| Abstract: |
| This study examines competition models based on the Lotka--Volterra form that incorporate starvation-driven diffusions (SDD). Such dispersal assumes that species adjust their dispersal according to the abundance or scarcity of resources in a heterogeneous habitat. The primary objective of this study is to examine how SDD, in combination with diverse interspecific interactions, affects species` fitness and coexistence states. To this end, the study introduces a refined classification for competing interactions based on a novel metric that quantifies the variability of resource heterogeneity across the environment. This approach contrasts with traditional models that assume uniform diffusion within homogeneous environments. The study reveals that the interplay between species` dispersal strategies and the varying intensities of interspecific competition significantly impacts ecological outcomes. |
