Listen to the following excerpt from an interview between an environmental journalist and Dr. Valeria Morales, an urban ecologist:
Journalist: "Many municipal governments are replacing conventional high-intensity streetlights with narrow-spectrum amber LED fixtures to protect nocturnal insects. Does this spectral transition sufficiently resolve the decline of urban pollinator populations?"
Dr. Morales: "While amber wavelengths substantially reduce phototactic disorientation for moths and beetles, our multi-year field surveys reveal that high-altitude rooftop green spaces remain genetically isolated. Unless municipalities construct continuous, ground-level vegetative corridors that physically link these elevated microhabitats, mitigating light toxicity alone will not yield self-sustaining reproductive cycles."
Based on Dr. Morales's statements, which of the following conclusions can be drawn regarding urban pollinator conservation?
- AIsolated rooftop gardens provide adequate reproductive connectivity once phototactic disorientation from streetlights is eliminated.
- BThe journalist argues that narrow-spectrum lighting is detrimental, whereas Dr. Morales considers it the single most crucial conservation measure.
- Adjusting municipal lighting wavelengths is insufficient on its own without contiguous physical vegetation connecting fragmented urban habitats.Cevap
- DMunicipalities should phase out rooftop gardens entirely because ground-level vegetation is the only viable environment for nocturnal insect breeding.
