Impact of the nemertean Lineus viridis on its polychaete prey on an intertidal sandflattean in this intertidal area with a mean abundance of 14 individuals per square meter. Predator enclosure experiments in the field revealed that . preyed on predatory polychaetes. The preferred prey species was . others were . and .. These results were supported by a series of feeding experiments in

Neuroendocrine control of gonadogenesis in regenerating , (Heteronemertea)to determine whether the cerebral hormone also controls regenerative growth, as it does in other marine worms such as . (Polychaeta), we compared gonadogenesis with enterogenesis in regenerating . under the influence of, and withdrawn from the influence of, GIH. Experimental evidence is presented fo

Evolutionary relationships between mono- and polystiliferous hoplonemerteans: Nipponnemertes , “,” , Polystilifera. A brief survey of these features provides a basis for an analysis of possible evolutionary relationships between mono- and polystiliferous Hoplonemertea. It is suggested that ancestral enoplans possessed a rhynchocoel wall containing two muscle layers and a simple “protopolystilifero

Marine relatives of terrestrial nemerteans: The genus , Bürger, 1890 (Hoplonemertea) this identification is related to Bürger’s (1890) original description. The remaining four species can on present evidence neither be accepted as valid taxa nor regarded with certainty as synonymous with .; they are accordingly designated as nomina dubia. A comparison between . and the group I gene

Polymorphism in , (Abilgaard, 1806) revisitedhology shows that one of the varieties should be assigned the rank of species. The genetic differentiation is compared with a multivariate assessment of morphological distance between these forms, and it is concluded that the substantial genetic differentiation between the two species is not reflect

Hubrecht, Macfarlane, Jensen and Willmer: On the nature and testability of four versions of the neme of vertebrates. While all these authors accept certain homologies (i.e. vertebrate pituitary and notochord with nemertean proboscis invagination and proboscis sheath or mesoderm), there is considerable variation among them in the derivation of the vertebrate nervous system, sense organs and foregut
