Marine Biodiversity research that can be also be applied

Phylogenetic Diversity Fisheries Management

SeaKeys FBI Small Grants Programme

Single or multiple stocks of kingklip?

• Study based on mtDNA and nine microsatellites
• One or two stocks implications for management
• Analyses suggest two stocks with high gene flow
• Requires separate management of west coast and east coast stocks

and will have implications for the overall exploitation of stock

Phylogenetic diversity and species richness of marine taxa

• Diverse range of taxa; nudibranchs, chitons, sparids
• Examined phylogenetic diversity (PD) and

species richness patterns (SR)

• Allows the inclusion of evolutionary processes into spatial planning

SR PD PD vs SR suggest that using SR underestimates conservation prioritisation - esp along the west coast

Contribution to biodiversity mapping and barcoding

20 sampling localities from Port Nolloth to Sodwana >450 specimen records Potential for 180 barcodes Heavily involved with citizen science New species, old species that are new species, taxonomic madness! Exploring speciation, colonisation and biogeography, ecological and phylogenetic overlap Potential for many, many papers arising from her work
