They believe Africa's wars, corruption and tribalism are "just the way Africa is", and that African societies are unable to sustain viable states.
Bioreactors have aided in hepatocyte survival and have proven to sustain viable cells for several weeks.
We applied these data to a female-based, stochastic, pre-breeding population model to examine whether current grassland management practices can sustain viable populations of breeding songbirds.
As the urbanisation is usually irreversible, the urban context has to be taken into account when defining appropriate management measures to sustain viable populations.
Due to their static nature, protected areas (PAs) are vulnerable to global change, and resident species will likely need to colonize new sites and exchange migrants to sustain viable local populations.
Across three Scottish regions (Argyll, Inverness and Galloway) habitat composition within 1 km of leks was similar at 45 60% moorland and 10 15% young forest suggesting this habitat composition may provide a template for designing mosaics that can sustain viable populations in the face of forest expansion.
In therapy, we find that even those who don't want to be controlled do want and need company to sustain viable alternatives.
For example, some of the individuals recorded in biodiversity samples could represent transient or sink populations and spill-over effects could mean that occasional species are recorded in modified land-uses even though they are unable to sustain viable populations in the long-term when isolated from source populations in primary habitat.
To sustain viable populations, it is essential that during the favourable phase of the hydrological cycle they recover from the population losses suffered during the unfavourable period (Junk and Piedade, 1997).
Until last week, I would have said that your best hope for being more than a bodiless brain in a chemical stew was the fact that no scientist was yet capable of sustaining a viable brain in a jar.
