Monitoring forest carbon sequestration with remote sensing and carbon cycle modeling.

Sources and sinks of carbon associated with forests depend strongly on the management regime and spatial patterns in potential productivity. Satellite remote sensing can provide spatially explicit information on land cover, standage class, and harvesting. Carbon-cycle process models coupled to regional climate databases can provide information on potential rates of production and related rates of decomposition.

Health survey of house finches (Carpodacus mexicanus) from Wisconsin.

We conducted a health survey of house finches (Carpodacus mexicanus) without evidence of Mycoplasma gallisepticum infection in order to establish baseline population health measures and estimate prevalence of potential pathogens likely to influence host susceptibility to mycoplasmosis. Seasonal changes in several physiologic parameters were observed. Weights were greater in winter compared with the breeding season (P < 0.

Responses to ozone of varieties of common bean (Phaseolus vulgar is L.).

Varying modes of ozone sensitivity were detected in 12 varieties of Phaseolus vulgaris. Seedlings were exposed to 0.4-0.
