A number of hemodynamic, pharmacologic and metabolic interventions were found to change the extent of acute ischemic injury of the myocardium and subsequent necrosis following experimental coronary artery occlusion. Reduction in myocardial damage occurred by decreasing myocardial oxygen demands (beta-adrenergic blocking agents, intra-aortic balloon counterpulsation, external counterpulsation, nitroglycerin, decreasing afterload in hypertensive patients, inhibition of lipolysis, and digitalis in the failing heart); by increasing myocardial oxygen supply either directly (coronary artery reperfusion or elevating arterial pO2), or through collateral vessels (elevation of coronary perfusion pressure by alpha-adrenergic...
Increasingly, environmental quality is becoming recognized as a critical factor that should constrain land use planning. One important measure of a landscape's quality is its capacity to support viable populations of wildlife species. But the ability of land managers to balance conservation with other competing objectives is limited by a shortage of methodologies for assessing landscape quality. In response to this shortage, the research community has begun developing a variety of multispecies, landscape-level, assessment models. Useful models must strike a balance between parsimony and biological realism and must be designed to make the most of limited life history data. This paper applies two such assessments...
Species conservation via the Endangered Species Act is highly politicized, yet few data have been gathered to illustrate the relationship of political party affiliation to species conservation perspectives. We conducted a nationwide public opinion survey and found that Democrats value species conservation more highly than do Republicans, and that Democrats are also more strongly supportive of the Endangered Species Act. Republicans place higher value on property rights than do Democrats, but members of both parties value economic growth as highly as wildlife conservation. The results imply that the Democratic propensity to value species conservation reflects a biocentric perspective that does not bode well for practical...
