To ascertain the inheritance of responses to changing atmospheric CO(2) content, we partitioned response to elevated CO(2) in Plantago lanceolata between families and populations in 18 families in two populations. Plants were grown in 35 Pa and 71 Pa

A population of the grass Danthonia spicata growing in a pine–hardwood forest in northern lower Michigan was studied before, during, and after a period of major disturbance. Samples of the aboveground population were collected after clear-cutting b

The relative abundance of native species in both the Cactaceae and Crassulaceae in different regions of North America is highly negatively correlated with the coefficient of humidity, an estimate of soil moisture content. The species of both families

High arctic plants of Saxifraga rivularis require nearly continuous (23 or more h/day) irradiance of 0.3 ly/min for induction of floral development in growth chambers. A daily dark period of several hours' duration, or a daily low intensity irradianc

A stepwise multiple regression analysis was used in an attempt to correlate statistically the geographic patterns in the abundance of C4 grasses with patterns in climatic variables. The percent of grasses having the C4 pathway was computed for the to

The growth, biomass δ13C values, and ability to accumulate titratable acidity at night were compared in eight environmental treatments for Cremnophila linguifolia, Sedum greggii, and their F1 hybrid. In the phytotron, differences in treatment daylen

The chloroplasts of two species of the Crassulaceae and their F1 hybrid were compared by electron microscopy. The two species had contrasting leaf tissue δ13C values of −25°/∞ (Sedum greggii) and −13°/∞ (Cremnophila linguifolia), and the F

Populations of Danthonia spicata were studied from sites of ages 0, 26, 32, 44, and 69 years after fire in the aspen–pine forests of northern lower Michigan. Along this gradient the environment changes from unshaded and dry to a shaded, moist pine

The δ13C values of whole body samples of the beetle Tribolium castaneum are closely correlated with the δ13C values of the plant carbon in its diet. The correlation is always high for diets ranging from 100% C4 to 100% C3 plant material. The degree
