Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms. Since quality is likely to vary among patches of habitat, it is important to consider how a low quality patch might affect a population. In this model, organisms occupy two patches of habitat. One patch, the source, is a high quality habitat that on average allows the population to increase. The second patch, the sink, is very low quality habitat that, on its own, would not be able to support a population. However, if the excess of individuals produced in the source frequently moves to the sink, the sink population can persist indefinitely. Organisms are generally assumed to be able to distinguish between high and low quality

El segundo subtipo, el sumidero, es un hábitat de muy baja calidad que, por sí solo no podría mantener a una población. Sin embargo, un exceso de individuos en la fuente puede trasladarse con frecuencia al sumidero, lo cual puede hacer que la población del sumidero persista indefinidamente, pese a sus restricciones. En general, se supone que los organismos pueden distinguir entre hábitats de alta y baja calidad, y prefieren hábitats de alta calidad. Sin embargo, los postulados sobre trampas ecológicas describen las razones por las que los organismos podrían preferir, en determinados casos, áreas de sumidero en lugar de áreas fuente. Finalmente, el modelo de fuente-sumidero implica que algunas porciones de hábitat por sobre otras pueden ser más importantes para la supervivencia a largo plazo de una población, y que su estudio puede mejorar la toma de decisiones de administradores de sitios de interés ecológico en pos de una correcta conservación.

However, if the excess of individuals produced in the source frequently moves to the sink, the sink population can persist indefinitely. Organisms are generally assumed to be able to distinguish between high and low quality habitat, and to prefer high quality habitat. However, ecological trap theory describes the reasons why organisms may actually prefer sink patches over source patches. Finally, the source-sink model implies that some habitat patches may be more important to the long-term survival of the population, and considering the presence of source-sink dynamics will help inform conservation decisions.
