludge to pentachlorophenol
… dosage. This study intended to determine if: (1) acclimation to low levels of PCP would provide any protection to the biomass against detrimental effects of higher shock loads of pentachlorophenol; (2) PCP-acclimation would decrease the inhibitory effect of related priority pollutants; (3) PCP …

Barriers to Civilian and Familial Acclimation for Returning Veterans
Reintegration is a hard process for any returning service member to go through. For a number of veterans reintegration into communities and families is a tumultuous time of adjustment where many barriers must be faced. Some of these barriers include relationship stability, employment barriers, and …

PHYSIOLOGICAL ADAPTATIONS TO HEAT ACCLIMATION; REPERCUSSIONS ON CYCLING PERFORMANCE
… to intermittent sprint training during heat acclimation and the effect on intermittent sprint performance and 3) to examine the phenomena of cross- acclimation where the stressors of one environment (heat), might convey a performance benefit in alternative environments (cool and hypoxia). …

Physiological and genetic mechanism(s) of cold acclimation in Rhododendron
An in vitro laboratory protocol for assessing cold hardiness (CH) in rhododendrons based on electrolyte-leakage was developed. The raw leakage data were transformed into percent-adjusted injury, which showed high correlation with injury data based on visual observations. The percent-adjusted injury …

Describing the Ionoregulatory Changes that Underlie Cold Acclimation in Drosophila Melanogaster
… of K+ in the haemolymph (hyperkalemia). Cold-acclimation can mitigate these ion imbalances, but the physiological mechanisms that facilitate this process are still not understood. Upon adult emergence, D. melanogaster females were subjected to seven days at 25C (warm-acclimation) or 10C …

Are thermotolerance and heat acclimation related through the heat shock response?
… after an acute, severe heat exposure) and heat acclimation (systemic adaptations that improve heat dissipation following chronic heat exposure) have traditionally been considered separate phenomena. However, recent studies in animals suggest these adaptations may be related through the heat …

Ecology and ecophysiology of Zostera capensis: responses and acclimation to temperature
… significance of identifying characteristics and acclimation strategies that allow habitats to persist under climate change, and thus sustain biodiversity and productivity, as well as continue to provide important ecosystem services.

Acclimation of marine macrophytes (Saccharina latissima and Zostera marina) to water flow
… under low current velocities. Physiological acclimation to low water flow occurred via upregulation of DIC uptake mechanisms in both S. latissima and Z. marina. Both species increased their ability to generate CO2 in the boundary layer by increasing external carbonic anhydrase and in Z. …

Stomatal acclimation to dynamic light: implications for photosynthesis and water use efficiency
… and hydrological cycles at global scales. Plant acclimation to growth light environment has been studied extensively; however, the majority of these studies have focused on constant light intensity and photo-acclimation, with few studies exploring the impact of dynamic growth light on stomatal …

Impact of hypercarbia on juvenile fish physiology, behavior, performance, and acclimation potential
… and performance experiments to determine the acclimation capacity of fishes to chronic hypercarbia. Results from this study clearly indicated 1) acclimation to chronic hypercarbia causes plastic alterations in molecular and physiological parameters, 2) CO2-acclimated fish displayed a reduced …

In Hot Water: Thermal Acclimation is Insufficient to Save Corals in the Anthropocene
… and often leads to mortality. Current thermal acclimation theory states variation and gradual increases in temperature can ameliorate thermal stress. Indeed, there is evidence some coral species have some capacity to acclimatize to thermally variable environments, increased temperature, or …

Mechanisms of Acclimation of Photosynthesis and Leaf Growth to Water Deficits in Sunflower
… Both stomata and chloroplasts contributed to the acclimation. Leaf diffusive resistance at low (psi)(,l) was less in acclimated plants than control plants. Chloroplast activity, demonstrated in situ with measurements of quantum yield, capacity to fix CO(,2) at all partial pressures of CO(,2) …
