Biodiversity, Redundancy, and Ecological Function
Biodiversity, redundancy, and ecological function are central to resilience because living systems persist through disturbance not by relying on a single species, pathway, or mechanism, but through overlapping forms of life, function, response, memory, and repair. Biodiversity includes genetic diversity, species diversity, functional diversity, response diversity, habitat diversity, trophic diversity, microbial diversity, and the ecological relationships that allow systems to regulate, regenerate, adapt, and reorganize under changing conditions. This article explains why redundancy is not waste but ecological insurance, why functional diversity matters more than simple species counts, and why response diversity becomes essential under climate uncertainty. It connects biodiversity to ecosystem services, food webs, soil systems, genetic adaptation, landscape connectivity, disturbance recovery, governance, justice, and the practical modeling workflows needed to study ecological resilience responsibly.
