“…These results are consistent with those shown by Pinceel et al (2017) and by Beladjal & Mertens (2017), who investigated anostracan reproductive strategies with regard to the ''habitat uncertainty'' typical of temporary environments. In particular, anostracans show a high degree of adaptation to the unpredictability of the hydroperiod in temporary waters which includes a temporally differentiated egg hatching, different dimensions of embryos at different inundation times, production of variably sized offspring within each clutch and production of larger clutches of smaller eggs from parents inhabiting more uncertain habitats.…”

We present a summary of responses to our call among scientists working on Anostraca to commemorate the late Professor Graziella Mura, a pioneer of modern studies on this group of animals. Colleagues from all over the world promptly answered and contributed their works among which we selected the fourteen papers published in the Hydrobiologia Special Volume ''New Challenges in anostracan research: a tribute to Graziella Mura''. Although Anostraca are widespread globally, they are among the least known taxonomic groups. Although some biogeographical data are available for some species and higher taxa, we are still far from a clear understanding of the phylogeny, ecology and biogeography of the order. The papers collected in this Special Volume are therefore intended to represent a step ahead to solve phylogenetic and ecological issues relative to this charming group of crustaceans.

“…Plates were randomly positioned in a temperature-controlled incubator at 20°C under continuous light (full spectrum, 4,000 lux, lamp type Osram L 8 W/640; Osram, Rotterdam, The Netherlands). These inundation conditions corresponded to optimized hatching conditions for the investigated populations of this species (Pinceel et al 2017a). Hatching was evaluated at 12-h intervals until no new hatching occurred for 32 h. After each evaluation of hatching, plates were re-randomized within the incubator.…”

“…Similar results have been reported for other zooplankters. Pinceel et al (2017) observed decreased hatching fractions in dormant embryos of natural populations of Branchinella longirostris (Anostraca) and Paralimnadia badia (Spinicaudata) along an aridity gradient where the probability of reproductive success was progressively lower.…”

An in-depth look at the basic aspects of dormancy in cyclic parthenogenetic organisms is now possible thanks to research efforts conducted over the past two decades with rotifer dormant embryos. In this review, we assemble and compose the current knowledge on four central themes: (1) distribution of dormancy in animals, with an overview on the phylogenetic distribution of embryo dormancy in metazoans, and (2) physiological and cellular processes involved in dormancy, with a strong emphasis on the dormant embryos of cyclically parthenogenetic monogonont rotifers; and discussions of (3) the selective pressures and (4) the evolutionary and population implications of dormancy in these animals. Dormancy in metazoans is a widespread phenomenon with taxon-specific features, and rotifers are among the animals in which dormancy is an intrinsic feature of their life cycle. Our review shows that embryo dormancy in rotifers shares common functional pathways with other taxa at the molecular and cellular level, despite the independent evolution of dormancy across phyla. These pathways include the arrest of similar metabolic routes and the usage of common metabolites for the stabilization of cellular structures and to confer stress resistance. We conclude that specific features of recurrent harsh environmental conditions are a powerful selective pressure for the fine-tuning of dormancy patterns in rotifers. We hypothesize that similar mechanisms at the organism level will lead to similar adaptive consequences at the population level across taxa, among which the formation of egg banks, the coexistence of species, and the possibility of differentiation among populations and local adaptation stand out. Our review shows how studies of rotifers have contributed to improved knowledge of all of these aspects.
