Sažetak
Coralligenous outcrops are an important “hot spot” of Mediterranean biodiversity. Most of the benthic species inhabiting these outcrops are long-lived and slow-growing, thus making them especially vulnerable. The interaction between the climatic changes projected for the 21st century and other ongoing human-induced stressors, presents a major challenge to its biodiversity. Accurate studies on biodiversity over time and large spatial scales are thus required to know its current patterns, to detect changes, and to furnish predictions in developing future scenarios of biodiversity. Here, we present data from an ongoing study to estimate the diversity of macro-species of algae and invertebrates (mainly sponges, cnidarians, bryozoans and tunicates) through photographic surveys across large spatial (~36º- 43º latitude, > 1000 Km) and temporal scales (5 years). We used a hierarchical sampling procedure to measure species richness among regions, localities within regions, and sites within localities as a standardized monitoring network. The combination of large spatial and temporal approaches of this study provides an important baseline against which future effects of disturbances (e.g. warming- induced mortalities, invasive species, dramatic storms) can be assessed. Furthermore, the need for local to regional-scale biodiversity metrics and measurements, are crucial to document and assessing changes in marine biodiversity.
