Resumen
En las últimas décadas, la degradación ambiental de los ecosistemas se ha acelerado a un ritmo sin precedentes. El cambio climático global y la alteración de los hábitats naturales han repercutido negativamente tanto a la biodiversidad como al bienestar humano. A través de los últimos milenios, los ecosistemas han enfrentado cambios similares asociados con distintos modos de variabilidad climática y diversos patrones de ocupación humana. Así, el estudio del pasado sirve como referencia para entender el funcionamiento del sistema terrestre en el presente. En este contexto, la recuperación y análisis de registros sedimentarios que permitan la identificación de condiciones ambientales de línea base son fundamentales. En este sentido, la nucleación por pistón es una técnica eficiente y confiable para extraer paquetes sedimentarios sin dañar la integridad de los sedimentos. En este artículo, exploramos las ventajas de nucleación por pistón, y mostramos, a través de un video, la metodología detallada para llevar a cabo la recuperación de secuencias sedimentarias usando un nucleador de pistón Livingstone modificado en ambientes lacustres.
