The paradox of sex remains the queen of problems in evolutionary biology.

Titelblatt: "Der Spiegel" Why SexWaageSexual reproduction is widespread throughout the animal and plant kingdoms, but undercertain conditions remain costly compared to asexual reproduction. Sex creates a wide variety of genotypes on which natural selection can act, but it also breaks up favourable gene combinations. Asexuals have the ability to preserve their genome and to propagate genotypes that have a previous history of success.

In addition, asexuals can reproduce twice as fast as sexuals, because all, rather than half, of their offspring are themselves capable of reproduction. Although asexual reproduction offers several clear short-term advantages, ruling evolutionary theory dictates that the absence of a mechanism for rapid genetic change will direct clones persisting over long time frames into evolutionary dead ends. Several animal and plant groups nevertheless show a large incidence of asexual reproduction and some lineages might have been fully asexual for many millions of years.

EROS in Ostracods: Evolution of Reproduction with Oversized Spermatozoa in Ostracods
(Grant of the German Research Foundation, Co-PI with Dr. Renate Matzke-Karasz, LMU Munich, Germany, 2011-2013)

Giant sperm from Matzke-Karasz (2005)

Giant sperm from Matzke-Karasz (2005)

Recent cypridoidean ostracods (Podocopa) are living mainly in fresh or brackish water environments. They reproduce with filamentous giant sperm, reaching up to ten times the body length of the animal. A common origin of their reproduction with giant sperm is well supported by fossil evidence from the lower Cretaceous, speaking for an evolutionary success of this reproductive mode.

Considering the energetic costs related to production, transport and storage of giant sperm, the question about the advantages stands to reason. Hypotheses that have been put forward for other groups with giant sperm (e.g. copulatory plug, female cryptic choice or zygote nutrition) must be seen as ap-proximations, which are each applicable for at least a few of the regarding taxa. However, none of the existing hypotheses can be satisfactorily assigned to the situation on ostracods.

The present project outline features two hypotheses, of which one, hypothesis B, has been developed in consideration of the special anatomy of ostracods. The hypotheses are: (A) male freshwater ostracods developed giant sperm in order to fill the female receptacles and thus to prevent other males inseminating the female (aim: optimization of fertilization success) and (B) giant sperm help female freshwater ostracods to reduce the sperm transfer rate per time unit (aim: diversification of paternities). A lower sperm transfer rate not only reduces the absolute sperm number per completed insemination; female ostracods potentially have the opportunity to interrupt copulation by closing their valves. A low sperm transfer rate thus allows for an improved control of the number of sperms transferred by actively determining the copulation duration.

Evolution of extraordinary long female sperm ducts and a complex female reproductive system may have caused a selective pressure on males towards the evolution of giant sperm.

Quantifying Individual Fitness with Trojan Sex Chromosomes: an Ultimate Conservation Tool

Mosquito fish, Gambusia affinis

With an alarming decline in biodiversity, conservation biologists have been facing two pressing tasks: 1) protecting and recovering the populations of endangered species, and 2) controlling invasive pest species which threaten native biota. These two tasks usually require different theoretical and/or methodological frameworks.

Recently, the introduction of individuals, carrying ‘Trojan’ sex chromosomes (i.e. hormone-treated individuals whose sex has been reversed from their genotype), into wild populations has been proposed as a potential way of not only exterminating invasive pest species but also of saving endangered species. However, the ecology of individuals carrying Trojan sex chromosomes (i.e. sex-reversed individuals) and their offspring is virtually unknown. Thus, empirical work on the use of Trojan sex chromosomes is urgently required.

We will conduct the first comprehensive investigation quantifying the fitness of sex-reversed individuals and their offspring, using an invasive fish species. We will use three different approaches: morphological, endocrinological and behavioural measurements. This work will extend our knowledge of the intricate relationships among genes, hormones and phenotypic characters.  Importantly, it will explore the feasibility of introducing Trojan individuals into wild populations for conservation proposes. Therefore, our project will ensure that New Zealand remains a front runner in the field of conservation biology.

Gynogenesis as a dispersal strategy
(Funds of the EAWAG, PI with Dr. Jukka Jokela, EAWAG Zürich, Switzerland, Dr. Jouni Taskinen & Manuel Deinhard, University of Jyväskylä, Finland)

The Prussian carp, Carassius gibelio, was introduced to Europe from East Asia, probably as a triploid all-female gynogenetic lineage whose clonal reproduction relies on sperm from related species inducing the asexual egg development. Since its introduction, the Prussian carp invaded most of European fresh water systems and started developing diploid and tetraploid forms, males and sexual modes of reproduction. The mechanism of the observed changes is not well understood. Distribution patterns suggest that the Prussian carp is invasive and displaces its sexual sperm-donor, the European crucian carp (C. carassius).

We investigate the parasite community, ploidy and genetic structure of several European populations of successfully spreading gynogenetic Prussian carp, as well as of their sperm donor, the indigenous Crucian carp. Crossing experiments will give insights into the mechanism of gynogenesis.

Paternal introgression in the sperm-dependent parthenogen Poecilia formosa

Amazon molly

Amazon molly

The Amazon molly, Poecilia formosa, is an all-female species that reproduces gynogenetically: it produces unreduced eggs but needs sperm from a closely related sexual species to trigger the onset of embryonic development. Usually, the male genetic material is excluded from the oocyte and does not contribute to the offspring (clonal reproduction).

In very rare cases, however, this exclusion mechanism fails and the male genome fertilizes the egg leading to triploid individuals. We are interested in this form of paternal introgression because polyploidization is thought to drive evolution and speciation as it provides plenty of genetic material for differentiation. This additional genetic material might be especially valuable to P. formosa that - as a clonal organism - should suffer from an overall low genotypic variability and the accumulation of deleterious mutations.

We found, however, that the triploid clones of P. formosa have a low genetic variability and are most likely of monophyletic origin. We discovered a second level of paternal introgression when we recently found the first tetraploid P. formosa. Most likely it resulted from the fertilization of a triploid egg. We hypothesize that triploids could be important stepping stones to create tetraploids that (by segregation of chromosome sets) might have an important role in creating genotypic variation in the diploid lines of P. formosa. This would explain why in the field diploid P. formosa show a high clonal diversity.

In addition, diploids show another type of paternal introgression: supernumerary microchromosomes which might also contribute to high clonal diversity in diploids.

From Sex to Asex: A case study on interactions between sexual and asexual reproduction in a non-marine ostracod (Link)

Non-marine ostracod, Eucypris virens

Non-marine ostracod, Eucypris virens

An elevation in ploidy often accompanies the transition from sexual to asexual mode of reproduction, yet the ecological and evolutionary importance of ploidy in the maintenance of parthenogenetic populations is still not clear. We survey association of ploidy and geographic distribution of asexual and sexual European Eucypris virens and analyse its patterns in the perspective of lineage origin.

This freshwater ostracod has a wide geographic distribution and was found as diploid sexual, diploid asexual and triploid asexual. There have been repeated origins of both, diploid asexual and triploid lineages, and these share sexual ancestors. As a consequence of the exceptional cryptic divergence between sexual populations, asexual lineages come in a great variety of genetic backgrounds. Northern as well as southern sites are often occupied by clones of multiple origins, there is, however, a clear dominance of triploid asexuals in northern Europe. The scarce distribution of diploid asexuals despite common ancestry with triploid asexuals thus confirm the view that wider geographic distribution of triploids is rather due to elevated ploidy, which may be of hybrid origin, than asexuality.
