Effect Of Sleep Loss On Executive Function And Baseline Corticosterone Levels In An Arctic-Breeding Songbird, The Lapland Longspur (Calcarius Lapponicus), Brett Hodinka

Masters Theses & Specialist Projects

Sleep is a fundamental and essential component of vertebrate life, although its exact function remains unknown. Animals that are deprived of sleep typically show reduced neurobiological performance, health, and in some cases, survival. However, a number of animals exhibit adaptations that permit them to carry out normal activities even when sleep is restricted or deprived. Lapland longspurs (Calcarius lapponicus), arctic-breeding passerine birds, exhibit around-the-clock activity during their short breeding season, with an inactive period of only 3–4 h/day (71°N). Whether these birds suffer behavioral and physiological costs associated with acute sleep loss (SL) is unknown. To assess ...
