Marcadores moleculares y ecología del movimiento

Abstract

El estudio del movimiento es parte esencial del análisis ecológico a nivel de gen, individuo, población, comunidad y ecosistema. Los marcadores de ADN son herramientas muy útiles para el estudio del movimiento a todos estos niveles, permitiendo, por ejemplo, establecer relaciones de parentesco entre individuos, determinar el origen poblacional de individuos migrantes, estudiar sistemas de apareamiento, cuantificar la escala de interacciones interespecíficas, o caracterizar el patrón espacial de la dispersión y la competencia. A nivel de gen, los marcadores de ADN son imprescindibles para estudiar la estructura y el flujo genético dentro y entre poblaciones, así como su efecto combinado con otras fuerzas evolutivas y los factores bióticos y abióticos del medio sobre la adaptación local. En este artículo se revisan algunos métodos basados en marcadores de ADN que pueden resultar de utilidad en ecología del movimiento, identificándose áreas de estudio en las que se espera estos marcadores sean de especial utilidad en los próximos años.

The study of movement is central to ecological analysis at the gene, individual, population, community and ecosystem levels. DNA markers are very useful tools for the study of movement at all these levels, allowing, for instance, the determination of population origin of migrants, the study of mating systems, the quantification of the scale of interspecific interactions, or the characterization of dispersal and competence spatial patterns. At the gene level, DNA markers are necessary to study genetic structure and gene flow within and among populations, and to study their combined effects with other evolutionary forces and biotic and abiotic factors on local adaptation. We review in this paper some DNA-marker methods of potential utility in movement ecology, identifying study areas where they are expected to be especially useful during the next years.
