WebOct 26, 2016 · Changing population sizes through time, selection, and gene flow/migration will affect coalescence, altering the picture given by the neutral model and complicating the application of this approach. WebOct 26, 2024 · Habitat loss and fragmentation are among the biggest threats to biodiversity. Anthropogenic habitat fragmentation leads to small and isolated remnant plant and animal populations. The combination of increased random genetic drift, inbreeding, and reduced gene flow may substantially reduce genetic variation of remnant populations.
