AbstractDespite the iconic roles of coelacanths, cycads, tadpole shrimps, and tuataras as taxa that demonstrate a pattern of morphological stability over geological time, their status as living fossils is contested. We responded to these controversies with a recommendation to rethink the function of the living fossil concept (Lidgard and Love in Bioscience 68:760–770, 2018). Concepts in science do useful work beyond categorizing particular items and we argued that the diverse and sometimes conflicting criteria associated with categorizing items as living fossils represent a complex problem space associated with answering a range of questions related to prolonged evolutionary stasis. Turner (Biol Philos 34:23, 2019) defends the living concept against a variety of recent skeptics, but his criticism of our approach relies on a misreading of our main argument. This misreading is instructive because it brings into view the value of three central themes for rethinking the living fossil concept—the function of concepts in biology outside of categorization, the methodological importance of distinguishing parts and wholes in conceptualizing evolutionary phenomena, and articulating diverse explanatory goals associated with these phenomena.

AbstractThe presence of non-cladoceran branchiopods was detected in only 16 out of 83 temporary freshwater ponds of SW Portugal, which were recently sampled by the authors and other researchers. Two anostracans, Branchipus cortesi and Chirocephalus diaphanus; two spinicaudatans, Cyzicus grubei and Maghrebestheria maroccana; and one notostracan, Triops cancriformis mauritanicus, were identified. All taxa are new records locally, and all but C. grubei and T. c. mauritanicus are reported for the first time from Portugal. La presence de Branchiopodes non Cladoceres a ete detectee dans 16 seulement des 83 mares temporaires d'eau douce du SO du Portugal, qui ont ete recemment echantillonnees par les auteurs et d'autres chercheurs. Deux Anostraces, Branchipus cortesi et Chirocephalus diaphanus, deux Spinicaudata, Cyzicus grubei et Maghrebestheria maroccana, et un Notostrace, Triops cancriformis mauritanicus, ont ete identifies. Tous les taxa sont nouveaux pour la faune locale et tous, sauf C. grubei et T. c. mauritanicus, sont signales pour la premiere fois du Portugal.
