Species data and Cerrado KBAs Cristiano Nogueira, Dr. Sc. Biodiversity analyst – CI Brasil - Cerrado program
2
Cerrado 60-70s Wilderness area 2000- Hotspot ~20% original habitats Extremely fast rates of habitat destruction ~166.000 ha lost every month (Machado et al. 2004) Emas National Park ~130.000ha Jalapão State Park ~138.000ha
3
Cerrado High richness and endemism in vascular plants - ~44% of over 11.000 spp.
4
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)
5
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) 1996-2005
7
Endêmico, sul Endêmico, norte Endêmico, central Endêmico oeste, pontual
8
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)
9
Lack of basic data Squamate reptiles Nogueira, 2005
10
Rodents and marsupials Carmignotto, 2004
11
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.)
12
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
13
Cerrado KBAs taxonomic database Criterion 1 (Eken et al. 2004) : 46 threatened species (IUCN 2004) (includes all Cerrado threatened taxa) Is this enough?
14
Criterion 2 (Eken et al. 2004) Restricted range (< 50.000 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
15
Criterion 2 (Eken et al. 2004) Restricted range Biogeographic pattern Speciation Evolutionary process
16
Criterion 2 (Eken et al. 2004) Restricted range (< 50.000 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
