Question

Review the following summaries of two informational sources regarding ecological monitoring in Ecuador's Chocó Andino Biosphere Reserve:

Source 1 (Audio Broadcast: Radio Pichincha Interview)
In a radio interview, community conservation coordinator Elena Morales explains how local parish cooperatives use automated acoustic recording units deployed throughout forest canopies. Morales emphasizes that organized youth patrols conduct bi-weekly field visits to physically inspect hardware, replace memory cards, and ground-verify wildlife observations. She notes that bioacoustic data clearly demonstrate a measurable rebound in threatened bird species vocalizations within restored biological corridors. Furthermore, Morales underscores that while ecotourism generates modest supplementary revenue, traditional agricultural farming remains the primary economic foundation for local families.

Source 2 (Print Article: Andean Ecology & Conservation Review)
An empirical study evaluates forest regeneration metrics across the Chocó Andino cloud forest. The authors analyze continuous acoustic sensor recordings, documenting a statistically significant increase in avian vocalization diversity and frequency across regenerating secondary forest sectors. The study introduces complex statistical soundscape indices to quantify high-frequency canopy acoustic activity across specific elevation gradients. Additionally, socioeconomic survey data in the report indicate that agricultural cultivation continues to be the dominant source of household income, with ecotourism functioning only as a secondary financial stream. The researchers focus exclusively on computational telemetry algorithms and make no mention of community youth maintenance patrols.

Match each claim on the left with its corresponding corroboration status across the two sources on the right.
