Annelida is an ecologically and morphologically diverse phylum within the Lophotrochozoa
whose members occupy a wide range of environments and show diverse life styles. The …

The advent of numerical methods for analysing phylogenetic relationships, along with the
study of morphology and molecular data, has driven our understanding of animal …

Background Annelida comprises an ancient and ecologically important animal phylum with
over 16,500 described species and members are the dominant macrofauna of the deep sea …

Systematics has developed rapidly during the past two decades. A multitude of new
methods and contributions from a diversity of biological fields including molecular genetics …

Caenogastropoda is the dominant group of marine gastropods in terms of species numbers,
diversity of habit and habitat and ecological importance. This paper reports the first …

Background Annelida is one of the major protostome phyla, whose deep phylogeny is very
poorly understood. Recent molecular phylogenies show that Annelida may include groups …

The phylogenetic position of Annelida within Metazoa was uncontroversial for a long time.
Ever since Cuvier (1817), the dominant hypothesis was the Articulata hypothesis, which …

Terebelliformia—“spaghetti worms” and their allies—are speciose and ubiquitous marine
annelids but our understanding of how their morphological and ecological diversity evolved …

Planktonic food webs were studied contemporaneously in a mesoscale cyclonic
(upwelling,∼ 13 months old) and an anticyclonic (downwelling,∼ 2 months old) eddy as …

The direction of evolution within Annelida has been a long and contentious debate since the
middle of the last century. Based on functional morphology two hypotheses were …
