In ecological management, "assisted migration"—the intentional relocation of species to habitats outside their historical range to protect them from climate disruption—frequently triggers unexpected ecological imbalances. When a predatory beetle species native to cooler northern forests was introduced into a temperate Southern pine reserve to control an invasive bark-boring pest, resource management officials assumed the beetle would restrict its diet to the target pest. However, the introduced beetle quickly adapted to prey upon a vulnerable native moth species that occupied a similar ecological niche, ultimately causing a sharp decline in local pollination networks. Conservationists refer to this failure mode as a "niche-overlap spillover," occurring when an introduced intervention agent unexpectedly expands its scope to harm a non-target native species due to structural or functional similarities between that non-target species and the intended target. Consequently, recent ecological guidelines demand that prior to authorizing any assisted migration program, managers must perform comprehensive ecological vulnerability assessments to evaluate non-target species sharing functional traits with the target pest.
Based on the passage, which of the following scenarios is most analogous to the "niche-overlap spillover" mechanism described by the author?
- A security software designed to quarantine a specific strain of financial malware accidentally disables a crucial system administration tool because the legitimate tool shares structural coding architecture with the malware.Answer
- BA pharmaceutical firm manufactures an anti-inflammatory drug, but the medication proves ineffective in clinical trials because patients metabolize the active compound too quickly.
- CA retail company launches a marketing campaign targeting young adults, but the campaign unexpectedly lowers sales among older customers who dislike the new branding tone.
- DAn agricultural technology firm develops an automated weeding machine that fails because the targeted weeds rapidly evolve resistance to the machine's mechanical cutting blades.
- EA municipal government constructs a bypass road to relieve downtown traffic congestion, but total vehicle volume increases citywide as more residents relocate to suburban areas.
