Prophylaxis

Pseudorandom Number Generators,1991) prevent qualitative estimates of what Ehrlich and Wilson (1991) describe as “the epidemic of extinctions now underway.” Such uncertainty complicates the formulation of effective public policy directed at preserving biological diversity.

Sagarika Panda,Haritha Indulekha interest groups. Unfortunately, in many salmon management decisions, the non-biological interests have taken precedence over the biological resource (Wright, 1981; Fraidenburg and Lincoln, 1985; Walters and Riddell, 1986). Each of these may have been a responsible decision, but in aggregate they cr
