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 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

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,

In the USA and Canada, methylcyclopentadienyl manganese (MMT) is currently added to gasoline to replace tetraethyl lead as an antiknock fuel additive. Manganese concentrations in roadside soil and plants are increasing and correlated with distance fr
