Therefore, caution is advisable when designing conservation strategies based on molecular marker studies or a limited number of populations.
Characterizing the timing, severity, and agents of historic forest disturbances is critical to developing management and conservation strategies based on natural processes.
These landscapes confound and challenge conservation strategies based on modern ecological theory with the sociological realities of relatively higher human densities, less land available for conservation, higher poaching pressure, and less political and financial support for conservation.
The study shows that the richness and composition of bryophytes and lichens differ between the three set-aside types and consequently, the outcome of large-scale conservation strategies based on anyone type would be different.
Therefore, conservation strategies based heavily on neutral genetic variation, with an under-emphasis on the distribution of non-neutral variation, risk detrimental impacts to locally adapted population segments and should be scrutinized (Pearman 2001; Schwartz et al. 2009).
In both species, the neutral and adaptive diversities within and among populations were not correlated, so conservation strategies based on one type of index would not select the same populations for protection.
The environmental groups will coordinate an assault on the plan next week when it is released, with local demonstrations and lobbying efforts to steer Congress toward a strategy based on efficiency, conservation and renewable resources, leaders of several organizations said today.
