Biogeographical and Ecological Patterns of the Bryophytic Flora Inhabiting the Small Islands Surrounding the Italian Peninsula, Sicily and Sardinia

Area of Science:

• Ecology
• Botany
• Bryology

Background:

• Bryophytes are adaptable colonizers crucial to terrestrial ecosystems.
• Their autoecology, especially on Mediterranean islands, is poorly understood.
• Bryophytes serve as unique models for studying plant adaptation and stress resistance.

Purpose of the Study:

• To evaluate bryophyte diversity on islands surrounding the Italian peninsula, Sicily, and Sardinia.
• To analyze how ecological variables (area, insularity, altitude, substratum) influence bryophyte species richness and diversity.
• To describe the ecological and functional traits of Mediterranean bryophytes in relation to island features.

Main Methods:

• Floristic surveys on selected Italian islands and islets.
• Statistical analysis of ecological variables (area, insularity, altitude, substratum).
• Application of ecological indicators for functional trait assessment of bryophyte species.

Main Results:

• An updated overview of bryophyte floristic richness and diversity on small Mediterranean islands.
• Identification of key ecological drivers shaping bryophyte communities.
• Demonstration of island-specific floristic and ecological differences.

Conclusions:

• Island geographical and environmental features significantly influence bryophyte diversity and ecological characteristics.
• Understanding these drivers is crucial for bryophyte conservation in Mediterranean ecosystems.
• This study provides insights into the autoecology of Mediterranean bryophytes on islands.
