The paper reports the discovery of exotic catenulid flatworm species in a temperate botanic garden greenhouse and provides molecular evidence for their phylogenetic placement.

This study shows that excessive feeding in flatworms leads to the formation of colony-like body plans through changes in growth rates, without requiring new developmental programs or adaptive benefits.

This study investigates the evolution of Wnt signaling in flatworms, revealing gene losses and expression divergence that inform the evolutionary origins of regeneration.

Degenerate COI primers combined with histology, karyology and transcriptomics raise the known Croatian freshwater planarian species from eight to sixteen and describe Dendrocoelum pigmentatum sp. nov.

The paper surveys catenulid diversity in Central and Western Europe, focusing on Poland, using molecular markers to infer phylogeny and identify taxonomic challenges.

The paper describes a spontaneous developmental error in flatworms leading to double-headed worms with reversed body axis polarity, which can regenerate normally.

This study shows that whole-body regeneration in a flatworm occurs without conventional neoblasts, challenging the idea that neoblasts are essential for regeneration.

The paper analyzes Fox gene expansions in flatworms, finding multiple independent expansions and lineage-specific adaptations.

The paper identifies conserved genes involved in shell formation in brachiopods and molluscs, showing their orthologs in related phoronids and bryozoans, and finds gene loss in the latter groups.

This study describes Hox gene expression patterns during the embryonic and larval development of Phoronopsis harmeri, finding no expression during embryonic stages and delayed expression in larval structures.

This study examines Hox gene expression in postmetamorphic juveniles of Terebratalia transversa to assess changes in expression patterns and collinearity after metamorphosis.
