Many countries, including Australia, the Netherlands, Rwanda, Thailand and Russia (Smith, 1992; Marufu et al., 1995) have legislated requirements for minimum populations of target organisms and contaminants per weight unit of inoculants.
In contrast, using information on migratory connectivity allowed us to set targets for maintaining minimum population sizes within each breeding region, thereby dramatically changing the decision pathways and improving the regional stability thousands of kilometers away on breeding areas.
Thereby we obtained the lower boundary for the minimum population size necessary to avoid extinction through inequality (4).
Estimates for a necessary minimum population to maintain genetic effectiveness range between 100 and 150 animals.
The following year, voters approved the commission's proposals to eliminate at-large seats, end the minimum population requirement for community districts and overhaul the procedure for redrawing City Council districts.
A successful conservation strategy should take the ecology of the species into account and evaluate the minimum population size required for persistence for a specific amount of time with high probability [12].
Although an ideal minimum population size for genetic variability would be around 200 horses, the current range cannot support this population given the average rainfall.
The estimate derived from extreme decay rate values provides what we believe to be an absolute minimum population size for the entire plantation area.
The 1,000-km2 area of the NR within YNP is characterized by lower elevations (1,500 2,200 m), serves as prime wintering habitat for the park's ungulates [25], and supports a higher density of wolves than the Interior (20 99 wolves/1000 km2 versus 2 11 wolves/1000 kminimum; minimum population count for entire YNP ranged between 118 and 172 wolves between 2000 and 2007 [27]).
It is desirable that every spatial unit has a minimum population scale for maintaining medical resources.
