Source-Sink Dynamics
Organizations have source and sink units.
In metapopulations, not all patches contribute equally to gene flow. Source populations in high-quality habitat have positive growth and export migrants. Sink populations in marginal habitat have negative growth and persist only through immigration from sources. Protecting sources is critical for metapopulation persistence; protecting sinks alone doesn't ensure survival.
Business Application of Source-Sink Dynamics
Organizations have source and sink units. Core profitable divisions (sources) fund exploratory units and struggling subsidiaries (sinks). Understanding which units are sources vs. sinks helps allocate resources and manage talent flow strategically.

Source populations in high-quality habitat export migrants; sink populations in marginal habitat persist only through immigration - protecting sources is critical.
