Primate Conservation: Primates on the brink... Slide 2 Some facts... 80 million or more plants and animals make up worlds biodiversity Over half of these species are found in tropical rainforests Tropical rainforests make up only 7% of the worlds surface Extinction rate= 137+ species/day Slide 3 Rates of deforestation Slide 4 Vary by habitat Madagascar, Thailand exampleThailand example Patterns of forest loss (severe for future) See Figure 8.2 (coursepak reading) Rates are not slowing down. Slide 5 Habitat destruction Mostly due to anthropogenic disturbance (human induced) (table 8.1) Agriculture mainly (fires) Wood extraction (selective logging) Mining, hydroelectric plants Slide 6 Agriculture Permanent or shifting (rice, beans, coffee) Slide 7 Leads to slash and burn http://earthobservatory.nasa.gov/Observatory/Datasets/fires.avhrr.html Global fires Slide 8 Forestry Slide 9 Other forest products Slide 10 Mining and Hydroelectric plants Petroleum camp, Africa Near mining camp, SE Asia Slide 11 What happens... Obvious removal of forest area Creates fragmented habitat Limits dispersal Increases exposure (wind, fire) Slide 12 What happens... Selective logging Impacts surrounding trees Creates light gaps Fishbone pattern allows for inroads into more pristine forest Removes large patches- Figure 8.3 Slide 13 Hunting Hunting pressures on animals increases Primates favored (Figure 9.1) But varies- Asia/Madagascar low, higher in New World/Africa (table 9.2) Slide 14 Types of Hunting Trapped or shot Impact on population will depend on area Extinction...
