Cell size and basal metabolic rate in hummingbirds Tamaño celular y tasa metabólica basal en picaflores

Revista Chilena de Historia Natural, 2005
Nucleotypic theory suggests that genome size play indirect roles in determining organismal fitness. Among endotherms this theory has been demonstrated by an inverse correlation between basal metabolic rate (BMR) and genome size. Nonetheless, accumulation

Effect of Temperature and Humidity on Evaporative Water Loss in Anna\u27s Hummingbird (Calypte anna)

, 1992
Evaporative water loss (EWL), oxygen concumption (V0 ), and body temperature (Tb) of Anna\u27s 2 Hummingbirds (Calypte anna; ca. 4.5 g) were measured at combinations of ambient temperature (T J and water vapor density (Qva) ranging from 20 to 37 °C and 2
