    Regulation of Doublesex1 Expression for Environmental Sex Determination in the Cladoceran Crustacean Daphnia by Yasuhiko Kato, Hajime Watanabe

    Published 2022-04-01
    “…The cladoceran crustacean Daphnia produces only females by parthenogenesis in a healthy population. However, in response to environmental declines such as crowding and lack of foods, it produces eggs destined to become males that are genetically identical to females. …”

    VULTURES: EXEGESIS OF A SYMBOL by Maura Andreoni

    Published 2016-12-01
    “…</p><p class="Predefinito">In the ancient Mediterranean civilizations, they have been carved in some of the most ancient bas-reliefs of the history by stone age people; were sacred to Egyptians, who even took them as symbol of gods; in the classical times they were supposed to be all feminine and breed by parthenogenesis, and therefore appreciated by some early Christian authors, who came to comparing them even to the Virgin Mary; they have been studied and described by ancient scientists, naturalists, philosophers, playwrights; involved in many of the most enduring Greek and Roman myths and legends; many parts of their body were considered as a medicine or even a talisman for happiness; and they were so proverbial for Romans to become even one of the symbols of the founding of Rome itself.…”

    A tale of swinger insects: Signatures of past sexuality between divergent lineages of a parthenogenetic weevil revealed by ribosomal intraindividual variation. by Marcela S Rodriguero, Sonia A Wirth, Josefina S Alberghina, Analía A Lanteri, Viviana A Confalonieri

    Published 2018-01-01
    “…Investigation of intraindividual variation in ITS1 sequences through cloning and posterior sequencing suggested that mating between both groups most likely occurred in the Paranaense Forest after a secondary contact, which led to fixed heterozygotes as a consequence of parthenogenesis. Otherwise, sexual segregation would have disrupted multilocus genotypes. …”
