Even William K. Reilly, a former administrator of the agency, has admitted that Superfund's faulty assumptions "have driven clean-up costs to stratospheric levels and, together with liabilities associated with Superfund sites, have resulted in inner-city sites suitable for redevelopment remaining derelict and unproductive".
But in many cases, these areas provide only suboptimal habitat or the only suitable habitat remaining for species [50], and suffer from isolation, inadequate planning and management, stochastic events, and cover insufficient areas to maintain viable populations.
Kennedy et al. (2003) found threshold values for proportion of suitable habitat remaining in the landscape ranging from 5 to 80 % for birds, 6 15 % for mammals, and 20 60 % for invertebrates.
Of 95232 clones fingerprinted, 80553 were suitable for assembly; the remaining clones were eliminated due to unsuitable length, contamination, and other reasons.
In the high-emissions scenario, almost no suitable habitat remained for Blanding's turtle in Wisconsin by the 2050s and there was up to a 100,000-fold increase in landscape resistance to turtle movement, suggesting the landscape essentially becomes impassable.
In addition, the design methodologies of implantable flexible antennas suitable for biomedical research remain vigorously pursued topic [56].
Besides nursing their portfolio of ailing companies, venture capitalists also face the challenge of finding suitable investments for the remaining $40 billion they raised from pension funds and colleges in the last year.
The Victorian government has come under pressure to ban the clear felling of the central highlands, with just a fraction of older trees, which have hollows suitable for possum homes, still remaining.
None of the sample falls under "desirable for drinking" category, while 75% in both the seasons are suitable for irrigation and the remaining is out of condition for drinking and irrigational uses.
For cultivars requiring more than 700 hours of chilling, conditions deteriorated earlier, with only between 23 and 46% of the area remaining suitable for production by 2041 2060, and between 2 and 10% by 2080 2099, depending on the emissions scenario.
