In the freshwater planarian Dugesia polychroa (Tricladida, Paludicola), both animals fulfil the male and female role simultaneously in any given copulation. This study presents the first detailed account of the copulatory behaviour, timing and freque

Do parasites and accumulation of deleterious mutations act synergistically in balancing the costs of sex? We addressed this possibility in the freshwater planarian flatworm Schmidtea polychroa. Sexual and parthenogenetic forms of this species sometim

We present a karyotypic survey of the European freshwater planarian Dugesia polychroa, detailing frequencies of diploid and polyploid forms from 35 localities in seven countries. In this hermaphroditic species, diploids reproduce sexually and polyplo

1. It is shown that reallocation of resources from dying offspring to their surviving siblings leads to significant reductions of fitness losses due to early developmental errors. 2. The reason resource reallocation can improve offspring fitness is b

Asexual populations are usually considered evolutionary dead-ends because they lack the mechanisms to generate and maintain sufficient genetic diversity. Yet, some asexual forms are remarkably widespread and genetically diverse. This raises the quest

The genomes of many species have been shown to contain loci composed of tandemly repeated short DNA sequences known as microsatellites or simple sequence motifs (Tautz & Renz 1984). Allelic variation in copy number of the repeat unit renders these lo

For highly purified preparations of neoblasts, density gradient centrifugation in Percoll solutions (Pertoft et al., 1978) was applied to cell suspensions obtained by disintegrating Dugesia polychroa (Schmidt) in culture medium contained in a Dounce

Restitution bodies are more or less spherical cell aggregates covered with an epithelial layer and ranging from 10 to 500 µm in diameter. They were first observed by Freisling & Reisinger (1958) who pressed planarians through fine mesh gauze and sus

A high decrease in fertility was earlier reported in Dugesia polychroa after induced self‐fertilization. Similar results have now been obtained in Planaria torva from a comparative analysis of cocoon fertility between cross‐ and self‐pairs. The
