Poa secunda Presl. is one of the few native perennial bunchgrasses in the Intermountain West to persist and co-occur with the invasive annual Bromus tectorum L. following widespread overgrazing and frequent wildfires. To identify potential mechanisms

Specific metabolic heat rates (Rq) and respiration rates (RCO2) of adult Harmonia axyridis Pallas, the multicolored Asian lady beetle, and Hippodamia convergens Guerrin-Manaville, the convergent lady beetle, were measured in isothermal calorimeters a

A thermodynamic law of adaptation of plants to temperature is developed. Plant growth rate is proportional to the product of the metabolic rate and the metabolic efficiency for production of anabolic products. Over much of the growth temperature rang

This study tested the hypotheses that plant respiration and photosynthesis are genetically adapted to the native climate and that plant metabolism has little ability to acclimate to a non-native climate. Seeds from four geographically distinct seed s

The two calorespirometric ratios, the ratio of metabolic heat rate to the rate of CO2 production and the ratio of metabolic heat rate to the rate of O2 uptake (Rq/ R C O 2 and Rq/ R O 2 , respectively), provide different information about the activit

In a common garden study, seedlings of Pseudotsuga menziesii (Douglas-fir) var. menziesii (coastal) from Lacomb, Oregon and P. menzeisii var. glauca (interior) from Clearwater National Forest, Idaho, and their F 2 hybrids were grown in nursery beds i

The multicolored Asian lady beetle, Harmonia axyridis (Pallas), is displacing native coccinellid species in North America. To elucidate the mechanisms underlying this phenomenon, it is important to understand its physiological ecology. Hence, this st

The enthalpy change for anabolism is needed to model the growth/respiration relation in plants. If all CO 2 production is assigned to catabolism, the anabolic reaction becomes C substrate →C products + x O 2 with an enthalpy change, Δ H b . Four m

Big sagebrush or Artemisia tridentata Nutt. ssp. vaseyana grows at slightly higher, cooler, and drier sites than does A. tridentata ssp. tridentata . The two sagebrush subspecies and natural hybrids between them are found along an elevational gradien

Cryptogamic crusts are communities composed of lichens, cyanobacteria, algae, mosses, and fungi. These integrated biological soil crusts are susceptible to disturbance, but if intact, appear to play a role in providing nutrients, especially nitrogen,
