Resumen

La influencia humana en los ecosistemas y las interacciones entre especies han sido observadas en variados estudios ornitológicos. Este fenómeno es evidente en áreas donde se proveen alimentos a diferentes comunidades de fauna, como en los comederos de colibríes. Esta suplementación artificial de recursos plantea preguntas sobre su impacto en aspectos como la polinización, visitas florales y movilidad de los colibríes. A partir de una revisión sistemática de literatura se realizó la identificación de los posibles cambios y/o efectos que la presencia de bebederos artificiales podría tener sobre la relación polinizador-planta. Se identificaron 26 artículos que mencionan temas sobre bebederos y su rol en la interacción planta-animal, catalogando los posibles impactos como positivos, negativos o neutros (sin impacto). Se encontró una baja producción científica sobre el tema, donde no fue posible determinar si hay un impacto claro a causa de los bebederos. Adicionalmente, varios investigadores afirman que algunos de los efectos e interacciones de los bebederos en la relación planta-animal podrían estar asociados a un efecto especie-específico, por lo que las generalizaciones son inadecuadas. La literatura de soporte es insuficiente y no concluyente, resaltando la necesidad de estudios rigurosos para evaluar cómo los comederos pueden afectar la biología reproductiva, la distribución espacial y los procesos ecosistémicos de los colibríes a diferentes escalas y aspectos como la biología reproductiva, la distribución espacial de los colibríes y sobre la modificación de procesos ecosistémicos. Complementariamente, se hizo una búsqueda por Google® para identificar páginas de difusión masiva que den información al público en general; de los resultados se tomaron las 40 primeras páginas y sobre ellas se indagó con relación a las fuentes que sustentaban la información planteada, encontrando un vacío de fuentes verificables, como artículos científicos. Consideramos fundamental impulsar la idea de que la divulgación de información de dominio público debe de ser en mayor medida sustentada por datos y estudios ornitológicos concretos.
