Biodiversity constitutes the foundation of ecological balance and of the services that sustain human life, making its study and conservation fundamental in a context of increasing anthropogenic pressure and climate change. Research in this field has been oriented toward understanding diversity at multiple scales and designing effective conservation strategies. This review article aims to analyze the foundations of biodiversity and its conservation, the importance of genetic, species, and ecosystem diversity, as well as the role of ecological succession in the dynamics of biological communities. It argues that biodiversity, in all its dimensions, ensures resilience and ecosystem functionality, while succession provides the conceptual framework for understanding changes in community composition over time. The review asserts that the loss of diversity at any level weakens the adaptive capacity of natural systems and that successional processes are key to restoration and adaptive management. It concludes that integrating multiscale approaches to biodiversity with an understanding of successional dynamics is essential for designing more effective, sustainable, and adaptive conservation strategies in the face of global change scenarios.
