Biodiversity, Biogeography and Endemism Flashcards
Mt Kinabalu, 90% of 750 orchids endemic
Wood et al 1993
species richness negatively correlated with amplitude of past climatic change
Jansson 2003
limited plant dispersal in tropic allows inferior competitors to persist
Hurt et al 1995
SE Asia 4% of Earth’s surface, 25% of species
Sodhi et al 2006
25 worldwide biodiversity hotspots (endemism + threat)
38% already ‘protected’
$500m pa to protect
SE Asia 44% plants, 35% verts
Myers et al 2000
$300 trillion in subsidies to environmentally destructive industries
Myers et al 1993
90% of last million years, SE Asia landmass 1.5-2x bigger
62m sea level lower
biogeographical regionalism
Woodruff 2010
species:area relationships important for small islands (sea level rise)
Okie and Brown 2009
Glacial refugia
RF retreated to borneo hills
RF turned to savannah plains
Morley 2000
SE Asia climate prediction for 2100
Bickford et al 2010
tropical species adapted to limited seasonal variation
already close to thermal limit
may be limited from cooler refugia
Wright et al 2009
many birds already expanded to highest elevation limits
Peh 2007
Species responses to climate change depend on:
dispersal ability
niche breadth
ecological plasticity
Parmesan 2006
