Occasional sex in an ‘asexual’ polyploid hermaphrodite by D'Souza, Thomas G., Storhas, Martin, Schulenburg, Hinrich, Beukeboom, Leo W., Michiels, Nicolaas K.

“…Asexual populations are usually considered evolutionary dead–ends because they lack the mechanisms to generate and maintain sufficient genetic diversity. Yet,…”

The effect of ploidy level on fitness in parthenogenetic flatworms by D'SOUZA, THOMAS G., STORHAS, MARTIN, MICHIELS, NICO K.

“…Although polyploidy plays an important role in speciation, its impact on fitness is still debated. One problem is that its adaptive significance can only be…”

Sperm length and quality in sperm-dependent parthenogens by D'SOUZA, THOMAS G, BELLENHAUS, VERA, WESSELMANN, RAMONA, MICHIELS, NICO K

“…Is the male function of parthenogenetic hermaphrodites a historic remnant or an adaptive investment? In the first case, one would expect the male function to…”

Genetic signatures of occasional sex in parthenogenetic subpopulations of the freshwater planarian Schmidtea polychroa by D'SOUZA, THOMAS G., MICHIELS, NICO K.
