The paper shows that repulsion from slow-diffusing nutrients enhances chemotaxis towards moving nutrient sources in E. coli by combining attraction to fast-diffusing nutrients.

The paper shows that complex ecosystems become unstable when resource consumption deviates from niche ranges, leading to alternative states and species extinction.

The paper shows that structured interactions in microbial communities prevent keystone species by enhancing resilience to extinctions in synthetic microcosms.

The paper shows that sequential resource use and environmental changes create temporal niches, allowing more species to coexist than resources alone.
