Document Summary
Urbanization- how humans alter landscapes- particular cities. Alae ula- endangered wetland bird: endemic rallid (species, specialize on low elevation coastal wetlands, small, fragmented populations (habitat fragmentation, wetlands- particular in hawaii. A majority of these have been destroyed hence a major reason for their endangerment. Where we want to build cities- flat, ocean view, abundance of water. Invasive species- mongoose, ferrell cats (birds are not used to having predators) Invasive plants- destroy habitats that they rely on. Habitat connotation- if habitats interact with one another, they will be better off: opposite of habitat fragmentation. Research methods: mark birds, keep track of where the birds are, looking at the genetics of the birds- are the genes shared in the different habitats. Species will often move to breed: tracking device that emits radio waves. Surrounded by high density urbanization urbanization is preventing the flow of different species.
