Free-living flatworms of the genus Macrostomum are small and transparent animals,
representing attractive study organisms for a broad range of topics in evolutionary …

Regenerative abilities vary dramatically across animals. Even amongst planarian flatworms,
well-known for complete regeneration from tiny body fragments, some species have …

Background Sex allocation is the distribution of resources to male or female reproduction. In
hermaphrodites, this concerns an individual's resource allocation to, for example, the …

The free‐living flatworm Macrostomum lignano is used as a model in a range of research
fields—including aging, bioadhesion, stem cells, and sexual selection—culminating in the …

Abstract Background The genus Macrostomum consists of small free-living flatworms and
contains Macrostomum lignano, which has been used in investigations of ageing, stem cell …

The free-living, simultaneously hermaphroditic flatworms of the genus Macrostomum are
increasingly used as model systems in various contexts. In particular, Macrostomum lignano …

Background Unlike most free-living platyhelminths, catenulids, the sister group to all
remaining flatworms, do not have eyes. Instead, the most prominent sensory structures in …

The planarian Schmidtea mediterranea can regenerate its entire body from small tissue
