Ultrastructure of cerebral eyes in Oweniidae and Chaetopteridae (Annelida) – implications for the evolution of eyes in Annelida
BackgroundRecent phylogenomic studies have revealed a robust, new hypothesis of annelid phylogeny. Most surprisingly, a few early branching lineages...

Species and genetic diversity relationships in benthic macroinvertebrate communities along a salinity gradient
BackgroundSpecies- and genetic diversity can change in parallel, resulting in a species-genetic diversity correlation (SGDC) and raising the question...

Anterior sense organs in Sabellaria alveolata (Annelida, Sedentaria, Spionida) with special reference to ultrastructure of photoreceptor elements presumably involved in shadow reflex
The reef-building sedentary polychaete, Sabellaria alveolata , is well known for its specialized anterior end, the operculum, which is exposed to the...
