This concept protects very rare species or habitats, exceptional concentrations of wildlife, or large landscape-level areas of forest.
Vulnerability has been used to define hotspots, which Myers (1988, 1990) and Myers et al. (2000) defined as localities with exceptional concentrations of species and levels of endemism, and exceptional degrees of threat.
The Eastern Arc and coastal forests of East Africa have been identified as a biodiversity hotspot: an area featuring exceptional concentrations of endemic species and experiencing severe habitat loss [ 1].
An exceptional high concentration of Chromium was found in some locations.
But "The Shadow of Night" is exceptional in its concentration.
Perhaps video bingers show exceptional long-term concentration that goes against the ADD-ing of America.
Nuclear imaging has the benefits of high intrinsic sensitivity, recognising targets present in a very low concentration, exceptional penetration of tissues, whole-body visualisation, and a large range of available, clinically tested tracers and consequently a high specificity [ 1, 2].
Bodipy 1 is an excellent fluorophore, with exceptional brightness at the concentration used (Fig. 8).
But this concentration is exceptional and even levels above 10 μg/L were observed rarely [ 30].
This was due to one exceptional high PCB-77 concentration (6.79 pg/g fat) in autumn milk samples.
