Material was collected from the Oosterschelde near Yerseke, The Netherlands from a habitat characteristic for the subfamily Autolytinae (Polychaeta, Syllidae). The following features were used to characterize the specimens: type of stolonization, male

This study characterizes the macrobenthic gradients in Ria de Aveiro, Western Portugal. Ria de Aveiro is the meeting place of a number of river basins, resulting in a transition system of complex geometry, with channels running parallel to the coast line,

Artificial reef systems play an important role in the increase of natural production of biological marine resources and they have been deployed worldwide. In Portugal, seven artificial systems have been deployed along the southern coast of the Algarve.

The phylogeny of 31 autolytine taxa (Syllidae, Polychaeta, and Annelida) was estimated based on 16S rDNA and 18S rDNA sequences. Outgroups included 12 non-autolytine syllids and four other annelids from related groups. The phylogeny was used to trace
