| Abstract | Individual movement is critical in shaping population dynamics. However, theoretical frame-works linking these two processes often make unrealistic assumptions about how animals move or, when attempting to incorporate realistic movement patterns, must rely on numerical simulations. To address this gap, we introduce the range-resident logistic model, which is an easy-to-simulate and mathematically tractable extension of the spatial logistic model that incorporates empirically supported range-resident movement. Our framework unifies previous non-spatial and (sessile) spatial formulations of the logistic model as limiting cases, recovering these two limits when home ranges are infinitely large and vanishingly small, respectively. Interpolating between these two regimes, the long-term population size depends nonlinearly on home-range size and spatial distribution. Neglecting range residency can hence lead to significantly under- or overestimating population carrying capacity. To better understand these results, we also introduce a novel crowding index that depends on movement parameters and can be estimated from tracking data. This index captures the influence of spatial structure on population size, and serves as a robust predictor of abundance. The range-resident logistic model is thus a unifying framework bridging movement and population ecology, and provides new insights into how different patterns of individual space usage shape intraspecific interactions and regulate population growth. |
