It is a reproduction strategy identified in some natural environments valid for stable environments with a low rate of natural ecosystems disorder. Typical large bodies, long half-life and late reproductive age. Species are based balance and adjust their population dynamics in populations around the K value or capacity (the maximum number of individuals that the ecosystem can support without being damaged species).
Stable systems generate highly developed species, which in turn generate this strategy with great success. Large mammals use this strategy: they have few offspring, allowing them to invest heavily in their care and development. This maximizes the chances of success of the next generation. We as a species, are the culmination of the development of this strategy.
The problem with this strategy is that survival depends very stable environments, which makes the species that inhabit them are very sensitive (fragile) to unexpected changes in the environment. A change in market trend, new technology, fashion, or a legislative change, can end up with a whole market, and the companies operating in it. A specialized liked the stability, and therefore does not like changes.
A further specialization increased fragility. Specialization is an advantage only to defend niches (or survive in natural areas) very small. The turntable needle manufacturers and bearded know well what I mean.
To summarize: The population of R-dependent species that reproduce quickly, as quickly as added chance of survival by creating or identifying opportunities. The type K depend on the carrying capacity of the habitat, i.e. is the maximum population size that the ecosystem can support without the species that inhabit it from damage, depend on the ability of the market to absorb the supply and of its competitors.0
