  6. Equilibrium Theory of Island Biogeography R. H. MacArthur E. O. Wilson

  7. Freeport-McMoran Mine, Irian Jaya, New Guinea

  8. Conservation Biology Value of Biodiversity Hot spots of diversity SLOSS debate, Design of Nature Reserves Minimum viable population size Genetic bottleneck Population viability analysis Sensitivity analyses of Leslie matrices “Extinction vortex” Habitat loss, habitat fragmentation, small population size, genetic and demographic stochasticity Toxic pollution and climatic changes

  9. Different types of metapopulations

  10. Aldo Leopold: “A land ethic changes the role of Homo sapiens from conqueror of the land community to plain member and citizen of it. It implies respect for his fellow-members and also respect for the community as such.”
