A Master’s thesis completed at the Biology Department of the University of Crete within the framework of the EFFECTIVE project has provided new insights into the biodiversity associated with the endemic Mediterranean coral Cladocora caespitosa in the Kavo Gkreko Marine Protected Area (Cyprus). 

The research, conducted by MSc student Nikol Mode, investigated the composition and abundance of meiobenthic communities inhabiting coral reefs and adjacent habitats. Sampling took place during October 2024 and March 2025 at two coral reef stations (Vasiliki and Kryo Nero) and a control station without corals (Blue Lagoon). 

The study identified 20 meiobenthic taxonomic groups and revealed higher organism abundances in coral-associated habitats, while sponge samples supported the highest biodiversity. Community composition differed among sites, highlighting the influence of local environmental conditions and habitat heterogeneity. 

The results demonstrate that meiobenthic communities are highly sensitive bioindicators of environmental quality and ecosystem functioning. These findings provide valuable information for monitoring restoration actions and assessing ecological status within Marine Protected Areas, supporting the broader objectives of the EFFECTIVE project. 

The study was conducted within the framework of EFFECTIVE Pilot 4 through collaboration between HCMR and CMMI, demonstrating how the project supports both scientific research and the training of early-career marine scientists. 

Congratulations to Nikol Mode and the HCMR and CMMI teams for this valuable contribution to Pilot 4 and to the scientific understanding of Mediterranean coral reef ecosystems.
