Resumen

Los estudios sobre la presencia de residuos antropogénicos en el mar y su ingesta por aves marinas se han incrementado en las últimas décadas. Los Procellariiformes son particularmente susceptibles a la ingesta de plásticos debido a que se alimentan preferentemente de presas sobre la superficie del mar, donde los plásticos tienden a flotar y acumularse. Luego de una extensa revisión bibliográfica y la aplicación práctica de técnicas en el laboratorio y el campo, presentamos protocolos estandarizados para la colecta de muestras para evaluar la ingesta de plásticos en Procellariiformes. Estos protocolos sugieren una variedad de tipos y fuentes de muestras y metodologías de colecta de acuerdo a diferentes objetivos de investigación. Las muestras pueden ser colectadas de aves muertas encontradas en la playa o capturadas incidentalmente en pesquerías; de aves vivas o muertas en colonias reproductivas y centros de rehabilitación; o de manera no-invasiva en el caso de fecas, bolos y huevos no eclosionados. Además, recomendamos métodos de análisis, insumos necesarios y rutinas de limpieza para evitar la contaminación durante la colecta y procesamiento de muestras. La implementación de protocolos estandarizados para la colecta y el análisis de muestras favorece la consistencia y repetibilidad de los estudios, permitiendo la comparación de los resultados y la detección de patrones espacio-temporales a gran escala.
