Passage:
In evolutionary ecology, the phenomenon of "trophic decoupling latency" describes a systemic vulnerability that arises when an obligate predator species and its primary prey rely on different environmental cues to regulate their seasonal lifecycles. Typically, the predator species relies on photoperiodism—invariant photoperiod cues such as day length—to trigger its reproductive cycle, whereas the prey species responds directly to ambient thermal shifts to initiate breeding and emergence. During periods of rapid climatic warming, the prey species advances its lifecycle earlier in the spring, decoupling the timing of maximum prey availability from the peak nutritional demands of offspring predator rearing.
Crucially, the ecological impact of this temporal mismatch is not immediately apparent in overall predator abundance. Because adult predators possess sufficient metabolic resilience to survive the seasonal food deficit, adult mortality rates remain baseline in the short term, masking the underlying crisis. However, because newly hatched offspring suffer near-total mortality due to the absence of synchronized prey, recruitment into the breeding population halts entirely. Consequently, the predator population maintains a deceptive numerical stability for several years until the aging adult cohort reaches natural senescence, at which point the population experiences a sudden, irreversible collapse without prior warning signals.
Which of the following scenarios is most analogous to the phenomenon of "trophic decoupling latency" as described in the passage?
- A legacy software enterprise maintains stable annual revenue because existing corporate clients are bound by multi-year service contracts, but its failure to adopt modern integration standards prevents it from acquiring new subscriptions, resulting in an abrupt financial collapse once the legacy contracts expire.Cevap
- BAn arctic wildlife reserve experiences a sharp, immediate drop in predator populations after an unusually warm winter causes melting sea ice to alter the regional migration routes of migratory prey species.
- CA manufacturing plant suffers an immediate drop in output following a raw material supply disruption, but its long-term viability increases after it successfully recruits a new generation of skilled technicians.
- DA commercial airline experiences gradual declines in passenger volume over a decade due to aggressive market competition from high-speed rail, prompting incremental downsizing of its operational fleet.
- EA research university department increases its faculty hiring based on optimistic projections of student enrollment, but is forced to trim administrative staff when actual applicant numbers fall below historical averages.
