“THE FORGOTTEN POLLINATORS”: FILLING A BIODIVERSITY INFORMATION GAP

Jonathan F. Colville Applied Biodiversity Research, SANBI

South Africa’s Terrestrial Biodiversity: •World renowned flora! •Well studied and appreciated:

•Floral Kingdoms, Biomes and vegetation mapping •Floristic hotspots –richness and endemism •Red data listings •Extensive National Database (PRECIS) •Rapidly accumulating phylogenetic data •Strong cohort of taxonomists •Conservation strategies strongly influenced

•World renowned Fauna! •Vertebrates - Roar!!! •Invertebrates although appreciated…

•Less well-known! •Less well-studied! •Above categories currently not available!!!

•However, Insects can be considered as the very glue that holds earth’s ecosystems together! •And yet we neglected this key component of biodiversity!

“…if ants, bees, and termites alone were removed from the earth, terrestrial life would probably collapse…” (Grimaldi & Engle 2005)

Biodiversity Information Gap for Inverts and Insects: •What do we know? •SA has remarkably rich and unique diversity:

•Gondwanan and Relictual component (800 sp., 600 genera, 200 families, 41 orders) •Wide-spread groups, but which have their centre of diversity and adaptive radiations in SA •High richness and endemism!

Nemestrinidae

Larvae??

tabanidae

Hump-Backed Flies

Mydas Flies

Bee Flies

Lacewings

Bladder Grasshoppers

Cederberg giant katydid

Biodiversity Information Gap for Inverts and Insects: •What do we NOT know? •Very limited baseline data on where species occur and their concentrations…?! •Spatial data is key! •Is there data available? •YES! •Collate data from natural history collections, literature, and taxonomic experts…

Monkey Beetles: 1500 sp. •Endemism: 98% of species

Bees: >1200 sp. •Endemism: >85% of species

Filling the Gap: •Target groups that have:

•high conservation value (richness and endemism) •Ecologically NB (e.g. pollinators) •taxonomically well-know •have well-sampled and curated collections •E.g. Fruit Chafer beetles…

Mawdsley et al. 2011

Biologically important group: •NB Pollinators (Protea spp., Acacia spp., Orchids, Asclepiads)•Ecosystem Services! •Fruit feeders (some pests!) •Larvae NB detritivores in soil • Biological interactions:

•Ants, termite, beehives, wasp nets, rock hyrax) •Many rare and endemic taxa •Threats from:

•habitat loss, illegal collecting, etc.

Peter & Johnson, 2010. SA J. of Bot.

Building the Fruit chafer dataset: •Linking:

•Natural history collections •Taxonomists •Museum Curators •Existing database structure (e.g. Access) •Training student data capturers and Interns

Institute No. of Specimens (No. of SA taxa)

Percentage Specimens digitised

Percentage of records geo-referenced

Strengths

SANC 8500 (143) 100 98% •Well-curated and identified (Erik Holm, Riaan Stals). •Second largest collection in SA

Iziko Museum 2558 (165) 100% 95% Good collection, especially for Cape taxa

Ditsong Transvaal National Museum

20 000 (250) 100% 96% •Well-curated and identified (James Harrison). Largest collection in SA

Natal Museum 380 (40) 100% 100% Small collection, but valuable
