This dichotomy raises the question of whether present day range shifts in response to anthropogenic climate change are uniform (as predicted by theory and readily assumed) or multidirectional (as empirically observed in the past).

With this approach, life stage serves as a <i>proxy</i> for time, in which we assume each life stage represents a different <i>establishment</i> time on the landscape, thereby snapshotting a species' range at three discrete, past timesteps. For each species, we quantify a range shift as a change in range size, position, and direction between all life-stage comparisons (e.g., <i>adult to sapling</i>).

For many traits—especially those with weak phylogenetic signal and sparse empirical data—these estimates tend to perform no better than a trivial baseline such as the mean of the observed values. Even when phylogenetic signal is non-negligible and overall imputation performance is acceptable, improvements at the level of individual estimates are often modest. When used uncritically, such estimates can distort ecological patterns, mislead conservation priorities, and propagate errors across a wide range of downstream applications.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Guiding Principles for Imputation</h3>\u0000 \u0000 <p>We propose two complementary strategies: (1) prioritising targeted empirical data collection, guided by tools such as phylogenetic ignorance maps to identify critical data gaps, and (2) adopting multiple phylogenetic imputation as a probabilistic framework that quantifies and propagates uncertainty into downstream analyses. We provide practical recommendations for implementing such an uncertainty-aware workflow, including procedures for assessing how the expected accuracy of phylogenetic estimates varies across individual missing values.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Trait-based science must move beyond the illusion of completeness.
