Darwinulid Ostracods: Ancient Asexual Scandals or Scandalous Gossip?,atus. The evidence for the darwinulid ostracods is as yet inconclusive. Recent males have been found in a single species, but their functionality is uncertain and their morphology highlights the erroneous assignment of male status to a single individual of ., presently the best candidate for an anci

Parthenogenesis in Oribatid Mites (Acari, Oribatida): Evolution Without Sex,A high number (∼10%) of oribatid mite species reproduces via parthenogenesis, presumably by terminal fusion automixis with holokinetic chromosomes and an inverted sequence of meiotic divisions. Several of the old taxa of oribatid mites likely have radiated while being parthenogenetic. Many species o

Bdelloid Rotifers: Progress in Understanding the Success of an Evolutionary Scandal,lloid rotifers appear to be an exception to the general rule that multicellular eukaryotes that abandon sex are doomed to early extinction, and an understanding of their biology may reveal how they have avoided the fate of other asexual lineages. Here, we discuss aspects of the ecology, physiology,

Sex Loss in Monogonont Rotifers, eggs, which are able to survive adverse periods that typically occur every year. Their cyclically parthenogenetic life-cycle is believed to retain the advantages of recombination while minimizing the cost of sex. However, this life cycle is also thought to be unstable due to periodic loss of sexual

Cyclical Parthenogenesis in ,: Sexual Versus Asexual Reproduction, We first focus on the cyclically parthenogenetic life cycle of ., the phylogenetic backgrounds of this reproduction mode, and how cyclical parthenogenesis impacts the genetic structure of . populations. Further, we discuss the advantages of sex. Finally, we change perspective and discuss evolution

Thelytoky in Hymenoptera with , and , as Case Studies, and economic functions. All Hymenoptera have a haplodiploid mode of reproduction. Males always develop from unfertilized eggs and are haploid. Females are always diploid and can develop from both fertilized and unfertilized eggs. Within haplodiploidy, arrhenotoky is the most common mode of reproduc

Sperm-Dependent Parthenogenesis and Hybridogenesis in Teleost Fishes,ure sperm-dependent parthenogenesis (gynogenesis) without or with different amounts of paternal leakage to hybridogenesis with hemiclonal diploid gametogenesis or genome elimination followed by meiosis (meiotic hybridogenesis). All of these phenomena are of hybrid origin..Many of these fish form com
