Abstract

fetched live from OpenAlex

Studies of ecosystem responses to climate change often focus on potential equilibria in species or community distributions, overlooking the transitions to new equilibrium states. Transient phases can however last for decades or centuries, during which both demography and interspecific interactions are expected to play a crucial role. Here, we investigate the response of vegetation to climate warming at high latitudes involving a shift from open vegetation to either boreal (mainly coniferous) or temperate (mainly deciduous) forests. We specifically address how interactions among browsers and vegetation could affect the shift in dominance of vegetation type after climate warming. We characterize the transient dynamics using five measures: 1) asymptotic resilience, i.e. the rate at which equilibrium is restored, 2) initial resilience, the short‐term rate of change of the ecosystem after climate change, 3) ecosystem exposure, i.e. the shift of the equilibrium due to climate change, 4) sensitivity, or the time to recover equilibrium, and 5) vulnerability, measured as the cumulative amount of changes in vegetation states during the transient phase. We find that plant–herbivore interactions usually extend the length of the transient period and induce more cumulative changes in vegetation types. This result implies that the consideration of multiple interacting species is necessary to provide robust scenarios of how ecosystems will respond to global changes. We furthermore show that plant–herbivore interactions disrupt the correlation between the five measures characterizing the transient dynamics, highlighting the need for a full multidimensional characterization of transients.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
