Species data and Cerrado KBAs Cristiano Nogueira, Dr. Sc. Biodiversity analyst – CI Brasil - Cerrado program
Cerrado 60-70s Wilderness area Hotspot ~20% original habitats Extremely fast rates of habitat destruction ~ ha lost every month (Machado et al. 2004) Emas National Park ~ ha Jalapão State Park ~ ha
Cerrado High richness and endemism in vascular plants - ~44% of over spp.
Cerrado vertebrate fauna: Traditional view: Species poor (Vanzolini, 1963; Sick,1965) Low endemism levels (Vitt, 1991; Vanzolini, 1976; Redford & Fonseca, 1986; Silva 1997) Richness concentrated in forested habitats (Redford & Fonseca, 1986; Silva 1997)
Cerrado vertebrate diversity: Recent compilations : Small mammals (Carmignotto, 2004) Squamate reptiles (Nogueira, 2005, 2006) Museum data + literature records + standardized field samplings (10 localities for squamates)
Endêmico, sul Endêmico, norte Endêmico, central Endêmico oeste, pontual
Cerrado vertebrate diversity: New evidence: Squamates and small mammals High richness High endemism levels Habitat specialists - grasslands/cerrados/forests Richness and endemism concentrated in open habitats Wide regions still poorly sampled Survey gap analysis (Funk et al., 2005)
Lack of basic data Squamate reptiles Nogueira, 2005
Rodents and marsupials Carmignotto, 2004
Results: Squamate reptiles Endemism/Richness <24/<120 (20%; Myers et al. 2000) 31/186 (16%; Colli et al. 2002) 83/236 (35%; Nogueira, in prep.)
Results: Data incorporated into ongoing revision of Cerrado/Pantanal prioritary areas workshop (12-14 july 2006, Brasilia, Brasil) Herpetofaunal target species: 63 (1998; first workshop) 248 (2006, first revision, underway) Regional threatened species lists- Pará, Minas Gerais and Goiás states
Cerrado KBAs taxonomic database Criterion 1 (Eken et al. 2004) : 46 threatened species (IUCN 2004) (includes all Cerrado threatened taxa) Is this enough?
Criterion 2 (Eken et al. 2004) Restricted range (< km 2 ) – 75 taxa: Small mammals Squamate reptiles Annual fishes (Teleostei: Rivulidae) Vulnerability - Many fit VU A4c. Overlooked in threatened species lists (IUCN or IBAMA) Irreplaceability
Criterion 2 (Eken et al. 2004) Restricted range Biogeographic pattern Speciation Evolutionary process
Criterion 2 (Eken et al. 2004) Restricted range (< km 2 ) – Critical further steps: Urgent new compilations for Amphibians Freshwater fishes Large mammals Vascular plants 3-4 years span – partnership with key herbaria and museums – graduate students (UnB, MZUSP, UNICAMP, MPEG). Cheapest (~2%), but crucial, part of the KBA process
