MAF biodiversity measurements: Species, ecosystem, and genetic

<ns3:p>Biodiversity operates across multiple levels of biological organization, encompassing genes, species, and ecosystems. It plays a crucial role in sustaining ecological resilience and delivering essential services such as food and clean water. Higher biodiversity enhances the ability of ecosystems to withstand and recover from disturbances. Monitoring biodiversity is therefore vital for assessing ecosystem health, identifying imbalances, and preserving these critical services. Within the oceanic ecosystems, Marine Animal Forests (MAFs), structured by key organisms like corals and sponges, serve as biodiversity hotspots and play a vital role in regulating oceanic processes. This paper explores methodologies for studying MAFs across three levels: intra-species diversity, species diversity, and genetic diversity. Intra-species diversity focuses on variation within and between individuals, with an emphasis on phenomena like chimerism and somatic mutations. Species diversity is analyzed using taxonomic, functional, and biotic indices, while genetic diversity is examined through DNA barcoding, species delimitation analyses (SDA), metabarcoding, and microsatellite markers. Although each method provides valuable insights independently, integrating them can significantly enhance the speed and effectiveness of biodiversity assessments. Future efforts should emphasize public engagement through citizen science, ensuring biodiversity monitoring tools become more accessible, affordable, and user-friendly. Additionally, expanding server infrastructure will be key to accelerating bioinformatic workflows. Finally, strengthening global collaborations and increasing awareness of biodiversity and climate change remain essential priorities.</ns3:p>
