Torpor is a highly effective response to counter various ecological and physiological
bottlenecks in endotherms. In this study, we examined interrelations between …

Deserts are physiologically challenging environments for birds, with scarce, unpredictable
water resources combined with air temperatures (T air) regularly exceeding avian body …

Endotherms dissipate heat to the environment to maintain a stable body temperature at high
ambient temperatures, which requires them to maintain a balance between heat dissipation …

Torpor is a controlled reduction of metabolism and body temperature, and its appropriate
use allows small birds to adapt to and survive challenging conditions. However, despite its …

Nocturnally active birds roosting in exposed microsites can experience operative
temperatures (T e) that markedly differ from air temperature (T a). Thus, quantifying T e …

Heat tolerance for many birds under climate and land use change scenarios could be
compromised in the future. Common Nighthawks (Chordeiles minor) belong to the …

The field metabolic rate (FMR) of an endothermic animal represents its energy expenditure
in a natural environment, or its energy budget, and its field water flux (FWF) reflects the …

Mechanical cutting and mastication of juniper trees aims to restore grassland habitat by
reducing the density of encroaching woody species. However, the associated soil …

Natural nesting habitat for Common Nighthawks (Chordeiles minor) in the Northern Prairie
region of North America is in decline due to row-crop conversion. Other nesting habitats …

Nocturnally active birds roosting in exposed diurnal microsites with intense solar radiation
can experience operative temperatures (Te) that markedly differ from air temperature (Ta) …
