متن کاملEvolution and comparative ecology of parthenogenesis in haplodiploid arthropods
Changes from sexual reproduction to female-producing parthenogenesis (thelytoky) have great evolutionary and ecological consequences, but how many times parthenogenesis evolved in different animal taxa is unknown. We present the first exhaustive database covering 765 cases of parthenogenesis in haplodiploid (arrhenotokous) arthropods, and estimate frequencies of parthenogenesis in different tax...
متن کاملThe evolution of geographic parthenogenesis in Timema walking-sticks.
Phylogenetic studies of asexual lineages and their sexual progenitors are useful for inferring the causes of geographical parthenogenesis and testing hypotheses regarding the evolution of sex. With five known parthenogens and well-studied ecology, Timema walking-sticks are a useful system for studying these questions. Timema are mainly endemic to California and they exhibit the common pattern o...
