【Abstract】 Invasive species and population pose major threats to biodiversity,ecosystem integrity,agriculture,fisheries,and public health.The rapid spread of exotics has received considerable attention within the international community,and has mobilized substantial ecological research.Ecological invasions present interesting evolutionary problems because they are stochastic events often involving small populations that can survive rapid habitat transitions.For example,natural selection and genetic variance,hybridization and environmental interaction,the role of particular genes and genomic rearrangements.更多还原
