Factors leading to insect diversity in Hawaii
|
extreme isolation with in-situ diversification
evolution on a conveyor belt islands within islands ecological specialization, morphological diversity |
|
|
Habitat degradation leading to decrease in diversity
|
alien species, development, natural disaster
pest control competition w/ alien species predation from alien arthropods |
|
|
Assess connectivity btwn proposed conservation management units
|
rates of migration/gene flow
|
|
|
Islands a dead-end for species
|
no, drosophilia have shown that they have been able to "escape" based on lineage
|
|
|
Conveyor Belt
|
pattern of older taxa on older islands and younger species on younger islands
picticornis planitibia neopicta cyrtoloma |
|
|
Population Genetics - most populations are how large
|
estimate for Ne for each species range from 10^5-10^6
|
|
|
Island Biogeography
|
dispersal common over geological time
gene flow/ dispersal btwn island pop varies in-situ diversification is common younger islands have younger species than neighboring older ones island lineages can colonize continents |
