Background and Study Site
• 1969 – Galt & Galt (Econ. Bot.) conducted an ethnobotanical study in Khamma
• 45 years later, we investigate how TEK and practice has changed
Specchio di Venere
Pantescan Gardens
Olive groves
Zibibbo grapes: passito wine
Caperi
Capparis spinosa subsp. rupestris (Sm.) Nyman, Capparaceae
Lactic-acid fermentation of the flower buds in salt to make capers!
Methods • PIC of community governance
and individuals • 42 informants
▫ age ranged from 28-90, with a median age of 64 and gender distribution of 59.5% male and 40.5% female
• Free-listing and semi-structured interviews complemented with a booklet composed of photos of 28 fungi and 93 plants
• Data analysis based on informant consensus factor, free-listing percent measure, fidelity levels, and use-value citation index
Results • Galt and Galt (1978) documented 107 specific uses of
local botanical taxa • Of these, 45 were not quoted by any informants in
our 2014 survey, representing a loss of 42% of the uses documented 45 years ago
• An additional 235 specific uses of local flora and fungi were recorded in the present work, which were not included in the original study.
• A total of 95 plant taxa and 17 fungal taxa, representing 44 and 9 plant and fungal families, respectively, were cited by the study participants.
• Data on 2,124 use citations were collected, representing a total of 297 distinct sets of communal knowledge regarding specific taxa
Informant Consensus Factor
𝐹𝑖𝑐 =𝑁𝑢𝑐 −𝑁𝑡𝑁𝑢𝑐 − 1
• Nuc : total number of use citations in each category
• Nt : number of taxa used in that category
• High Fic values (near 1.0) are obtained when one or a few species are reported to be used by a large proportion of informants for a particular category, whereas lower Fic values indicate that informants disagree over which taxa to use

Conclusions
• TEK concerning wild foods, household uses and ethnoveterinary applications is widespread
• Wild plants and fungi still collected and eaten
• Knowledge, but not practice, of historic maritime applications (e.g. fish poisons, boat construction, fiber dyes)
• Loss of detail in plants used in spiritual healing (e.g. use of Ruta chalapensis)
Acknowledgments
• Funding support provided Emory University Center for the Study of Human Health.
• We would like to extend our heartfelt thanks to the Commune of Pantelleria and all Pantescan communities and people who agreed to participate in this study.
• We also thank Marco Caputo for assistance with field collection of voucher specimens.
