africanization in the united states: replacement of feral european honeybees (apis mellifera l.) by an african hybrid swarm.	the expansion of africanized honeybees from south america to the southwestern united states in <50 years is considered one of the most spectacular biological invasions yet documented. in the american tropics, it has been shown that during their expansion africanized honeybees have low levels of introgressed alleles from resident european populations. in the united states, it has been speculated, but not shown, that africanized honeybees would hybridize extensively with european honeybees. here w ...	2005	15937139
temporal pattern of africanization in a feral honeybee population from texas inferred from mitochondrial dna.	the invasion of africanized honeybees (apis mellifera l.) in the americas provides a window of opportunity to study the dynamics of secondary contact of subspecies of bees that evolved in allopatry in ecologically distinctive habitats of the old world. we report here the results of an 11-year mitochondrial dna survey of a feral honeybee population from southern united states (texas). the mitochondrial haplotype (mitotype) frequencies changed radically during the 11-year study period. prior to im ...	2004	15212385
