“…In general, individuals of the same morphotype across androgenetic Corbicula share the same mitochondrial and nuclear haplotypes (Park and Kim, 2003;Lee et al, 2005;Hedtke et al, 2008;Pigneur et al, 2011a, b). However, mitochondrial lineages discordant with morphology have been reported in several populations of Corbicula in Asia, America and Europe (Park et al, 2002;Pfenninger et al, 2002;Lee et al, 2005;Hedtke et al, 2008;Pigneur et al, 2011b;see Figure 3). For example, invasive forms in the Americas and Europe are fixed across most of their range for unique mitochondrial haplotypes, but, in some populations, individuals of one morphological form harbor the mitochondrial COI sequence of the other form (for example, between forms A and B, B and C or R and S; Pfenninger et al, 2002;Lee et al, 2005;Hedtke et al, 2008;Pigneur et al, 2011b).…”

“…Ishibashi et al (2003) concluded that, in Corbicula, unreduced biflagellate sperm could be considered indicative of androgenesis. The presence of biflagellate sperm in the invasive lineages in the Americas (Lee et al, 2005; Table 2 and Figure 3) and Europe (Pigneur et al, 2011b; Table 2 and Figure 3) suggests that androgenesis is the most likely reproductive mode in invasive Corbicula.…”

“…Mitochondrial phylogenies have revealed that the androgenetic clams of the genus Corbicula are polyphyletic, including 3 or 4 clades Figure 2 Schematic illustration of mitochondrial genome capture and fixation of mixed cytonuclear genome in the case of the European Corbicula lineages forms R and S Pigneur et al, 2011b). The ploidy of forms R and S is still uncertain (2n or 3n), but the general mechanism of mitochondrial capture remains the same in the different cases.…”

“…of androgenetic lineages (Lee et al, 2005;Glaubrecht et al, 2006;Hedtke et al, 2008;Pigneur et al, 2011b; Figure 3). Many of these authors agree, however, that mitochondrial phylogenies poorly resolve taxonomic relationships among freshwater Corbicula lineages and may even constitute a 'pitfall' by pooling divergent nuclear lineages together (Park and Kim, 2003;Lee et al, 2005;Hedtke et al, 2008;Pigneur et al, 2011b). A combination of nuclear and mitochondrial data is therefore required to elucidate the relationships and evolutionary origin of androgenetic Corbicula lineages.…”

“…Automictic production of unreduced sperm could occur through several proposed mechanisms, and each of these will have different expectations for the genetic consequences: (i) pre-meiotic doubling of DNA during spermatogenesis (Komma and Endow, 1995;Haccou and Schneider, 2004); (ii) fusion of sperm after meiosis (McKone and Halpern, 2003) and (iii) abortive cytokinesis during meiosis (Komaru et al, 1997). Any viable hypothesis for the production of unreduced sperm in Corbicula must consider both the maintenance of not just diploid, but triploid (and maybe tetraploid) sperm, and the observation of heterozygosity across nuclear loci (Hedtke et al, 2008;Pigneur et al, 2011b). Both apomixis and pre-meiotic doubling of the chromosomes would result in the maintenance of heterozygosity over time (Haccou and Schneider, 2004).…”

Among the asexual reproductive modes, androgenesis is probably one of the most astonishing and least studied mechanisms. In this 'paternal monopolization', the maternal nuclear genome fails to participate in zygote development and offspring are paternal nuclear clones. Obligate androgenesis is known in only a few organisms, including multiple species of clam in the genus Corbicula. Corbicula is a good system to review the evolutionary consequences of this 'all-male asexuality' because the cytological mechanisms of androgenetic reproduction have been described. In Corbicula, sperm are unreduced and, after fertilization, the maternal nuclear chromosomes are extruded as two polar bodies. Hermaphroditic lineages of Corbicula have a worldwide distribution and seem to reproduce through androgenesis, whereas their sexual relatives have restricted ranges. The invasive success of these androgenetic Corbicula lineages may be linked to their asexual mode of reproduction. We review the phenomenon of androgenesis, focusing on evolutionary perspectives, using the genus Corbicula as an exemplar system.

Sexual reproduction is the primary mode of reproduction in eukaryotes, but some organisms have evolved deviations from classical sex and switched to asexuality. These asexual lineages have sometimes been viewed as evolutionary dead ends, but recent research has revealed their importance in many areas of general biology. Our review explores the understudied, yet important mechanisms by which sperm‐dependent asexuals that produce non‐recombined gametes but rely on their fertilization, can have a significant impact on the evolution of coexisting sexual species and ecosystems. These impacts are concentrated around three major fields. Firstly, sperm‐dependent asexuals can potentially impact the gene pool of coexisting sexual species by either restricting their population sizes or by providing bridges for interspecific gene flow whose type and consequences substantially differ from gene flow mechanisms expected under sexual reproduction. Secondly, they may impact on sexuals' diversification rates either directly, by serving as stepping‐stones in speciation, or indirectly, by promoting the formation of pre‐ and postzygotic reproduction barriers among nascent species. Thirdly, they can potentially impact on spatial distribution of species, via direct or indirect (apparent) types of competition and Allee effects. For each such mechanism, we provide empirical examples of how natural sperm‐dependent asexuals impact the evolution of their sexual counterparts. In particular, we highlight that these broad effects may last beyond the tenure of the individual asexual lineages causing them, which challenges the traditional perception that asexual lineages are short‐lived evolutionary dead ends and minor sideshows. Our review also proposes new research directions to incorporate the aforementioned impacts of sperm‐dependent asexuals. These research directions will ultimately enhance our understanding of the evolution of genomes and biological interactions in general.

Differences in local habitat conditions are often implicated as drivers for morphological and genetic divergence in natural populations. However, there are still relatively few studies regarding how divergent habitats influence patterns for morphotypes and genetic lineages in aquatic invertebrates. In this study, we explored the morphological patterns, genetic divergence, and distributions of a bivalve, Corbicula fluminea, in a lotic–lentic system. Sampling locations included lotic, ecotone, and lentic habitats. First, we found two lineages (Lineages A and B) with significant genetic divergence that primarily corresponded to two morphotypes (Morphs D and C) of C. fluminea. Lineage A consisted of 88.68% Morph D (shell sculpture: 8–14 ridges/cmsh) and 11.32% Morph C (shell sculpture: 15 ridges/cmsh) individuals and had genetic similarity to invasive populations. Lineage B consisted of only Morph C (shell sculpture: 15–23 ridges/cmsh). Second, we revealed clear effects of habitat on the spatial distribution patterns for the two lineages of C. fluminea. Lineage A was dominant in lotic habitats, with a significantly higher density than that of Lineage B in these locations. Lineage B was dominant in lentic habitats. However, both lineages had their highest densities in the ecotone habitat, without clear dominance and no significant difference in density between groups. Individuals of Lineages A and B are different in shell morphology, which may be related to a benefit trade‐off between shell shapes that allow for rapid burrowing and holding position in different flow conditions. The distribution patterns indicate that Lineages A and B may not prefer uniquely lotic and lentic habitats, but each lineage is more tolerant to one habitat type, respectively. Generally, our study established a correlation among morphotypes, lineages, and different habitats for C. fluminea along a lotic–lentic gradient system, which has important implementations for fisheries management units and for understanding the role of habitat preference for this species in monitoring for pioneer dispersal in invasive species management.
